The World Bank has retained Chreod to design a methodology for calculating present and future risks to cities from natural hazards, including those arising from climate change. The methodology will include: assessment of metropolitan elements at risk; calculation of hazard probabilities; exposure analysis; vulnerability analysis; and individual risk calculation and aggregation. The model will be tested extensively in Bangkok (Thailand), Ningbo (China), and Manila (Philippines) prior to its application in a larger number of cities around the world.
