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.

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 Synopsis Guide to Participatory Varietal Selection for Submergence-tolerant Rice by : T. R. Paris
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.
Book Synopsis Factors Influencing Hybrid Rice Adoption by : Khondoker Mottaleb
Download or read book Factors Influencing Hybrid Rice Adoption written by Khondoker Mottaleb and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As rice constitutes the major share in cereal consumption in South and East Asian countries that ranges from as low as 40 per cent in India to 97 per cent in Myanmar, to ensure food security, governments in these countries are encouraging farmers to adopt hybrid rice. This is mainly because hybrid rice provides a yield gain of 15-20 per cent over conventionally bred varieties in general. Yet, despite strenuous government efforts, farmers' adoption rates have remained low in India, Bangladesh and Vietnam compared with China. Although studies often claim that higher seed costs and inferior grain quality are the major factors limiting hybrid rice adoption, very few studies examine the importance of socio-economic factors and infrastructure in the adoption of hybrid rice. Using Bangladesh as a case, a comparative analysis has been made on the adoption of hybrid and modern varieties relative to traditional rice varieties and land allocation to these varieties. Econometric results indicate that general land characteristics, loan facilities and general infrastructure, such as roads, irrigation facilities and the availability of government-approved seed dealers, significantly influence the adoption of hybrid and modern rice varieties and land allocation to these varieties compared with traditional varieties.
Book Synopsis Rice Productivity and Food Security in India by : Poornima Varma

Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the adoption of agricultural technology in general and to literature on the System of Rice Intensification (SRI) in particular by identifying the factors that influence the decision to adopt SRI and examining SRI’s impact on household income and yield. The study also discusses the importance of SRI in achieving higher rice productivity and food security. Conducted on behalf of the Government of India’s Ministry of Agriculture from October 2014 to March 2016, the study collected detailed and extensive household-level data. As the second largest producer and consumer, India plays an important role in the global rice economy. Food security in India has been traditionally defined as having a sufficient supply of rice at an affordable price. However, in recent years rice cultivation in India has suffered from several interrelated problems. Increased yields achieved during the green revolution period and with the help of input-intensive methods involving high water and fertiliser use are now showing signs of stagnation and concomitant environmental problems due to salinisation and waterlogging of fields. Water resources are also limited; as such, water for irrigation must contend with increasing industrial and urban needs. As a result of all these factors, rice farmers have experienced a downturn in productivity growth. Since increasing the area of rice cultivation is not feasible, the additional production has to be achieved using less land, less water and fewer additional inputs. The new intensification methods for rice cultivation known as the System of Rice Intensification (SRI), which originated in Madagascar, offer a promising systemic approach to enhancing rice production at affordable costs by simultaneously reducing input requirements and causing less harm to the environment. The SRI approach is expected to enhance yield and substantially reduce water and other input requirements by altering plant, soil, water and nutrient management practices. With SRI taking firm root in India, the book examines and analyses the adoption and the economic impact of SRI in three major rice producing States of India: Karnataka, Madhya Pradesh and Orissa.

Download or read book Agrobiodiversity - a training manual for farmer groups in East Africa written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-26 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers play a crucial role in the preservation and sustainable use of agrobiodiversity. In fact, the diversity of species that support our current agricultural production systems has been carefully managed and shaped by farming communities, over the course of the history of humankind. Farmers act as custodian of the Earth’s agrobiodiversity resources, and play a big part in preserving traditional plant and animal varieties, and the knowledge associated with these. FAO has long been working on promoting approaches to agriculture that enable both the sustainable use of biodiversity resources for food and agriculture, and their conservation, and on supporting farmers to make informed decisions on their farm management and production practices. This training manual fits in this broader commitment, to support a shift towards a paradigm of agricultural production that can sustain food and nutrition security while at the same time cause the least harm to natural ecosystems. The manual is intended as an introduction to agricultural biodiversity, and to its relevance to different aspects of agricultural production and management for smallholder farmers in Kenya. It includes eight different training modules, each covering a specific aspect related to agrobiodiversity. The modules are standalone and can be used independently one from the other, depending on the user’s or project’s aim. The materials were originally prepared within the FAO- Netherlands Partnership Programme (FNPP) and have been updated, revised and published under the second phase of the European Union-funded project “Capacity-building related to multilateral environmental agreements (MEAs) in Africa, Caribbean and Pacific (ACP) countries”.
Book Synopsis Water-Energy-Food Nexus by : P. Abdul Salam
Download or read book Water-Energy-Food Nexus written by P. Abdul Salam and published by John Wiley & Sons. This book was released on 2017-07-12 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water, energy and food are key resources to sustain life, and are the fundamental to national, regional and global economies. These three resources are interlinked in multiple ways, and the term “nexus” captures the interconnections. The nexus has been discussed, debated, researched, and advocated widely but the focus is often on the pairings of “water-energy” or “water-food” or “energy-food”. To really benefit from the nexus approach in terms of resource use efficiency it is essential to understand, operationalize and practice the nexus of all three resources. As demand for these resources increases worldwide, using them sustainability is a critical concern for scientists and citizens, governments and policy makers. Volume highlights include: Contributions to the global debate on water-energy-food nexus Examples of the nexus approach in practice from different regions of the world Perspectives on the future of the nexus agenda Water-Energy-Food Nexus: Theories and Practices is a valuable resource for students, research scholars and professionals in academic institutions with strong interests in interdisciplinary research involving geography, earth science, environmental science, environmental management, sustainability science, international development, and ecological economics. The volume will also be useful for professionals, practitioners and consultants in /NGOs, government, and international agencies.
