The world is facing unprecedented challenges in ensuring global food security, and climate change is exacerbating these challenges. Rising temperatures, changing precipitation patterns, and increased frequency of extreme weather events are altering the dynamics of crop diseases, making them more unpredictable and difficult to manage. The consequences are dire: crop diseases can lead to significant yield losses, reduced food quality, and economic hardship for farmers. Therefore, it is imperative that we develop and implement effective strategies for managing crop diseases in the face of climate change. Weather wisdom is a critical component of these strategies. By understanding and interpreting weather patterns and their impact on crop diseases, farmers can make informed decisions about crop management, disease monitoring, and control. This approach is essential for climate-smart agriculture (CSA), which aims to promote agricultural practices that can help farmers adapt to climate change while improving agricultural productivity and sustainability. By leveraging weather wisdom, farmers can reduce crop losses, improve food quality, and enhance their resilience to climate change. This book, “Weather Wisdom for Crop Disease Management: A Requisite for Climate-Smart Agriculture,” provides a comprehensive overview of the role of weather wisdom in crop disease management. The book brings together the latest research and knowledge on the impact of weather patterns on crop diseases, as well as practical strategies for leveraging weather wisdom to manage crop diseases. The book is designed to serve as a resource for farmers, extension agents, researchers, and policymakers who are interested in promoting climate-resilient crop disease management practices.
1.1 Role of Weather in Disease Managemènt
Weather plays a crucial role in the occurrence and spread of crop diseases. The development and dissemination of plant pathogens are significantly influenced by weather conditions such as temperature, humidity, wind, and precipitation (Fig 1.1). A climate change may alter the life cycle, survival, virulence and even genetics of a plant pathogen. Favorable environmental conditions are always a prerequisite for a pathogen to establish pathogenicity. Temperature is a critical factor in the development of crop diseases. Optimal temperatures vary among different pathogens, and temperatures that are either

Entomopathogenic nematode (EPN) viz., Heterorhabditis, Neosteinernema and Steinernema have been recovered from many regions of the world. They selectively infect many insects and a few other arthropods but do not adversely affect mammals or plants. They are actually vectors of pathogenic bacteria, cause relatively rapid death of the host (24 – 48 h) and show considerable potential in biological control of insect pests in the integrated pest management systems.

EPNs are similar to insect parasitoids in that the immature form develops at the expense of one host individual; they are ecologically similar to both parasitoids and arthropod predators because the host individually killed. However, these nematodes differ from predators and parasitoids in two ways: (1) the nematode is mutualistically associated with a bacterial pathogen which actually kills the host, and (2) the pathogenicity of the bacterium has a great influence on the efficacy of the system (Ehler, 1990). The purpose of this chapter is to introduce EPN as biocontrol agents in this refresher course and to provide an overview of some current issues in biological control of insects with particular emphasis on their relevance to the use of EPNs.

Biological control is defined as the action of natural enemies which maintains a host population at levels lower than would occur in the absence of the enemies. Natural enemies will include parasitoids, predators, nematodes, microbial pathogens and their gene products. Entomologists generally divide biological control into two categories: (1) natural biological control which is effected by native or coevolved natural enemies in the native home (origin) of a given insect and (2) applied biological control which due to human intervention. Applied biological control is further divided into classical biological control (introduction of exotic natural enemies) and augmentative biological control (enhancement of natural enemies already in place).

In insects nervous system is highly developed and serves to coordinate the activities of its various systems. Units of this system are known as neurons. Which carry information in the form of electrical impulses from external and internal sensilla (Sensory cells) to appropriate effectors e.g., glands, muscles and glail cells. Nervous system of insects may be divided into three parts.

1. Central nervous system
2. Sympathetic or visceral nervous system
3. Peripheral nervous system.

India’s agrarian culture and economy is undergoing drastic changes. In this progressive path of agricultural resurrection, a comprehensive multidimensional understanding of agricultural development is of great importance. In the present context of Kerala, where the local administrative bodies are vested with more powers to plan and execute need based agricultural development activities, a clear understanding of the concept of agricultural development among the major stakeholders shall serve as a firm base for development.

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems. Invasive species threaten and can alter our natural environment and habitats and disrupt essential ecosystem functions. Invasive plants specifically displace native vegetation through competition for water, nutrients, and space. Once established, invasive species can reduce soil productivity. The negative effects of invasive alien species on biodiversity can be intensified by climate change, habitat destruction and pollution. Isolated ecosystems such as islands are particularly affected. Loss of biodiversity will have major consequences on human well-being.

6.1. Speed Detection of Pests in China for Phytosanitary Programme

Phytosanitary procedures such as pest detection and identification rely on technology. With the rapid development of science, it is necessary for national plant protection organizations to keep informed and to make diagnoses more sensitive and accurate. Previous general pest detection methods frequently have limitations for the diagnosis of quarantine pests. In the past ten years, China has conducted considerable research into how to improve its diagnostic measures and methods.

6.1.1. General Pest Detection Measures and Methods

Traditional determination of morphology by microscope is used mostly to detect fungi and adult insects. The morphological method may be used, for example, in the separate identification of wheat dwarf bunt (Tilletia controversa), wheat karnal bunt (T. indica) and wheat common bunt (T. tritici). On the other hand, it is hard to detect seed-borne pests using the morphological method.

Isolation culture is also used to detect fungi and bacteria in China. It is an effective method for detecting seed-borne disease or systemic infection. However, it takes a long time (more than 1-2 weeks). Inoculating the indicated plant (a healthy plant that is a host for the suspected pest organism) is used mainly to identify viruses. This was the principal and time-consuming detection method used before immunological and molecular biological methods were developed. Because viruses are very important kinds of quarantine pests of young plants, effective and rapid methods for detection were urgently needed.

Concept of Inventory

‘Inventory’ may be defined as ‘usable but idle resource’. If resource is some physical and tangible object such as materials, then it is generally termed as stock. Thus stock or inventory are synonymous terms though inventory has wider implications. Broadly speaking, the problem of inventory management is one of maintaining, for a given financial investment, an adequate supply of something to meet an expected demand pattern. This could be raw materials work in progress finished products or the spares and other indirect materials. Inventory can be one of the indicators of the management effectiveness on the materials management front. Inventory turnover ratio (annual demand/average inventory) is an index of business performance. A soundly managed organization will have higher inventory turnover ratio and vice-versa. Inventory management deals with the determination of optimal policies and procedures for procurement of commodities. Since it is quite difficult to imagine a real work situation in which the required material will be made available at the point of use instantaneously, hence maintaining, inventories becomes almost necessary. Thus inventories could be visualized as ‘necessary evil’.

5.1 Introduction

Considering the richness of floristic diversity of India represented by 47,513 plant species, of which around are 9,500 reported to be of ethnobotanical botanical significance and around 7,500 - 8900 of ethnomedicinal importance (Anonymous, 1994; Pareek et al., 2005). It has been estimated that of these, around 5,000 plant species have been investigated in some detail in search for potential sources of wellness or health or medicinal drugs to cure various human ailments and diseases. As discussed in the previous sections, the Indian literature on medicinal aromatic plants formally documents information on about 2,500 medicinal and aromatic plants under various traditional systems with sufficient details. In addition, indigenous traditional knowledge exists for another 4,000-4,500 medicinal plant species based on long time experience/observations and their use by various tribes and communities and the individual clan or families in cure of specific ailments. However, this knowledge predominantly exists in oral traditions, which are under danger because of the threat to these traditional orthodox societies and loss of the dialect or languages in which they exist.

2.1 Introduction

India is known for its richness in bio-resources including floristic diversity and the associated cultural diversity that evolved over time and holds a vast amount of indigenous traditional knowledge (ITK) assembled over millenniums. The ability to convert this knowledge into wealth of products for social good through the process of innovation based on validation of available information holds great promise. In-depth studies using the modern technologies and further examination of potential sources will determine the future of India in the 21st century, commonly referred to as the century of scientific knowledge and technological expertise/advancements that belongs to Asia/India. In this regard, five technologies namely, biochemistry, biotechnology, herbal technology, information technology, and nanotechnology are going to be the most powerful elements that are crucial for ensuring prosperity, security, and welfare of the people of the nations and the globe at large. Production of an inventory of the medicinal aromatic plants with the associated knowledge evolved and documented over millenniums under different Indian traditional medicinal systems shall be the key in promoting and strengthening their exploitation and use under various herbal medicinal systems and/or under an integrated innovative combination of these with modern medicinal systems.

7.1 Introduction

The occurrence of different medicinal and aromatic plant species is often associated with a specific ecology and thereby, to a biogeographical or phytogeographical region of the Indian Subcontinent. The Indian Subcontinent is a confluence of at least two biogeographical realms, i.e., Palearctic or Palaearctic (Himalayas) and Oriental (Sino Indian- mainland India to much of insular the Southeast Asia). The most acknowledged classification of biogeographical zones was proposed by Udvardy (1975), which recognized 12 biogeographical provinces in India falling in these two realms. Based on varied climate, terrain, and faunistic information, Roger and Panwar (1988) tried to distinguish India into 10 distinct bio-geographical regions. Their classification did account for distribution of the plant-communities because they provided information about key components to identify the probable habitat for the presence of animals. An attempt for phytogeographical zonation, based on type of vegetation by Gadgil and Meher Homji (1990), distinguished 16 phytogeographical zones. Rodgers et al. (2002) further revised their biogeographical maps using geographical information system (GIS) techniques. They distinguished 10 biogeographical zones and 26 biotic provinces.

4.1 Introduction

The adverse effect of non-vegetarian diet, particularly red meat, on human health and on environment due to destruction/clearing of forest for raising more pasture and to increase the industrial production of grains for animal feed have led to greater greenhouse gas emissions, and environmental pollution due to extensive use of inorganic fertilizers, fungicides, pesticides. Clearing of forest has also caused extinction of plant species. For these reasons, greater interest has been generated in vegetarian diet based on the direct consumption of whole grains, legumes, nuts, fruits, and vegetables that are easily assimilated by the human body, nutritionally more efficient, and have least impact on the environment. In fact, the healthfulness of vegetarian diets has been found to be strongly correlated with sustainability of agriculture because of easy affordability of plant-based foods. Vegetarian people have been often referred to as vegan and pescatarian (including fish and other seafood). Most pescatarians include dairy and eggs as well. Similarly, allopathic medicines, which are synthetic inorganic concentrated drugs, have adverse effect on non-targeted organs, besides being expensive.

6.1 Introduction

The World Health Organization (WHO) compiled a list of 20,000 medicinal plants used in different parts of the world. An estimated 15,000 medicinal plant species, forming about 21% of the total plant species used for medicinal purposes in the world, fall in the endangered category (Schippmann et al., 2006). In India, medicinal plant species used under different traditional systems to a large extent are still gathered and collected from the wild in from of roots, bark, wood, stem and even the whole plant causing severe destruction of their habitat, resulting in loss of species/populations and erosion of genetic diversity. The remaining few are cultivated as crop plants, but marginally because of lack of assured market and can be safely termed as commercially under utilized and are also under threat. Therefore, despite India being rich in plants species with medicinal properties, genetic diversity within the species and the associated traditional knowledge regarding their use, the lack of awareness regarding the loss of species and genetic diversity due to destructive harvesting from the wild and many other factors, such as infrastructure development, iintroduction of exotic species is causing depletion of genetic diversity or loss of indigenous MAPs.

3.1 Introduction

India is rich in biological diversity as revealed by its floristic diversity comprising 17,926 species of angiosperm, based on which it has been considered one among the 17 mega-biodiverse countries of the world. Also, it is the centre of some of the oldest civilizations of world, starting with Vedic civilization. Using modern day scientific tools and technology backed up with shashtra pramaana, Vedic civilization has been calculated to be as old as 25000 years (Oak, 2018). Because of its rich ecological and biological diversity, Indian Subcontinent has inhabited a large amount of ethnic diversity, consisting of both the indigenous races and those moved from other parts of the world as settlers looking for greener pastures for better living. The major ethnic races are Caucasoid (Aryan), Dravidians, Mongoloid, Negroid, and Australoid. Anthropological Survey of India has identified 461 tribal communities (Xaxa, 1999), belonging to 227 ethnic groups (Pushpangadan et al., 2018) spread over 5000 forest villages. According to the 2001 census of India, the country has 122 major languages and 1599 other languages. Figures from different sources vary, primarily due to differences in definition of the term’s “language” and “dialect”. The largest of the language families represented, in terms of speakers, is the Indo-Aryan language family followed by the Dravidian language family.

ABSTRACT

Due to complex hydrogeological conditions it becomes very difficult to prospect the ground water resources especially in drought prone areas where the water table is very deep. The interpretation of geoelectrical sounding curves also becomes ambiguous. A semi empirical method namely theinverse slope method [Shankar Narayan and Ramanujachari, NGRI] is widely used since it is simple to operate without standard curves etc and it gives fairly good results. In some Government organizations like PWD [Ground Water Department] and TWAD Board of Tamilnadu, this inverse slope method is widely used for ground water exploration. Based on this methodology, ample of bore well points have been recommended in complicated hard rock terrains and the success rate is found to be encouraging. The study area, Kavalpatti, of Palani taluk in Dindigul district is a crystalline rock terrain, where geological, hydrogeological and geoelectrical investigations have been carried out to explore the ground water potential zone for agricultural purpose. The bore well drilled to a depth of 32 m has yielded 370 lpm. The interpreted geoelectrical section has been correlated with the litholog of bore well. Some bore well statistics [bore well points recommended based on this method] has been furnished, which reveals that this methodology is encouraging.

Nereistoxin (NTX) was originated from a marine annelid worm Lumbriconereis heteropoda and its analogue pesticides (table 51) including cartap, bensultap, thiocyclam and thiobensultap have been commonly used in agriculture, because of their low toxicity and high insecticidal activity.

ABSTRACT

Arunachal Pradesh in Northeastern India covers a major portion of the Eastern Himalayas and is well-known for its rich biological and cultural diversity. The indigenous communities of the state living in close vicinity of forests depend upon wild plant-resources for meeting their various needs like medicine, food, fodder, fuel, etc. The present paper deals with documentation of plant species used by Monpa and Adi community residing in vast ecological range starting from subtropical to alpine ecosystems. A total of 346 species belonging to 215 genera and 102 families used by the two communities as wild vegetables (97 species), wild fruits (39), dye and color (13), spices and condiments (51), hunting and piscicide (40), paper pulp and fiber yielding plants (5) and medicinal use were reported (165). This study highlights the rich diversity of indigenous knowledge among the local communities in utilizing the diverse plant resources around them for their sustenance. Documentation of this knowledge is of utmost importance for identification of useful plant species for value addition, promotion as well as to formulate strategies for their sustainable utilization and conservation. This would also enhance the livelihood of the indigenous communities contribute to biodiversity conservation in these fragile mountain ecosystems.

Abstract

Traditional knowledge on plants and their uses by tribal indigenous culture is helpful in the conservation of biodiversity. During 2017-2018, ethnobotanical investigations of the plants growing in Neelum Valley in District Bandipora (a part of Kashmir Himalaya) were carried out to collect information regarding different usages of the plants species growing in the region through questionnaire and interviews. Floristically, a total of 57 species belonging to 54 genera and 38 families were investigated to be used as medicine, food, fodder, timber, fuel wood, vegetable/edible fruit, resin yield and herbal tea purposes. On the basis of the floristic analysis of the study area, the leading family recorded was Asteraceae with (11%) species co-dominated by Rosaceae (9%). In terms of habit forms, herbaceous (70%) growth form is the most dominant. The most frequently used plant parts are leaves (26%) followed by whole plant (23%) and roots (19%). The plant documented cured different categories of diseases, the most common diseases such as diarrhea, fever, digestive problems, urinary troubles, rheumatism, eye diseases, skin diseases and wounds. Based on investigated knowledge, the data are discussed under sub-head as single, double and multi-diseases curing plants. The present study can provide a baseline data for future researchers, policy makers, common public, land managers, and the other stakeholders to develop scientifically-informed strategies for conservation of natural resources and sustainable use of plant resources in hotspot regions like Himalayas and other similar biodiversity rich sites.

Introduction

The smooth functioning of an organisation depends on its financial resources. For a newly established venture, it is important to accurately predict its financial requirements for the purpose of raising funds and assessing the profitability of the proposal. While the major investment in an organisation could be for short term and long-term purposes, there are multiple sources from which these funds could be raised. The conventional sources mainly include commercial banks and other financial institutions; non-conventional sources include lease financing, angel investors, venture capitalist firms, factoring, and bill discounting.

Finance is the basic requirement for the smooth functioning of any organisation. Finance is required to meet the short-term and long-term requirements of a f irm. While the short-term fund is required to meet day-to-day expenses, long term funds are required for the acquisition of long-term or fixed assets that would yield benefits in the future, financing the permanent part of working capital, and for the growth and expansion of a business.

The quantum of both finances depends upon the nature and size of the business’s organisation, and the sources from which one acquires these funds also have a multi-dimensional range.

In today’s innovation driven economies, turning a great idea or new technology into something investors want to fund takes careful planning. This process is called investor readiness. which means making sure the idea works, has a market, and is presented in a way that makes investors feel confident. Therefore, Investor readiness means the preparedness of an innovation to attract and secure investment from potential investors. It has all the essential parameters in place that an investor would evaluate before deciding to invest. For inventors, this means showcasing innovation’s business potential, potential for growth, and the capability to provide a return on investment. Understanding investor readiness is important because it directly influences scalability and growth of invention. Even the most innovative ideas can struggle to find the financial benefits without showcasing business potential.
Why it is important to discuss investor readiness
Investor readiness is the state in which a technology, its value proposition, and its founding team are significantly prepared to engage with securing funding from potential investors. Without investor readiness, even high-potential innovations may fail to reach the market due to gaps in business clarity, legal assurance, or team maturity. TTOs play an important role in this process by acting as intermediaries between inventor and investors. Modern day TTOs are more inclined to prepare technologies and associated teams to attract investment. This expanded mandate of TTOs and brought in investor readiness. It requires a wellstructured approach focused on aligning academic innovations with investor expectations. TTOs help in creating this readiness by guiding researchers through commercial pathways, derisking technologies, and translating technical advancements into investment suitable.

ABSTRACT

Agriculture can act as a catalyst in accelerating growth and reducing poverty. Agriculture can be an important engine of growth and poverty reduction. But in spite of its futuristic capabilities, the sector is underperforming because the productivity is reduced because of the constraints faced by the women in agriculture and allied sector. The women are the backbone of agricultural workforce but worldwide their hard works have mostly been unpaid. They have to perform most tedious and back breaking part of work in agriculture, animal husbandry and at homes. The tribal women play a significant and crucial role in agricultural development and allied fields including in the main crop production, livestock production, horticulture, post harvest operations, agro / social forestry, fisheries, etc. Tribal women have to manage, often, complex and multiple livelihood strategies. Their activities typically include producing agricultural crops, tending animals, processing and preparing food, working for wages in agricultural or other rural enterprises, collecting fuel and water, engaging in trade and marketing, caring for family members and maintaining their homes. Women’s participation in rural labour markets varies considerably across regions, but invariably women are over represented in unpaid, seasonal and part-time work, and the available evidence suggests that women are often paid less than men, for the same work.

ABSTRACT

Rural youths represent both a challenge to and an opportunity for reducing rural poverty. To overcome this challenge and seize the opportunity concerted efforts are needed to generate decent employment opportunities. A complementary set of awareness generation, entrepreneurship development, enabling policy, capacity building and technical support activities need to be designed for creating an enabling environment that meets the multi-dimensional needs of rural youths. Sustainable poverty reduction and rural economic development can only be achieved when national enabling environments facilitates and empower young people to achieve their full potential. Agriculture being the core of rural activity, potentiality of farming sector to create employment opportunity both in primary as well as in secondary agriculture needs to be highlighted with proven success before the rural youths. Enabling environment in all aspect needs to be created to motivate the educated youths to live in villages and launch a new agricultural movement based on integrated application of science and social wisdom. The untapped demographic dividend will become our greatest strength when the aspiration turns into reality.

20.1 Exchange Capacity

Soil colloidal particles carry both negative and positive charges on their surface which attract and hold equivalent amount of oppositely charged ions to their surface. The total number of negative charges present on a given mass of soil or capacity of a given mass of soil to exchange cations or total number of cation held by a given mass of soil is termed as cation exchange capacity (CEC). Similarly, the capacity of a soil to retain anions is known as anion exchange capacity (AEC). The ion exchange capacity of a soil depends upon the type and amount of colloidal particle (clay and organic matter) present in the soil. Ion exchange capacity (CEC/AEC) is expressed as milliequivalent ion (cation/ anion, respectively) per 100 g of soil (meq/100g). It is also expressed as centimoles of charge (positive/negative) per kg of soil [cmol (±) / kg]. Meq/ 100g = cmol (±) / kg of soil.

20.1.1 Determination of Cation Exchange Capacity of Soil Principle

Soil is first saturated with normal ammonium acetate (pH 7.0). Excess ammonium (NH₄⁺) ions and displaced cations are then removed by washing with alcohol. The amount of NH₄⁺ ions retained by the soil is measured by steam distillation of NH₄-saturated soil with MgO. During distillation evolved ammonia is absorbed in a boric acid solution as ammonium borate and the amount ammonium borate formed is determined by titration with standard sulphuric acid in presence of mixed indicator.

13.1 Exchange Capacity

Soil colloidal particles carry both negative and positive charges on their surface which attract and hold equivalent amount of oppositely charged ions to their surface. The total number of negative charges present on a given mass of soil or capacity of a given mass of soil to exchange cations or total number of cation held by a given mass of soil is termed as cation exchange capacity (CEC). Similarly, the capacity of a soil to retain anions is known as anion exchange capacity (AEC). The ion exchange capacity of a soil depends upon the type and amount of colloidal particle (clay and organic matter) present in the soil. Ion exchange capacity (CEC / AEC) is expressed as milliequivalent ion (cation / anion, respectively) per 100 g of soil (meq / 100g). It is also expressed as centimoles of charge (positive / negative) per kg of soil [cmol (±) / kg]. Meq / 100g = cmol (±) / kg of soil.

This technique is used in the separation of ionised and ionisable compounds.It consists of an insoluble matrix to which charged groups are covalently bound. The charged groups are associated with mobile counter ions. These counter ions can be reversibly exchanged with other ions of the same charge without altering the structure of the matrix.

The ion exchanger is complex and polymeric. The polymer carries an electric charge that is exactly neutralized by the charges on the counter ions. These active ions are cations in a cation exchanger and anions in an anion exchanger. A cation exchanger consists of polymeric anions and active cations whereas anion exchanger consists of polymeric cations and active anions. Amberlite IR 120 and Dowex 50 WX are cation exchangers while Amberlite IRA 400 and Dowex 1X are anion exchangers. Ion exchangers should be insoluble in water and hydrophilic to allow the ions to pass through. It should be chemically stable and should be denser than water when swollen.

Cation Exchange of Clay Minerals in Soil

The term “clay mineral” refers to phyllosilicate minerals and to minerals which impart plasticity to clay and which harden upon drying or firing. Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth’s surface. Clay minerals in soil play a significant role in exchanging cations, which are positively charged ions, and in regulating soil fertility and nutrient availability. Cation exchange capacity (CEC) is a measure of a soil’s ability to exchange cations and is influenced by the type, abundance, and charge properties of clay minerals in the soil. Clay minerals have a high CEC due to the presence of charged surfaces (silanol and alumoxane groups) that can exchange cations with the soil solution. The most common cations exchanged by clay minerals are hydrogen (H+), calcium (Ca2+), magnesium (Mg2+), potassium (K+), and sodium (Na+). When a soil solution comes into contact with clay minerals, cations in the soil solution are adsorbed or attracted to the charged surfaces of the clay particles.

The exchange of ions (cations or anions) are important phenomena in soil for the growth and nutrition of the crops. The oppositely charged ions are being adsorbed by the clay colloids which are subjected to be released or exchanged reversibly from the soil solution. The participating ions in the exchange process are called exchangeable or counter ions. The activity of ions depends on the pH of the soil. Hence, factors like, soil texture, organic matter, concentration of ions could govern the ion exchange phenomena in soil.

6.0 Ion Exchange

Ion exchange is a reversible process where exchange of ions are possible between the two electrolytes or between an electrolyte solution and a complex. The ion exchange processes help in purification, separation, and decontamination of aqueous and other ion-containing solutions. The ion-exchange resins (functionalized porous or gel polymer), zeolites, montmorillonite, clay and soil humus are considered as typical ion exchangers which are either cation exchangers [exchanging positively charged ions (cations)], or anion exchangers [which can exchange negatively charged ions (anions)].

8.1. What is an ion exchange reaction and its application in soil system

Ion exchange is a reversible chemical reaction between two substances, either between two electrolytes or between an electrolyte solution and a solid complex as well as between two solid phases (if in close contact with each other), where ions of equal charge may be interchanged in equivalent proportion.

Organic colloids and inorganic micelles (clays) are sites of ion exchange. Soil contains silicate clay minerals which exhibit charges due to isomorphous substitution as well as due to the pH dependant charges for ionisation of hydrogen and hydroxide functional groups. Organic matter present in soil also contributes to the pH dependent charges due to the presence of various active functional groups. Thus, the organic and inorganic colloids present in soil bear positive or negative charges. Electric charge on soil particles is neutralized by equivalent amount of oppositely charged exchangeable counter ions, held by coulomb forces and van der Waals forces. Ca⁺², Mg⁺², H⁺, K⁺, Na⁺, NH₄ ⁺, Al⁺³, Fe⁺³, Fe⁺², Mn⁺², etc. are the common cations present in soil where Ca⁺² serves as the dominant ion. However, Na⁺ and Al(OH)₂ ⁺ are the dominant cations found in the exchangeable phase in strong alkali and strong acid soils, respectively. SO₄ ^- 2, Cl^-, HCO₃ ^-1, NO₃ ^- etc. are the most common anions found in soil to neutralize positively charged soil colloids.

Ion Exchange Defined

By ion exchange is meant “the reversible process by which cations and anions are exchanged between solid and liquid phases, and between solid phases, if in close contact with each other”. For exchange of cations the term “base exchange” is exclusively used.

Agriculture has long served as the backbone of human civilization, enabling societies to grow and prosper. For generations, farmers have relied on experience, traditional practices, and historical weather data to inform decisions about crop cultivation and livestock management. Yet these conventional methods often left operations vulnerable to unpredictable environmental conditions. Today, the integration of the Internet of Things (IoT) is transforming agriculture by shifting the approach from reactive management to proactive, data-driven decision making. Modern IoT systems deploy a network of interconnected sensors that continuously capture critical environmental parameters such as soil moisture, temperature, humidity, light intensity, and nutrient levels. These sensors provide granular, real-time data that is transmitted to centralized analytics platforms where it can be processed and visualized. The resulting insights empower farmers, aquaculturists, and animal husbandry professionals to optimize every aspect of their operations — enhancing yields, reducing waste, and increasing sustainability. This chapter explores the deployment and impact of IoT in agricultural and allied systems. It provides detailed technical discussions on sensor networks, communication protocols, and power management; illustrates how real-time data integration with advanced analytics transforms decision making; and presents in-depth case studies from initiatives such as John Deere’s precision agriculture systems, Microsoft FarmBeats, and regional projects like SmartAgriHubs. Moreover, the chapter delves into the formidable challenges of IoT deployment, including those faced by underdeveloped regions—and concludes with a look at emerging trends and a synthesis of the future vision for agriculture.
6.1 The Role of IoT in Modern Agriculture
6.1.1 Revolutionizing Data Collection
The most significant impact of IoT in agriculture is its transformation of data collection. Traditional methods relied on periodic field observations, manual sampling, and regional weather reports that provided only a snapshot of environmental conditions. In contrast, IoT devices continuously monitor the microclimate across a farm. With sensors distributed throughout fields, livestock facilities, and aquaculture systems, farmers can now capture real-time data on temperature, humidity, soil moisture, light intensity, and more (Fig.6.1).

Introduction

Modern-day agriculture and civilization together demand increased production of food to feed the global population. New technologies and solutions are being applied in the agricultural domain to provide an optimal alternative to gathering and processing information while enhancing net productivity. At the same time, the alarming climate change and increasing water crisis demand new and improved methodologies for modern-age agricultural and farming f ields. Automation and intelligent decision-making are also becoming more important to accomplish this mission in flower production. In this regard, the Internet of Things (IoT) ubiquitous computing, wireless ad-hoc and sensor networks, radio frequency identifier, cloud computing, remote sensing, etc. technologies are becoming increasingly popular.

Most of the IoT-based applications are targeted for various applications. For example, IoT for environmental condition monitoring with information on soil nutrients are applied to predict crop health and production quality over time. Irrigation scheduling is predicted with IoTs by monitoring the soil moisture and weather conditions. The world’s first IoT device was invented in the early 1980s at Carnegie Melon University.

Artificial brainpower (Artificial Intelligence) is quite possibly of the quickest developing innovation in this cutting edge world. Artificial intelligence is presently broadly utilized in different enterprises going from the improvement of mechanical technology to the observing of natural issues. Computer based intelligence innovation has evident extensions in medical services gadgets, self driving vehicles, satellite imaging, scene planning, Climate change checking, also medical services frameworks. Artificial intelligence has heightened the improvement of mechanical technology across the globe that has made the life very simpler and added to a greatly improved existence of prosperity. Artificial intelligence interceded robot of a few areas including farming will create great quality items with more positive effects on Climate. Artificial intelligence utilizes various Smart sensors that cycle information progressively with higher precision. Consequently, Artificial intelligence has upgraded the presentation of any gadget to a few folds with more prominent reasonableness and Precision in their results. Computer based intelligence with Smart sensors has lead to the improvement of a cutting edge innovation called as Internet of Things (IoT). IoT is center of remote frameworks and Artificial intelligence manages information progressively and creates suitable results. This innovation has been taken on in pretty much every area of science and examination. IoT based advanced advancements can possibly create inventive models for improved creation of buyer items including agro-items.
Agriculture is fundamental piece of people local area. It is overhauled with time to increment rural production. Present day advancements has additionally been utilized in farming, agriculture, also ranger service for better observing of plant development, sicknesses, and bug populace. Artificial intelligence and IoT have various expanding extensions in farming to settle different issues such as soil conditions, Climate status, bother discovery, assurance of collecting time, etc. Likewise computer based intelligence and IoT offers fantastic extensions for continuous observation of temperature, dampness, contamination, soil quality, water content, radiation, and others.

The name Ipecacuanha is from the Portuguese meaning, 'Road-side-sick-making plant⁷, and mention of it as a remedy for the bloody flux or dysentery goes back as far as the late sixteenth century.

The principle feature of Ipecacuahna is its persistent nausea and vomiting, which form the chief guiding symptom. Indicated after indigestible food, raisins, cakes, etc. especially indicated in fat children and adults, who are feeble and catch cold in relaxing atmosphere, warm moist weather.

One cannot think of treating persistent nausea without Ipecac. This is a nausea in which there is no relief by vomiting. The patient is as sick after as before. The second major problem for which Ipecac is a great cure is a chest complaint, bronchitis in infants, bronchitis with coarse rattling. Ipecac is also a remedy for infections of the upper respiratory tract wherein a peculiar wheezing sound is produced on breathing out. Old incurable cases of asthma are relieved by Ipecac. Ipecac is useful in uterine haemorrhages.

H orticultural crops are most important ones incurring huge amount of pesticides in our country. The intensity of esticides on them is highest per unit area. However research on integrated pest management has not matched the progress and problems of plant protection at large and protected cultivation in particular. The USA, UK, Israel and Russia, pioneers in protected cultivation, are able to harvest productivity of up to 500 tonnes/ha of tomato and 200 tonnes/ha each of cucumber and capsicum, while in India up to 300 tonnes/ha of tomato and 100 tonnes/ha each of cucumber and capsicum are obtained, has compared to normal open field where their yield ranges from 40 to 60 and 10 to 20 tonnes/ha in India, respectively.

The sustainability of an agro-ecosystem is represented by its ability to maintain a given level of productivity over time and a given quantitative-qualitative level of environmental resources (Loucks, 1977). The greenhouse is also a form of agro-ecosystem, where unlike other agro-ecosystems, environment has been adapted to crop in order to maximize its productivity. The greenhouse system has to take maximum advantage of natural benefits offered by location in certain latitudes while minimizing the disadvantages (Castilla, 2002). Higher productivity under such protected cultivation is attainable mainly on account of reduced competition, healthy environment, better nutrient management, increased surface area and longer crop duration. However, ideal and stable environment with warm, humid and abundant food under protected conditions provides an excellent platform for pest development often more than open field crops, leading to severe pest situations in greenhouses, as revealed by extensive surveys.

Reducing insecticide application to the lowest level is the motto of IPM in vegetables. Monitoring for the initial build up and timely mechanical removal of the first population is a must in vegetables. Always remove the first affected plants, by diseases like mosaic, and destroy them by burying or burning. Remove insect eggs, insect affected plant parts and adults and immature stages of insects, and destroy them every day. Do not throw them in the field. They will either come back, or pupate and attack later. During nursery stage, use wood ash, cow dung solution, and plant extracts to deter all pests. Use only low residual insecticides like Dichlorvos 1ml/l, Malathion 2ml/l, Endosulfan 2ml/l or Quinalphos 2ml/l, in spots, at the beginning of attack itself.

Introduction

Insect pests cause enormous loss to horticultural crops through direct and indirect invasion on various plant parts. It is estimated from the available information in the literature that there are about 1000 insect pests species on about 100 major and minor horticultural crops in India (Sharma et al., 2011).  The yield and quality of produce are central system point to the sustainable horticultural production. If not properly managed, pests can dramatically reduce crop yield, quality and subsequent returns. We invest a lot of time, money and natural resources into growing horticultural crops. Good pest management could protect this investment from avoidable losses.

Introduction

It is a well known fact that agricultural pests cause substantial crop losses throughout the world. In the past farmers had to manage this problem to secure their basic subsistence needs, and as a response, the farmers practiced and developed cultural and mechanical pest control based on trial and error. Over a period of time, these practices have become a part of their production management system. The first known chemical control dates back to 2,500 years. From the late 1800s to 1940s, the main insecticidal compounds used were oils, soaps and resins, plant-derived poisons and inorganic compounds. The chemical age began in the 1940s with the discovery of dichloro diphenyl trichloroethane (insecticide), ferbam (fungicide), and 2, 4-D (herbicide) (Arneson and Losey, 1997). In 1940s and 1950s, pesticides were thought to be the final word in pest control and their introduction contributed substantially to raising agricultural productivity in many regions of the world. Since then, pesticides have become an integral component of many intensive agricultural systems. Repeated applications of pesticides lead to resistance in the pest (Beaument, 1993). This resistance results in the increased application of pesticides and to the collapse of the agricultural systems characterized by highly resistant pests, with no natural enemies left to control them. Pesticides have been found to causeacute and chronic human health problems, contamination of groundwater, surface water, atmospheric contamination, and negative effects on non-target organisms (Mullen, 1995). Concerns about the negative effects of pesticides led to research and promotion of alternative pest control practices – Integrated Pest Control or simply IPC. This new concept called Integrated Pest Control (IPC) and later Integrated Pest Management (IPM) was stimulated by symposia organized by the Food and Agriculture Organization (FAO) of the United Nations in 1966. IPM made a paradigm shift in the philosophy of pest control, from pest eradication to pest management. Instead of single tactic control, emphasis was placed on the use of a combination of available tactics in a compatible manner aimed at providing cheap, long term sustainability with minimum of harmful side effect and controls the pest at ETL level.

Introduction

Chemical pesticides play an important role in plant protection in India and most of the developing countries of the world. These synthetic organic insecticides provide spectacular control of insects. Chemical control is one of the effective and quicker methods in reducing pest population. However, over reliance and injudicious use of pesticides resulted in a series of problems in the agricultural ecosystem mainly, the development of resistance in insects to insecticides, pest resurgence, outbreak of secondary pests into primary nature, environmental contamination and residue hazards, destruction of natural enemies of insect pests etc. All these problems aggravate the pest problem in agricultural crops. Thus, the importance of eco-friendly pest management techniques is being realized more and more in the recent past. The modern concept of pest management is based on ecological principles and involves the integration of different control tactics into a pest management system. This is not altogether a new concept. It was practiced before the advent of modern chemicals. Integrated Pest Management is an ecological approach in which utilization of all available techniques of pest control to reduce and maintain the pest population at levels below economic injury level. The UN’s Food and Agriculture Organisation defines IPM as the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment. IPM emphasizes the growth of a healthy crop with the least possible disruption to agro-ecosystems and encourages natural pest control mechanisms. A well-defined Integrated Pest Management (IPM) is a program that should be based on prevention, monitoring, and control which offers the opportunity to eliminate or drastically reduce the use of pesticides, and to minimize the toxicity of and exposure to any products which are used. So, IPM is an eco-friendly approach which encompasses cultural, mechanical, biological and need based chemical control measures.

Introduction

‘IP’ refers to unique, value-adding creations of the human intellect that results from human ingenuity, creativity and inventiveness. An IP right is thus a legal right, which is based on the relevant national law encompassing that particular type of intellectual property right. Such a legal right comes into existence only when the requirements of the relevant IP law are met and, if required; it is granted or registered after following the prescribed procedure under that law. All countries around the world have a national legal system of intellectual property rights which has developed over varying periods of time during the last 150 years or so. It has enabled the grant of property-like rights over such new knowledge and creative expression of mankind, which has made it possible to harness the commercial value of the outputs of human inventiveness and creativity. This is usually done by its orderly use, exchange or sharing it amongst various types of business partners in a complex network of strategic relationships that generally work harmoniously during the new product development process for creating and marketing new and improved goods and services in domestic and export markets.

IPR is a tool for Innovation and reward for it. Innovations are concerned with the commercialization of new ideas; in contrast, an ‘invention’ may not be directly associated with commercialization. As such, innovation may be seen as a process of interaction and feedback during the various stages of the new product development process. An invention is considered as the generation of a new idea or knowledge, which aims to solve a specific technical problem. Inventions could relate to products or processes and are characteristically protected by trade secrets, utility models/petty patents or patents. Utility models/petty patents or patents are granted/registered under the relevant national/regional law by the relevant national or regional patent office. As not all inventions are commercialized, so it is clear that not all inventions result in innovations.

Keeping in view the importance of intellectual property rights and their protection, Journal of Intellectual Property Rights (JIPR) was started in 1996. The objective of the journal is enhancing communication between policy makers, organizational agents, academics, and managers on the critical understanding and research on intellectual property; and to promote the development of the newly cultivated research field. The journal publishes contributed/invited articles, case studies and patent reviews; technical notes on current IPR issues; literature review; world literature on IPR; national and international IPR news, book reviews, and conference reports.

JIPR is covered in the abstracting/ indexing services namely Scopus, EBSCO host Electronic Journals Service, Directory of Open Access Journal, Library & Information Science Abstracts database and Legal information Institute of India database.

ABSTRACT

This paper attempts to portray prevailing scenario of IPR in the light of globalization with special emphasis on harmonization of IPR systems and laws of different countries. 

INTRODUCTION

The globalization of information, facilitated by the Internet, has significant implications for intellectual property regimes of national and international levels. Assessment of these implications and their probable outcomes is unavoidably value-driven. Globalization represents ever-increasing influence of developed nations and transnational entities over developing and less developed nations. The process has also brought in significant changes in understandings of sovergenity. An analysis of the implications of globalization of information on international and domestic intellectual property rights and legal regimes is a complex endeavor.

Abstract

Majority of basic research in our country has foundations in Universities and various Institutions linked to them. This paves way for discovering wilder varieties of the present known cereals and other food crops. Such findings help in bioprospecting the required gene/genetic material for the improvement of the existing crops. As per the Biodiversity Act of 2002, it is the responsibility of these institutions to document the same. But, as research scientists are geared to meet the challenges? Being used to socialistic system from the days of Independence where knowledge generated was open to everyone or closed and kept under the mountains of files, the TRIPS agreement has come as a shock. But the true impact of it was realized in 1999-2000, when the patent amendments were taken up. The private institution/ companies went into the act immediately.  We in the University neither were slow to react nor were we prepared to take the shock.  In this paper some of the problems pertaining to IPR and scenario of Indian Universities and Institutions in this regard were highlighted.

Introduction

A little information when shared can go a long way. Information patented can elevate India to great heights. Property (tangible) is associated with physical objects: house, land, etc., while intellectual property (intangible) includes Patents, Trade secrets, Copyrights, and Trademarks. Intellectual property rights (IPR) are legal rights which result from intellectual activity in industrial, scientific, literary, and artistic fields. Intellectual property protection (IPP) is right to protect intellectual property. Various types of IPR are:

The World Trade Organization (WTO) is an international organization designed to supervise and liberalize international trade. It was established on 1^st January 2005 and is responsible for making and enforcing rules for trade between nations. WTO marks a major change in global trade rules. As an organization, it replaces the General Agreement on Tariffs and Trade (GATT), which had been in existence since 1947. The Eighth Round of Multilateral Trade Negotiations under GATT, which started in Uruguay in 1986, was concluded in 1994, leading to the creation of WTO as the new permanent international trade organization. The role of WTO is much more extensive than that of GATT, which dealt with trade in goods. Apart from goods, the two other broad areas that WTO covers are services and intellectual property, which previously belonged to the domestic domain. Accordingly, WTO administers not only the Multilateral Trade Agreements (MTAs) in goods but also the General Agreement on Trade in Services (GATS) and the Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPS), which came into existence with WTO. All the agreements annexed to the Agreement establishing the WTO were signed as part of a package deal. Member countries did not have the option of choosing some and rejecting others. Another important difference with the erstwhile GATT is that WTO has a stronger compliance mechanism than did GATT-a member’s failure to meet the obligations can invoke retaliation across agreements and sectors.

Intellectual Property Right, IPR is a general term covering patents, registered design, trademarks, copyrights, layout design of integrated circuits, trade secrets, geographical indicators and competitive practices in contractual license.

1. Introduction

Iran, with an area of 1648 thousand sq.kms.,  is situated in the eastern portion of the northern hemisphere, in the south west of Asia, and is considered as one of the Middle East countries. Iran is a mountainous country with a variety of climates. The average temperature and rainfall for the whole country are quoted as 18ºC and 240 mm respectively (CAPES, 1996). The country is also organized into 28 provinces. Over the past two decades, rapid rate of population growth has been a major source of concern in Islamic Republic of Iran. The population of the country passed the 60 million figures in 1993 and is projected to reach 86 million by the year 2010. In fact, the Iranian population has doubled in this period (CAPES, 1996). For example, according to the 1991 census, the female population of 15 years and above was 15 million (Anonymous, 1998). However, thanks to considerable investments and well-organized and directed national population planning program, population growth rate is now 1.5 percent in the urban and two percent in the rural areas. At the national level, the figure is 1.65 percent (CAPES, 1996).

1. INTRODUCTION

The agricultural paradigm in the developing world including Iran will have to be recast to take advantage of knowledge availability to achieve multiple goals of income, food, jobs, etc. Although, many farming communities in developing countries need timely expert advices to make them more productive and competitive, they are still facing a multitude of problems to maximize agricultural productivity. In spite of successful and promising researches conducted on new agricultural practices, majority of the farmers are not getting upper-bound yield due to several reasons. One of them is that scientific agricultural advice is not reaching the farming community in a timely manner. A wide information gap exists between research and practice.

To cope with this problem different countries have taken various measures. What is common in the extension systems of developing countries is that in a backdrop of rapid organizational and social changes in agriculture, new hardware and software devices have to be applied for better responsiveness to increasing farmers demand for timely and accurate information. At the pace of recent progress in ICT, within a decade it will be possible to provide instantaneous connectivity to millions of people, enabling mass customization and personalized services (Reddy and Ankaiah, 2005). Data mining technology can be used to extract useful knowledge from huge database and simulation technology can be used to predict in to the future (Wiederhold, 2002).
