As of March 2019, 15 per cent of the wall is complete with significant gains made in Nigeria, Senegal and Ethiopia.[21] In Senegal, over 11 million trees had been planted. Nigeria has restored 4.9 million ha (12 million acres; 49,000 km2) of degraded land and Ethiopia has reclaimed 15 million ha (37 million acres; 150,000 km2).[2] In September 2020, it was reported that the Great Green Wall had only covered 4% of the planned area, with only 4m hectares (9.8 million acres) planted. Ethiopia has had the most success with 5.5bn seedlings planted, but Chad has only planted 1.1m.
