Africa Builds ‘Great Green Wall’ of Trees to Improve Farmlands
31st December 2014
To mitigate this and other environmental issues affecting Africa such as land degradation, the effects of climate change, and a loss of biodiversity, Senegal is leading a 20-nation initiative known as the Great Green Wall. Most notably, this initiative involves erecting a wall of trees across the southern edge of the Sahara desert, which will be 14 km wide and 7,600 km long. When completed, it will be the largest horticultural feature in history. The initiative will also focus on establishing sustainable farming and livestock cultivation, and improving food security.
