Obudho" of Agricultural Engineering, Egerton University, Njoro, of Zoology, Kenyatta University, Nairobi, Kenya Abstract Lake Baringo is a shallow, internal drainage, source of water for humans of the conditions conservation, sedimentation prevailing lake located in the Kenyan Rift Valley. The lake is an important and livestock, as well as a significant such as tourism, biodiversity as to greatly enhanced freshwater income source for local communities through activities and fish sold in local markets. The lake has been subject to over fishing, as well as a result of land use changes in the drainage basin. This paper provides an overview at Lake Baringo, and examines in detail the management response lake. The roles of the many and varied institutions in the lake basin's management internationally the situation is provided. funded projects designed to ameliorate to the problems are discussed, facing the and an analysis of Key words biodiversity, fishing moratorium, Global Environment Facility, Lake Baringo, lake basin management, land use change, sedimentation. use and livestock consumption. INTRODUCTION Lake Baringo is named after the local word 'Mparingo', Other important uses are income generation through tourism, biodiversity conservation which means lake. It is located in the eastern Rift Valley in and fishing activities. The composition Kenya, being one of the seven inland drainage lakes within species includes Oreochromis niloticus, Protopterus aethiopicus, the Rift Valley drainage basin. The lake has a surface area of about 108 km2 and drains a total area of 6820 km2 Three (Fig. 1). It is located namely, the Ilchamus, Pokots and Tugens.
