ABSTRACT

Wavelet analysis is a technique possessing mathematical properties and it has been used by the scientific research community for its power to analyse rapidly changing transient signals used to represent data or functions - the wavelets used in the analysis are, however, functions that break the data down into different scales or resolutions. Wavelets possess the competence to handle spikes and discontinuities than traditional Fourier analysis and make the noisy data to de-noisy. Though traditional applications of wavelets have focused on image compression and analysis, wave propagation but they are also being used to analyse time series, biological processes, spectroscopic data of chemical compounds, seismic signals for earthquake prediction, atmospheric data for weather prediction, computer graphics, medical image technology, detection of aircraft and submarines, non-parametric regression, density estimation, and long memory wavelet models. Indeed, wavelets permit complex information such as music, speech, images and patterns to be decomposed into elementary forms at different positions and scales and subsequently being reconstructed with high precision. Signal transmission is based on the transmission of a series of numbers, indeed, the series representation of a function is important in all types of signal transmission.Wavelet transform of function is the improved version of Fourier transform. Fourier transform is a powerful tool for analysing the components of a stationary signal. But the Fourier transform fails to analyse the non-stationary signal where as a wavelet transform allows the components of a non-stationary signal to be analysed.

ABSTRACT

Rose (Rosa hybrida Linn.) is universally acclaimed as the ‘Queen of Flowers’. But this woody plant is considered less amenable to in vitro culture as compared to herbaceous plants. This is due to the fact that the establishment rose explants is difficult due to heavy phenolic exudation. In the present study, this problem was solved by a very simple and cost effective method. The cut ends of the explant were sealed with wax after thorough sterilization. Ten different explant collection periods with 20 different hormonal combinations in MS culture medium were taken for establishment. The winter dormancy period (Mid- December) was considered best for explant collection and showed 85% survival. Amongst the hormonal combinations 5mg/l BA coupled with 0.05mg/l NAA was considered the best. The average number of leaves (7.5) and average shoot length (7.3 cm) was also highest in this treatment, 15 days after culture establishment.

The adjustment and maintenance of soil pH at a value suitable for optimal crop production is the first step in soil management, because soil pH affects soil properties, nutrient availability and plant nutrition. In India, about 30M ha cultivated  land  suffer from high soil acidity (pH < 5.5). These soils are critically degraded and are of poor health producing crop yields, which are often less than 50% of that in normal soils. Due to this, farmers use much less fertilizers for crops (50 to 80 kg NPK ha^-1), since this is not profitable.

As we conclude this comprehensive review of the complex relationships between weather, crop diseases, and disease management, it is essential to reflect on the current state of knowledge and identify areas that require further research and attention. The preceding chapters have highlighted the significant impacts of weather factors on crop diseases, emphasizing the need for a deeper understanding of these relationships to develop effective disease management strategies. Significant work particularly on effects of different weather combinations on pathogen population and disease severity needs to be addressed well in time. Despite significant advances in our understanding of the weather-crop disease nexus, there remain substantial knowledge gaps that hinder our ability to predict and manage disease outbreaks effectively. For instance, the complex interactions between weather factors, crop physiology, and disease development are not yet fully understood, making it challenging to develop accurate predictive models. Furthermore, the impacts of climate change on weather patterns and crop diseases are still being researched, and more work is needed to understand these relationships fully. To address these knowledge gaps and improve our understanding of the weather-crop disease nexus, several action plans are required. Firstly, continued research is needed to elucidate the complex relationships between weather factors, crop physiology, and disease development. This research should focus on developing a deeper understanding of the underlying mechanisms driving these relationships, as well as identifying key weather thresholds that trigger disease outbreaks. Secondly, the development of accurate predictive models that can forecast disease outbreaks based on weather data is critical. These models should be able to account for the complex interactions between weather factors, crop physiology, and disease development, as well as incorporate data from multiple sources, including weather stations, satellite imagery, and field observations. Thirdly, there is a need for more effective communication and collaboration between researchers, policymakers, and farmers to ensure that research findings are translated into practical disease management strategies. This will require the development of user-friendly decision support tools that can provide farmers with timely and accurate advice on disease management, based on weather forecasts and other relevant data. Finally, addressing the impacts of climate change on weather patterns and crop diseases will require a coordinated effort from researchers, policymakers, and

Introduction

Bougainvillea is a popular ornamental plant in the tropics and sub-tropics of the world. The plant is mainly grown for its attractive bracts in wide array of colours which splash colour to the surrounding where it grows. Wide adaptability to different agro-climatic conditions and easy multiplication has made it a popular ornamental plant of the world. The mass effect of the colourful bracts of Bougainvillea can alter the face of any given place in a magnificent way which could not be achieved by punctuating any other plant. The flowering of Bougainvillea is compared with the Azalea of temperate countries and very truly called as Glory of the Tropics.’

The popularity of Bougainvillea has now crossed from tropical to temperate countries and successfully being grown as pot plants in green houses. Selection of cultivars of Bougainvillea spectabilis and B. peruviana for temperate region is recommended for better result. Availability of a large number of cultivars under horticulturally important species, provide a unique scope to the Bougainvillea lovers for wide choice according to their need. Single bracted cultivars with large bracts in different colours are obvious choice for every landscape designer while double bracted cultivars produce mass effect of colour as specimen plant. Considering its ornamental and commercial importance in nursery trade, R & D work were taken up by different national research institutes (IARI, IIHR, NBRI, BARC), agricultural universities, Agri-Horticultural Societies (Kolkata and Chennai) and even by progressive nursery men. As a result, a large number of new cultivars have been developed in India. Considering the contribution made by India, The international registration authority for new cultivars lies with The Indian Agricultural Research Institute (IARI), New Delhi which is an international recognition conferred upon by International Society for Horticultural Science.

Recently, lot of development taking place for further popularization and exploitation of Bougainvillea around the world by way of development of new cultivars, standardization agro-technology suited to different zones. Countries like Thailand, Singapore, Malaysia and India have been excelling in this area. Establishment of American Bougainvillea Society is another landmark in Bougainvillea cultivation.

The march of weather factors during crop period is never smooth and regular. Agriculture, because of its dependance on climate is inevitably subjected to unpredictable long and short term fluctuation characteristic of atmosphere conditions. Climate introduces an element of risk in farming which makes it particularly hazardous occupation.

A Weather hazard in this context can be defined as any type of extreme weather condition that can damage the crops and animals leading to abnormal decrease in production and income. The extent to which these hazards create risk depends on the time of occurrence, intensity and duration of the hazard besides the age, stage of development and inherent resistance of the crop or livestock involved. Major abnormalities affecting the crop production are:

Agriculture, the cultivation of life that sustains human civilization, is profoundly intertwined with the rhythms of the natural world. Of all the environmental factors that influence farming, weather reigns supreme, orchestrating a complex symphony of elements that dictate the success or failure of crops. This chapter delves into the intricate relationship between weather and agriculture, exploring how temperature, precipitation, sunlight, and other atmospheric conditions shape every facet of agricultural production.
Weather’s influence begins with the very first stage of a plant’s life. Temperature governs seed germination and seedling development, while sunlight provides the energy for photosynthesis, the process by which plants convert light energy into chemical energy. The availability of water, dictated by rainfall patterns, is crucial for plant growth and nutrient absorption. Wind patterns can aid in pollination but also cause damage to crops.
Throughout the growing season, weather continues to play a critical role. Optimal temperatures are essential for each stage of plant development, from flowering to fruit production. Adequate rainfall, or irrigation to supplement it, ensures healthy growth and abundant yields.
Extreme weather events, such as droughts, floods, heatwaves, and frosts, can have devastating consequences for agriculture. These events can destroy crops, reduce yields, and disrupt food production, leading to economic losses and food insecurity (Fig. 18.1).

Weather and climate have great influence on farm animal production. The environment in which an animal lives is referred to as its habitat. A habitat includes both biotic (living) and abiotic (nonliving) components of the animals’ environment. Abiotic components of an animal’s environment include temperature, humidity, oxygen, wind, soil composition, day length and elevation. Knowledge of how potential environmental stressors (ambient temperature, humidity, thermal radiation, air speed, etc.) can directly and adversely affect animal performance, health and wellbeing is also required for a successful animal farming. The indirect consequences of weather include their impact on feed quality and availability.

Birds and mammals are warmblooded (endotherms or homeotherms), possessing a thermoregulatory system that maintains a stable body temperature and uniform internal environment (homeostasis) by converting food energy into heat. All metabolic processes generate substantial heat and much of this is retained within the body of homeotherms by insulating layers of fat, feathers or fur. Dairy cattle, like other warmblooded animals, function most efficiently in environments where they can maintain their body temperature at around 38° C. Tissue and cellular metabolism and the underlying biochemical reactions that sustain life and productive functions need body temperature to be maintained within very narrow limits. Relatively small increases in body temperature result in the breakdown of body protein and a significant depression in production.

Climate change, particularly global warming has complex impacts on domestic animal production system affecting feed supply, challenging thermoregulatory mechanism resulting thermal stress, emerging new diseases due to change in epidemiology of diseases and causing many other indirect impacts. So, climate change will have farreaching consequences for dairy and meat production, especially in vulnerable parts of the world where it is vital for nutrition and livelihoods. Due to poor availability of good quality feed and fodders in India, animals are generally maintained on poor quality grasses available in the pastures or are stallfed, mainly on crop residues. India is already deficit in feed and fodder. These shortages would be further aggravated by the adverse effects of global warming on fodder crop production.

Bacterial diseases are a significant threat to human health, agriculture, and the environment. These diseases are caused by pathogenic bacteria that can infect various hosts, including humans, animals, and plants. The severity and spread of bacterial diseases are influenced by various factors, including weather parameters. Weather conditions, such as temperature, humidity, wind, and precipitation, play a crucial role in the development, dissemination, and survival of bacterial pathogens (Fig. 8.1). Fig. 8.1. Bacterial infection on soybean leaves Temperature, for instance, affects the growth and reproduction of bacteria, with optimal temperatures varying among different species. High temperatures can accelerate the growth of some bacteria, while low temperatures can slow it down or even kill them, however every pathogenic bacterium have its own weather window. For example, a daytime temperature of 35°C and nighttime temperatures of 27°C are most favorable for Xanthomonas oryzae infecting rice. Similarly, humidity influences the survival and dissemination of bacteria, with high humidity favoring the growth and spread of many bacterial pathogens. For example, lower soil moisture decreases the chances of infection of Ralstonia solanacearum in tomato plants. Wind and precipitation also impact the spread of bacterial diseases. Wind can disperse bacterial spores and cells, allowing them to reach new areas and infect new hosts. Precipitation, on the other hand, can influence the availability of moisture, which is essential for the growth and survival of many bacterial

Output of dairy products from animals, output from the poultry, goats, sheep, exotic birds, animal growth, their living environments and diseases affecting them, are known to be governed by weather conditions. Development of quantitative climate-animal relationships and efficient utilization of daily weather data for monitoring the various aspects, continues to be a significant research priority. Traditionally the major climatic factors on which attention has been focused are: temperature, humidity, solar radiation and length of day. The effects of these climatic elements on reaction of animal physiological parameters have been studied by measurements of (a) animal?s ability to prevent heat loss by such means as increased evaporative cooling from the body surface, (b) its ability to reduce heat production by lowering its metabolic rate through more efficient energy utilization (c) its ability to put up with a rise in body temperature or with the consequences of compensatory reactions. Experiments are usually done in climate chambers since field measurements often involve difficulties of interpretation in separating out the effects of climate from those of nutrition. Water consumption, water intake, insensible perspiration (diffusion moisture, different from the moisture which is actively secreted), protein intake, intra- and extra cellular volumes, plasma and blood volumes, body temperature, respiratory activity etc., of animals are all known to be affected in relation to changes in air temperature and humidity. Airflow also is an adjutant factor since it affects temperature and humidity. Significant seasonal changes have also been frequently recorded. These in turn, have profound effect on output of milk yield and several other animal products. Development of predictive techniques for assessment of milk yield or other products had been recognized as a thrust area, so as to develop suitable and viable strategies for storage; transport, marketing and distribution of several livestock products. Several gross relationships between climate and its influence on physiological and biochemical aspects of animal behaviour have been worked out in the past on seasonal basis but a more intensive study on short period stress effects on the output products in relation to prediction of output is the need of the hour. For pursuing research on these aspects, an appropriate understanding of the specific meaning and use of terminology such as ?thresholds?, ?optima?, ?normal?, ?extreme events? in more detail is considered appropriate. Methods of analysis also need to be addressed and evolved.

Agriculture is the backbone of human civilization, providing food, fiber, and livelihoods for billions of people around the world. Crop yields, which are a critical component of agricultural productivity, are influenced by a complex array of factors, including genetics, soil quality, water availability, and management practices. However, among these factors, weather and climate stand out as two of the most significant drivers of crop yields.
Weather and climate are intimately linked, with weather referring to short-term atmospheric conditions, such as temperature, precipitation, and wind, and climate describing the long-term average atmospheric conditions in a particular region. Together, they form a dynamic duo that shapes the fate of crops, influencing their growth, development, and productivity.
The impact of weather and climate on crop yields is multifaceted. Weather events, such as droughts, floods, and heat waves, can have devastating effects on crops, leading to reduced yields, lower quality produce, and even complete crop failures. Climate, on the other hand, influences the overall growing conditions, determining the suitability of a region for specific crops and the timing of planting, growth, and harvest.
Understanding the complex interplay between weather, climate, and crop yields is crucial for ensuring food security, improving agricultural productivity, and promoting sustainable farming practices. This chapter aims to explore the intricate relationships between weather, climate, and crop yields, examining the ways in which these factors interact and influence each other. By delving into the latest research and findings, this chapter will provide insights into the following key topics:
The impact of weather events, such as extreme temperatures, precipitation, and wind, on crop yields
• The influence of climate on crop growth, development, and productivity
• The role of climate change in altering weather patterns and crop yields
• Strategies for mitigating the negative impacts of weather and climate on crop yields, such as climate-smart agriculture and weather-based crop insurance

In climatology, terms “Weather” and “Climate” have different connotations. Weather refers to the state of atmosphere at any given time denoting the short- term variations of atmosphere in terms of temperature, pressure, wind, moisture, cloudiness, precipitation and visibility. Weather is highly variable. It is constantly changing, sometimes from hour to hour and at other times from day to day. The aforementioned properties of the atmosphere are subject to constant change and their state at any time determines the state of the weather. However, weather elements are not separate rather they are closely related with each other.

David I. Blumenstock, an eminent climatologist has defined the weather in more restrictive sense. According to him, weather is the behaviour of the lower atmosphere with particular emphasis on the atmospheric behaviour which affect the lands and oceans and have a marked influence on the organisms that live upon the lands, within the waters of the earth or in the lower air. For the geographer, this definition of weather is more satisfactory. Since, he is interested more in the working of the lower atmosphere which affects the life of man as well as natural environment directly. Thus, we come across a great many varieties of weather covering a wide range of conditions.

INTRODUCTION

Integrated Pest Management (IPM) has been defined as a “system that, in the context of the environment and the population dynamics of the pest species, utilizes all suitable techniques and methods in as compatible manner as possible that maintain the pest populations at levels below those causing economic injury” (Glass 1975). The Inter society Consortium for Plant Protection (ICPP) has defined integrated pest management as “the use of multiple tactics in a compatible manner to maintain pest population at levels below those causing economic injury while providing protection against hazards to humans, domestic animals, plants and the environment”. The term ’integrated’ means it is a broad interdisciplinary approach taken using scientific principles of plant protection of variety of management strategies and tactics to fuse into a single system. The terms ‘pest’ means all biotic agents which adversely affect plant production. This includes insects, mites, nematodes, weeds, bacteria, fungi, viruses, parasitic seed plants and vertebrates. The term ‘management’ indicates to keep the pest population below some level based on economic criteria. It does not mean complete eradication of entire pest population.

Many diseases, nematodes, insects and weeds affect crop production, causing severe yield loss. Weather is the most important factor that determines the geographical distribution of these crop pests. The local weather patterns have a significant impact on the abundance of diseases and insect pests in the crops. The severity of disease and pest development depends on the combination of weather conditions during the growing season and is variable from season to season. The weather conditions include temperature (both the maximum and the minimum), light, rain, humidity, dew, cloudiness, sunshine, wind, air currents, evaporation, snow and atmospheric pressure. However, among these weather parameters, temperature and humidity play the major roles in infection of crops due to insect pests and diseases.

Fungal diseases are a significant threat to crop health and productivity worldwide, causing substantial economic losses and compromising food security. The development and spread of fungal diseases are influenced by a complex array of factors, including crop susceptibility, pathogen virulence, and environmental conditions. Among these environmental factors, weather plays a critical role in determining the severity and impact of fungal diseases on crops. Weather conditions, such as temperature, humidity, precipitation, and wind, can significantly affect the life cycle of fungal pathogens, including spore production, dispersal, and infection. For example, high temperatures and dry conditions can inhibit the growth and development of some fungal pathogens, while cool and wet conditions can favor their development and spread. Similarly, wind and precipitation can facilitate the dispersal of fungal spores, leading to the rapid spread of disease (Fig. 7.1). Understanding the impact of weather on fungal diseases is essential for developing effective disease management strategies. By recognizing the weather conditions that favor or inhibit the development of fungal diseases, farmers and crop managers can take proactive measures to prevent or mitigate disease outbreaks. This may involve adjusting planting dates, irrigation schedules, and fungicide applications to minimize the risk of disease. Furthermore, knowledge of the weather effects on fungal diseases can also inform the development of more accurate and reliable disease forecasting systems.

Coffee is grown at higher elevation across the Western Ghats between 750 and 1200 m amsl. It requires a certain degree of shade for its better performance.  The annual rainfall over the coffee growing tracts varies between 1400 and 2600mm, having uni/bi-model rainfall with prolonged dryspell from November to May. It is more so over North of the Western Ghats. The mean annual maximum temperature varies between 24 and 300C while the minimum between 15 and 180C. The difference between maximum and minimum temperatures (temperature range) varies between 5 and 160C across the coffee tract. The ‘Monsooned Malabar Coffee’ is a specialty coffee produced from the erstwhile ‘Malabar Region’. It undergoes certain changes in physical and biochemical characters when the coffee beans are processed during the summer monsoon (June to September). It is processed at Mangalore, located in Coastal Karnataka. The processing location experiences heavy rainfall of more than 1000 mm in July, followed by 950 mm in June and 600 mm in August. Out of 3264 mm of annual rainfall, 2852 mm is received during the monsoon period. It accounts more than 80 per cent of annual rainfall. The maximum temperature during the coffee monsooning period varies between 28 and 30°C while night temperature revolves between 22 and 24°C. Being located in the tropics along the West Coast, the crop processing environment in terms of surface air temperature is relatively uniform and moderate with a characteristic feature of heavy clouds and continuous rainfall during the monsoon period. These monsoon features are more predominant from the middle of June to August during which the coffee beans are subjected to monsooning. The coffee beans
bulge in the process of monsooning and the volume increases significantly due to absorption of atmospheric moisture. It is directly related to the monsoonal wind during which coffee beans are processed. The bulging was less in all the samples processed during monsoon 2003, which varied from 2.1 to 2.7 ml/100 number, while it ranged between 2.7 and 5.8 ml/100 number in the samples processed during monsoon 2004.

Weather parameters, such as temperature, humidity, rainfall, and wind, play a significant role in the epidemiology of viral diseases in crops. Viral diseases, caused by viruses that infect plants, can have devastating effects on crop yields and quality, leading to significant economic losses for farmers and the agricultural industry. The impact of weather parameters on viral diseases is complex and multifaceted. Weather conditions can influence the spread of viruses, the survival and multiplication of virus vectors, and the susceptibility of plants to virus infection (Fig. 9.1). Understanding the relationships between weather parameters and viral diseases is essential for developing effective disease management strategies and mitigating the impacts of viral diseases on crop productivity. Fig. 9.1. Yellow Leaf Curl Viral disease of Tomato Temperature, for example, can affect the replication and transmission of viruses, with optimal temperatures varying depending on the specific virus, its vector and host plant. Humidity and rainfall can influence the spread of viruses by affecting the movement and behavior of virus vectors, such as insects and nematodes. Wind can also play a role in the spread of viruses by dispersing virusinfected pollen and insects. This chapter will explore the effects of weather parameters on viral diseases in crops, with a focus on the relationships between temperature, humidity, rainfall, wind, and viral disease epidemiology. By examining the complex interactions between weather parameters and viral diseases, we can gain a deeper understanding of the factors that contribute to the spread and impact of viral diseases in crops, and develop more effective strategies for managing these diseases.

Abstract

Under Ministry of Earth Sciences, India Meteorological Department has launched District level Agro-meteorological Advisory Services in June 2008. The agro-advisory bulletins containing the forecast on rainfall cloud cover, wind direction and speed aid minimum and maximum temperature with their likely impact on crops are in use twice in a week.

Agriculture has always played and will continue to play a dominant role in the growth of Indian economy in the foreseeable future. It represents the largest sector producing around 28 per cent of the gross domestic product (GDP). Achieving self sufficiency in food grains production has ensured a high priority for agricultural sector in the successive development plans of the country. Agricultural production is grossly affected by attack of pests/diseases on various crops and the losses in food grains only are to the tune of Rs 90,000 crores each year in India. The prevention of such losses needs substantial consideration and accordingly forewarning of pests and diseases is essential for taking timely control measures. These are also required for assessing losses. Pest/disease infestation in crops is highly influenced by meteorological factors. The weather based modeling for early warning of pest/disease infestation may provide appropriate tool for investigating and predicting pest/disease status.

Under normal weather situation, agriculture depends on timely occurrence of rainfall for crop management activities irrespective of different farming situations namely, irrigated and unirrigated agriculture. Changes in temperature and rainfall pattern together with frequent occurrence of extreme weather events are major anticipated threats from the climate change that occurs now around the world. This threat in long run, if not addressed properly, would affect food security of a country. Pratap Narain et al., (2000) observed an increase in moderate and severe drought occurrence numbers in the arid zone of India during last decade (1991-2000) as compared to the earlier decades of the last century. Similarly, Pasupalak (2008) reported daily maximum rainfall of 400.3 mm in the last decade against earlier record of 256.4 mm (1969–78) in a location at Odisha State. Further the inter- annual variation within the decade did increase and also the number of rainy days with very heavy rainfall > 125 mm also found increased in the location against the daily mean rainfall of 20 mm/day in India.

A day may be with heavy rainfall or with bright sunshine or windy or in combination of these. When heavy rainfall continues for more than a week with some system like cyclone, floods may be the result. Similarly, if dry spell continues during a cropping season for more than 15 days, drought would initiate in that region. This is again depending upon the nature of the soil water holding capacity and nature of soils, topography and green cover of that region. In between these two extremes, we have normal season, where we get normal seasonal rainfall during a cropping season. Hence like dress code, in agro-climatology, there are three weather codes, namely floods code, drought code and normal code. The jargon weather code was developed by Dr.M. S Swaminathan in India. Across the countries of the World, if these weather codes occur, the impact would be universal. The strength of adaptation capacity to maneuver these extreme events by the farming community rests with their past experience made for similar situations, financial support and also the technology options that are available from the scientific institutions.

In the preceding chapters, we embarked on a comprehensive journey through the realm of vegetables, covering a wide range of species that belong to different botanical and culinary groups. These chapters provided an indepth exploration of the characteristics, growth habits, and environmental requirements of various vegetables, as well as the effects of weather conditions on their productivity.
However, the diversity of vegetables is vast, and there are several other important species that were not covered in the earlier chapters. These vegetables may be regionally specific, possess unique characteristics, or have distinct environmental requirements. Despite their importance, they have remained outside the scope of our previous discussions.
This chapter aims to fill this knowledge gap by providing an overview of these additional vegetables, with a focus on understanding the impact of weather conditions on their growth, development, and productivity. By examining the effects of temperature, moisture, light, and other environmental factors on these vegetables, we can gain valuable insights into their cultivation requirements and optimize their production.
Through this chapter, we hope to provide a more comprehensive understanding of the vegetable kingdom, highlighting the diversity of species, their environmental requirements, and the strategies for maximizing their yields. By expanding our knowledge of these lesser-covered vegetables, we can promote their cultivation, conservation, and sustainable use, ultimately contributing to global food security and nutrition.

One of biggest challenges facing animal science is to increase the production in the context of climate change. Animal performance may be limited by adverse climatic focus (Sejian et al., 2010; Sejian et al., 2012). The economic impact of climate changes in relation to livestock production are widely reported, and several losses are predicted if current management systems are not modified to reflect the shift in climate. Climate change poses formidable challenge to the development of livestock sector in India (Sejian et al., 2013; Naqvi et al., 2013). Global warming could increase water, shelter and energy requirement of livestock for meeting projected milk demands. The anticipated rise in temperature between 2.3 and 4.8°C over the entire country together with increased precipitation resulting from climate change is likely to aggravate the heat stress in dairy animals, adversely affecting their productive and reproductive performance, and hence reducing the total area where high yielding dairy cattle can be economically reared. A preliminary estimate indicates that global warming is likely to lead to a loss of 1.6 million tonnes in milk production in India by 2020.

Seasonal variations in climatic conditions impact the availability of feed in the livestock (Sejian et al., 2014; Bagath et al., 2016). Over and above the effect of seasonal variations that cause considerable economic hardship, it is the unforeseen and unexpected periods of inclement and severe weather conditions which exacerbate the gross economic losses in livestock industry (Sejian and Srivastava, 2010; Sejian et al., 2010). In addition to mortalities of livestock associated with severe climatic conditions, reductions in reproductive and productive performances generate sizeable economic setback. Impressive advances in research have been made to assess the impact of climatic stressors on the physiological and dynamic responses of livestock (Shaji et al., 2015; Maurya et al., 2015). At the same time livestock managers and farmers continue to search for management options which can alleviate and reduce the effects of severe weather on livestock performance and productivity. This chapter will address in detail the impact of environmental stresses on livestock production and reproduction. These attempts will help the scientific fraternity to develop appropriate mitigation strategies to improve ruminant livestock production in these agro-ecological zones. This might pave way to improve the livelihood securities of poor and marginal farmers of this tropical environment via an appropriate universal research agenda.

4.1 Introduction

The livestock/poultry have great capability for climatic adaptation and acclimatization. However in an open environmental condition their overall well-being and efficiency depends on day-to- day weather conditions. While certain breeds of livestock and poultry are considerably flexible to adjust themselves with the varying weather conditions, the others may have little adjustability. This has led to the development of weather/climate based livestock/ poultry management practices which include the general care. Nutrition and health managements for optimizing conditions for best yield in respect of milk, meat, eggs, wool, load carrying capacity etc. have been properly documented. 

ABSTRACT

Losses and benefits in agricultural production are associated with various weather parameters. So prediction of weather systems in different spatial and temporal scale over the Indian region therefore assumes considerable socio-economic importance. Meteorological information also plays an important role in the following operations in agriculture. The meteorological services can help the farmers & the planners exploit the potential of good weather and minimize the impact of bad weather as there exist tremendous opportunities for applications of meteorology in both day to day and long term planning in agriculture and such applications could contribute substantially to promote sustainable agriculture and poverty alleviation and the management of agrometeorological data is the key to these applications. Therefore, the area and input intensive agriculture is leading us into an era of unsustainable agricultural growth as the crucial components of sustainable agricultural production and distribution system such as integration of natural biological cycles and controls; protection and renewal of soil fertility and the natural resource base; optimization of the use of nonrenewable resources and of on-farm & off- farm inputs; ensuring dependable farm income. Hence, the meteorological information may help the farmer make the most efficient use of natural resources, with the aim of improving agricultural production both in quantity and quality. It becomes more and more important to supply meteorological information blended with weather sensitive management operations before the start of cropping season in order to adapt the agricultural system to increased weather variability. Subsequent to this, weather forecast based Agro-meteorological advisories become vital to stabilize their yields through management of agro-climatic resources as well as other inputs such as irrigation, fertilizer and pesticides. The main emphasis of the existing AAS system is to collect and organize climate/weather, soil and crop information, and to amalgamate them with weather forecast to assist farmers in taking management decisions. This has helped to develop and apply operational tools to manage weather related uncertainties through agro-meteorological applications for efficient agriculture in rapidly changing environments. Hence, weather information and advisories have assumed greater significance under the increased variability in the changing climate. Thus, Weather forecasting and advisory has become an indispensable aid for sustainable agro-transformation

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Forecasts based on temperature and precipitation is important to agriculture. Agricultural production is highly dependent on weather, climate and water availability, and is adversely affected by weather and climate related disasters. In many developing countries where rainfed agriculture is the norm, a good rainy season means good crop production, enhanced food security and a healthy economy. Farming in many parts of the world, especially in the arid and semiarid regions is risky, because climate is highly variable. A timely seasonal forecast of favourable conditions could permit farmers to adjust cropping patterns and input use in order to benefit fully from these conditions. Under rainfed conditions, even a less reliable, but earlier forecast may be more valuable than an accurate but late forecast.

In about 340 B.C., Aristotle described weather patterns in Meteorologica. Later, Theophrastus compiled a book on weather forecasting, called the Book of Signs. Ancient weather forecasting methods usually relied on observed patterns of events. This experience was accumulated over the generations to produce weather knowledge. However, not all of these predictions prove reliable, and many of them have since been found not to stand up to rigorous statistical testing. Two officers from of British Royal Navy, Francis Beaufort and Robert FitzRoy formed the basis for all of today’s weather forecasting knowledge by middle of 19th century. A terrible storm in 1859 inspired FitzRoy to develop charts to allow predictions to be made, which he called ‘forecasting the weather’, thus coining the term ‘weather forecast’. The ‘Weather Book’ which FitzRoy published in 1863 was far in advance of the scientific opinion of the time. By the early 20th century, scientists had begun to believe that weather forecasting could be predicted based on mathematical methods. Computers were first used to create surface analyses in 1992 and by 1998 digital imagery were used for satellite, radar and surface observations, encompassing nearly every factor of weather interpretation. Modern technology, particularly computers and weather satellites, and the availability of data provided by coordinated meteorological observing networks, has resulted in enormous improvements in the accuracy of weather forecasting.

The sole science of meteorology is to deal with weather forecasting while livestock advisory based on weather forewarning is dealt with multidisciplinary approach in the field of livestock meteorology for the benefit of the livestock farmers. In this context, the current status of livestock advisory based on medium range weather forecasting is highlighted so that the tools for livestock advisory can be initiated and developed by the concerned for the benefit of livestock farmers in similar lines. Information on weather forecasting is used in various society linked sectors and animal husbandry component is one of them (Fig. 17.1).

Environment in which crops are grown dictates their final yield. Of these environmental factors, climate and weather the uncontrolable factors, have maximum influence on crop productivity. Vagaries of weather subject a crop to different ecological situations from year to year leading to differential responses of crops to input resources. This situation limits the use of costly inputs for realizing optimum yield. While weather itself cannot modify, the hazardous weather can often be mitigated by agronomic management. Therefore, the primary requirement for initiating agronomic measures against weather hazards is foreknowledge of weather situation that is likely to develop in an area.

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Weather forecasts are made by collecting quantitative data about the past and current state of the atmosphere on a given place and using scientific understanding of atmospheric processes to project how the atmosphere will evolve on that place. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation is important to agriculture.

Agricultural production is highly dependent on weather, climate and water availability, and is adversely affected by weather and climate related disasters. In many developing countries where rainfed agriculture is the norm, a good rainy season means good crop production, enhanced food security and a healthy economy. Failure of rains and occurrence of natural disasters such as floods and droughts can lead to crop failures, food insecurity, famine, loss of property and life, mass migration, and negative national economic growth (Sivakumar, 2006).

Farming in many parts of the world, especially in the arid and semiarid regions is risky, because climate is highly variable. In some developing countries as much as 80% of the variability in agricultural production is due to the variability in weather conditions. This production variability in agriculture has immediate and important macroeconomic impacts. A timely seasonal forecast of favourable conditions could permit farmers to adjust cropping patterns and input use in order to benefit fully from these conditions. Also, a timely forecast could give the marketing system and downstream users, such as the food processing industry, time to prepare for a bountiful harvest (Arndt et al., 2000). It is important to remember that under rainfed conditions, even a less reliable, but earlier forecast may be more valuable than an accurate but late forecast (Mjelde et al., 1998).

Introduction 
Weather forecasting stands as a testament to humanity’s enduring quest to understand and anticipate the natural world. Far from being a mere casual prediction, it is a highly sophisticated scientific and technological discipline dedicated to projecting the future state of the Earth’s atmosphere for specific locations and times. This complex endeavor begins with the meticulous collection of vast quantities of real-time data, encompassing everything from surface observations of temperature, pressure, wind, and humidity to upperair measurements gathered by weather balloons, aircraft, radar, and advanced satellite systems. The core of modern weather forecasting lies in numerical weather prediction (NWP) models. These are intricate computer programs that embody the fundamental laws of physics governing atmospheric processes, such as fluid dynamics and thermodynamics. By feeding the enormous datasets of current atmospheric conditions into these models, supercomputers solve complex equations to simulate how the atmosphere will evolve over minutes, hours, and days. The raw output from these models is then further refined by human meteorologists who apply their expertise, integrating local geographical influences, historical patterns (climatology), and statistical techniques to produce the most accurate and actionable forecasts. The importance of accurate weather forecasting cannot be overstated. It serves as a vital tool across countless sectors, guiding daily personal decisions, from what to wear to whether to carry an umbrella. Crucially, for agriculture, precise weather forecasts are indispensable. Farmers rely heavily on these predictions to make informed decisions that directly impact crop yield and livestock health. Knowing when to plant seeds, schedule irrigation, apply fertilizers and pesticides, or harvest crops is directly influenced by anticipated rainfall, temperature extremes, and wind conditions. Timely warnings of frost, hailstorms, or prolonged droughts can enable farmers to take protective measures, minimizing losses and ensuring food security. For example, in regions like Telangana, where agriculture is a dominant sector, understanding

Weather forecasts play a crucial role in disease control measures for crops. By providing advance warning of favorable conditions for disease outbreaks, weather forecasts enable farmers to take proactive measures to prevent or mitigate the impact of diseases on their crops. This approach is particularly important in modern agriculture, where crop diseases can have devastating effects on yields and quality. The relationship between weather conditions and crop diseases is complex, with factors such as temperature, humidity, rainfall, and wind direction all playing a role in the development and spread of diseases. For example, high humidity and rainfall can create ideal conditions for fungal diseases, while warm temperatures and dry conditions can favor the development of bacterial diseases.By analyzing weather forecasts, farmers can identify periods of high disease risk and take steps to protect their crops. This might involve applying fungicides or bactericides, adjusting irrigation schedules, or implementing other cultural controls to reduce the risk of disease outbreaks (Fig. 12.1). In recent years, advances in technology have improved the accuracy and availability of weather forecasts, making it easier for farmers to access the information they need to make informed decisions about disease control.Additionally, the development of predictive models that incorporate weather data, crop phenology, and other factors has further enhanced the ability of farmers to anticipate and manage disease outbreaks . Overall, the use of weather forecasts in disease control measures is a critical component of integrated disease management (IDM) strategies, which aim to minimize the economic, environmental, and social impacts of crop diseases. By leveraging advances in weather forecasting and predictive modeling, farmers can reduce their reliance on chemical controls, promote more sustainable agricultural practices, and improve the overall health and productivity of their crops.

A weather hazard is an extreme weather event that threatens people or property. There are various weather hazards that affect agricultural productions. These hazards vary from one climatic zone to another and occur at different times, although some regions are more vulnerable to certain hazards than other. These weather hazards depend on the latitude of the place on the world map. These hazards affect crops and agricultural productivity negatively if they are not checked. Every agricultural zone has one particular hazard that is associated with it and in most cases affects the crop productions and reduces the annual crop yield. Weather hazards include cyclones, droughts, f loods, hailstorms, heat-waves and cold-waves.

The hazard is distinguished from an extreme event and a disaster. An extreme event is simply an unusual event; it does not necessarily cause harm. A disaster is an event that does cause harm in significant amounts. Weather hazards are often called as natural hazards. The natural hazards become natural disasters when people’s lives and livelihoods are destroyed.

Hydrologic hazards are the result of either excess or a severe lack of water, i.e., flood or drought. Hydrometeorological hazard is a process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage. Human and material losses caused by natural disasters are a major obstacle to sustainable development. By issuing accurate forecasts and warnings in a form that is readily understood and by educating people about how to prepare against such hazards, before they become disasters, lives and property can be protected.

DROUGHT

Drought is a relative term used with reference to deficiency of rainfall when compared to normal rainfall of a given location. However, drought cannot be defined in terms of amount of rainfall or number of days without rain. Since ancient times droughts have had far-reaching effects on humankind by causing the failure of crops, decreasing natural vegetation, and depleting water supplies. Drought is different from other hazards; in that it develops slowly. It is a hazard that requires many months to emerge and that may persist for many months or years thereafter. This type of hazard is known as a ‘creeping’ hazard. Generally, this occurs when a region receives consistently below average precipitation.

Weather, while often benign and essential for life, can also manifest in powerful and destructive forms, posing significant threats to human life, property, and the environment. This chapter, “Weather Hazards,” will delve into the detailed nature of these potentially dangerous atmospheric phenomena.
We will explore a range of significant weather hazards, including severe storms such as thunderstorms, tornadoes, and hailstorms, which can bring intense winds, torrential rainfall, and damaging projectiles. We will also examine the characteristics and impacts of tropical cyclones (hurricanes, typhoons), known for their devastating winds, storm surges, and widespread flooding. Furthermore, we will discuss the dangers associated with extreme temperature events, including heat waves, characterized by prolonged periods of excessively hot weather, and cold waves, marked by extended periods of dangerously cold temperatures. We will also cover the challenges posed by heavy snowfall, blizzards, and ice storms.
For each hazard, we will investigate the meteorological conditions that lead to its development, the typical characteristics and intensity scales  used to classifyit, and the primary impacts it can have on society and the natural world. Understanding the formation, behavior, and potential consequences of these weather hazards is crucial for effective forecasting, issuing timely warnings, and implementing mitigation strategies to enhance safety and resilience.
Join us as we embark on a detailed exploration of the forces of nature that can transform familiar weather into formidable hazards.

In today’s rapidly evolving world, food production is at the confluence of tradition and innovation. While age-old farming practices have sustained civilizations for millennia, the modern era demands an unprecedented level of precision and foresight. Weather intelligence—the practice of integrating detailed meteorological data with advanced analytics and decision support systems— is revolutionizing food production, from agriculture and fisheries to animal husbandry (Fig. 1.1). This chapter lays the foundation for understanding how accurate and timely weather data underpins food security, economic sustainability, and environmental stewardship. It further highlights global themes addressing the growing demand for food in any nation with a burgeoning population, the challenges of climate change, and the increasing frequency of extreme weather events. This introduction also outlines the objectives and structure of this book, which aims to empower decision makers with the knowledge needed to navigate a world where climate and food production are inextricably linked.
1.1 Context & Importance
1.1.1 The Changing Face of Food Production
Food production has always been sensitive to the whims of nature. Historically, farmers relied on folklore, seasonal patterns, and local wisdom to guide planting and harvesting cycles. With growth and development of atmospheric sciences from 19th century, farmers started depending upon weather forecasts in planning and management of agricultural production systems. However, with the advent of climate change, environmental degradation, and increasingly unpredictable

The global economy has adversely been affected to a considerable extent due to weather related disasters like droughts, floods, heat waves and cold waves which are not uncommon in the recent past due to global warming and climate change. For the first time, the year 1998 was declared as the weather related disastrous year globally. The year 2015 was the warmest year globally, again. Such weather phenomenon of warming more and more year after year was noticed in the current decade as well when we look at 2023 and 2024. The year 2010 was the warmest year ever recorded, followed by 2009 in India. The occurrence of floods and droughts, cold and heat waves adversely affected the Indian foodgrains production to a large extent across the Country in one or other region as seen in 2014, 2012, 2009, 2004, 2002 and 1987. The cold wave in winter 2003- 04 across the Northeast region of the Country and the heat wave in summer 2004 across the same region are still in memory to understand the ill effects in agriculture/horticulture/poultry/inland fisheries sectors. Model simulations
indicate that a marked increase in rainfall and temperature over India would be seen during the current century. The maximum expected increase in rainfall is likely to be 10–30% over the Central India. Temperatures are likely to increase between 2 and 30Cby the end of 2100 A.D. However, steps taken towards the green energy across the world may yield results not to allow atmospheric global temperature beyond 1.5 to 20C. Greater number of high surges and increased occurrence of cyclones in post monsoon period along with increased maximum wind speed are also expected along the East Coast of the Country. The summer droughts and heavy rains leading to waterlogging, floods and landslides during the monsoon period is a threat to plantation crops which are predominantly grown in the Humid Tropics like Kerala (8°15` N and 12°50`N latitudes and between 74°50`E and 77°30`E longitudes).

Forecasting crop diseases based on the movement of weather systems is a critical component of modern agriculture, enabling farmers and agricultural stakeholders to take proactive measures to prevent or mitigate the impact of disease outbreaks on crop yields and quality. The relationship between weather patterns and crop disease transmission is complex and multifaceted, with various weather factors influencing the development, spread, and severity of crop diseases. (Fig. 14.1). Weather systems, including high and low-pressure systems, fronts, and wind patterns, play a significant role in the spread of crop diseases. For instance, wind currents can transport fungal s3pores, bacteria, and viruses over long distances, facilitating the spread of diseases such as powdery mildew, rust, and leaf spot. Additionally, weather conditions like temperature, humidity, and precipitation can affect the growth and development of crops, making them more susceptible to disease. Recent advances in meteorology, plant pathology, and data analytics have enabled researchers to develop predictive models that can forecast crop disease outbreaks based on weather patterns. These models use historical weather data, disease surveillance data, and crop phenology data to identify patterns and correlations between weather systems and disease outbreaks.

Introduction

Climate change has brought about unprecedented weather variability, disrupting established patterns and posing significant challenges to global agriculture. The Intergovernmental Panel on Climate Change (IPCC) reports unequivocal evidence of increasing temperatures and altered precipitation patterns (IPCC, 2021). These changes impact crop production, water availability, and overall food security, necessitating innovative approaches to ensure sustainable agriculture in the face of evolving climatic conditions. To address these challenges, accurate crop yield forecasting becomes paramount. Reliable predictions empower farmers, policymakers, and agricultural stakeholders to make informed decisions regarding resource allocation, risk management, and adaptation strategies (Lobell et al., 2012; FAO, 2019). This chapter explores the intricate interplay between weather variability, climate change, and the development of effective crop yield forecasting models, offering a comprehensive perspective on how sustainable agriculture can be achieved in the midst of these dynamic environmental shifts.

Weather wisdom refers to the ability to understand, interpret, and apply knowledge of weather patterns, forecasts, and conditions to make informed decisions in various aspects of life. This concept encompasses a comprehensive understanding of meteorological principles, as well as the ability to analyze and apply weather information in a practical and effective manner. At its core, weather wisdom involves a grasp of basic meteorological concepts, such as atmospheric pressure, temperature, humidity, wind, and precipitation. This foundational knowledge serves as a framework for understanding more complex weather phenomena, such as storms, droughts, and heat waves.In addition to a solid understanding of weather fundamentals, weather wisdom also requires the ability to interpret forecasts, warnings, and advisories issued by meteorological agencies. This involves being able to comprehend and analyze weather forecast models, as well as understanding the limitations and uncertainties associated with weather prediction (Fig. 2.1). Furthermore, weather wisdom involves familiarity with local weather patterns, climate, and microclimates. This knowledge is essential for making informed decisions, as local weather conditions can vary significantly from regional or national forecasts. The application of weather knowledge is a critical component of weather wisdom. This involves being able to apply weather information to various aspects
