Download or read book Guide to Participatory Varietal Selection for Submergence tolerant Rice written by T. R. Paris and published by IRRI. This book was released on 2011 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Green Revolution averted the threat of famine through the rapid adoption of improved rice varieties. However, despite this huge success, hundreds of millions of poor rice-farming families in rainfed areas still live in poverty and suffer from food (rice) insecurity. Despite many released improved rice varieties for rainfed conditions, farmers still use local varieties that can withstand drought and floods but have low yields or they use the same varieties for many years because of a lack of better varieties. Rainfed rice farmers are slow to adopt improved varieties because of several problems. One problem is more of extension than breeding - many farmers, particularly those living in remote rainfed areas, may not have access to or information about the seed of new varieties. Another problem is that variety testing programs are often conducted on-station, which does not represent farmers' fields. Moreover, conventional rice breeding programs usually seek farmers' input only at the very end of the process, when newly released varieties, usually one or two per year, are evaluated in on-farm demonstration trials. Often, in remote and unfavorable areas, subsistence farmers, who comprise the majority of the rural farming population in Asia, give importance to social and cultural dimensions aside from the agronomic performance of the new rice varieties. The complexities of developing acceptable varieties for variable and stressful rainfed environments require that breeders become deeply familiar with men and women farmers' needs and preferences. Since 1977, IRRI has been making efforts to improve communication among farmers, breeders, and extension workers so that men and women farmers' concerns and preferences are considered in plant breeding objectives. Participatory varietal selection (PVS) is a simple way for breeders and agronomists to learn which varieties perform well on-station and on-farm and to obtain feedback from the potential end users in the early phases of the breeding cycle. It is a means for social scientists to identify the varieties that most men and women farmers prefer, including the reasons for their preference and constraints to adoption. Based on IRRI's experience in collaboration with national agricultural research and extension system partners and farmers, PVS, which includes "researcher-managed" and "farmer-managed" trials, is an effective strategy for accelerating the dissemination of stress-tolerant varieties. PVS has also been instrumental in the fast release of stress-tolerant varieties through the formal varietal release system. This guide on PVS will complement the various training programs given by IRRI for plant breeders, agronomists, and extension workers engaged in rice varietal development and dissemination.

Download or read book Women Farmers Unheard Being Heard written by Sugandha Munshi and published by Springer Nature. This book was released on 2023-06-11 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume celebrates the positive stories and small changes happening with respect to gender equality in the field of agriculture. This book identify crisis which a woman faces in the field of agriculture as a farmer. The book shares unsung stories of women farmers who are bringing change at the grassroots. It puts together the positive developments experienced by the experts, researchers, professional while working for and with women farmers, to highlight the challenges to bring equity in agriculture. Women in agriculture often lack identity where either they are recognized as farmer’s wife or a farm labourer. Women farmers who contribute 60 percent in to farm practices like sowing, transplanting, fertilizer application, weeding, harvesting, winnowing are merely recognised and provided an equal level playing field. Women are also found participating in the various forms of processing and marketing of agriculture produce, along with the cultivation but system has failed to protect their rights and offer them a platform to voice their concerns. This book shares the process, challenges, experience, strategy from the narrative of progressive women farmers so as to highlight and understand what it takes to bring changes for achieving the goals of an equitable farming ecosystems. The book is a relevant reading material for students, researchers, professionals and policy advocates in agriculture and gender research.

Download or read book Farmers and Plant Breeding written by Ola Tveitereid Westengen and published by Routledge. This book was released on 2019-10-02 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the history of, and current approaches to, farmer-breeder collaboration in plant breeding, situating this work in the context of sustainable food systems, as well as national and international policy and law regimes. Plant breeding is essential to food production, climate-change adaptation and sustainable development. This book brings together experienced practitioners and researchers involved in collaborative breeding programmes across a diversity of crops and agro-ecologies around the world. Case studies include collaborative sorghum and pearl millet breeding for water-stressed environments in West Africa, participatory rice breeding for intensive rice farming in the Mekong Delta, and evolutionary participatory quinoa breeding for organic agriculture in North America. While outlining the challenges, the volume also highlights the positive impacts, such as yield increases, farmers’ empowerment in the innovation and development processes, contributions to maintenance of crop genetic diversity and adaptation to climate change. This collection offers a range of perspectives on enabling conditions for farmer–breeder collaboration in plant breeding in relation to biodiversity agreements such as the Plant Treaty, trade agreements and related intellectual property rights (IPR) regimes, and national seed policies and laws. Relevant to a wide audience, including practitioners with experience in plant breeding and management of crop genetic resources and those with a broader interest in agriculture and development, as well as students of international cooperation and development, this volume is a timely addition to the literature.
Download or read book Ensuring a Square Meal written by Devasahayam Theresa W and published by World Scientific. This book was released on 2018-08-20 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on women and food security in Southeast Asia has been limited. The collection of chapters in Ensuring a Square Meal: Women and Food Security in Southeast Asia is one of the first attempts at providing a lens into the linkages between women and food security at the household, community, national, and transnational levels. More broadly, the chapters examine women's contribution in households, resource distribution to produce food, and the purchasing power to buy food. In analysing the various facets of food security in relation to gender, the analyses focus on the meanings of 'private' and 'public', and the extent to which the effects of the two spheres spill over into each other. Given women's critical role in food production and provision, the book assesses the structural forces enabling women to access productive resources and, in turn, ensure sustainable strategies for food security; as well as it evaluates how governments might address the constraints women face in this vital role.

Download or read book Community Seed Banks written by Ronnie Vernooy and published by Routledge. This book was released on 2015-05-15 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
