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.

After the Green Revolution, it is now time for an Ever-Green Revolution based on Eco Agriculture or Agroecology. In 2018, the FAO described Agroecology/Eco Agriculture as a means to transform food and agriculture systems by addressing root causes and emphasizing the improvement of efficiency in resource use, conserving, protecting and improving livelihoods, promoting equality and well-being and enhancing the resilience of people, communities and ecosystems. A timely transition to a sustainable eco-agriculture approach is essential to protect food security, the well-being of people and farmers prosperity. Eco Agriculture is a broad term that can inclusively refer to agroecology, regenerative, organic, natural, jaivik, etc, and is increasingly being recognized as the way to help save the planet. While discussing this with Prof Swaminathan and the ICFA team, the idea of a Working Group emerged. When I was requested to form the Eco Agri Working Group through ICFA, I consulted with different sectors and tried to determine the “why” and “how” of the impending Eco Agri Revolution.
WHY
The past sixty years led to Green Revolution and alongwith that ‘success’ several adverse impacts and the changing global situation as noted in Table – 1 are the reasons for the need for an Evergreen Revolution based on Eco Agriculture

Natural resources are naturally occurring resources which can be exploited for economic gain. They include raw materials such as fuels, minerals and metals, soil, water, air, sunlight, land, biomass and ecosystems. Natural resources also include living (biotic) and non-living (abiotic) materials. Natural resources are gifts of nature for the humankind.

Introduction to sustainable disease management

Plants and pathogens are involved in ongoing interactions over millennia that have been modified by coevolutionary processes to limit the spatial extent and temporal duration of disease epidemics (Zhan et al. 2015). These interactions are disrupted by modern agricultural practices, such as intensified monoculture using high yielding varieties. Agricultural intensification and monoculture coupled with globalization disrupt the coevolutionary dynamics of plant-pathogen interactions which escalating the evolutionary rate of pathogens and increasing the risk of plant disease epidemics. These activities, when supplemented with high resource inputs, create unique conditions which is conducive to widespread plant disease epidemics and rapid evolution of pathogen. Disease management requires a significant shift to include ecoevolutionary principles in the design of adaptive disease management strategy for minimizing the evolutionary potential of plant pathogens by reducing their genetic variation, stabilizing their evolutionary dynamics, and preventing dissemination of pathogen variants carrying new infectivity or resistance to pesticides (Zhan et al. 2014). As environmental and ecological issues continue to impact on agriculture, all the crop-specific and regional-specific, Good Agricultural Practices (GAP) to be developed for crop production, must be economically feasible, ecologically sound, environmentally safe and socially acceptable. Numerous non-chemical methods for management of crop diseases such as pathogen-free seeds, disease resistance, crop rotation, plant extracts, organic amendments and biological control agents are considered less harmful than chemical pesticides and therefore, offer great potential for application in modern agriculture (Marshal et al. 2008). No single method can provide satisfactory management of crop diseases. Integration of all the effective and eco-friendly measures in accordance with the dynamics of the agro-ecosystem management would be the best strategy for efficient plant disease management.

The stability of agriculture all over the planet and the accessibility of food are both signi?cantly affected by Climate change. Thus, it is desperately important to create and execute Climate -resilient farming techniques and advancements that can help farmers in acclimating to the e?ects of Climate change. It should be finished right away. It examines the issues welcomed on by Climate change, fundamentals of sustainable agriculture, and the instruments and strategies that can be utilized to expand farming’s protection from Climate change. This part essentially talks about Climate -friendly creature farming, viable water system frameworks, weather conditions checking and determining, crops that can endure dry spell and flooding, coordinated bug control, and sustainable power sources. To make sustainable more Climate change-safe, this part additionally talks about the need to empower feasible land-use rehearses and to make innovative work ventures. By using these innovation and methods, farmer might add to the maintainability and versatility of the food framework.
As a result of increasing temperatures and diminishing precipitation because of Climate change, farming is enduring enormously all over the planet. This is especially evident in India, where the greater part of the populace is utilized in farming. The effect of Climate change is perhaps of the main issue the world is at present encountering. The impacts of Climate change are felt and found in each part of society, including farming. Utilizing harmless to the ecosystem circular agriculture is critical now like never before as the total populace develops. One of these strategies is farming that is circular agriculture (CRA). Its central goal is to adjust cultivating practices to an evolving environment. Consistently, new people enter the earth. To take care of the growing populace, the land is feeling the squeeze to give more food, fiber, and fuel. Consistently, new people are brought into the world. Thus, the land is feeling the squeeze to create more food, fiber, and fuel to take care of the populace that is extending. As well as expanding crop efficiency, more Climate tough agricultural methods would likewise work on the soundness of the dirt and the biological system

Abstract

Indigenous chickens play vital role in sustainable rural development by providing livelihood and nutritional security to the rural and tribal people. However, indigenous chickens in the country increasingly face the threat of their replacement or erosion in their genetic diversity due to introduction of exotic or improved chickens to enhance productivity of backyard poultry production. Therefore, it becomes imperative to improve the growth and productivity of indigenous chickens in order to make the rearing of indigenous chickens economically attractive proposition. Aseel is one of the important indigenous breeds of chicken that is being conserved and improved for growth and egg production at Directorate of Poultry Research (DPR), Hyderabad. The averageegg production of improved Aseel chickens recorded in a laying cycle of 72 weeks of age was 150.3±5.63with an average egg weight of 48.66 ±0.34g. The average body weights of male and female birds recorded at 72 weeks of age were 3156 ± 27.4 and 2133±36.1 g, respectively while corresponding shank lengths were 135.23±0.7 and 104.9±0.4 mm. Another indigenous chicken germplasm, Ghagus-ecotype was collected from border area of Karnataka and Andhra Pradesh at Kolar district and is being characterized and conserved at DPR. The comparative growth performance of these indigenous chickens was also studied under similar management conditions. It was observed that the growth and egg production of improved Aseel breed was significantly higher than the Ghagus-ecotype chickens. The improved Aseel breed with its better growth and production performance appears to be a promising indigenous chicken for sustainable rural poultry production.

SUMMARY

Sustainable agricultural development can only be possible, when all agricultural inputs used judicially. Soil management practices, like nutrient management, time schedule of fertilizer application, irrigation management etc. are should be manage in such away that resulted in best remuneration and sustain overall soil health. More over that, soil physical properties like, tilth, aeration and drainage are also play important role in soil productivity, so tillage operation should be carry out at proper  level of soil moisture condition to maintain good soil tilth which result in better soil environment for high crop yield. The most important factor in sustainable soil management for agricultural development is nutrient management and it's only possible through integration. So nutrient management through integrated approaches, like use of chemical fertilizer is decreases by integrating with organic manures, biofertilizer, green manure, neem cake, caster cake etc which resulted in sustainable crop production and good soil health on long-term basis.

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.

The Sustainable Sugarcane Initiative (SSI) aims at providing practical options to the farmers in improving the productivity of land, water and labour, all at the same time. SSI is also expected to reduce the overall pressure on water resources and contribute to the recovery of ecosystems. Sustainable Sugarcane Initiative is an innovative method of sugarcane production using less seeds, less water and optimum utilization of fertilizers and land to achieve more yields.

Abstract
Agriculture is still main grindstone for the population in India. Even though the insistence for the agriculture produces expanding constantly due to the rising in the population, Due to this, Indian farmers are not getting assisted in this context. The rate of drop out from agriculture is enhancing from generation to generation. One of the main apprehensions is agriculture which is not becoming effective for the farmers. Thus to preserve their lives many farmers are quitting agriculture and migrating to urban areas ultimately. This will leads to deterioration in supply of food grains to integrated nation. At the same time, the capacity of land is declining due to reduction in the fertility of the land over years. The input cost for agriculture is also increasing steadily. The situation arrived where we have to enhance the income levels of the farmers along with attaining the sustainability in the agricultural practices. Therefore, a shift from agriculture to agribusiness is an important pathway to revitalize Indian agriculture and to make more attractive and profitable venture.

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

Water is a vital component of agricultural production. It is essential to maximise both yield and quality. Water has to be applied in the right amounts at the right time in order to achieve the right crop result. At the same time, the application of water should avoid waste of a valuable resource and be in sympathy with the environment as a whole. Understanding, measuring and assessing how water f lows around the farm, and recognising how farming practices affect f lows, will help farmers to manage water efficiently and reduce pollution risks. Land management and advanced technologies can help maximise the “crop per drop” that farmers produce worldwide. Water used in irrigation accounts for 90% of agricultural water demand. Improving irrigation systems is therefore crucial to making contributions to water savings in agriculture. In any agricultural production system the promotion of good agricultural practices and product stewardship is fundamental for sustainable agriculture. Industry is part of various multi stakeholder partnership initiatives that support efforts to protect water quality. These include reducing soil erosion, avoiding pesticide run-off and maintaining wildlife habitats as part of a holistic farm or land management approach.

Introduction

Though the potential benefits generated by the drip irrigation method are apparent, the adoption of drip irrigation is yet to be widely promoted across different regions and states in India. Several factors such as huge initial investment, small size of holding, lack of technical support, nature of cropping pattern, access to water and socio-economic conditions of farmers etc. (Namara et al, 2005, Suresh Kumar, 2012) are constraining adoption of drip irrigation. In some cases, even after the adoption of drip irrigation, the farmers, particularly, the small farmers have often discontinued use of drip irrigation for several reasons such as due to lack of maintenance, irrelevant cultural background, and unreliable water supply (Kulecho and Weatherhead, 2005).

Background and Technology Intervention

Owing to the subsequent monsoon failures and unavailability of water for irrigation, Tamil Nadu farmers have switched over to drip irrigation which is not only saving huge quantity of water for them, but also preventing irrigation run off and providing deep water percolation. In Tamil Nadu, usage of drip irrigation is prevalent among vegetable and fruit growers and organic farmers.

To relieve the plants from stress or strain of water logging and water scarcity, Tamil Nadu Horticulture Development Agency has played a key role by rightly intervening the farmers through drip irrigation technology and thereby improving water use efficiency.

Introduction

Weeds are the most costly category of agricultural pests, causing more yield losses and added labor costs than either insect pests or crop disease. Weeds are a constant fact of life in annual row crops, vegetables, and other horticultural crops. In India, the manual method of weed control is quite popular and effective. The usage of herbicides in India and elsewhere in the world is increasing due to possible benefits to farmers. At the same time, the continuous use of herbicides of the same weed shift, herbicide resistance in weeds and environmental pollutions. Application of herbicides also kills species of bacteria, fungi and protozoa thereby upsetting the balance of pathogens and beneficial micro organisms. The complexity of these situations has resulted in a need to develop a holistic sustainable eco-friendly weed management programme throughout the farming period (Gnanavel and Natarajan, 2014). Sustainable development of agriculture is concerned about the conservation of land, water, plant and animal genetic resources, is environmentally non-degrading, technically appropriate, economically viable and socially acceptable. Sustainable weed management is the use of weed control methods that are socially acceptable, environmentally benign and cost-effective.

There appears a general consensus that agriculture sector in India requires to be revitalized to enable it to respond effectively to the multitude of challenges that it now faces, and include assuring food security and environmental sustainability against the background of declining natural resources, changing climate and needs to become increasingly competitive.

Sustainable agricultural practices cover a whole range of improving sustainability: raising soil fertility, improving water storage capacity, increasing water quality, diversification, raising people’s capability to cope with risks and withstand natural calamities, reducing energy consumption, minimizing risk, and so on.

It is impossible to achieve sustainable development without applying sustainable agriculture on a large scale. The relationship between agricultural production and eradication of extreme poverty and hunger is very strong: agriculture is the very basis for food security. Together with fisheries, it provides practically all of the world’s food.

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

Nitrogen is the most important plant nutrient for increasing crop productivity. A few prokaryotic microorganisms are able to fix N2 directly mediated by enzyme nitrogenase. Annual biological nitrogen fixation (Table 96) is estimated to be around 175 million metric tonnes per year of which about 139 million tonnes (79%) are accounted for by terrestrial fixation (Burns and Hardy 1975).

The nitrogen fixers involved are metabolically diverse but the process is similar and depends upon (1) nitrogenase (Nase) enzyme complex (ii) a high energy requirement (ATP) (iii) anaerobic conditions for nitrogenase activity (iv) source of strong reductant.

The symbiotic process is known to be one of the important contributors to the nitrogen cycle both from agricultural and ecological points of view. The soil bacteria of the genus Rhizobium colonizes and forms nodules on the root of leguminous plants such as clover, lucerne (alfalfa), pea, chickpea, pigeonpea, beans, groundnut, Vigna species etc.

The nitrogen uptake in legumes by some unknown process was demonstrated through agronomic experiments by J.B. Boussigault in 1838 which was opposed by Liebig and others. However, Hellriegel and Wilfarth’s experiments (1886-88) clearly showed that the growth of non-leguminous plants, barley, oats etc. was directly proportional to the amount of nitrate supplied while in case of leguminous no such relationship existed and growth of the leguminous plants picked up in some cases after the seedling stage. Beijerinck (1888) isolated the bacterium from the root nodules in pure culture which lead to study their morphological characteristics and physiology.
