ABSTRACT
Humanity faces a wide range of freshwater challenges and threats, from the failure to provide safe water and sanitation to all, to ecological disruptions and degradation, increasing violence over water resources, accelerating climate change, and failing institutions and infrastructure. In recent years, crises around minerals, energy, food, and water have stimulated new debates over definitions and concepts of sustainability—including whether the world is reaching a point where natural resource limits will constrain growing populations and economic expansion. Understanding the concept of “peak water” and the strategies that might be available to avoid these constraints is key to moving toward a more efficient and sustainable water future.
