🎧 Great Green Walls – holding back the deserts

Listened Great Green Walls – holding back the deserts from Radio National

Desertification and land degradation affect the lives of around three billion people, according to UN estimates.

24 billion tonnes of fertile soil are lost to land degradation every year.

We look at two ambitious projects aimed at halting desertification and returning soil to productivity. They are: the Great Green Wall project in northern Africa; and the Green Great Wall initiative in China.

Antony Funnell discusses the attempts on two continents to hold back the spread of deserts. What is interesting is that just as the creep of the desert is not a given, simply ‘planting trees’ will not resolve the situation. This made me wonder again about permaculture.
