standard How to green the world’s deserts and reverse climate change

Desertification is not only a problem for the countries that experience it, but for the entire planet.  In this talk given by Allan Savory on TED, he explains how managing grasslands ‘holistically’ can reduce desertification, namely ‘by keeping cattle more densely packed on small plots of land and moving them frequently‘.  This keeps herds from overgrazing and fertilises the land at the same time, restoring its nutrients.  And if you can prevent grasslands from turning into desert they can remove carbon dioxide from the air, helping to mitigate carbon emissions that cause climate change.  Simple, yet effective and cattle grazing, often viewed as ecologically destructive, becomes an environmental solution, not a problem.  It also seems a great way to assist pastoralist communities in Africa.
