Rainbow Ridge: How it all works

As well as being home for our CA Kids, Rainbow Ridge is also a sustainable village. Through our Development Aid Project we use Rainbow Ridge as a demonstration and teaching site for sustainability practices within the local community of Maili Sita. We believe that by teaching the local community how to provide for itself, it will then be better able to care for others, particularly local orphans.

A significant part of our Development Aid Project centres on permaculture, which is very much suited to third world subsistence societies. Permaculture is about integrating the natural ecological processes of plants, animals, water, weather and nutrient cycles with human needs to produce sustainable systems for food and energy production, shelter and infrastructure.



Teaching local workers how to build and use sustainable domestic support systems, including compost toilets, solar power (lights, energy, compost fans), methane gas (cooking), grey water filtration systems, and solar operated water pumps.

Building pens for pigs (breeding/selling), cows, chickens and goats to designated designs and free-roam areas. Holding two-month permaculture design courses, run by permaculture expert Greg Knibbs, for local workers and the local community. Swaling (trenches) Rainbow Ridge’s hilly site to harvest water.

Previously, about 86 per cent of water ran off the landscape. The annual maize crop was successfully grown despite drought-like conditions in this wet season period. Researching, sourcing and planting 2200 trees on site.

Developing vegetable gardens to capture rainwater and ensure year-round fresh and nutritious food. Sourcing a range of open pollinated vegetable and green manure seed to secure seed supply lines and to achieve better genetic diversity in the food supply.
