Abstract: The dune thing Desert dunes cover some 5% of Earth's land surface, including almost 30% of Africa, where vegetated dunes are widely used in agriculture, but the potential impact of global warming on dune systems is not well understood. New climate modelling studies suggest that for a range of CO2 emissions scenarios, extensive dune systems from South Africa to Angola will be activated as a consequence of future global warming by 2010. This shift in desert dunes could have drastic effects on the environment, and marked socio-political implications for the countries in which the dune systems fall.
