Abstract

Leadership behavior is seen in every group of social animals like elephant, honey bee, human being, etc. Initially people thought this behavior as inborn character and only few lucky people possessed it. But now it has been proved that this character can be developed by interested people through systematic training. In every family parent are playing the role of either leader or manager and being a role model gradually transmitting this behavior to their children from childhood itself. Training begins at home of every successful leader.  In this article the characteristic features of leaders, style of their functioning, leadership theories and the difference between a leader and a manager are discussed in details. Important tips have been mentioned to follow for becoming a good and successful leader.

Introduction

A geographic information system or geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In a general sense, the term describes any information system that integrates stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems.

GIS is a broad term that can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should, ideally, be relatable to one another and ultimately to a “real” physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry.

“Educational Technology is the application of scientific knowledge about learning and the conditions of learning to improve the effectiveness and efficiency of teaching and training. In the absence of scientifically established principles, educational technology implements techniques of empirical testing to improve learning situation”.

The most recent definition of the field (which uses the term, instructional technology) has been published by the Association for Educational Communications and Technology (AECT). It defines Instructional Technology as “the theory and practice of design,

Participatory technology development (PTD) is an approach to learning and innovation that is used in international development as part of projects and programmes relating to sustainable agriculture. The approach involves collaboration between researchers and farmers in the analysis of agricultural problems and testing of alternative farming practices.

Origins of participatory technology development

The origins of Participatory Technology Development can be found in a number of approaches, concepts and techniques that became popular in the 1970s and 1980s:

Farming systems research and extension, an approach that introduced social-ecomomic issues into organisations previously dominated by biological and chemical scientists. FSR/E also promoted the idea on ‘on-farm’ trials:

Appropriate technology, a concept that recognises the importance of matching the design of technology to the resources and culture of the user.

Access to information and improved communication is a crucial requirement for sustainable agricultural development. Modern communication technologies when applied to conditions in rural areas can help improve communication, increase participation, disseminate information and share knowledge and skills. It is being said that “Cyber Extension” would be the major form of technology dissemination in the near future. However it is observed that the rural population still have difficulty in accessing crucial information in order to make timely decisions. It is essential that information availability is demand driven rather than supply driven. The challenge is not only to improve the accessibility of communication technology to the rural population but also to improve its relevance to local development.

The advent of INTERNET on communication scenario offers enormous potential for two-way on-line communication between distant parties via the telecommunication and computer network spread over the entire globe. The world is rapidly shrinking to a ‘global village’ which some courageously even call a ‘global family’. The merger of communication (audio and video) and computer technology has suddenly made this combination so powerful that no sector of human activity can afford to ignore it. Right from high security defense systems, space research, engineering and educational applications the INTERNET has found users in petty shopkeepers and small service agencies. In countries like Singapore, you can book a taxi via e-mail and the concerned taxi driver is able to confirm your booking, while he is still driving.

Introduction

Over the last two decades the Land and Water Development Division (AGL) has been at the forefront of the development and application of computer-based systems to analyse data and generate information to support decisions on various land and water issues . Separate soil and land and water systems have been developed. The soil and land systems focus on methodologies and tools for the assessment of land resources potentials at global, regional and national and sub-national levels. The water systems concern irrigation water use and management at field level and water resources assessment at regional and national levels.

AGL has been cooperating with various units within FAO and numerous international agencies and national institutions in developing and applying the systems.

Initially, in the late seventies and early eighties, the systems were developed for mainframe and mini-computers. From the late eighties they were gradually adapted to microcomputers. At the same time computer tools for managing spatial data, including geographic information systems (GIS), remote sensing and global positioning systems (GPS) were introduced. Since the last few years the availability of networked PC workstations, rapid application development environment and multimedia tools have opened an era of completely new possibilities in the development and application of the systems.

Introduction

Glaciers are large masses of snow, re-crystallized ice and rock debris that accumulate in great quantities and begin to flow outwards and downwards under the pressure of their own weight. Glaciers form when yearly snowfall in a region far exceeds the amount of snow and ice that melts in a given summer. In this way, massive quantities of glacial material accumulate in relatively small periods of geologic time. The glaciers exist in environments of high and low precipitation and in many temperature regimes; they are found on all the continents except Australia and they span the globe from high altitudes in equatorial regions to the polar ice caps. Presently, 10% of the Earth’s land area (5.8 million square miles) is covered with glaciers storing about 75% of the world’s freshwater. However, during the last Ice Age, glaciers covered 32% of the total land area of the planet.

Introduction

The availability of land and water resources has a major effect on the economic and ecological aspects of life everywhere around the world. As a result, the need to develop better tools for efficient land and water resources management has become very vital. For quicker, reliable and precise results, it is necessary to use the geospatial tools and techniques such as Global Positioning Systems (GPS), Geographic Information Systems (GIS) and Remote Sensing (RS) image interpretation and analysis techniques to manage the natural resources. The application of these tools and techniques not only facilitates timely and repetitive analysis of all the topological features, but also assists in development of Decision Support Systems (DSS) to generate alternative scenarios for optimal use of the natural resources in the long term. The optimal use of these resources through integrated management of land water and vegetation leads to enhanced production and productivity of food, fodder, fiber, fuel, fish, flower and forest resources. Moreover, the holistic management of the resources to produce these outputs is plausible and manageable within the watershed systems, which are hydro geological units from which the runoff resulting from precipitation flows past through a single outlet to downstream locations. The systematic management of land, water, vegetation and livestock resources within the watershed systems is termed as Integrated Watershed Management (IWM). Broadly, IWM can be defined as a multidisciplinary, holistic way of protecting and managing a watershed’s natural resources to enhance biomass production in an eco-friendly manner. The watershed is viewed as a hydro-geological complex and dynamic ecosystem in which natural and anthropogenic processes occur and interact resulting in generation of runoff at the watershed outlet.

3.1 INTRODUCTION

Geographic Information System handles large volumes of data. It is important to know the nature of data, instruments from which the data is collected and represented in computers. GIS data is either spatial or aspatial. Data is an important component in GIS. Digital data are available for some projects. but for many projects, input data may not be available. Now-a-days, data is supplied by many government, private organizations and also available on internet. If data for a particular project is not available, then the user has to collect the data from satellite imageries, GPS and other instruments and maps from various sources.

Spatial Data

All locations in the earth surface are spatial data. Location of a city, location of a river, location of a lake are represented in earth by their latitude or longitude in global coordinate system or as x,y coordinate in Cartesian coordinate system. Spatial data consists of location, shape and size in earth. A village boundary is represented as a polygon in map. The village is having certain shape of irregular polygon with definite area. As all these are mappable , they are called as spatial data. But name of the village, revenue of a village and description about a village and called as non-spatial or aspatial data.

Abstract

Carrying out effective and sustainable agriculture has become an important issue in recent years. A key to this is the usage of modern technologies for precision agriculture. Recent technological developments allowed envisioning sensor devices with distributed ambient sensory network, which could be a potential technology for monitoring various natural phenomena (weather parameters, soil moisture, etc.) at micro level. As more and more agricultural data are virtually being harvested along with the crops and are being collected/ stored in databases, the same can be used in productive decision making if appropriate data mining techniques are developed/applied. As a case study for this, an experiment was conducted with four consecutive agricultural (Kharif and Rabi) seasons in a semi-arid region of India to understand the crop-weather-environment-pest/diseases relations using wireless sensory and field-level surveillance data on closely related and interdependent pest/disease dynamics of groundnut crop. Association rule and multivariate regression mining techniques/algorithms were propose developed /tailor-made to turn the data into useful information/ knowledge/relations/trends to know crop-weather- environment-pest/disease continuum. These findings have been used for development of prediction models (cumulative and non-cumulative) followed by a web based pest/disease decision support system.

4.1 Introduction

The present chapter starts with a brief description about the history of commodity futures market and emergence of commodity futures market in India. There after it highlights various functions of commodity futures market and their impact on farmers and various other stake holders in the supply chain. Finally, it tries to evaluate the utility of futures from the platform of commodity exchanges especially from MCX and NCDEX of India.

A simple definition of a commodity is a physical substance that can be extracted directly from the environment, processed and sold commercially. Natural resource is another term often used to describe commodities which occur naturally in or on the ground. Commodities fall into three main categories such as energy, metals and agriculture. As commodities can be sold, they have a price which is governed by supply and demand. Compared to many manufactured items, for example flat screen TVs, the question of supply and demand is paramount to how commodities are priced. The commodities that have always been a part of our day-to-day existence are also one of the finest investment avenues available. The wheat in our bread, the cotton in our clothes, our gold jewels, the oil that runs our vehicles etc are all traded across the world in major exchanges. Commodities can be traded on either spot markets, or in the form of futures. Spot markets are those in which the commodity is traded immediately in exchange for cash or some other good. In the form of futures (or options), what is traded is not the goods itself, but a contract to buy or sell the commodity for a certain price by a stated date in the future. Over the ages, commodities have been the basis for trade and industry. They have prompted commerce, encouraged exploration and altered the histories of nations. Today, they play a very important role in the world economy with billions of dollars of these commodities traded each day on exchanges across the world. Commodities today have become an attractive investment vehicle. In the current investment scenario, it is increasingly getting difficult for individuals and institutions to create a well-balanced investment portfolio. With uncertainty in interest ratio, it is tough for the investor to beat the ever-rising inflation. Averse to being over exposed to equity markets, the investors are left with limited choices… well no more!

Entrepreneurial climate depends on the existing economic system. Existing social and political establishment and existing economic policies of Government determine the economic system. Entrepreneurial development is largely due to the existence of this economic system. Business development functioning as a new component, economic structure and economic transformation. The economic system varies from country to country, so the business development process varies.

Introduction

India has been an agricultural economy since its inception. Several mechanisms are used in agribusiness, such as forward and backward linkages with secondary and tertiary sectors, such as manufacturing and service sectors. Opportunities in agriculture and related sectors can be identified at various stages of the farming process. Generally, agribusiness opportunities exist at the input stage, the farming stage, the value chain, the output processing and marketing stage, and the related services stage. As a result of globalisation and a more interconnected global market, the scope and potential of agribusiness opportunities is expanding. For entrepreneurs, there are numerous potential opportunities. Many different inputs are required in the agricultural process, such as seeds, fertilisers, pesticides, and innovative and localised farm technology. As a result, the aforementioned areas create agribusiness opportunities in developing and producing these inputs.

4.1 Introduction

With the birth of the new millennium and the advent of Information and Communication Technology, the outlook of academia towards research has completely metamorphosed into a more productive and vibrant activity. Digitalization of data, the convergence of new and challenging insights in one’s own research fields at the world-wide-web and technology generation are being made faster and more reliable. With the arrival of Laptops and Smartphones simultaneously with the facility Wi-Fi, the demand for information of any kind has become unquantifiable! The academic world is no exception, indeed! Such a pang of hunger for information led to considerable investments in infrastructure development. The virtual, electronic, automated world became inseparable from academic and research institutions. Small wonder that with these, the pressures on the institutional and specialized and dedicated libraries are on the increase.

4.1 Introduction

In many surveys, information on an auxiliary (supplementary, ancillary or apriori) variable x, which is highly (positively or negatively)correlated with the variable y under study, is readily available and can be used for improving the sampling design. Stratified sampling and probability proportional to size (p.p.s) schemes are two examples of improved sampling designs, in which the use of data on auxiliary variable has been made. However in both the schemes, it implies that the information on auxiliary variable on individual sampling units is available prior to presentation of sampling design. In case, data on auxiliary variable for individual sampling units are not available but only the aggregate value for all units of auxiliary variable is available, the two schemes can not be used. In such a situation, the aggregate data on auxiliary variable can still be used at the time of estimation of parameters under consideration, provided the data on auxiliary variable for the sampled units can be easily obtained at the time of recording the values of the study variable.

12.1 Introduction
Having explored the dynamic realm of Numerical Weather Prediction, which focuses on forecasting the atmosphere’s state over days to weeks, we now shift our focus to a broader, longer-term perspective: Climate Data and Analysis. While weather describes the atmospheric conditions at a specific place and time, climate refers to the long-term average pattern of weather in a region, typically spanning decades or longer. Understanding and analyzing climate data is paramount for comprehending our planet’s past climate, identifying ongoing changes, and projecting future scenarios in a warming world. The study of climate is fundamentally data-driven. Unlike the instantaneous snapshots used in weather forecasting, climate analysis requires vast historical records, often extending back centuries or even millennia, to discern natural variability from human-induced changes. This data comes from a diverse array of sources, including instrumental records (thermometers, rain gauges, barometers), satellite observations, and proxy records (tree rings, ice cores, sediment layers) that provide indirect evidence of past climate conditions. The sheer volume and heterogeneous nature of this data present unique challenges and opportunities for analysis.
This chapter will delve into the essential aspects of climate data and the methodologies used to analyze it. We will begin by exploring the various types of climate data available, understanding their strengths, limitations, and how they are collected and curated. Crucially, we will examine how this data is used to characterize climate variability – the natural fluctuations within the climate system – and to detect climate trends, particularly those associated with global warming. We will introduce key climate indices that summarize large-scale atmospheric and oceanic patterns, providing simplified metrics for
understanding complex interactions.

Introduction 
India’s digital transformation over the past decade has emerged as a defining feature of its governance and developmental strategy, propelled by the ambitious Digital India initiative launched in 2015 by the Ministry of Electronics and Information Technology (MeitY). With a vision to transform India into a digitally empowered society and knowledge economy, the initiative seeks to harness the power of information and communication technologies (ICT) to make governance inclusive, efficient, transparent, and responsive. Digital India marks a paradigm shift in how public administration operates, embedding technology at the core of policy delivery, citizen engagement, and institutional coordination across sectors and tiers of government. Creating a robust and scalable digital infrastructure is at the heart of this transformation. Major projects like BharatNet aim to connect 2.5 lakh Gram Panchayats via high-speed optical fiber, of which over 1.5 lakh were connected by 2020. Simultaneously, establishing more than 3.7 lakh Common Service Centres (CSCs) has extended digital service delivery to rural and remote areas. These CSCs function as inclusive access points, offering health, education, agriculture, banking, and public utilities services in a culturally and linguistically localized format, catalyzing rural digital entrepreneurship and last-mile inclusion. India’s approach to digital governance extends beyond infrastructure to encompass citizen-centric digital services and platform-based public service delivery models. Platforms such as UMANG, eHospital, BHIMUPI, DigiLocker, eCourts, Tele-Law, and eWay Bills have simplified citizen interaction with the state, enhancing the ease of living and improving administrative efficiency. The Government eMarketplace (GeM) has transformed public procurement by making it more transparent, efficient, and accessible for small businesses and start-ups. The Jan Dhan–Aadhaar–Mobile (JAM) trinity has revolutionized welfare delivery by facilitating Direct Benefit Transfers (DBT) into verified bank accounts, eliminating intermediaries, and saving over ?1.7 lakh crore by 2020.

Group dynamics and formation represent fundamental processes in community mobilization that determine how individuals come together to form collective entities capable of achieving shared goals while building social capital and institutional capacity that can sustain long-term community development efforts. Understanding these processes provides essential insights into how communities can organize themselves effectively while creating groups that can navigate complex challenges and maintain cohesion through the inevitable difficulties and conflicts that arise during collective action initiatives. The science of group dynamics encompasses the complex social, psychological, and organizational factors that influence how groups form, develop, function, and achieve their objectives while building understanding of the internal processes that enable or constrain group effectiveness and sustainability. This knowledge has evolved through decades of research in social psychology, organizational behavior, and community

Modern farm planning involves nonlinear, discontinuous and multi-objective problems that conventional optimization methods may not solve effectively. This chapter examines Genetic Algorithms, Particle Swarm Optimization and Differential Evolution for improving agricultural resource allocation. These nature-inspired techniques can simultaneously address crop yield, water use, fertilizer application, environmental effects and financial viability. Their integration with deep-learning forecasts and crop-simulation systems enables more realistic optimization. Multi-objective evolutionary algorithms identify Pareto-optimal alternatives, allowing decision-makers to balance productivity and ecological sustainability. The chapter also emphasizes explainable artificial intelligence, economical implementation and farmer usability as necessary conditions for transferring evolutionary optimization methods from experimental research to practical farm management.

Artificial intelligence is becoming an important technology for transforming agricultural decision-making and farm management. This chapter introduces the fundamental concepts, tools, and applications of AI in agriculture. It explains how machine learning, deep learning, computer vision, predictive analytics, and intelligent systems can process large volumes of agricultural data. AI applications include crop monitoring, disease detection, yield prediction, precision input management, and automated decision-making. The chapter also discusses the major drivers of AI adoption, including increasing food demand, resource constraints, climate change, and labour shortages. Examples of AI-based agricultural applications demonstrate its potential to improve productivity, sustainability, resource efficiency, and resilience.

1. Country Background

India is one of the oldest civilisations in the world with rich cultural heritage. India has become self-sufficient in agricultural production, and is now the tenth industrialised country in the world. It covers an area of 32,87,263 sq km. Lying entirely in the northern hemisphere, the mainland extends between latitudes 8°4' and 37°6' north, longitudes 68°7' and 97°25' east, and measures about 3,214 km from north to south between the extreme latitudes and about 2,933 km from east to west between the extreme longitudes. 
Agriculture is the mainstay of the Indian economy, as it constitutes the backbone of the rural livelihood security system. It is the core of planned economic development in India, as the trickle-down effect of agriculture is significant in reducing poverty and regional inequality in the country. Growth in agriculture has a maximum cascading impact on other sectors, leading to the spread of benefits over the entire economy and the largest segment of population. 141 million hectares is the net sown area, while 190 million hectares is the gross cropped area. The net irrigated area is 57 million hectares with a cropping intensity of 134 per cent. Eighty-two per cent of farmers have small and marginal land holdings.

Computational crop-disease detection uses machine learning, neural networks and image-processing techniques to provide timely and accurate diagnoses. This chapter presents a complete framework covering agricultural intelligence, disease categories, image acquisition, preprocessing, model training and classification. It examines datasets collected in fields or through drones and considers deployment through mobile devices, cloud platforms and other digital systems. Evaluation measures are introduced for assessing model accuracy and reliability. The chapter also considers limitations caused by insufficient or poor-quality data and variation in field conditions. Future directions include multimodal data integration and explainable models that provide transparent recommendations for sustainable crop protection and improved food security.

The vision 2020 document of the Department of Agriculture and Co-operation envisages that “the tools of ICT will provide networking of Agriculture Sector not only in the country but also globally and the Centre and State Government Departments will have reservoir of databases” and also “bring farmers, researchers, scientists and administrators together by establishing ”Agriculture Online” through exchange of ideas and information”. To get realize the vision 2020 a large number of agriculture based websites and web portals have been established in India which is working for wellbeing of farming community. Majority of agricultural websites and web portals are providing need based technological information to the farmers as well as extension professionals. To revitalize our extension system these web based services can be used as ICT tool by extension personnel and farmers also. Therefore, to get access services from these websites and web portals or to replicate these ideologies in other part of country, elementary knowledge of working process and services available on these websites & web portals is essential. This chapter will provide a brief description about major ICT based projects dedicated to Indian farmers.

1. Introduction

Afghanistan imperiled by decades of war, is  now a country on the rebound. With the days of relative peace up on the Afghan people, resources are being gathered and projects put onto place, in an effort to revitalize the previously stagnant economy. The rehabilitation of the agricultural economy in Afghanistan depends to a large extent on whether Afghanistan’s Agricultural Sector will be able to recover from the effects of war, serious consecutive droughts and a multitude of endemic crop/ livestock diseases. Afghanistan is a pastoral country with more than 85 per cent of the land area incapable of growing even a narrow range of crops, thus being largely rangeland.  Agriculture produces food, provides food security, enhances crop production, generates cash incomes for rural and urban populations, provides fuel and transport, and produces value added goods which can have multiplier effects and creates a need for services.  Furthermore, agricultural diversity production and income provide year-round employment, and spread risk. Livestock also form a major capital reserve of farming households.

1. Country Background

Mozambique is a country that is extremely dependent on agriculture, both for rural livelihoods and for overall economic growth. This importance is illustrated by the following:
    •    The agriculture sector accounts for about 20  per cent of GDP1.
    •    80  per cent of total employment and higher in rural areas.
    •    55  per cent of household incomes (national average) adding self-consumption and income from selling agricultural products2.
    •    40  per cent of export earnings (2003).
    •    The economy is not diversified and the average level of education is low, with few options for finding non-farm employment and incomes in rural zones.

1. Basic Information

Philippines  is located between 4o23’N and 21o25’N latitude, and between 116oE and 127oE longitude. It is an archipelago of 7,107 islands with three major groups of islands: Luzon, Visayas and Mindanao. It is bounded by the Bashi Channel up north, Sulu and Celebes Seas in the south, the Pacific Ocean to its east, and the South China Sea to its west. The Philippines has a tropical climate with an average temperature range of 23° to 32°C. Populated by 88 million people, the country has a total land area of 3,00,000 square kilometers  (30 million hectares); where about one third is agricultural land (NSO, 2007).

Of the agricultural land, 31 per cent is used for cereals such as corn and rice, 52 per cent for food crops and 17 per cent for non-food crops (ITC, 2007). Majority of these are cultivated on small farms averaging about two hectares and are managed by single families ranging from subsistence to commercial production (NSCB, 2007).

Key words : Remote Sensing, Ecosystem, Environmental Pollution, Biodiversity Conservation, Coastal Environmental Degradation, Wetland.

Introduction

National prosperity and human resources development are primarily shaped by the availability of natural resources and their use. None the less, the benefits are quite often negated by the resultant environmental degradation concomitant with their utilisation for economic values. The problems of environmental degradation have assumed critical dimensions in many parts of India due to resources exploitation; industrialisation and urbanisation, unchecked population growth and a never ending quest for energy to meet the increasing demands. Moreover, improper utilisation of resources has resulted in such environmental problems as soil erosion, waterlogging, floods, droughts and pollution of various types besides socio-economic disparity among people.

After the 1972 Stockholm conference on Human Environment and Development, there has been a phenomenal increase in the worldwide interest in the environmental issues associated with development. Consequently, the focus of development has shifted to environment friendly and sustainable developmental planning in recent years. The Rio Summit (June 3-14, 1992) further emphasised the fact that earth is an integral and interdependent system, which require sustainable developmental planning. During deliberations of the Rio Summit (Earth Summit), it was emphasised that satellite imagery will be quite helpful in monitoring earth’s environment.

India has a long tradition of environmental protection and has enacted laws during the last three decades to give further impetus to the conservation of natural resources and protection of environment. Some of the important laws are:

There are many countries surrounded by the waters of the Caribbean Sea. These countries vary widely in size, topography, ethnicity, language spoken, agricultural production systems, main sources of income, income levels and styles of governance, to name a few.

This analysis covers only the countries where English is spoken as the first language. These countries are linked through a grouping of Caribbean Communities, called CARICOM, an organization of 15 Caribbean nations and their dependencies. It starts with Jamaica in the North to Trinidad and Tobago in the South, but also includes Belize in Central America and Guyana and Suriname in South America. Although French speaking Haiti and Dutch speaking Suriname belong to CARICOM, they are not discussed because of the language barrier. The other French speaking islands (Guadeloupe and Martinique) and the Spanish speaking islands (mainly the Dominican Republic, Cuba and Puerto Rico) have different administrations for agricultural development. CARICOM countries stretching from the tip of Florida, USA, in the North to Venezuela in South America. CARICOM includes Belize in Central America and Guyana and Suriname in South America.

1. INTRODUCTION

In the past, conventional ICTs that have been applied to agricultural extension services include the use of television, radio, etc., and these media have been criticized as archetypical, passive, top-down in nature; hence they have not created meaningful impact on agricultural information delivery (Akpabio, 2007). As a result of this, extension roles have undergone several transformation, over the years. One of the objectives of agricultural extension is to create conducive platform for empowerment so that food security can be guaranteed. In order to guarantee food security there is need to utilize faster and more efficient techniques of project identification, selection, implementation and evaluation in the agricultural extension process (Braimoh and Oladele, 2000). The inadequacies of interpersonal communication strategy in development gave credence to the use of media support in development process (Yahaya, 2000). In recent times, further improvements have been made on the use of media support through digital media. This is what makes contemporary ICT more relevant.

Modern ICTs emerged in Nigeria at a time when there was need for change in the agricultural extension delivery system to suit the contemporary situation. The conventional forms of communication used by extension agents include written (bulletin, leaflets, newspapers, articles, personal letters, circular, etc.); spoken (general meeting, special meeting, farm and home visit, official calls, telephone calls and radio); visual (result demonstration, exhibits, posters, motion pictures, charts, slide) and spoken/visual (method demonstration meeting, result demonstration meeting, meeting involving motion pictures, meeting involving charts).Torimiro et al.,(2000) noted the non-usage of telephone calls in extension work, giving reasons as preference for the locally accessible and affordable forms of communication they can employ.

Manure is the organic material derived from animal, human and plant residues which contain plant nutrients in complex forms. Manures are used as source of plant nutrients. They release nutrient after their decomposition. They are applied in large quantities

Advantages of Organic Manures

• Organic manure provides all the nutrients that are required by plants but in limited quantities.
• It helps in maintaining C:N ratio in the soil and also increases the fertility and productivity of the soil.
• It improves the physical, chemical and biological properties of the soil.
• It improves both the structure and texture of the soils.
• It increases the water holding capacity of the soil.
• Due to increase in the biological activity, the nutrients that are in the lower depths are also made available to the plants through manures.
• It acts as mulch, thereby minimizing the evaporation losses of moisture from the soil.

1. Introduction

The advent of computers, the Internet and other ICT technologies have enhanced the nature of tasks. No one is immune from technology. Technologies have paved the way for information transformation. Today every section of society is making full use of technologies to fulfil their needs. Electronic devices have affected human life to a great extent. These devices have changed the working styles of human beings. Working with electronic devices is much better than manual work. Therefore, every sector of human working society is updating itself by using or implementing electronic devices. The higher education department is no exception to this. Today every sector of higher education department is using these modern tools and technologies not only for official works but also for teaching. Library is the most important part of Higher Education Institutions and today the entire structure of the library has changed. Today computersare being used in every section of the library and the main work of the library- issue/return is also being done through the use of computers and the Internet. The resources available in the library have also become electronic. Every resource like books, magazines, research journals, dictionaries, glossaries, bibliographies, biographies, who’s who etc, is now being published in electronic form and the library has to purchase these resources for its users.

Project managers need to make sense on the many data that they have. Analytical tools are used in project management to achieve such need. Such tools are used to create a forecast of potential outcomes based on the variations present in the environmental and project variables. There are different types of analytical tools used and one of the most common tools is regression analysis.

14.1. Multiple Regression

Concept: Multiple regression is the most commonly utilized multivariate technique. It examines the relationship between a single metric dependent variable and two or more metric independent variables. Multiple regressions are often used as a forecasting tool. Goal is to use the linear composite of two or more continuous and/or categorical variables (predictors) to: 1) predict scores on a single continuous variable (criterion), or to 2) explain the nature of the single continuous criterion variable from what is known about the predictor variables. In prediction, the criterion is the main emphasis because decisions are made on its value, but often times, it is difficult to directly measure or obtain a subject’s actual score on the criterion; therefore, it is important to estimate or predict one’s criterion score based on the value of the predictor scores.

The vulnerability of agriculture and livelihoods in the Member Countries of the Centre on Integrated Rural Development for Asia and the Pacific (CIRDAP) poses a significant threat to achieving climate- resilient rural development. CIRDAP includes 15 member countries: Afghanistan, Bangladesh, Fiji, India, Indonesia, Iran, Laos, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam [CIRDAP, 2023]. ]. In many Asian countries, agriculture is still practiced using traditional methods that do not incorporate climate data or modern techniques. This reliance leads to several challenges, such as reduced productivity and crop diversity, increased vulnerability to weather fluctuations, and hindrance in establishing resilient value chains. For example, in Iran's rural sector, challenges such as centralized planning, patriarchal norms, inefficient extension systems, and weak inter-agency coordination are uniquely defining features (CIRDAP, 2025). However, evidence shows these challenges are widespread across the region:

The chapter considers applications within Indian educational contexts, including curriculum alignment, digital platforms, low-bandwidth environments, and emerging institutional initiatives. It also discusses challenges such as teacher resistance, inadequate AI literacy, interoperability, infrastructure limitations, data privacy, and ethical concerns. Successful implementation requires human review and pedagogical judgment. The chapter ultimately presents AI as a curriculum co-design and teacher-augmentation tool capable of improving efficiency, personalization, scalability, and educational relevance.

Climate change and resource scarcity require farming systems that anticipate risks and make proactive decisions. This chapter explains how predictive modelling, artificial intelligence and IoT technologies can strengthen climate-smart agriculture. Statistical techniques, Convolutional Neural Networks, Long Short-Term Memory networks and Transformer models are examined for forecasting weather, crop performance and resource requirements. These tools can improve irrigation and fertilizer management, raise productivity and reduce environmental impact. Adoption remains constrained by poor-quality data, infrastructure deficiencies, cost, limited interpretability and unequal access to digital technology. Farmer-centred design, federated learning, gradual deployment and scalable systems are recommended for developing fair, practical and climate-resilient agricultural solutions.

Introduction

Mangroves are the special group of plants or the ecosystem in a holistic scence on the inter-tidal coastal areas, edges of the islands and major estuarine mouths. The frequently tidal inundated forests on coastal areas, wetlands and the inter-tidal zones of sheltered bays or shore lines, estuarine mouths, sides of the tidal creeks, backwater, lagoons, marshes and mud-flats of the tropical and sub-tropical regions of the Globe are the major mangrove habitats or zones. Mangrove ecosystem form an important ecological asset and economic resources of the coastal marine environment. These mangrove ecosystem is the most productive ecosystem, which can efficiently fertilize the sea and estuarine water and also physically protect the coastal zone, estuarine mouth from frequent natural calamities and vitally serves as the breeding ground, nursery and grazing place of diverse species of fish, shrimps, prawns, crabs and vast group of other marine and off-shore species.

In India, the agricultural research and technology generation are supported in five agro-ecosystems, viz. irrigated agro-ecosystem, arid agro-ecosystem, rain-fed agro-ecosystem, coastal agro-ecosystem and hill & mountainous agro-ecosystem. Each system with its varied socio-economic and agricultural features, demands appropriate technologies to augment the productivity of various enterprises with sustainable development and economic returns. Unfortunately, the conventional development efforts, which often follow “top-down” approaches in planning and implementation, don’t address the constraints and developmental potentials of farm household systems in a comprehensive way. To overcome these shortcomings, reversal of approach, i.e. from “Top down” to “Bottom up” is recommended. This can be achieved through site-specific assessment and refinement of technologies with farmer’s participation where the farmers of different agro-ecosystems have right to plan, implement and own their developmental projects (Johnkutty et al., 2001).

The research procedures followed in the study are reported under the following sub-heads viz. Selection of Farm Technology and Development of Farmer -Friendly Interactive Multimedia Compact Disc.

3.1. Selection of Farm Technology: Integrated Pest Management Practices for Coconut Eryophid Mite

3.1.1. Importance of Coconut

Coconut is one of the most widely grown plantation crops of the tropics. The palm is recognized as a multiproduct and termed as horticultural, plantation, food and even as an oil seed crop. It has diversified uses such as sources of food, drink and shelter and as a raw material for various industrial uses and thus serves as commercial crop.

The coconut is referred to as man’s most useful tree, synonymously the King of the tropical flora, tree of abundance, tree of heaven Kalpa Vrisha, tree of life and layman’s crop. Millions of people in India and other tropical regions depend upon the coconut plantations for their livelihood. More than 100 products are being made directly or indirectly from coconuts and their export earned India appreciable foreign exchequer.

Introduction

Precision Farming (PF) revolves around the idea that any agricultural land contains wide spatial variations in soil types, nutrient availability, and other important factors. If these variations are not taken into account, then there may be a loss in productivity. Precision farming is one of the most scientific and modern approaches to sustainable agriculture that has gained momentum in 21^st century. Consider the situation: ‘A farmer goes to his/her field with his/her Global Positioning System (GPS) guided tractor. The GPS senses the exact location of the tractor within the field. It sends the signal to a computer on the tractor that has a Geographical Information System (GIS), storing the soil nutrient requirements map in it. GIS, in consultation with a Decision Support System, decides what is the exact requirement of the fertilizer for a given location and then commands a variable rate fertilizer applicator, attached with the tractor, to apply the exact dose at that precise location. All this is done within a second, before the tractor moves further.’ This may sound like an excerpt from a scientific fiction, but this is what precision farming means to the large growers of the United States or European countries and day is not far off when it will be feasible for large Indian farmers as well.

PF refers to a developing agricultural management system that promotes variable management practices within a field according to site or soil conditions. Within a short span of time, this concept has been described with various names viz. farming by soil; farming soil, not fields; farming by the foot; spatially prescriptive farming; computer aided farming; farming by computer; farming by satellite; high-tech sustainable agriculture; soil-specific crop management; site-specific farming; and site-specific crop management.

Socio-economic impact assessment is an important activity that justifies the implementation and continuation of the project efforts and to enhance the observed ability of the project outcomes. there are several approaches available for assessment of the impact of project interventions. in the present investigation, before or after research design was used for impact assessment.

Socio-economic impact assessment activity, the benchmark survey boss carried out before the initiation of the project. The benchmark survey focused on the socio-economic profile of tribal households in the project area including the landholding, personal profile of the household head, household income, its sources, income source diversity. The survey also focused on the agronomical aspects like the productivity of major crops, cropping intensity and income generation from various farm activities. Further, in the benchmark survey, data was also collected on the aspects related to household food security. The findings of the benchmark survey are presented below.

We get energy from food. We need energy for all the activities which we get by eating. The body structures as muscles, organs and bones are composed of the nutrients contained in food which are absorbed by the body.

Nutritional requirement of the major nutrients

Nutrients are the substances which are found in food and drive biological activity. They are essential for the human body. These are categorized into proteins, fats, carbohydrates (sugars, dietary fiber), vitamins and minerals (Sugishima, 2019). They perform the vital functions like building all parts of the body as muscle, bone, teeth and blood. Out of the 20 different kinds of amino acids that make up proteins nine are not synthesized in the body and are therefore called essential amino acids. These essential amino acids have to be supplemented through food. High-protein, low-carbohydrate diets have been found to be effective.Protein is an important component of every cell in the body. Large part of hair and nails are made up of proteins. The human body uses protein to build and repair the tissues, helps in making enzymes hormones and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin and blood.

Research methodology is a systematic approach to solve any research problem and arrive at a conclusion that adds to the already existing fund of knowledge. The research methodology seeks to define the solution by adopting appropriate research techniques. They are generally applied during the initial stage of the study to delineate and outline the rationale for the chosen methods and their functionality and effectiveness towards achieving a decided objective. Research methodologies are an organized approach to accomplish the selected objectives. The research methodology comprises different techniques used during the experiment with surveys, tests, etc.

The chapter deals with the empirical findings and analyses in order to offer ample interpretation for a reliable conclusion to be drawn. In order to enhance and supplement the textual materials in this chapter, tables and models are frequently employed. Discussion is helpful in putting the study’s findings into proper perspective and connecting them to related research.

10.1 Introduction
Having explored the advanced analytical techniques that allow us to extract meaningful insights and build predictive models from meteorological data, we now arrive at a crucial stage in the scientific process: communication and understanding. The chapter, “Visualization of Meteorological Data,” focuses on the art and science of transforming complex numerical datasets into insightful visual representations. In a field as inherently spatial and temporal as meteorology, effective visualization is not just about making pretty pictures;it is a fundamental tool for exploration, analysis, and the clear conveyance  of information about atmospheric phenomena (Fig. 10.1).
Consider the sheer volume and multifaceted nature of meteorological data. We grapple with variables spanning three spatial dimensions (and often more when considering altitude), evolving dynamically over time, and encompassing a wide array of physical quantities – temperature, pressure, wind vectors, humidity, precipitation rates, radiation fluxes, and more. Raw numbers and statistical summaries, while essential for quantitative analysis, often fail to reveal the intricate spatial patterns, temporal evolutions, and interrelationships that characterize weather and climate. This is where visualization steps in,
acting as a bridge between the abstract world of numerical data and our intuitive human capacity for visual pattern recognition.

Throughout human history, people across the globe have sought to understand and predict the ever-changing skies. From the scorching deserts of North Africa to the lush rainforests of South America, and from the snow-capped Himalayas to the vast Australian outback, ancient cultures developed unique methods to forecast the weather. These traditional knowledge systems, often passed downthrough oral traditions and  storytelling, reflected the specific environmental contexts, mythological beliefs, and spiritual practices of each community. In ancient China, royal astronomers meticulously recorded weather patterns and planetary movements to guide agricultural planning and imperial decisionmakingIn Greece, philosophers like Aristotle and Theophrastus wrote extensively on weather signs and forecasting methods. In Africa, tribal communities observed animal migrations and plant behaviors to anticipate seasonal changes. Native American tribes used lunar cycles and star constellations to predict weather patterns, while ancient Indians studied the movements of planets and nakshatras (lunar mansions) to forecast monsoon rains.

The Enigmatic Monsoons - Welcome to a fascinating exploration of one of Earth’s most powerful and life-giving atmospheric phenomena: the Monsoons. More than just seasonal winds and rains, monsoons are intricate dance performances between land, sea, and atmosphere, shaping the climate, ecology, and very fabric of life across vast stretches of our planet, particularly the Indian subcontinent.
The word “monsoon” itself, derived from the Arabic word “mausim” meaning season, hints at the fundamental characteristic of these weather systems: a seasonal reversal of wind direction. This seemingly simple shift, however, unleashes dramatic transformations. Imagine landscapes parched and brown under the relentless summer sun suddenly bursting into vibrant green as lifesustaining rains arrive. Picture bustling cities and serene villages alike adapting their rhythms to the ebb and flow of the monsoon’s arrival and departure. This is the profound influence of the monsoons.
This chapter will delve deep into the heart of these dynamic systems. We will unravel the complex interplay of factors that lead to the birth, progression, and eventual retreat of monsoonal winds and the associated precipitation. We will journey through the scientific understanding of the mechanisms driving these large-scale atmospheric circulations, exploring the roles of differential heating of land and sea, the influence of global pressure belts, the impact of the majestic Himalayas, and the intricate dynamics of atmospheric currents like the Jet Stream.
Beyond the scientific mechanics, we will also explore the profound impact of monsoons on the regions they dominate. For billions of people, particularly in South and Southeast Asia, the monsoon is not just weather; it is life itself. It dictates agricultural cycles, influences cultural traditions, and shapes economic activities. A good monsoon can bring prosperity, while a weak or erratic one can lead to hardship and even disaster.

Introduction 
The preceding chapter elucidated the concepts of potential and achievable crop production, highlighting the significant gap that often exists between a crop‘s theoretical maximum yield and what is realized in the field. While genetic potential and optimal climatic conditions define the upper limits, the vast majority of agricultural systems globally operate under less-than-ideal circumstances. Among the most pervasive and impactful constraints on crop productivity are moisture (water) and nutrient limitations. These two factors, either individually or in complex interaction, are frequently the primary drivers of the yield gap, preventing crops from expressing their full genetic potential and significantly impacting farm profitability and regional food security. Water, as the universal solvent and a direct participant in photosynthesis and countless metabolic processes, is indispensable for plant life. However, its availability in agricultural systems is highly variable and often insufficient. From the rainfed fields dependent on increasingly erratic rainfall patterns to irrigated lands facing dwindling water resources, moisture stress – encompassing both drought and, paradoxically, waterlogging – poses an immense challenge. Drought alone accounts for a substantial portion of global crop losses, directly affecting plant physiological functions, growth, and ultimately, yield. Conversely, excessive moisture can lead to anaerobic soil conditions, nutrient leaching, and root damage, equally debilitating for crop performance. Parallel to moisture, the availability and judicious management of essential plant nutrients are foundational to productive agriculture. Plants require a suite of macro- and micronutrients for healthy growth, enzymatic activity, and the synthesis of biomass. Soils, over time and with continuous cropping, often become depleted of these vital elements, necessitating external application through fertilizers or the enhancement of natural nutrient cycling processes. However, nutrient management in the field is rarely perfect. Deficiencies of
