An inspirational project for our times, the Great Green Wall is an African-led initiative to establish an 8000 km wall of trees spanning the width of the continent at the southern edge of the Sahara Desert. The aim is to revitalize ecosystems and restore economies in order to provide food security, jobs and a reason for millions to stay in the region. After a decade, the wall is about 15% ‘built’ and, once completed, will be the largest living structure on the planet, 3 times the size of the Great Barrier Reef. The film focuses on Malian musician/activist Inna Modja as she journeys from Senegal to Djibouti gathering stories and sharing songs with people living along the Great Green Wall.
