“…Satellite observations identify populations in areas of known inundation risk and can inform appropriate adaptation efforts, including flood protection 5 and managed retreat 16 at local and regional levels 17 . For example, observed change in population in inundated areas aids local governance efforts to track vulnerability over time and plan flood resilient futures 54 . Flood observation data may inform market signals to price municipal bonds 55 , insurance 15 , and other financial instruments to plan for a changing (or already changed) tax base.…”

Flooding affects more people than any other environmental hazard and hinders sustainable development1–3. Investing in flood adaptation can reduce loss of life and livelihoods 4,5. However, where and how floods occur, and who is exposed, is changing due to rapid urbanization 6, new flood mitigation infrastructure 7,8, and increasing human settlements in floodplains9. Previous studies estimating population exposed to floods are limited by lack of observational data, relying instead on global models with high uncertainty4,10–14. Here we use nearly two decades of daily satellite imagery at 250 meter resolution (MODIS) to develop new estimates of flood extent and population exposure for 913 large flood events from 2000-2018, estimating 2.23 million km2 of flooded area and 290 million people directly affected. We find the at least 86 million people newly settled in a location where satellites observed inundation in the past 20 years. This represents a 20% increase in the proportion of population exposed to floods, ten times higher than previous estimates10. Near-future climate change projections (2030), indicate the proportion of population exposed to floods will continue to expand. Our findings can aid prioritization of global flood adaptation investment and inform adaptation strategies, from insurance to managed retreat, at local scales15–17. As satellite coverage and resolution increase, we anticipate observation of flood events to aid understanding where floods change and how to adapt. This flood event database will contribute to improved accuracy of global and local flood models, vulnerability assessments, efficacy of adaptation intervention, and understanding interactions of land change, climate, and floods.

“…Issues have included methods for climate risk assessments, climate adaptation mainstreaming, and public‐private collaboration (e.g. Glaas et al, 2018; Storbjörk et al, 2019; Opach et al, 2020; Hjerpe et al, 2020; Malmquist et al, 2021). During the collaborative process, the researchers have participated in regular meetings with a cross‐sectoral adaptation working group, conducted numerous interviews with municipal officials, elected politicians, and citizens, conducted questionnaire studies, and participated in dialogue meetings between the municipality, companies, and citizen groups.…”

Disentangling municipal capacities for citizen participation in transformative climate adaptation

Transformative adaptation is described as decisive to mitigating risks and to seizing opportunities from a changing climate, requiring new ways of governing, planning and collaborating, alongside technical innovations. Building municipal capacities for citizen participation in adaptation is important to enabling such transformational changes but remains challenging. By applying capacities distilled from the literature on Urban Transformative Capacity and Participatory Climate Governance in a Swedish municipal case, this study aims to disentangle key limits for, and innovations to strengthen, local capacities for citizen participation in transformative climate adaptation. Interviews with municipal officials, focus groups with citizens, and document analyses were employed to analyse how climate adaptation and citizen participation are governed, and how these policy areas are interacting and could be bridged. The study points at conditions that foremost prevent bridging established policies and practices on adaptation and citizen participation, stemming from the different logics and distribution of responsibility within, and lacking collaboration between, these separated policy areas. The analysis concludes that potential ways to enable citizen participation in adaptation involve: broadening the geographical boundaries of deliberations; redefining the target groups for participation; co‐designing participation targets, approaches and evaluation; and developing new ways to analyse and act on the patterns in the citizen inputs received.

High temperatures and heatwaves are becoming more frequent, but heat vulnerability is rarely considered within local authority city design and statutory land-use planning processes. Here, we describe an approach to assess heat vulnerability in Birmingham, the second largest city in the UK. The approach uses open access data and GIS techniques that are available for built environment practitioners. Heat vulnerability is assessed by combining four datasets: surface temperatures, Local Climate Zones, green space, and Indices of Multiple Deprivation. The assessment shows that central and eastern areas of Birmingham that have the most compact urban form, least green space, and highest levels of deprivation are most vulnerable to heat. We evaluated the approach against previous climate research, examined the approach and datasets at the local scale, and described how heat vulnerability can be (and is being) incorporated into decision making. This project combines three key innovations: (1) the decision-centric process that focuses the method on the decision that needs to be made, minimizing inertia related to scientific or modeling uncertainty and reducing resource-intensity; (2) the co-creation process with Birmingham City Council, who have statutory powers for planning within the city, thereby ensuring that heat vulnerability is embedded within decisions on the suitability, design, and location of sites for future development; and (3) the open access and technically appropriate methodology which can be applied to any urban area in the UK, using the open access datasets described here, or globally, using locally applicable data sources.
