This report provides a detailed analysis of how migration is connected to land ownership, land use change, and land degradation. It begins with an overview of general migration theories, and then quickly focuses on how environmental factors influence migration. After introducing a well-established conceptual model to guide further analysis, the report takes the reader through a large number of specific examples of migration associated with land degradation and droughts, from a range of countries and regions. Emphasis is placed upon the influences of socio-economic and political processes, as well as the complexity of interactions, and the heterogeneity of the potential migration outcomes.
