New approaches to geoconservation in desert environments

Abstract

Deserts are areas of great landform diversity and distinctiveness. In the past there was a shortage of desert World Heritage nominations. This situation persists, though shows some improvement. However, there are also desert landform complexes associated with mixed World Heritage sites and sites on various national World Heritage tentative lists. There are also two desert UNESCO Global Geoparks, both of which are in China. In recent years there has been the development of geotourism in arid regions and this has led to a greater interest in the economic value of geoconservation. However, there are various landscape threats that need consideration and management, including off-road driving, military activity, urbanization, river diversions, quarrying and mining, development associated with energy industries, and anthropogenic climate changes. In this paper, the concentration is on warm desert landscapes, and on conservation of geomorphological features, rather than, for instance, sites of particular stratigraphic or paleontological value.
