Description: <DIV STYLE="text-align:Left;"><DIV><P><SPAN>The 2018 national and transboundary surface-water SWSAs (refer to the map that follows) cover about 124 075 km2 (10% of the region) and provide a MAR of 24 954 million m3 (50% of the total). The greatest volume of MAR is generated by the Southern Drakensberg (9% of national and transboundary MAR), followed by the Eastern Cape, Northern Drakensberg and Maloti Drakensberg, and the Boland. The Boland has the highest MAR per unit area (3588 m3/ha/year), followed by Table Mountain, the Northern Drakensberg and the Mpumalanga Drakensberg.</SPAN></P><P><SPAN>Seven of these SWSAs are transboundary areas because Lesotho and Swaziland include portions of important SWSAs for South Africa. The portions of the SWSAs that fall within Lesotho (Eastern Cape, and the Southern, Northern and Maloti Drakensberg) cover 18 570 km2 and generate a MAR of about 3522 million m3. This MAR sustains the Orange and Caledon Rivers and supplies water to Gauteng via the Lesotho Highlands water supply system. In the case of Swaziland, the portions of the SWSAs falling in this country (Ekangala Drakensberg, Mbabane Hills, Upper Usutu) total 9376 km2 and produce a MAR of about 2053 million m3. In total, the SWSAs in these two countries produce about 11% of the total MAR, which is a substantial contribution that needs to be protected.</SPAN></P><P><SPAN>SWSAs for surface water and groundwater in South Africa, Lesotho and Swaziland. SWSAs for groundwater were not identified in Lesotho and Swaziland because no suitable data were available</SPAN></P></DIV></DIV>
