Reconstruction of the hydrological record of Lake Ngami, Botswana, since 1849. The decline of the lake can be attributed to a progressive cessation of inflow in the Thaoge River system due to blockage by papyrus, itself partly attributable to human

Late Pleistocene and Holocene lake level fluctuations in the Lake Bogoria bassin, northern Kenya Rift Valley in Palaeoecology of Africa and the surrounding islands-Vol 13.
Lake Bogoria is a closed-basin, saline alkaline lake in the Kenya Rift Valley. The sedimentology and mineralogy of three long drill-cores from the lake floor, and the marginal fluvio-deltaic and littoral deposite are studied here. During the late
Pleistocene, the lake fluctuated but was mostly low and saline (anoxic)| calcrete, dolocrete and pedogenic zeolites developed in marginal soils. Following this dry phase, a regional increase in humidity during the terminal Pleistocene and early Holocene, led
to a marked rise in lake level. The lake waters were considerably fresher than today allowing expansion of both fauna and flora, and may periodically have overflowed northwards into the Baringo sub-basin. Further fluctuations occured throughout the Holocene

Late Quaternary history of Lake Besaka, Ethiopa in Palaeoecology of Africa and the surrounding islands-Vol 13.
Lake Besaka, as a groundwater-fed lake which appears to have overflowed eastwards into the Awash during the late Pleistocene and perhaps again during the earliest Holocene, is not a sensitive indicator of climatic change. Only two major
transgressions are so far evident in the late Quaternary depositional record of the lake, one dated to about 11,000-12,000 BP, the other perhaps 10,000 years older. Tectonic and volcanic factors have undoubtedly modulated the response of Lake Besaka to climatic

High levels of Lake Malawi during the Late Quaternary in Palaeoecology of Africa and the surrounding islands. Volume 15. Southern African Society for Quaternary research. Proceedings.
Lake Malawi levels have been as much as 5 m above modern peak values during the early? Holocene but, until more is known about changes in the overflow, the palaeoclimatic significance of these high levels must remain in doubt. In an attempt to view
modern flooding problems in the longer term perspective, beaches representing high lake levels within approximately the last 2 000 years are being studied in detail.

Further Late Quaternary leaf fossils from Lake Bosumtwi, Ghana in Palaeoecology of Africa and the surrounding islands-Vol 13.
A further 12 species of tree brave been identified from leaf fossils preserved in terminal Pleistocene-early Holocene lacustrine sediments exposed above the present shore of Lake Bosumtwi. Our earlier finding has been confirmed that forest

This paper presents results of a palynological analysis of a 15.5 m sediment core from Lake Naivasha. The core spans a little more than the last 20,000 years. The record is long enough to include the last glacial maximum in temperate latitudes
and the switch to interglacial conditions at about 12,000 yr B.P. The record also covers the period of maximum rainfall in East Africa, 9 000 to 5 000 yr B.P., a time marked by high lake levels.
