Yahya's nomadic family has been forced off their land on the fringes of the Sahara, because of desertification. Through his story, this title considers the impacts of desertification and its causes, including: climate change, population pressure, over abstraction of water, overgrazing and salinisation. It then considers a range of responses including tree planting, the use of appropriate technology and the introduction of sustainable water and soil management strategies.
