Item Assessment of hydropedological characteristics at medium-sized landslide sites in Manafwa catchment, Mount Elgon, Uganda(Taylor and Francis, 2024-05-17) Kutosi,Moses; Bamutaze,Yazidhi; Nakileza,Bob.R; Kisira, Yeeko; Gabiri,GeofreyThough strongly linked to landslides, hydropedological characteristics are inadequately investigated in Manafwa catchment. This study investigated hydropedological characteristics at medium landslide sites in Manafwa catchment. The design included 12 infiltration experiments that were conducted at each site. To determine the selected soil physical properties, composite soil samples were extracted from the infiltration sites for soil laboratory analysis. Soil cores were extracted to determine saturated hydraulic conductivity (Ksat) and bulk density. The observed high infiltration rates and rapid Ksat underscore the susceptibility of the studied sites to landslide hazards. Additionally, soil organic matter, clay content, and bulk density further contribute to the understanding of the hydropedological factors influencing land slide occurrences. These findings reveal the need for comprehensive investigations into hydropedologi cal characteristics of other landslide categories to assist in landslide risk assessment and management strategiesItem Farmers Coping and Adaptation Mechanisms to PerceivedChangesandVariability in Climate(East African Journal of Environment andNatural Resources, 2024-08-28) Oriangi,George; Edekebon,Elaijah; Ologe,Daniel Ochieng; Bamutaze,YazidhiThere is a growing global concern about the detrimental effects of climatechange and variations on rain-fed agriculture. This study determinedhouseholds’ perceptions of changes and variations in climate and institutional roles in farmers' coping and adaptation mechanisms to changes and variationsin climate in Paicho Sub County (S/C), Gulu district in Northern Uganda. Datawas collected through structured household interviews and analyzedusingregression analysis and descriptive statistics. Findings showed that respondentsperceived rainfall and temperature to be the climatic parameters that hadchanged most with rainfall onset largely unpredictable. The major copingmechanisms to changes and variations in climate included: buying foodfromthe market, exchange of labor for food, and getting food help fromrelatives, community, and food agencies while, the major adaptation mechanismsincluded: getting jobs outside agriculture, adjustment of plantingdates, diversification of production, carrying out mixed cropping, and growingimproved crop and animal varieties. Additionally, the gender (P<0.05), thesizeof the land (P<0.05), and the age of the household head (P<0.05) were foundtobe the mostsignificant factorsinfluencing adaptation mechanisms. Furthermore, the role of existing institutions in community adaptation to changes andvariations in climate included: making decisions on planting time, providingaccess to information relevant to coping and adaptation, providing access tocredit, governing entitlements, and capacity building. In conclusion, thereisaneed for better and new crop varieties that can survive under changed andvariedclimatic conditions, and a need for more enhanced adaptation mechanisms.Item Perceptions of resilience to climate-induced disasters in Mbale municipality in Uganda(Taylor and francis group, 2020-01-29) Oriangi,George; Albrecht,Frederike; Bamutaze,Yazidhi; Mukwaya,Paul Isolo; Nakileza,Bob; Pilesjo,PetterResilience has been raised as a core task within disaster risk reduction frameworks, yet it remains difficult to implement these global ideas in local communities. This study used Community Based Resilience Analysis Approach to investigate the components that are perceived as important in resilience and the extent to which these components have been achieved. It explored the trend of resilience and beneficial interventions for building resilience as perceived by interviewed participants in Mbale Municipality in Eastern Uganda. The study results indicate that access to education, healthcare, employment, peace and security were the most important components of resilience. Respondents perceived to have progressed in accessing credit, building productive farms and sustaining peace and security byJuly 2017. However, they assessed a lack of diverse income-generating activities, access to insurance, food security,employment and health care. Moreover, the study showed that respondents from marginalised parts of the municipality experienced decreasing resilience while respondents in other divisions had increased resilience. These results provide context-specific components of resilience by the local people. This can inform the formulation of resilience indices and bear relevance for policy-makers and practitioners to understand areas to invest more resources to achieve resilience.Item Variabilities and Trends of Rainfall, Temperature, and River Flow in Sipi Sub-Catchment on the Slopes of Mt. Elgon, Uganda(water, 2021-06-30) Luwa,Justine Kilama; Majaliwa,Jackson Gilbert Mwajalolo; Bamutaze,Yazidhi; Kabenge,Isa Pilesjo; Oriangi, George; Mukengere,Espoir BagulaThe variabilities in rainfall and temperature in a catchment affect water availability and sustainability. This study assessed the variabilities in rainfall and temperature (1981–2015) and river flow (1998–2015) in the Sipi sub-catchment on annual and seasonal scales. Observed daily rainfall and temperature data for Buginyanya and Kapchorwa weather stations were obtained from the Uganda National Meteorological Authority (UNMA), while the daily river-flow data for Sipi were obtained from the Ministry of Water and Environment (MWE). The study used descriptive statistics, the Standardised Precipitation Index (SPI), Mann Kendall trend analysis, and Sen’s slope estimator. Results indicate a high coefficient of variation (CV) (CV > 30) for August, September, October, and November (ASON) seasonal rainfall, while annual rainfall had a moderate coefficient of variation (20 ˂ CV ˂ 30). The trend analysis shows that ASON minimum and mean temperatures increased at α = 0.001 and α = 0.05 levels of significance, respectively in both stations and over the entire catchment. Furthermore, the annual and March, April, and May (MAM) river increased at an α = 0.05 level of significance. A total of 14 extremely wet and dry events occurred in the sub-catchment during the post-2000 period, as compared to five in the pre-2000. The significantly increased trend of river flow could be attributed to the impacts of climate and land-use changes. Therefore, future studies may need to quantify the impacts of future climate and land-use changes on water resources in the sub-catchment. may need to quantify the impacts of future climate and land use changes on water resources in the sub-catchment
