For thousands of years American Indians lived in equilibrium on traditional lands, adapting to seasons and landscapes. This issue of Water Resources IMPACT highlights the benefits and importance of incorporating the knowledge and concerns of First Peoples into water resources planning. The feature articles range from a discussion of the traditional knowledge First Peoples can offer water managers today, to the fact that many tribes still have not had their water rights completely quantified, leaving them without a legally secure source of water. All of the authors affirm that authentically engaging and collaborating with native peoples is good for the tribes and good for water managers. Click here for Water Resources IMPACT Issue.
