Description

Idea

With global temperature on the rise and drastic climate changes the frequency and intensity of heat waves are also increasing [1]. 

In 2022 Europe alone had 61500[2] deaths due to heat waves. In particular elderly (>65), children & people with chronic diseases are at greater risk. If this group of people live in a town or village far from health care infrastructure they face a multiplied risk during heat waves. A study has shown that the death rate due to heat waves has increased by 18% for vulnerable people living in rural areas[3]. 

Mitigation and adaptation strategies must be implemented to protect at-risk populations against heat waves. Our strategy to protect this population against heat waves is:

  1. Identify which areas and populations are at greater risk using data from Sentinel 3

  2. Build warning systems targeting the identified areas and populations. Warning systems can be implemented in several forms we target the following:

    1. App showing live heat wave risk index

    2. SMS subscription to at-risk population 

    3. Live roadsigns at roads entering the local towns and villages that provide real-time warnings for heat waves

  3. Provide this insight to government and local authorities so they best can plan where they should locate first aid responders, shelters, and new health infrastructure

The goal is to provide better protection and warning systems to at-risk populations against heat waves. The key stakeholders are local authorities, municipalities, and the government. The insight we provide into where the at-risk population is located is valuable information for authorities implementing disaster plans such as Rijkinstituut voor Volksgezondheid en Milieu (RIVM)  (National Institute for Public Health and Environment) in the Netherlands. The specific authority depends on country to country. 

EU Space Technologies

We name a map that will identify at-risk population as the Heat Stress Vulnerability Map. Different layers of data are used to create the Heat Stress Vulnerability Map and thus pinpoint the areas and at-risk populations.  

The Heat Stress Vulnerability map combines two key information: the accessibility of healthcare infrastructure together with the risk index of intense temperatures.

The Sea-Land-Surface-Temperature-Radiometer (SLSTR) instrument on board Sentinel 3 will be used to perform LST measurement.  By combining Sentinel 3 data together with Landsat 8 data we can increase the resolution of land surface temperature (LST) estimate [6] [7]. With historical data we can identify the areas that are more affected by the heat waves. In the future we also aim to identify the risk areas of heat islands within cities with higher resolution satellite data. 

The accessibility of healthcare infrastructure can be computed from the hospital location data released European Union data together with the route map information Following the steps of [4] and [5].

Space for International Development & Humanitarian Aid

In the context of the Hackathon, we tackle challenge #1 where we are focusing on the lack of infrastructure for remote areas during heat waves. We do site planning and selection for where to:

  1. Implement warning systems

  2. Locate first responders and aid shelters for disaster mitigation 

  3. Build new health care infrastructure (e.g. hospital) to reach the at-risk population
