1. Introduction

The agriculture sector in Asia and the Pacific plays a vital role in the rural economy, making significant contributions to both GDP and employment. This sector serves as a cornerstone for food production, economic growth and poverty reduction in the region. Understanding the importance of farming in the region’s rural economy, as well as the need for viable farming systems particularly for smallholder farms, is essential for sustainable development.

Importance of Farming in the Rural Economy

Farming has a substantial impact on the rural economy of Asia and the Pacific. It serves as a primary source of income and livelihood for rural populations, contributing significantly to the region’s Gross Domestic Product (GDP). The agricultural sector encompasses a wide range of activities, including crop production, livestock farming, fisheries, and forestry, providing diverse opportunities for economic development.

According to the Food and Agriculture Organization (FAO), farming accounts for 29 percent of the region’s GDP (FAO, 2021). This demonstrates the significant economic value that agriculture brings to the region, making it a crucial sector for sustainable development. The revenue generated from agricultural activities supports not only farmers but also other stakeholders in the value chain, including agro-industries, distributors, and exporters.

Introduction Large cardamom is an important cash crop cultivated in Sikkim. It is also cultivated in Darjeeling district of West Bengal and some parts of North-eastern state like Arunachal Pradesh, Nagaland and Manipur. It is a low volume, high value non-perishable crop grown organicallyat different altitudes under the trees. The State produces about 4,970 tonnes annually from an area of 23,312 hectares (Spice board, 2021). Among the four districts of Sikkim, North and East Sikkim district contributes largest in terms of area and production of large cardamom (GoS, 2016). Off-late, climate change has become a major concern for the large cardamom growers as many researchers reported its contribution to the decline of its production. Sikkim, as Himalayan states, is endowed with varied agro-climate ranging from tropical in the South to alpine in the North. Shrestha et al. (2010) reported that warming in the Himalayas was between 0.15°C and 0.60°C per decade in the last three decades. Seetharam (2012) revealed that in Gangtok, there is a decreasing trend in maximum temperature while an increasing trend in minimum temperature. The study also depicted the decreasing trend of annual rainfall amount in the study area. In a recent study, Kumar et al. (2020) reported that the warming was more prominent in the last decades in Gangtok and Tadong station, better reflected in the minimum temperature with varied precipitation across the observed period from 1961 2017.

Introduction 
Sustainability refers to the ability to maintain a balanced and healthy equilibrium by addressing economic, social, and environmental demands over time. Sustainable development is a broad and evolving concept that aims to meet present needs without jeopardizing the ability of future generations to meet theirs. It seeks to balance short-term progress with long-term viability. The United Nations’ Sustainable Development Goals (SDGs), also known as the Global Goals, are a set of 17 goals and 169 targets that all UN Member States aim to achieve by 2030. SDG 3, which emphasizes ensuring healthy lives and promoting well-being for all at all ages, places a strong focus on health. Within SDG 3, reducing maternal mortality and decreasing neonatal and child mortality are key priorities, represented by Targets 3.1 and 3.2, respectively. The global goal for SDG 3.1 is to lower the maternal mortality ratio (MMR) to fewer than 70 per 100,000 live births by 2030. For individual countries, a supplementary target is set to reduce their national MMR to below 140 per 100,000 live births. A nation’s progress is fundamentally tied to the health and well-being of its mothers, which is a crucial factor in achieving equitable resource distribution, reducing poverty, and promoting sustainable development. Tragically, approximately 536,000 women die each year from maternal health complications, with 99% of these deaths occurring in developing nations. India, contributing about 25% of global maternal deaths, faces a critical challenge, with around 136,000 maternal deaths occurring annually. The country has set an ambitious goal to reduce its MMR to below 100 deaths per 100,000 live births. To address these issues and support sustainability, Reproductive and Child Health (RCH) indicators play an essential role in monitoring maternal and child health (MCH) outcomes. These indicators include measures such as immunization coverage, institutional delivery rates, home delivery rates, and antenatal care coverage. By tracking these metrics policymakers can assess the effectiveness of maternal health services and identify areas that require improvement. Utilizing RCH indicators to inform policies and programs contributes to better health outcomes for mothers and children and helps reduce mortality rates, which aligns with the objectives of SDG 3. Certain regions of India have made notable strides in improving MCH. For example, the northeastern state of Assam saw significant improvements in RCH indicators between 2010 and 2015. During this time, the rate of institutional deliveries increased substantially ensuring more women had access to safe childbirth services. The government has also strengthened maternal health care by implementing various MCH programs, including the RCH initiatives and other flagship schemes.

16.1 What is Sustainable Development?

Sustainable development (SD) is a pattern of resource use that aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come (sometimes taught as ELF-Environment, Local people, Future). The term was first  coined by the Brundtland Commission and defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” (UN, 1987; Smith and Rees, 1998)

The Global Environmental Issues

 
Expansion of the scale of human activity in recent years has put so much strain on the natural environment of this planet that in some cases nature can no longer recover. The nature’s ability though recovers damage or harmful effects in one part of the world do not stop in the very area and keeps going beyond national borders and become environmental problems on a global scale, but in a limited manner.

Introduction

Developing means of farming and agriculture is the reason humans can live in the world today. It is a necessary means of survival, without which there would be famines all over the world. For thousands of years, agriculture was a natural process that did not harm the land it was done on. In fact, farmers were able to pass down their land for many generations, and it would still be fertile as ever.

However, modern agricultural practices have started the process of agricultural pollution. This process causes the degradation of the ecosystem, land, and environment due to the modern-day by-products of agriculture.

Introduction

Painting is the practice of applying paint, pigment, colour or other medium to a solid surface (support base), Abdellatif MD, 2017. The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. Interior wall painting is a repetitive, exhausting and hazardous process. In almost all the developing countries, the increasing population stimulates the construction-related activities such as interior finishing and painting. Painting is classically done by humans and generally requires exhaustive physical efforts and involves exposure to dangerous chemicals.

Sustainability has recently become an important factor in the engineering world. Landscape architecture is a discipline that attempts to improve the way humans interact with the environment. That interaction can be improved in various ways such as water conservation, energy conservation, or urban planning. landscape architecture encompasses urban design, community and regional planning, interior and exterior garden design, parks and recreation, historic site and natural area preservation, energy and water conservation, landscape restoration and management, among others. The varied list is an example of the dynamic essence of landscaping and provides insight into the many areas which can be improved by implementing sustainable practices.

Sustainable development practices aim to protect the quality of life of future generations. This can only be done by understanding how the natural environment operates as well as how human interactions affect it. Sustainable Landscape Architecture focuses on enhancing the holistic knowledge of the surrounding landscapes, including the complex processes which naturally occur to maintain it. Employing this knowledge within the planning phases of development should result in the reduction of negative environmental impacts due to the same. The traditional consequences of land development can be eliminated or mitigated when developers are able to foresee the consequences of their work. Many times, replicating undeveloped conditions and/or native landscapes within the overall site design will prove very useful in achieving the goals of sustainability. All of the sustainable topics covered in this chapter involve the application of a technology that resulted from better understanding the natural environment.

Abstract

This chapter highlights the significance of irrigated desert agriculture as a prime cause of the settlement and welfare of nomads and the consequent reduction of conflicts over limited land resources. Um Jawaseer Desert Farm Project is located in Bayouda Desert, the Northern State about 200 km north of the capital Khartoum. The planning and management approaches of such irrigated projects were discussed with special emphasis on the participatory approach. In this respect the roles of the donor (NGO), traditional tribal institutions and the project beneficiaries were illustrated. The project beneficiaries were organized into the farmers, well and women committees. The environmental and socioeconomic impacts of the project were evaluated. The project maintained food security, improved nutritional status, hygiene, housing environment and assisted in the provision of primary education and basic health facilities. Cost/benefit analysis showed the high profitability of the project. Other positive impacts include conservation of the fragile environment and biodiversity and improvement of animal productivity. Consequently, the area which witnessed an out-migration, during the seventies and the eighties, due to drought and desertification is now experiencing incoming migration.

However, adaptation to the sedentary mode of life was a real challenge. The most striking benefits of the project was that of women training for the, involvement in the decision-making process and empowerment, since 20% of the land is allocated for women. In addition to that, problems like build up of salinity, sand encroachment, low organic matter content and increased susceptibility to some water-related diseases due to irrigation were tackled successfully.

The development of green nanocomposites requires more than replacing conventional materials with renewable alternatives; it also requires responsible sourcing, efficient resource utilization, and consideration of the complete material life cycle. This chapter examines green and eco-friendly nanocomposites from the perspective of sustainable material selection and circular economy principles. It discusses strategies for obtaining renewable raw materials, reducing environmental impacts, improving resource efficiency, and designing materials for reuse, recycling, and recovery. Applications of green nanocomposites are also considered in relation to sustainability objectives. By connecting material development with circular economy strategies, the chapter provides a framework for developing nanocomposites that combine functional performance with reduced environmental burden.

Abstract
 
India shares 16% of the world population, while its land is only 2% of the total geographical area of the world. Naturally, the pressure on the land is often beyond its carrying capacity. Therefore, the productive lands, especially the farmlands in the India are in the constant process of various degrees of degradation and are fast turning into wastelands. At present, approximately 68.35 million hectare area of the land is lying as wastelands in India. Out of these lands, approximately 50% lands are such non-forest lands, which can be made fertile again if treated properly. It was unprotected non-forestlands, which suffered the maximum degradation mainly due to the tremendous biotic pressure on it. In the last 50 years it is India's lush green village forests and woodlots have been deforested to the maximum. 

“Sustainable Water Resources Management Strategies” embarks on a comprehensive exploration of the paramount challenges and essential solutions for safeguarding our planet’s most precious resource: water. This recognizes that water is not merely a commodity but the very lifeblood of ecosystems, a cornerstone of human health, a critical input for food production, and an indispensable element for industrial progress and societal well-being. Building upon a fundamental understanding of the intricate hydrological cycle, the distribution of global water resources, and the escalating anthropogenic pressures they face, we now turn our attention to the proactive and forwardthinking approaches that define sustainable water resources management. • In an era marked by increasing environmental consciousness and the stark realities of climate change, the traditional paradigms of water management are proving inadequate. Growing populations, rapid urbanization, and the expansion of industrial activities place unprecedented demands on both the quantity and quality of available water. Furthermore, the erratic and often extreme

Introduction 
Sorghum bicolor L. Moench, commonly known as sorghum, has emerged as a significant and promising candidate for both sugar and lignocellulosic biofuel production. Cultivated sorghum varieties exhibit a wide range of phenotypic and morphological characteristics, and based on their intended use, they have been categorized into four distinct groups: grain, forage, energy, and sweet sorghum. Grain sorghum varieties typically stand between three to six feet in height, featuring large ear heads. Their primary role is to serve as a source of food for humans or livestock feed. These varieties play a crucial role in providing sustenance and nutrition to both people and animals. Sweet sorghum, also known as sweet stalk sorghum, represents a unique group of genotypes that accumulate soluble sugars within their stalks. These varieties can grow impressively tall, reaching up to twenty feet, and produce significantly higher biomass yields compared to grain sorghum (Murray et al., 2009). Sweet sorghum’s stems are characterized by their thickness and fleshiness, although they do tend to have relatively lower seed yields. Despite this, sweet sorghum offers substantial advantages in terms of bioethanol production due to the high sucrose content present in its stalks (Srinivasa Rao et al. 2009). It has garnered recognition as an ideal candidate for bioenergy crop cultivation in tropical and temperate regions around the world, particularly in the southern United States. When compared to other bioenergy crops such as corn, wheat, sugarcane, sugar beet, cassava, and sweet potatoes, sweet sorghum presents several noteworthy benefits (Disasa et al., 2016). It is notably drought-tolerant and requires significantly less water than many other crops, such as one-third of the water needed for sugarcane and half of that required for corn. Furthermore, it exhibits tolerance to salinity, enabling its cultivation in marginal regions that are not traditionally suitable for crop production. Additionally, sweet sorghum boasts lower greenhouse gas emissions on a life-cycle basis, contributing to a more sustainable and environmentally friendly biofuel production process. The applications of sweet sorghum are diverse, with its stalks being used for various purposes. In Brazil and India, the stalk is chewed fresh or processed for the production of food-grade syrup and alcohol. Its high sucrose content makes it an excellent candidate for bioethanol production, with the potential to yield up to 8,000 liters per hectare, surpassing the ethanol yield of corn by approximately twofold and outperforming

Abstract

Tsunami (2004), that struck the Tamil Nadu coast has left deep marks in the minds of the affected society. The interview conducted in the coastal villages of the tsunami affected Nagapattinam has brought out many salient societal issues like, loss of leadership, widow hood, debt grip, psychological depression etc, which warrant deeper look to bring them out from the syndrome.

INTRODUCTION

The damages caused by tsunami (2004) along the coastlines of most of the South Asian countries are indelible not only from the minds of the coastal population but also from the heart of the entire humanity. The worst affected in the disaster are the fishing community. Many of their mechanized and un-mechanized boats and catamarans were converted to useless debris and garbages by the heartless tsunami. When their settlements themselves were swallowed even with out chewing, nothing to talk about their fishing nets which were just blown off by the ferocious tsunami. In addition, the infrastructure facilities like roads, communication systems, water and power supply were also incalculably damaged. Next to fishermen community, the affected souls were the farmers whose cultivable lands were turned into marine wet lands with swimming and tossing fishes. The Indian subcontinent was facing such onslaughts of various natural disasters periodically but our morale always stood by our side prohibiting us declaring them as national calamities for getting international aids. Specifically in this case, the central and state governments, NGOs and Voluntary Organizations have risen phenomenally to help the affected who were in need. Despite best efforts taken to provide relief and rehabilitation to the affected people, the tsunami has seedled some societal issues / syndrome, which may take long years to settle; it may not settle too. The paper discusses some of such issues gulled out through the interview conducted amongst various cross sections of the affected community.

The communication system provides the forecaster with a large mass of figures; the next step is to put them into a suitable form for study. This is done by plotting the observations on a large outline map which in popular term is called a “Weather map” technically a “Synoptic chart” simplified synoptic charts appear in some newspaper.

A chart or map on which meteorological data presented and analysed is called a synoptic chart. Synoptic means having the same view point. The representation of the meteorological data in synoptic chart are atmospheric wind, temperature, pressure, cloud, precipitation, dew point etc., over a long area at a given local standard times.

Introduction 
A system approach to understand the soil-plant-water continuum fundamentally shifts our perspective from viewing these elements in isolation to recognizing them as an intricately woven, dynamic whole. It’s about appreciating that every change in one part of this natural tapestry—be it the soil, the plant, or the water itself—reverberates through the others, creating a cascade of interconnected effects. This holistic lens allows us to dissect the continuous exchange of water and energy, unraveling the complex feedback loops and emergent behaviors that characterize this vital agricultural system. Instead of merely tracking individual inputs and outputs, a systems view compels us to comprehend how these components influence each other over time, leading to a far more nuanced understanding of their collective behavior. At the heart of this continuum lie three primary, yet inseparable, components: the soil, the plant, and the water itself, all profoundly influenced by the atmosphere. The soil acts as both a foundational anchor and a dynamic reservoir. Its very composition—the proportion of sand, silt, and clay, its structure, and its organic matter content—dictates how readily water infiltrates, how much it can hold against the pull of gravity, and how quickly it can release water to plant roots. Processes like infiltration, percolation, and capillary rise describe water’s journey within the soil matrix, while evaporation from the soil surface represents a significant loss pathway. Crucially, the soil also serves as the medium for nutrient availability, with water acting as the solvent that transports these vital elements to the roots. The plant, in turn, is the primary biological conduit for water’s journey from the soil back to the atmosphere. It actively absorbs water through its roots, moving it upward through the xylem to the leaves, where it is transpired through tiny pores called stomata. This transpiration process is not merely a loss; it’s the driving force behind the plant’s physiological engine, facilitating

Introduction

Training is the crucial and expensive component of HRD, intended to improve the efficiency and effectiveness of performance of the members of organization through planned learning efforts, transfer of such learning at work place and in turn improvement of the organizational performance. Given such objectives, most of the training programmes fail to inculcate the transfer component in trainees (Subedi 2004). Hence, there is an increasing concern over training transfer at work place and the resultant improved organizational performance in terms of productivity, efficiency, effectiveness and turn over etc (Howard 1995, Huselid 1995, Martocchio and Baldwin 1997 and Salas et al.. 2000, Thayer1997).

ABSTRACT

The exponential growth of population and rapid industrialization, urbanization, deforestation and improper landuse practices have led to depletion and pollution of surface and ground water resources in Tamilnadu, India. In addition, a recurrent monsoonal failure further aggravates the problem of water even for drinking water. Water plays vital role in our day to day life and other developmental activities in the area. Thus, the availability of surface and sub surface water potential governs the processes of planning and development. The surface water resources are inadequate to fill the water demand and productivity through ground water is quite high as compared to surface water. Keeping this in view, the present study is aimed to identify the potential location of potable groundwater exploration in hard rock terrain. Thematic information on geomorphic landforms, Landuse/landcover and lineament details are extracted from remotely sensed data. Geology, Soil class, Drainage network and Slope map of the terrain were prepared using existing maps and collateral data by conventional method. GIS based model was developed and appropriate rank and weightage had been assigned to all categories based on local conditions/variations in each layer according to relative contribution towards the desired output. Since the present study built with logical condition and reasoning rule based approach for groundwater targeting, it has been successfully used and clearly demonstrated the capability of Remote Sensing and GIS techniques in identification of potable ground water potential zones.

Tea (Camellia sinensis) is one of the most important beverage crops in the World and the second most commonly drank liquid on earth after water. It has numerous medicinal benefits mainly due to its antibacterial and
antioxidant properties. The major tea growing regions of the world are South-East Asia (India and Sri Lanka), Eastern and South Africa consisting of Kenya, Malawi, Tanzania, Uganda and Mozambique. All these countries are producers of black tea. China and Japan are the major producers of green tea. These countries experience cool, tropical humid climate where this crop is being cultivated. However, at present, the crop is also being cultivated in wide range of climates from Mediterranean to warm, humid tropics to include countries such as Russia and Georgia in the northern latitudes and Argentina and Australia in the southern latitudes (Plate 8. 1). The region to which the crop is grown is closely linked with the climate. The crop is grown across wide altitudes up to 2200 m a.m.s.l. Sri Lanka, Kenya, China and Vietnam are the major competitors to India in tea exporting field. China is the major producer of green tea while Sri Lanka and Indonesia are producing mainly orthodox varieties of tea. Tea industry in India occupies an important place in the national economy since last 172 years. It is an essential item of domestic consumption. Tea is also considered as the cheapest beverage amongst the beverages available in India.
