The impact of the CFA devaluation on cereal markets in selected CMA/WCA member countries by Badiane, Ousmane

“…The assessment of the impact of the devaluation of the CFA Franc in early 1994 on the cereal sector starts with the analysis of the historical relationships between cereal prices and the exchange rate in selected West Africa countries. In addition, a model examining the transmission of the changes in the value of the CFA franc to producer prices is developed and estimated, in order to gain more insight on the role of different factors in determining the level of transmission. …”

Justice in development?: an analysis of water interventions in the rural south by Venot, Jean-Philippe, Clement, Floriane

“…Specifically, we document the planning and implementation of two types of water interventions in two contrasting regions: watershed development programmes in northeast India and small reservoirs in sub-Saharan West Africa.We find that there is a contradiction between the inherently political nature of water interventions and the fact that such projects remain grounded in apolitical, technical and managerial narratives. …”

Environmental impacts of trypanosomiasis control through land-use change: Conceptual model, approach and preliminary results by Reid, Robin S., Kruska, Russell L., Ellis, J.E., Wilson, C.J., Perry, Brian D.

“…Preliminary analyses provide support for the hypothesis that trypanosomiasis is retarding the large-scale correlations show that there is no simple inverse relationship between the presence of tsetse and the presence of agricultural land-use and that tsetse appears to limit agricultural land-use more strongly in southern than in West Africa. These results imply that decisions concerning where and when to control trypanosomiasis can have strong implications for the success of efforts to enhance human welfare and to maintain environmental quality.…”
