  • Walking as method : toward methodological forthrightness and comparability in urban geographical research 
    Pierce, Joseph; Lawhon, Mary (Taylor & Francis, 2015-09)
    Qualitative urban geographical research should explicitly acknowledge insights gained from walking (the iterative exploration and observation of cities on foot), which enhances local literacy and enables researchers to ...
  • Waste disposal practices in low-income settlements of South Africa 
    Haywood, Lorren Kirsty; Kapwata, Thandi; Oelofse, Suzan; Breetzke, Gregory Dennis; Wright, Caradee Yael (MDPI Publishing, 2021-08-02)
    Domestic solid waste is rapidly increasing due to accelerated population growth and urbanization. Improper waste disposal poses potential health risks and environmental concerns. Here, we investigated waste disposal ...
  • Water erosion risk assessment in South Africa : a proposed methodological framework 
    Le Roux, J.J. (Jacobus Johannes); Sumner, P.D. (Paul) (Wiley-Blackwell, 2013-12)
    With the increase in human impacts on the environment, especially in terms of agricultural intensification and climate change, erosion processes need to be assessed and continually monitored. In many countries, ...
  • Webdiens vir tematiese kartering 
    Rautenbach, Victoria (AOSIS Open Journals, 2013)
    The goal of the research is to evaluate proprietary software and solutions suggested by other researchers for the implementation of a mechanism for the production of thematic maps on desktop and web applications, as well ...
  • Weed detection in rainfed maize crops using UAV and planetscope imagery 
    De Villiers, Colette; De Villiers, Colette; Mashaba-Munghemezulu, Zinhle; Chirima, George J.; Tesfamichael, Solomon G. (MDPI, 2023-09-07)
    Weed invasion of crop fields, such as maize, is a major threat leading to yield reductions or crop right-offs for smallholder farming, especially in developing countries. A synoptic view and timeous detection of weed ...
  • What lies beneath : detecting sub-canopy changes in savanna woodlands using a three-dimensional classification method 
    Fisher, J.T. (Jolene); Witkowski, E.T.F. (Ed); Erasmus, Barend Frederik Nel; Mograbi, P.J. (Penelope); Asner, G.P. (Gregory); Van Aardt, J.A.N.; Wessels, K.J. (Konrad); Mathieu, Renaud (Wiley, 2015-07)
    QUESTION : Increasing population pressure, socio-economic development and associated natural resource use in savannas are resulting in large-scale land cover changes, which can be mapped using remote sensing. Is a ...
  • Where have all the flowers gone? – Changing climate, seasons and weather and the challenges and opportunities for public health research 
    Sweijd, Neville; Wright, Caradee Yael (Medpharm Publications, NISC (Pty) Ltd and Cogent, Taylor and Francis Group, 2018)
    Since the United Nations Framework Convention on Climate Change (UNFCCC) negotiations produced the Paris Agreement1 of December 2015, despite its subsequent notorious political challenges, the zeitgeist of global warming ...
  • Wind power variability during the passage of cold fronts across South Africa 
    Dalton, Amaris; Bekker, Bernard; Kruger, Andries C. (Energy Research Centre, University of Cape Town, 2019-08)
    Wind is a naturally variable resource that fluctuates across timescales and, by the same token, the electricity generated by wind also fluctuates across timescales. At longer timescales, i.e., hours to days, synoptic-scale ...
  • WMO assessment of weather and climate mortality extremes : lightning, tropical cyclones, tornadoes, and hail 
    Cerveny Randall S.; Bessemoulin, Pierre; Burt, Christopher C.; Cooper, Mary Ann; Cunjie, Zhang; Dewan, Ashraf; Finch, Jonathan; Holle, Ronald L.; Kalkstein, Laurence; Kruger, Andries C.; Lee, Tsz-Cheung; Martinez, Rodney; Mohapatra, M.; Pattanaik, D.R.; Peterson, Thomas C.; Sheridan, Scott; Trewin, Blair; Tait, Andrew; Abdel Wahab, M.M. (American Meteorological Society, 2017-07)
    A World Meteorological Organization (WMO) Commission for Climatology international panel was convened to examine and assess the available evidence associated with five weather-related mortality extremes: 1) lightning ...
  • A yield gap analysis to assess vulnerability of commercial sugarcane to climatic extremes in southern Africa 
    Ngcobo, S.I.; Hill, T.R.; Jewitt, G.; Archer, Emma Rosa Mary (Elsevier, 2023-12)
    Sugarcane yields have steadily declined across southern Africa for the past 25 years and, despite research into the causes, there has been limited progress in addressing these trends. This study developed a methodology ...
