  1. Estimating plot-level forest structural attributes using high spectral resolution ASTER satellite data in even-aged <em>Eucalyptus</em> plantations in southern KwaZulu-Natal, South Africa

    Estimating plot-level forest structural attributes using high spectral resolution ASTER satellite data in even-aged <em>Eucalyptus</em> plantations in southern KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    This study assessed the suitability of both visible and shortwave infrared of ASTER reflectance bands and various vegetation indices for estimating forest structural attributes of Eucalyptus species. The study was conducted in even-aged monoculture plantations of E. grandis and E...
  2. Image-based reflectance conversion of ASTER and IKONOS imagery as precursor to structural assessment of plantation forests in KwaZulu-Natal, South Africa

    Image-based reflectance conversion of ASTER and IKONOS imagery as precursor to structural assessment of plantation forests in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Reflectance-converted imagery is a requirement for establishing temporally robust remote sensing algorithms, given the reduction of time-specific atmospheric effects. Thus, in this study image-based atmospheric correction methods for ASTER and IKONOS imagery for retrieving surface reflectance of plantation forests in...
  3. Predicting soil nitrogen content using narrow-band indices from <em>Eucalyptus grandis</em> canopies as proxy

    Predicting soil nitrogen content using narrow-band indices from <em>Eucalyptus grandis</em> canopies as proxy

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Optimal fertiliser applications for sustainable forest stand productivity management, whilst protecting the environment, is vital. This study estimated soil nitrogen content using leaf-level narrow-band vegetation indices derived from a hand-held 350-2 500 nm spectroradiometer. Leaf-level spectral data were collected and subjected...
  4. Knowledge, attitudes and practices in the control and prevention of malaria in four endemic provinces of Zambia

    Knowledge, attitudes and practices in the control and prevention of malaria in four endemic provinces of Zambia

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    This study sought to determine malaria knowledge levels, attitudes and practices of the communities in four malaria endemic provinces of Zambia. A cross-sectional survey on knowledge, attitude and practices (KAP) on malaria transmission, prevention and control was conducted among 584...
  5. Forest structural assessment using remote sensing technologies: an overview of the current state of the art

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    The Forestry and Forest Products Research Centre (CSIR), University of KwaZulu-Natal and MONDI Business Paper have recently embarked on a remote sensing cooperative. The primary focus of this cooperative is to explore the potential benefits associated with using remote sensing...
