Answer:
When discussing drought, one must have an understanding of aridity and the difference between the two. Aridity is defined, in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture" (Glossary of Meteorology, American Meteorological Society). Drought is "a period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance". Aridity is measured by comparing long-term average water supply (precipitation) to long-term average water demand (evapotranspiration). If demand is greater than supply, on average, then the climate is arid. Drought refers to the moisture balance that happens on a month-to-month (or more frequent) basis. If the water supply is less than water demand for a given month, then that month is abnormally dry; if there is a serious hydrological impact, then a drought is occurring that month. Aridity is permanent, while drought is temporary.
South Africa's location makes it a key spot for renewable energy in the forms of wind, hydroelectric and solar, as it is on the peninsula of the continent it has access to many of these rich resources. There is also a great deal of industry in South Africa, particularly in the mining of metals, as one of the country's largest exports. This extraction uses huge amounts of energy in the process and most of this equipment used in the extraction pumps toxic gases and chemicals into the atmosphere, if SA uses more renewable energy sources, the levels of pollution will decrease.
