  • Le Maitre, David C; Versfeld, DB (Elsevier Science BV, 1997-06)
    The relationships between forest stand structure, growth and evaporation were analysed to determine whether forest evaporation can be estimated from stand growth data. This approach permits rapid assessment of the potential ...
  • Scott, DF; Gush, Mark B (United Nations Educational, Scientific and Cultural Organization (UNESCO), 2017-04)
    South Africa is a semi-arid country with a very limited area of natural forest. The early colonial governments encouraged the establishment of plantations to supply wood for local uses, and South Africa consequently has a ...
  • van der Zel, DW (National Scientific Programmes Unit: CSIR, 1988)
    Even after 300 years of indigenous forest protection as well as 100 years of plantation forestry, no forestry map of South Africa was available. The development and availability of LANDSAT images in the early 1970s opened ...

  • Scott, DF; Le Maitre, David C; Fairbanks, DHK (Water Research Commission, 1998-07)
    Forestry is an important sector of industry in South Africa but the growing of timber places significant demands on the available water resources. Yet, a ready source of information on the extent, and probable hydrological ...
  • Hamman, J (IIED & CSIR, 2000)
    The IIED and CSIR have embarked on a joint study on Instruments for Sustainable Private Sector Forestry. In terms of this study, a sub-study on the experience of persons involved in the certification process was commissioned. ...
  • Khosa, M (IIED & CSIR, 2000)
    The outsourcing of forestry activities over the past decade has created an industry with an annual turnover of R600 million and 35000 employees (Edwards, 2000). During the past decade forestry companies have switched from ...
  • Naidoo, Sasha; Davis, C; Archer van Garderen, Emma RM (Food and Agriculture Organization of the United Nations Rome, 2013-09)
    This paper provides an analysis of the implications of climate change for forests and rangelands in southern Africa. The extent of the resources and their economic and social functions and drivers of change is outlined. ...
  • Ngassam, EK; Watson, BW; Kourie, DG (2010-08)
    With this poster, the authors on the denotational semantics of algorithms to suggest an abstraction of a string recognizer. The abstraction provides a unified formalism for representing FA-based string recognizers as an ...
