2.2 Kisoro and KabaleBecause of their favorable environment regarding important factors for small-scalehydropower, such as climate and topography, the two districts Kisoro and Kabale wasthe choice of study area in Uganda. Another constraining factor for the selection of studyarea was the prevailing disturbances, caused by the rebels, Lords Resistance Army (LRA),in the northern parts of the country. Kisoro and Kabale districts are two, for Uganda,typical rural areas situated in the southwest of Uganda. In these districts, where Kisoroand Kabale towns are the administrative headquarters, the population is 220,312 and458,318 respectively. The region has a population density of over 400 inhabitants perkm 2 , which is one of the most densely populated regions in the world (www.ubos.org).The study area covers a mountainous region structured through numerous chains of hillsand ridges, which lies approximately 2000 m above sea level (see Figure 2.4). The highestpoint of the mountain is in the volcanic ranges bordering Rwanda in the southern part ofthe District and includes Mgahinga (3475 m), Muhavura (4127 m) and Sabyino (3645 m).These volcanic ranges are interspersed by wide saddles with valleys occupied by extensiveswamps. The volcanic mountains are part of six dormant and two active volcanoes ofVirunga range extending into Rwanda and the Democratic Republic of Congo (NEMA,1998).The rocky system underlying most part of the study area was influenced by the volcanicactions formed by the upsurge of the Western Rift Valley during the Pleistocene age. It ismuch eroded and altered and consists of metamorphic largely granitoid rocks, schist andfoliated granites, granochiorate and adamellite. The high relief in the southwestern partsof the study area has the characteristics of highly weathered and exposed granite rocks.The study area is underlain by three main rock systems, namely the Precambrian,Cenozoic and Mesozoic groups. The volcanic activity was characterized by theoutpouring of a great variety of potash rich in alkaline lava (NEMA, 1998).10

Photo: Bergström 2004.Kisoro District like Kabale District experiences two rain seasons a year with heavy rainsfrom March to May/June and from August to November. December to February andJune to August are dry seasons. The mean annual rainfalls in the Districts are 1000-1250mm (see Figure 2.5). The study area has a relatively low temperature where mean annualmaximum temperature is 23°-25°C in the dry spell and mean annual minimum record of10°-12.5°C (NEMA, 1998).20025175Precipitation (mm)150125100755025PrecipitationTemperature2015105Temperature (°C)00JANFEBMARAPRMAYJUNJULAUGSEPOCTNOVDECFigure 2.5 Kabale’s monthly mean precipitation (mm) 1918-1974 and monthlymean of the daily 24-hour temperature (°C) 1952-1971 Source: cdiac.esd.ornl.gov.11
