Agroforestry, that is the cultivation of trees together with crops can help farmers cope with several of the adverse consequences of climate change. The world Agroforestry Center (ICRAF) has assessed the potential for Agroforestry to help adapt to climate change. Researchers have found that planting trees between crops and in the boundaries around crops can help prevent soil erosion, restore soil fertility, and provide shade for other crops.
Agroforestry also has the benefits of contributing to climate change mitigation, because trees and shrubs tend to sequester more carbon than other crops.
