Although modern climate conditions in the 26 June 2009 Central Kenya Rift are very similar for these basins, hydrology and hydrochemistry of present-day lakes Accepted 9 July 2009 Nakuru, Elmenteita and Naivasha contrast dramatically due to tectonically controlled differences in basin geometries, catchment size, and fluvial processes. In this study, we use eighteen 14Cand40Ar/39Ar dated fluvio-lacustrine sedimentary sections to unravel the spatiotemporal evolution of the lake basins in response to tectonic and climatic influences. We reconstruct paleoclimatic and ecological trends recor- ded in these basins based on fossil diatom assemblages and geologic field mapping. -

Notes on the Ground and Polished Stone Axes of East Africa
NOTES ON THE GROUND AND POLISHED STONE AXES OF EAST AFRICA. By MARY D. LEAKEY. During the last thirty years, a number of polished stone. axes have been discovered in East Africa. The majority of these have been chance finds made by farmers in the course of plough• ing or other agricultural activities, with the result that little reliable evidence has been recorded concerning associated mate• rial or stratigraphy. In spite of this regrettable lack of data, the five types of axe represented among the 22 complete specimens known to exist appear to be sufficiently interesting and their occurrence in Kenya and Tanganyika, of sufficient importance to merit a short description. Since the term "neolithic" is frequently applied to ground and polished stone implements and since it is permissible to assume for the present that the East African axes belong to this cultural phase, it may not be out of place to summarise the bases on which the term is applied in the area under review. It seems that for the greater part of Africa, excluding the Egyptian field, the characteristics of the neolithic stage in cultural development are generally recognised as being somewhat different to those understood for Europe. There, the combination of agriculture, the domestication of stock, pottery and the grinding and polishing of stone implements are usually considered essential criteria and are frequently found together in the same context. In East Africa, on the other hand, where our knowledge is still extremely scanty, although two or more of the above features may be present, all four have not hitherto been discovered in association. -

Case Study Report For
Case Study One Indigenous Peoples’ Rights in the Kenya Lake System in the Great Rift Valley 1 By DR. KANYINKE SENA Indigenous Peoples’ Rights in the Kenya Lake System in the Great Rift Valley 1 CASE STUDY ONE Indigenous Peoples’ Rights in the Kenya World Heritage (IIPFWH), as a standing global Lake System in the Great Rift Valley body aimed at representing indigenous peo- ples voices in the World Heritage Committee processes.5 The Committee referred to the establishment of the IIPFWH, “As an impor- tant reflection platform on the involvement of Indigenous Peoples in the identification, conservation and management of World Heritage properties, with a particular focus on the nomination process.” 6 Pursuant to the mandate of the Forum, this report aims at analyzing Indigenous Peoples’ involvement in the Kenya Lakes System in the Great Rift Valley World Heritage Site. The report is as result of extensive literature re- view and interviews with communities in and around the lakes that comprise the Kenya K. Sena: Lake Bogoria Lakes System. The Kenya Lake System in the Great Rift Val- ley is a World Heritage site in Kenya which comprises three inter-linked, relatively shal- low, alkaline lakes and their surrounding territories. The lakes system includes Lakes Elementeita, Nakuru and Bogoria in the Rift Valley. The lakes cover a total area of 32,034 and was inscribed as a world heritage site in 2011. The inscription was based on the lakes system outstanding universal values and criterion (vii), (ix) and (x) as provided for, under paragraph 77 of the Operational Guidelines for the Implementation of the World Heritage Convention. -

Kenyan Stone Age: the Louis Leakey Collection
World Archaeology at the Pitt Rivers Museum: A Characterization edited by Dan Hicks and Alice Stevenson, Archaeopress 2013, pages 35-21 3 Kenyan Stone Age: the Louis Leakey Collection Ceri Shipton Access 3.1 Introduction Louis Seymour Bazett Leakey is considered to be the founding father of palaeoanthropology, and his donation of some 6,747 artefacts from several Kenyan sites to the Pitt Rivers Museum (PRM) make his one of the largest collections in the Museum. Leakey was passionate aboutopen human evolution and Africa, and was able to prove that the deep roots of human ancestry lay in his native east Africa. At Olduvai Gorge, Tanzania he excavated an extraordinary sequence of Pleistocene human evolution, discovering several hominin species and naming the earliest known human culture: the Oldowan. At Olorgesailie, Kenya, he excavated an Acheulean site that is still influential in our understanding of Lower Pleistocene human behaviour. On Rusinga Island in Lake Victoria, Kenya he found the Miocene ape ancestor Proconsul. He obtained funding to establish three of the most influential primatologists in their field, dubbed Leakey’s ‘ape women’; Jane Goodall, Dian Fossey and Birute Galdikas, who pioneered the study of chimpanzee, gorilla and orangutan behaviour respectively. His second wife Mary Leakey, whom he first hired as an artefact illustrator, went on to be a great researcher in her own right, surpassing Louis’ work with her own excavations at Olduvai Gorge. Mary and Louis’ son Richard followed his parents’ career path initially, discovering many of the most important hominin fossils including KNM WT 15000 (the Nariokotome boy, a near complete Homo ergaster skeleton), KNM WT 17000 (the type specimen for Paranthropus aethiopicus), and KNM ER 1470 (the type specimen for Homo rudolfensis with an extremely well preserved Archaeopressendocranium). -

The Estimation of Lake Naivasha Area Changes Using of Hydro-Geospatial Technologies
http://dx.doi.org/10.4314/rj.v1i1S.3D The Estimation of Lake Naivasha Area Changes Using of Hydro-Geospatial Technologies A. Ruhakana Soil and Water Management Research Program Rwanda Agriculture Board, Huye, Rwanda [email protected] Abstract: Remote Sensing (RS) and Geographical Information System (GIS) were proved as new technology to intervene in monitoring, managing and protecting environmental resources among others lake and water reservoir are mostly anxious resources. The objective of the study was to estimate the surface area change of the lake Naivasha using RS, GIS techniques and hydrological modeling for the lake water balance. Landat images Thematic Mapper/Enhanced Thematic Mapper Plus (TM/ETM+) taken respectively in the same month of January 1986; 1995; 2003 and 2010 were the input data used to assess the different changes of the lake area on one hand. on other hand the spread sheet data set helped to build the hydrological model to estimate the long term lake Level fluctuation, the rainfall versus evaporation as in flow and out flow from the lake. The lake volume showed the dynamic of ground water to simulate the long-term fluctuation of the lake level. The lake area changes from the model were calculated from the spread sheet input data from 1986 to 2003 while the lake area changes from the Landsat images were calculated from 1986 to 2010. The comparative results from the area lake changes both from Landsat images and hydrological model confirmed the correlation results, 45.72 Km2 or 32.03 % in 2010 for the Landsat while the hydrological model estimated to 12km2 or 8% area reduction in 2003.
