Soil fertility degradation is a major stake in sub-Saharan Africa. Strong population growth, local demand for food and land scarcity are likely to increase this phenomenon. While mineral fertilizers are little used, particularly in Madagascar, soil fertility management is therefore largely dependent on organic fertilizers produced on the farm. In order to increase the efficiency of nutrient recycling at farm level, it is necessary to understand the factors that contribute to improved manure management practices. This study proposes to analyze the relationships between the structure of farms integrating crop and livestock in the Vakinankaratra region (Highlands of Madagascar) and their manure management practices. Semi-structured interviews were carried out on 300 farms. Then, a farm typology was built through a Principal Component Analysis (PCA). Seven farm types were identified, distinguishing dairy farms from other agri-livestock farms (zebus, pigs). A Chi(2) test indicates a significant effect of farm structure on effluent management methods. In particular, the presence of dairy and pig farming within farms seems to favor improved manure management. The cluster analysis contributes to understanding the adoption of improved biomass management practices by crop-livestock farming systems. The adoption of such practices is a prerequisite for improving nutrients recycling from animals to agricultural plots, and thus improving the sustainability of farms in the Vakinankaratra Highlands.
