    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    East African pastoral adaptation and vulnerability to climate variability and climate change is assessed, using data from decisionmaking processes and ecological data of the Maasai of Ngorongoro Conservation Area as an example. The paper uses integrated modeling, linking PHEWS, a...
  2. Adaptive management for complex communal rangelands in South Africa

    Adaptive management for complex communal rangelands in South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Many of the intransigent problems facing the world arise in complex systems. In this paper, I propose that communal rangelands in South Africa be recognised as complex social–ecological systems and that one of the reasons that development initiatives have had...
  3. Perceptions of climate change and barriers to adaptation amongst commonage and commercial livestock farmers in the semi-arid Eastern Cape Karoo

    Perceptions of climate change and barriers to adaptation amongst commonage and commercial livestock farmers in the semi-arid Eastern Cape Karoo

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Climate change is expected to adversely affect agriculture in South Africa. A rise in variable and unfavourable conditions is likely to surpass the limits of current coping mechanisms of farmers, compelling them to implement more resilient adaptive measures to decrease...

    Aggregate breakdown mechanisms as affected by soil texture and organic matter in soils dominated by primary minerals

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Soil aggregates breakdown mechanisms depend on soil properties such as texture, clay mineralogy and organic matter content. Little is known about the effect of soil properties on aggregate breakdown mechanisms in South African soils. The objective of this study was...
