Wetland Wastewater Systems |
|
In most parts of sub-Saharan Africa, there are little or no wastewater or sewage systems. Wetlands are natural wastewater treament systems and can be constructed or modified to treat wastewater very economically, especially in tropical climates. Many natural wetlands are currently being overloaded and degraded by pollutants. Often, areas of these wetlands can be modified and managed to treat wastewaters so that the remaining wetlands are protected. |

One of our biggest concerns is deforestation in our communities, which can be largely attributed to a need for fuelwood among local people. Biogas digesters may be a promising alternative to fuelwood and hence, a potential means of decreasing deforestation. Biogas digesters ferment household and animal waste and produce natural gas, which can be used for cooking and lighting. Biogas units have been used successfully in India for decades and have the potential to help people and decrease deforestation in our communities as well.
