Environmental factors and non-chemical methods to suppress growth of the invasive plant Gutenbergia cordifolia
(Elsevier, 2023-08-01)Little is known about preferred environmental conditions and non-chemical control of invasive Gutenbergia cordifolia. We assessed the effects of different A. annua crude extract concentrations, synthetic herbicide (glyphosate), ... -
Conservation and Management Challenges Facing a Medicinal Plant Zanthoxylum chalybeum in Simanjiro Area, Northern Tanzania
(MDPI, 2020-05-19)The information on the medicinal use, availability, challenges, and future conservation strategies for the medicinal plant Zanthoxylum chalybeum were gathered by using a semi-structured questionnaire, focused group ... -
Effects of Restoration Techniques on Plant Diversity and Forage Biomass in Areas Invaded by Prosopis juliflora
(International Journal of Advances in Scientific Research and Engineering, 2021-12)Prosopis juliflora, an invasive plant worldwide causes major threats by destructing natural ecosystem and limits provisioning of ecosystem services in the invaded areas. Attempts to manage the species and restore invaded ... -
Connectivity between land, water, and people: integrating process concepts and assessment evidence across disciplines for co-design of soil erosion solutions
(Authorea, 2020-04-20)Soil resources in East Africa are being rapidly depleted by erosion, threatening food-, water- and livelihood security in the region. Here we demonstrate how integration of evidence from natural and social sciences has ... -
Conservation of forest biomass and forest–dependent wildlife population: Uncertainty quantification of the model parameters
(Elsevier, 2023)The ecosystem is confronted with numerous challenges as a consequence of the escalating human population and its corresponding activities. Among these challenges lies the degradation of forest biomass, which directly ... -
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 ... -
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 ... -
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 ... -
