In its commitment to contribute to greater social well-being, to the development of economic opportunities and for the protection of the environment, the Ministry of Environment, Nature Protection and Sustainable Development wishes to study the possibilities of developing a project for the establishment of centralised biogas plant in the Abiergué watershed. It is in this perspective that the present work aimed to determine the most favorable areas for the development of the sector. In order to achieve this objective, the mapping coupled with the multi-criteria analysis was used as decision support tools to identify the most suitable site for the implementation of the unit. The results of the multi- criteria analysis indicate in order of preference the districts Mokolo, Cité verte, Oyomabang, Carrière and Nkolbisson, as the five most favorable areas for the installation of a centralised biogas plant, while districts Etetack, Nkolso’o and Melen, appeared to be the least favorable. The cartographic tool for its part, geolocalises the preferential areas around Oyomabang, Madagascar, Mokolo, Melen, Cité verte and Nkolbikok.
