The convergence of social and environmental challenges is making us ever more aware of the limitations of a natural science that looks mostly at the physical environment and of a social science that looks mostly at the workings of human society. Contemporary challenges suggest the wisdom, in short, of collaboration, of seeking common ground with one another. The book contains detailed case studies, coupled with sophisticated analyses of theory and policy, focussing on the exchanges between natural and social science without diluting either perspective. This novel and well-structured textbook illustrates how different environmental issues and policies can be tackled in a collaborative way between natural and social science.
