Rainfall–interception–evaporation–runoff relationships in a semi-arid catchment, northern Limpopo basin, Zimbabwe

Chronic poverty in semi-arid Zimbabwe

Roadside flora in arid and semi-arid natural areas (Case study: Northern Khorasan province, Iran)

     Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...

Variability of Rainfall in a Semi-Arid Catchment in Burkina Faso

s The climate in the Sahel is marked by the spatial and temporal variability of rainfall. As the agriculture is mainly rainfed in Burkina Faso, the information about rainfall is crucial to help the farmers in their decisions. A network of wireless sensorscope stations is installed in the catchment of the Singou River (in the Gourma region of Burkina Faso) and monitor at a time step of 5 minutes...

The influence of a semi-arid sub-catchment on suspended sediments in the Mara River, Kenya

The Mara River Basin in East Africa is a trans-boundary basin of international significance experiencing excessive levels of sediment loads. Sediment levels in this river are extremely high (turbidities as high as 6,000 NTU) and appear to be increasing over time. Large wildlife populations, unregulated livestock grazing, and agricultural land conversion are all potential factors increasing sedi...
