People plant trees on the outskirts of Khartoum, Sudan, Jan. 12, 2017. Sudan's Khartoum State authorities on Thursday started planting around 1,000 trees as part of the state's greenbelt project, which is part of the African Great Green Wall. The African Great Green Wall project was endorsed by the community of Sahel-Saharan states (CEN-SAD) in 2005 and then it was approved by the African Union in 2007 as a strategic African project to help the African countries curb up the risk of desert creeping which threatens the CEN-SAD countries.
