Lake Natron differs from that shown on a tectonic map by Krenkel (1925, p. This study provides an opportunity to evaluate the relative significance of human and climatic factors in middle Atlas lakes during the 20th century. Rift Valley Province of Kenya bounded by longitudes 35 30 and 360 00 E. Located in Northern Tanzania near Kenya border. This last phase was interrupted by some humid years or sub-periods (between 19, between 19) and dry years (between 19, between 19). Lake Natron is a salt or alkaline lake located in north Ngorongoro District of Arusha Region. The last period between 19 is characterised by increasing human activities (clearing of forest and development of agricultural techniques). The second period between 19 is very unstable with varying humidity. Las mejores ofertas para Kilimanjaro y norte de Tanzania (tamaño manual), Williams 9781910120828. The first period between 19 is humid with high lake levels, with fine particle size and relatively high contents of organic matter. Human activities have played a significant role in the lakes’ hydrological changes.The sedimentology, geochemistry and mineralogy results show three main periods. The paleohydrological reconstructions show fluctuating lake level since the mid-20th century. The multidisciplinary study of sediment cores from three middle Atlas lakes (central Morocco) provides a detailed record of environmental, climatic and anthropogenic changes.
