Bridging the Investment Gap in flood risk management

1. Bridging the Investment Gapin flood risk management Chris Zevenbergen Chair FloodResilience Group IHE Delft & GCECA ICFM7

2. 2 key questions What drives investors? Can we make a difference as water professionals?

3. Finance & FRM: where are we ? Investments in water security are conditional to drive sustainable growth (GWP-OECD, 2016) Investment needs for FRM are large and growing Capacity to absorb finance is limited: investment planning, programming and implementation gap (OECD, 2017) This leads to (unacceptable)low levels of investments both in developed as well as in developing countries (OECD, 2015; WB, 2015; ASCE, 2017)

4. What are the consequences? Increasing exposure due to autonomous growth (emerging countries) Ageing systems (advanced countries) Maladaptation (both) Escalating (urban) flood damages

5. Changing landscape of FRM • Globalization, urbanization, decentralization • Cities – regions as fundamental spatial units for global economy • Devolution of power to local government • Innovation in information systems (e.g. citizens observatories) • Finance is no longer a limiting factor

6. Barriers for investments in FRM (modified after: HLPW, 2016) High sunk costs & long pay-back period Land acquisition: lengthy processes & lack transparency Diverse beneficiaries, benefits not easy to be monetized Uncertainty in assessing (hydrological) risks Emerging approaches as GI* lack performance track record Flood infrastructure: category of high risk asset classes *green infrastructure

7. Actions to overcome barriers (OECD-WWC Roundtable, 2017) Maximize the value of existing assets Select investment pathways that reduce water risks at least cost over time (demonstrably sustainable!) Ensure synergies and complementarities with investments in other sectors (economies of scale, win-win) Scale-up financing through attractive risk-return allocation

8. Select investment pathways InfrastructureInvestmentProjectCycle UP-STREAM (plans) DOWN-STREAM (projects) Strategy Development & Programming National Development Plan/Strategy Regional/City Development Plan/Strategy Projectstructuring Feasibility Study Key features interface: Understand andassessflood risk Valuation of alternative scenario’s Long-term, adaptivedevelopmentstrategy Package of projects FinancingArrangements Learning ProjectImplementation Operation& Maintenance (Modifiedfrom CDIA, 2015)

10. China Leading in renewable energy investments (mitigation) Falls short in investing in flood management infrastructure (adaptation) Globally highest investment needs (30% of total needs, Global Infrastructure Hub, 2017) Private funding is needed to bridge the gap

12. Urban population increased a six fold in number since 1980 (for comparison, a similar relative increase took Europe more than 120 years) An average annual growth rate of 12% over the past 15 years!

13. China’s (urban) challenges Flooding Among the current 654 cities in China, 641 of them are exposed to frequent flooding Economic loss caused by urban flooding in China in 2013

14. Sponge Cities program (launched 2013) • Sponge Cities program: "building Sponge Cities where stormwater can be naturally conserved, infiltrated, and purified“ (President Xi Jinping, 2013 ) • Costs ≈ $1.5 trillion (657 cities, 20 years) • Challenge 30 pilot cities: • time for reflection and peer learning • private investments (lack of business model)

16. Bangladesh • 90% flood prone, 90% river basins located outside the country • Since 1950: 16 catastrophic floods • Typical example of an emerging economy (GDP= 6%) • National Delta Plan to be accepted in December 2017 • Frontrunner in the development of a comprehensive investment plan using ADM

17. Investment Plan(for the DP Bangladesh 2100) 80 projects (65 physicalprojects) selectedandprioritized Total capital investment: $ 38 bln Alltobestarted 1st 8 years Alignment 5 years planning cycle Major challenge: todevelopment the capacityneededtoimplement (incl monitoring andlearning) the plan

18. Egypt: Alexandria

19. Egypt: Alexandria flood November 2015 Worst flood ever in Alexandria (7 people killed, $250 mln damage) Extreme rainfall events will likely happen more frequently in the future Probability of occurrence of this type of storm events hard to predict The associated risks cannot be properly managed using ‘preventive’ approaches only

20. Scoping Mission report Implement Mitigation Action Plan: • quick-wins: invest in preparedness (emergency response & anticipatory water management) • develop long-term (transformation) strategy: requiring large investments (adapting existing infrastructure and new build) Development strategy will take time (> 5 yrs)

21. A Mitigation Action Plan for Alexandria

22. Conclusions (1) • FRM: high complexity, risky investments • Calls for a broad, integrated appreciation • Shifts needed: • focus on unlocking economic potential rather than on efficiency • from single projects to packages of projects (programs) • from short-term to long-term • from a robust to an adaptive approach

23. Conclusions (2) • FRM professionals need to: • have an understanding of the services FRM provides to people and businesses, and their interrelationship • acknowledge interests of various policy areas, levels of government & private stakeholders (incl. financing world) • provideevidence-based (long-term) investment scenario’s towardssustainabledevelopment • Collectivelearningwillbeessentialfordevelopmentandimplemenation
