Conservation of the West African Black-Crowned Crane Balearica pavonina pavonina (Linn 1758) in the Sudano-Sahelian Wetlands of Northern Nigeria

The Black Crowned Crane Balearica pavonina is a resident of the Sahel and Sudan Savanna regions of Africa, ranging from the Senegal Basin and Guinea-Bissau Drainage in West Africa to the Western Ethiopian Highlands and South-West Rift Valley in East Africa. There are two black crowned-crane subspecies. The West African Crowned Crane, Balearica pavonina pavonina occupies the western part of this...

Regionalisation for lake level simulation – the case of Lake Tana in the Upper Blue Nile, Ethiopia

In this study lake levels of Lake Tana are simulated at daily time step by solving the water balance for all inflow and outflow processes. Since nearly 62% of the Lake Tana basin area is ungauged a regionalisation procedure is applied to estimate lake inflows from ungauged catchments. The procedure combines automated multi-objective calibration of a simple conceptual model and multiple regressi...

Hydrological Response to Climate Change for Gilgel Abay River, in the Lake Tana Basin - Upper Blue Nile Basin of Ethiopia

Climate change is likely to have severe effects on water availability in Ethiopia. The aim of the present study was to assess the impact of climate change on the Gilgel Abay River, Upper Blue Nile Basin. The Statistical Downscaling Tool (SDSM) was used to downscale the HadCM3 (Hadley centre Climate Model 3) Global Circulation Model (GCM) scenario data into finer scale resolution. The Soil and W...
