CONTRIBUTION DE LA TECHNOLOGIE DU BIODIGESTEUR A LA DURABILITE DES EXPLOITATIONS AGRICOLES FAMILIALES AU BURKINA FASO

Abstract

Despite problems related to energy, biomass reduction, grazing degradation, decreased soil fertility, environmental fragility, the biodigester is positioned as a strategy of adaptation and transformation of production systems with the association of agriculture and livestock. The biodigester is an underground construction that uses cow dung or pork excrement mixed with water to produce biogas for cooking and lighting and effluent compost for soil fertilization. The study aimed to evaluate the contribution of the Biodigester technology to agro-ecological sustainability, socio-territorial sustainability and socio-economic sustainability. The study was undertaken in November 2015 in the municipalities of Bobo Dioulasso, Kaya-Barsalgo and Dori. The individual survey was conducted in twenty-four (24) villages on a sample of 166 heads of farms. The results showed the contribution of biodigester technology to agro-ecological, socio-territorial and socio-economic sustainability. Furthermore, land security, the cost of installing the infrastructure, insufficiency or scarcity of cow dung at certain times of the year, lack of water remain the main limits of adoption of the Biodigester technology. The biodigester is an appropriate technology capable of solving the economic, agricultural and energy questions faced by households.
