While the interdependence of the different aspects of water security and the relevance of ethical and distributive aspects is acknowledged in both policy circles and academia, a comprehensive introduction to water ethics is still missing. This book aims to fill that gap, by exploring the common thread that follows from three current interrelated debates: the allocation of water resources, the human right to water, and the commodification and privatisation of water services. These questions create a plea for alternatives to the predominantly consequentialist approach to dealing with water issues. The author explores the normative and ethical aspects of flood and water-related risks, and looks at the topic of responsibility: who should be responsible for correcting inequities, or taking remedial action in the case of pollution? These and other questions to be linked to ongoing discussion in other disciplines within philosophy, such as environmental ethics, climate ethics, the ethics of technology and climate justice, making this text important across a wide range of courses for upper undergraduate and graduate students.
