The Great Green Wall

Sahel-Sahara project aims to combat land degradation

By Ryan Schleeter
In Africa, scientists are hard at work restoring land once rich with biodiversity and vegetation. Eleven countries in the Sahel-Sahara region—Djibouti, Eritrea, Ethiopia, Sudan, Chad, Niger, Nigeria, Mali, Burkina Faso, Mauritania, and Senegal—have joined to combat land degradation and restore native plant life to the landscape.
In recent years, northern Africa has seen the quality ofarable land decline significantly due to climate change and poor land management. Uniting under the banner of the “Great Green Wall” initiative, national and regional leaders hope to reverse this trend. The bulk of the work on the ground was originally slated to be concentrated along a stretch of land from Djibouti, Djibouti, in the east to Dakar, Senegal, in the west—an expanse 15 kilometers (9 miles) wide and 7,775 kilometers (4,831 miles) long. The project has since expanded to include countries in both northern and western Africa.
Land degradation typically stems from both human-related and natural factors; overfarming, overgrazing, climate change, and extreme weather are the most common causes. Beyond affecting land and the natural environment, land degradation poses serious threats to agricultural productivity, food security, and quality of life. Nowhere is this issue more urgent than in sub-Saharan Africa, where an estimated 500 million people live on land undergoing desertification, the most extreme form of land degradation.
Jean-Marc Sinnassamy is a senior environmental specialist with the Global Environment Facility (GEF). He helps manage a program developed under the Great Green Wall initiative with countries in the Sahel and West Africa. The GEF has been with the initiative since the beginning, helping to convene country leaders at the headquarters of the United Nations Convention to Combat Desertification in Bonn, Germany, in February 2011. The World Bank and other organizations focused on global development and the environment provide financial and technical support.
For Sinnassamy, the partnership represents a unique opportunity to work across the region with a solid political base.
