The aim of `Water Security Tools and Policy' is to investigate and provide a working familiarity with established and cutting-edge analytical, decision-making, and development tools (such as water footprinting or climate impacts assessment) for effective water security policy. It will utilise case study material, physical models, computer exercises and material brought or sourced by students to audit the water security of a system of interest (e.g. city, region, country, irrigation scheme). The students will record and assess the factors that affect water security such as laws and legal frameworks; water supply and demand volumes; institutions for managing water; climate change science and models; climate risks and adaptation; and future projections regarding societal change. Actions to address security will be discussed and formulated.
