Guinea [In West African agriculture and climate change: A comprehensive analysis]
No full textThe Republic of Guinea covers an area of 245,857 square kilometers divided into seven administrative regions: Kindia, Boké, Mamou, Labé, Faranah, Kankan, and N’Zérékoré. The country consists of four major agroecological regions: coastal (Lower Guinea), middle (Fouta Djallon), upper, and forest Guinea. Guinea has a tropical climate with two alternating seasons, a dry season from November through March and a rainy season from April through October. In general, its rainfall increases from north to south; the mean annual rainfall is 1988 millimeters. Rice is the staple crop, grown on 80 percent of the farms in the country. Rice is cultivated in the upland as well as various lowland ecologies, including inland valley swamps, mangrove swamps, and flooded plains. Other important foodcrops grown and consumed in Guinea are corn, fonio (cultivated grains belonging to the genera Digitaria exilis and Digitaria iburua), groundnuts, and cassava. Exclusively rainfed agriculture is practiced in Guinea, and crop production is significantly influenced by the weather—a growing challenge for resource-poor farmers. The major constraints faced by rice farmers are drought, weeds, and poor soils.PRIFPRI1; CRP7EPTDCGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS
Measuring food policy research capacity: Indicators and Typologies
No full textWe surveyed 30 countries to measure the capacity of their individuals, organizations, and policy process system to undertake food and agricultural policy research. Our Food Policy Research Capacity Index, constructed using measures of human capacity (PhD full-time equivalent researchers per million rural residents), human capacity productivity (publications per PhD full-time equivalent researcher), and strength of institutions (the government effectiveness pillar of the Worldwide Governance Indicators), showed substantial variation across countries, with the Republic of South Africa, Colombia, and Ghana scored far higher than countries with similarly sized rural populations such as Liberia, Laos, Burundi, and Afghanistan.Non-PRIFPRI1; GRP35; A.3 Science, Technology, and innovation PolicyPIC; DSG
Summary of Determinants and impact of sustainable land and watershed management investments
No full textOngoing debate over water resource management and land degradation suggests a need for efficient sustainable land management mechanisms to improve agricultural output in the Blue Nile basin in Ethiopia. Numerous econometric and hydrological models have been developed to assess the effects of sustainable land and watershed management (SLWM) investments. However, these models fail to address the trade-offs faced by rural farmers in maintaining such structures. This study combines household survey data that evaluates the economic determinants of program sustainability with a detailed hydrological model that explores location specific effects of SLWM structures. Simulations suggest that more comprehensive investments (such as SLWM with increased fertilizer application) may reap more economically significant increases in household income. Cost benefit analysis suggests that a packaged investment approach is needed in order to outweigh the opportunity costs (foregone labor, particularly) of investing in SLWM infrastructure at farm level.Non-PRIFPRI2; ESSP; CRP2DSGD; PIM; EPTDCGIAR Research Program on Policies, Institutions, and Markets (PIM
Model description
No full textThe International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) was developed at IFPRI at the beginning of the 1990s to address a lack of long-term vision and consensus among policy-makers and researchers about the actions that are necessary to feed the world in the future, reduce poverty, and protect the natural resource base. In 1993, these same long-term global concerns launched the 2020 Vision for Food, Agriculture, and the Environment Initiative which created the opportunity for further development of the IMPACT model. In 1995 the first results using IMPACT were published as a 2020 Vision discussion paper: Global Food Projections to 2020: Implications for Investment (Rosegrant et al. 1995) in which the effects of population, investment, and trade scenarios on food security and nutrition status, especially in developing countries, were analyzed.
IMPACT continues to serve as the basis for research examining the linkage between the production of key food commodities and food demand and security at the national level in the context of scenarios of future change. Studies focus on regional issues, commodity-level analyses, and cross-cutting thematic issues. IMPACT is also embedded in a variety of major global assessments to complement interdisciplinary, scenario-based work on the future of food supply and demand. The first comprehensive set of results for IMPACT were published in the book Global Food Projections to 2020 (Rosegrant et al. 2001). These projections—which were presented in 2001 at the IFPRI-sponsored conference in Bonn entitled: Sustainable Food Security for All by 2020—are presented with details on the demand system and other underlying data used in the projections work, and cover both global and regionally-focused projections. A complete list of the research published using the IMPACT modeling framework is provided in Appendix 1, including reports for international organizations, such as the World Bank, the Asian Development Bank, the FAO, and national governments.

A roadmap towards a strategy
No full textThis paper deals with the human resource development and institutional capacity strengthening in Nigeria as they relate to policy analysis and research capacity in addressing the problems of poverty and food security. The findings of the paper show that there exist several human, physical, and institutional capacity gaps for designing and implementing agricultural policies in Nigeria.Non-PRIFPRI1; NSSPDSG
2012 Global food policy report: Overview [in Chinese]
No full textThis 2012 Global Food Policy Report is the second in an annual series that provides an in-depth look at major food policy developments and events. Initiated in response to resurgent interest in food security, the series offers a yearly overview of the food policy developments that have contributed to or hindered progress in food and nutrition security. It reviews what happened in food policy and why, examines key challenges and opportunities, shares new evidence and knowledge, and highlights emerging issues.Non-PRIFPRI1DGO; EPTD; MTID; DSGD; PHND; CO
