Description of the project: In the underprivileged district “La Ensenada de Chillon” in the north of Lima, women from the neighbourhood trained as bricklayers have built earth walls along the hillside to develop community-based urban gardens. Grey water from the houses is used for irrigation. The terracing – benefiting more than 40,000 residents – has made homes and roads more solid and resistant to earthquakes and heavy rains. 5,000 square meters of gardens are transforming crime-prone wastelands into productive green spaces, reducing gender-based violence and fights among youth. Plants absorb toxic emissions, improve air and life quality, and contribute to food security.
