Andrew Millison — Restoring Global Ecology: The Great Green Wall and Large-Scale Permaculture in Action

The Great Simplification
Description
It’s no secret that massive change is needed to restore our planet’s vital ecosystems. Permaculture offers practices to restore local environments by focusing on creating sustainable agricultural systems that mimic patterns found in nature. But how might permaculture initiatives go beyond agriculture to transform some of our largest-scale problems, such as social cohesion, climate stabilization, and even human migration?
In this conversation, Nate sits down with permaculture educator Andrew Millison to discuss the Great Green Wall project, a massive ecological initiative aimed at combating desertification in the Sahel region of Africa. They explore the causes of the Sahara Desert’s expansion, the simple but impactful permaculture techniques being employed to restore land, and the significant ecological and nutritional benefits resulting from these efforts. This conversation highlights the collaboration between local communities and global organizations, emphasizing permaculture’s potential to transform lives and ecosystems around the world.
How can innovative permaculture techniques aid in helping our most complex ecological challenges? In what ways have land restoration projects reduced conflict between people in resource scarce areas? Furthermore, what kinds of responses – both grassroots and top-down – are needed to implement these practices on a large scale?

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor
