Water justice is becoming an ever-more pressing issue in times of increasing water-based inequalities and discrimination. Megacities, mining, forestry, industry and agribusiness claim an increasingly large share of available surface and groundwater reserves. Water grabbing and pollution generate poverty and endanger ecosystems' sustainability. Beyond large, visible injustices, the book also unfolds the many 'hidden' water world injustices, subtly masked as 'rational', 'equitable' and 'democratic'. It features critical conceptual approaches, including analysis of environmental, social, cultural and legal issues surrounding the distribution and management of water. Illustrated with case studies of historic and contemporary water injustices and contestations around the world, the book lays new ground for challenging current water governance forms and unequal power structures. It also provides inspiration for building alternative water realities. With contributions from renowned scholars, this is an indispensable book for students, researchers and policymakers interested in water governance, environmental policy and law, and political geography.
