  abstract = {{S}oil fertility degradation is a major stake in sub-{S}aharan {A}frica. {S}trong population growth, local demand for food and land scarcity are likely to increase this phenomenon. {W}hile mineral fertilizers are little used, particularly in {M}adagascar, soil fertility management is therefore largely dependent on organic fertilizers produced on the farm. {I}n 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. {T}his study proposes to analyze the relationships between the structure of farms integrating crop and livestock in the {V}akinankaratra region ({H}ighlands of {M}adagascar) and their manure management practices. {S}emi-structured interviews were carried out on 300 farms. {T}hen, a farm typology was built through a {P}rincipal {C}omponent {A}nalysis ({PCA}). {S}even farm types were identified, distinguishing dairy farms from other agri-livestock farms (zebus, pigs). {A} {C}hi(2) test indicates a significant effect of farm structure on effluent management methods. {I}n particular, the presence of dairy and pig farming within farms seems to favor improved manure management. {T}he cluster analysis contributes to understanding the adoption of improved biomass management practices by crop-livestock farming systems. {T}he 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 {V}akinankaratra {H}ighlands.},
