Climate and anthropogenic footprints implications on the surface and groundwater dynamics on the southern slopes of Mount Kilimanjaro, Tanzania
(NM-AIST, 2021-10)Climate and land use/cover changes impact water resources all over the world. This study aimed at developing a conceptual understanding and management of the impacts of present and future climate change and human ... -
Contamination assessment and optimization of coagulation-flocculation-sedimentation water treatment process for Kou river in northern Tanzania
(NM-AIST, 2022-06)The Babati Urban Water Supply and Sanitation Authority (BAWASA) in northern Tanzania supplies water from the Kou River to Magugu town for domestic purpose, where its Fe (3.64 mg/L) and turbidity (87 NTU) concentrations ... -
Diversity and quantity of macro-and microplastics in irrigation farms sourcing water from an urban river: a case of Arusha Tanzania
(NM-AIST, 2021-10)Increased concentration of plastics in urban rivers and agricultural farms causes degradation of river system functionality and reduces the productivity of agricultural soils, respectively. This study assessed the ... -
Evaluation of recharge areas of Arusha aquifer, northern Tanzania: application of water isotope tracers
(NM-AIST, 2022-01)In Arusha urban, northern Tanzania, groundwater contributes about 80% of the water supply. However, elevated fluoride levels and evidence of anthropogenic pollution have been reported in the groundwater around Mount ... -
Impacts of irrigation water quality, associated soils characteristics and on-farm practices on paddy yields
(NM-AIST, 2022-07)In this study, the impacts of irrigation water quality, soil characteristics and on-farm practices on paddy yields were investigated. Standard spectroscopy and spectrometry methods were used to analyze irrigation water ... -
Influence of land use change on nitrate sources and pollutant enrichment in surface and groundwater of a growing urban areas
(NM-AIST, 2022-07)In the present study, three-year (1997, 2008 and 2017) satellite images as well as different hydro chemical parameters, nitrogen and oxygen isotopic composition of nitrate were used to examine the impacts of land use and ... -
Kinetics and optimization modeling of Fenton-mediated photocatalysis of dye effluent with novel PANI/AK-TiO2 nanocomposites
(Springer Berlin Heidelberg, 2024-04-05)The quest for the application of a high solar-photon sensitive photocatalysts for rapid photodegradation of recalcitrant dye molecules with deleterious environmental impacts remains a major setback for the adoption of ... -
Optimization of sub- and supercritical water gasification of rice husk enhanced with iron-doped alkaline-earth catalysts
(NM-AIST, 2022-05)Biomass is a promising renewable energy source widely available worldwide, particularly in developing countries where clean and affordable energy is a major problem. Biomass gasification is an attractive technology ... -
The potential of water resources contamination around a large-scale gold mine
(NM-AIST, 2022-05)This study used the hydro-chemical properties and isotopic signatures of water to understand the main sources of deterioration of water quality around the North Mara gold mine in Tarime District, Mara Region. The ... -
Representation of seasonal land use dynamics in SWAT+ for improved assessment of blue and green water consumption
(Hydrology and Earth System Sciences, 2022-08-29)In most (sub)-tropical African cultivated regions, more than one cropping season exists following the (one or two) rainy seasons. An additional cropping season is possible when irrigation is applied during the dry season, ... -
Simulation and performance analysis of municipal solid waste gasification in a novel hybrid fixed bed gasifier
(NM-AIST, 2022-06)Municipal Solid Waste (MSW) is a main challenge to municipalities in developing countries due to the increase in its production caused by technology development, community culture, population growth, and urbanization. ... -
Strength and durability properties of concrete blended with pumice and scoria under combined attack of sulphate and chloride
(NM-AIST, 2021-11)Concrete structures suffer serious deterioration under corrosive environment. Consequently, the safety of these concrete structures is decreased. The influence of natural pumice (NP) and natural scoria (NS) as supplementing ... -
Structural and biophysical characterization of cassava linamarase and the role of solvents on linamarin’s properties: a computational study
(NM-AIST, 2022-06)Linamarase and linamarin mainly from cassava have many applications ranging from food, environmental to the medical industry. To better explore the potential of this enzyme and its substrate, one needs to understand ... -
Water use and crop water productivity in farmer managed irrigation schemes across agro ecological zones of usa river catchment
(NM-AIST, 2021-11)The Usa River Catchment is the potential area dealing with traditional irrigated agriculture. This study aims to estimate the amount of water abstracted for and yield that reflect water values to enhance crop water ...
