Progress is slow on Africa’s Great Green Wall, but some bright spots bloom

 
Africa’s ambitious Great Green Wall, a mosaic of reforestation efforts to stop desertification, has been plagued by delays and challenges.Some reforestation efforts, however, have tasted success, becoming a model for many to follow.Experts suggest moving away from viewing the initiative as merely a tree-planting exercise and instead seeing it as a holistic, participatory approach that involves local communities and helps them build their livelihoods and incomes.Challenges still abound, however, including a volatile security situation, lack of water, coordination challenges, and scattered long-term monitoring of reforested patches.

The southern fringes of the Sahara are dynamic. As rainfall varies, land patches on the edge chop and change between green and arid brown. Human activities, like overgrazing, deforestation or poor irrigation, further degrade some of the already arid parts of the Sahel, resulting in desertification. As the planet heats up, changes in rainfall patterns can cause longer dry spells on the southern boundaries of the Sahara, stretching the desert further down, and affecting nearly a million people and their livelihoods in the Sahel.
