摘要：Human dejections and agro-pastoral residues biogas potentials of the Comoé river catchment (CRC) were evaluated using agricultural and population statistics, and the indices of residues biogas productivity. The CRC contains an annual biogas volume of 318x106m3. This energy resource is by far higher than the energy needs of rural population in Côte d'Ivoire. But this resource is unequally distributed in the CRC localities. Ferkessédougou department contains the maximum potential (172.7x106m3) of biogas. The agricultural residues among the others wastes contained the highest biogas potential (124.8x106m3). The complexity of biogas production from agricultural solid organic residues makes these substrates inappropriate to household exploitation. In the other hand, centralized unit can be installed in Ferkessédougou and Abengourou to produce biogas from these residues in the aforementioned localities. Small decentralized units could be established in the localities containing livestock waste. Biogas production using agropastoral organics residues must be preceded by sensitizing of populations, in order to reduce their traditional utilisation habit and to fight against taboos.
