Tropical and subtropical regions have the largest potential area and climatic conditions for sus-tainably hosting silvopastoral systems focused on the production of wood and livestock in at least two “pro-duction modes”. These regions concentrate extensive areas with pastures, in which there is a great oppor-tunity to match forestry production to the profile of regional production rather than competing for land use. This can be beneficial for both productive sec-tors since certification standards for both forestry and livestock encompass a wide range of economic, social, environmental, and technical management aspects, including people’s well-being and liveli-hoods. It could converge objectives for both busi-nesses toward a central element and disruptive of an innovative bio-based economy. The “wood model” focuses on producing a greater volume of wood bio-mass. It requires a high tree-stocking rate (33–47%) into pastures. The “cattle model” integrates more pas-ture production with fewer trees (< 33% tree-stocking rate). This model requires larger spaces between trees to allow for thicker logs (sawn wood). Both models protect herds and forage. In the “wood model”, nega-tive interactions occur with still young trees. Spacing between strips generates alleys; alleys need to have a width between 3.5 and 5 times the tree canopy depth. Wide alleys facilitate herding; cattle perceive alleys as open spaces without being spooked by the cowboy approximation. Parallel strips facilitate silvicultural and harvest tree operations, animal herding, uniform-ity of tree density, minimization of runoff surface, and soil erosion.
