Analysis of climate change impacts has typically targeted rural areas in Asia to date, and when attention has focused on the urban environment it has been primarily in the context of the larger mega-cities. However, issues affecting rapidly urbanising secondary cities in Asia (which face a specific set of challenges vis-à-vis climate change, in combination with development dynamics) are less well researched and understood. Capacity to respond is also arguably lower in these regional cities, as evidenced by a lesser concentration of investment, resources, institutions and skills. In response to this knowledge deficit, this project set out to develop a participatory toolkit that would enable local communities to assess the climate risks facing their cities in south-western Bangladesh (Satkhira) and central Vietnam (Huế). The toolkit, comprising a portfolio of participatory assessment approaches, was tested in the respective local communities to ensure it was fit for purpose; with the intention of providing a platform for informing context-specific adaptation options.
