Water Resilient Cities: Climate Uncertainty & Urban Vulnerability to Hydrohazards

Project Details


Cities are the driver of regional, national and indeed global economies. The complex inter-relationship between urban areas and their hinterlands is a vital aspect of a city's economic success. Hinterlands supply resources such as water, food and energy; while being economically-tied to the urban area through trade. Creating resilient, sustainable, water-secure cities depends on our understanding of the potential future risks of changing hydro-hazards (floods and droughts) and our ability to increase our resilience to them. Worldwide, in 2014, hydro-hazards resulted in over $16Bn (floods) and $7.5Bn (droughts) in damages. While, in the UK over the past five years there have been significant challenges to water management posed by hydro hazards. Since 2000, flooding has caused over £5Bn worth of damage, of which £3Bn was caused by the 2007 floods, and over £1Bn from the 2013/14 winter storms, impacting households and businesses alike. Similarly direct costs (estimated at £70-165M) from the recent UK drought (2011-12) arose from impacts to urban water supplies, and industry. Projections of future climate recognise that there is an added uncertainty in temperature and precipitation trends which may exacerbate the frequency and severity of such hazards.
