Assessing the Impacts of Land Use and Climate Changes on River Discharge towards Lake Victoria
(MDPI, 2023-05-08)The Lake Victoria basin’s expanding population is heavily reliant on rainfall and river flow to meet their water needs, making them extremely vulnerable to changes in climate and land use. To develop adaptation and ... -
Assessment of Potentially Toxic Metals in Fish from Lake Manyara, Northern Tanzania
(Springer US, 2023-09)Elemental tracer concentrations of copper, lead, nickel and zinc, were assessed in the muscles of Oreochromis amphimelas and Clarias gariepinus from Lake Manyara, Tanzania, to evaluate their safety to consumers, specifcally ... -
Capacity building to strengthen nuclear security in the safety, operation and utilization of research reactors in Africa
(Egyptian Society of Nuclear Sciences and Applications (ESNSA), 2023-01-01)Research reactors are indispensable for developing countries to benefit from the many quiet applications of nuclear science and technology, particularly in health services, food security, water resources, education and ... -
Drivers, Impacts and Mitigation of Increased Sedimentation in the Hydropower Reservoirs of East Africa
(MDPI, 2021-06-16)Hydropower reservoirs are essential for the climate-neutral development of East Africa. Hydropower production, however, is threatened by human activities that lead to a decrease in water storage capacity of reservoirs. ... -
Evaluating Soil Carbon as a Proxy for Erosion Risk in the Spatio-Temporal Complex Hydropower Catchment in Upper Pangani, Northern Tanzania
(MDPI, 2021-10-15)Land use conversion is generally accompanied by large changes in soil organic carbon (SOC). SOC influences soil erodibility through its broad control on aggregate stability, soil structure and infiltration capacity. ... -
Novel use of portable gamma sensors to rapidly assess soil status and recovery in degraded East African agro-pastoral land
(Copernicus Publications, 2024-05-01)Soil resources in East African agro-pastoral lands are being rapidly depleted by erosion, threatening food, water and livelihood security. Here we explore the utility of innovation in portable gamma sensors to rapidly ... -
Radon Mass Exhalation Rates of Selected Building Materials in Tanzania
(Journal of Environment and Earth Science, 2015)This study aimed at determining the mass radon exhalation rate of Tanzania Portland cements and their raw materials for assessment of the radiological hazards due to use of those materials in residential construction. ... -
Rare earth elements and uranium in Minjingu phosphate fertilizer products: Plant food for thought
(ELSEVIER, 2024-08-01)Minjingu phosphate ore is Tanzania's sole domestic supply of phosphorus (P). The ore contains medium to high concentrations of naturally occurring P2O5 (20–35 %) and relevant concentrations of uranium and rare earth elements ... -
Reconstructing the Changes in Sedimentation and Source Provenance in East African Hydropower Reservoirs: A Case Study of Nyumba ya Mungu in Tanzania
(MDPI, 2021-08-08)This study aimed to reconstruct the sedimentation rates over time and identify the changing sources of sediment in a major hydropower reservoir in Tanzania, the Nyumba ya Mungu (NYM). Fallout 210Pb measurements were used ... -
Tracing the dominant sources of sediment flowing towards Lake Victoria using geochemical tracers and a Bayesian mixing model
(Springer Nature, 2023-02-14)Purpose Lake Victoria has been increasingly silting over the past decades, impacting water quality and loss of biodiversity. Sediment control strategies require information on the relative and absolute contributions of ... -
Uranium Dissemination with Phosphate Fertilizers Globally: A Systematic Review with Focus on East Africa
(MDPI, 2024-01-09)Growing concern has been expressed about uranium (U) accumulation in agricultural soils caused by the long-term application of mineral fertilizers. More than 80% of naturally occurring U transfers from phosphate rock ...
