Cities and flooding: Lessons in resilience from case studies of integrated urban flood risk management

摘要: Flooding can cause disruption and devastation in cities, with massive damage to livelihoods, property urban infrastructure as recently experienced New York City, Jakarta, Bangkok, Accra, Mississippi Queensland. For cities developing nations, unplanned expansion, poor services, inadequate drainage weak institutional capacity multiply the negative impact of flooding. In such circumstances, floods often affect informal settlements bring additional burden diverting resources away from poverty alleviation other development efforts. Preparing for future floods, which may become more frequent future, integrated flood risk management recognises that reduction relies solely on engineered defences be uneconomic, impractical or make worse under certain circumstances. Therefore authors advocate a holistic forward-looking approach improve resilience appropriate measures are combined non-structural mechanisms, land use planning, emergency preparedness recovery planning. Decision-makers this guidance implementing balanced robust solutions management. Funded by World Bank / Global Facility Disaster Reduction Recovery (GFDRR), flagship report ‘Cities Flooding: A Guide Integrated Urban Flood Risk Management 21st Century’ was designed provide operational assistance policy-makers technical specialists, particularly rapidly expanding towns world, how best manage floods. Comprehensively dealing available structural measures, handbook provides common guiding principles building Over 50 case studies, carefully selected extensive literature review, workshops consultations, illustrate current practice, challenges, lessons learnt around world. International local were held test disseminate key findings recommendations. major objective research project develop set policy practical recommendations, based inputs expert participants at workshops, support implementation through structured, iterative participatory process.
