Stage 5 Sustainable Biomes

This “Green Wall” was originally supposed to span the southern border of the Sahara from the east to west coast of Africa. It was made up of trees and elements of forests in order to prevent the desert from expanding and reducing the amount of land available for food production. This seems like it would be a great idea that would work well, but the plan has some flaws. In the early stages of building up the barrier, nomadic herders are supposed to be prohibited from using the land, as their cattle would destroy it. However, the system in place in Somolia sees only one soldier guarding hundreds of kilometers by himself. The nomadic people are often desperate for food, so they often try to break in and sometimes resort to violence. This is problematic because it defeats the purpose of the barrier in increasing the farm land. Many of the countries in along the “Green Wall” do not maintain it as well as they should and Nigeria actually abandoned the project all together. For this reason many ecologists believe the effort is a waste and the climate change can not be stopped. But the efforts of the Somalians has paid off. Crops such as grapefruit and watermelon have been grown in areas that would have been unsuitable for such crops a few years ago. Migratory European birds also settle in the area during the winter. Another benefit that comes from the Wall is that nomads are not forced to join terrorist organizations as their only sources for food, because farming is made easier in the Sahel. 

The great green wall is a man made ecological wall from the Atlantic ocean thru 10 countries to the red sea.  This is to prevent the desert from expanding, but also it is protected from nomadic herders, and loss of food.  This project still has a long way to go but ha not been completely abandoned yet. 

Although Senegal is one of the few countries in the Sahel to actually follow through on its promise of building its green wall, it may be fruitless in the long run. The expansion of desert regions seems relentless. However, what is most surprising is how rapidly the ecosystems have changed and the crops that can be grown there. Watermelon, grapefruit, and European migratory songbirds have all taken hold, drastically altering the agriculture and environment of the region.
