Crowdsource module for climate hazard mapping

The Crowdsource module for climate hazard mapping visualises publicly generated climate data in a digital map. Finding ready-to-use spatial data on climate hazards and vulnerable locations can be a challenge. Local crowdsourcing presents an opportunity to collect this information through methods such as community mapping. This method is particularly useful for city representatives wishing to plan adaptation action in growing urban centres. Citizens or specific user groups are asked to map climate information via a questionnaire. The resulting dataset can be used to validate technical data or help to prioritise actions. Besides collecting data, the crowdsource module engages citizens and initiates discussion, helping to raise public awareness about climate adaptation.  

Benefits of using the tool

  • Identify areas vulnerable to a climate hazard of interest for the city e.g. heatwave, flooding.
  • Validate existing flood/heat maps.
  • Involve citizens, stakeholders and local organisations by giving them an active role. This can help increase support for a city’s (adaptation) policy.

City Hub experiences

The city of Cork is using the tool to enhance community climate action activities.  

Triple-A phases and complexity

The tool can be mostly used in the Analysis phase to find vulnerable areas in the city. In addition, the tool can be used in the Action phase to determine if you want to take certain actions at a specific location.

Overall level of complexity: Level 2 (customized approach)

The crowdsourcing module for Cork is currently being tested by Geography students of University College Cork. The example can be found here.
