In an era of climate change, the need to manage our water resources effectively for future generations has become an increasingly significant challenge. Indigenous management practices have been successfully used to manage inland water systems around the world for thousands of years, and Indigenous people have been calling for a greater role in the management of water resources. As First Peoples and as holders of important knowledge of sustainable water management practices, they regard themselves as custodians and rights holders, deserving of a meaningful role in decision-making. This book argues that a key (albeit not the only) means of ensuring appropriate participation in decision-making about water management is for such participation to be legislatively mandated. To this end, the book draws on case studies in Australia and New Zealand in order to elaborate the legislative tools necessary to ensure Indigenous participation, consultation and representation in the water management landscape.
