Richtersveld Cultural <strong>and</strong> Botanical L<strong>and</strong>scape World Heritage Site Nomination 92<br />

focused on youth, such as <strong>the</strong> annual Youth Summit in <strong>the</strong> Conservancy, have also<br />

contributed to awareness about <strong>the</strong> importance of conserving <strong>and</strong> retaining <strong>the</strong><br />

environmental <strong>and</strong> <strong>cultural</strong> heritage objects, including plant an animal species.<br />

Additional awareness campaigns are planned for 2006 <strong>and</strong> 2007.<br />

As described in Section 3.d. (Integrity <strong>and</strong> Au<strong>the</strong>nticity), mining development does<br />

not pose a threat to <strong>the</strong> site. In addition to <strong>the</strong> zoning restrictions which are currently<br />

written into <strong>the</strong> municipality’s Integrated Development Plan (IDP) <strong>and</strong> <strong>the</strong><br />

Management Plan of <strong>the</strong> Conservancy <strong>and</strong> forthcoming legal restrictions in <strong>the</strong><br />

declaration of <strong>the</strong> Heritage Area, <strong>the</strong>re are significant environmental restrictions<br />

which prevent diamond mining from occurring in <strong>the</strong> Conservancy, as well as its<br />

Buffer Zones, as specified in more detail in Section 3.d (Integrity <strong>and</strong> Au<strong>the</strong>nticity).<br />

4.b (ii) Environmental Pressures<br />

Seasonal drought is an occurrence in <strong>the</strong> Conservancy <strong>and</strong> one which is inherently<br />

part of <strong>the</strong> region’s climate which has led to <strong>the</strong> diversity of plants which one finds in<br />

<strong>the</strong> Conservancy. These seasonal droughts are coped with by local herders by <strong>the</strong><br />

movement of herds throughout <strong>the</strong> Conservancy area. The Conservancy also<br />

encompasses two rainfall zones, summer <strong>and</strong> winter, which allows drought-hit<br />

areas to recover <strong>and</strong> remain without livestock for several months off <strong>the</strong> year. The<br />

region despite bouts of dry wea<strong>the</strong>r receives fairly reliable rainfall, especially for <strong>the</strong><br />

desert area.<br />

Studies of <strong>the</strong> impacts of climate change on <strong>the</strong> Richtersveld flora are being carried<br />

out. Particularly, <strong>the</strong> Aloe dichotoma <strong>and</strong> Aloe pillansii are considered under threat<br />

from global warming. Several areas where A. dichotoma were formerly abundant<br />

are now devoid of young plants, leading scientists to believe that <strong>the</strong> rise in<br />

temperature <strong>and</strong> <strong>the</strong> resultant effect on changes in rainfall patterns are preventing<br />

young plants from surviving. This phenomenon is likely to be happening also to A.<br />

pillansii, a significantly rarer aloe of which almost <strong>the</strong> entire population occurs in <strong>the</strong><br />

Conservancy. Fur<strong>the</strong>r study is required on A. pillansii <strong>and</strong> Pachypodium<br />

namaquanum (halfmens), both rare <strong>and</strong> threatened species.
