Food Security in Nutrient-Stressed Environments: Exploiting Plants’ Genetic Capabilities


Book Description

Ultimate success in exploiting the genetic capabilities of plants to grow in nutrient-stressed environments of the semi-arid tropics (SAT) requires a holistic view of food systems to ensure that genetic selections for improved yields on nutrient-poor soils will actually be adopted by farmers. This book sets out to address the important issue of how physiological mechanisms of nutrient uptake can best be combined with genetic options to improve the adaptation of crops to low-nutrient availability, thereby enhancing productivity of nutrient poor soils in the semi-arid tropics. The book examines (i) the sustainability of breeding for low-nutrient environments from the viewpoint of three interrelated disciplines; physiology, breeding, and socio-economics, (ii) candidate mechanisms and physiological traits to enhance uptake and utilization efficiencies, (iii) genetic approaches for manipulation of crop plants to enhance root exudation and access nutrients in the rhizosphere, and (iv) field practices and farmers' preferences for crop varieties grown in low-nutrient environments. Finally, the role of modelling in improving nutrient efficiency in cropping systems, recommendations for future research needs and strategies were highlighted. Attended by 50 international participants, this book is the outcome of the workshop held at ICRISAT-India during 27-30 September 1999 to mark the culmination of the Government of Japan/ICRISAT Project.










Plant Nutrition and Food Security in the Era of Climate Change


Book Description

Plant nutrients are the vital elements essential for plant growth and survival, with key roles in adapting to challenging environments. Each nutrient, whether required in relatively large (macronutrients) or minute concentrations (micronutrients) plays a unique role in plant life cycle. Both the insufficient and surplus concentrations of these nutrients may render negative impacts on plant growth and development and therefore their homeostasis is considered critical for optimal plant growth and yield. Plant Nutrition and Food Security in the Era of Climate Change comprehensively reviews all critical plant nutrients. Chapters include topics such as: biological roles, uptake and transport of vital nutrients in plants; an in-depth review of the roles of potassium, calcium, magnesium and trace element; molecular breeding approaches for enhanced plant nutrients; and exploring the rhizosphere microbiome for enhance nutrient availability. Written by leading experts in the field of plant biology, this is an essential read for researchers and scientists interested in plant science, agronomy, food security and environmental science. A comprehensive review of all the important plant nutrients Discusses plant homeostasis under natural and changing environments Introduces novel approaches and state-of-the-art tool for enhancing the levels of targeted nutrients within plant tissues




Food Security and Climate Change


Book Description

This book looks at the current state of food security and climate change, discusses the issues that are affecting them, and the actions required to ensure there will be enough food for the future. By casting a much wider net than most previously published books—to include select novel approaches, techniques, genes from crop diverse genetic resources or relatives—it shows how agriculture may still be able to triumph over the very real threat of climate change. Food Security and Climate Change integrates various challenges posed by changing climate, increasing population, sustainability in crop productivity, demand for food grains to sustain food security, and the anticipated future need for nutritious quality foods. It looks at individual factors resulting from climate change, including rising carbon emission levels, increasing temperature, disruptions in rainfall patterns, drought, and their combined impact on planting environments, crop adaptation, production, and management. The role of plant genetic resources, breeding technologies of crops, biotechnologies, and integrated farm management and agronomic good practices are included, and demonstrate the significance of food grain production in achieving food security during climate change. Food Security and Climate Change is an excellent book for researchers, scientists, students, and policy makers involved in agricultural science and technology, as well as those concerned with the effects of climate change on our environment and the food industry.




Agro-industrial Perspectives on Sugarcane Production under Environmental Stress


Book Description

This edited volume focuses on the core aspects of sugarcane production-management under stressful environments as well as innovative strategies for augmenting crop growth & productivity through intrinsic and extrinsic manipulations. The various chapters aim at bringing out comprehensive and advance information on different aspects of sugarcane cultivation under stress environments and impact of climate change on the sustainability of sugarcane production. The book encompasses information about crop production management, physiological & nutritional requirements, ratooning, ripening and post-harvest losses management. It also delineates various technologies that support the continued use and improvement of sugarcane as renewable source of food, fiber and bio-energy. The manipulations at cellular and molecular levels, molecular breeding approaches and post-harvest technologies are also included. The area under sugarcane cultivation is gradually increasing because of its diversification potential. The high productivity and biomass of the cane crop also makes it a key source for use as bio-energy crop and a promising raw material for bio-based agro-industries. However, poor crop & biomass productivity due to abiotic stress is the foremost constraint in its future commercial exploitation as sustainable feed-stock for bio-based industries. It is therefore imperative to understand the cellular-molecular modulation responsible to productivity barrier under specific stress situation(s) for better sugarcane quality and quantum under field condition. Some of these innovative approaches are delineated in this book. This book is of interest to progressive sugarcane growers, millers, industrial entrepreneurs, sugarcane scientists, cane development and extension officers, sugar industry managers and valuable source of reference worldwide.

Sustainable Agriculture for Food Security


Book Description

Sustainable Agriculture for Food Security: A Global Perspective takes an analytical approach to issues related to current agricultural practices. It looks at global geographical data and key statistical reports to aid readers in comparing, understanding, and making agricultural decisions. The book is divided into chapters with each dealing with a specific problem and its solutions, keeping in mind the context of geographical variations. The book first provides a historical overview of the socioeconomic importance of agriculture around the world along with a discussion on threats and opportunities in the agricultural sector. It goes on to explore the importance of water sources for agriculture, including rain-fed agriculture practices, water harvesting techniques, sustainable irrigation practices, and irrigation water management. Guidance on the usage of agrochemicals and solutions to their detrimental effects from non-standardized consumption is also addressed. The volume also includes a discussion on organic farming methods, certification standards, and key restrictions in crop production. Part 2 goes on to examine postharvest management practices used in different geographical areas along with analysis on the role of technology and obstacles in implementation. The commercialization of agriculture through food processing, branding, and retailing is reviewed along with suggestions on available marketing platforms and promotional aspects. It goes on to outline the situational analysis of food adulteration as well as norms and regulations of food security at the international level. Lastly, the concept of biofortification is explained along with methods and strategies of biofortified food production. The impact of biofortification over socioeconomic development of a specific country is also analyzed.

Probiotics and Plant Health


Book Description

This book primarily focuses on microbial colonization, its role in plant growth and nutrient cycling, mycorrhizae, and providing an overview of phytospheric microorganisms in sustainable crop systems.
