Structural characterization of cassava linamarase-linamarin enzyme complex: an integrated computational approach
(Taylor & Francis Group, 2021-05-21)Cassava linamarase is a hydrolyzing enzyme that belongs to a glycoside hydrolase family 1 (GH1). It is responsible for breaking down linamarin to toxic cyanide. The enzyme provides a defensive mechanism for plants against ... -
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. ... -
An Evaluation of Sustainability Potential of Existing Septic Systems: A Fuzzy-Based Indexing Approach
(MDPI, 2022-05-05)In this study, a fuzzy-based indexing approach (FIA) is developed based on a conceptual framework regarding social, environmental, economic, and technical dimensions to evaluate the overall sustainability potential of ... -
Analysis of Macro- and Microplastics in Riverine, Riverbanks, and Irrigated Farms in Arusha, Tanzania
(Springer Nature Switzerland AG., 2021-11-16)Microplastics and macroplastics have been reported in different urban rivers and agricultural soil across the globe. However, the interlink between them has not been previously assessed. The present study evaluated the ... -
Strength and Durability Properties of Concrete Containing Pumice and Scoria as Supplementary Cementitious Material
(Hindawi, 2021-05-24)Concrete structures suffer serious deterioration under a corrosive environment. Consequently, the service life of these concrete structures is decreased and deteriorates under combined attack of sulphate and chlorides. ... -
Assessment of contamination level of a Tanzanian river system with respect to trace metallic elements and their fate in the environment
(IWA Publishing, 2022-04-01)The quality of water and sediments from a marginally-studied river was investigated with respect to As, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn including their fractionation behavior and environmental risk. Samples were collected ... -
Accounting for Seasonal Land Use Dynamics to Improve Estimation of Agricultural Irrigation Water Withdrawals
(MDPI, 2019-11-24)The assessment of water withdrawals for irrigation is essential for managing water resources in cultivated tropical catchments. These water withdrawals vary seasonally, driven by wet and dry seasons. A land use map is one ... -
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, ... -
Water Defluoridation Methods Applied in Rural Areas over the World
(IntechOpen Limited, 2022-06-23)Overexposure to fluoride (F) through drinking water is the most widespread water problem in the world, but it has now exacerbated due to rapid population growth rates, adverse climatic changes, and increasing levels of ... -
Building Climate Change Adaptation and Resilience through Soil Organic Carbon Restoration in Sub-Saharan Rural Communities: Challenges and Opportunities
(MDPI, 2021-10-02)Soil organic carbon (SOC) is widely recognised as pivotal in soil function, exerting important controls on soil structure, moisture retention, nutrient cycling and biodiversity, which in turn underpins a range of provisioning, ... -
Modeling and optimization of independent factors influencing lead(II) biosorption from aqueous systems: A statistical approach
(Elsevier, 2022-07)Lead, [Pb(II)] is a major hazardous contaminant that exists in the soil, surface, and groundwater as a result of human activities. It is carcinogenic in nature and causes damage to the liver, kidney, and bones as well as ... -
Soils, Science and Community ActioN (SoilSCAN): a citizen science tool to empower community-led land management change in East Africa
(IOPscience, 2022-08-02)Pastoralist communities worldwide face complex challenges regarding food and feed productivity. Primary production systems are under stress, nutritional choices are changing and the relationship between development and ... -
A Review of Methods for Removal of Ceftriaxone from Wastewater
(MDPI, 2022-08-02)The presence of pharmaceuticals in surface water and wastewater poses a threat to public health and has significant effects on the ecosystem. Since most wastewater treatment plants are ineffective at removing molecules ... -
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. ... -
The Influence of Fertilizers on the Behavior of Fluoride Fractions in the Alkaline Soil
(Elsevier, 2021-08-23)It has been established that fluoride bioavailability in the soil is defined by the form which it exists rather than the amount of total fluoride. In the soil, fluoride exist in different fractions such as water soluble ... -
A comprehensive review on the decontamination of lead(II) from water and wastewater by low-cost biosorbents
(Royal Society of Chemistry, 2022-04-12)The disadvantages of conventional methods in water and wastewater management including the demand for high energy consumption, the creation of secondary toxic sludge, and operation cost are much too high for developing ... -
Rainfall and temperature changes under different climate scenarios at the watersheds surrounding the Ngorongoro Conservation Area in Tanzania
(Elsevier, 2022-04)Considering the high vulnerability of Northern Tanzania to climate change, an in-depth assessment at the local scale is required urgently to formulate sustainable adaptations measures. Therefore, this study analyzed the ... -
The influence of gold mining on radioactivity of mining sites soil in Tanzania
(International Journal of Environmental Quality, 2022-02-17)The activity of 226Ra, 232Th and 40K in soil samples were measured by gamma spectrometry using high purity germanium detector. The study involved 40 samples from four divisions: 10 samples each were drawn from the control ... -
Performance analysis of a runner for gravitational water vortex power plant
(Wiley & Sons Ltd, 2022-02-14)Micro-hydropower can be used to meet the needs of both isolated and rural com munities for electricity. Due to its inexpensive initial investment, simple design, easy maintenance and low-head utilisation, the gravitational ... -
