The Great Green Wall of Africa

  • The world’s most ambitious reforestation project, the Great Green Wall of Africa, has covered only 4% of its target area but is more than halfway towards its 2030 completion date.
  • More funds, greater technical support and tighter oversight will be needed if the plan to plant 100m hectares of trees and other vegetation is to be realised.
  • The Great Green Wall was conceived in 2007 by the African Union as a 7,000km (4,350-mile) cross-continental barrier stretching from Senegal to Djibouti that would hold back the deserts of the Sahara and Sahel.
  • It would improve livelihoods in one of the world’s poorest regions, capture carbon dioxide and reduce conflict, terrorism and migration.
  • Ethiopia, which started reforesting earlier than other nations in the region, is a frontrunner, having reportedly planted 5.5bn seedlings on 151,000 hectares of new forest and 792,000 of new terraces.
  • A major problem is monitoring. Individual nations provide their own estimates, but there are doubts as to how many of the 12m trees planted in Senegal, for example, have survived.
