This book was released on with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: First, this paper shows that rice varietal development in Nigeria has been lagging behind that of other developing countries in Asia and Latin America, due partly to insufficient investment in domestic rice R&D. The paper then illustrates using a household model simulation that impacts of certain policies, such as the seed subsidy, may be greater (smaller) if they are applied to good (poor) varieties. The paper concludes by discussing key policy implications and future research needs.
Download or read book Varietal development and the effectiveness of seed sector policies written by Takeshima, Hiroyuki and published by Intl Food Policy Res Inst. This book was released on 2016-10-04 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed is an essential input in agriculture, and the availability of quality seed of superior varieties is often critical for improved food security and poverty reduction in developing countries like Nigeria. However, while the Nigerian government recognizes the importance of improving seed availability, its recent focus in the seed sector has mostly been on improving seed quality rather than on varietal development. This report argues that this is partly due to a knowledge gap regarding the relationship between varietal technology levels and the effectiveness of seed sector policies. We first provide a brief conceptual discussion on how the effectiveness of selected seed sector policies, such as certification, subsidies, and private sector promotion, may depend on underlying varietal technology levels. Using rice as an example, we then provide key historical and international perspectives on how varietal technology development by the public sector through intensive rice breeding had pre-ceded the expansion of seed certification and testing, and show that there still is a substantial need for the Nigerian government to develop improved rice varieties through intensified domestic plant breeding in order for its seed certification and seed subsidy programs to be more effective.

Download or read book Rice Science and Development Politics written by Robert S. Anderson and published by Oxford [England] : Clarendon Press. This book was released on 1991 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1960, the International Rice Research Institute (IRRI) opened near Manila in the Philippines. It's goal was to help solve world food problems in such a way that the foundations' economic and political concerns about Asia would be allayed. This book is about IRRI's planning and development, the efforts to persuade Asian governments to try to increase food production by following IRRI's advice and the interplay of IRRI's technology, rice scientists, and national research strategies. Focusing on conditions in Sri Lanka and Bangladesh, this study testifies to the necessity that the fundamental diversity of rice agriculture should be the organizing principle for an adequate research strategy and shows how strategies which are based on other organizing principles have met continuous difficulties and have ultimately been revised or abandoned. This book will be of particular interest to development and agricultural economists and sociologists.

Download or read book Examining the sense and science behind Ghana s current blanket fertilizer recommendation written by Chapoto, Antony and published by Intl Food Policy Res Inst. This book was released on 2014-07-31 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper was written to help bolster the case and present visual evidence demonstrating why it is important to seriously consider spatial soil fertility variability in Ghana and to promote area-specific fertilizer recommendations. Using geostatistical analysis of soil samples collected from farmer plots in three districts (Tamale Municipality, Savelugu-Nanton, and West Mamprusi in northern Ghana), the paper analyzes spatial variations in soil fertility. The results clearly show that there are variations in soil pH, organic matter content, and available phosphorous even at the community level, supporting the need for Ghana to seriously consider location-specific fertilizer recommendations.
Download or read book Seed Policy and Programmes for Asia and the Pacific written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2000 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents the proceedings a meeting organized and implemented by the Asia & Pacific Seed Association and the Department of Agricultural Extension of the Ministry of Agriculture in Bangkok, Thailand in close collaboration with the Seed and Plant Genetic Resources Service of the FAO. In line with the Rome Declaration on World Food Security and the World Food Summit Plan of Action, the Meeting recognized that one of the major challenges facing most countries in Asia and the Pacific is the need to invest significant resources into strengthening their capacity to increase the availability of good quality seeds of a wider range of plant varieties. This will contribute to the maximization of both agrobiodiversity and productivity, in order to achieve national food security while reducing environmental degradation and the depletion of natural resources. The Meeting proposed and agreed to establish a regional seed network to facilitate the exchange of information and expertise among countries and to coordinate policies and programmes designed to strengthen and improve local seed production and distribution systems in Asia and the Pacific. The Seed Network for Asia and the Pacific (SNAP) will facilitate inter-country scientific and technical collaboration on seed production and supply, and promote crop genetic resources evaluation, conservation and utilization in the region.
Download or read book Agriculture for development in Iraq Estimating the impacts of achieving the agricultural targets of the national development plan 2013 2017 on economic growth incomes and gender equality written by Al-Haboby, Azhr and published by Intl Food Policy Res Inst. This book was released on 2014-05-30 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper estimates the potential effects of achieving the agricultural goals set out in Iraqs National Development Plan (NDP) 20132017 using a dynamic computable general equilibrium model. The findings suggest that raising agricultural productivity in accordance with the NDP may more than double average agricultural growth rates and add an average of 0.7 percent each year to economywide gross domestic product during the duration of the plan. As a consequence, the economy not only diversifies into agriculture, but agricultural growth also lifts growth in the food processing and service sectors. Achieving the yield targets for cereals (especially wheat) and for fruits and vegetables will have the largest impact on economic growth and household incomes. Household incomes will rise by an estimated 3.3 percent annually. This increase in household incomes will benefit the poorest households and female-headed urban households the most due to a combination of lower food prices and higher incomes from labor and land. Reaping these benefits from agricultural growth will critically depend on the implementation of policies and investments to ensure that additional agricultural produce can be marketed efficiently domestically and compete with imports.
Download or read book Women s individual and joint property ownership written by Doss, Cheryl and published by Intl Food Policy Res Inst. This book was released on with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly, womens property rights are seen as important for both equity and efficiency reasons. While there has been debate in the literature about women are better off with individual rights in contrast to rights jointly with their husband, little empirical work has analyzed this question. In this paper, the relationship of womens individual and joint property ownership and the level of womens input into household decisionmaking is explored with data from India, Mali, Malawi, and Tanzania. In the three African countries, women with individual landownership have greater input into household decisionmaking than women whose landownership is joint; both have more input than women who are not landowners. The relationship with other household decisions is more mixed, as is the relationship between housing and input into household decisionmaking. No similar relationship is found in Orissa, India.

Download or read book Closing Rice Yield Gaps in Asia written by Melanie Connor and published by Springer Nature. This book was released on 2023-10-04 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book contributes not only to the scientific literature on sustainable agricultural development and in particular rice agriculture but also is highly valuable to assist practitioners, projects, and policymakers due to its sections on reducing carbon footprint, agricultural innovations, and lessons learned from a multi-country/multi-stages development project. The scope of the book is conceived as a detailed documentation of the implementation, dissemination, and impact of the CORIGAP project in Sri Lanka, Myanmar, Thailand, China, Vietnam, and Indonesia, with spill-over to Cambodia and the Philippines. It pulls together actionable research findings with the experience of bringing these findings into use. The aim of the book is to provide a wide array of pathways to impact for sustainable rice production in lowland irrigated rice-based agricultural systems. The book is written by local actors of the rice value chain, researchers, and engineers working on a range of best management practices, climate-smart rice production innovations, knowledge translation, and dissemination, as well as decision-making and policy aspects. It is envisioned that the contents of the book can be translated into messages that can help farmers, extension workers, policymakers, and funders of agricultural development, decide on implementing best management practices and climate-smart technologies in their agroecological systems by presenting the technological/practical options along the rice value chain and the partnerships and business models required for their implementation. The book is aimed at practitioners, extension specialists, researchers, and engineers interested in information on current best management practices, sustainable, and climate-smart rice production and constraints that need further investigation. Furthermore, the book is also aimed at policymakers and agricultural development funders required by public opinion and legally binding agreements to reduce greenhouse gas emissions, conserve biodiversity and increase agroecological practices, who are looking for research-based evidence to guide policymaking and implementation.
