ItemDesign of a community Irrigation scheme to serve five small holder farmers(Makerere University, 2018-05) Bigirwamukama, HenryThere is unreliability of food security in Uganda caused by over reliance on rain fed agriculture by the biggest percentage (97%) of households in Uganda. Prolonged droughts always lead to food scarcity in the country. Irrigation is the solution this problem. However, farmers have not engaged in irrigation majorly because of the financial requirements. The major aim of this project therefore, was to design a community irrigation scheme to serve small holder farmers. A case study area was chosen to be Galiraya in Kayunga district where five farmers were growing upland rice on 4acres of land each, totaling to 20acres. Information on the climate, soil, topology, water availability, solar irradiance and wind was collected to aid in the design. Measurements of head, area, distance from the water source as well as coordinates of the place were also taken. Considerations were made on different types of irrigation and the manual hose pipe type was found most eligible because of its low costs involved. The irrigation water requirement for the rice was calculated by subtracting the total effective rainfall from the total rice water requirement and this was found to be 26.7m3/day. Total head(26m) was calculated by summing up the head of the area(16m) as measured by a hand held GPS, the head loss in the pipes(5m) and the dynamic head required by the nozzle(5m). A tank was designed to accommodate 30,000litres a day. The main pipe was also designed with diameter of 1.5inc, total length of 600m and was of flexible PVC material. The pump was designed by calculating the pump power from the flow rate and total head required. A suitable pump was chosen from available pumps and it had 550watts, maximum head of 52m and maximum discharge of 4m3/hr. the number of solar panels for the pump was determined from the pump power required and these were 6 In number. With this design, a topomap was created from the coordinates showing the design. A prototype was then set up in the area. Analysis was done to see the financial benefits of this system and it was discovered that through this, every farmer earns Shs 5,400,000 more per season with this system than when without it. It was concluded that setting up these kinds of irrigation schemes would increase food availability as well as increase the financial benefits of the farmers.

ItemIdentification and analysis of future land use conflicts in Wakiso district (land use conflict identification model-lucis)(Makerere University, 2018-05) Ojok, DanielLand use suitability analysis is a process of identifying the most appropriate location and distribution of future land uses (Collins, 2001; Malczewski, 2004). LUCIS is a goal driven model that attempts to derive probable future land-use patterns based on the three-broad land-use categories of agriculture, conservation and urban. LUCIS use analytical GIS models to determine where potential future conflicts may occur between competing land uses. Wakiso District has been one of the fastest growing places in Uganda over the past two decades. Population expansions driven by sociodemographic, economic and settlement factors are the major cause of land cover change. These changes in land cover due to land use activities lead to a variety of changes in the preference/suitability of land parcels for the different land use categories. In this study Landsat images (Landsat images) from 1990 to 2016 and LULC maps obtained from the ministry of Agriculture are used as the Primary sources of data. Image pre-processing, image classification (supervised) followed by prediction of future LULC and Future Space conflict diagram for the three major categories of Land uses identified. The results from the subsequent processes are analyzed and interpreted for meaning as regards what the future looks like if current growth and development trends are continued

ItemAn investigation into the relationship between human activities and environmental degradation in Kajjansi Town Council : Case Study Kajjansi Town(Makerere University, 2018-02) Nsangi, SusanKajjansi Town Council is in the first steps of the town Council, it’s a well zoned area and also protecting the environmentally sensitive areas, however due to many developments that are coming up and those that have been already established to gain from the benefits associated with this upgrade to Town Council status. This research seeks to investigate the relationship between human activities and environment degradation. With the objectives of the study being; to find out the human activities that have influenced environment degradation in Kajjansi town Council, to find out the factors which have contributed to environmental degradation in Kajjansi town council and to assess the impacts of environmental degradation caused by human activities in Kajjansi town council. The scope considered parishes of Bulwanyi, Bweya, Kitende, Nakawuka, Namuland, Nankonge, Ngongolo, Nsaggu, Sissa and Wamala though it considered Namulanda, Kitende and Sissa. The significance of the study was to help policy makers to recognize the impact of specific human activities in a developing city. Literature review, this section aimed to understand the nature and management of environmental degradation in Kajjansi Town Council, here we defined human activities as something that people do or cause to happen, and landuse was defined as the management and modification of natural environment or wilderness into built environment such as settlement. Causes of environmental degradation include industrialization, overpopulation deforestation, agricultural development, urbanization, water pollution, transport. The impacts of environmental degradation caused by human activities include loss of biodiversity, soil erosion. Possible strategies that can reduce environmental degradation included direct controls and regulation Section three: Research Methodology, focused on the description of the procedures that were employed in the study. The targeted population was Kajjansi Town Council local leaders, technocrats like planners. Multi-stage sampling was used and 55 households were chosen, political leaders 3 and technocrats 3. Data collection instruments are interview method, oral interview method, focus group discussion, photography. The research design used a descriptive survey design whereby both qualitative and quantitative data was collected. The research findings showed that men were interviewed than female, 90% of the people in Kajjansi town council could at least explain a bit of what they understood of environmental degradation. The main human activities in Kajjansi town council are agriculture, brick laying, iii transport and so on. It was noticed that agriculture was the main culprit for environmental degradation. Factors which contributed to environmental degradation overpopulation had over 31%. Section five is all about drawing sense, of the findings, and explaining why data was coming out that way. Lastly Section six drew conclusions and clearly explained the relationship between human activities and environmental degradation.
