Analysis of spatial and temporal trend of hydro‑climatic parameters in the Kilombero River Catchment, Tanzania
(Springer Nature Limited, 2023-05-15)Inadequate knowledge on actual water availability, have raised social-economic conficts that necessitate proper water management. This requires a better understanding of spatial–temporal trends of hydro-climatic variables ... -
The removal of ciprofloxacin from synthetic wastewater in constructed wetland
(Elsevier, 2023-04-08)Considering the health effects of antibiotics in the environment, effective monitoring and treatment technologies are needed to mitigate social and environmental impacts. The present study was carried out to investigate ... -
Informing versus generating a discussion: Comparing two approaches to encouraging mitigation of soil erosion among Maasai pastoralists
(Elsevier, 2022-10-21)Soil erosion is a critical problem for pastoralist societies that rely on healthy grazing land for their livelihoods. Previous research suggests that unsustainable land management practice is one of the factors exacerbating ... -
Response surface optimization and modeling in heavy metal removal from wastewater—a critical review
(Springer Nature, 2022-04-08)The existence of hazardous heavy metals in aquatic settings causes health risks to humans, prompting researchers to devise effective methods for removing these pollutants from drinking water and wastewater. To obtain optimum ... -
Assessment of Groundwater Quality under Changing Climate in Ngorongoro Conservation Area, Tanzania
(American Society of Civil Engineers, 2022-07)Understanding the hydrochemical composition of water resources in the Ngorongoro Conservation Area (NCA, Dodoma, Tanzania) related to climate variability is essential for sustainable development. Thus, the current study ... -
Textile wastewater treatment in anaerobic reactor: Influence of domestic wastewater as co-substrate in color and COD removal
(Elsevier, 2022-10-28)Treatment of textile wastewater with domestic wastewater as co-substrate was investigated in this study. Combined textile and domestic wastewater at different mixing ratios (100:0, 80:20, 60:40) was treated under anaerobic ... -
Artisanal and small-scale mining in Tanzania and health implications: A policy perspective
(Elsevier, 2023-03-17)The mineral sector, especially its small-scale subsector, has become significant in the emerging economies of the Global South. Tanzania is the focus of this policy exposition paper because, aside from Ghana and South ... -
Non-competitive and competitive detoxification of As (III) ions from single and binary biosorption systems and biosorbent regeneration
(Springer Nature Switzerland AG., 2023-01-14)The quantity of studies reporting on single-metal sorption systems is increasing every day while the elimination of heavy metals in binary and multisolute systems is seldom reported. Therefore, the biosorption and desorption ... -
