- ItemAssessment of Portable Water Quality in Kumi Town Council, Eastern Uganda.(Kampala International University, School of Natural and Applied Sciences, 2012-10) Omuna, DanielThe study was conducted in Kumi town council in Eastern Uganda. The study was experimental in nature geared towards determining physico-chemical, chemical and biological parameters of protected springs and borehole water, establish recommendation on how the communities in Kumi town Council can cope with the level of physicochemical, chemical and biological parameters of the water they consume. The water samples were collected twice from the sampled sources in the months of February 2012 and April 2012.
- ItemAssessments of the Forest, Poverty and Environmental Security Nexus in Uganda(IJSES, 2017) Akiyode, Oluwole O.; Nwankwo, Levi I.; Iyalomhe, Felix O.; Abdu, Yusuf A.; Tumushabe, Anne; Omuna, DanielThe environmental security and quality of every society are important in the determination of human development and socio-economic developments and its level of peace. The potential of environmental security of a location depends on the sustainable management of its forest. This is because of the ecological services being rendered by forest to the environment. Thereby, the societal system will need to encourage forest sustainability and security in order to continue to enjoy its ecological services. Forest utilization and poverty are interlinked, since the level of poverty may contribute to the rate of utilization of forest while the rate of utilization of forest contributes largely to environmental security and quality. The study examines the relationship between the level of poverty to the use of forest and its implication on environmental security using Uganda as a case. There has been a continuous reduction in the size of Uganda’s Forest Area (Percentage (%) of Land Area) since 1999. The study interconnects the continuous reduction of the Forest Area (Percentage (%) of Land Area) to the country’s well-being and livelihoods and suggests its implications on the environmental security and quality. The study advocates sustainable approaches to the management of forest.
- ItemPerformance of Biomass Briquettes as an Alternative Energy Source Compared to Wood Charcoal in Uganda(International Journal of Scientific Engineering and Science, 2017) Mahoro, Gloria Brenda; Omuna, Daniel; Eniru, Emmanuel InnocentThe environmental, financial and social questions, as well as the rapid increase in demand for energy fuels, emphasize the need to investigate and generate information on the performance of charcoal compared to briquettes as an alternative source of renewables in Kampala district. The study objective was to compare the performance of biomass briquettes as an alternative energy source to wood charcoal. The performance was measured using a modified water boiling test and a controlled cooking test. Data collected were analyzed using chi-square tests and cross tabulations on households’ socio-economic factors that promoted the popularity and use of briquettes or wood charcoal. Results from the modified water boiling test showed that the weight of wood charcoal, carbonized and non-carbonized briquettes consumed in boiling two litres of water is significantly different. From the controlled cooking test, the weight of charcoal used to cook dry beans is significantly higher than that of briquettes used to cook the same amount of beans. It was recommended that wood charcoal and briquettes perform similarly when used over short periods of time, but briquettes perform better over much longer periods.

- ItemSocio-Economic Factors Influencing Use and Adoption of Family-Sized Bio-digesters as Renewable Energy Sources in Ngoma District, Rwanda(Preprints (www.preprints.org), 2018-05-25) Musinguzi, Danson; Kayinamura, Emmanuel; Tumushabe, Ann; Omuna, Daniel; Eniru, Emmanuel I; Akiyode, Oluwole O; Mwebesa, Edson; Byarugaba, Dominic; Basamba, Twaha A.; Katongole, Hadijjah1) Background: The environmental, financial and social questions in Africa remain unanswered up-to-date, with the rapid increase in human population and the demand for fuel energy, trigger the need to generate data on the socio-economic factors influencing the knowledge of use and adoption of family-sized bio-digesters. The increasing prices of fossil fuels and taxes on energy sources require finding the alternative, clean and economical sources of energy for households in developing countries. Moreover, in Africa, the consumption of firewood and charcoal continues to increase, with wood fuel consumption predicted to increase by 2030 to over 140%. The study objectives were 1) to determine the socio-economic characteristics of the people in Ngoma district, 2) to assess socio-economic factors influencing people to use and adopt family-sized biodigesters. 2) Methods: Quantitative data collected with semi-structured questionnaires and interviews were analyzed using descriptive statistics. 3) Results: The results show that many households had not realized the potential benefits of biogas use and adoption in Rwanda. The study further found that a number of factors such as household income levels, socio-economic, technological, and institutional influence the household use and adoption of biogas energy. 4) Conclusions: At the end, the study suggests the need for all players such as Government, Non-Governmental Organizations (NGO's) and local communities to work together to provide incentives and favorable environment that can attract individual households to invest in biogas energy production and utilization.
