Various donors and funds promised to make donations to support the pan-African Great Green African Wall (GGW) against the desert. This became clear during a meeting of the UN Convention to Combat Desertification (UNCCD) in the last week of February. In sum, these donations could mount up to around 3 billion US dollars. The envisaged 15 kilometers wide and up to 8000 kilometers long wall consisting of plants and trees will cross 11 countries south of the Sahara. The difference between failure and success will depend on the way the project is executed.
