Types of Biomedical Waste

1. Infectious waste: waste contaminated with blood and other bodily fluids (e.g. from discarded diagnostic samples), cultures and stocks of infectious agents from laboratory work (e.g. waste from autopsies and infected animals from laboratories), or waste from patients with infections (e.g. swabs, bandages and disposable medical devices)

2. Pathological waste: human tissues, organs or fluids, body parts and contaminated animal dead bodies

13.1 Introduction
Since the United Nations Framework Convention on Climate Change was founded in 1992, efforts have been undertaken to address climate change, which is today a serious problem for the entire globe. These programmes made an effort to lessen GHG emissions and lessen the effects of climate change. There have been a number of significant accords made, including the Kyoto Protocol in 1997, the Copenhagen Accord in 2009, and the Paris Agreement in 2015. Despite these accords, the Intergovernmental Panel on Climate Change (IPCC)’s most recent assessment contends that current decarbonization efforts fall short of the goal of keeping global temperature increases to 1.5°C over pre-industrial levels by 2050. Instead, it is anticipated that the temperature will have increased to 2.7°C by 2050 (Anonymous 2021). Analysing how climate change is affecting this sector of the economy is crucial. Fruit production is significantly hampered by changing precipitation patterns, rising temperatures, and extreme weather events. The growth, development, and production of fruit crops may be impacted by these changes, which could lead to financial losses and problems with food security. Improved methods and technologies for fruit production must be used to address these problems and comply with the objective of limiting the increase in global temperature. Adopting sustainable farming methods, bolstering water management systems, investing in crop varieties resistant to climate change, and improving postharvest storage and transportation technology may all be necessary to achieve this. Additionally, strengthening agroforestry systems and safeguarding biodiversity can support the fruit industry’s attempts to adapt to and mitigate climate change. Additionally, in order to lessen the effects of climate change on fruit agriculture, international collaboration and cooperation are essential for the adoption of suitable policies as well as the exchange of knowledge and resources. One example is encouraging collaborations between governments, agricultural organisations, researchers, and farmers to create and implement climate-smart practises and technologies. It is important to support various carbon capture and storage (CCS) technology that can remove CO2 from the atmosphere or prevent its release in order to fulfil the Sustainable Development

Insecticide based plant protection in India as well as in the world resulted in wide variety of environmental and health issues. Insecticides although gave satisfactory control of target pests initially, have posed serious issues such as resistance, resurgence and residue and also contamination of water bodies, food chain leading serious ill effects in humans, mammals, soil beneficial microbiota etc. After thorough examination of scientific evidences and facts on ill effects of synthetic organic insecticides, much emphasis was given for biological control including parasitoids, predators, entomopathogens, biopesticides, microbial control etc. in order to overcome above ill effects.

Horticulture, the branch of agriculture that deals with the art, science, technology, and business of cultivating plants, plays a vital role in food security, nutrition, and economic development globally. This diverse sector encompasses a wide array of activities, broadly categorized into:
• Pomology: The cultivation of fruits and nuts.
• Olericulture: The cultivation of vegetables.
• Floriculture: The cultivation of ornamental flowering plants.
• Landscape Horticulture: The design, construction, and maintenance of landscapes.
• Post-harvest Handling: The management of horticultural produce after harvest to maintain quality and reduce losses.
Each of these components is intricately linked with weather conditions, making the horticulture sector highly vulnerable to climate change.

Climate change is a complex problem involving varied interactions between the environment, natural resources (land, crops, animals and water) and people. These interactions are likely to change the ecological and agricultural landscape, and therefore influence agricultural and animal production. The Intergovernmental Panel on Climate Change (IPCC) has dictated that global warming/climate change could lead to many environmental problems i.e., Drought, floods, crop and animal farming, food production, and health hazards etc. Agriculture is closely dependent on the endowment of natural resources and environmental conditions of soil and climate. India is divided into many agro—climatic zones depending upon rainfall, agriculture and soil fertility. The agro climatic conditions of India and the various other factors that largely determine the cropping patterns vary throughout the country. Warangal district falls into two agro climatic regions namely Southern Telangana Zone and North Telangana Zone.

Introduction

Climate change and agriculture are interrelated issues, both of which take place on a global scale. Global warming is projected to have significant impacts on conditions affecting agriculture, including fluctuation of temperature, carbon dioxide, glacial run-off, precipitation and the interaction of these factors (Sehgal et al., 2006; Kalra et al., 2008). These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and for domesticated animals. The overall effect of climate change on agriculture will depend on the balance of these effects. Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. Droughts, which have frequented different parts of India through the history, have been responsible for many famines, rural poverty and migration despite development of impressive irrigation potentials. Similarly, abnormal temperatures, high velocity winds and humidity during critical stages are known to significantly affect crop growth and development, pest incidences and epidemics, demand on irrigation resources and finally food production. Over the past few decades, the main-induced changes in the climate of the earth due to multifarious human activities linked to develop have become the focus of scientific and social attention. The predicted changes to agriculture vary greatly by region and crop. Findings for wheat and rice are reported here: The study found that increase in temperature (by about 2 ºC) reduces potential grain yield in most places. Regions with higher potential productivity (such as northern India) were relatively less impacted by climate change than areas with lower potential productivity (the reduction in yields was much smaller). Climate change is also predicted to lead to boundary changes in areas suitable for growing certain crops. (Kalra et al., 2002-2003). Reduction in yields as a result of climate change is predicted to be more pronounced for rainfed crops (as opposed to irrigated crops) and under limited water supply situations because there are no coping mechanisms for rainfall variability. The difference in yield is influenced by baseline climate. In sub-tropical environments, the decrease in potential wheat yield ranged from 1.5 to 5.8%, while in tropical areas the decrease was relatively higher, suggesting that warmer regions can expect greater crop losses.

Global warming has become a worldwide concern after feeling the rise of temperature much more clearly after 1990. Global warming has negatively affected agricultural production throughout the world attributed by the climate change parameters. Effects of climate change on horticultural crops reported nowadays include problems of biotic and abiotic stress, yield loss, quality loss, etc. To understand the impact of climate change problems in horticulture, it is prerequisite to comprehend the issues related to global carbon cycle, climate change phenomenon, relationship between climate change variables and direct as well as indirect climate change effects.

Agriculture is dependent directly on weather and indirectly on the consequences of climate change. Changes in temperature, precipitation, incoming solar radiation and CO2 concentration are expected to impact crop growth to a greater extent. The overall impact of climate change on worldwide food production is considered to be low to moderate only when there is successful adaptation strategies towards climate change (IPCC, 1998). Global agricultural production could be benefited by the doubling CO2 concentration. All sectors including agriculture will be impacted by the adverse effect of climate change imposed on water resources (Gautam and Kumar, 2007; Gautam, 2009). India is expected to face more seasonal variation in temperature with more warming in the winters than summers (Christensen et al., 2007; Cruz et al., 2007). The frequency of drought occurrence is increasing due to variations in the monsoonal rainfall. Climate change is posing a great threat to agriculture and food security. Water is the most critical agricultural input in India, as 55% of the total cultivated areas do not have irrigation facilities.

Even with the variations in climate conditions, food accessibility for the present generation is assured, but as far as the future is concerned there is still the uncertainity of agricultural production. All climate models predict that there will be more extreme weather conditions, with more droughts, heavy rainfall and storms in agricultural production regions. Such extreme weather events will inf luence pest and disease occurance, imposing severe risks of crop failure. In India, climate change could be a potential threat towards food security due to population growth, industrialization and economic development. India’s climate could become warmer under conditions of increased atmospheric carbon dioxide.

1. Introduction

Uttarakhand is extremely vulnerableto climate-related changes due to its varied geography and rich glacier mass. The relationship between climate change and agriculture is not a new phenomenon. In the last 50 years, there has been a lot of academic focus on dealing with climate change issues in agriculture. Climate change is believed to affect agriculture by inducing changes in farmer’s behaviour, quantity, quality, cost of production, changes in production, consumption, prices & trade patterns; changes in market responses at global & local levels and these changes not only depend on the domestic and international adaptive capacity their economic impacts also vary by region, by sector, and by stakeholders’ groups. Climate change is a major global environmental problem and also an issue of great concern to all countries, irrespective of their size or level of development. It is established that adverse impacts are likely from increased frequency of extreme weather, floods & droughts, and submergence of coastal areas due to sea level rise and extreme climate variability. It is considered that mountain regions are vulnerable to climate change & it will have direct impacts on livelihoods as most of the economic & livelihood sectors are vulnerable to the effects of climate change.

Introduction
Climate change refers to alterations in the earth's global or regional climates over time, encompassing shifts in atmospheric variability or average conditions over periods ranging from decades to millions of years. The United Nations Framework Convention on Climate Change (UNFCCC) differentiates between "climate change" for human-induced alterations and "climate variability" for other changes. Over the past century, ending in 2005, the average global air temperature near the earth's surface has risen at an estimated rate of 0.74 ± 0.18°C (1.33 ± 0.32°F) (IPCC, 2007). In contemporary discussions, especially within environmental policy, "climate change" often refers to recent climate alterations. Both natural processes and human activities influence the earth's temperature and subsequent climate change. Significant increases in global anthropogenic greenhouse gas (GHG) emissions over the years have been major contributors to global warming. The sun, the earth's primary energy source, has a nearly constant output, but minor variations over extended periods can lead to climate change. Natural processes such as orbital changes (orbital forcing), volcanic eruptions, and greenhouse gas concentrations in the atmosphere also affect the earth's climate. Changes in atmospheric concentrations of greenhouse gases and aerosols, land cover, and solar radiation modify the climate system's energy balance, leading to either warming or cooling.
Volcanic eruptions release several gases, notably sulfur dioxide (SO2), which forms sulfate aerosols (SO4) in the atmosphere. Although linking specific weather events to global warming is challenging, increased global temperatures can result in broader changes like glacial retreat, Arctic shrinkage, and rising sea levels worldwide. Variations in precipitation patterns could lead to floods and droughts. Other impacts may include shifts in agricultural yields, the creation of new trade routes, reduced summer stream flows, species extinctions, and the spread of disease vectors. Most global climate change models predict a decline in snowpack on many western mountain ranges, adversely affecting fish populations, hydropower, water recreation, and water availability for agricultural, industrial, and residential use. Partial loss of polar ice sheets could lead to significant sea level rise, altering coastlines and inundating low-lying areas, with the most significant effects on river deltas and low-lying islands. These changes are projected over millennial timescales, but rapid sea level rise within centuries cannot be ruled out. Current climate change models predict a rise in sea surface temperatures between 2 °C and 5 °C by 2100 (IPCC Third Assessment Report, 2001; Done et al., 2003). According to the climate profile document of Jammu and Kashmir, the region has seen an increase in average temperature, with the Kashmir valley rising by 1.45°C and the Jammu region

Abstract

Aquaculture is facing the serious effects of climate change in the form of scarcity of water and shift in dissolved oxygen level leading to outbreak of diseases. In a study conducted in Farm facilities of ICAR, Tripura it was seen that rise in temperature do have significant effect on hematological and biochemical parameters of fish which are basic index of good health of any organism. Many different diseases occur in the farmers’ pond and which can be controlled. So some basic diseases and their controlling strategies have been pointed out that can lead to better management of fish diseases in pond condition.

Introduction

Seasonal or annual fluctuation in weather patterns is termed as climate variability. However, climate change is a change in the mean state of weather statistic over three decades of time period. Climate change is exacerbating the challenges faced by the agriculture as well as horticulture sector. For last 10 years, Asia is facing the serious threats from climate change and variability such as tsunami, f loods and droughts. Extreme events are expected to have large negative impacts on crop productivity. The rise in temperature and reduction in rainfall under semi-arid environments are likely to reduce production of fruits, vegetables and flowers in the coming 20 years. The production and quality of fresh fruit and vegetable crops can be directly and indirectly affected by exposure to high temperatures and elevated levels of carbon dioxide and ozone. The rise in atmospheric CO2 levels due to global climate change and horticultural practices has both direct and indirect effects on secondary metabolite synthesis in plants.

Introducton

The Working Group Report of Fifth Assessment Report 2013, by UN’s Inter governmental Panel on Climate Change (IPCC) says, that to limit warming to a rise of 2ºC above pre industrial levels, 1000 gigatones (trillion tons) is the upper limit of CO₂ that can be emitted. However, by 2011, we have already emitted 531 gigatones since last 260 yrs and in next 25 years, we will cross 1000 gigatones limit. There is a clear long-term global warming trend. Notably, the 20 warmest years have all occurred since 1981, and the 10 warmest have all occurred in the past 12 years.

ABSTRACT

Among the challenges of 21^st century, to make the food supply sustainable, the impact of climate change is largely unconceivable. The climate on earth has increased by 0.74° C over the past 100 years. Best estimate for low scenario of global warming is 1.8°C and for high scenario is 4°C. Last decade recorded the hottest in the century and 2009 has been rated hottest since 1900. Retreating glaciers have been confirmed in various parts of the world. Further, the current greatest challenge is to perceive the biological impact of such climate changes. Efforts have been initiated by Intergovernmental Panel on Climate Change (IPCC) to assess the impact of climate change on biological systems across the globe. Since 1950’s, the change in carbon dioxide content in the atmosphere is being monitored. Almost a decade later, computer models were employed to assess the possible impact of change in temperature and enhanced CO₂. By the 1980’s consensus was almost achieved on possible doubling of atmospheric CO₂ concentration due to emission from fossil fuels and rise in the global temperature. Since then quantitative estimates on the biological impacts of climate change have been taken up by scientific community world wide. Presently, ample of evidence on impact of climate change from marine to terrestrial environment, from species to communities, ecosystems and hierarchies have been gathered for both flora and fauna (Walther et al., 2002I). Parmesan and Yune (2003) reported that meta-analyses of 334 species and global analyses of 1,570 species revealed highly significant and regular patterns of change in relation to observed warming with more than 95 per cent confidence, as fingerprints of climate change.

Introduction

Climate change refers to change of weather variables over a long period of time. The Inter-Governmental Panel on Climate Change (IPCC) defined climate change as a “change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer”. This may occur due to natural variability or as a result of human activity. The change may be in the form of magnitude or variability of a single or multiple weather variables or weather phenomena. Global shift in temperature and precipitation pattern as well as increasing frequency of extreme weather events are consequence of climate change which is perceived over several decades. Climate change is indeed increasingly recognized as a considerable risk to agriculture particularly with respect to direct impact on crop production and yield stability (Barzman, 2015).

Effect of Climate Change in Global Warming and Greenhouse Gases

Global warming as the resultant of climate change has become an issue of serious concern worldwide for existence of life on the earth. Over past hundred years, the global temperature has increased by 0.8⁰C and is expected to reach 1.1-5.4⁰C by the end of next century. Major factors affecting the global warming and the climate change is the concentration of greenhouse gases like carbon dioxide, methane and nitrous oxide. On the other hand, CO₂ concentration in the atmosphere has increased drastically from 280 ppm to 370 ppm and is likely to be doubled in 2100 (IPCC, 2007).

10.1 Introduction

The IPCC predicts the global average surface temperature to increase by 1.4 – 5.8 ^oC by 2100 with the increased atmospheric carbon dioxide (CO₂) concentration from 540-970 ppm over the same period. The atmospheric CO₂ concentration and temperature, both, showing a steep rise since last three decades and their impacts experienced across all sectors of agriculture. Serious concerns have been raised about the effects of global environmental change on community and ecosystem functioning. Climate change scenarios generated from General Circulation Models (GCM) with a doubling of atmospheric CO₂ predicted various extreme weather events viz., warming temperatures, increase in anti-cyclonic behaviour during the summer which may result in 20% increase in the precipitation, and long periods of drought between rain bearing storms.

Introduction

According to the Intergovernmental Panel on Climate Change, climate change refers to the long-term changes (typically decades or longer) in the average state of the climate with statistically significant variations.

The climate change, defined as the long-term imbalance of customary weather conditions such as temperature, radiation, wind and rainfall characteristics of a particular region, is likely to be one of the main challenges for mankind during the present century.

A general definition of climate change is a change in the statistical properties (principally the man and spread) of the climate system when considered over long periods.

Climate Resilience

Climate resilience can be generally defined as the capacity for a socioecological system to: Absorb stresses and maintain function in the face of external stresses imposed upon it by climate change. Adapt, reorganize, and evolve into more desirable configurations that improve the sustainability of the system, leaving it better prepared for future climate change impacts.

Prevailing climate and weather conditions play crucial role in production and quality of various fruits including mango (Mangifera indica L.). In India, mango has 2.3 million ha area with annual production of 20.5 million tonnes and average productivity of 8.9 t/ha. However, erratic precipitation and high temperature during flowering and fruit setting induced mainly due to climatic disturbance in the recent past had adversely impacted the production potential of mango in subtropics. Analysis of twenty years (2001-02 to 2021-22) weather data of ICAR CISH, Lucknow, indicated that average annual rainfall of the region is 956.41 mm spread over 25-30 number of rainydays.

INTRODUCTION

Potatois an important crop for food and nutritional security of India. Itis mainly grown as rabi crop and 90 per cent of itscultivation is confined to northern Indo-Gangetic plains comprisingthestatesof UttarPradesh, WestBengal,Bihar, Punjab and Haryana. Due to climate change, the main potato season is likely to be warmer than the rest of the seasonsof the year and will affect seriously the potato production in India. Climate change is defined by Intergovernmental Panel on Climate Change (IPCC) as a plausible future climate thathas been constructedfor explicitusein investigatingthepotential consequences of climate change. It is the difference in climate over a period of time (with respect toa base line or a reference period) and corresponds to a statistically significant trend of meanclimate or itsvariability persistent over along period of time. Climate change may be due to both natural aswell asanthropogenic factors. Reference periods are typically of three decadesused as climatological baseline period in impacts and adaptation assessments to Global climate model. The future climate minus baseline climate are used for model scenario comparison of most climate variables. Typically a number of fixed time horizons in the future are produced from model output.For example 2020 (2010-2039), 2050 (2040-2069), 2080 (2070-2099). Future climates are estimated through models, called global circulation models, or global climate models (GCM). GCM simulations are carried out by means of a large set of heavy computations. The IPCC TAR reported 7 GCMs for developing climate scenarios while IPCC FAR reported 21 different GCMs.

Introduction

Birds lack sweat glands; hence non-evaporative cooling mechanism (radiation, conduction and convection) is the major route of heat dissipation within thermoneutral range. Beyond this TNZ, majority of heat loss occurs as insensible heat loss i.e., Panting. Panting is one of the visible responses in poultry during exposure to heat stress associated with considerable energy expenditure. This specialized form of respiration dissipates heat by evaporative cooling at the surface of the mouth and respiratory passage. Panting increase, the loss of CO2 from the lungs, this leads to a reduction in the partial pressure of CO2 and also reduces bicarbonate levels in blood plasma. In turn, the lowered concentration of hydrogen ions leads to rise in plasma pH, a condition generally referred to alkalosis (Daghir, 2009). Birds also respond by reducing their feed intake and thus metabolizable energy (ME) intake to reduce thermo genesis as an adoptive mechanism. If panting fails to prevent their body temperatures from rising, the birds become listless, comatose and soon die due to respiratory, circulatory or electrolyte imbalances (Saif et al., 2003).

Introduction

In the recent years, climate change emerged as the single most pressing problem globally, and accordingly received an increased attention (Berrang-Ford et al., 2011). It is evident that human activities are responsible for the climate change. Natural processes may also lead to climate variability and change. The climate change forecasts resulted from simulation models indicate that the future climate is likely to turn into more capricious nature with more occurrences of extreme events (IPCC, 2013b). Future projections according to the World Bank (2010) reveal the need of raising food production by 1.8% per annum between 2005 and 2050 due to climate change rather than 1% per annum if there were no impact of climate change. The effect of climate change can be seen on the quantity and quality of various components in the global hydrologic cycle (Milly et al., 2005; Bates et al., 2008).

In South Asia, vulnerabilities to the climate change are the largest in semi-arid and arid countries, where rainfall is concentrated over a few monsoon months, year to year variations are high, and where water resources are decreasing (Lenton, 2004). Cruz et al. (2007) indicated that climate trends and variability can be characterized by increased air temperatures, which are more pronounced during the winters compared to the summers. Across the entire Asia, both spatial and temporal variability in rainfall trends observed during the past few decades may be attributed to climate change. It is likely to happen that climate change will extend the dry season when negligible or very low flows occur, which particularly affects the water management process due to inability to rely on water storage reservoirs or groundwater resources situated at great depths (Giertz et al., 2006).

6.1 Introduction

The change in climatic factors over the years is affecting the entire ecosystem. According to Intergovernmental Panel on Climate Change (2007), the global surface temperature is predicted to increase between 1.4 and 5.8 ^oC by the year 2100. Microbial and plant metabolic processes are often dependent on environmental factors (for e.g. temperature and moisture), enzyme activity, and nutrient availability all of which are likely to be affected by climate change (IPCC, 2007). The global atmospheric concentration of carbon dioxide, an important greenhouse gas (GHG) largely responsible for global warming, has increased from a pre-industrial value of about 280 ppm to 389 ppm at present. Similarly, the global atmospheric concentration of other important GHGs like methane and nitrous oxides has also increased considerably. The increase in GHGs was 70% between 1970 and 2004.

Rising atmospheric CO₂ is able to change the physiological activities of plants and soil micro organisms which in turn control the flow of carbon (C) and nitrogen (N) in terrestrial ecosystems. The change in climatic factors also alters the beneficial plant-microbe interactions, which may be positive, negative, neutral or having variable effects. The survival and activity of microorganisms in the rhizosphere mainly depend on the flow of carbon in the root exudates. The composition of these root exudates is affected by various environmental factors such as soil type, pH, light intensity, oxygen status, soil temperature, soil moisture and nutrient availability. Diverse microbial activities pose a major challenge to predict the response of microbial community to global climate change. These changes in microbial activity have larger impacts on vital ecological processes such as nutrient cycling.

Sericulture, the art and science of silk production through silkworm rearing, is profoundly influenced by weather conditions. Optimal weather is not just beneficial; it’s often a prerequisite for successful mulberry cultivation and healthy silkworm development. Deviations from ideal conditions can lead to decreased productivity, increased disease incidence, and ultimately, economic losses for sericulturists.
20.1. Weather’s Influence on Mulberry Cultivation
Mulberry (Morus spp.) leaves are the sole food source for the most commercially important silkworm, Bombyx mori. Therefore, the health and productivity of mulberry plants are paramount. Weather parameters significantly affecting mulberry growth (Fig. 20.1) include:
Temperature: Mulberry thrives in a mean atmospheric temperature range of 24 to 28oC . While it can survive between 13.0 to 37.7oC, optimal growth and bud sprouting occur within the narrower ideal range. Temperatures outside this can stunt growth and leaf quality.
• Rainfall: An annual rainfall between 600 mm and 2500 mm is suitable for mulberry. In regions with lower rainfall, irrigation becomes essential. Consistent moisture is crucial for leaf yield and quality. Excessive rainfall can lead to waterlogging, harming the plants.

Growing food demand requires increased agricultural productivity, but climate change poses serious challenges to crop protection and food security. Rising temperatures, elevated carbon dioxide, altered precipitation, droughts, floods and extreme weather events directly affect crops and indirectly influence pests, pathogens and their natural enemies. Changes in climatic conditions can alter insect development, survival, reproduction, seasonal activity, geographical distribution and pest status. They may also disrupt host–pest relationships, encourage invasive species and contribute to the decline or displacement of existing species. This chapter examines climate-induced changes in crop-pest scenarios and emphasizes the importance of monitoring, forecasting and adaptive pest-management strategies for protecting agricultural production.

The steadily-increasing human population has led to a rise in the demand for food. As more land comes under agricultural cultivation there will be more pressure on natural ecosystems. Climate change will affect agricultural yield directly because of aberrations in temperature and rainfall, and indirectly through changes in soil quality, pests and diseases. In particular, the yield of cereals is expected to decline in India, Africa, and the Middle East. As the temperature rises conditions will become more favourable for pests such as grasshoppers to complete a number of reproduction cycles and thereby increasing their population. In the higher latitudes (in the northern countries) agriculture will benefit with the rise in temperature as the winter season will be shorter and the growing seasons longer. This will also mean that pests that will move towards the higher latitudes as the temperatures rise. Extreme weather conditions such as high temperature, heavy rainfall, floods, droughts, etc. will also affect crop production.

Abstract

The north eastern region of India, consisting of the eight states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, has an area of 255 090 km2 with a vigorous monsoon dominated climatic and a dynamic hydro-geomorphic regimes. Endowed with a sub-tropical type of monsoonal climate, the region shows remarkable variability of weather and climate on a regional scale. It possesses about 30% of the total water resources potential and about 41 % of the total hydropower potential of India. The per capita and per hectare availability of water in this region is the highest in the country. The problems of environment degradation in the northeastern areas of India are, primarily impacted by demographic pressure, urbanization, natural disasters, soil erosion and land degradation. The region is visited by the southwest monsoons which make it one of the wettest areas in South Asia as well as highly frequented by the water induced disasters. The rapid melting of glaciers is initially expected to first contribute to excessive water flow and flooding in the region. Eventually with the full loss of glaciers, the shortage, when it comes, will likely arrive much more abruptly in time; with water systems going from plenty to want in perhaps a few decades or less.

5.1 Impact of climate change on agriculture

Climate change has both positive and negatively impact on agriculture, food security and land degradation. Climate change could exacerbate the land degradation processes by increases in rainfall intensity, drought frequency and severity, dry spells, f looding, heat stress, sea-level rise and permafrost thaw. The 1/4^th of ice-free land area in the world is prone to human-induced anthropogenic degradation (Certini and Scalenghe, 2011; Hooke et al., 2012). Soil erosion rate is 20-100 times faster than that of soil formation in agricultural field. The erosion rate is least is zero-tillage (non-disturbed field) and maximum at conventional intensive tillage practices. Climate change further exacerbates the land degradation. The permafrost areas, dry-lands, low-lying coastal regions, river deltas are more vulnerable. The occurrence of drought in dry-land was increased by around 1% per year during 1961-2013 periods. On an average 380-620 million people globally experienced desertification who lived in dry-land areas (1980s and 2000s) in South and East Asia, North Africa, Middle East, Sahara region, and Arabian peninsula. Moreover, people who are already living in degraded/ desertified regions are more negatively affected by climate change.

Specifically, the land surface air temperature has increased about twice as much as the global average temperature since the pre-industrial era. The land-surface air temperature has increased relatively higher than the world’s average surface (land and ocean) temperature since the pre-industrial era (1850-1900). The average land-surface air temperature has enhanced by 1.53°C (1.38-1.68°C), whereas, world’s surface (including land and ocean) air temperature has enhanced by 0.87°C (0.75-0.99°C). Subsequently, global warming triggered the frequency, intensity and duration of heat waves and related damage. The direct and indirect impacts of climate change on global agriculture is summarised below for an overall idea about the importance of the issues.

INTRODUCTION

Aquaculture had undergone rapid expansion and intensification in the recent past and has taken the shape of a full-fledged diversified industry. But the risk involved in aquaculture activity has also increased significantly due to the outbreak of diseases which has a devastating effect on the aquaculture crops. Fish are aquatic and poikilothermic, their existence and performance are dominated by the quality of their environment . The aquatic environment is a complex system subject to constant physical and chemical changes brought about by natural and manmade processes. Therefore, choosing the proper site to develop aquaculture facility is paramount to its success.

A disease is an abnormal condition of an organism caused by infection, inherent weakness or environmental stress; it prevents the organism from functioning normally which ultimately leads to death (Avault, 1998). In an aquatic environment, there is a profound balancing of relationship between host (fish), pathogen and the environment existing and this is the fundamental concept to disease susceptibility of fish (Snieszko, 1973). A disease organism may be present in the environment or host, but will not cause disease as long as the host has high natural resistant or the physical condition of the host is strong. Once the imbalance is created to any of the component, opportunistic pathogen invades the host resulting to the outbreak of disease.

Foot and mouth disease (FMD) is the most contagious disease of animals and has a great potential for causing severe economic losses in susceptible cloven-hoofed animals. FMD has been classified as a Transboundary Animal Disease (TAD) which is highly contagious or transmissible and has the potential for very rapid spread, irrespective of national borders, and causing serious socio-economic consequences. FMD has constituted a recognised threat to the health of livestock for over 500 years and still remains a serious hazard to the productivity of animal populations throughout the world. The large numbers of virus serotypes and subtypes, the ease of transmission and the limited efficacy of vaccination make control complicated and difficult. Contribution of environmental variables for emergence and distribution of infectious diseases has long been recognized by many researchers. India is largely subject to four seasons: winter (January and February), summer (March to May), a monsoon (rainy) season (June to September), and a post-monsoon period (October to December). There are reports on effect of environmental parameters such as relative humidity, windspeed and air temperature on the spread of the disease. FMD is endemic and at a high prevalence in many countries in Africa, the Middle East and Asia and is also present in parts of South America. Europe, North and Central America, the Pacific nations and the Caribbean are free from the disease. FMD in India is the biggest impediment to growth of livestock sector. FMD outbreaks occur in India throughout the year. The outbreaks occurred round the year with maximum occurrence during October to March, and in May and June (Fig. 15.1). Foot and mouth disease is associated with an aphthovirus (family picornaviridae) which occurs as seven major serotypes: A,O,C,SAT1, SAT2, SAT3 and Asia1. FMD is characterized by fever, profuse salivation, vesicles in the mouth and on the feet and a drastic reduction in milk production; sudden death in young stock may occur (Radostits et al., 2006).

In the existing planetary system, life was established and growing over millions of years on earth. If we track down to the history of evolution, beginning with a living unicellular organisms Amoeba, growing to a gigantic size of Dinosaur and stabilizing at well adaptable stage of an Elephant in animal kingdom or to reach the present status of the intelligent human being, throughout these developmental stages the climatic/meteorological factors play a crucial and supportive role. Further the Development of plant/Animal kingdom is making rapid strides in tropical climatic zones where the temperature ambient ranges between 20⁰C to 40⁰C and the rain fall/humidity factors are moderate. We are fortunate enough that India is geographically located in tropical zone. This classic location advantage of the country in the world geographical map helped the country in keeping India as number one milk producer in the world, no 3 producer in poultry egg production, number 5 in horticulture production i.e fruits and vegetables. Climate change affects livestock both directly and indirectly. Direct effects from temperature, humidity, rainfall, wind speed and other climate factors, aggravates the heat stress in dairy animals, and influences animal performance badly: in growth factors, milk production in Dairy animals, mutton production/ wool production in case of sheep. egg and meat production in poultry, and reproductive aspects in all the species. The indirect impact of these factors on livestock may result on economic, nutritional and health aspects of human society and also its contribution to the economy of the country.

Introduction

Poultry production is one of the fastest growing sectors of livestock industry in developing countries. Environmental variation is one of the major factors that affect sustainability of poultry production systems in tropical climate (Sinha et al., 2017a). Adverse climatic stress declines the production performance of chicken which causes high economic loss to the enterprises as well as the farmers. Heat stress has an adverse effect on egg production, egg weight and shell quality of laying hen (Whitehead et al., 1998). Climatic variables like temperature, humidity, radiation and wind speed that directly affect the mechanism of thermoregulation and rates of heat exchange by all animals (NRC, 2001). Heat stress is a major factor that decreases productivity and reproductive efficiency of livestock due to lower feed intake and negative energy balance (De Rensis and Scaramuzzi, 2003). Moreover, it badly affect the production due to decline feed digestibility such as proteins, fats, starch (Bonnet et al., 1997). In addition, the acute heat stress drastically decreases the reproductive performance of hens due to alterations in acid-base balance and ion exchange mechanism (Mahmoud et al., 1996). Climate change in?uences the emergence of disease and their transmission due to increases vectors, pathogens. All the above effects impact a huge economic loss to the farmers as well as the country.

Introduction

Our soil resource is generally taken for granted for many uses. Most people don’t realize the importance of the resource and that it is fundamental for farming/agriculture. Without high quality soils, agriculture production cannot be achieved on a sustainable basis to meet ever growing demand. Thus, conservation agricultural practices are capable of improving soil health by increasing organic carbon, aggregation, improving infiltration and minimizing erosion losses.

Introduction

The main aim of conservation agriculture is to sustain and improve the crop productivity and to provide protection against biotic and abiotic stress, while at the same time protecting and enhancing the biological activities of the soil. The essential principles of conservation agriculture are no-tillage (and direct seeding) or reduced tillage, the maintenance of a cover of live or dead vegetative mulch on the soil surface and the wise use of crop rotations. The crop sequences are planned in such a way that which will discourage the buildup of pests or diseases and will help to optimize plant nutrient use by synergy between different crops of the rotation. While deciding the crop rotation, the locally important crops should be considered and there should be deep rooted and shallow rooted crops in the sequence so that the utilization of soil nutrients is maximized. At least one leguminous crop should be there in the crop sequence. The use of plant residues influences the soil physical, chemical and biological properties by reducing surface temperature, rate of evaporation and maintaining water content, nutrient load and rate of organic matter decay. The soils under conservation agriculture are happened to be highly active and diverse biologically and can supply plant nutrients for a longer period of time because of their higher nutrient loading capacities.

Soil biodiversity comprises of all organisms whether single-cell organisms or multi-cell animals or plants that live in the soil. Soil microbial diversity includes “genetic diversity, that is the amount and distribution of genetic information within microbial species, diversity of bacterial and fungal species in microbial communities, and ecological diversity, that is variation in community structure, complexity of interactions, number of trophic levels and number of guilds (Nannipieri et al., 2003).

Livestock is considered one of the essential variables in the revenue of a farmer. The sector (excluding fisheries) contributes 30 per cent to India’s agriculture gross domestic product, and it is valued at more than Rs. 9 lakh crores. India is also one of the largest producers of milk in the world; around 70 million rural households are engaged in professions linked to dairy. India is also the second largest exporter of bovine meat after Brazil. This sector provides a substantial income to farmers and supports the economy by generating enough demand in the rural and semi-urban regions. This animal husbandry sector comprising dairy and poultry is extremely valuable for farmer’s income security, and Covid-19 has the potential to disrupt this sector.

In developing countries such as India, where dairy farming is one of the most important sources of livelihood for 60 million rural households, 80 per cent of whom are landless, small and marginal farmers who depend on dairy for daily income, the crisis is extreme. Thus, even a small decline in the growth of the dairy sector significantly affects a large chunk of our population which are already vulnerable due to low income, poor savings, and lack of livelihood alternatives. Small production in multiple households leads to more reliance on efficient transportation for procurement. In addition to this, the Indian dairy sector is still dominated by the unorganized sector which handles more than 50 per cent of the marketable surplus. Milkman and vendors collect a small quantity of loose milk from different households and then supply it to urban consumers, roadside eateries, hotels, and sweetshops. Closure of shops and restrictions on transportation has ruthlessly disturbed this arrangement. Even in the formal sector out of the total milk processed 65 to 70 per cent is sold as liquid milk which is immediately vended after packing and only 30 per cent is processed into other dairy products like ghee, butter, cheese, curd, ice-cream, milk powder, etc. Thus, the formal sector also lacks sufficient infrastructure and storage facilities for processing and storing surplus milk after value addition.

Introduction

The COVID-19, the Global Pandemic has affected the world and is still continuing with its various mutations even today. This has created a long-lasting impact and many sectors like energy, transport, industries, and residential buildings, have critically experienced impacts from the pandemic (Qarnain, Muthuvel, and Bathrinath 2020). It has directly and indirectly impacted every household’s operations. The mandatory COVID – 19 protocols, lockdowns, Work From Home (WFH) schedules and the major fear of every one of contracting the disease if going out itself has forced people to stay indoors and forced residents to use more energy for their daily routine activities, (routines like watching more TV, using environment control devices like fans, AC, room heaters etc.) giving rise to higher energy usage resulting in high energy bills and subsequent scarcity in the energy supply.

The COVID-19 pandemic has significantly impacted agribusiness communications, creating unprecedented challenges and opportunities for the sector. With restrictions on transportation, shortage of labor, and changes in consumer behavior, agribusinesses have had to adapt their communication strategies to remain operational and retain consumer trust. The objective of this chapter is to analyze the impact of the COVID-19 pandemic on agribusiness communication and suggest effective communication strategies to overcome the challenges posed by this and similar crisis which might arise in the future.

Agriculture and allied sectors have adversely hit by the COVID-19 scare.The rumors of poultry birds likely the carrier of the virus circulated in social media had led to reduced demand of the chicken meat in several parts of the country in the month of February 2020 even before India reported the first case of COVID-19. The poultry industry in India hit hard because of nationwide lockdown to stop the rapid spread of COVID-19 virus. This lock-down had disrupted the entire supply chain. Before COVID-19 the prices for broiler was about Rs. 80 per kg and Rs. 4 for egg the price dropped to almost no value like Rs. 6 per kg and Rs. 1-1.50 per egg. As a result, the projected loss of the industry was about Rs 25000 crore. (Shukla & Bhattacharyya, 2020).
According to industry sources, the poultry industry which had witnessed steady growth rate in the last two decades because of rising consumer demand for protein rich food especially but, it has incurred huge losses since the beginning of the 2020. The loss incurred by Indian poultry industry is mainly attributed to sharp decline in demand because of disruption of supply chain during lock down. The financial condition of all the stakeholders in the poultry value chain – farmers, feed suppliers and retailers had become risky. The drop in demand and supply chain disruption especially hit the smaller farmers who had limited
resources. Thus, many farmers went for ‘contract farming’ offered by many large poultry players.

Introduction

With the advent of modern agricultural technology, especially during the period of the Green Revolution in the late sixties and early seventies, there was a continuous surge for diversified agriculture, primarily on economic considerations. The changes in cropping pattern, however, are the outcome of interactive effect of many factors which can be broadly categorized into the following five groups-

Resource related factors like irrigation, rainfall and soil fertility.

Technology related factors viz. seed, fertilizer, and water technologies on one hand and marketing, storage and processing on the other.

Household related factors like food and fodder requirement as well as investment capacity of the farmers.

Price related factors covering input and output prices and economic policies that affect these prices.

Institutional and infrastructure related factors pertaining to farm size and tenancy arrangements, research, extension and marketing systems and government regulatory policies.

Introduction

The process of making the rumen of animals free of rumen protozoa is called defaunation and the animal is called defaunated animal. The role of rumen ciliate protozoa on the performance of host animals became debatable issue when Becker and Everett (1930) demonstrated that rumen protozoa were non-essential for growth in lambs. Nevertheless, the reports of recent years reflect that though protozoa may be non essential for ruminant, still they have significant role to play in the rumen metabolism specially to stabilize the rumen pH (Santra and Karim, 2002a). Rumen protozoa are the largest in size among rumen microbes and contribute 40-50% of the total microbial biomass and enzyme activities in the rumen (Agarwal et al., 1991).

Introduction

India’s change in the economic environment and market-oriented economic reforms can be traced back to the 1990s which led to the growth of the country. There was a clear evident change from the condition it was in the 1970s when it was far behind the other Asian countries. The economic reforms brought by LPG (Liberalisation, Privatisation and Globalisation) model have affected not only international trade but also led to an increase in the competitiveness of the industries. But what triggered these economic reforms? Before 1990, India was in a severe economic crisis condition due to repeated policy failures. India was experiencing a huge fiscal and balance of payment deficit, a high inflation rate and a fall in foreign exchange reserves. This led to the sickening of the public sector units whose prime role was to bring a reduction in inequality and poverty. The self-reliance condition in India was not of much help as there was insignificant trade with the rest of the world. The crisis mainly depicted the mismanagement of the resources. In light of this, this chapter discusses the impact of the economic reforms on agri-enterprises.

4.1 Introduction

Circumstantial evidences almost confirm researchers’ on early predictions of a changing climate and a warming world. The trend of changes also establishes the primary influence of increased greenhouse gas concentration on the global warming and the consequential events. The global mean surface air temperature has increased by about 0.74°C over the last 100 years. It is projected to rise 1.4 to 6.4 °C by the year 2100 (IPCC AR4, 2007). Changes will vary from region to region. Eleven of the twelve years in the period 1995-2006 rank among the top 12 warmest years in the instrumental record (since 1880). The radiative forcing of CO₂, CH₄ and N₂O is very likely (> 90% probability) increasing at a faster rate during the current era than any other time in the last 10,000 years. This is because of the increase in the global abundance of the three key greenhouse gases. The atmospheric CO₂ concentration has reached the level of 389 ppm in 2010 (WMO, 2011) from 270 ppm the pre-industrial era. In addition, global abundance of other greenhouse gases such as methane (CH₄) has increased from 700 ppb in the pre-industrial era to 1808 ppb in 2010 and in the same period, nitrous oxide (N₂O) has increased from 270 ppb to 323 ppb.

ABSTRACT

This paper is an attempt to analyze the plausible impacts on the economy and social issues of developing countries with reference to enforcement of IPR.

Introduction

From commodity based nature, business has changed during the past hundred years in a way that ideas and knowledge have taken higher value than commodities. Today, many companies find their most valuable assets being intangible and they are therefore dependent on functioning IPR systems. But does the rigid protection of IPR serve all the people in our globalized world? The purpose of this paper is to discuss the impact of the introduction of IPR protection on developing and under developed countries in the light of TRIPS Agreement.

Introduction

The advancements in the field of informatics, biology and allied fields of technology led to the emergence of an inter-disciplinary field known as ‘Bioinformatics’ (Kumar 2006, Madhan Mohan 2006). Explosion of knowledge in the field of biology and generation of new information (data) needs collection, storage, organization, integration, analysis, simulation of biological data and a faster distribution among the scientific workers (Mehrotra et al. 2005). The advent of super computers, high speed computing and development of algorithms for data formatting, assists in the storage of data at the site of origin and distributed through the hyperlinks in world wide web (www).

The vast field of Bioinformatics is beyond the scope of this article. However to elucidate the concepts that led to the the development of Bioinformatics vis-à-vis is given in brief before explaining the new and emerging area of ‘fluxomics’.

2.1 Introduction

Each step in the food industry system e.g. food production, processing, transportation, storage, distribution and marketing, has some impact on the environment and there is much concern about environmental pollution. Due to the highly diversified nature of the food industry, various food processing, handling and packaging operations create wastes of different quality and quantity, which, if not treated, could lead to increasing disposal problems and severe pollution problems [24]. The preservation of the natural environment from industrial pollution is currently receiving much attention. In food industry, the most important problem is treatment and disposal of large quantities of waste water, a by-product of various processing operations. It is one of the largest industry groups comprising the manufacturing sector of the U.S. economy [47]. Likewise, India is the world’s second largest producer of food next to China, and has the potential of being the largest food processor. The total food production in India is likely to double in the next ten years [22]. Flour and grain; soft drinks and carbonated water; breweries; starch and miscellaneous food products; meat, poultry and fish; tea, coffee and other beverages; fruit juices; animal feed; sugar; distilleries and blending of spirits; cocoa, chocolates and sugar confectioneries; agricultural and food chemicals and industrial packaging are important sub-sectors of the food processing industry. Food processing projects involve the processing and packaging of meat products, fish and shell fish, dairy products, fruit and vegetables, grains and beverages production. It includes refinement, preservation, improvement of product, storage, handling, packaging and canning (Fig. 1). The processing may involve receiving and storing raw or partially processed plant, animal or other food materials, processing the raw materials into finished products, packaging and storing the finished products.

Food provides a sense of wellbeing and comfort and makes people feel good. In this world of a growing population, the need for affordable, safe and good quality food is rising constantly. On the other hand, there is growing awareness of customers who demand that food be produced and supplied hygienically in socially responsible and eco-friendly ways.

Introduction

Pulses are the most important part of our diet, richest and cheap source of proteins, vitamins, minerals and amino acids besides high nutritional value. Hence, the economic value of these crops is very high. Pulses can be produced with a minimum use of resources and are mostly cultivated under rainfed conditions and do not require intensive irrigation (Sood et al. 2018). Keeping in view large benefits of pulses for human health; the United Nations has proclaimed 2016 as the International Year of Pulses. Thus, due attention is required to enhance the production of pulses not only to meet the dietary requirement of proteins but also to raise the awareness about pulses for achieving nutritional, food security and environmental sustainability. The Government of India through Indian Council of Agricultural Research (ICAR) has established a wide network of Krishi Vigyan Kendras (KVKs) in all the rural districts of the country. These KVKs under the aegis of the National Agricultural Research and Education System are the real carriers of frontline technologies and impart knowledge and critical input support for the famers. The frontline demonstration programme (FLDs) in pulses is a unique programme by Ministry of Agriculture, Govt. of India, conducted under close supervision of farm scientists. Main objective of FLDs in pulses is to demonstrate and popularize the improved agro-technology on farmers fields under varied farming situations for effective transfer of generated technology and f ill the gap between improved technology and adopted/indigenous technology to enhance pulse productivity and farms gains for sustaining the production systems especially under rainfed farming (Choudhary et al. 2009). The field demonstrations conducted under the close supervision of scientists of the National Agriculture Research System is called front-line demonstrations. The main objective of Frontline Demonstrations is to demonstrate newly released crop production and protection technologies and its management practices in the farmers’ field under different agro-climatic regions and farming situations.

Acinetobacter baumannii is an opportunistic pathogen giving rise to nosocomial infections causing threat to public health. Studies of biofilm-forming genes was done in A. baumannii isolates by PCR technique. To study the relationships of genes a technique based on PCR sequences along with multilocus sequence typing (MLST) were utilized (Saeed et al., 2020). Goudarzi, Mehdi et al. (2019) studied the genetic diversity and biofilm formation analysis of Staphylococcus aureus causing urinary tract infections in Tehran, Iran. The biofilm forming and adhesion encoding genes were studied along with distribution of different agr and spa types in S. aureus isolates by PCR screening and multiplex PCR. The workers found that the ability to produce biofilm was higher among MRSA strains as compared to MSSA strains. The most prevalent biofilm forming gene was icaD (77.3%), followed by icaA (76%), icaB (57.3%) and icaC (50.7%). Acinetobacter baumannii is a nosocomial pathogen which is commonly present in hospitals and is a causal organism of many diseases. A. baumannii isolates have been known as multidrug-resistant (MDR). For controlling such serious organism only molecular techniques have been found to be effective.
