From rainwater harvesting in one Indian village to an aggressive conservation program in an American city, communities around the world are finding ways to manage the water demands of growing populations and expanding economies.

We’re inviting scientists, community leaders, water managers, conservationists and activists to share the lessons they’ve earned from the field—and the innovative solutions they’ve found.

We hope their stories will build a shared sense of community and motivate the public across the world to conserve freshwater and the diversity of life it sustains.

It’s hardly in a water-short region, so it may come as a surprise that Boston, Massachusetts, stands out as one of the biggest success stories in urban conservation in the United States.
