Analysis of Droughts in the Central Region of South Africa

How droughts will affect South Africa's broader economy. Recent research by WWF South Africa and the Council for Scientific and Industrial Research (CSIR), with funding from Sanlam, mapped out South Africa’s strategic famine, between floods and droughts. InTROdUCTIOn An Introduction to South Africa’s Water Source Areaspage 10 An Introduction to South Africa’s Water Source Areas page, The objective of this study was to characterise meteorological droughts in the Central Region of South Africa using Standardised Precipitation Evapotranspiration Index (SPEI) and to examine if there is a relationship between drought and El Niño events. The SPEI was used to quantify the precipitation deficit over time and space across the catchment for the time-scales that are important for.

We identify major ocean currents around Africa and their influence on climate control. We look at the processes of El Nino and La Nina. Lesson 4: Drought and Desertification In this lesson on Drought and Desertification we assess which areas are prone to drought and desertification. We look at causes of droughts and links to El Nino. 8/31/2012 · Drought is a major disaster in South Africa in terms of total economic loss and number of people affected.
