Impacts Water

In general, the decrease in water resources is expected to be accompanied by an increase in evapotranspiration due to rising temperatures. Land degradation, especially loss of forest cover, increases runoff and reduces rainwater infiltration to critical aquifers. Consequently, reservoirs of groundwater and surface water will be significantly affected both qualitatively and quantitatively. In the southern lagoon area, rising sea levels will reduce the hydraulic gradient streams, leading to siltation and increased frequency of flooding. Lakes and coastal lagoons are likely to become completely brackish due to sea-level rise and increased storm surges, further deteriorating these critical ecosystems. As a growing number of people move to urban areas, there will be increased demand for community water provisioning as well as wastewater treatment. One of Togo’s greatest concerns is the availability of clean drinking water. These resources are not always readily accessible and their quality can vary depending on aquifer depth. Moreover, the availability of Togo’s surface water resources is already jeopardized by seasonal and regional rainfall variation. An early onset to the dry season could further exacerbate this supply. Together, the city of Lomé and the Maritime region are home to 40% of the population and over 90% of domestic industries. Securing sufficient water for these regions under current management conditions is projected to grow increasingly challenging. Increased ability to store water during wet periods and increased access to irrigation during drought periods could help decrease vulnerability to the projected increase of dry days within the cropping season.
