  1. Climate change and desertification in South Africa—science and response

    Climate change and desertification in South Africa—science and response

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Despite significant attention paid to desertification and climate change in the last few decades, interactions between the phenomena, as well as implications thereof, have received less of a focus. Such a trend is particularly marked in the science– policy arena,...
  2. The impact of land use on woody plant cover and species composition on the Grahamstown municipal commonage: implications for South Africa's land reform programme

    The impact of land use on woody plant cover and species composition on the Grahamstown municipal commonage: implications for South Africa's land reform programme

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Using an analysis of aerial photographs from 1942, 1985 and 2004 we assessed the impact of changing land tenure and land-use regimes on the cover of thicket vegetation on the Grahamstown commonage. Land-use impacts were examined by comparing plant species...
  3. Bird diversity and land use on the slopes of Mt Kilimanjaro and the adjacent plains, Tanzania

    Bird diversity and land use on the slopes of Mt Kilimanjaro and the adjacent plains, Tanzania

    Item type: Journal Article • Journal: African Zoology
    This study of bird distribution in the main land-use categories of the slopes of Mt Kilimanjaro, Tanzania, aims at understanding potential impacts of the land-use changes on birds. A land-use map of the study area was derived from a Landsat...
  4. Long-term landscape changes in vegetation structure: fire management in the wetlands of KwaMbonambi, South Africa

    Long-term landscape changes in vegetation structure: fire management in the wetlands of KwaMbonambi, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    In wetlands the effects of fire on vegetation dynamics are somewhat uncertain. A change detection analysis in the herbaceous wetlands of KwaMbonambi, South Africa, which were subject to frequent fires, revealed that in 1937 the study area comprised grassland (69%),...
  5. A review of carbon dynamics and assessment methods in the miombo woodlands

    A review of carbon dynamics and assessment methods in the miombo woodlands

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Provision of accurate carbon (C) measurements and analysis are critical components in quantification of C stocks. The objectives of this review were to (1) compile and synthesise current knowledge of available methods for C stock estimation, (2) examine socio-economic drivers...
  6. Deforestation since independence: a quantitative assessment of four decades of land-cover change in Malawi

    Deforestation since independence: a quantitative assessment of four decades of land-cover change in Malawi

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Land cover has changed rapidly across the tropics over the past century; however, detailed historical information describing the extent and possible drivers of such change is widely lacking. Here, we constructed a history of land-cover change at the district level...
  7. Long-term changes in land use, land cover and vegetation in the Karoo drylands of South Africa: implications for degradation monitoring<xref ref-type="fn" rid="FN0000"/>

    Long-term changes in land use, land cover and vegetation in the Karoo drylands of South Africa: implications for degradation monitoring<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We used several large data sets at a range of temporal and spatial scales to document the land-use/land-cover change (LULCC) dynamics of the semi-arid Succulent Karoo and Nama-Karoo biomes of South Africa. More than 95% of the Karoo is comprised...

    Reflections on the Karoo Special Issue: towards an interdisciplinary research agenda for South Africa’s drylands<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We begin this essay with reflections on major research themes highlighted by the Karoo Special Issue (KSI). These include concerns over land-use change, long-term monitoring, climate change, governance and the need for more interdisciplinary research. We also identify some of...
  9. Evaluating Forestry Land During Inflationary Times

    Item type: Journal Article • Journal: South African Forestry Journal
    The Land Expectation Value criterion has been used since 1849 to calculate the value of forestry land. It was, however, developed in a static financial environment, and is no longer suitable for land valuation in today's dynamic financial environment. This...
  10. Comparison of <em>Eucalyptus grandis</em> Provenances and Seed Orchards in a Frost Frequent Environment

    Item type: Journal Article • Journal: South African Forestry Journal
    An international provenance trial of Eucalyptus grandis was established in southern Florida in 1980 and measured for growth and frost-tolerance through 8,8 years. The trial compared 20 Australian provenances 1) among themselves and 2) with seed orchard stock from Florida...
