Large-scale land acquisitions exacerbate local farmland inequalities in Tanzania
(National Academy of Sciences, 2023-07-31)Land inequality stalls economic development, entrenches poverty, and is associated with environmental degradation. Yet, rigorous assessments of land-use interventions attend to inequality only rarely. A land inequality ... -
Effect of groundwater residence time on geogenic fluoride release into groundwater in the Mt. Meru slope area, Tanzania, the Great Rift Valley, East Africa
(Elsevier Ltd., 2023)People living in the Great Rift Valley in East Africa suffer from fluorosis resulting from their consumption of groundwater. This paper shows that geogenic fluoride contamination in a natural water system has changed in ... -
Are electric vehicles economically viable in sub-Saharan Africa? The total cost of ownership of internal combustion engine and electric vehicles in Tanzania
(Elsevier, 2023-09)The prevalence of internal combustion engine vehicle (ICEV) fleets globally has resulted in various environmental issues, such as the emissions of greenhouse gases, reliance on imported petroleum products, significant ... -
Fuzzy modelling on the depletion of forest biomass and forest-dependent wildlife population
(Elsevier, 2023-09-01)This paper presents a system of non-linear differential equations describing the depletion of forest biomass and forest-dependent wildlife population caused by human population and its associated activities. The model ... -
Mathematical model to study the impact of anthropogenic activities on forest biomass and forest-dependent wildlife population
(Springer Berlin Heidelberg, 2023-07-21)This paper proposes and analyses a nonlinear mathematical model to study the impact of anthropogenic activities on forest biomass and forest-dependent wildlife populations using a system of differential equations. It is ... -
Applicability of bio-adsorbents synthesized from maize/corn plant residues for heavy metals removal from aquatic environments: an insight review
(EQA-International Journal of Environmental Quality, 2023-07-14)The underutilization of agricultural waste products in recent years has resulted in environmental issues owing to improper disposal. As a result, heavy metals removal from aqueous systems utilizing sorbent materials produced ... -
Adsorption and desorption ability of divalent mercury from an interactive bicomponent sorption system using hybrid granular activated carbon
(Springer International Publishing, 2023-09)The sequestration of heavy metals from multicomponent sorption media has become critical due to the noxious effects of heavy metals on the natural environment and subsequently on human health as well as all life forms. The ... -
Hydrogeochemical similarities and groundwater-surface water interactions for the karst hydrological system of northwest Rwanda
(Springer International Publishing, 2023-08)The groundwater of karst environments is vulnerable to pollution due to its heterogeneous nature and can be completely depleted due to its strong connection to surface water when predominantly driven by natural and ... -
What proportion counts? Disaggregating access to safely managed sanitation in an emerging town in Tanzania
(MDPI, 2019-09-10)Sustainable Development Goal (SDG) 6.2 sets an ambitious target of leaving no-one without adequate and equitable sanitation by 2030. The key concern is the lack of local human and financial capital to fund the collection ... -
Modelling the Impact of Human Population and Its Associated Pressure on Forest Biomass and Forest-Dependent Wildlife Population
(Hindawi Limited, 2023-01-12)Mathematical models have been widely used to explain the system originating from human-nature interaction, investigate the impacts of various components, and forecast system behaviour. This paper provides a profound reference ... -
Community-based Forest Landscape Restoration (FLR): Determinants and policy implications in Tanzania
(Elsevier, 2021-10)Forest landscape restoration (FLR) has gained global scientific and political attention in recent times, with many sub-Saharan African countries committing to restoration targets. Despite the commitments, there is a dearth ... -
Diarylheptanoid Glycosides of Morella salicifolia Bark
(NM-AIST, 2017-12-19)A methanolic extract of Morella salicifolia bark was fractionated by various chromatographic techniques yielding six previously unknown cyclic diarylheptanoids, namely, 7-hydroxymyricanol 5-O-β-D-glucopyranoside (1), ... -
Use of 210Pb and 137Cs radionuclides as simple method of estimating sedimentation rates on reservoir
(Egyptian Society of Nuclear Sciences and Applications (ESNSA), 2023-01)Reservoirs are important for flood control, production of hydroelectric power, fishing, water harvesting and storage. Climate is changing, population and anthropogenic activities are increasing which increase sedimentation ... -
What influences individuals to invest in improved sanitation services and hygiene behaviours in a small town? A formative research study in Babati, Tanzania
(Public Library of Science, 2022-07-21)Sub-Sahara African countries face immense challenges in ensuring adequate sanitation and hygiene behaviours to the rapidly growing populations. Attempts to address these challenges require empirical evidence to inform ... -
Assessment of variation in marginal productivity value of water in paddy farming systems in times of water stress
(MDPI, 2022-10-29)Global projections show that increases in agriculture water productivity (AWP) by 30 and 60% in rain-fed and irrigated agriculture, respectively, are required to ensure food security in the period 2000–2025. In sub-Saharan ... -
Does variation in plant diversity and abundance influence browsing intensity in black rhinos?
(African Journal of Ecology, 2023-03-17)Variations in forage availability, selection and preferences can lead to intense foraging competition and depletion of food consequently lowering diet quality and population performance of black rhino species. This study ... -
