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.

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.

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.

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.

Introduction

The state of Maharashtra now again reels under the scarcity of water. Geologically, major part of the state is covered by Deccan basaltic flows. This basaltic terrain, as such, has been labelled notorious as far as the availability of groundwater is concerned. Uncertain availability of groundwater in the terrain is due to heterogeneity in the nature of piles of basaltic flows which adversely affects the geohydrological characters of the rocks.

The area understudy is unfortunately, a part of basaltic terrain in which no storage structures like major dams or medium projects have been constructed across the existing rivers. Consequently, the irrigation in the area and domestic needs of the people solely depend on whatever water is available in the existing dug wells. The wells do not suffice the need of the people because the percolation of water in the wells is not adequate in major part.

INTRODUCTION

Inspite of recent technological developments which have helped to increase agricultural production in many countries, growth of plants and animals continue to depend to a large extent on the weather conditions. Each plant has its own climatic requirements for growth and development and any large scale deviation from it exert negative influence.

Growth of plants is most sensitive to temperature just above a threshold value and near the maximum value, where growth normally stops. Therefore, periods of extreme temperature i. e. low temperatures below the threshold value and high temperatures above the maxima are hazardous to plant development and growth. Extreme temperature conditions during cold spells cause stress and frost; high temperatures lead to heat stress, and both affect agricultural production. Snow and ice storms in late spring or early autumn are very hazardous to many temperate crops.

Similarly extremes of moisture conditions namely dry desiccating winds, drought episodes and low moisture conditions as well as very humid atmospheric conditions including wet spells tend to affect agriculture. High soil moisture situations of water logging and flooding associated with heavy rainfall and tropical storms have adverse effect on plant growth and development since they influence the rate of transpiration, leaf area expansion and ultimately plant productivity. Drastic changes in rainfall variability can have very significant impact, particularly in climatically marginal zones such as arid, semi-arid and sub-humid areas where incidence of widespread drought is frequent. Dry desiccating and strong winds reduce agricultural production as a result of very high evapotranspiration rates. It also causes mechanical damage to plant with weak stems by lodging such as the sugarcane and the banana.

Introduction

Environmental Assessment is taken up in this exercise as a rapid assessment technique for determining the current status of the environment and identifying impact of critical activities on environmental parameters. EIA is a relatively new planning and decision-making tool first enshrined in the United States in the National Environmental Policy Act of 1969. It is a formal study process used to predict the environmental consequences of any development project. EIA thus ensures that the potential problems are foreseen and addressed at an early stage in project planning and design. Creation of Environmental Impact Assessment (EIA) system is vital to conform socio-economic development projects to environmental safety and thereby ensure sustainable economic development. In view of the fact that development is an ever-growing process, its impact on the environment is also ever increasing, leading to rapid deterioration in environmental conditions. As such Environmental Assessment provides a rational approach to sustainable development.

It also enables us in carrying out Environmental Cost-Benefit Analysis of projects at an initial stage. It is thus a precursor to detailed analysis of environmental impacts, which are taken up only if a need for the same is established.

3.1 Introduction

Ozone (O₃) is present throughout the atmosphere and can have either positive or negative effect depending on where it is found. The stratosphere (15-50 km) has the largest (90%) concentrations of O₃ (Colls, 1997). Stratospheric O₃ is important as it regulates the transmittance of ultraviolet light to the surface of the earth. Hence reductions in stratospheric O₃ in Polar regions, particularly the Antarctic “ozone hole”, are of concern regarding the health effects of exposure to increased levels of ultra violet (UV) radiation. In the troposphere (0-15 km), O₃ is a toxic pollutant of global importance and it is a major constituent of photochemical smog. Interest in pollutant O₃ and in its effects on living organisms has increased in the last decades as a consequence of the rise in its ground-level concentration and of the widening of its diffusion (Ashmore, 2005). Economic growth requires more energy production, which would result in increased production of NOx and volatile organic compounds (VOCs) precursors for O₃ formation (Ghude et al., 2008).

In this chapter we will cover all the basics libraries and some frameworks of machine learning, deep learning and computer vision. We will discuss all about their use with an example and instruction which will states the commands to install to those libraries for building any project in our system. So let’s begin

What is a Library?

Library is an aggregate of features and methods that allow you to take many actions without getting your own code written.

For instance, the libraries that you have to know are if you work with data, numpy, scipy, pandas, etc. They have very simple data processing functions that save you time for small tricks.

The primitive people were living as part of the environment along with other f lora and fauna in a perfect synchrony. Prior to industrialisation the people were living in an environment friendly manner without causing much damage to natural resources. During the time they were making good progress and were building huge structures which are of technical excellence even today. Post industrialisation the whole scenario changed very fast. The population increased many fold, people started making more goods than required to have a market hold to earn more – the human greed increased beyond limit.

Increased importance of research publications, impact factor and citations as metrics in evaluating science and assessing the quality of research is driving unethical practices too in research and publications. Adding to that, limited access to research publications, exuberant subscription charges, heavy article processing charges and several other transboundary science and technology issues are further dividing the scientific community which is severely impacting the progress of the Nation (Pathak, 2025). The National Academy of Agricultural Sciences (NAAS) journal rating system serves as a cornerstone for researchers in India, particularly in the domain of agricultural sciences. Its significance lies in providing an accessible and systematic framework for evaluating the quality and relevance of academic journals. This chapter explores avenues for enhancing the NAAS journal rating methodologies to ensure greater accuracy, inclusivity, and ethical rigor in the assessment process. By integrating global best practices, incorporating diverse metrics, and addressing emerging challenges in the academic publishing landscape, the proposed framework aims to make NAAS ratings more robust and globally competitive. To enable universal access to scholarly scientific literature, under Aatmanirbhar Bharat it would be appropriate to strengthen our own Indian Journals to compete globally in the long run. In this regard, NAAS rating of Agri-journals has been a progressive step and NAAS should continue to upgrade its evaluation mechanism. The Professional Association of Agricultural Societies (PAAS) and NAAS partnership in upgrading of publications in Indian society journals should be encouraged.

3.1 Introduction
Understanding the Earth’s atmosphere—its intricate dynamics, ever-changing weather patterns, and long-term climate trends—hinges critically on the quality and detail of the observations we collect. While remote sensing technologies offer broad perspectives from a distance, a fundamental and indispensable category of atmospheric data comes from in situ observations. The term “in situ,” meaning “in place” or “on-site,” precisely describes the nature of these measurements: they are direct, physical readings taken within the atmospheric volume itself.
These direct observations are the bedrock of meteorological science. They provide the ground truth for atmospheric conditions, offering unparalleled precision in measuring parameters such as temperature, humidity, atmospheric pressure, wind speed and direction, and the characteristics of precipitation. Unlike indirect sensing, in situ methods involve instruments physically interacting with the air, yielding highly accurate and localized data points. This granular detail is crucial for a multitude of applications: it allows for the precise calibration of remote sensing instruments, provides essential validation for complex numerical weather prediction models, and enables scientists to dissect and understand fine-scale atmospheric processes that influence local weather.

INTRODUCTION

Prediction of helminthic infections is impractical. The aim of any control programme must therefore, ensure that parasite populations do not exceed levels compatible with economic production. The parasitological monitoring (e. g. faecal egg counts or pasture sampling) at intervals, forecasting on the basis of meteorological data and computer simulation may provide an alternate approach to control parasitic infection (Brunsdon, R. V. , 1980) in a given geographical area. The most common gastrointestinal parasite prevalent throughout the year in Meghalaya, India is Strongyle infection. This is because of the high rainfall and humidity prevalent in the North-Eastern region.

As the prevalence of this infection is mainly dependent on rainfall and humidity, study was being initiated to identify the relationship between rainfall/temperature and strongyle infection. The study would be also helpful in predicting/ forecasting the disease occurrence based on the prevailing pattern of rainfall in a particular location.

In an era defined by rapid technological advancements and an ever-changing climate, the need for precise, adaptive, and actionable weather intelligence has never been greater. As global weather patterns become more erratic and extreme events increasingly disrupt lives and livelihoods, the integration of real-time field response into weather intelligence systems represents a transformative opportunity. Just as companies like Google and Tesla leverage real-time user inputs to continuously update their software, refine artificial intelligence (AI) models, and provide timely road-and-traffic guidance, weather intelligence systems that are continuously refined by feedback from farmers, fishermen, and other local stakeholders offer the promise of dynamic, “live” insights that can revolutionize agricultural practices and community resilience (Fig.10.1). This chapter delves into the critical importance of collecting and synthesizing feedback from those who are on the frontlines of weather impacts. It explores the methodologies and benefits of integrating real-time field data into weather intelligence systems, drawing parallels to the iterative processes observed in hightech industries. In doing so, we highlight how these innovations can maximize

Introduction

It has been observed that the surface waters are getting polluted due to improper disposal of domestic and industrial wastewaters. Most of the River basins which are major supply of water for human activities are polluted. Even the groundwater in not spared because of the incessant growth of the population in India. In Maharashtra the number of bore wells has been increased to 5 Lakhs from 1 Lakhs from few decades only. Out of total area of Maharashtra, 82% is covered by the basaltic rocks made up of lava. That’s why the quantity of the groundwater is comparatively less than the Indo-gangetic plane.

Groundwater in the north region of the Tapi River is found to be hard, unfit for the human consumption. The residences of district like Buldhana, Jalgaon and Dhule have to use hard water for consumption. Rampant extraction of the groundwater for agriculture might have caused alternation in chemical qualities of the groundwater. It has been also well documented that in Marathwada region, groundwater content higher concentration of fluoride and total Hardness.

Fluorine the most electro-negative element is of great interest and importance to human health because of its curative and harmful effects. Fluorides are released by various natural sources and anthropogenic activities into the aquatic environment (that is surface as well as groundwater). Fluoride can enter the human body through drinking water, food, toothpaste, mouth rinses and other dental products, drugs and fluoride containing salts and hydrofluoric acid. It may cause Fluorosis – a crippling and painful disease such as dental fluorosis, skeletal fluorosis and non-skeletal fluorosis.

Abstract

India’s climate policy and its stand in the United Nations Framework Convention on Climate Change (UNFCCC) have developed through a complex and contradictory interactions between global pressures to take actions in the field of climate change, India’s foreign policy orientation, its environmental practices and various other national factors. India has been under growing pressure from the major developed economies and also from many small developing countries to play a leading role in mitigating climate change in keeping with its economic and political importance. National factors, including the very important consideration of maintaining rapid GDP growth, favours a conservative approach, with emphasis on expanding India’s share of global climate space. India ranks high on global climate change vulnerability because of its 7,500 Kilometre-long coastline, high dependence of its agriculture on monsoon, decreasing availability of freshwater and over-exploitation of ground water resources, presence of large population in cyclone-prone areas, low lying river deltas and fragile ecosystems like partially submerged lands, and not least, because of melting of the Himalayan glaciers, which feed close to 70 percent of India’s river waters. In 2008, India formulated a National Action Plan on Climate Change (NAPCC) under international obligations. India’s climate policy has always been the preserve of a small group of individuals protected from societal influence and unaccountable to the public at large. Indian policy makers claim to speak on behalf of those very people who have been consciously excluded from democratic and participatory decision-making. The industrialised economies reluctant to own up to their climate obligation only breeds more cynicism within the Indian society. Whatever the outcome of international conventions on climate change or any kind of global negotiations in the immediate future, India cannot afford to give up on the serious issue of climate change.

As a developing country, India does not have any emission reduction target, but it is able to sell CERs pursuant to the CDM, to large emitters covered by the EU ETS, countries that have emission reduction targets under the Kyoto Protocol, or any other entity that wishes to purchase such CERs for compliance purposes. It can also supply ERs and VERs for the growing voluntary markets.

4.1 Status and Trends

India’s participation in the carbon markets has contributed to the recognition that it is a useful tool in attracting climate friendly investments. India was an early player in the market, and it used the hosting of the Eighth Conference of Parties to the UNFCCC in Delhi in October 2002 to sensitize the business community about the opportunity provided by carbon finance and the modalities of the emerging CDM. In 2004, the growth in the Indian carbon market was fostered by a healthy number of indigenous management and technical consultants, which began to offer services to potential sellers of emission reductions, and the response from primarily the private sector to capacity building initiatives concerning the nascent market. In its capacity as the Designated National Authority (DNA) for the CDM, the Ministry of Environment and Forests (MOEF) also had the foresight to develop simple and transparent rules, whereby project developers can obtain a Letter of Approval (LOA) theoretically within sixty days, which is a key step required for project registration. By the end of 2004, India was the market leader in the forward sale of emission reductions, with 50 % of the supply market. Early successes included the registration of two projects which consisted of the thermal oxidation of HFC-23 generated as a buy-product during the manufacturing of the refrigerant HCFC-22, but also a number of small scale co-generation projects using bagasse, rice husk and mustard crop residues as a source of biomass, and small scale hydropower projects.
