Global climatic change will most likely affect natural resources and human living conditions in semiarid regions. This volume presents disciplinary as well as integrative methods to assess these impacts considering the interactions between climate variability and change, water availability, land-use systems, and quality of life. Taking the semiarid northeastern area of Brazil as an example, a wide range of expertise and knowledge (from integrated water analyses to transregional migration) is necessary to understand the complex relationship between natural and socio-economic systems.
