    The socioeconomic status of the non-timber forest product subsector in Swaziland

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    A wide spectrum of non-timber forest products (NTFPs) generally has a remarkable contribution to the household economy in rural areas. Most communities make a living either through their domestic or commercial use. The objective of this study was to review...
  4. Land Valuation with a Limited Planning Horizon

    Item type: Journal Article • Journal: South African Forestry Journal
    The forestry industry in South Africa operates within a dynamic environment. Rotations are relatively short, land use conversion takes place regularly and company ownership changes frequently. Foresters in the private sector are therefore reluctant to use Land Expectation Value with...
  5. Problems in implementing improved range management on common lands in Africa: An Australian perspective

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Rangeland/livestock development in Africa is reviewed and lessons learnt from successes and failures are noted. Pastoral communities have developed risk aversion strategies to survive in the harsh environment and fragile ecology of rangeland areas. With advances in infrastructure (transport, water...
  6. The optimization of nitrogen and phosphorus application to cultivated <em>Digitaria eriantha</em> ssp. <em>eriantha</em> pasture

    The optimization of nitrogen and phosphorus application to cultivated <em>Digitaria eriantha</em> ssp. <em>eriantha</em> pasture

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A production function is derived and calibrated for Digitaria eriantha hay production in the Highveld region of the RSA. A procedure is described that optimizes this function for nitrogen and phosphorus application rates within economic and risk constraints at different...
  7. Plant resistance × environment interaction: Perspectives on yield losses caused by the maize stalk borer, <em>Busseola fusca</em> (Fuller)

    Plant resistance × environment interaction: Perspectives on yield losses caused by the maize stalk borer, <em>Busseola fusca</em> (Fuller)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Experimental maize hybrids with various levels of resistance to the maize stalk borer, Busseola fusca (Fuller), were evaluated at different infestation levels during seasons of favourable and unfavourable rainfall. Limited plant resistance sufficed to reduce plant damage and yield losses...

    Valuing preferences for wetland preservation: A Wakkerstroom case study

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Wetland loss rates remain high as the full value of wetland services is understated. This is partly due to the benefits of wetland preservation (nonā€use) being unpriced, as they are not traded in markets. These benefits are reflected by option,...

    The Effect of Real Price Changes on the Valuation of Timber Plantations

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The well-established method which is applied in South Africa to determine the value of timber plantations ignores real or relative price changes. The omission of real price changes from a plantation valuation can seriously understate or overstate the true value...
