  abstract = {{L}ivestock-driven nutrient flows are the main sources of soil and crop fertilization in {W}est {A}frican agro-sylvo-pastoral landscapes. {T}hey result from nutrient recycling between farm activities and the spatial transfer of nutrients within the landscape. "{E}xtensive" systems, based on livestock mobility are tending to be replaced by more "intensive" systems based on in-barn livestock fattening. {W}e built an agent-based model to compare these systems in terms of nitrogen cycling at land plot, herd, household and village levels. {M}odel evaluation, based on field-data from two real contrasted villages, showed that the model satisfactorily reproduces the differences between an "extensive" and an "intensive" system with key parameters such as variability among households and soil fertility gradients. {S}imulations highlighted bottlenecks along the nitrogen ({N}) cycle like accumulation of {N} in manure heaps and housing areas, reducing {N} recycling efficiency, especially in "intensive" systems. {T}he model can be further used to explore improved agro-sylvo-pastoral landscapes.},
