As the fight against climate change intensifies, a farming practice called agroforestry has the potential to improve food security while increasing resilience to global warming. Agroforestry is the integration of trees and shrubs with crops and livestock systems, and when done correctly, it can boost field crop yields, diversify income, and store carbon in the earth to mitigate climate change. One reason is agroforestry is so effective is due to the nitrogen-rich leaves that fall from trees during the rainy season. These leaves fall to the soil, and fertilize crops naturally at a useful time without competing for light, nutrients or water. Now backed by a body of research, agroforestry has become a centerpiece to FAO’s sustainable farming guide and will especially important for developing countries where resources are less plentiful.
