Agriculture remains the most significant driver of global deforestation. Large-scale commercial agriculture and subsistence agriculture currently account for 73 percent of deforestation in the tropics and subtropics. However, it is possible under certain conditions to achieve sustainable agriculture and food security while also halting deforestation. A new study from FAO - The State of the World’s Forests 2016: Forests and agriculture - land use challenges and opportunities - identifies more than 20 countries that have maintained or increased forest area, and improved food security since 1990. This video focuses on successful methods in Costa Rica, Viet Nam and The Gambia.
