When captured, filtered, and stored, it sustains households, feeds crops, and recharges soils.
When guided through terraces, bunds, or vegetative barriers, it prevents erosion and floods.
When combined with trees, roots, and local knowledge, it brings life back to degraded land.
These techniques are applied in highlands, midlands, drylands, and even cities, proving that rainwater harvesting is relevant and powerful everywhere !
In schools, on farms, and across fragile ecosystems, nature-based and community-led approaches form IRHA’s Water–Soil–Tree Triptych, a living cycle where each element supports the other and strengthens ecosystem resilience.

Before, I walked a long way for water. Now it's at home. I can spend more time with my family...
... And at my Blue School, we have clean water too. Life is really different now !
