In the 1980s and 1990s, green manure/cover crop (GMCC) systems became a popular agricultural technology in research and development efforts for smallholder tropical and subtropical farmers. However, few syntheses of these experiences have been conducted. This volume of case studies contributes to bridging this gap by reviewing field-level experiences with these systems. Twelve case studies are included. Eleven of them describe experiences from Latin America (4 cases), Africa (6 cases) and Asia (1 case) and the twelfth case reports on the development of a GMCC systems database. Two concluding chapters, `Learning from the Case Studies' and `Future Perspectives', build upon the cases. The systems described are diverse. Some systems have been spontaneously adopted by farmers, while others have been introduced to the farmers through diffusion efforts. Some of the cases reviewed describe small, localized efforts while others report on large-scale, well-known ones, such as the combination of GMCCs and conservation tillage in Santa Catarina, Brazil, the maize-Mucuna system in northern Honduras, and the improved fallow systems in Eastern Zambia. Most experiences include both development and research aspects and to the extent possible the cases integrate these two. Discussion of the strengths and shortcomings of the systems and efforts is frank, and the goal is to learn from these experiences to benefit future efforts. It is expected that both researchers and development practitioners and students of tropical farming systems and soil management will find this volume of case studies useful.

From the pre-Columbian era to the present, native Amazonians have shaped the land around them, emphasizing utilization, conservation, and sustainability. These priorities stand in stark contrast to colonial and contemporary exploitation of Amazonia by outside interests. With essays from environmental scientists, botanists, and anthropologists, this volume explores the various effects of human development on Amazonia. The contributors argue that by protecting and drawing on local knowledge and values, further environmental ruin can be avoided.

Tropical ecosystems are some of the most biologically and ecologically diverse in the world. Traditional, local agroecosystems in the tropics reflect this diversity, and provide excellent examples of how nature can be used as the model for designing and managing sustainable agroecosystems. This book brings together such examples. Using an agroecological approach, the collection of chapters demonstrates how agroecology must simultaneously be a science, a practice, and a movement for social change towards a paradigm of sustainability that engages all parts of the food system, from the field to the table. Chapter contributors were selected from multiple countries and backgrounds, providing a valuable diversity of approaches and knowledge systems, and the interaction of these systems gives this book the important transdisciplinarity that has become a key component of agroecology. Working across disciplines and knowledge systems is necessary in order to link the multiple components of food systems that promote effective change. As food systems return to the diversity, complexity, and resilience they once had, it is collections of experiences as presented in this book that provide examples of the path we must be on.

Nearly two billion people depend on hundreds of millions of smallholder farmers for food security. Yet, these farmers’ lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. Soil Management of Smallholder Agriculture explores the potential smallholder agriculture hold for advancing global food security and outlines the challenges to achieving this goal. The book addresses the challenges and opportunities that resource-poor and small landholders face and provides recommended management practices to alleviate soil-related constraints, and increase and sustain crop yield and production. It discusses the cultural, economic, social, and technological aspects of sustainable soil management for smallholder farmers. It then examines soil-related and institutional constraints, principles of sustainable agriculture, soil quality improvement, nutrient and soil fertility management, soil carbon sequestration, soil security, efficient use of resources, and agronomic production. Edited by experts, the book makes the case for the adoption of proven technologies of sustainable intensification, producing more from less, both for advancing agronomic production and adapting to changing climate. It outlines a strategy that will usher in a soil-based Green Revolution by increasing the use efficiency of energy-based inputs such as fertilizers, pesticides, and irrigation to restore soil quality, and sequestering carbon in the terrestrial ecosystems. This strategy helps small farms narrow the gap between the actual and attainable crop yield.

This 35-chapter book is based on several oral and poster presentations including both invited and contributory chapters. The book is thematically based on four pillars of sustainability, with focus on sub-Saharan Africa (SSA): Environment, Economic, Social and Institutional. The environmental sustainability, which determines economic and social/institutional sustainability, refers to the rate of use of natural resources (soil, water, landscape, vegetation) which can be continued indefinitely without degrading their quality, productivity and ecosystem services for different ecoregions of SSA. This book will help achieve the Sustainable Development Goals of the U.N. in SSA. Therefore, the book is of interest to agriculturalists, economists, social scientists, policy makers, extension agents, and development/bilateral organizations. Basic principles explained in the book can be pertinent to all development organizations.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.
