This book presents lessons from farmer-managed [not indigenous] and government-managed irrigation systems worldwide and proposes workable approaches to participatory irrigation management in both the large- and small-scale contexts. It discusses the need for greater farmer participation in irrigation management.

In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon dioxide have led to a severe depletion of the carbon pool in the world's soils. This is especially telling in developing countries where tropical climates further compromise the soil's ability to recover.In Climate Change and Global Food Security, bestselling editor Rattan Lal heads up a team of the world's top soil scientists and ecologists to document the history of this impending agricultural crisis and explore possible solutions. Throughout this timely text, the authors address six complex themes:1. The impact of projected climate change on soil quality, water resources, temperature regime, and growing season duration on net primary productivity of different biomes2. Soil carbon dynamics under changing climate3. The impact of changes in carbon dioxide and ecological environments on agronomic yields and food production in different regions of the world4. World food demands and supply during the 21st century5. Policy and economic issues related to carbon trading and enhancing agricultural production6. Research and development priorities for enhancing soil carbon pool and food securityThis hard-hitting text is essential reading for anyone involved with soil and crop sciences as well as policy makers and change agents who need to come to the forefront of this issue armed with the latest information and viable solutions.

Agriculture in the 21st century will need considerable modification to remain both productive and sustainable. Greater production is needed to meet the needs of our still-growing populations and to combat hunger and poverty. Declines in soil health and the pollution of water sources are making many of our production systems less tenable. These adverse trends are exacerbated more and more by the impacts of climate change.There are, fortunately, alternative methods available for agricultural practice that can countervail these constraints. Biological Approaches to Regenerative Soil Systems brings together the work of both researchers and practitioners to map out better approaches to contemporary agriculture that draw upon both old and new knowledge. It presents the science that underlies more biologically driven strategies as well as contemporary innovative experiences in diverse parts of the world. Both accepted research and these varied experiences encourage confidence that these approaches, not relying primarily on the introduction of new varieties and on exogenous inputs, can succeed.This book updates and revises a preceding volume Biological Approaches to Sustainable Soil Systems published by CRC Press in 2006. So much has been learned and done on this subject in the past decade and a half that a second edition was warranted. For instance, the first edition was published, knowledge about plant-soil microbiomes, which are a frequent focus in this book, has mushroomed.Because sustainability is a broad term and an end-state, the editors preferred to assemble expertise regarding regenerative agriculture, which is concerned with the means for achieving sustainability. The concept of regenerative soil systems, entities that are more complex and multifaceted than "soil" alone, also incorporates a concern with having more resilient agricultural systems, ones that are better able to cope with the multiple stresses of climate change that are foreseen for the decades ahead.The book’s chapters representing a wide range of disciplines were contributed by 84 scientists and practitioners from 20 countries. Although they come from persons with in-depth knowledge of their respective fields, the chapters are written to be accessible to readers who are not trained in the specialized subjects. Taken together, the chapters provide students, researchers, practitioners, planners, and policy makers with a comprehensive understanding of both the science and the steps needed to regenerate and sustain soil systems around the world for the long-term benefit of humankind and the environment.

Addressing a topic of major importance to the maintenance of world food supplies, this reference identifies knowledge gaps, defines priorities, and formulates recommendations for the improvement of the rice-wheat farming system. The book reveals new systems of rice intensification and management and illustrates the application of no-till and conservation farming to the rice-wheat system. With contributions from 65 international experts, and case studies from India, Nepal, Pakistan, and Bangladesh, Sustainable Agriculture and the International Rice-Wheat System focuses on seeding equipment and residue management, weed control, water and nutrient efficiency, and integrated pest management.

Can developing countries meet the food requirements of their growing populations without jeopardizing a natural resource base that is already under great stress?Can increases in food production achieved in the past two decades be sustained in the next two decades?Can developing countries achieve freedom from hunger and malnutrition for their entire populations?How can food security be reconciled with environment quality in an industrializing society?Leading authorities, from soil scientists to economists, address these critical questions in Food Security and Environmental Quality in the Developing World. With a focus on India, this book reviews the state of natural resources, fertilizer and energy needs, and the potential importance of biotechnology as they affect all developing countries. It then addresses issues pertaining to water quality, agricultural chemicals, and pesticide residues on food. Part Three examines water harvesting, post-harvest food losses, storage and processing of animal products, and sustainability and inequality issues. The next sections deal with poverty alleviation, microfinance, gender equity, policy issues, and the role of the public sector. Finally, the book considers emerging issues and priorities.Developing countries have achieved an impressive increase in total food production over the past two decades, but at a high cost to environmental quality. As the populations of these countries continue to grow, soil degradation, pollution and contamination of natural waters, deteriorating air quality, and growing dependence on expensive and diminishing fossil fuels become increasing concerns. Food Security and Environmental Quality in the Developing World takes on the crucial challenge of enhancing agricultural production while reversing the alarming trends in soil and environmental degradation.

The world's food supply needs to rise significantly, yet both arable and water supplies per capita are decreasing. Not only are modern agricultural methods beyond the reach of those suffering the greatest food insecurity but they are also ecologically damaging, relying upon fossil energy and chemical inputs. This volume offers a collection of innovative and diverse approaches to agricultural development. Documented in 12 case studies, these approaches are reliant upon greater knowledge, skill and labour input, rather than larger capital expenditure. They are shown to increase yield substantially, sometimes doubling or tripling output. This volume presents the concepts and operational means for reorienting agricultural efforts towards these more environmentally friendly and socially desirable approaches in the developed as well as developing world.
