EverGreen Agriculture provides economic benefits but faces challenges scaling up. Studies show: 1) Tree products in Sahel countries are worth $100-300/household annually. Mango exports increased 100% in Kenya. 2) Doubling mature fertilizer trees in Niger/Mali could increase millet yields by 200,000-300,000 kg on 10,000 ha. 3) Challenges include restrictive forest laws, grazing/fires, poor markets, and lack of adapted germplasm and knowledge about integrating trees.
