Deforestation of tropical forests for the establishment of grass monoculture for livestock production is responsible for about 30 % of CO2 emissions. This issue is particularly severe in degraded pastures because degraded soils favor CO2 flow to the soil surface. Silvopastoral systems could reduce CO2 emissions, notably by using live fences. Here,...
