Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
The aim of this study is to estimate and compare soil erosion, in the Mount Elgon region, eastern Uganda, during last decade. Possible trends changes erosion are linked precipitation/climate change as well land cover. Two different versions Revised Universal Soil loss Equation (RUSLE) implemented compared, one using slope length other flow accumulation steepness factor (LS). Comparisons modeled vs. field data indicate that RUSLE based on preferable. modeling carried out for years 2000, 2006,...
Abstract Over the last twenty years, Uganda has experienced sustained economic growth, increasing urbanization and a sizeable transformation of output from agriculture to services. However, this shift in sources wealth economy not been accompanied by employment out other sectors. This reflects an inability more modern sectors provide adequate for many Ugandans entering workforce every year. The relative underperformance largely explains why very high income inequalities still persist between...
Abstract Inadequate knowledge exists on the distribution of soil moisture and shallow groundwater in intensively cultivated inland valley wetlands tropical environments, which are required for determining hydrological regime. This study investigated spatial temporal variability along 4 positions segmented as riparian zone, bottom, fringe, slope an agriculturally used wetland Central Uganda. The determined regimes defined based deficit calculated from depth to table. For that, accuracy...
Purpose As climate change shocks and stresses increasingly affect urban areas in developing countries, resilience is imperative for the purposes of preparation, recovery adaptation. This study aims to investigate demographic characteristics social networks that influence household capacity prepare, recover adapt when faced with prolonged droughts or erratic rainfall events Mbale municipality Eastern Uganda. Design/methodology/approach A cross-sectional research design was used elicit...
Understanding variations in rainfall tropical regions is important due to its impacts on water resources, health and agriculture. This study assessed the dekadal patterns rain days determine intra-seasonal variability during March–May season using Mann–Kendall ( M K ) trend test simple linear regression S L R over period 2000–2015. Results showed an increasing of both amount (third seventh dekads). The light = 0.181; 0.350) wet 0.092; 0.118) also depict trend. rate increase third dekad...
Skillful rainfall prediction is important to sectors such as agriculture, health and water resources.The study assessed the ability of Weather Research Forecasting model simulate over Western Uganda for period 21st April 10th May 2013 tested six cumulus parameterization schemes.The root mean square error, error sign test method are used assess schemes along with an adapted contingency table.Results show that Grell-Fretas scheme better at simulating compared other while Betts-Miller-Janji'c...
Accurate and timely rainfall prediction enhances productivity can aid proper planning in sectors such as agriculture, health, transport water resources. However quantitative is normally a challenge for this reason, study was conducted with an aim of improving using ensemble methods. It first assessed the performance six convective schemes (Kain–Fritsch (KF); Betts–Miller–Janjić (BMJ); Grell–Fretas (GF); Grell 3D (G3); New–Tiedke (NT) Grell–Devenyi (GD)) root mean square error (RMSE) (ME)...
This study was conducted to map flood inundation areas along the Manafwa River, Eastern Uganda using HECRAS integrated with SWAT model. The mainly sought evaluate predictive capacity of by comparisons streamflow observations and derive, HECRAS, maps. Changes in Land-use/cover showed decrease forest wetlands, conversions into farmlands built-up from 1995 2017 have resulted increased annual surface runoff, sediment yield, water yield. Flood frequency analysis for 100-, 50-, 10-, 5-year return...
Low-input pastoral production systems provide up to 90 % of livestock and products consumed in Uganda. However, communities are increasingly faced with the challenge meeting their needs terms forage, a situation exacerbated by climatic variability. The study identified patterns forage availability quality, compared perceived normalized difference vegetation index (NDVI) determined drivers Karamoja sub-region. Over 12-month period, 75.3 respondents be sufficiently available differentiated...
This paper investigates the implication of climate change and variability on river flow within traditional irrigation farming system, vinyungu, in Iringa region, Tanzania. The study aimed at establishing areas that are most impacted by terms various adaptation strategies. It is based both primary data collected questionnaires distributed randomly among 189 farmers key informant checklists conducted with villages’ leaders Agriculture Extension Officers. Two focused group discussions were...
The purpose of this field study was to identify and characterize land use systems at varied spatial hierarchies, differentiate soil properties along landscape positions. Key data about existing were systematically collected in 12 sites. Topographic profiles across catchment geomorphic units identified show the relation typical a mountain ecosystem. We found statistically significant differences (p < .05) altitudinal gradients 52% samples also cover distribution characteristics slope...
