In Burkina Faso, the rainfall has been declining steadily for several years. Agriculture and livestock, which represent the main economic activities of the country, are obviously suffering the consequences, and it is estimated that 90% of the population are affected.
This problematic situation has no doubt caused the government of Burkina Faso to adjust the position it has held until early 2009: a ban on building water reservoirs to supply the dams.
Pursuing this new guideline, the municipal council of Tenkodogo (Boulgou province) is planning to build a water reservoir in the village of Ouéguédo (6 km from the town) for a downstream hydro-agricultural development project. After a geophysical survey which validated the concept, it was decided to provide a structure with a capacity of 30,975 cubic m.
