Sommario/riassunto

Taking a global perspective, this book provides a concise overview of drylands, including their physical, biological, temporal, and human components. Examines the physical systems occurring in desert environments, including climate, hydrology, past and present lakes, weathering, hillslopes, geomorphic surfaces, water as a geomorphic agent, and aeolian processes Offers an accessible introduction to the physical, biological, temporal, and human components of drylands Investigates the nature, environmental requirements, and essential geomorphic roles of plants and
