FIGURE 12.10 Regional-scale periodicity—West 8, Happy Islands: Belgium, Dutch, and Flemish Coast, 2006; Magnus Larsson, Dune: Transcontinental Africa, 2008. Along with rural-urban dynamics, climate change–induced sea-level rise and desertification are also examples of periodic phenomena. These two strategies represent attempts to address sea-level rise and desertification as polar effects of climate change to retain currently inhabited regions. An alternate, lowest-risk version of this initiative would be to establish “safe zones” on the basis of those areas of the world least affected by climate change.
