Adapting the Dyna-CLUE model for simulating land use and land cover change in the Western Cape Province

Author: Tizora, P ; Le Roux, Alize ; Mans, Gerbrand G ; Cooper, Antony K Date: Sep 2018 Models which integrate and evaluate diverse factors of Land Use and Land Cover (LULC) change can be used to guide planners in making more informed decisions and achieving a balance between urban growth and preservation of the natural environment. ...

An assessment of remote sensing-based drought index over different land cover types in southern Africa

Author: Marumbwa, FM ; Cho, Moses A ; Chirwa, PW Date: Jul 2020 An understanding of drought and land cover interaction plays a crucial role in vegetation vulnerability studies and land use planning. However, there is paucity of information on drought, land cover and land use interaction in southern Africa. ... Read more
Comparing three spaceborne optical sensors via fine scale pixel-based urban land cover classification products

Author: Breytenbach, Andre ; Eloff, C ; Pretorius, E Date: Aug 2013 Accessibility to higher resolution earth observation satellites suggests an improvement in the potential for fine scale image classification. In this comparative study, imagery from three optical satellites (WorldView-2, Pléiades and RapidEye) ... Read more
Effects of global change on tropical ecosystems

Author: Scholes, RJ ; Van Breemen, N Date: Sep 1997 Alteration of land use will continue to be the dominant driver of environmental change in the tropics for the next several decades. It can take the form of fundamental vegetation cover transformation, or of intensification of existing land ... Read more
Effects of land use change on streamflow and stream water quality of a coastal catchment

Author: Petersen, Chantel R ; Jovanovic, Nebojsa ; Le Maitre, David C ; Grenfell, MC Date: Jan 2017 This study aimed to link land cover/use change to water quality in an important water supply coastal catchment. The approach followed a spatial and temporal analysis of historical catchment land use change to assess how changes influenced ... Read more
Ensemble classification for identifying neighbourhood sources of fugitive dust and associations with observed PM10

Author: Khuluse-Makhanya, Sibusisiwe A ; Stein, A ; Breytenbach, Andre ; Gxumisa, Athi A ; Dudeni-Tlhone, Nontembeko ; Debba, Pravesh Date: Oct 2017 In urban areas the deterioration of air quality as a result of fugitive dust receives less attention than the more prominent traffic and industrial emissions. We assessed whether fugitive dust emission sources in the neighbourhood of an air ... Read more
Land use land cover change and the comparative impact of co-management and government-management on the forest cover in Malawi (1999-2018)

Author: Goede, MF ; Cho, Moses A ; Chirwa, W ; Geldenhuys, CJ Date: Jan 2020 Miombo Woodland is the major Land use/land cover with important ecological functions in Africa. In Malawi, government-management was designed to manage Woodlands. However, when illegal activities continued, Participatory Forest Management ... Read more
Rapid land cover map updates using change detection and robust random forest classifiers

Author: Wessels, Konrad J ; Van den Bergh, F ; Roy, DP ; Salmon, BP ; Steenkamp, Karen C ; MacAlister, B ; Swanepoel, D ; Jewit, D Date: 2016 The paper evaluated the Landsat Automated Land Cover Update Mapping (LALCUM) system designed to rapidly update a land cover map to a desired nominal year using a pre-existing reference land cover map. The system uses the Iteratively Reweighted ... Read more
Unsupervised land cover change detection: meaningful sequential time series analysis

Author: Salmon, BP ; Olivier, JC ; Wessels, Konrad J ; Kleynhans, W ; Van den Bergh, F ; Steenkamp, Karen C Date: Jun 2011 An automated land cover change detection method is proposed that uses coarse spatial resolution hyper-temporal earth observation satellite time series data. The study compared three different unsupervised clustering approaches that operate ... Read more
