  1. Integrated Flood Management : the way to Harmonious coexistence with floods Avinash C Tyagi World Meteorological Organisation Geneve, Switzerland A contribution to Question 53 International Commission on Irrigation and Drainage 19th Congress, 15-18 September 2005, Beijing

  2. Floods as increasing Disasters

  3. Shortcomings of past FM Practise • Ad-hoc and stand alone • Reactive rather than proactive • Emphasis on structural measures • Monodisciplinary • Lessons from past failure

  4. why a new approach? Increasing Flood Risks • Population increase: Exposure • Economic Development: Vulnerability • Climate Variability: Hazard Frequency • Upstream Urbanisation: Hazard Magnitude Absolute safety against floods is a myth Climate change uncertainity Growing environmental concerns IWRM approach

  5. FLOOD RISK Exposure Flood magnitude and frequency RISK Vulnerability

  7. Rainwater infiltrates into the ground Runoff increases

  8. Integrated Flood Management: Objectives • Sustainable development: balancing development needs and flood risks • Maximising benefits: ensure livelihood security and poverty alleviation thereby reducing vulnerability • Minimising loss of life • Environmental preservation

  9. IFM: PRINCIPLES Risk Management • Mitigation and Preparedness • Response • Recovery and rehabilitation

  10. IFM: PRINCIPLES Water Cycle as a whole • Flood and drought management • Effective use of flood waters • Ground water and surface water interaction in flood plains

  11. IFM: PRINCIPLES Multi-hazard approach • Cross-sectoral integration of disaster management strategies • Disaster risk assessment • Early warning and forecasts

  12. IFM: PRINCIPLES River Basin approach

  13. IFM: PRINCIPLES Public Participation • Stakeholders participation in decision making • Coordination between institutions • Building resilience in the community • Addressing Gender based requirements • Exchange of data and information

  14. IFM: PRINCIPLES Public Participation Flood Information System consisting of • monitoring base: indicators; information systems; early warning threshold • knowledge base: technical data; social and economic data; land and water uses; risk knowledge • relational base: who’s who; contacts and coordinates; allocation of duties; • dialogue base: data exchange protocols; notification protocols; communication channels; rules and language; • conflict-resolution base: negotiation processes (location, timing, authority chosen for trade-off; compensation options, etc.)

  15. IFM: Towards a holistic flood management • Integration of • Land and Water Management • Upstream and Downstream • Structural and Non-structural • Short term and Long-term • Local and basin level measures • Top down and Bottom up decision making • Development needs and economic concerns

  16. Requirements of IFM Clear and objective policies with a multidisciplinary approach supported with appropriate • Legislation and regulations; • Institutional structures with appropriate linkages; • Economic instruments; • Enabling participatory processes; and • Information management and exchange mechanisms.

  17. Associated Programme for Flood Management • Establish the principles of IFM • Help assimilate principles of IFM within IWRM; • Identify gaps in present flood management practices and IFM • Support actions at local, national, regional or river basin level • Provide a platform for a common strategic vision, • Promote the implementation of effective policies and strategies; • Provide advice and relevant information on flood management issues; • Develop capacities in the countries to integrate flood management into sustainable development processes; and
