How the process works

Communities apply three sisters planting in the local context of Northeast North America.
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 soil restoration and long-term farm productivity.
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).
