2/16

Flooding is a serious and growing

development challenge.The occurrence of floods is the most frequent among all natural disasters globally.

Flood events, 1970-2011


3/16

Urban agglomerations with more than 750,000 inhabitants, 2010

Climate change is perceived to have a significant impact on flood risk, whileurbanization is compounds flood risk, and urban areas have been hit particularly

hard by flooding.

Increasing risk & impact

Water Resources Strategy

Water Resources Management

and Development is essential

for growth & poverty reduction.

Assist with stock of wellfunctioning infrastructure.

New business model for high

risk, high rewardengagement.

Tailor to country conditions,consistent with the Country

Assistance Strategy (CAS).

East Asia & Pacific:major water resources programs.... major challenges!

Policy work:

Water Resources Assistance Strategies: Regional Strategy 2003, China 2002, Philippines2003, Mekong Basin 2005.

Challenge:

Balancing rapid development with: megacities, declining water quantity & quality,

environmental degradation, major flood & drought risks.

Very large operational agenda, with primary focus:

Halt groundwater & surface water overexploitation (China).

Reduce pollution (China, Philippines, Indonesia, Vietnam).

Safeguard environmental flows (China, Philippines, Indonesia, Mekong).

Improve flood mgmt. (China, Philippines, Vietnam, Indonesia, Cambodia).

Stabilize watersheds (China, Philippines, Indonesia).

Address transboundary issues (Mekong region).

Improve water supply and sanitation (WSS) and irrigation and development (I&D)(China, Philippines, Indonesia, Vietnam, Cambodia AND Laos (Nam Theun II -hydropower, poverty alleviation, infrastructure investments).


9/16

Urban flooding is becoming more dangerous and more costly to manage.

Repeating past mistakes can have disastrous consequences for the presentand the future.

Policy makers require a clear vision of the alternatives and the methods and

tools to assist them in making the right choices.

A concerted effort needs to be made today to promoteIntegrated Flood Risk Management!

Multi-disciplinaryandmulti-sectoralapproach.

Comprehensive, locally specific, integrated, and balanced measuresacross all involved sectors.

Robust solutions can contribute to flood risk reduction, at the same

time creating opportunities to promote better and more sustainable

urban development.

Policy Implications


10/16

A forward-looking approach:

Integrated Urban Flood Risk Management

o Operational guidance on how to manage the risk of

floods in a quickly transforming urban environment

and changeable climate.

o Over fifty case studies, a series of how-to sections

and a set of guiding policy principles, illustrate the

state-of-the-art approach to integrated urban floodrisk management.

o Comprehensive and user-friendly, this guide serves

as a primer for decision and policy makers, technical

specialists, central, regional and local government

officials, and concerned stakeholders in the

community sector, civil society and non-

governmental organizations, and the private sector.

Reduction and Recovery


11/16

Guiding Principles

1. Every flood risk scenario is different: there is no flood management blueprint.

2. Designs for flood management must be able to cope with a changing and uncertain future.

3. Rapid urbanization requires the integration of flood risk management into regular urban

planning and governance.

4. An integrated strategy requires the use of both structural and non-structural measures and

good metrics for getting the balance right.

5. Heavily engineered structural measures can transfer risk upstream and downstream.

6. It is impossible to eliminate entirely the risk from flooding.

7. Many flood management measures have multiple beneficial side-effects.

8. It is important to consider the wider social and ecological consequences of flood

management spending.

9. Clarity of responsibility for constructing and running flood risk programs is critical.

10. Implementing flood risk management measures requires multi-stakeholder cooperation.

11. Continuous communication to raise awareness and reinforce preparedness is necessary.

12. Plan to recover quickly after flooding and use the recovery to build capacity.


12/16

The implementation of both structural and non-structural measures will

require wider participation and a change in traditional management

methods to be successful:

o

Measures need to be linked to existing urban planning andmanagement policies and practices.

o Greater coordination between city governments, national

governments, ministries, public sector companies, civil society, non-

government organizations, educational institutions, research centers,

and the private sector.

Prepare for the Unexpected!


13/16

Asset Management(building is easy maintaining is not)

The systematic and structured combination of management,

financial, economic and engineering practices to plan for the

creation or acquisition, maintenance, operation, replacement

and disposal of physical assets necessary to provide an agreed

level of service in the most cost effective and sustainable

manner.

Water Resources and Flood Control

Management Recommendations

Immediately rehabilitate and increase the drainage capacity ofinfrastructure and pumping stations.

Reduce the maintenance gap of the vital hydraulic infrastructure

assets. Accelerate the implementation of the Royal Initiative for Flood

Controls and Management considering social impacts and landuse compensation.

Strengthen the 162 km Kings Dyke to 1/50 to 1/100 yr floods(est. 21 to 42 billion THB) and strengthen the ring dykes aroundthe industrial parks.

Update JICAs Integrated Plan for Flood Mitigation in the ChaoPraya River Basin (1999).


16/16

Overarching Infrastructure Recommendations

Appoint a champion for water management, at high level, tobring together all actors in the sector.

Move the existing water basin authority to central position

under the champion.

Develop a comprehensive hydraulic model for the Chao PhrayaRiver Basin, incorporating climate change impacts.

Complete a hazard mapping program for all areas within the

Basin, focusing on floods.

For roads, identify networks of strategic links that must be keptopen at all times, and prepare them to achieve this.

Comprehensive waste and sewage management and

modernization plan.
