The Great Green Wall was launched in 2007 by African Union to overcome desertification.


  • It is an African-led initiative aiming to restore Africa’s degraded landscapes and transform millions of lives in one of the world’s poorest regions, the Sahel.
  •  Once complete, the Wall will be the largest living structure on the planet – an 8,000 km natural wonder of the world stretching across the entire width of the continent.
  • The Great Green Wall is now being implemented in more than 20 countries across Africa and more than eight billion dollars have been mobilized and pledged for its support.
  • The initiative brings together African countries and international partners, under the leadership of the African Union Commission and Pan-African Agency of the Great Green Wall.


  • To restore 100 million ha of currently degraded land by 2030.
  • To sequester 250 million tons of carbon and create 10 million green jobs.
  •  This will support communities living along the Wall .
  • Grow fertile land, one of humanity’s most precious natural assets
  • Grow economic opportunities for the world’s youngest population
  • Grow food security for the millions that go hungry every day
  • Grow climate resilience in a region where temperatures are rising faster than anywhere else on Earth
  • Grow a new world wonder spanning 8000 km across Africa
