How can cultivated plant biodiversity contribute to the transformation and the "ecologization" of agriculture in Southern countries? Based on extensive field work in the Southern countries, a great deal of scientific progress is presented in all areas affecting agriculture (agronomy, plant breeding and crop protection, cultivation systems, etc.) in order to intensify the ecological processes in cultivated plots and at the scale of rural landscapes.

Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics. Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. This book brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Some critics have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, the book shows that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment and local communities. The book focuses on successful agricultural strategies of upland farmers, particularly in south and south-east Asia, and presents over 50 contributions by scholars from around the world and from various disciplines, including agricultural economics, ecology and anthropology. It is a sequel to the much praised "Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming" (RFF Press, 2007), but all chapters are completely new and there is a greater emphasis on the contemporary challenges of climate change and biodiversity conservation.

Farming for Our Future examines the policies and legal reforms necessary to accelerate the adoption of practices that can make agriculture in the United States climate-neutral or better. These proven practices will also make our food system more resilient to the impacts of climate change. Agriculture's contribution to climate change is substantial--much more so than official figures suggest--and we will not be able to achieve our overall mitigation goals unless agricultural emissions sharply decline. Fortunately, farms and ranches can be a major part of the climate solution, while protecting biodiversity, strengthening rural communities, and improving the lives of the workers who cultivate our crops and rear our animals. The importance of agricultural climate solutions can not be underestimated; it is a critical element both in ensuring our food security and limiting climate change. This book provides essential solutions to address the greatest crises of our time.

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.

Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science. Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems. This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

This book examines the challenges and impacts of poor diets and nutrition from current food systems and the potential contribution of biodiversity and ecosystem services in addressing these problems. There is a strong need for a multi-level, cross-sectoral approach that connects food biodiversity conservation and sustainable use to address critical problems in our current food systems, including malnutrition. Building on research from the Biodiversity for Food and Nutrition Project (BFN), which aims to better link biodiversity, diets and nutrition, the book presents a multi-country, cross-sectoral analysis of initiatives that have promoted local food biodiversity in four countries: Brazil, Kenya, Turkey and Sri Lanka. This book offers a comprehensive summary of the BFN Project results in each of the four countries along with lessons learned and how this work could be upscaled or applied in other regions. It argues that the strategic promotion and use of food biodiversity is critical in uniting attempts to address conservation, nutrition and livelihood concerns. The book is structured around chapters and case studies encompassing the BFN Project with specific experiences related by partners who played key roles in the work being done in each country. By offering a comparative view capable of furthering dialogue between the respective countries, it is also meant to connect the individual cases for a “greater than the sum of its parts” effect. This means consideration of how localized activities can be adapted to more countries and regions. Therefore, the book addresses global issues with a foot planted firmly in the grounded case study locations. This book will be of great interest to policymakers, practitioners and NGOs working on food and nutrition, as well as students and scholars of agriculture, food systems and sustainable development.

While modern science has always recognized the central role that biodiversity plays in the ecological processes that maintain the Earth's equilibrium, our increasing knowledge of nature has deepened our appreciation of this principle. Consequently, those involved with implementing and maintaining sustainable agriculture systems have begun to take a far more sophisticated approach to understanding and making use of the components and mechanics of biodiversity. Providing a comprehensive and highly practical exploration of the subject, Biodiversity in Agricultural Production Systems examines abiotic ecosystem diversity and biological complexity at every relevant level. Leading researchers detail subspecies diversity, covering ecotypes, lifecycles, genes, physiology, and behavior. They also discuss species richness and supraspecies diversity, which includes foodweb interactions and non-trophic relationships, as well as above- and belowground relationships. Exploring various facets of agricultural crops and cultivation practices, this inter-disciplinary volume- Gives an overview of the pore space dynamic in agroecosystems where most soil microorganisms reside, including bacteria, fungi, protozoa, nematodes, and Tardigrada Examines the highly diverse and prominent role played by earthworms Looks at the metabolic processes occurring in soils that result in the release of greenhouse gases Outlines principles and strategies of order between interacting molecules, cells, species and communities Looks at mechanisms of competition, exploring growth regulation, transformation, and feeding strategies, as well as toxin production, mutation, and biofilm formation Discusses matter recycling and the diversity of microbial metabolism in soils Shows how long-term observation plots are used to assess soil quality Biodiversity in Agricultural Production Systems provides important information for those involved with researching and implementing sustainable agricultural systems, as well as those addressing specific challenges related to soil degradation, water management, and climatic impacts. It also provides recent research and fresh perspectives to enhance the approaches of those working in horticulture, biology, and the environmental sciences.

"Sustainability is at the heart of FAO's new Strategic Framework and is the specific focus of Strategic Objective 2, which aims at sustainably increasing the provision of goods and services from agriculture, forestry and fisheries. This report is the outcome of intensive consultations and discussions aimed at developing a common approach to FAO's work on sustainability. That process was conducted in a climate of cross-sectoral collaboration that drew on the contributions of leading FAO and external specialists in crops, livestock, forestry, capture fisheries, aquaculture and natural resources. The report provides the vision, the key principles and indications on the way forward to transition towards sustainable food and agriculture. It builds on the Organization's long experience in developing sustainability concepts, approaches and tools, and offers a common platform for a vision of the agriculture sector and of the inter-sectoral synergies that will eventually make agriculture more productive and sustainable."--Publisher's information.

Award-winning journalist Simran Sethi explores the history and cultural importance of our most beloved tastes, paying homage to the ingredients that give us daily pleasure, while providing a thoughtful wake-up call to the homogenization that is threatening the diversity of our food supply. Food is one of the greatest pleasures of human life. Our response to sweet, salty, bitter, or sour is deeply personal, combining our individual biological characteristics, personal preferences, and emotional connections. Bread, Wine, Chocolate illuminates not only what it means to recognize the importance of the foods we love, but also what it means to lose them. Award-winning journalist Simran Sethi reveals how the foods we enjoy are endangered by genetic erosion—a slow and steady loss of diversity in what we grow and eat. In America today, food often looks and tastes the same, whether at a San Francisco farmers market or at a Midwestern potluck. Shockingly, 95% of the world’s calories now come from only thirty species. Though supermarkets seem to be stocked with endless options, the differences between products are superficial, primarily in flavor and brand. Sethi draws on interviews with scientists, farmers, chefs, vintners, beer brewers, coffee roasters and others with firsthand knowledge of our food to reveal the multiple and interconnected reasons for this loss, and its consequences for our health, traditions, and culture. She travels to Ethiopian coffee forests, British yeast culture labs, and Ecuadoran cocoa plantations collecting fascinating stories that will inspire readers to eat more consciously and purposefully, better understand familiar and new foods, and learn what it takes to save the tastes that connect us with the world around us.
