- Description: Terracettes and turf-banked terraces exist at Tiffindell Ski Resort in the Drakensberg of the Province of the Eastern Cape at altitudes between 2750 m and 2880 m on slopes of between 15°and 26°. Ice lenses and interstitial ice exist within turf-banked terraces in winter. During post-winter thaws, soil moisture reaches saturation in at least the upper part of the regolith in which turf-banked terraces occur. These terraces move downslope under the influence of gelifluction (which is essentially a combination of frost creep and solifluction). Terracettes appear to move as a result of frost creep, processes associated with needle ice, and slope wash. Both turf-banked terraces and terracettes are part of the periglacial environment and are active under present climatic conditions at Tiffindell.

- Description: Economic impact studies have been used to measure the value of a variety of public and mixed goods, such as arts festivals, sports facilities and educational institutions, partly to motivate for public funds. The attraction of this sort of study rests largely on the fact that it produces a quantifiable monetary measure of the value of a project as opposed to a less easily valued qualitative study. “Public officials, boosters and the media accept the ‘quantifiable’ which appears to represent reality in order to justify a desired project” (Johnson and Sack 1996:370).
