Noah's Ark Zoo Farm hosts Ripple Effect volunteers for sustainable keyhole garden project

Volunteers from international charity Ripple Effect visited Noah's Ark Zoo Farm in early June 2026 to build a keyhole garden and plant pumpkins for the zoo's autumn Pumpkinfest. The keyhole garden is a circular raised bed designed for efficient water and compost use, featuring a central composting basket that reflects sustainable agricultural techniques supported by Ripple Effect across Africa.
