The Great Green Wall (GGW) is a strip of multi-specie Vegetation linking Dakar to Djibouti over a
length of 7000 km with a width of 15 km, linear and continuous as much as possible. However, due to some factors, the course may divert, move northwards or descend southwards. These factors areamong others:
• water courses : rivers, lakes,
• mountains or rocky hills,
• flat but rocky terrain impossible to revitalize,
• marshy areas,
• urban settlements,
• areas the local populations consider haunted or sacred.
The strip should necessarily be located within the Sahel zone with averages rainfall between
100 to 400 mm.
It integrates several systems of land use such as:
- natural farms: reserved forests (managed by the State), community forests
(Villages, municipalities, rural communities etc.), private forests (belonging to individuals or
private groups);
- old artificial farms (results of the zone's projects) or new ones (to be established;
- agro-forestry units: annual orcharding , wooded hydro-Agricultural areas, pares des terroirs ;
- grazing zones: village or community;
- Animal parks;
- community wildlife areas:
- national parks: entirely or in part ;
- botanical reserves: for the conservation of plant biodiversity;
- deferred grazing: at the level of more or less degraded forest areas
- orchards: fruit farms.
