Invest in small-scale irrigated agriculture: A national assessment on potential to expand small-scale irrigation in Nigeria.
(Agricultural Water Management, 2017)
Nigeria is faced with the daunting challenge to improve performance of its agriculture sector. Currently, crop production in Nigeria is predominantly rainfed; irrigation is perceived as an important means to boost agricultural ...
Introducing a new open source GIS user interface for the SWAT model
(Environmental Modelling & Software, 2016)
The Soil and Water Assessment Tool (SWAT) model is a robust watershed modeling tool. It typically uses the ArcSWAT interface to create its inputs. ArcSWAT is public domain software which works in the licensed ArcGIS ...
Improving irrigation access to combat food insecurity and undernutrition: A review
(Global Food Security, 2015)
Interventions aimed at increasing water availability for livelihood and domestic activities have great potential to improve various determinants of undernutrition, such as the quantity and diversity of foods consumed within ...
Evaluation of static and dynamic land use data for watershed hydrologic process simulation: A case study in Gummara watershed, Ethiopia
(CATENA, 2019)
Land Use Land Cover (LULC) change significantly affects hydrological processes. Several studies attempted to understand the effect of LULC change on biophysical processes; however, limited studies accounted dynamic nature ...
Experimental Evaluation of Conservation Agriculture with Drip Irrigation for Water Productivity in Sub-Saharan Africa
(Water, 2019)
A field-scale experimental study was conducted in Sub-Saharan Africa (Ethiopia and Ghana) to examine the effects of conservation agriculture (CA) with drip irrigation system on water productivity in vegetable home gardens. ...
Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia
(Journal of Soils and Sediments, 2018)
Agricultural intensification to meet the food needs of the rapidly growing population in developing countries affects water quality. In regions such as the Lake Tana basin, knowledge is lacking on measures to reduce non-point ...
Evaluation of CFSR, TMPA 3B42 and ground-based rainfall data as input for hydrological models, in data-scarce regions: The upper Blue Nile Basin, Ethiopia
(CATENA, 2017)
Accurate prediction of hydrological models requires accurate spatial and temporal distribution of rainfall. In developing countries, the network of observation stations for rainfall is sparse and unevenly distributed. ...
Potential of Water Hyacinth Infestation on Lake Tana, Ethiopia: A Prediction Using a GIS-Based Multi-Criteria Technique
(Water, 2019)
Water hyacinth is a well-known invasive weed in lakes across the world and harms the aquatic environment. Since 2011, the weed has invaded Lake Tana substantially posing a challenge to the ecosystem services of the lake. ...
A review of trends, constraints and opportunities of smallholder irrigation in East Africa
(Global Food Security, 2018)
Smallholder irrigation expansion would significantly increase agricultural production, and reduce food insecurity and poverty levels in East Africa. This paper reviews literature on trends, constraints and opportunities ...
Estimating the impacts of land use/land cover changes on Ecosystem Service Values: The case of the Andassa watershed in the Upper Blue Nile basin of Ethiopia
(Ecosystem Services, 2018)
Estimating the impacts of land use/land cover (LULC) changes in Ecosystem Service Values (ESV) is indispensable to provide public awareness about the status of ESV, and to help in policy-making processes. This study was ...
