PLANNING STUDY OF A HYDROELECTRIC POWER PLANT IN LOWER MANDRARE: CASE OF AMBOETSY

Géosciences

The Deep Southern of Madagascar possesses potential natural resources that could be beneficial to the local population. This area is highly rich and has various potentials, making it a zone of excellence for the future. However, the relevance of the vulnerability of the population's livelihood is strongly felt. It is an undeniable strategy that needs to be thoroughly studied for a sound local development project. Nevertheless, the fundamental constraint for socio-economic development in this area is the insufficient water resources. Given the interdependence of various production factors, implementing a single development project does not solve the problems. Therefore, it is essential to establish and implement a multi-component project, including provisions for drinking water supply, agriculture, livestock, hydroelectric power production, etc. Thus, the key factor for the development of the South lies in mastering water resources, regardless of the proposed options. This article focuses on studying an inter-hill type dam at sites with multiple development possibilities, including drinking water supply, irrigation, and hydroelectricity. The development of the Amboetsy hydroelectric power plant in the lower Mandrare was undertaken to harness the hydroelectric energy of the Mandrare River. The construction involved creating a reservoir, a power plant, and related infrastructure. The objective was to provide electricity to the surrounding regions, especially urban areas and industrial installations. However, this has led to environmental and social impacts, such as reduced river flow and population displacement.
