This theme stresses the idea that arid or semi-arid environments are not always remote areas of hazard and hardship. These environments should be seen as a setting for human activity and the range of opportunities and challenges they present should be understood. The theme covers the location of hot, arid environments; the geomorphic processes that operate in them; the landforms which result; and the climate, vegetation and soils of these areas. Central to this theme are the issues that arise from the interaction of people with the arid environment such as desertification, salinization, land-use conflicts and water management. Case studies should be used where appropriate.
