Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country. Surprisingly, despite 25 years of history and the rapid growth in number, organizational diversity and geographical coverage of community seed banks, recognition of their roles and contributions has remained scanty. The book reviews their history, evolution, experiences, successes and failures (and reasons why), challenges and prospects. It fills a significant gap in the literature on agricultural biodiversity and conservation, and their contribution to food sovereignty and security.

Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.

Charting the political, social, and environmental history of efforts to conserve crop diversity. Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect fruits, grains, and vegetables they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative that concerns the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to uncover this hidden narrative and show how it shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how those who sought to protect native, traditional, and heritage crops forged their methods around the expectation that social, political, and economic transformations would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity.

Farmers' Rights are essential for maintaining crop genetic diversity, which is the basis of all food and agricultural production in the world. The International Treaty on Plant Genetic Resources for Food and Agriculture recognizes Farmers' Rights and provides for relevant measures. However, implementation is slow, and in many countries there is resistance. This book shows the necessity of realizing Farmers' Rights for poverty alleviation and food security, the practical possibilities of doing so, and the potential gains for development and society at large. It provides decision-makers and practitioners with a conceptual framework for understanding Farmers’ Rights and success stories showing how each of the elements of Farmers' Rights can be realized in practice. The success stories have brought substantial achievements as regards one or more of the four elements of Farmers' Rights: the rights of farmers to save, use, exchange and sell farm-saved seed; the protection of traditional knowledge; benefit- sharing; and participation in decision-making. This does not mean that these examples are perfect. Challenges encountered on the way are conveyed and offer important lessons. The stories represent different regions and localities, including Europe, Asia, Africa and Latin America, as well as various categories of stakeholders and types of initiatives and policies.

What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.

Over the last 50 years there has been a growing appreciation of the important role that farmers play in the development and conservation of crop genetic diversity, and the contribution of that diversity to agro-ecosystem resilience and food security. This book examines policies that aim to increase the share of benefits that farmers receive when others use the crop varieties that they have developed and managed, i.e., ‘farmers varieties’. In so doing, the book addresses two fundamental questions. The first question is ‘how do farmer management practices – along with other factors such as environment and the breeding systems of plants – affect the evolution and maintenance of discrete farmers’ varieties?’ The second question is ‘how can policies that depend on being able to identify discrete plant varieties accommodate the agricultural realities associated with the generation, use and maintenance of farmers’ varieties?’ This focus on discreteness is topical because there are no fixed, internationally recognized taxonomic or legal definitions of farmers’ varieties. And that presents a challenge when developing policies that involve making specific, discrete farmers’ varieties the subject of legal rights or privileges. The book includes contributions from a wide range of experts including agronomists, anthropologists, geneticists, biologists, plant breeders, lawyers, development practitioners, activists and farmers. It includes case studies from Asia, Africa, Latin America and Europe where, in response to a diversity of contributing factors, there have been efforts to develop policies that provide incentives or rewards to farmers as stewards of farmers’ varieties in ways that are sensitive to the cultural, taxonomic and legal complexities involved. The book situates these initiatives in the context of the evolving discourse and definition of ‘farmers' rights’, presenting insights for future policy initiatives.
