Climate change and planned urban expansion in floodways will compound flood risk for the City of Hue, according to a new climate vulnerability assessment implemented by the Thua Thien Hue Province Climate Change Working Group and ISET-Vietnam under the M-BRACE program. The assessment highlights the importance of planning future urban development on the basis of solid assessments of future climate risks. When the B2 scenario is applied there are clear risks of reduced rainfall in the dry season, and also 30% more rainfall in the flood season. As worrying as these findings are, the assessment points out that historical precipitation records demonstrate that Hue has moved beyond the B2 scenario, and that these are underestimates of the full level of water-related climate threats. There are also concerns that existing infrastructure—drainage in urban areas, and upstream flood protection—are not able to cope with current rainfall pressures let alone future climate threats.
