We analyze the potential effect of global warming levels (GWLs) 1.5 °C and 2 above pre-industrial (1861−1890) on mean temperature precipitation as well intra-seasonal extremes over Greater Horn Africa. used a large, 25-member regional climate model ensemble from Coordinated Regional Downscaling Experiment show that, compared to control period 1971−2000, annual near-surface is projected increase by more than 1 most parts Africa, under GWLs respectively. The highest increases are in northern...
The study evaluates the ability of ten regional climate models (RCMs) to simulate present-day rainfall over Uganda within Coordinated Regional Downscaling Experiment (CORDEX) for period 1990–2008. models' reproduce space-time variability annual, seasonal, and interannual has been diagnosed. A series metrics have employed quantify RCM-simulated pattern discrepancies biases compared three gridded observational datasets. It is found that most underestimate annual country; however, seasonality...
Abstract This study examines the effects of 1.5 °C and 2 global warming levels (GWLs) on intra-seasonal rainfall characteristics over Greater Horn Africa. The impacts are analysed based outputs a 25-member regional multi-model ensemble from Coordinated Regional Climate Downscaling Experiment project. climate models were driven by Coupled Model Intercomparison Project Phase 5 Global Models for historical future (RCP8.5) periods. We analyse three major seasons region, namely March–May,...
This study explores the implications of Solar Radiation Modification (SRM) on rainfall and temperature patterns over Eastern Africa region. The Geoengineering Model Intercomparison Project (GeoMIP) models under solar radiation modification G6solar G6sulfhur were evaluated against Shared Social-economic Pathways (SSPs). First, six GeoMIP are historical data found to capture climate in region fairly well. Secondly, run both SRM scenarios SSP for 2051-2080. Results show that scenario predict...
The study was conducted in the districts of Nakaseke and Nakasongola stratified into four farming systems crop dominancy, pastoralists, mixed livestock fishing. guided by two research questions: (1) how do community residents perceive climate change/variability? (2) What is trend nature variability does it compare with people's perceptions? Ninety eight percent (98%) respondents reported that routine patterns weather had changed last 5 to 10 years has become less predictable sunshine hours...
Abstract An assessment of the socio-economic implications landslide occurrence in Kigezi highlands South Western Uganda was conducted. Landslide is on increase and threatens community livelihoods these highlands. Detailed field investigations were undertaken with help local communities between June 2018 May 2020 to identify map recent visible scars Rukiga uplands In course inventories, 85 identified mapped using handheld GPS receivers produce a distribution for study area. A analysis...
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...
The study employed a Regional Climate Model (RCM), Providing Climates for Impact Studies (PRECIS), to examine the future climate scenarios over central Uganda cattle corridor districts of Nakaseke and Nakasongola in near (2021-2050) mid-century (2051-2080). was guided by two questions: what are projected temperature rainfall values relation IPCC Special Report on Emission Scenarios (SRES) A2 A1B same periods; how do they compare with new set known as Representative Concentration Pathways...
Abstract Climate change and air pollution are two interconnected daunting environmental challenges of the twenty-first century. Globally, stringent public health policies set to mitigate emissions near-term climate forcers (NTCFs) because they double as pollutants. While global impact NTCF mitigation has been investigated using coarse resolution models, fine scale regional impacts over East Africa not fully known. This study presents first 2021–2055 downscaled model results future scenarios...
Weather and climate issues have become increasingly recognized among the global challenges especially in era of change. Kampala city has faced a number flooding events past that led to serious damages many low lying areas city. A study was conducted one flood prone understand community perspectives on occurrence weather forecasting area. The main objective perceptions as well use information for early warning. Data collected from 400 respondents using structured questionnaire focused group...
Climate variability and change pose greater challenge not only to human life but the environment at large. This study sought evaluate significance of institutional factors in climate adaptation smallholder Irish potato farmers Rubanda District, South Western Uganda with objective assessing measures adopted by farmers, determining that influence adoption measures; evaluating challenges affect adapting farmers. A cross-sectional survey was undertaken collect data from 197 systematically...
Rainfall extremes have strong connotations to socio-economic activities and human well-being in Uganda's Lake Victoria Basin (LVB). Reliable prediction dissemination of extreme rainfall events are therefore paramount importance the region's development agenda. The main objective this study was contribute over region using a numerical modelling approach. Weather Research Forecasting (WRF) model used simulate 20-day period extremely heavy that observed March May season 2008. underlying...
The changing climate has negatively impacted food systems by affecting rainfall patterns and leading to drought, flooding, higher temperatures which reduce production. This study examined the ability of communities cope with insecurity due in Serere Buyende districts, are two different agro-ecological zones Uganda. We administered 806 questionnaires households, a sample size was determined using Yamane’s formula, snowball sampling method used select households. questionnaire sought...
Climate change and variability are a reality have had marked effects on both human ecological systems. Adaptation to such either directly or indirectly is viewed as novel way of reducing the spread associated risks. The study was conducted in Rubanda District with general aim evaluating effectiveness adaptation measures climate used by smallholder Irish potatoes farmers. Specifically, we sought appraise small-holder potato farmers’ perceptions about implications productivity. We undertook...
Abstract In East Africa, biomass burning in the savanna region emits nitrogen dioxide (NO 2 ), carbon monoxide (CO), and aerosols among other species. These emissions are dangerous air pollutants which pose a health risk to population. They also affect radiation budget. Currently, limited academic research has been done study their spatial temporal distribution over this by means of numerical modeling. This therefore used Weather Research Forecasting model coupled with chemistry (WRF-chem)...
Rainfall is a key climate parameter that affects most operations affect human life, especially in the tropics. Therefore, understanding various factors distribution and intensity of this rainfall important for effective planning among different stakeholders weather sectors. This study aimed at how intra seasonal characteristics, Consecutive Dry Days (CDD) Wet (CWD), two major seasons will change under future scenarios RCP4.5 RCP8.5 Uganda, covering periods 2021-2050 2051-2080. The results...
This paper explores the effects of climate variability on local communities living within and around Queen Elizabeth National Park (QENP), their coping mechanisms, challenges encountered. Data was collected from 250 respondents through questionnaires administered to small holder farmers, salt miners, fisher folks, as well in-depth interviews focus group discussions (FGDs) held with selected households in Katunguru, Lake Katwe, Kasenyi, Kahokya parishes park. The results indicated that...
Climate change affects both men and women which, in turn, shapes their varied contrasting perceptions of climate variability change. This paper examined the gendered among local communities Queen Elizabeth National Park Uganda.The objectives are threefold: - identify climatic shocks faced by communities; examine change; to compare with empirical meteorological data. study employed qualitative quantitative methods, data collected from 215 respondents using survey, interviews focused group...
