Water resources implications of integrating malaria control into the operation of an Ethiopian dam por Reis, J., Culver, T.B., McCartney, Matthew P., Lautze, Jonathan F., Kibret, S.

“…This paper investigates the water resources implications of using a method of hydrological control to reduce malaria around the Koka reservoir in central Ethiopia. This method is based on recent ndings that malaria is transmitted from the shoreline of the Koka reservoir, and on a similar method that was used to control malaria some 80 yr ago in the United States. …”

Description of potential development domains for Humidtropics—A CGIAR Research Program por Steeg, Jeannette van de

“…Empirical studies in Ethiopia, Kenya and Uganda (e.g. Pender et al. 1999; Pender et al. 2004; Ehui and Pender 2005) suggest that interaction of the three socio-economic and biophysical layers—population density, agricultural potential and market access—provide good explanatory power in predicting the type of agricultural enterprises and development pathways encountered in different rural communities, as the layers are strongly related to the feasibility and attractiveness of specific development and livelihood strategies (Wood et al. 1999). …”
