摘要

Remotesensing and GIS applications are being widely used for various projectsrelating to natural resource management. Forests are very important nationalassets for economic, environmental protection, social and cultural values andshould be conserved in order to realize all these benefits. Kenya’s forests arerapidly declining due to pressure from increased population, technologicalinnovation, urbanization human development and other land uses. Mau forest isone of the major forests in Kenya that is a catchment area for many Great RiftValley lakes within the country and faces a lot of destruction. Continueddestruction of the Mau forest will cause catastrophic environmental damage,resulting in massive food crises and compromising the livelihoods of millionsof Kenyans, and the possible collapse of the tourism industry. The purpose ofthis research was to investigate the relationship between the increasing rateof deforestation and the reduction of the volumes of water in the neighboringlakes between the years 1989 to 2010. Satellite images from Landsat-5 ThematicMapper (TM) and Landsat-7 Enhanced Thematic Mapper (ETM+) were used for thedetection of changes in the Mau forest and the dynamics of the neighboringwater bodies that included lakes: Naivasha, Baringo, Nakuru, Elementaita andBogoria. The research showed that from a period of 1989 to 2010 Mau forest hasbeen decreasing due to deforestation and the water bodies have irregulardynamics in that, from 1989 to 2000, there was rise in the volume of water,this is attributed to the El Nino rains experienced in the country during theyear 1997 and 1998. But between 2000 and 2010 the volume decreased as theforest is also decreasing. It is recommended that the government createsawareness to sensitize the public on the importance of such forests ascatchment areas in Kenya.
