A Comparative Study of Grain Size Distribution and Mineralogy of Sandy Sediments between Kasekera Stream (Forested) and Mtanga Stream (Deforested) as Related to On Shore and Near Shore Environments: Lake Tanganyika, East Africa
ثبت نشده
چکیده
Lake Tanganyika is an ancient, tropical, fresh water lake associated with the Great African Rift. Due to active deforestation in many areas surrounding Lake Tanganyika, there is a measurable increase in sediment discharge entering the lake. Certain protected areas (protected from fire and deforestation) allow for comparison of sediment discharge, including grain size distribution and lithological characteristics, between deforested and forested regions.

Comparative analysis of organic matter and carbonate mineral distribution in shallow water surface sediments off the forested Kalande and deforested Ngelwa watersheds entering Lake Tanganyika, Tanzania
Introduction The impacts of watershed deforestation on lacustrine environments can dramatically affect the productivity of the littoral zone and strongly influence sedimentation rates. Many watersheds flowing into Lake Tanganyika (3°18’8°47’S, 29°05’ 31°18’E) from northern Kigoma region, Tanzania are currently experiencing the effects of deforestation to accommodate high human population densit...

Study sites The study sites were located along the northeast shore of Lake Tanganyika providing an ideal comparison between forested and deforested watersheds. Seven contrasting streams were studied; four of these streams were located in forested watersheds within the Gombe Stream National Park. Vegetation in Gombe Stream National Park consists of semi-deciduous woodland, wetter canopy forests ...

Lake Tanganyika is the oldest and largest of the East African rift lakes and therefore has the potential for recovery of temporally long paleoclimate records vital to our understanding of the climate history of the region (Figure 1). The resources of Lake Tanganyika are central to the viability of East Africa. As regional populations continue to expand, at an annual rate of 1.9-3.0%, demand for...
