Impacts Of Droughts In South Africa

Drought impacts, however, are not the result only of insufficient rainfall or searing temperature. In most cases, drought impacts are the outcome of the interaction of a number of social and other human factors that can heighten the vulnerability of communities and various exposure units (e.g., vegetation) and reduce resilience of society and ecosystems to the natural hazard (Dilley, 2000 Vogel et al, 2000). As a result of these components of drought, a number of impacts are recorded. The scale...

Causes Of Droughts In South Africa

Having described the pattern of rainfall-producing systems in the country, attention now focuses on some of the causes of periods of insufficient rainfall and droughts. The forcing mechanisms for droughts are well documented for the southern African region (see, e.g., Tyson, 1986 Mason and Jury, 1997 Lindesay, 1998 Tyson and Preston-Whyte, 2000). Much of the recent research in the country has focused on the prolonged droughts of the last two decades (namely the 1980s and 1990s) Tyson and Dyer,...
