AI knowledge explainer

Rainwater Harvesting Cisterns is a high-impact adaptation method focused on water security and flood/drought adaptation. It has been documented for roughly 200 years and used by around 580 communities.

How the process works

Communities apply rainwater harvesting cisterns in the local context of Arid and semi-arid communities.
Traditional ecological knowledge guides timing, design, and maintenance decisions.
Local observations are combined with practical monitoring to adjust the method over time.

Why it helps resilience

The approach directly targets water security and flood/drought adaptation.
It relies on low-cost, repeatable practices that can be maintained by local groups.
Knowledge transfer across generations increases continuity and resilience.

How to start locally

Map local climate risks and identify where this method could be piloted safely.
Co-design the pilot with community elders/leaders and youth volunteers.
Track simple indicators monthly (e.g., water retention, crop health, participation).
