    Ecosystem services in the Gariep basin
    (SUN PRESS, 2004) Bohensky, E.; Reyers, B.; Van Jaarsveld, A. S.; Fabricius, C.
    The Gariep Basin Millennium Ecosystem Assessment investigated the condition and trends of ecosystem services and human well-being in the Gariep basin from 1993 to 2003. The assessment features highlights from four local-scale assessments nested within the basin: Sehlabatebe, Great Fish River, Richtersveld, and Gauteng Province. Scenarios were constructed at both basin and local scales to depict possible alternative futures of ecosystem service supply and demand in 2030. Past, present, and possible future responses to change in ecosystem services were considered. Conducted with input and technical support from a User Advisory Group (UAG) comprising basin stakeholders, the assessment is aimed primarily at the international assessment community, decision-makers at national and provincial levels of government, research institutions, as well as the private sector and the general public.

    Conclusion : change in terrestrial and marine systems
    (AFRICAN SUN MeDIA, 2008) Chown, Steven L.; Froneman, P. William
    ENGLISH SUMMARY : The modern climate of the Prince Edward Islands has been described as one of the most oceanic and stable on earth (Schulze 1971; Van Zinderen Bakker 1978; le Roux 2008). Indeed, on the basis of the typically low daily amplitude of temperatures and their small variation between summer and winter, this characterization is correct. However, over both longer and shorter timescales, stability is something of a caricature. The islands have changed dramatically over the course of their history. Although much remains to be learned about the sequence of glaciation and volcanism on both islands (Boelhouwers et al. 2008), it is clear that they underwent considerable modification as a result of changing global climates and isostatic adjustment that was a consequence thereof.
