The health of millions of people in the Zambezi basin is under threat due to an increase in the occurrence and spread of water-borne, vector-borne and respiratory diseases resulting from climate change related events (Boko and others 2007 in SARDC and HBS 2010). As a result of rising temperatures, it is predicted that the malaria-carrying female Anopheles mosquito will spread to parts of the region where it has not been found before by 2100 and there will be longer seasons of transmission in other areas (IPCC 2007 in SARDC and HBS 2010). New malaria areas include the southern highlands of Tanzania. In the Caprivi Strip in Namibia, malaria cases rose from 380 500 in 1993 to 444 000 in 2003 while in Zambia cases rose from just below 2 million in 1990 to 4.5 million in 2006 (SARDC and HBS 2010).
