Climate change has already been observed to have resulting impacts in many regions of the world, including rising sea levels, droughts, famine, increased natural disaster frequency, and expansion of Sahara desert-like conditions across Africa’s plains. 

The Sahara has been gradually contributing to the degradation of surrounding landscapes as global temperatures, and storms force its expansion into the Sahel region along the desert’s southern border. The Sahel region is home to more than 500 million people at a direct risk of diminishing habitable landscapes. Rising atmospheric temperatures, wind storms, and urban expansion are all to blame for the encroaching sands.

Unfortunately, as the Sahara expands southward, it is also consuming limited habitable lands, resources, and agricultural regions and subjugating its populations to increased hardships. Expert climatologists, environmentalists, and botanists gathered to develop and implement a plan to reverse the Sahara expansion and reclaim the land’s vital resources.  

The Great Green Wall Objectives

The Great Green Wall plan was originally launched in 2007 by the African Union. This enormous task involves the cooperation of 22 countries spanning more than 8,000 kilometers across the African continent. The project has been marketed as a living symbol of hope, striving to become the largest living structure on the planet by 2030. 

Foreign investments have also been involved in large aspects of the project relying on key partnerships between the African Union Commission, the Pan African Agency, and various international contributions. 

The project's overarching goals include restoring more than 100 million hectares of degraded land along the desert’s southern border. By restoring that region, the project will sequester approximately 250 million tons of carbon and create over 10 million green jobs in the Sahel region of impacted countries. 

Restore and acquire fertile land, one of Earth’s most valuable resources. 

• Generate economic opportunities for younger generations and support those already established in the urbanizing countries. 

• Provide food security for millions of people who are already facing struggles associated with food shortages, drought, and famine. 

• Establish climate resilience in the key Sahara/Sahel region, where climate change has already forced temperatures to rise faster than anywhere else on Earth 

• Create a new, natural world wonder that spans across the 8 000 kilometer region. 

With the finite plans in place and progress already well underway, many additional public campaigns have also aided fundraising efforts and overall contributions. The urgent initiative aims for a complete timeline of 2030 by instilling a global wide movement centering the Great Green Wall as a symbol of hope for impacted communities. 

The wall's completion by 2030 will have significant welfare impacts on global climate change, food security, and resource migration conflicts. Scientists hope the wall will become a lasting partnership of man and nature working together to provide resources and habitation for many generations. 

Planning The Great Green Wall

Installation for the Great Green Wall was originally planned to span from the Djibouti region in the east to Senegal in the west. The restoration area belt was expected to be approximately 15 kilometers wide, spanning the massive 8,000 kilometers across the Sahara’s southern border. 

Each of the involved countries has specific objectives attached to its section as it relates to their regional necessities. Using an integrated landscape approach has allowed local context to be applied to the wall’s development, addressing land degradation, climate change mitigations, biodiversity, and forestry efforts. Other goals slated by impacted counties include reducing erosion, creating green jobs, increasing crop yields, and improving the number of arable areas for agricultural development.
