    Landuse and landcover change assessment in the Upper Runde sub-catchment, Zimbabwe and possible impacts on reservoir sedimentation
    (Physics and Chemistry of the Earth, 2022) Dube, Timothy; Kusena, Winmore; Chemura, Abel; Nicolau, Melanie. D; Marambanyika, Thomas
    This work assesses land cover changes on the Upper Runde sub-catchment, Zimbabwe, and associated effects on sedimentation rates and risks. The model was implemented using the common Geographic Information Systems tools. To achieve this objective, mean annual and monthly rainfall, as well as sediment data, were used (December 2016 and April 2017). Land use and land cover changes were assessed using time-series Landsat data acquired between the years 2000 and 2016. The Revised Universal Soil Loss (RUSLE) model was used to model sedimentation rates in the catchment

    Local community attitudes and perceptions towards benefits and challenges associated with biodiversity conservation in Blouberg Nature Reserve, South Africa
    (Journal of Ecology, 2022) Dube, Timothy; Rampheri, Mangana B; Shoko, Cletah; Marambanyika, Thomas; Dhau, Inos
    This study assessed the benefits and challenges associated with local community involvement in biodiversity conservation in the Blouberg Nature Reserve (BNR) of South Africa. To achieve this, a descriptive research design was used in the study. Three hundred and thirty-five households from four villages scattered around the nature reserve were selected using a stratified systematic sampling procedure to participate in a household questionnaire survey. The BNR Manager was purposefully selected for an in- depth structured interview so that an overview of socio-economic benefits and challenges to the community from the park's perspective could be known. Field data collection was conducted during the month of June 2019.
