The Global Desertification Challenge

Made with the help of NGO Practical Action, this film explains why more and more farmers are being forced off their land on the fringes of the Sahara. Through their stories, it considers the impacts of desertification and its causes, including: climate change, population pressure, over abstraction of water, overgrazing and salinisation. It then explores a range of ways people are responding to slow the spread of deserts, including tree planting, the use of appropriate technology and the introduction of sustainable water and soil management strategies.
