Guide for increased preparedness for heat waves – a tool for vulnerability charting

Research has shown that even today people are dying during hot periods and that still more may die in the future as heatwaves become more common and more extreme. Those who are most susceptible to heat are the elderly, people who take certain medicines or have certain illnesses and those who live on the highest and lowest floors of multi-family apartment blocks. By increasing emergency response capacity for heatwaves in the municipalities, it is possible to prevent susceptible residents from dying or becoming seriously ill.

The tool is aimed at municipal administrators in health and social care, as well as officials responsible for safety and politicians concerned. The tool is also suitable for use by environmental departments. If the municipality has established an administration-wide climate adaptation unit, that unit may find the tool useful as a way of preparing for periods of more extreme heat.

Once finalized, an analysis and list of remedies may answer questions such as:
• How many people who are especially susceptible to heat live in the municipality and how many of them are users?
• Where in the municipality (i.e. in which districts) do these people live?
• Does the municipality have any locations that can be used temporarily by those suffering from the heat to cool off?
• How can instructions, for use before, during and after a heatwave, be formulated for health and social care personnel?
• How can the municipality get information to heat-susceptible individuals ahead of a heatwave and how should the information be worded?

Examples of results include: maps showing the whereabouts of heat-susceptible individuals, geographical analysis of how outreach activities can be planned and evaluated, checklists for municipal personnel for use in outreach activities and information sheets for distribution to the public via the Web or otherwise.

The tool was developed by Botkyrka Municipality in association with Climatools.
