All OA schools are operated according to a model of self-sustainability.  Meaning, that once the school is fully constructed, operational, and registered with the government, it is capable of supporting itself.  OA’s model combines tuition-paying students with fully-dependent orphan students. Tuition received from parents of non-orphan students cover the costs of teachers’ salaries, school operation, plus the room and board of the orphans.  Also, by combining non-orphans with orphans, social stigmas and prejudices are reduced as opposed to being reinforced through orphan-only schools. Agricultural products on the school grounds adds food resources to the school and/or sales to the community

OAs Sustainability Projects

The OA commercial sustainability projects help create a sustainability model and support the mission of educating orphans in Africa.  Tanzania has staggering poverty and these projects not only help OA’s mission but also provide employment for local Tanzanian’s and business for local suppliers. These sustainability projects are helping create a healthy economy for the country.

The Shamba  (The Farm)

Outside Dar Es Salaam, TZ

5 acres of enclosed farmland houses approximately 150 hogs, milk cows, some cattle, guinea fowl, and chickens.  Animals are bred and sold.  Milk and eggs are also sold commercially.

Rice and corn are being grown on the farm.  The drought has affected crop growing and another well is needed for crops.

Samaki Fish tanks are raising Samaki to sell. Samaki is similar to Talipia. The commercial target is to sell to hotels and restaurants. This project is developing as OA is adding more tanks to complete the project. Solar power for special water pump for the tanks is now in operation.

Deep water well produces water for the farm. Solar power produces power for lights on the farm and solar power runs special pumps the fish tanks.


African Catfish is a developing project that can use wasted water from the fish tanks. Building a piped downhill drainage system to a catfish tank makes good use of wasted water, avoids erosion, and provides another revenue stream.

Bio-Gas Project

Most of the country, including our schools, cook with wood and charcoal. It creates a large carbon footprint in the country.   OA is developing a bio-gas project that will create gas from the farm’s cow and hog manure. This will allow our schools to cook over gas and reduce the need to find or purchase wood and charcoal. It will reduce the school carbon footprint.

Embe Shamba (Mango Farm)

10 acres of a mango farm. It takes 3 years to produce a viable mango crop to sell. This operation is still in development and needs additional deep water wells due to the drought. Wells will also reduce the dangers the women and children face while standing in the river to fill buckets with water to take back to the mango farm, such as contracting malaria from mosquitos and African crocodiles in the river.

14 additional acres are available for mango farming when OA is able to drill for irrigation well, pump, and water    tanks.  Mangos are sold commercially.









Nuru (Pellet) Factory

This is a new project creating food pellets for the fish tanks and to feed the farm animals.  Eventually the pellets will be sold commercially.
