Geochemical and physical characteristics of river and lake sediments at Naivasha, Kenya,uch that sediments introduced by rivers are transported in easterly and southerly directions, and are eventually deposited in the eastern, central and southern parts of the lake. Sedimentary deposition is also occurring in northern areas that once were protected by papyrus swamp vegetation but now o

Magnetic susceptibilities of lake sediment and soils on the shoreline of Lake Naivasha, Kenya, the lake’s only perennial inflow, the River Malewa in the north. Such particles originate from a hinterland that supports high intensity horticulture and are therefore a potential source of contamination.

In Crescent Island lagoon, the only regularly stratified site, hypolimnetic succession rates are lower than those in the epilimnion. Overall, community composition is controlled by mixing (and hence light regime) and nutrient availability. With ‘endless summer’ conditions and full

Population changes in sympatric Great and Long-tailed Cormorants (, and ,): the effects of niche ov methods, resting habitats and breeding timing. The decline in Long-tailed Cormorant numbers may be connected with increased disturbance by fishermen along the lake littoral, this species’ primary feeding location.

Book 2002ibrary of the effects of human follies. Lake Naivasha has achieved global importance in the past ten years because its waters are used to sustain the largest horticultural industry in Africa. The book highlights its fragility under such pressure and points out the way towards sustainable use of the water and the ecosystem.
