Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates factors affecting the adoption and diffusion of improved varieties and identifies the determinants of varietal diversification on household farms based on data collected in 2005 in six regions in Bangladesh by the International Rice Research Institute in collaboration with Department of Agricultural Extension in Bangladesh. It was found that varietal diversity was highest in the wet season than in the dry season, when close to 90% of the sample farmers grow more than one variety. The diversity is also high in the regions of Barisal and Chittagong where the proportion of poor population is 44% or greater. Diversity is enhanced in less favored areas in terms of agroecological conditions such as flood prone or drought prone or saline areas. This implies that policy makers should provide appropriate and area-specific interventions and programs so they can cope up with yield losses in these less favored areas. On the other hand, factors associated with lower rice varietal diversity were those farms that have irrigation, and were located in very low land areas. Among the factors found to significantly influence the adoption of modern varieties such as BR 29 are use of irrigation, and varietal traits of high yield, good grain quality, and pest resistance. The importance of these traits should be taken into consideration in the development and introduction of nutritional traits as farmers will adopt new varieties if there is no yield penalty and if good eating quality is maintained.

Book excerpt: This paper investigates the relationship between adoption of modern rice varieties and rice varietal diversity on household farms in Bangladesh. As shown in previous studies, adoption of modern varieties depends on agroecological- and input-related factors, including the availability and use of irrigation facilities, such as tubewells. Having irrigation affects the diversity index significantly and positively, which could be due to the diffusion of more modern varieties (MVs) in areas where irrigation is available and accessible.

This book was released on with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing literature shows that climate change will likely affect several of the dimensions that determine people’s food security status in Bangladesh, from crop production to the availability of food products and their accessibility. Crop diversification represents a farm-level response that reduces exposure to climate-related risks and it has also been shown to increase diet diversity and contribute to the reduction in micronutrient deficiencies. In fact, the Government of Bangladesh has several policies in place that encourage and support agricultural diversification. However, despite this support the level of crop diversification in the country remains low. Women empowerment has been linked to diversified diets and positively associated with better child nutrition outcomes. Furthermore, although traditionally their role in agriculture tends to be undervalued, women involvement has already been shown to affect agricultural production choices and enhance technical efficiency. This paper connects three different areas of inquiry - climate change, gender and nutrition – by exploring whether women’s empowerment in agricultural production leads to increased diversification in the use of farmland. Specifically, we use a series of econometric techniques to evaluate whether there is sufficient evidence to claim that a higher levels of empowerment lead to greater diversity in the allocation of farmland to agricultural crops. Our results reveal that indeed some aspects of women empowerment, but not all, lead to a more diversified use of farmland and to a transition for cereal production to other uses like vegetables and fruits. These findings provide some possible pathways for gender-sensitive interventions that promote crop diversity as a risk management tool and as a way to improve the availability of nutritious crops.

Available in PDF, EPUB and Kindle. Book excerpt: Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality

Download or read book Nutrition sensitive agriculture written by Ruel, Marie T. and published by Intl Food Policy Res Inst. This book was released on 2017-10-27 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A growing number of governments, donor agencies, and development organizations are committed to supporting nutrition-sensitive agriculture (NSA) to achieve their development goals. Although consensus exists on pathways through which agriculture may influence nutrition-related outcomes, empirical evidence on agriculture’s contribution to nutrition and how it can be enhanced is still weak. This paper reviews recent empirical evidence (since 2014), including findings from impact evaluations of a variety of NSA programs using experimental designs as well as observational studies that document linkages between agriculture, women’s empowerment, and nutrition. It summarizes existing knowledge regarding not only impacts but also pathways, mechanisms, and contextual factors that affect where and how agriculture may improve nutrition outcomes. The paper concludes with reflections on implications for agricultural programs, policies, and investments, and highlights future research priorities.
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 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.
