Introduction 

Conservation tillage has been defined based on percent cover of the soil surface with crop residue (CTIC, 2000). Quantifying crop residue cover on the soil surface is important for improving estimates of surface energy balance, net primary productivity, nutrient cycling, and carbon sequestration. Quantifying crop residue cover is also an important factor in controlling soil erosion and evaluating the effectiveness of conservation tillage practices (Barnes et al., 2003). Collecting this information by conventional method of survey and line transact are time-consuming, labor intensive, costly and can involve destructive sampling (Morrison et al., 1993). Moreover, field data are limited because they provide point, rather than area information. Remote sensing technique revealed as promising tool in providing such spatial data over a large area in a time and cost-effective manner.

Improving the skill set of individuals is an important agenda of any development organization. The individuals may be anyone in the system who is directly or indirectly connected to the system.  Agriculture System is a complex and multi-stakeholder system with farmers as the axis of the wheel with other stakeholders’ forms part of spokes of the wheel. The scope for capacity building or training of every stakeholder has been peaking tremendously given the ever changing nature of the profession. The public and private training Institutions are vying with each other for conducting trainings in order to sustain the existence of the Institutions. Though a few institutions are really trying hard to take the technologies in real terms to the farming community, the following observations are very difficult to be masked.

Introduction
As one of the biggest youth demographics worldwide, especially in India Gen Z, represents a distinct consumer segment defined by their digital fluency and progressive values. Their deep integration with technology has reshaped traditional shopping habits, making e-commerce platforms central to their purchasing decisions (Smith, 2020). This generation highly values health and sustainability, pushing e-commerce platforms to address these priorities. This shift is crucial in meeting the evolving behaviours of Gen Z, who emphasize wellness and environmental considerations in their purchasing choices. E-commerce platforms possess powerful tools that influence consumer behaviour, especially with the Gen Z demographic. This generation is well known for its tech-savviness and strong social and environmental consciousness and responds uniquely to online marketing strategies. E-commerce platforms are pivotal in shaping Gen Z’s health and sustainability practices. They achieve this by providing a wide variety of wellness-oriented products and information, which assists in educating and motivating consumers about healthy lifestyle. Additionally, these platforms feature eco-friendly products and promote sustainable practices, aligning the Gen Z’s growing concern for environmental issues. The choice of this topic was inspired by a few things such as health consciousness and sustainable consumption. This interdisciplinary topic combines insights from consumer psychology, digital marketing, and environmental science, offering valuable implications for businesses and policymakers aiming to engage this tech-savvy generation effectively. The focus on this emerging area of research helps fill gaps in existing literature and provides strategic guidance for optimizing digital commerce strategies. Case studies on MyFitnessPal and Nike’s Move to Zero initiative demonstrate how an e-commerce platform can promote health awareness and sustainable consumption among Gen Z. This topic will aid businesses and marketers in customizing their online strategies to align with Gen Z’s emphasis on health and sustainability. It assists policymakers and environmental organizations in formulating improved practices and regulations for responsible consumption. Developers of e-commerce platforms can leverage these insights to design features that align with users’ values. For researchers, it enriches the understanding of consumer behaviour and digital marketing. Finally, it helps consumers to make more informed decisions by demonstrating how e-commerce influences their health and environmental choices.

Despite widespread occurrence and its potency to inflict heavy causalities and damage to economy, generalizations could not be made to define “drought” – leave alone characterization, development of predictive model and common mitigation measures. Regional variation, be it definition or symptoms or causative factors or consequences and mitigation measures is the hallmark of drought. This chapter is an attempt to present a review on characteristics of drought for the benefit of devising mitigation and reclamation measures.

INTRODUCTION

“Drought” denotes the meteorological, agricultural, environmental, climatic, social, economic and political consequences of a gap between the water availability and demands for the needs of domestic, irrigational, industrial, commercial and recreational consumption in an area over extended period of time. As these demands vary from region to region and depend on too many parameters such as quantum of rainfall, geological and soil characteristics, land use, population, economic activity, climatic conditions, population and culture, drought conditions of an area may not have characteristics of some other region.

Introduction

Data are the most critical element of a GIS. It is reported that more than two thirds of the time and expenditure to develop a GIS is spent on data collection and organization. Understanding and appreciating the criticality of data is of paramount significance to practice GIS. This chapter is complementary to database concepts chapter discussed in Level II and deals with the fundamentals to start with and the concepts of building an information organization.

Data - A Definition and Certain Points to Ponder

“Data” are defined as a body of facts or figures, which have been gathered systematically for one or more specific purposes.”

Abstract

Human Resource Management (HRM) is an essential function of every organization. Information Technology (IT) application has made such ‘human resource management’ function easy, to a great extent. Now a day, IT has been used widely across the organizations to perform different functions like, Recruitment, training, maintenance and development etc. Human Resource Information System (HRIS) is one of the latest contributions of IT to the area of human resource management, which is going to revolutionise management in 21st Century. Technology has brought changes in the existing working styles of organisations. By the introduction of HRIS, it enhances the efficiency of the organisation by changing the traditional way of working. In Human Resource Information Systems, many organizations use employee data in traditional ways. These can create conflict with the rights and interests of employees, with external stakeholders, and with society at large. The present paper discusses such issues. Other soft issues like, challenges and possible solutions are also discussed.

Agricultural production in India is still vulnerable to vagaries of monsoon rainfall in spite of rapid technological advancements like 1) Availability of high yielding varieties 2) Improved crop management practices and increased irrigation availability and effective control of pests and diseases and etc, over last few decades. Majority of Indian farming community which broadly comprising of small and medium farmers are often subject to climate extremes such as droughts, floods, heavy rainfall events, heat and cold waves, frost, hail storms during the crop growing season. The probabilities of occurrence of such climate extremes and associated crop damages and production losses are common in tropical countries like India. Compensation to the resource crunched farmers in the form of crop insurance seems to be the best option for speedy recovery from the losses incurred during the season. It provides security and stability to farm income by protecting the farmers’ investment in crop production and then improves their risk bearing capacities. Crop insurance scheme is based on the fundamental principle of insurance business in which risk is distributed across space and time. For successful implementation of any crop insurance scheme operating presently in the country, proper monitoring of accurate weather parameters at the identified locations throughout the crop life cycle is important.

Introduction

Data input or capture is the operation of encoding the data and incorporating in the database. The creation of a clean error free digital database is a complex and critical task determining the very usefulness of a GIS. GIS data represent not only where the graphic or cartographic features occur, but also the associated attributes of them.

Data input to a geographical information system involves

(a) Entering the spatial data (digitizing);

(b) Entering the non-spatial, associated attributes and

(c) Linking the spatial to the non-spatial data.

At each stage necessary verification and checking procedures shall be deployed to ensure an error free database.

Many types of geological hazards namely, tsunami, earthquakes, tsunami, floods and drought affect coastal areas like any other place on the Earth. As coastal regions are thickly populated and have abundant urban, industrial and recreational establishments, impacts of geohazards are always severe along coastal regions. Compliance to coastal zone regulations, with protection of sanddunesandmangroveswillbe the best mechanism to minimizethe damages from such hazards. In future, climate change may result in more hazards such as erratic rainfall and increase the frequency of droughts, floods and storm surges, etc. In this context, proposed coastal management zone for the coastal protection, disaster mitigation and management tools in coastal areas are examined in this chapter. It is suggested that extensive use of GIS and development of Geodatabase for the risk prone areas will serve as efficient tool for planners and policy makers to deal with geological hazards. In addition, it is felt that more efforts are needed in legal and institutional framework for integrated disaster management planning on local as well as national level.

INTRODUCTION

Geologic hazards are natural geological processes that inflict severe damage in areas of their operation if the area is utilized by anthropogenic activity in terms of habitation, industrial, recreational or commercial establishments. Many a times, natural geological processes that operated uninhibited for millions of years turn into geological hazards due to human intervention. These losses – lives and economic are not evenly distributed and are more prevalent in the developing countries due to higher population concentration and low level of economic growth. United Nations had realized the need of reducing these losses due to natural disasters and declared the last decade (1991-2000) as the International Decade for Natural Disaster Reduction. Objective of this proclamation was to reduce, through concerted efforts, the loss of life, property damage and socio-economic disruption caused by the natural disasters particularly in the developing countries (Tewar, 2000).

Introduction

The term geographic information systems (GIS) has come to mean, variously, an industry, a product, a technology, and a science. As such, the term invokes different perceptions dependent on whether the viewpoint is that of the software developer, the system marketer, the data provider, the application specialist, or the academic researcher, among others. A newcomer to the field is likely to be bewildered by the multiple uses of the same term, or, seen alternatively, different definitions of the same term. For instance some find it distasteful to use of the conventional acronym GIS and prefer Geospatial Technology. With all the variety of perceptions predicting the future of GIS is a cumbersome business. The most certain inference we can gain from the available trends is, it is growing and is poised for further growth. Geotechnology along with Nanotechnology and Biotechnology is considered as of the three most promising growth industries for the near future.

Research methodology is a way of explaining how a researcher intends to carry out their research. It’s a logical, systematic plan to resolve a research problem. A methodology details a researcher’s approach to the research to ensure reliable, valid results that address their aims and objectives. It encompasses what data they’re going to collect and where from, as well as how it’s being collected and analyzed. The deliberation on the methodology has been made to understand the concept, methods and techniques which are utilized to design the study, collection of information, analysis of data and interpretation of the f indings for the revelation of truths and formulation of theories. This chapter deals with the method and procedure used in the study and consists of eight main parts

• Locale of research

• Pilot study.

• Sampling Design.

• Empirical measurement of the Independent and Dependent variable

• Preparation of interview Schedule.

Introduction

Famous French postmodern philosopher Jean Baudrillard commented on information once. “Information can tell us everything. It has all the answers. But they are answers to questions we have not asked, and which doubtless don’t even arise.” This seemingly paradox observation fits contemporary Internet age perfectly. Internet is a vast repository of information of all kinds and is bursting on its seams. The seeker needs to search with monumental grit and determination to have a full handle on the range of information available for any particular search. A search string for GIS returns more than 1185000 results, in a mere 0.26 seconds. Recommending a comprehensive resource list is not possible as new material gets continually added by way of additions and updates. However for a beginner the list given below will be handy. The flip side is GIS has innumerable resources and a broad range of content. Software vendors, organizations, individuals, universities and companies have provided a wealth of information. The readers are exhorted to make use of the materials to improve their understanding of the subject.

7.1. Summary

The present research had been carried out to study the social ecology of arsenic contamination in groundwater; factors, perception and impact on life and livelihood of the selected village of West Bengal and in the end the comparison is made. The study had been conducted at village Mitrapur in the Haringhata block of West Bengal. A pilot study was conducted to understand the area, its people, institution, communication and extension system of these states.

An exhaustive list of respondents was prepared critically with the help of some villagers. From the list, 70 respondents from the village were selected for the study through a non-random snowball sampling method. The primary data were collected with the help of a structured interview schedule by following the personal interview method. The secondary data were collected from our departmental library, internet, Department of Agriculture, West Bengal, Bidhan Chandra Krishi Viswavidyalaya etc. for establishing the conceptual framework of the study.

Three types of Issues are Covered in this Study

• The influence of social, cultural, and/or economic variables on how drinking water poisoned with arsenic affects people’s life, notably their health (for example socio-economic patterns of illness and social),

• Social factors influencing people’s response: especially in relation to other priorities, perceptions of arsenic, and social roles and relationships.

The Imperative for Regional Collaboration Climate change poses a transboundary threat that no single nation can address in isolation. In CMCs, rural populations, often dependent on agriculture and natural resources, are disproportionately vulnerable. For instance, Assam, India, faces rising temperatures and frequent floods, threatening 86% of its agriculture-dependent rural population. Similarly, Bangladesh, a climate change hotspot, grapples with salinization and cyclones that disrupt rural livelihoods. Regional collaboration offers a pathway to pool resources, share expertise, and develop scalable solutions. As the United Nations Economic and Social Commission for Western Asia highlights, collaborative action enhances food and water security through shared knowledge

Allium vegetables, which include onions, garlic, and shallots, are a fundamental part of Indian cuisine and play a vital role in the country’s agricultural sector (Fig. 7.1). Here’s an overview of their importance, area, and production in India:
• India is the second-largest producer of onions in the world, accounting for over 20% of global production. Onions are grown across various states, with Maharashtra, Madhya Pradesh, and Karnataka being the top producers. The country produces over 19 million tons of onions annually, with a significant portion being consumed domestically.
• Garlic is another essential Allium crop in India, with the country producing around 1.4 million tons annually. The major garlic-producing states in India are Madhya Pradesh, Gujarat, and Maharashtra.
• Shallots are also grown in India, particularly in the states of Maharashtra, Gujarat, and Tamil Nadu. The country produces around 0.7 million tons of shallots annually.
• The importance of Allium vegetables in India extends beyond their culinary uses. They are a significant source of income for millions of farmers across the country. The Allium crop industry also provides employment opportunities in rural areas, contributing to the country’s economic growth.

3.1 Introduction

Crystallography is the science of crystals. The term crystal is derived from the Greek word “Crystallos” which means “ice”. The term was used for colorless quartz which was believed to be “fossilized” ice. Crystals are bodies bounded by flat surface, arranged on a definite plan which is an expression of the internal arrangement of the atoms. They are formed by consolidation of magma which is also considered as crystallization.

3.2 Terms in Use to Describe a "Crystal"

3.2.1 Faces

Faces are the plane surface in a crystal. The common faces are usually parallel to net planes containing the greatest number of lattice points or ions. Wide spacing between the net planes leads to development of faces in these planes. Faces are two types like and unlike faces.

Introduction

The Intergovernmental Panel on Climate Change (IPCC) assessment reports (IPCC, 2007) suggests that consequently occurring climate extremes are likely to increase the frequency and intensity in the future. In the Indian context, events such as landfall of rare of rarest most intense pre-monsoon Tropical cyclone Fani (2019), back to back landfall of very intense tropical cyclones such as Phalini (2013) and Hudbud (2014), Cyclone Komen (2015), Extreme rainfall events of Kerala (2018 and 2019), Heavy rainfall events of over Northeastern states of India (2019), Cloud burst events of Uttarakhand (2013), Rainfall over Himachal Pradesh (2019), Mumbai Rain fall (2015) and extreme heat wave conditions of 1998, 2015 and many similar type of extreme events are not usual. However, at present there is no unanimity among scientists to exclusively and directly link such extreme weather events to climate change, however based on number of studies and observation data sets it is agreed that the impact of climate change is evident (beyond the natural variability) in many part of the globe including India. In 2019 monsoon season at least 1351 deaths happened to ?oods, heavy rainfall and landslides compared to 1550 for year 2018. In this manuscript, recent research findings related to extreme weather events in the context India are discussed in the following section-2, need for high resolution and long term data sets are emphasized in section-3, followed by recommendations as part of future preparedness, that will not only enable us to address these issues in a robust scientific manner but also provide us strong resilient society to face these extreme weather events in an optimized and effective manner to minimize the loss of lives, properties and socio-economic conditions of citizens.

Since meteorology and climatology are primarily observational sciences, adequate care has to be taken for getting most representative and accurate observations of weather parameters for their efficient application. This depends on site of observatory, maintenance of observatory, accuracy of instruments, timely measurements of weather parameters, knowledge and responsibility of the observer.

Monitoring of weather conditions, in a country like India, which is climatologically so diverse because of its unique geographical situation is a challenging task. It is done through a large network of observatories of different types. India Meteorological Department (IMD), Pune, is entrusted with the collection and keeping the record of weather data collected from different stations and also to train the man power in this specialized area. Weather stations installed in different parts of the country are of different types.

ABSTRACT
There is a quantum global growth in both number and size of dairy industries in recent times. These industries discharge thousands of liters of wastewater characterised by a heavy chemical oxygen demand (COD), biological oxygen demand (BOD), nutrients, inorganic salts, besides detergents and sanitisers each day (Kushwaha et al., 2011). High carbohydrates, fats and proteins contents in such waste streams originating from milk pose challenge to conventional municipal sewage treatment systems (Demirel et al., 2005). The easily biodegradable dairy effluent leads to precipitation of casein which is toxic and has a strong odour. Without adequate treatment, these effluents could pose serious threats to the receiving water bodies and disturb the ecosystem (Satpathy et al., 2017). For such heavily loaded organic effluents, biogasification through anaerobic digestion seems a promising strategy. This cost-effective energy generation process is also effective in environmental management compared to its other eco-friendly renewable source counterparts, such as, hydro, solar and wind (Satpathy, 2017). The Upflow Anaerobic Sludge Blanket (UASB) reactors are the most popular anaerobic systems to treat the fluctuating organic loads in dairy effluents. Anaerobic filter (AF), Upflow Anaerobic Filter (UPAF), Fixed-bed anaerobic reactor, Anaerobic Hybrid Reactor (AHR) etc. are few other systems that are demonstrably competent removing COD upto 90% and generating biogas. Successful anaerobic systems reported yielded (with upto about 85% CH₄ content) 0.32-0.34m3 CH₄/kg COD removed. Biomethanation process and reactors designs are constantly being optimised for effective treatment of the effluents while maximising the biogas production. The energy-rich gas thus obtained could further be utilised for heat and electricity at the domestic level, and also as a vehicular fuel. Residual digestate can also be used as organic manures (Angelidaki et al., 2007).

Introduction

Climate change is one of the biggest environmental threats to food production, water availability, forest biodiversity and livelihoods. Warming of climate system of the earth is a unanimously accepted reality and probably one of the most prominent challenges for scientists, development workers, policy makers and other relevant stakeholders regarding development and sustainability in international and national arena during past several years. Intergovernmental panel on climate change (IPPC) has described climate change as any anthropogenic or naturally occurring alteration in the climate over time. It is widely believed that developing countries such as India will be impacted more severely than developed countries. Climate change is emerging as a big threat to sustainable development of agriculture including animal husbandry and to the livelihood of people. Extreme events such as cold waves, heat waves, ?oods and high intensity single day rainfall events are on increasing trend during the last decade (Dikshit and Birthal, 2010). It is probable that by 2030 the impacts of climate change will be noticeable, although not dramatic and will be largely manifested through changes in pasture growth and quality, and greater inter-annual variability in pasture production. Livestock contribute to climate change by emitting methane through enteric fermentation. But they are also affected by climate change it directly and indirectly, hence affecting their economic and social contributions. Various studies suggest that the changes in pasture growth, composition and production will be dependent on the actual combination of CO₂, temperature and rainfall conditions. Livestock productions under both intensive and extensive systems are subjected to so many stresses, where they undergo different types of physiological adjustments to cope up with stressful conditions. Productions are drastically reduced during stress and require managemental interventions both in terms of optimum nutrition and health care (Soren, 2013).
