Recent trends and anomalies in mean seasonal and annual temperatures over Sudan.
Abstract The mean temperature time-series over the period 1941–1996 for 13 stations across Sudan are examined on seasonal and annual bases to explore any possible trends in recent decades.Expand
Hydrological responses to land use/cover changes in the source region of the Upper Blue Nile Basin, Ethiopia.
This study found that expansion of cultivation land and decline in woody shrub/woodland appear to be major environmental stressors affecting local water resources, especially in relation to erosion and sedimentation in the upper Blue Nile River Basin. Expand
Towards understanding the integrative approach of the water, energy and food nexus.
Evaluation of the WEF nexus integrative debate can be carried out using four key criteria, namely ability to change current policy debates, issue and thinking novelty, practicability and measurability, and clearness and implementation roadmap. Expand
Gap filling and homogenization of climatological datasets in the headwater region of the Upper Blue Nile Basin, Ethiopia
Long-term time series of climatological data measured at meteorological stations provide one of the most authentic annals of climate in the past. However, there are a host of factors that affectExpand
Development and application of a drought risk index for food crop yield in Eastern Sahel
Abstract Drought is a common characteristic of the African Sahel whose agricultural productivity has been notoriously varying and declining as a result of this natural hazard. In this study,Expand
New approaches for estimating global solar radiation across Sudan
This study investigates the possibility of establishing monthly-specific equations for estimating global solar radiation across Sudan. Using data from 16 stations, stretching along sub-humid,Expand
Rainfall conditions and rainwater harvesting potential in the urban area of Khartoum
Abstract Runoff water management is among the inherent challenges which face the sustainability of the development of arid urban centers. These areas are particularly at risk from flooding due toExpand

The correlation between the time series of annual CV and extreme values for each of the four temperature variables shows generally that warmer climate in Sudan is associated with higher intra-annual temperature variability and vise versa, i.e. the CV is directly correlation with the highest value within the year, but inversely correlated with the lowest one.

A primary cause of soil erosion is the impact of rain. Therefore, understanding the altering rainfall characteristics and their effect on soil erosion is an issue of main concern. This is of utmostExpand
Implications of climate, land-use and land-cover changes for pastoralism in eastern Sudan
Abstract This study examines the changes in climate and land-use/land-cover (LULC) along the livestock seasonal migration routes in El Gedaref region (eastern Sudan). Analysis of temperature,Expand
