Analysis of fossil and genetic evidence provides strong support for an African origin ofHomo sapiens1, yet the timing of human expansions out of Africa has been the focus of recent debate2. The dating of most out-of-Africa fossils, and of the split between Eurasian and African populations bas...
Climatic mapping programs, which include interpolated climatic data estimated for numerous locations, were used to map these high risk areas in Africa, Australia and Latin America as well as in South East Asia. The predicted high-risk areas included several regions where CqLB has already been ...
The woodland biome of South Africa at lkm resolution was successively divided. Thirty year mean monthly temperature, total plant-available water balance of soil, elevation, landscape topographic position, and landscape soil fertility were used as input classification variables. The map data were ...
A world map of the Holdridge Life-Zone Classification, developed from approximately 8,000 meteorological records, is compared with a Holdridge Map with average temperature increments simulated by a. model of climate under elevated atmospheric CO<sub>2</sub> concentration. The largest changes are ...
the unification of the country has probably contributed to maintain the ancient genetic flows from central-north Europe in the north of the country and from Africa and Spain in the south13, with only a minor impact on the population structure of the following 150 years of history of the ...
Malaria transmission peaks in regions where temperature, rainfall, and humidity are close to optimal levels, as commonly observed across extensive areas of sub-Saharan Africa as well as in many parts of India [14, 25, 35, 36]. Changes in these factors due to climate change are anticipated ...

In the Volta basin of West Africa, where Ghana is situated, there are competing demands for water use both within and among the riparian countries of the basin. This is manifested in the numerous dams and reservoirs constructed throughout the basin for various purposes including industrial, ...
Fig. 1: Vegetation map of study location. Map of study cores from ODP Leg 160 Sites 966 and 967 in the Eastern Mediterranean with continental Northeast Africa and the fluvial component of the leaf wax shed, i.e., the Nile River watershed, highlighted in blue, with biomes46, lakes, and ...
Such a focus has undesired consequences on the effectiveness of adaptation measures as well as on our ability to prevent incommensurable losses. The article puts forward four strategic changes in adaptation policy that shift the focus away from markets and toward community-level visions of what a...
