Prevalence of chronic obstructive pulmonary disease and associated factors among smallholder fish vendors along coastal areas in Tanzania
(BMC Pulmonary Medicine, 2023-08-02)Background In Tanzania little is known about how the respiratory system of small-holder fish vendors is affected by occupational exposure to biomass smoke and other associated factors. This study assessed the prevalence ... -
Conceptualization of groundwater-surface water interaction with evidence from environmental isotopes and hydrogeochemistry in lake Babati Basin in Northern Tanzania
(Elsevier, 2023-05)The holistic management of water resources is attainable with evidence-based planning constructed on reliable hydrological information. However, data paucity, especially in sub-Saharan Africa, leads to a significant knowledge ... -
Modeling and optimization of trivalent arsenic removal from wastewater using activated carbon produced from maize plant biomass: a multivariate experimental design approach
(Springer Nature Limited, 2023-06-24)Globally, both industrialized and developing nations struggle with the issue of water pollution due to heavy metals. Human life depends on water, and when it is contaminated with dangerous heavy metals like arsenic, people’s ... -
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 ... -
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 ... -
Influence of farmers’ socio-economic characteristics on nutrient flow and implications for system sustainability in smallholdings: a review
(Frontiers in Soil Science, 2023-04-14)The rise in global human population, coupled with the effects of climate change, has increased the demand for arable land. Soil fertility has been the most affected, among other things. Many approaches to soil fertility ... -
