My next two day were spent using my old teaching skill in partnership with the UNDP presenting the sustainability aspects of the water project to the community. From a Rotary standpoint our system is a low maintenance gravity system that will provide clean water to the village. Other than pipe maintenance, no other requirement are necessary for the system. One of the primary purposes for my travels to Cameroon was to determine if we can cap the springs. If this were possible we would be bringing virtually bring spring water to the front door.
Finally To Work:
Developing Sustainability of the Wum Water Project.
The Rotary/UNDP (United Nations Development Project) Partnership Training Program
I have come to learn that partnerships are extremely important in projects of this nature. So I would like to tell you why this partnership is so important to success of Rotary’s Wum Water project. The UNDP provides a re-forestration and watershed protection program to protect and enhance the watersheds throughout many developing countries. This system is ingenuous and one that I doubt any Rotarian or water engineer would ever concieve of.
Here is how it works. The watershed or catchment as it is called, is a rather large body of land in which rain water collects as is seeps down a drainage. In our case the catchment consists of approximately 500 hectors. The vegetation covering this area consists of high grass, an assortment of various tree species, and dense vegetation around the spring areas.
Re-forestration solves a number of problems with catchments that dramatically reduce or eliminates the following: cattle grazing, contamination of the water system, elimination of villagers entering the catchment in search of fire wood, increased water retention in the soil, and a revenue sources to pay for the system maintenance. All that just by planting the right trees in the watershed.
This is how it works.
- The circumference of the watershed area is approximately four miles and to fence it with barbed wire expensive and ineffective. To solve this problem thorny trees interspersed with low growing prickly shrubs are planted to protect the perimeter of the water shed. The thorny trees keep the cattle out and the low growing shrubs supports this as well. Both inhibit the entrance of cattle and reduce the slash and burn fires from entering the watershed.
- The most common trees in the area are eucalyptus, and are removed as they deplete water from the soil.
- On the other hand, there are replaced by trees that return water to the water shed and by its natural shading reduce evaporation.
- Within the watershed trees are then planted that produce profuse flowers for bee keeping. This is highly profitable product which augments the cost of maintenance for the water system.
- Harvesting of firewood is a major problem as wood is the primary source for cooking. It is scarce. To discourage this practice trees are cut down they are cut down and replace with indigenous income producing trees such as orange, avocado, lemon.
All I can say is, what an ingenious system.
