The aim of `Water Security Theory and Concepts' is to investigate the theory and conceptual frameworks that underpin research and policy work on `water security'. It will explore the background to rising concerns regarding the protection and use of water, and outline key problematics regarding its current treatment in research centres, in the literature and in practice. The module will examine the differences between water security and water resources security, and moreover, study the connections between water security with food, climate or energy security, and international, state and individual concerns regarding military security.
