Environmental Impact Assessment of Settlement and Development in the Upper Léraba Basin


Texte intégral

1The Upper Léraba pilot study was commissioned by the Committee of Sponsoring Agencies (CSA) of the Onchocerciasis Control Programme in West Africa (OCP), and jointly funded by the Government of The Netherlands and The World Bank. The original design for the study was formulated in January 1992 by the Ecological Group (EG) of the OCP’s Expert Advisory Committee (EAC), in response to a request from the CSA. After internal review and reformatting into a plan of action, the proposal was submitted by the CSA to the OCP Joint Programme Committee (OCP 1992), which endorsed it during its thirteenth session (Geneva, December 1992).

2In January 1993, the plan of action for the pilot study was revised to reduce its geographical scope (in its original form the plan made provision for a parallel study in Côte d’Ivoire), and implemented by a team of three senior biological scientists; Dr. David Baldry, formerly a biologist with WHO and FAO, Professor Davide Calamari, Professor of Applied Ecology, Institute of Agricultural Entomology, University of Milan, and Dr. Laurent Yaméogo, OCP Hydrobiologist.

3Aerial photographic surveys and fact-finding missions in the OCP area could not have been conducted so effectively without the support of Dr. Ebrahim M. Samba, former OCP Programme Director, and his staff, who placed their facilities at the disposal of the study team while its members were in West Africa, and who provided important archival information on the Upper Léraba Basin.

4Likewise, it would have been much more difficult for the study team to accurately assess agrochemical impacts without the collaboration of officials of the Government of Burkina Faso, who kindly provided climatic, hydrological and agricultural data on the Upper Léraba Basin.

5The members of the study team would also like to express special thanks to Mr. Manuel Bravo, pilot of Evergreen Helicopters, Inc., for safe aerial operations in the OCP area, and to Mr. Bruce Benton, Dr. John Elder and Dr. Bernhard Liese, The World Bank, for their unstinting support and encouragement during the implementation of the Pilot Project.
