Several nano-scale devices have emerged that are capable of analysing plant diseases, nutrient deficiencies and any other ailments that may affect food security in agro-ecosystems. It has been envisioned that smart delivery systems can be developed and utilised for better management of agricultural ecosystems. These systems could exhibit beneficial, multi-functional characteristics, which could be used to assess and also control habitat-imposed stresses to crops. Nanoparticle-mediated smart delivery systems can control the delivery of nutrients or bioactive and/or pesticide molecules in plants. It has been suggested that nano-particles in plants might help determine their nutrient status and could also be used as cures in agro-ecosystems. Further, to enhance soil and crop productivity, nanotechnology has been used to create and deliver nano fertilizers, which can be defined as nano-particles that directly help supply nutrients for plant growth and soil productivity. Nano-particles can be absorbed onto clay networks, leading to improved soil health and more efficient nutrient use by crops. Additionally, fertilizer particles can be coated with nano-particles that facilitate slow and steady release of nutrients, reducing loss of nutrients and enhancing their efficiency in agri-crops. Although the use of nanotechnology in agro-ecosystems is still in its early stages and needs to be developed further, nano-particle-mediated delivery systems are promising solutions for the successful management of agri-ecosystems. In this context, the book offers insights into nanotechnology in agro-ecosystems with reference to biogenic nanoparticles. It highlights the: * occurrence and diversity of Biogenic Nanoparticles * mechanistic approach involved in the synthesis of biogenic nanoparticles * synthesis of nanoparticles using photo-activation, and their fate in the soil ecosystem * potential applications of nanoparticles in agricultural systems * application and biogenic synthesis of gold nanoparticles and their characterization * impact of biogenic nanoparticles on biotic stress to plants * mechanistic approaches involved in the antimicrobial effects and cytotoxicity of biogenic nanoparticles * role of biogenic nanoparticles in plant diseases management * relevance of biological synthesized nanoparticles in the longevity of agricultural crops * design and synthesis of nano-biosensors for monitoring pollutants in water, soil and plant systems * applications of nanotechnology in agriculture with special refer to soil, water and plant sciences A useful resource for postgraduate and research students in the field of plant and agricultural sciences, it is also of interest to researchers working in nano and biotechnology.

Urbanization, industrialization, and unethical agricultural practices have considerably negative effects on the environment, flora, fauna, and the health and safety of humanity. Over the last decade, green chemistry research has focused on discovering and utilizing safer, more environmentally friendly processes to synthesize products like organic compounds, inorganic compounds, medicines, proteins, enzymes, and food supplements. These green processes exist in other interdisciplinary fields of science and technology, like chemistry, physics, biology, and biotechnology, Still the majority of processes in these fields use and generate toxic raw materials, resulting in techniques and byproducts which damage the environment. Green chemistry principles, alternatively, consider preventing waste generation altogether, the atom economy, using less toxic raw materials and solvents, and opting for reducing environmentally damaging byproducts through energy efficiency. Green chemistry is, therefore, the most important field relating to the sustainable development of resources without harmfully impacting the environment. This book provides in-depth research on the use of green chemistry principles for a number of applications.

In addition, the book covers the use of microbial biofilm- and algae-based bioelectrochemical systems for bioremediation and co-generation of valuable chemicals. A thorough review of the performance of this technology and its possible industrial applications is presented. The book is designed for a broad audience, including undergraduates, postgraduates, energy researchers/scientists, policymakers, and anyone else interested in the latest developments in this field.

This book provides a blueprint for the allocation of public expenditures "in" and "for" agriculture at the dis-aggregated state level and suggests a reorientation in favour of disadvantaged regions where the marginal returns on additional investments would be higher. It provides insights into the inter-linkages between public expenditures, private investment, rural poverty, and agriculture productivity from a regional perspective to reflect upon spatial differences in the welfare effects of various investments, subsidies, and policies. The book focuses on agricultural growth and rural poverty reduction through public and private investments, non-farm employment, and other pathways to the formulation of appropriate policies at the dis-aggregated state level. It presents new evidence based on advanced econometric tools for analysing and understanding the relationship between public and private investments in agriculture and input subsidies (fertilizer, power, irrigation, and credit) together with their impacts at the dis-aggregated state level. The book also deliberates on an income based direct support system for farmers as an alternative to the existing input price subsidy regime. Accordingly, the book offers valuable insights not only for researchers working on poverty alleviation, rural economy, and agricultural growth, but also for policymakers.

Food systems involve a range of activities concerning food production, processing, distribution, marketing and trade, preparation, consumption and disposal. They encompass the path of food from the farm to the dinner table, meeting the food and nutritional needs of a nation. When such systems do so without sacrificing the needs of future generations, they are referred to as "Sustainable Food Systems." The natural and physical environment, infrastructure, institutions, society and culture, and policies and regulations within which they operate, as well as the technologies they adopt, shape these systems' outcomes. Making food systems more sustainable is a key priority for all nations, and Sri Lanka is no exception. Food systems deliver optimal performance when the policy and regulatory environment is conducive, institutions are supportive, and a combination of agricultural research investments and an efficient extension system generates the technologies and scientific evidence required for sound policymaking and agenda setting. Further, agricultural research can generate essential findings, technologies and policies for sustainable agricultural development - across disciplines, sectors and stakeholder groups. This book shares valuable insights into research conducted in the broad food and agriculture sectors in Sri Lanka. It also discusses the status quo in related disciplines, and outlines future research directions. Accordingly, it offers a valuable source of reference material for researchers, students, and stakeholders in the food and agriculture sectors, while also highlighting the types of support that policymakers and other decision-makers can provide.

This book provides different facets of India's agro and food processing industry in both organised and unorganised segments. It brings forth the topical issues having potential to accelerate the pace of growth in its employment, investment and productivity and strive for improving the global competitiveness. Using advanced quantitative techniques, it brings new evidences on inter-sectoral (agriculture-industry-services) employment and production linkages, contractual arrangements through Farmer Producer Companies, and subcontracting in the processed food sector. It also throws light on India's comparative advantage in export of primary and processed food products. With rising per capita income, urbanisation, and changing food habits of people, India is increasingly striving to improve productivity and competitiveness in agriculture and manufacturing. A concerted policy focus to accelerate private investment in food processing, largely viewed as a sunrise industry, is expected to contribute to large scale job creation and external trade not only in the manufacturing but also in the agricultural sector. Keeping this in mind, considerable insights are featured in the book at the industry and firm levels due to a significant bearing of technological, tariffs and non-tariff barriers and labour regulations on their trade intensity, employment and efficiency. Containing perspectives from the top agriculture and industry economists in the country, the book will be very useful to researchers, academicians, trade analysts and policy makers.

An increasing population has put tremendous pressure on agricultural productivity to fulfill the demands of human consumption. Numerous agricultural activities and techniques have been developed to raise annual crop production globally. While agriculture has succeeded in enhancing the yearly crop productivity, this achievement is at the cost of environmental degradation by applying synthetic persistent substances, such as industrial fertilizers, pesticides, herbicides, etc. Chemical fertilizers are nearly as destructive as they are productive, causing monocultures and consequences associated with elimination of diversity, nutrient pollution as evidenced by algae blooms, eutrophication, water quality issues, lower oxygen levels and dangers to fish stocks. Therefore, the scientific approach to maintain sustainable fertility in soil and plants is to switch over to biofertilisers.Biofertilisers are compounds of organic matter that are applied to crops for growth and health. Their constituent micro-organisms interact in an ecofriendly manner with the soil, root and seeds of plants, promoting the growth of micro-flora that enhances soil fertility. They are known to play a number of vital roles in soil fertility, crop productivity and production in agriculture. Application of biofertilisers results in increased mineral and water uptake, root development, vegetative growth and nitrogen fixation. They liberate growth promoting substances and vitamins and help to maintain soil fertility. They act as antagonists and play a pivotal role in neutralising the soil borne plant pathogens, thereby assisting in the bio-control of diseases. Application of biofertilisers in lieu of synthetic fertilizers could be the promising technique to raise agricultural productivity without degrading the environmental quality. The present book focuses on the latest research approaches and updates from the microbiota ecosystem and their applications in agriculture industry. It also highlights the great potential and possible future of action of microbiota in the development of sustainable agricultural systems.

In Sub-Saharan Africa, the rapidly evolving COVID-19, increasing population growth, and exponential expansion in demand for agricultural commodities are putting pressure on available resources, thereby posing immense challenges to the region's capacity to achieve nutritional security related to United Nations Sustainable Development Goals (SDGs). Although Sub-Saharan Africa boasts vast, fertile and uncultivated arable lands, its capacity to contribute to feeding its current and future population is being seriously undermined by factors such as poor adoption and utilization of innovations and digital tools, climate change impact, environmental degradation, weak political will, limited interest in farming, lack of government support, and more. In spite of these constraints, sustainable agriculture, food security and nutrition security in Sub-Saharan Africa can be achieved by adopting a multi-pronged approach, which includes improved agricultural mechanization, adoption of high yielding crop varieties, use of information technology, public investments in improved technologies, and rural infrastructure funding. This edited volume provides innovative policy tools for enhancing Sub-Saharan Africa's capacity to achieve sustainable agriculture, food security and nutrition security in the digital age and in the face of climate variability.
