| A number of technology transfer (diffusion) programmes involving amongst others veterinary surgeon services subsidised by the government, were launched in the former homelands of South Africa between 1980 and 1993. Many of these programmes were discontinued after the general election of 1994. In order to evaluate the adoption of technology in Qwaqwa, a former Sotho speaking homeland, two Logit models were fit using the conventional definition of an adopter and an adapted definition, which included potential adopters with the adopters. Where the conventional definition of adoption was estimated, livestock income per LSU, ram technology, roads and suppliers of livestock inputs are significant variables contributing to adoption. The results of the adapted... |

| New technology introduction in this semiarid region of the Sahel is hypothesized to be made more difficult by three price problems in the region. First, staple prices collapse annually at harvest. Secondly, there is a between year price collapse in good and very good years due to the inelastic demand for the principal staple, millet, and the large changes in supply from weather and other stochastic factors. Thirdly, government and NGOs intervene in adverse rainfall years to drive down the price increases. Marketing strategies were proposed for the first two price problems and a public policy change for the third. To analyze this question at the firm level a farm programming model was constructed. Based upon surveying in four countries, including Niger,... |

| Cotton has been a success story in West Africa since independence swept the region in the early 1960's. Today, however, 'white gold' is struggling to maintain its allure. Recent declines in world cotton markets have created a crisis in the region's cotton sectors. Cotton is still being produced within an institutional structure that dates back to the independence era of the early 1960's. The new era of volatile cotton markets, new technological frontiers, and global challenges are placing demands on institutional change. This paper uses an economic model of the agricultural sector to predict the impacts of cotton liberalization. Shifting control from the state into the hands of the private sector would provide significant benefits to society. Farmers in... |

| In Niger as in most of semiarid Sub-Saharan Africa the fallow system has become a historic event as a result of increasing population pressure and has not yet been replaced with increased input use due to low product prices. As a result nutrient mining is becoming prevalent and cereals yields declining. So it is necessary to develop marketing and other strategies to increase farmers' incomes from the use of increased inputs for soil fertility especially inorganic fertilizers. In the farm model, two goals (subsistence food storage and harvest income) are first achieved, before maximizing income, in a linear programming framework with various states of nature. This is an alternative way of handling risk based on farmer's actual observed behavior. Hence this... |
