SummaryThe Equatorial Plateau is composed of several Lakes namely Lake Albert, Lake Edward and George, Lake Kyoga and Lake Victoria. Lake Victoria is the largest lake in Africa; its catchment area is divided between five countries: Burundi, Kenya, Rwanda, Tanzania and Uganda. The Victoria Nile flows from Lake Victoria into Lake Kyoga which is a shallow depression consisting in of a number of arms, many of which are filled with swamp vegetation. Then the Lower Victoria Nile leaves Lake Kyoga to Lake Albert. These lakes are known with the problem of the excessive growth of aquatic plants because of the spread of Eichhornia Crassipes (water hyacinth), Pistia Stratioctes (water lettuce), papyrus and others, through lakes Victoria, Kyoga, and Albert in Uganda. These weeds caused the presence of the huge areas of floating mats and islands consisted of such weed colonies. In case if no action plan is taken to control mats of water hyacinth and other floating weeds, together with floating papyrus islands, it is expected that further huge areas of these Lakes (mainly Lake Kyoga) will be invaded and covered by such vegetation. This weed attack will cause tremendous environmental damage to these lakes in future as they will affect the lakes hydrological system, water quality, navigation, fishing, landing sites, etc... This will involve the continuous loss for the water (evapotranspiration from the weeds) and the environment deterioration of the lake. This research aims to prepare environmental studies for the aquatic weeds in the equatorial lakes (Victoria, Kyoga, Albert) to find out the optimum solutions to mitigate from the negative impacts of the weed and utilizing them to improve the life conditions of these communities , in addition to studying the required measurement to prevent or control the re-growing of these weeds. The expected solutions will depend on the German technology and experience in this field. Study Methodology: 1- Establishing geographical information databases of the available data of Equatorial Lakes and the affected areas using Satellite images and maps. 2- Studying the existed types of aquatic weeds in these lakes and the ways to control them. 3- Studying the Environmental Impacts of these weeds to find out the expected risks on the biosphere, and technosphere, sociosphere environment. 4- Studying the solutions to overcome these problems by controlling these weeds using the German technology and the environmental Impact assessment for the different solutions to choose the optimum one. 5- Studying the utilizing of the removed aquatic weeds in industrial uses using the German technology and their impacts on the life conditions of these communities. 6- Studying the possibility of stop growing these weeds or controlling their amount using the German technology. Expected Outcomes: 1- Alternatives for controlling the aquatic weeds. 2- Alternatives for utilizing the aquatic weeds in the industrial uses. 3- Alternatives for stopping or controlling the re-growing of the aquatic weeds.
