    Spatial and temporal variations of trophic state conditions of Lake Bunyonyi, south‑western Uganda
    (Applied Water Science, 2023) Saturday, Alex; Lyimo, Thomas J.; Machiwa, John; Pamba, Siajali
    The study was conducted to assess the spatial and temporal variations of the trophic state condition of Lake Bunyonyi between October 2019 and September 2020. Secchi depth (SD), total phosphorus (TP) and chlorophyll-a (Chl-a) concentration were measured to aid the quantification of trophic state condition of the lake using Carlson trophic state index (CTSI). The trophic state index (TSI) values based on SD, TP and Chl-a values were 60.82 ± 5.35, 68.99 ± 11.04 and 61.74 ± 7.51, respectively. March 2020 recorded the highest mean CSTI value (70.14 ± 4.04), while in September 2020, the lowest mean value (58.03 ± 6.22) was obtained. Based on CTSI values, the lake was eutrophic in both dry and wet seasons albeit with differences in the values. The eutrophic state of the lake is possibly attributed to nutrients inflow into the lake via runoff and drainage from farmlands. The negative value of TSI-Chl-a–TSI-TP deviation pointed out that the lake is not phosphorus limited, while the positive TSI-Chl-a–TSI-SD mean deviation value revealed the effect of Chl-a and TP on the lake’s transparency. The study recommends the necessity to develop guidelines for the trophic status monitoring of Lake Bunyonyi since results suggest the deteriorating lake condition.

    Wetland Conservation and Management Practices in Rubanda District, South-Western Uganda
    (East African Journal of Environment and Natural Resources, 2022) Turyasingura, Benson; Saturday, Alex; Hirwa, Hubert; Fatima, Sule Mohammed; Tabukeli, Musigi Ruhiiga; Ayiga, Natal
    Worldwide, wetlands cover about 9% of the land surface and are recognized as bio-networks that offer living prospects when managed properly. Despite the present resource management regime, many wetlands in Uganda are being degraded due to mining, construction, agricultural and industrial activity, and little attention has been paid to the effectiveness of wetland conservation. The goal of this research was to evaluate Nyamuriro wetland conservation and management practices in Rubanda District, Uganda. The study was guided by specific objectives, which included investigating the management approaches used in Nyamuriro wetland conservation, identifying the management challenges preventing Nyamuriro wetland conservation, and evaluating sustainable solutions to the challenges preventing Nyamuriro wetland conservation. The study employed a descriptive cross-sectional research design that included qualitative and quantitative data gathering and analysis techniques. A total of 109 people participated in the study using simple random and purposive sampling approaches. In this study, data was collected using questionnaires, key informant interviews, and observational approaches. Most respondents strongly agree that wetland restoration is the best management approach for Nyamuriro wetland conservation (Mean = 4.87, SD = 0.547). Corruption was the most significant hindrance to the conservation of Nyamuriro wetland among the management problems (Mean = 3.41, SD = 0.467). Overall, the data showed that there was a significant positive association between conservation management techniques but not between viable Nyamuriro wetland conservation measures. The study recommended that strict laws and procedures should be put in place to ease restrictions on wetland conservation.
