    The CSIR celebrated its 60th anniversary in 2006 by taking a long, hard look at its continuing role in South Africa. This paper was written by the CSIR Fellows, at the invitation of the Department of Science and Technology, ...
  • Otter, LB; Scholes, RJ; Dowty, P; Privette, J; Caylor, K; Ringrose, S; Mukelabai, M; Frost, P; Hanan, N; Totolo, O; Veenendaal, EM (Academy of Science of South Africa, 2002-03)
    The Southern African Regional Science Initiative (SAFARI 2000) involved two wet season and one dry season field campaigns. This paper reports on the wet season campaigns. The first was conducted at five sites along the ...
  • Scholes, RJ; Savage, MJ (National Scientific Programmes Unit: CSIR, 1989)
    The parameters used to describe the flow of water, and energy to a lesser extent, through the soil-plant-atmosphere continuum are reviewed and the techniques used for estimating their values contrasted. The measurements ...
  • Scholes, RJ; Archer, SR (Annual Reviews Inc, 1997)
    Savannas occur where trees and grasses interact to create a biome that is neither grassland nor forest. Woody and gramineous plants interact by many mechanisms, some negative (competition) and some positive (facilitation). ...

    The Kalahari sand sheet occupies 2.5 million ha in southern Africa. It is an area with relatively similar deep Aeolian soils, and a strong south to north gradient in rainfall, from 200 to 1000 mm mean annual precipitation ...
  • Scholes, RJ (Academy of Science of South Africa, 2002-09)
    This paper describes a simple, quick, non data-intensive quantitative approach for sorting certain types of environmental issues into those that are unlikely to be problems; those likely to be problems; and those requiring ...

    The Kalahari Transect is one of several International Geosphere-Biosphere Programme (IGBP) transects designed to address global change questions at the regional scale, in particular by exploiting natural parameter gradients ...
  • Archibald, SA; Roy, DP; Van Wilgen, BW; Scholes, RJ (Blackwell Publishing, 2009-03)
    The factors controlling the extent of fire in Africa south of the equator were investigated using moderate resolution (500 m) satellite-derived burned area maps and spatial data on the environmental factors thought to ...
