We teach a technique of agroforestry called Inga Alley Cropping to small farmers and indigenous groups in the Ecuadorian Amazon, and village communities in Cameroon in the Congo Basin. This gives them an alternative to cutting and burning small patches of forest for new fields and enables them to grow high-nutrient, chemical-free crops inside the Inga alleys with yields often 10-15 times more than outside the alleys. The system reduces carbon emissions from forest loss, and sequesters carbon in the soil and trees, while restoring the soil, combating poverty, and protecting places with high biodiversity.
