The Integrated Vaal River System (IVRS) is a strategic national asset providing water for a range of urban, mining, agricultural and industrial uses. The IVRS supports 45% of South Africa’s population and 60% of the national economy, including the Gauteng Province. On June 18th, the National Business Initiative (NBI) will coordinate a roundtable on behalf of its private sector members, with co-convening support from the Global Compact Network South Africa and the UN Global Compact’s CEO Water Mandate. The discussion will be limited to key companies and water users in the Vaal system. The roundtable will focus on a brief overview of the current state of the IVRS; ongoing and current initiatives within the IVRS; the CEO Water Mandate, Global Compact Network South Africa, and NBI pilot testing of ‘contextual water targets’ in the upper Vaal, including the implications for the Vaal system; and work required in the future, including opportunities for collaboration. The Pacific Institute is co-secretariat of the CEO Water Mandate, a UN Global Compact initiative that mobilizes business leaders on water, sanitation, and the Sustainable Development Goals. Endorsers of the CEO Water Mandate commit to continuous progress against six core elements of stewardship and in so doing understand and manage their own water risks. The roundtable will take place on Tuesday, June 18th 2019 at the NBI’s offices in Sandton, South Africa, from 14:00 to 17:00 SAST.
