10.1 Introduction

Cowpea is a typical warm season crop adapted to tropics. It is grown both for its tender pod and dry seed that is used as pulse for culinary purposes. The pods are rich in protein, vitamin B and minerals. It is also used as a fodder and green manure crop. On dry weight basis the cowpea seeds contain 23.4 % protein, 1.8 % fat and 60.3 % carbohydrates. Most probable progenitor of cowpea is Vigna unguiculata var mensensis. It is grown as a catch crop that is drought tolerant and sensitive to water logging. Being a legume crop, cow pea fits well in different inter-cropping systems. It is mainly of two types. Asparagus bean/yard long bean/snake bean (Vigna sesquipedalis) has 30-90 cm long fleshy pod with elongated kidney shaped 8-12 mm long seeds. It is late maturing variety. While catjang bean (Vigna catjang) has 7-13 cm long pods with 5-6 mm kidney shaped seeds. Pulse type of cowpea is Vigna uniguiculata var radiate and dual-purpose cowpea is Vigna uniguiculata var cylindrica.

Introduction to Competitive Analysis

Competitive analysis is a crucial component of strategic planning and business decision-making. It involves assessing and understanding the competitive landscape in which a company operates. Here are some key points to consider when introducing competitive analysis:

Competitive analysis is the process of evaluating and analyzing the strengths and weaknesses of current and potential competitors in a specific market or industry.

Purpose: The primary purpose of competitive analysis is to gain insights into competitors' strategies, capabilities, and market positioning. It assists businesses in pinpointing opportunities, mitigating risks, and formulating effective strategies to surpass their competitors.

Information sources: Competitive analysis relies on gathering information from various sources. These include publicly available data, industry reports, competitor websites, customer reviews, social media, and market research.

Introduction Livestock plays a vital role in rural economy. Apart from milk, which is a significant economic contributor, efficient use of livestock resources and byproducts like Manure/dung in biogas systems can help generate localised clean cooking energy for rural masses. At the same time, biogas spent slurry; a by-product of biogas plant is a potential source of major and micronutrients besides organic matter. Its proper utilisation after processing has a vast potential in meeting the nutrient requirement of the crops and thereby reducing use of chemical fertilizers besides providing sustenance to soil health. It is estimated that about 443.5 lakh tonnes of solid bio-slurry could be made available from dairy animals. This bio slurry can be processed to produce bio fertilizers which can meet the India’s requirement of NPK and micronutrients (Fe, Mn, Zn, Cu) by about 4.5% and 0.4% respectively. Vermicomposting is the best technique to convert livestock waste into a resource. In India livestock manure is managed basically in three ways:

A. Majority cases dung/manure excreted by livestock are removed and dumped into heaps nearby cattle sheds. The heaps remained for some time when they get converted into manures, which are spread subsequently in the fields as an organic matter.

B. Manure/dung is utilized for energy purpose in village level where the dung is made into small cakes and dried and later on used as a fuel for cooking purposes. This is a great wastage of organic matter which needs to be utilized or managed in other ways so that both the energy and manure can be obtained from the livestock waste.

C. This method of manure utilization is popularized both by central and state government through bio-gas plant where manure is used for the production of methane under anaerobic (lack of oxygen) conditions. The methane gas is used for cooking purpose as well as the slurry after methane extraction is used as farm manure. This management and technique reduce methane emission in environment utilized the methane for cooking purpose and at the same time the valuable waste is utilized as a farm manure.

Introduction

The term “Remote Sensing” was coined in 1950s by Ms. Evelyn Pruitt, a geographer with the U.S. Office of Naval Research, and the term is now commonly used to describe as the science and art of identifying, observing, and measuring an object on the earth surface, without having any direct contact. This process involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials through which they may be identified and categorized by class/type, substance, and spatial distribution (National Aeronautics and Space Administration—NASA). Remote sensing technology has been widely applied in various applications such as water resources, agriculture, geological studies, forestry, land use, resource exploration, etc.

Elements of Remote Sensing

The remote sensing process involves an interaction between the incident radiation and the targets of interest, exemplified by the use of imaging systems in which the following seven elements are involved; however, remote sensing also involves sensing of emitted energy and using non-imaging sensors

Introduction

Rainfall is one of the climatic variables that varies very highly spatially and temporally. Understanding this micro-level variation is a crucial indicator for planning future water requirements and preparing for management strategies. Numerous researchers have delved into the distribution, variability, and trends of rainfall across diverse spatial scales, ranging from global to regional and basin levels. Nair et al. (2014) analyzed the rainfall trend and seasonality index for Kerala state in India over the last 100 years. The rainfall trend was found to be decreasing significantly in almost all the regions of the state. Nischitha et al. (2013) provide insights into the spatial and temporal variability of daily monsoon rainfall in the Tunga and Bhadra River basins in Karnataka state. Paradkar et al. (2019) evaluated the pattern of weekly rainfall by using statistical parameters such as mean, standard deviation, skewness, and kurtosis for five stations in Pratapgarh district.

Geographical Information System (GIS) proved to be an effective tool in handling information and analyzing rainfall patterns, providing visual representations, and facilitating the decision-making process (Kadir et al. (2016) and Rao et al. (2017)). Anand et al. (2020) analyzed the long-term spatial and temporal trends of rainfall in the Lower Bhavani basin in Tamil Nadu, India using GIS and statistical methods. Earls et al. (2007) compared different interpolation methods such as Inverse Distance Weighting, Spline, and Kriging (ordinary and universal) to generate a 30 m representation of the rainfall data. Spatial interpolation techniques perform differently and their evaluation should not rely solely on quantitative assessment. Wu & Hung (2016) compared the performance of three spatial interpolation techniques i.e., IDW, kriging, and spline using quantitative assessment, 2D visualization, and 3D visualization. IDW and kriging performed similarly in terms of quantitative assessment, while spline performed worse. IDW and spline performed similarly in 2D visualization, while kriging showed different behavior. Kriging was observed to be an inexact interpolation in 3D visualization, while spline tended to create extreme values along the edges of the study area. Some studies discovered that the accuracy of Kriging in the study area is higher than that of IDW or Thiessen interpolations (Earls et al. 2007; Song et al. 2008; Chen et al. 2010). GIS applications have the capability to integrate spatial data and non-spatial data like rainfall and to visualize, model, and analyze how rainfall distribution varies across space and over time, providing insights into climate change, water resource management, agricultural planning, and disaster management. The present study aims to analyze annual rainfall data pertaining to Kerala state in the GIS environment.

Okra is a tropical vegetable cultivating for its tender fruits. It is one of the major vegetable crops in India which can be grown in summer as well as rainy season. Fruits are rich in vitamin A, vitamin C and minerals like calcium, phosphorus, iodine, iron, and potassium. Dry fruit skins and fibers are valued for manufacture of paper and card boards. The processed product, dehydrated okra plays a considerable role in export earnings. Dried seeds of okra found to have 20-24 percent protein and 13-22% edible oil hence, used for edible oil production. Mucilaginous stem is used for clarification of cane juice for preparing jaggery. Roasted ground seed are used as coffee substitute.

Cultivated okra is believed to be originated in tropical and subtropical Africa and phytogeographic studies indicated that it arose in Abyssinian region (Ethiopia). However, existence of large number of related species with wide variability and dominant characters suggested India as the secondary centre of origin. Some researchers suggested Hindustani centre of origin mainly India, Pakistan, & Burma.

Morphology and Pollination

Okra is an erect robust herbaceous annual with green or green with reddish tinged stem. Leaves are alternate, 3-7 lobbed, palmate, hirsute and serrate. Flowers are solitary, bisexual, axillary, peduncle is 2 cm long, epicalyx is up to 10 and bracteoles narrow and hairy. Calyx is fused with corolla hence falls with corolla after anthesis. Petals are 5, separate, yellow coloured with crimson spot on claw. Staminal column consists of numerous stamens (80-120) which are united to the base of the petals. Ovary is superior, stigma is small, 5-8 fid and deep red. Fruit is pyramidal and oblong beaked capsule, longitudinally furrowed, hirsute or glabrous, dehisce longitudinally when ripe. Seeds are dark green to dark brown, round and tuberculate.

Introduction

Agriculture is the back bone of Indian economy. About 18.8 percent (2021-22) of the national income originates from the agriculture sector. Approximately 60 percent of India’s population is directly or indirectly dependent on agriculture for livelihood. A large number of important industries like jute, textiles, edible oils, tobacco, sugar etc. receive the raw materials produced by agriculture sector. India occupies second position in the production of fruits and vegetables in the world after China (National Horticulture Database 2019 2020) It is grown almost in all the states of the country.

Cauliflower (Brassica oleracea L. var. botrytis) like all other Brassicaceae family crops has descended through introgression, mutation, human selection and adaptation from a single wild predecessor Brassica oleracea L. var. sylvestris which is still found growing in western and southern Europe and North Africa. The name cauliflower consists of two Latin words namely ‘caulis’ means cabbage and ‘floris’ means flower. It is grown throughout the country for its highly suppressed ‘prefloral fleshy apical meristem’ called “Curd” which is used as vegetable, soup and for pickling (Choudhury, 2006). Cauliflower is the pride of cole crops because of its good taste, flavour and nutritional value. It contains good amount of vitamins like vitamin A, vitamin C and fair amount of proteins and fibers. The cauliflower is also a good source of minerals like Ca, Mg, P, Fe, Na, and S.

Introduction

The most significant commercially grown fruit crop in the country is the mango (Mangifera indica L.), which belongs to the Anacardiaceae family. It’s known as the “king of fruits.” Mango cultivars can be found in the greatest variety in India. Mango farming is thought to have begun in South East Asia. Since about 6,000 years ago, mango has been grown in south Asia.Mango is native to South Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics.

The major mango-growing states are Andhra Pradesh, Uttar Pradesh, Karnataka, Bihar, Gujarat and Tamil Nadu. Andhra Pradesh rank 1st in area, whereas Uttar Pradesh rank 1st in production and productivity. Andhra Pradesh, Uttar Pradesh, Bihar, Karnataka, Maharashtra, West Bengal and Gujarat together contribute for about 82% of the total production in India.

India to become the second largest fruit producer in the world, after china, with a production of 102481 thousands metric tonnes of fruits from an area of 6930 thousands hectares in 2020-21.The fruit is grown in India, the total area under mango cultivation was 2317 thousand hectare with an annual production of 20386 thousand metric tonnes.(NHB 2020-21).

Mango is well adopted in tropical and sub-tropical climates but it can be grown up to 1,100 meters above sea-level. There should not be humidity, rain or frost during flowering. The temperature between 24 and 270C is ideal for its cultivation. Higher temperature during fruit development and maturity gives better quality fruits. The areas expressed frequent showers and high humidity is prone to many pests and diseases. Thus it can grow best in regions with a rainfall between 25cm and 250 cm. Regions having bright sunny days and moderate humidity during flowering is ideal for mango growing.The farmers 92.20 per cent had problems of pests in their mango trees. The most common pests were the mango seed weevil 48.10 per cent, fruit fly 36.40 per cent, trips 1.30 per cent, aphids 1.30 per cent and the most common diseases were the powdery mildew 46.80 per cent, anthracnose 18.20 per cent and scab 2.60 per cent (Gitonga,2010).

Introduction

NITI Policy Paper No.1/20017 reveals details of the concept and time frame as how to double the income of the farmers. The policy paper emphasizes in increase in agriculture productivity, improvement in total factor productivity, diversification towards high value crop, and increase in crop intensity, increasing terms of trade for farmers and shifting cultivators to non-farm and subsidiary activities. The well thought and planned program for doubling the income of the farmers reflecting dream or reality. We have farmers of different types like, small. Marginal and large farmers, resource rich and resource poor farmers, farmers of irrigated and non-irrigated zones, tribal and non-tribal farmers , trained and untrained farmers and progressive and non-progressive farmers. The farmers and their economic structure are quite different from place to place even within district. NSSO data on consumption expenditure survey (2011-12) reveal that more than one-fifth of households with self employment in agriculture and their principal occupation were having income less the poverty line.

Milk Production Scenario

Milk is primary source of protein and lactoseDairy farming is considered to be a whole environment of reciprocal relations and dependency reproduction and protection of social values. In worldwise dairy cows count up to 264 millions producing 600 million tones of milk every year. The global average for milk production is approximately 2200 litters/cow. Cattle population of world is 1009.69 millions heads (FAO, 2019) and highest milk producing countries are India, USA, China, Pakistan and Brazil. In case of consumption of milk India tops in the world followed by EU, USA and China. The per capita consumption of milk is highest in the country of Belarus followed by Ukraine and New Zealand. India is ranked 7th in the world in this respect. In India total cattle population is 306.70 millions. The state of Odisha constitutes 1.19% of the total cattle population of India. The level of milk production of India is reported to be 198.2 metric million tones. The per capita availability of milk in India is 427 gms/day (2021) and highest being in Punjab followed by Rajasthan. In case of Odisha the per capita milk availability is 143 gms and in milk production the district Cuttack top the list followed by Ganjam and Jagatsinghpur.

Introduction

In view of the present Indian agriculture scenario, farmer producers organisations (FPOs) are emerged as a most appropriate institutional form to mobilize small and marginal farmers ,improved their access to technology, inputs and markets. As per the report of National Council on Farmers, these organisations are mainly promoted to combine the advantages of decentralized production and centralized services, post harvest management, value addition and marketing. (NCF,2004). In order to meet the dream of Atmanirbhar Bharat and to make farmers atmanirbhar, Farmer Producers’ Organizations (FPOs) is an appropriate form to mobilize them. Recently Government of India has announced a budgetary provision of 4496.00 crore for five years for promotion of 10,000 FPOs.(Cabinet Committee on Economic Affairs,CCEA2020)

Also to improve agricultural productivity and income of the farmers, it is necessary to develop an entrepreneurial culture among the member farmers of an organisation. To make this organisational approach more successful, member farmers need to develop planning ability, decision making abilitiy, managerial qualities ,scientific attitude, organisational skills, participatory skills etc. The member farmers as an agripreneur should possess knowledge about improved production techniques, markets, consumer preferences , schemes, credit availability, policy advocacy to enterprise effectively under FPO.

Introduction

Novel Corona Virus 2019 (COVID 19) has impacted the human race very badly than any other disease in twenty first century. Almost every country on this planet was affected by this virus. The condition is more severe in developed countries.

So when it All Started?

There were reports that the medical professionals of Wuhan in China informed the government that there is some mysterious pneumonia like disease which is spreading very fast and affected the doctors and other paramedical staff who are attending the patients. When the situation became serious it was declared as outbreak of epidemic and first case of COVID 19 was declared in Wuhan China on 31st December 2019. Wuhan is one of the main business centres of china and there was regular movement of domestic and international visitors to that place. Till the problem was identified and communicated to other agencies, the spread of virus was already there in other parts of china and world specially Europe and USA.

World Health Organisation (WHO) declared COVID 19 as pandemic on 11 February 2020. Countries like USA criticized WHO for delay in identifying the disease and declaring it a pandemic.The damage was already done due to its spread in other countries. In India first reported case of COVID 19 was on 30th January at Kerala. However, considering the possible danger of this disease, Indian Government took primitive measure to contain the spread of Virus and announced Nationwide Lockdown 1.0 on 23rdMarch 2020. Similarly, Lockdown 2.0, 3.0, 4.0 were announced on 14 April, 3rd May and 17th may respectively.

Introduction

India is bestowed with a lot of potentials to produce a variety of organic products due to its diversified agro-climatic regions and this is very true in case of Dehradun district of Uttarakhand. It offers a variety of geographic locations suitable for cultivating various food crops such as: fruits, vegetables, food grains etc. Globally, organic farming is cultivated in an area of 57.80 million ha. However, India accounts for just 2.59% of the area. The organic farming is followed in India in almost all the regions with three states Madhya Pradesh (34.34%), Maharashtra (13.19%) and Rajasthan (11.67%) accounting for about 59% of the total organic area of the country. The cultivated land under certification has substantially increased from 1.74 lakh ha in the year 2005-06 to 1.78 million ha in the year 2017-188 (https://www.researchgate. net/publication/338209816_Impact_of_farmer_producer_organization_on_ organic_chilli_production_in_Telangana_India) Agriculture and its allied sectors are the largest source of livelihoods in India. However, India still has many growing concerns. As the Indian economy has diversified and grown, agriculture’s contribution to GDP has steadily declined from 1951 to 2011. (Source: http://www.fao.org/india/fao-in-india/india-at-a-glance/). One of the main reasons is due to the lack of competence in Indian farmers for selling the crop in remunerative prices in the market. Some of the critical constraints and bottlenecks are lack of infrastructure for storage, transportation, quality control, packaging, price risk management, cool chains, market led extension, and framework for promotion of contract farming (Gohain, 2018). Realizing these issues Government of India under the Department of Agriculture and Cooperation identified Farmer Producer Organization (FPO) as the most appropriate institutional form to mobilize farmers and build their capacity to collectively leverage their production and marketing strength(Ministry of Agriculture, 2013).For analyzing the potential, importance and contribution of FPO in the agriculture sector, the present study aims to discuss the role of FPO in uplifting small and marginal farmers and its impact on the basis of the project undertaken by Silgur Bizat SwayattSahkarita FPO in Dehradun district of Uttarakhand.

Introduction

India has been advancing excessively in terms of workforce engagement as a lot of women have started seeking space in the business arena. The new age has given way to a new trend of entrepreneurshipwhich is flourishing without the quantification of gender. Needless to say, India has been dealing with a very bad history of patriarchal class arrogance and work division that cannot fully provide all the freedom to women who want to prosper in their professional lives.

The female entrepreneurs have to undergo a lot of obstacles right from the initiation of the idea till the plan operates. Sometimes, the existence as a women itself comes with a baggage of responsibilities. Indian women are bound to fulfill their responsibilities towards their family, community and work, balancing everything equally and in an efficient manner.

The conventionalism, ethnicity, social and cultural principles, parenthood, the tag of feeblest sex and insecurity curb the confidence of women in comparison to their male counterparts. Even though there have been considerable changes found in the women dwelling in urban areas, the rural women still have numerous hindrances blocking their path. The perceptive of the opponent sex is irrational in rural areas due to the lack of education and it becomes hard for the women to resist men in such cases.

The Indian customary draws a thin line between the capability and responsibility allotted to different gendersMohsen B., and Zouari S. (2014). It has even threatened the employment chances of females in the traditional and eccentric sphere of fiscal exercises. The present scenario has not broken the undeterred confidence of women who sought to make a career in business, since the last decade. With the alteration in technology, globalization and rivalry accentuation has made the operation of business more multifaceted and vibrant.

Organizational communication can be defined as the process of the flow (Transmission and Reception) of goal oriented messages between sources, in a pattern and through a medium or media. And organizational communication is the study of how people communicate within an organizational context, or the influence of, or interaction with organizational structures in communicating / organizing.

An additional elements in organizational communication (not present in interpersonal communication) is the flow pattern of messages. Thus here are 6 elements in organizational communication.

1. The transmitting source

2. The receiving source

3. Source (the target)

4. The transmitted message

5. The goal of the message

6. The medium or media and the flow pattern (which is called network). The transmitting and receiving sources are the people sending and receiving the message.

In Individual Contact Method, the extension agent engages with individuals on a one-on-one basis, ensuring personalized interaction with each person. This method is employed when the target audience is limited in number, geographically proximate to the communicator, and ample time is allocated for effective communication.

Farm and Home Visit

This method entails direct, face-to-face interactions between extension agents and farmers, typically conducted either on the farm or at the farmer's residence. Its objectives include providing firsthand information on agricultural and household matters, assisting farmers in problem-solving, and aiding in their livelihood sustainability.

Techniques

• Planning and Preparation:

• Identify target audience and topics of discussion.

• Gather relevant materials and publications.

• Schedule visits efficiently and provide advance notice to farmers.

The digital revolution has brought profound changes to numerous industries, and agriculture is no exception. Cyber Extension, which leverages Information and Communication Technologies (ICTs), plays a pivotal role in providing extension services and disseminating vital agricultural information to farmers. This discussion will explore the intricacies of Cyber Extension, highlighting its significance, applications, and impact on modern agricultural practices.

Transformation of Extension Services

• Traditional extension services relied on direct interactions between extension agents and farmers. While these face-to-face meetings were effective, they often struggled with challenges such as limited reach, high operational costs, and scalability issues.

• The introduction of ICTs has revolutionized extension services, giving rise to the concept of Cyber Extension.

Core Elements of Cyber Extension

• Digital Platforms: Cyber Extension leverages a variety of digital platforms, including websites, mobile apps, social media, and online forums, to share agricultural knowledge and engage with farmers.

• Remote Sensing and GIS: Advanced technologies like remote sensing and Geographic Information Systems (GIS) provide farmers with real time information on weather conditions, soil moisture levels, crop health, and pest infestations.

• ICT Devices: Devices such as mobile phones and tablets allow farmers to access extension services, receive advisory messages, and join virtual training sessions from any location at any time.

• Mobile Technology: Mobile phones and text messaging services deliver crucial information directly to farmers, including advisory messages, weather alerts, market prices, and other pertinent updates.

• E-Learning: Cyber Extension supports e-learning through modules, webinars, and online courses, educating farmers on best practices, crop management techniques, and market trends.

• Decision Support Systems: Tools and expert systems assist farmers in making informed choices regarding crop selection, irrigation schedules, fertilizer use, and pest management strategies.

Research methodology is a detailed plan of investigation and the blue print of procedure for carrying out the research. In this chapter, discussion on the methodology has been made to understand the concepts, methods and techniques, which are utilized to design the study, collect information, analyzing data and interpreting the findings for revelation of truth and formulation of theories. The entire chapter has been broken up under following sub-heads for easy understanding:

1. Locale of research

2. Sampling design

3. Pilot study

4. Variables and their measurements

5. Methods of data collection

6. Statistical tools used for analysis of data

Locale of Research

The present study has been conducted in a INDIA-BANGLADESH cross border village named Radhikapur in the state West Bengal. Villages from Kaliyaganj block in Uttar Dinajpur District.

The characters and the factors under study have been well discernible to this area

• The researcher’s close familiarity with respect to area, people, officials and local dialects

• The highly cooperative and responsive respondents

• The profuse scope to get relevant information regarding entrepreneurship communication behavior, economical communication, information seeking & responding behavior, information flow in & flow out etc.

• The locale is located at the terminal point & beside the INDIA BANGLADESH border, so there is some cross border impact also.

In any social science research, it is hardly possible to conceptualize and perceive the data and interpret the data more accurately until and unless a clear understanding of the characteristics in the area and attitude or the behavior of people is at commend of the interpreter who intends to unveil an understanding of the implication and behavioral complexes of the individual who live in the area under reference and form a representative part of the larger community. The socio-demographic background of the local people in a rural setting has been critically administered in this section. A research setting is a surrounding in which input and elements of research are contextually imbibed, interactive and mutually contributive to the system performance. Research setting is immensely important in the sense because it is characterizing and influencing the interplays of different factors and components.

The physical, social, or experimental context in which research is carried out is referred to as the research setting. This context must be accurately described in a study publication because it may have a significant impact on the findings and how they are interpreted. For instance, in a paper describing the social behavior of chimpanzees, the authors may need to provide the following information about the research environment: where the chimpanzees were observed (in the wild or in captivity), the number of chimpanzees observed, and whether they belonged to the same social group, the geographic location, the time of study, the season/weather conditions, the availability of resources like food/water/shelter, and the presence of environmental factor.

Introduction

Gender is a topic that cuts across all subjects and should be considered. The generational dimensions of rural and agricultural growth, whether we’re talking about kids, teenagers, or the elderly, have also grown in importance in recent years. Therefore, it is not surprising that a specific focus should be given on the issues of gender and youth and their relevance to the growth of agriculture. However, it is our custom to start with a few points to lay a foundation of thoughts. Nations Like India where majority of farmers practise subsistence agriculture, rural development is the cornerstone of agricultural development. According to the type of the problem in each country, an assessment of the present global response to the food crisis has indicated that various strategies are being implemented with varying degrees of success and failure. Different tactics are being used to shield the underprivileged from the rise in price shocks. Investment in the agricultural sector is consequently important for rural development and a rise in agricultural output. The contribution of women is also essential to the overall success of initiatives aimed at rural development to boost agricultural production in India. In sub-Saharan Africa, Women engage in more agricultural work than men do and supply the bulk of the labour for a variety of agricultural tasks. Women make up around 90% of the workers directly involved in producing arable crops (Ogunlela and Aisha, 2009). Therefore, rural development will occur when different pertinent institutions are given attention, including cooperative societies, the system of land tenure, banks and credit, the creation of sustainable local governments, educational institutions, medical institutions, and agricultural marketing outlets.

Introduction

Krishi Vigyan Kendras (KVKs) have marked their presence across India by executing various scientific as well as institutional reforms for the agrarian mass of our country. Right from its beginning in 1970s, farmers were actively trained for adopting different innovative tools and methods and were also provided with proper assistance in implementing them. The farmers were adapted to technical know-how of an introduced technology and produced significant results in the real f ield conditions.

KVKs provided proper training programmes on need-based curriculum in order to cater to the local and regional needs. This has also led to need assessment of various training needs and efficacies to make improvement in policies and future interventions. KVK can be instrumental in nurturing the process of gender empowerment by inviting and involving the farm women in the process of technological adaptation, adoption and socialization. There are methodological innovations as to how we can involve the farm women by employing and applying gender-sensitive KVK technologies as suitable for their job environment and climate. Especially in areas of value addition, rural crafts, women crafts, f ishery, horticulture and micro-finance, their roles are becoming more prominent and decisive. This is positive achievement in making them free from gender discrimination and impoverishment.

The knowledge score gained by respondents after training was more satisfactory in all aspects (58.33% had medium and 48.67% had high level of knowledge). The socio-economic factors of the participants viz. Education level played a significant positive role on the knowledge gain of the participants. (Upamanya et.al., 2020) Most of the farmers, i.e., 66.67 per cent with theoretical knowledge suggested that more field visits can be arranged, 63.33 per cent of the respondents suggested the training should be conducted in their own villages because the farm women cannot able to come to KVK by leaving their children and their regular household work and around sixty per cent (60.83 per cent) of the respondents suggested that organizing continuous and frequent training programmes for effective participation and retention of knowledge. (Chakkaravarthy and Balakrishnan, 2020)

In a country like India where the economy is dominant by agriculture and its allied sectors, nearly 75% of women are engaged in agriculture in comparison with their male counterparts. Among rural female workers, 50% comprises of agricultural laborer and 37% are cultivators. Not only this, around 70% of total farm work is performed by women folk. Majority of agricultural works are done by women farmers (FAO, 2011) and thus empowering them will have far-reaching effect on agricultural development. They usually operate multiple livelihood f ields, including farming, animal husbandry, and marketing along with doing the household chores and are closely involved in social issues. Among these activities when we look specifically into the agricultural tasks, it is very clear that approximately 70–80% of women are participating in all agriculture activities from raising seedlings, weeding, harvesting and, processing and value addition activities and sometimes their involvement extends to marketing their product. To compete in this fast-growing industry with others, the rural women need to be up-to-date with new technologies to foster the reach of innovations to the farm women. Training is one of the most important means by which farmers and rural women can upgrade their professional and technical skillset. This is an essential component in the area of agriculture where technology is changing day by day and the knowledge of the farming community including women needs to be upgraded at a comparatively quicker pace.

1. Introduction

Over the years, Agriculture Extension has been at the fore front within the delivery of adequate data to the farming community not just for increasing productivity however additionally to reinforce their standard of living. Keeping in-sight of the demand for agricultural growth, evolutionary modifications had been made in transfer of technology to succeed in the farming community effectively. The Information and Communication Technology (ICT) is one among the required counterparts which made the agriculture extension more realistic and quite interesting.

Developing nations like India are though capable to get self-sufficiency in food production after green revolution however they’re in risk to keep this self sufficiency as they are possibly to face food shortage in near future due to rapid population growth. Thus, the demand of continuous increasing population is often fulfilled with the assistance of ICT as a tool of revamping extension network of the country. ICT is an emerging tool for development of farming communities.

Information and communication technologies have unique feature that provide opportunities to harness them in ways which are extraordinary from traditional media. ICT provides two-way communication between rural communities and development organizations. ICTs also improves the capacity to look for information and increase the number of information available, provide quality information, reduces uncertainty and enhance market participation.

Introduction

The concept of communication for development emerged with the Modernization theory, which developed its roots after World War II. Wilbur Schramm and Daniel Lerner, the two major proponents of this theory opined that the major obstacle to development was the psychology of the undeveloped citizens. The communication models under modernization paradigm observed communication process as the transfer of message from sender to receiver (Lasswell, 1948). It was found that communication theories like two step-flow, diffusion theory, or the early extension approaches were quite harmonious with the top-down modernization theory. After the Modernization paradigm, an another theory of communication for development emerged named as Dependency theory. Dependency theorist like Jean Servaes (1996) criticized the broadcasting and other mass-media systems as they tended to support modernization and were anti-development; also they were inclined to promote the political agenda. Solution to underdevelopment of third world countries require major changes in media structure that were dominated by commercial principles & foreign interests into media structures which are self-reliant and community oriented (Servaes, 2002). In 1970s scholars such as Paulo Freire and Nora C. Quebral started pleading in favour of bottom up development theories which led to evolution of a new development paradigm called the multiplicity paradigm. This paradigm conceptualised the basic idea that development is integral, multidimensional and dialectic process which can differ from one society to another (Okigbo and Eribo, 2004). Multiplicity paradigm led to emergence of a new form of communication called participatory communication.

Introduction

India is an agriculture-based country and it contributes most to the economy of the country. Different types of crops are cultivated in a wide range in different ecological regions based on different seasons. So, crop residue is also generated in an extended way by cultivation (Devi et. al 2017). Crop residue is the left over part of the crop after harvesting. In India, crop residue generates around 600 Mt and from which cereals are 70%, fibres 13%, oilseeds 6%, pulses 3%, sugarcane 2%, and others 6% (Jain et al., 2014). Corn production has increased more than 15 times from 1950-51 to 2016-2017. Rice, wheat, millet, barley, and maize are important cereal crops in Uttar Pradesh (Roy and Ahmad, 2015). Traditionally, Crop residue was used as cattle feed, animal bedding, cooking fuel, organic manure, etc. and some residues were used in making handicraft products by rural women. but still, a huge amount of residue is left without management and farmers have no option left except to burn it. About 90 to 140 Mt of crop residue burning in the field or households as fuels (Jain et al., 2014). In the process of harvesting and threshing, residues are left behind in the f ield. Farmers need to clear their fields early for the planting of the next crop so they do have not enough time and it is tough to clear the field at that time. Therefore, the farmers opt for the burning of residue in harvested fields due to a lack of access to user-friendly, cost- and time-effective options. The burning of crop residue creates many issues and effects on the environment and health badly. In a report of NAAS in 2017, it was estimated that in November 2016 at the period of rice residue burning, the NASA satellite images showed the intensity of rice residue burning in Punjab, Haryana, Western Uttar Pradesh, and Uttarakhand was very high. It is doing an additional job of increasing air pollution with vehicles, chimneys, industries, etc. Crop residues release many gases by burning them and these gases are contributing to global warming.

Introduction

Self Help Group is a voluntary and self managed group of poor people, who come together to promote savings among themselves and pool savings for activities benefiting either individuals or communities economically. Empowerment of women has now become a key issue in the Government’s Five year plans by organizing women into Self Help Groups to make the beginning of a major process of empowering women. 320 million people, out of our 1.1 billion, are steeped in abject poverty and due to their asset lessens it is difficult for them to access any kind of aid from banking / financial institutions and this state of the hopelessness and the constraints of an ineffective credit delivery system can be transcended by enhancing the self esteem and raising the feeling of human self worth. The SHGs approach is a reshaping initiative that enhances the livelihoods and ensures sustainability by enabling poor families to access effective economical and social development leading to empowerment.

In Tripura SHG’s has been introduced in the year 1999.The main objectives of this programme by mutual beneficial of social and economic activities through women mobilization. SHG’s are a way to involve rural women and men actively in the development process by means of increased income Agricultural situation of WTD differs to some extent from the other districts in regard to topography, soil, extent of rain-fall, variation in temperature and humidity which has resulted in difference in cropping pattern also from that of the other three districts. People mainly practice rice and vegetables cultivation. The plain land people also were satisfied to grow single crop preferably paddy without having any knowledge and experience of improved cultivation for growing multiple crops. Animal husbandry is another sector contributing to the economy of WTD. Cattle and poultry are the main livestock wealth of the district. (DRDA office, Agartala, 2010). Many Government and non-government organization now have come forward for helping poor communities and to energize their capacity in development activities of which Self Help Group (SHGs) is thought as the best means for improving their position in the society.

Introduction

Innovation as a new idea, method, or object may be developed by research or by a farmer. Diffusion is a special type of communication on innovations. The proper use of innovation is called adoption. Communication is different from diffusion in the sense that communication covers all types of messages whereas diffusion is concerned with a message of new ideas. The extension workers need to understand the meaning of diffusion, adoption processes, innovation, etc. by which farmers accept new ideas. Adoption is a sequence of thoughts and actions which an individual goes through before s/he finally adopts a new idea. The adoption process is a mental process for passing the new idea to final adoption. In the diffusion process, the new idea spreads from its source of invention or creation to its ultimate users or adopters. Perception is an activity through which an individual becomes aware of objects around oneself and of events taking place.

Elements in the Diffusion of Innovations

The four main elements in the diffusion of innovations are innovation, communication channels, time, and social systems.

The Innovation

Innovation is a new idea expressed in terms of knowledge, persuasion of decision for adoption. The perceived attributes of innovations are relative advantage, compatibility, complexity, trialability, and observability.

Relative advantage: The innovation should have a relative advantage over the existing ideas in terms of economic and social-prestige factors, convenience, and satisfaction. The advantage can be influenced by providing various incentives.

Compatibility: The innovation should be compatible with the socio-cultural values and beliefs of people.

Introduction

In the face of a growing global population and increasing pressures on natural resources, the quest for sustainable and efficient agricultural practices has become highly significant. The integration of livestock with cropping systems and grasslands stands out as a holistic approach that not only addresses these pressing challenges but also unlocks a myriad of economic benefits. This chapter delves into the profound significance of integrating livestock with cropping systems and grasslands in modern agriculture, exploring how this synergistic combination enhances resource utilization, promotes resilience, and fosters a thriving agricultural sector.

The roots of integrated farming practices can be traced back to ancient agricultural traditions, where farmers instinctively recognized the advantages of combining crop cultivation and animal husbandry (Devendra and Thomas, 2002). Over time, this integrated approach evolved and adapted to different cultural and geographical contexts. In traditional mixed farming systems, livestock provided essential services such as draft power (Gomiero et al., 2011), manure for fertilization, and protein-rich food. As agriculture progressed with technological advancements, there was a shift toward specialized monoculture and intensive livestock farming (Herrero et al., 2013). However, the unintended consequences of these systems, including soil degradation, environmental pollution, and declining rural livelihoods, paved the way for a resurgence of interest in integrated farming methods (FAO, 2020).

Introduction

To accomplish experimentations in laboratories, sometimes we need microscope to test/validate our ideas/findings. A microscope is needed to examine objects which are very small which cannot be visualised by naked eyes. However, microscopic study requires some expertise in operating the microscope, particularly the sophisticated microscopes, as well as to prepare (peeling, sections, cutting, fixation, staining, dehydration, mounting, etc.) the sample, so that it can be appropriately examined for the anticipated details.

According to the scientific requirements different types of microscopes are used in the laboratories for research purpose. In this chapter, our aim is to acquaint you with the basics of using and handling of microscopes, particularly a compound microscope that is commonly used by the graduate and post graduate students for basic research.

Microscopy is often designated as the scientific investigation that is employed to review and analyse minute structures and objects using a microscope. The term “microscope” has been derived from ancient Greek words “micros” meaning “small” and “skopeîn” meaning “to look at or see,”.

Microscope

A microscope is a laboratory instrument used to examine objects (biological specimens) which are too small to be seen by the naked eye. The microscope must accomplish three tasks:

• Magnification- to provide a magnified image of the specimen.

• Resolution- to separate the details in the image.

• Contrast- to render the details clearly visible to the eyes.

Although we will tnroduce to you the different types of microscopes used for different speciments, our main focus is to discuss about compound microscope, which is commonly used in the laboratories. Compound microscope was developed around the beginning of 17th century.

Introduction

Test of pollen viability (extent of pollen viability) is important in pollination experiments to ensure fertility/seed setting. It is also important in monitoring state of pollens during storage in ecological/ taxonomic studies as well as during research on pollen biochemistry, genetics, stigma interactions, and incompatibility studies. Pollen viability refers to the ability of pollen to accomplish post-pollination events to achieve fertilization. Pollen viability test has gained importance particularly in plant breeding and hybrid seed production experiments/ practices. In this chapter, you will be acquainted with the basics of pollen viability test. However, for more professional knowledge on the topic readers are suggested to refer specialized books.

Pollen Viability Test

It is important to know the extent of viability of pollens used in pollination experiment, in finding fertility of a plant of interest, to monitor state of pollen on storage, in ecological/taxonomic studies, as well as in research on biochemistry, genetics, stigma interaction, incompatibility assay, etc. of pollen. Several pollen viability tests have been developed time-to-time. It is recommended to initially use different tests for a given pollen type to find out the most appropriate method that provides reliable result on pollen viability. It is important to note that every procedure requires standardization of protocol according to the sample used. Following different tests are used for assessing pollen viability.

1. In-vitro Pollen Germination Test

It is a simple, speedy, and quantitative test for assessing pollen viability. In this method, a collection/sample of pollen is germinated in vitro and observed under microscope. The percentage of germinating pollens (producing pollen tube) after appropriate treatment and a given period of time is determined. The percentage provides an index of viability of the pollen sample.

Globally, antimicrobial resistance (AMR) is an important public health and development threat (WHO, 2020). Being one of the top 10 global public health threats, the ever-increasing rates in the occurrence of drug-resistant bacterial infections have become a grave public health concern for the governments (Laxminarayan et al., 2013). Moreover, such infections would be difficult to treat and therefore can lead to worse clinical outcomes (Laxminarayan et al., 2013). Worldwide, each year about 700,000 people die from antimicrobial resistant infections and the mortality figures are projected to reach 10 million/ year by 2050 (O’Neill, 2016). The crude infectious disease mortality rate in India is more than 400 per 100,000 persons and at least 23,000 deaths in adults and 58,000 neonatal deaths per year are caused by AMR bacteria (Laxminarayan and Chaudhury, 2016). A 2017 estimate puts the cost of developing an antibiotic at around US$1.5 billion (Towse, et al. 2017). Meanwhile, industry analysts estimate that the average revenue generated from an antibiotic’s sale is roughly $46 million per year. “That’s tiny and nowhere near the.

Microbial Resistance Mechanism

Huge use of antibiotics in nosocomical environment has lead to the occurrence of multidrug resistance mechanism by microorganism against particular antibiotics (Munita et al., 2016; Zhao et al., 2020). Main operation includes chemical modification, efflux pump through passivation, modification of drug targeting gene and systemic elimination of antibiotics as many of them can form biofilm (Rajput et al., 2018) which can show extreme resistance. Chemical and enzymatic mechanism can include inactivation, activity loss, degradation and derivatizaton of antibiotics chemical group (Liu et al., 2019). Best idea may include production of enzymes or they can also expel antibiotic to efflux pump. Antibiotics drug efflux resistance can be accomplished by drug efflux pump playing an important role in microbial resistance. A different type of efflux pump system has been identified that include lipophilic and hydrophilic efflux system targeting the drug at different chemical properties (Wasaznik et al., 2009; Kumar et al., 2012). Another strategy adopting in resistance mechanism is modification of drug targeting gene. This mechanism makes the changes in drug to lose its target through drug targeting gene modification. Another important resistance mechanism is effectiveness of antibiotics by interfering with the target site. Therefore, bacteria has evolved different mechanism that include target site protection. A bactericidal role played by beta lactum antibiotics in inhibition of mucopeptide synthase and bacterial penicillin binding protein (PBP) in cell wall transpeptidation reaction that prevents the formation of complete call wall and hence dies (Sauvage et al., 2016). Bacteria also developed its own strategies to cope up with the environmental stress that can also include human body. In course of gaining the advantage bacteria needs to compete for nutrients and to keep away from the molecules produced by other competing organism (Zhao et al., 2019). Recently researchers have found the importance of biofilm resistance in bacteria. Bacterial biofilm resistance produce by complex and systematic drug resistance mechanism.

Introduction

Antibiotic-resistant bacteria are a major cause of health care-associated infections around the world, and resistance has also emerged in infections in the wider community. Infections caused by multi resistant organisms significantly increase morbidity, mortality, and health care costs. Molecular analyses have revealed that widespread multi resistance has commonly been achieved by the acquisition of preexisting determinants followed by amplification in response to selection. The capture, accumulation, and dissemination of resistance genes are largely due to the actions of mobile genetic elements (MGE), a term used to refer to elements that promote intracellular DNA mobility (e.g., from the chromosome to a plasmid or between plasmids) as well as those that enable intercellular DNA mobility.

Insertion sequences (IS) and transposons (Tn) are discrete DNA segments that areable to move themselves (and associated resistance genes) almost randomly to newlocations in the same or different DNA molecules within a single cell. Other elements, such as integrons (In), use site-specific recombination to move resistance genes between defined sites. As these types of MGE are often present in multiple copies indifferent locations in a genome, they can also facilitate homologous recombination(exchange of sequences between identical or related segments). Intercellular mechanisms of genetic exchange include conjugation/mobilization (mediated by plasmidsand integrative conjugative elements [ICE]), transduction (mediated by bacteriophages), and transformation (uptake of extracellular DNA). Interactions between thevarious types of MGE underpin the rapid evolution of diverse multi resistant pathogens in the face of antimicrobial chemotherapy. Primarily the most important and/ or topical elements in Gram-negative and Gram-positive bacterial species of particular concern clinically, namely, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. (the so-called ESKAPE group) (Rice LB., 2008) as well as Escherichia coli (giving the ESKAPEE group) (Llaca-Díaz J.M. et al.,2012); nonetheless, many of the MGE types described are of course broadly relevant to many other bacterial taxa.

Introduction

Women in India constitute nearly half of the population. They contribute 75% to the development of our society as compared to men who only 25%. According to the census 2011, nearly 98 million women in India have agriculture jobs, but around 66.1 million of them are depended on others’ farms as agriculture labours. They are engaged largely in cotton, tea, oil seeds and vegetable production. It is also worth mentioning that from the basic level of work concerning farm related activities to unskilled farm jobs like sowing, transplanting, weeding, harvesting and post harvesting activities like winnowing, processing, storage etc. women are engaged right from the start.

Woman’s contribution to the fisheries sector is 22% according to the FAO. Food security, horticulture, sericulture, livestock production and collection of non- timber forest are some of the allied sectors in which they are involved. They are also involved in other allied sectors which include cattle management, milk and poultry farming, and fodder collection. At the same time, women’s domestic activities include cooking, child rearing water collection from the nearby and far-off places, fuel wood gathering and the overall upkeep of household. Ironically, women face disparities in terms of compensation, their share in properties and in representation in local bodies. Much of their contribution in the food production system as food producers and providers has not received effective recognition. This affects their lives and familial conditions in terms of poor health of children and low educational attainments.

3.1 Introduction

Groundwater constitutes about 89% of the total fresh water resources in the planet. But in recent years, due to over exploitation of ground water and erratic nature of monsoon, there has been depletion of ground water across the world. Depletion of ground water has reached to the extent that it is virtually impossible to get the water table back. Even though there is a possibility of recharge of water from the other areas, the process is very slow and may take one year to replenish one meter. In view of this management of ground water has become one of the most significant issues in recent times. Added to it, there are also environmental problems such as aqua for mining, salt water intrusion, stream base flow reduction etc. For several reasons the efficient management of ground water resources through market mechanism has become difficult. Against this context the present article attempts to analyze the need for sustainable ground water management in India. The article also briefly discusses the concept of sustainable ground water management, factors affecting ground water availability, different approaches towards developing and using available ground water without adversely affecting the hydro geological balance. Further, the paper highlights strategies for sustainable groundwater management, including development of aquifers, rainwater harvesting and artificial recharge methods. The article offers some relevant policy recommendations for sustainable groundwater management in India.

Introduction

Rising temperature, decreasing precipitation, increased frequency in drought and flooding, etc. is making us realize climate change is not some cooked up story. Still there are people who believes climate change is not real. By definition, Climate change is a long-term shift in global or regional climate patterns. This will affect the life of people in many forms: health, food, water, etc. (Table 1). Agriculture is a highly vulnerable field to such weather and climate changes, they can have significant direct and indirect impacts on farm productivity and profitability. Climate change will have adverse effect on crop physiology, growth and chemistry and thus it will cause negative impact on agricultural production. Because of the variation in climate, moisture availability may change, which limits vegetation activity/plant growth, increase in drought/ heat/flooding will the crop growth and yield. Elevated CO2 does not have a profound effect on C4 plants. On the contrary, tissue nitrogen concentrations are higher for C3 species under increased CO2 . Intergovernmental Panel on Climate Change (IPCC) estimates that climate change and elevated CO2 is expected to increase competitiveness of invasive weed. IPCC also estimates that with 1°C rise in global temperature, 5 to 10 per cent yield reduction of major food and cash crops (Pachauri et al., 2014).

Introduction

Climate change is widely acknowledged as the most significant contemporary challenge facing humanity. According to a recent report from the Intergovernmental Panel on Climate Change (IPCC, 2022), the situation has deteriorated further, with 3.3 billion people worldwide highly susceptible to climate change. Current unsustainable development practices are escalating the exposure of ecosystems and populations to climate-related risks. Human activities and their impact on the climate and environment are leading to unprecedented extinctions of animals and plants, resulting in a loss of biodiversity and posing a threat to life on Earth. The diversity of microorganisms is fundamental to maintaining a healthy global ecosystem, as the microbial world serves as the life support system of the biosphere. Although the influence of human activities on microorganisms is less conspicuous and less well understood, a significant concern is that changes in microbial biodiversity and functions will impact the resilience of other organisms, affecting their ability to adapt to climate change. Microorganisms play crucial roles in carbon and nutrient cycling, as well as in the health of animals (including humans), plants, agriculture, and the global food web. Microorganisms inhabit all environments on Earth occupied by larger organisms and are the exclusive life forms in certain environments such as the deep subsurface and extreme habitats. Dating back to the origin of life on Earth at least 3.8 billion years ago, microorganisms are likely to persist well beyond any future extinction events. Despite their vital role in regulating climate change, microorganisms are seldom the focal point of climate change studies and are typically overlooked in policy development. The challenge lies in understanding their intricate role in the ecosystem due to their vast diversity and varied responses to environmental changes.

Introduction

Climate change may advance more rapidly than anticipated, introducing novel environmental conditions for cultivating horticultural crops. The rise in atmospheric CO2 levels from non-renewable energy sources combustion drives global average temperatures, altering weather patterns worldwide with regional variations (Stocker et al., 2013). Currently, certain regions are already experiencing the effects of extreme weather events such as heat waves or frost, while prolonged droughts pose a growing threat to global food security elsewhere. Climate changes may yield both positive and negative outcomes, but they will undoubtedly alter production conditions and product quality (Kaufmann and Blanke, 2017).

Elevated temperatures can enhance the ability of air to hold water vapor, leading to increased water demand. This process can elevate evapotranspiration rates, potentially depleting soil water reserves and causing water stress in plants during dry periods. Fruit production is particularly vulnerable to water stress, especially in regions where trees lack irrigation. Numerous studies indicate that water stress diminishes crop yields and hastens fruit ripening (Henson, 2008).

Introduction

The term ‘Fish Marketing’ is composed of two broad meaning term ‘Fish’ and ‘Marketing’. Before discussing the methodological issues of fish marketing data analysis, we must understand the broader meaning of it as both words are being used frequently with a précised meaning. Google dictionary explains fish as ‘A limbless cold-blooded vertebrate animal with gills and fins living wholly in water’. But ‘fish’ as a component of fish marketing or social science study, means a product and a variety of product, which has different time, space and form utilities for consumers.

The word ‘marketing’ is not merely buying and selling of fish, rather it connotes a series of activities involved in moving goods or services from point of production to the point of consumption. So ‘fish marketing’ is defined as physical and institutional set up to perform all activities involved in the flow of fish, fish products and services from the point of initial fish production until they are in the hands of ultimate customers.

It includes assembling, handling, storage, transport, processing, wholesaling, retailing and export of fish and fishery products as well as accompanying supporting services such as market information, establishment of grades and standards, community trade, financing and price risk management and the institutions involved in performing the above functions.

It is desired to have an efficient and well planned distribution networkso that fish and fishery products move from the place of landing or production to the place of consumption at cheapest cost with quality –intact, ensuring the maximum price realization to the farmers or fish producers. It is really challenging to the public agencies involved to meet the requirements of all three major players, viz., fishermen or fish farmers, consumers and traders.

It includes all activities involved in creation of time, place, form and possession utility. Philip Kotler explained marketing as the science and art of exploring, creating, and delivering value to satisfy the needs of a target market at a profit. ‘Fish marketing’ is different from marketing of other goods and services and even differs a bit from marketing of variousagricultural goods and services.

Introduction

The Aquaculture and fisheries sector in India is a multi-disciplinary sector that provides food security, employment, economic gains, and socio-economic upliftment for those involved in fish exploitation, production, and processing. Sustainable fishing practices, improvements in fish breeding and husbandry technologies, along with the introduction of new species, have helped increase production levels through small-scale rural aquaculture, largely through governmental and non-government organizations.1Aquaculture and f isheries entrepreneurship are crucial for youth economic empowerment in India, providing and promoting sustainable development and employment opportunities within the fisheries sector. Technological advancements in aquaculture can enhance productivity, optimize resource utilization, minimize environmental impacts, and improve profitability. Aquaculture and fisheries entrepreneurship can promote environmental sustainability by adopting eco friendly practices and establishing strong market linkages. It has significant potential in rural areas where employment opportunities are limited, reducing migration and contributing to local economic growth. Government initiatives and policies that promote entrepreneurship, youth development, and sustainable fisheries are instrumental in supporting young individuals interested in aquaculture.

Fisheries and aquaculture sector is highly diverse (Figure 1) and an important source of livelihood for about 28 million fishers and fish farmers in the country. India is the 3rd largest fish producing country with about 8% of global fish production. Globally, India stands 2nd in aquaculture production and is one of the top shrimp-producing and seafood-exporting nations. The fisheries sector in India has shown a sustained annual average growth rate of 8.61% for the 8-year period from 2014–15 to 2021–22 (at constant prices). The sector has reached a record fish production of 162.48 lakh tonnes in FY 2021–22 and has immense potential for growth.

Introduction

Dried fish is a staple food for various communities and considered a ‘hidden’ sub-sector within small-scale fisheries. Dried fish defined broadly as aquatic animals preserved using simple techniques such as sun-drying, salting, fermentation, and smoking that permit storage as foods at ambient temperature for extended periods without specialized packaging (Belton et al., 2022). The nutritional quality of dried fish remains intact, sometimes retains higher quality standards compared to fresh fish (Faruque et al., 2012). Fish drying is an age old practice followed for preservation of fish. Over the years, it has grown from a subsistence occupation to a full flourishing business (Sanjeev et al., 2020). This traditional method is followed for the preservation of fish especially in rural areas (Chakrabarti and Varma, 1999). Drying method is considered as the least expensive method of fish preservation (Balachandran, 2001). Dried f ish attracts greater demand during fishing ban period or lean seasons, as the fresh fish availability is relatively low (Das et al., 2013). Dry fishes are used as food and the deteriorated Dried fish business can play an important role in the national economy in multiple ways including minimizing post-harvest losses of fish providing a source of animal protein, enlarging livelihoods, utilizing idling labor into the production process and as a dish, especially for rural poor (Wickrama et al., 2021). Dry fish marketing chain begins with a farmer (dry fish producer) and concludes with the final consumer with several intermediaries in between. These marketing middlemen provide services for producing, assembling, loading, packaging and transporting dry fish, resulting in cost increase at every stage of marketing processing (Mallick et al., 2022). Dried f ish are usually low in price, easily divisible and can be stored and transported for accessibility by the poorest and most vulnerable communities throughout the year. Dried fish can therefore play a vital role in nutrition security. In India, dry fishes are widely sold at local markets and commercially important species are also exported to other countries (Immaculate et al., 2013). Dry fish are used for production of poultry/fish feed. Today, dried fish products business provide employment for millions of people, particularly women, who are the majority of the fish- drying workforce in many locations (Belton et al., 2022).

An Overview of Fish and Shellfish Health Management in Aquaculture in India

Aquaculture in India in particular freshwater fish culture comprised mainly of Indian major carp cultivation has a long history. Since 1980s commercial carp culture expanded, particularly in Andhra Pradesh and in few years became an Asia model. Then on, it is slowly and steadily expanding to different parts of the country particularly Punjab, Haryana, West Bengal, Orissa and Tamil Nadu and Karnataka. Of late, culture of Pungasius (Basa) has come up on large scale in AP. In addition, there is also growing small scale commercial cultivation of catfish, murrels, tilapia and freshwater prawn(Macrobrachium rosenbergii). Aquarium fish breeding is also expanding to establish itself as an industry in India.

Brackish water culture has been practiced traditionally in India in Pokkali fields of Kerala, Bheries of West Bengal and Ghaznis of Karnataka since hundreds of years. From 1990 onwards, commercial shrimp culture came into existence along the coasts of India. High export value, support from government and short culture period encouraged private entrepreneurs to pursue shrimp farming in a big way. There is vast potential for fish culture in brackish water and at the present efforts are on to popularize culture of Asian seabass, mullets, Eutroplus and milk fish. Mariculture is still at infancy but increasing at a slow and steady rate.

Aquaculture health management has to be viewed from the incidences and outbreak of diseases due to growth and expansion of the industry. Aquaculture has expanded tremendously in the last three decades, growing at 6-7 % annually. Contribution of fish production from aquaculture in the country is around 60 % compared to 10 % it was 40 years ago. In few years to come, aquaculture contribution may go up to 80 % of total fish production. Today 2.43 m ha of freshwater and 1.15 m ha of brackish water are under culture. In addition, 8.62 m. ha of irrigated inland area mainly in Haryana, Maharastra and Karnataka which have become saline and unsuitable for agriculture are slowly being reclaimed for aquaculture. Farmers are growing acclamatized saltwater fish and shrimp spp in inland saline waters and a shift like this may favour pathogens with different virulence to cause disease. Overall, it can be seen that in addition to increased conventional areas in fresh and brackish water, aquaculture is being practiced in unconventional areas like saline soils. Performance of fish and shellfish in these non conventional water bodies in the long run needs to be studied from their health point of view.

Diversity of gut microbial community

The human microbiota (the collection of microbes that live on and inside us) consists of about 100 trillion microbial cells that outnumber our ‘‘human’’ cells 10 to 1, and that provide a wide range of metabolic functions that we lack. It has been estimated that they encode 100-fold more unique genes than our own genome. Furthermore, the gut microbes contribute to energy harvest from food, and changes of gut microbiome may be associated with bowel diseases or obesity. To understand and exploit the impact of the gut microbes on human health and well-being it is necessary to decipher the content, diversity and functioning of the microbial gut community. If we consider ourselves as superior organisms encompassing these microbial symbionts, by far the majority of genes in the system are microbial. In this sense, completing the human genome also requires the characterization of the microbiome (the collection of genes in the microbiota).

Methods of counting viable and non-viable bacteria in gut

Before the advent of genome sequencing and genome-wide analysis method, our knowledge of molecular characteristics of diverse gut microbial population was extremely limited. To obtain an estimate of cultivability, microbial ecologists generally compare microscopic counts with total viable counts. The total viable count made on a nonselective agar based medium estimates the number of colony forming units (cfu) per gram of sample. The finding that total viable counts are typically lower than total microscopic counts was thought to be due to the number of dead cells. Indeed, dead bacteria in feces may constitute up to one third of the total bacterial community. However, recent nucleic acid based studies indicated that a majority of bacteria in a variety of ecosystems are different from those described in culture.

Cheese is made from milk, with the addition of cream, buttermilk, and/or whey. This basic raw material is also called cheese milk. Cheese consists mainly of casein (the major protein of milk), other milk proteins, fat, other milk components, and a certain percentage of water, which is bound. Proteins are precipitated by enzymes and/or acidification as well as heat and are separated by suitable processes from the aqueous phase. (whey, serum). Cheese is most often molded, pressed, and salted and has fungal and bacterial culture additions. colorants, herbs, spices, and other non-dairy ingredients are also added to the cheese. It is consumed either fresh or at different stages of ripening.

Worldwide, there are more than 2000 types of cheese, sometimes made by very different manufacturing processes. A classification can be based on several aspects and is done in different countries according to different criteria. A general classification can be made for three major groups:

a. Rennet or natural cheese: manufactured straight from milk by using proteolytic enzymes (rennet) and acid, with a more or less pronounced ripening process.

b. Fresh cheese or non-ripened Cheese: Quarg, fresh cheese, and white cheese are examples. Its manufacturing process is similar to that of rennet cheese manufacturing, but it has a high degree of acidity and is not subjected to a proteolytic ripening process.

c. Long-life cheese (processed cheese): it is more often made from rennet cheese and is textured by thermal treatment and made shelf-stable.

Clinical Symptoms

• Anchor worms can be seen with the naked eye

• Frequent rubbing or “flashing”

• Localised redness

• Inflammation on the body of the fish

• Tiny white-green or red worms in wounds

• Breathing difficulties

Ultrasonography is the process of obtaining images of an area, organ or tissue with the help of ultrasound beam that can be displayed on a screen. Such images can be recorded on videocassettes or printed on a thermal paper. Ultrasonography in veterinary practice is a revolutionary step for diagnosis of various ailments and to assess normal physiological functions of the body organs of domestic animals. Ultrasonography is considered a wonderful tool particularly for the study of reproductive functions viz. follicular dynamics, pregnancy diagnosis and abnormalities of contents of tubular tract. In 1980, Palmer and Driancourt reported for the first time, real time ultrasonography for diagnosis of pregnancy in the mare. This report generated considerable interest among veterinarians and scientists about ultrasonography and this new discovery contributed significantly towards understanding of functioning of the uterus and ovaries of mare (Chevalier and Palmer, 1982; Ginther, 1983; Ginther and Pierson, 1984a & 1984b), cows (Pierson and Ginther, 1988, Reeves et al., 1984) and other species (Buckrell, 1988; Driancourt, 1991). The ultrasonography is fast replacing the age-old procedure of rectal palpation of genital tract for pregnancy diagnosis (Pieterse et al., 1990). This technique has been used and advocated for the use in the academics and field practice.

The recent availability and use of ultrasonography in veterinary science has revolutionized the study of bovine reproduction. The information- gathering capabilities of this technology are much higher than those of conventional rectal palpation. Ultrasonic imaging has provided new insights into the complex biology of various reproductive processes such as folliculogenesis and early fetal development. With the pressure on agricultural land, due to ever increasing human population, the grazing grounds for animals are fast squeezing and as a result more and more animals are being stall-fed. This practice has adversely affected the availability of essential nutrients to the animals and their reproductive efficiency. The problem is graverin small states, where pressure on land is more to accommodate the expanding developmental and commercial activities of the national capital situated next door. The routine applications of ultrasonography include evaluation of animals for pregnancy, twinning, cyclic structures on ovaries, uterine and ovarian pathologies etc.

In Doppler imaging, the reflections are from circulatory vessels, while in 2D ultrasonic image the reflection is from a tissue(s) or organ(s) In 2D ultrasound strength of reflection in B-mode depends upon density of the organ.On other hand the reflection in Doppler imaging depends upon direction of the circulation. If circulaltion is coming towards transducer, the signal will be strong, while it looses its strength while flowing away from the transducer. As shown in the diagram, the position of transducer on curved surface decides the strength or amplitude of signal. If it is positioned on curve end from where circulation is coming, the signal will be of higher amplitude, but when position is changed to other end of curved surface, where circulation is going down the amplitude of signal will decrease accordingly and is shown in reverse direction.

Principle of Doppler

Movement of blood in vessels is detected, which is depicted by color in some ultrasound machines. The flow coming towards transducer is shown above baseline, while flow going down i.e. away from transducer is shown below baseline. If position of transducer is changed from where the arterial flow is going away from transducer then, the arterial flow will be shown below baseline and venous flow that is coming towards transducer will be shown above baseline. Some machine shows red and blue color of the flow. The red color shows flow coming towards and blue color shows flow going away from transcer. A beginner ultrasonographer may think that the red color is from artery and blue is from vein. This is not true, this shows direction of flow. Since ultrasonic image of flow in Doppler is formed from series of pulses returning from vessels, the magnitude of pulse changes with variation in flow. A stationary flow will not show any height of magnitude.

Real time ultrasonography provides means to directly image the reproductive tract. An extensive amount of information can be gained from even a single examination, including determination of ovarian (luteal or follicle detection) and uterine status, detection and monitoring of ovarian and uterine pathology, monitoring the post-partum mare, detection of twins, prediction of ovulation, fetal growth and development and determination of sex of fetus. When first introduced the use of ultrasonography was primarily limited to early pregnancy diagnosis only, with advancement of knowledge and interpretive skills, the diagnostic ultrasonography has a much more application in reproduction. Some of the applications are discussed in this lecture.

Procedure

The procedure and precautions for intrarectal ultrasonographic examination are similar to those for rectal palpation, and no additional restraint is required. The transducer should be protected by the examiner’s hand to prevent trauma to the rectal wall, and the transducer should be well-lubricated. Care should be taken to avoid fecal material attaching to the transducer. After evacuating fecal material from the rectum, the probe is introduced and moved across the reproductive tract in the following pattern: uterine body, right uterine horn, right ovary, right uterine horn, uterine body, left uterine horn, left ovary, left uterine horn, uterine body then cervix. Good contact must exist between the transducer and rectal wall. Air in the rectum or a gas or fluid-filled loop of bowel will result in a distorted image. To minimize scanning errors, principally those of omission, it is recommended to conduct the same scanning procedure during each examination.

Spontaneous contractions of the uterus are controlled and coordinated for various reproductive functions. The non-pregnant uterus facilitates ova and sperm transport, provides adequate embryo placement for implantation, and contributes to the expulsion of menstrual debris through increased contractility, or periods of relative quiescence (Hutchings et al., 2009). Uterine dysmotility has been implicated in the pathogenesis of certain infertilities, implantation failure, endometriosis, dysmenorrhea, and abnormal menstrual events (Kunz and Leyendecker, 2002; Aguilar and Mitchell, 2010). Although these conditions may not contribute to mortality but can significantly affect patient’s reproductive health, and considerably alter their quality of life (Jones et al., 2004; Weissman et al., 2004; Chachamovich et al., 2010). Dysmenorrhoea refers to the occurrence of painful cramps in the lower abdominal region during menstruation and is one of the unresolved gynecological disorders in adolescent girls and women of reproductive age (Wang et al., 2004; Harel, 2008). This condition is mainly characterized by cramping pain in the lower abdomen immediately before or during menstruation, which does affect the quality of their life and work (Davis and Westhoff, 2001).
