| Declining soil fertility and recurrent drought pose serious challenges to farmers in Africas semi-arid regions, where half of all farmland suffers from erosion and nutrient depletion (Cleaver and Schreiber, 1997). In response, farmers and researchers across the continent have experimented with a broad array of soil and water conserving technologies (Reij et al., 1996). This paper describes the development and dissemination of one such technology from Zambia. |

| Non-timber forest products (NTFPs) play an important role in supporting rural livelihoods and food security in Zambia. NTFP-dependent households are poorer, have younger household heads with lower levels of education, and are located closer to district towns than other rural households are. NTFPs are a particularly important source of income in Luapula, Northwestern and Western provinces. • Income from woodfuel represented the greatest share of income for households that participated in NTFPs, and it was the most commonly reported business activity, with 68% of NTFP households reporting income from charcoal and firewood. NTFPs contribute an average of 32% to total household income among participants, with the poorest being more dependent on these sources.... |

| Market liberalization in Zambia has led to a rapid and fundamental transformation of its dairy sector. Mainly through foreign direct investment and international partnerships, a new formal dairy sector, characterized by institutional, organizational and technological innovation, emerged from the ashes of abandoned government projects. Sensing the development opportunity that arose from an untapped milk supply potential in Zambia's traditional smallholder livestock production and a growing milk demand from the newly emerging formal dairy processing sector, numerous donor-funded smallholder dairy farmer support programs emerged. At the same time, in order to protect its domestic market as well as to be in a better position to enter demanding export markets,... |

| The availability, access and affordability of food is a highly politicized issue throughout the world. In much of southern Africa, there is a widespread view that governments are responsible for ensuring that their populations have reliable access to food. Zambia, like most countries in Southern Africa, is vigorously pursuing continued direct public sector involvement and protectionist measures in the maize marketing sector. Since 1995, the Food Reserve Agency (FRA) and more recently, subsidies through the Fertilizer Support Program (FSP), have been the major instruments of government policy. While in some respects current operations undertaken by the government are similar to those adopted at independence, there are some noteworthy changes. Specifically,... |

| While theoretically more efficient than starch-based ethanol production systems, conversion of lignocellulosic biomass to ethanol is not without major challenges. A multi-region, multi-period, mixed integer mathematical programming model encompassing alternative feedstocks, feedstock production, delivery, and processing is developed. The model is used to identify key cost components and potential bottlenecks, and to reveal opportunities for reducing costs and prioritizing research. The research objective was to determine for specific regions in Oklahoma the most economical source of lignocellulosic biomass, timing of harvest and storage, inventory management, biorefinery size, and biorefinery location, as well as the breakeven price of ethanol, for a... |

| Natural resource use, including land, and rural population location is an important topic for Zambia's development strategy. Among other efforts, the Government of Zambia (GRZ) has designated 22% of total land area, as Game Management Areas (GMAs) for human settlements and wildlife conservation. Other GRZ programmes seek to improve food security and agricultural productivity, including the use and improvement of conservation farming techniques. GRZ is currently reviewing policies in the agricultural, forestry, fisheries, wildlife and land sectors. Research in these fields has much to contribute to effective management of MAs, increased agricultural productivity and improved welfare, especially for the rural population. |

| Forests support rural livelihoods and food security in many developing countries by providing critical sources of food, medicine, shelter, building materials, fuels, and cash income. The increasing demand for forest products has enhanced rural livelihoods and enabled the expansion of domestic markets, particularly in urban areas where woodfuel and other forest resources are scarce. Therefore, non-timber forest products may offer sources of income and opportunities for poverty alleviation in both rural and urban areas. In Zambia, most rural households residing near forests extract a range of forest products for both direct consumption and trade (including food products and wood for cooking fuel and charcoal production), and forest products are among the top... |
