  6. 6. © Western Cape Government 2012 | Longer Term Climate Outlook Western Cape Climate Change Response Strategy and Action Plan Climate change – shift in weather patterns; more frequent severe weather events; increased wind speeds Increases in temperature in many regions and resulting changes in precipitation patterns Estimated that by 2050, rainfall in the Western Cape is likely to have decreased by 30% More flooding events → less infiltration and recharge of ground water Quality of the water resource, as impacted on by human activities, becomes even more important More fires and droughts → poorer quality due to erosion 6

  13. 13. © Western Cape Government 2012 | Key messages • The current drought can only be broken with 3-4 years of good rain • The effects of the current drought are long term. • We are too dependent on rainfall and surface water sources – need to diversify • Businesses need to adapt to a ‘new normal’ • Focus on CCT & water supply augmentation at moment, but seeing much more severe problem in other municipalities e.g. Eden

Precision Irrigation Programme - pilot in NC barley irrigation - 48% (19.2-mill hectoliter) water saving yr 1 – being expanded 10x. Intensive alien vegetation clearing programme in 2 areas reducing water loss of between 13% - 20% pa in neighbouring dams • Coca-Cola Beverages SA - 726 million litres of water savings. 2010: 2.13 litres water / litre soft drink – 2016: 1.7 litres/ litre soft drink • Nestle’s Mossel Bay factory in South Africa cut its water usage by 54% in 2010. New equipment R1.2 million – rest through awareness campaign, measurement of water usage, action plan & continuous improvement and advertising of results

Saving 35% water on farms.

  20. 20. © Western Cape Government 2012 | We need all to play a role & to promote innovation
  21. 21. © Western Cape Government 2012 | Economic response needs to be twofold Maximise economic opportunities – new / expanded technologies & services Reduce economic risk of water shortages and increased costs
  22. 22. © Western Cape Government 2012 | Need to also build the supply side – the water sector Stimulate supply of technologie s & services Stimulate demand for technologi es & services Financing incentives & support for water sector Testing, demos & accreditation Communication of costs & benefits of efficiency, supply & reuse options for households & municipalities Financial incentives / access to finance for users (residents & businesses) Awareness raising for users Use of legislation e.g. by-laws, building standards Maximise economic opportunitie s – new / expanded technologies & services
  23. 23. © Western Cape Government 2012 | What can businesses do to reduce economic risks? | 23 Understand water uses and risks Water efficiency interventions Onsite re- use Alternative water supply • Water audits • Meter and Monitor • Water quality requirements (fit-for- purpose) • Set targets • Identify risks • Efficient processes and behavior • Efficient fittings & technologies • Water-wise landscaping • Greywater re-use • Process water re-use • Water exchange network • Treated effluent • Groundwate r • Rainwater/ Stormwater • Desalination Increasing cost and complexity Source: GreenCape Need to assess: • Ease of implementation and cost • Water saving / water augmentation potential • Fit for purpose solutions • Own operations vs supply chains
  24. 24. © Western Cape Government 2012 | Which sectors will we be focusing on? Highly & moderately intensive users: • Agriculture & agri- processing • Construction • Manufacturing Tourism Adds stress to municipal water systems in peaks (which affects municipal peak demand without commensurate revenues) & potentially significant reputational risk of water shortages Play a role in supporting change: • Retail • Insurance • Tourism • Property development • Tourists use 3-8 times more water that residents in developing countries* • 16 745 000 international tourist & 14 742 000 domestic tourist bed nights in WC = 27 393 Ml/ yr (@87 litres/p/d) = 75Ml / day (conservative) • 82 181Ml/yr (3x 87 litres/p/d) = 225Ml/day (3x) *Source: Becken, S (2014) “Water Resources and Industry”, Water Resources and Industry, Vo.l 7-8, pp. 9 – 22. • Collaborative programmes needed between businesses relying on similar supply chains • Sharing of experience
