In this course research areas are mutually supporting such as: science provides a sound empirical framework for legal research work of the Centre; International Water Law sets the context for permissible National Water Law - practical research tools developed by the Centre, in particular the Legal Assessment Model, allow practitioners to put this theory into practice; and research into the Legal Regulation of Water Services combines consideration of national parameters (i.e. government regulation) and multi-national water service providers. The combination of law and science is in fact often achieved here through our focus on Policy issues, an approach that offers our researchers the chance to consider both societal constraints (through, for example, law and economics) and those of the human and natural world.
