The book analyses processes of desertification from a social science perspective, and unravels the policy related to drivers of desertification. Desertification is addressed both as a concept surrounded by a multitude of different discourses and as a tangible unsustainable process that is connected to a complex set of policies and changing land management practices. The focus will be on Southern Europe, where desertification has been a long-standing problem in many areas, and where in some places the loss of productive capacity has worsened considerably over the last few decades. By focusing on four specific case study areas in Portugal, Spain, Italy and Greece, the scope of the book will cover the 'human dimension' of desertification, exploring in particular how the framework of existing policies has affected land management decisions and desertification processes. The emphasis will be on how policies may have contributed to desertification alleviation and mitigation, as well as to a worsening of desertification processes.
