Dust storms are a vital component of the environment. This book explores and summarises recent research on where dust storms originate, why dust storms are generated, where dust is transported and deposited, the nature of dust deposits and the changing frequency of dust storms over a range of time-scales. It is the first global study of causes and effects of dust storms, which are one of the increasing nature catastrophes.

Designed for advanced level secondary students, this geography text studies desertification, the encroachment of arable land by desert which threatens an estimated 35% of the Earth's land surface. It explains the causes of desertification, how it can be measured and combatted, and questions whether the situation is actually happening at the scale suggested. The author focuses on questions that have made desertification a major issue, and highlights the difficulties involved in dealing with such a broad-scale physical and social topic. Case study material and exercises are included in the text.
