This book was released on 2003-01-01 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Action is needed to fight poverty by sustaining the environment and the use of natural resources. Land Quality, Agricultural Productivity, and Food Security explores a range of factors driving food security. The book offers an assessment to link quality of the available land resources with productivity of land and the ability to ensure food security. It offers a mixture of broad-scale assessments across the globe, with detailed case studies, deepening our understanding of economics and decision-making mechanisms. It is recommended to researchers, as well as actors in the private and public domain, who are keen to improve their understanding of the appropriate actions that ensure food security in the decade to come.' - Floor Brouwer, Agricultural Economics Research Institute (LEI), The Hague, The Netherlands Land quality and land degradation affect agricultural productivity and food security, but quantifying these relationships has been difficult. Data are extremely limited and outcomes are sensitive to the choices that farmers make. The contributors to this book - including soil scientists, geographers, and economists - analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: * the extent to which differences in land quality generate differences in agricultural productivity across countries * how farmers' responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and * whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.

This book was released on 2005 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture plays a crucial role in the economy of sub-Saharan Africa. A feature of particular significance about the region is that the majority of households are heavily dependent on agriculture as their major source of livelihood. Smallholder agriculture is the principal producer of staple foods and cash crops, accounting for very large shares of national production and marketed output. For the respective countries, therefore, the performance of smallholder agriculture has crucial implications for the overall economic development process including the alleviation of rural poverty. The demands created by steadily increasing populations, and the pressing need to increase agricultural productivity means that these countries must continuously adopt methods to intensify agricultural production. Livestock production is an important consideration in the agricultural development of the region. Livestock, and especially cattle, have historically played multiple roles both in economic life and in socio-cultural traditions of African people. Cattle have been valued not simply as a source of food (milk, blood and meat) and hide but also as a visible form of wealth and a source of social prestige. In certain parts of the region, cattle still provide a valuable source of draft and traction power both for the plough and for transportation carts whereas in Arid and semi-arid lands (ASAL), cattle still provide a valuable security against famine. Traditionally, cattle were a valuable item in the payment of bride price while beef was a valued food item in ceremonies. Moreover, cattle manure is still valued as a fire-fuel and building material in ASAL whilst in arable areas it is valued as a fertilizer. In brief, cattle have retained their multiple roles among the African people. The relative importance of each role, however, varies with production and ecosystems (Freeland 1998; Fitzhugh 1998). In the high potential areas, the economic importance of the cow has increasingly shifted to commercial milk production while at the same time retaining the complementary role of sustaining soil fertility for sustainable agricultural production. In such area, increasing population pressure interacting with the need to sustain soil fertility has driven the change in production structure with dairying becoming an important component of agricultural production. Eastern Africa is Africa's most promising region for dairy production. The region is predominantly rural, with over 80 per cent of its inhabitants deriving its livelihood heavily from agriculture. It holds over 40 percent of Africa's cattle resource of about 222 million (FAOSTAT). This study looks at the development of dairy industry in two east African countries - Kenya and Uganda (Figure 1). From the early 1910s, Kenya has developed a dairy industry that ranks among the largest in sub-Saharan Africa. The industry is especially noted for its smallholder base. Uganda, on the other hand, has a large unexploited potential for dairying. In order to highlight special aspects of the respective country's industry, the study looks at the countries in turns. The study seeks to take a historical look at the respective dairy industries with a view to identifying major turning points in their respective developments. We then apply the DE-A-R framework in analyzing the circumstances surrounding respective turning points, including the socio-political forces that influenced the specific forms of change. Our purpose is to identify the forces, and key actors, that have driven changes in the systems, and to understand the impact these changes have had on the overall production, on smallholder incomes and on the environment by comparing across countries. We hope to identify key ingredients necessary for achieving successful smallholder dairy growth elsewhere.

Download or read book Participation of Local People in Water Management Evidence from the Mae Sa Watershed Northern Thailand written by Helene Heyd and Andreas Neef and published by Intl Food Policy Res Inst. This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1990s, Thailand launched an ambitious program of decentralized governance, conferring greater responsibilities upon sub-district administrations and providing fiscal opportunities for local development planning. This process was reinforced by Thailand's new Constitution of 1997, which explicitly assures individuals, communities and local authorities the right to participate in the management of natural resources. Drawing on a study of water management in the Mae Sa watershed, northern Thailand, this study analyzes to what extent the constitutional right for participation has been put into practice. To this end, a stakeholder analysis was conducted in the watershed, with a focus on the local people's interests and strategies in water management and the transformation of participatory policies through government agencies at the local level. Government line departments were categorized into development- and conservation-oriented agencies. While government officers stressed the importance of stakeholder inclusion and cooperation with the local people, there is a sharp contrast between the official rhetoric and the reality on the ground. The analysis reveals that government officers, particularly in the conservation-oriented agencies, are not disposed to devolve power to lower levels due to the fear of losing their traditional mandate and persistent stereotypes about local communities' incompetence to manage water resources in a sustainable way. On their part, villagers do not perceive a tangible change in the implementation of water policies and retain a widely negative image of government officers. In conclusion, the participation of local people in development activities and in the conservation and management of natural resources seems to be currently at the stage of passive or, at best, consultative participation. In order to deal with the severely increasing water problems in northern Thailand, decision-makers have to recognize the value of participation and promote a change of government officers' attitude towards local people through training programs and incentives. Communities and individuals need to be made aware of their constitutional rights and potentials for cooperating with government agencies and participating in their projects.

Download or read book Assessing the Spatial Distribution of Crop Production Using a Cross Entropy Method written by Liangzhi You and Stanley Wood and published by Intl Food Policy Res Inst. This book was released on 2012 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: While agricultural production statistics are reported on a geopolitical - often national - basis we often need to know the status of production or productivity within specific sub-regions, watersheds, or agro-ecological zones. Such re-aggregations are typically made using expert judgments or simple area-weighting rules. We describe a new, entropy-based approach to making spatially disaggregated assessments of the distribution of crop production. Using this approach tabular crop production statistics are blended judiciously with an array of other secondary data to assess the production of specific crops within individual "pixels" - typically 25 to 100 square kilometers in size. The information utilized includes crop production statistics, farming system characteristics, satellite-derived land cover data, biophysical crop suitability assessments, and population density. An application is presented in which Brazilian state level production statistics are used to generate pixel level crop production data for eight crops. To validate the spatial allocation we aggregated the pixel estimates to obtain synthetic estimates of municipio level production in Brazil, and compared those estimates with actual municipio statistics. The approach produced extremely promising results. We then examined the robustness of these results compared to short-cut approaches to spatializing crop production statistics and showed that, while computationally intensive, the cross-entropy method does provide more reliable estimates of crop production patterns.
