Mapping out the health impacts of climate change

A new resource that maps climate change-related health vulnerabilities in our communities aims to enhance collaboration among Vancouver Coastal Health (VCH), Fraser Health and municipalities.

The climate vulnerability index — developed by a team of University of British Columbia (UBC) faculty of medicine researchers — measures how susceptible communities in the VCH and Fraser Health regions are to the health effects of extreme heat, wildfire smoke, flooding and air pollution.

“We know that climate change is affecting the health of British Columbians, and will continue to pose challenges in the future,” said Adrian Dix, Minister of Health. “The work of the UBC’s faculty of medicine researchers’ team, VCH, and Fraser Health will help communities and governments better understand and respond to the climate change-related health risks at a local level. I thank everyone involved for their on-going commitment to improving the health outcomes of the people in this province.”

Climate change is already impacting the lives of British Columbians and the frequency and severity of climate-related hazards are expected to climb in the coming decades. These hazards are associated with premature death, infectious disease, heart and lung disease, and cancer. These risks disproportionately affect certain populations, including children, seniors, and people with low incomes.

“Climate change is one of the biggest challenges facing our communities,” said Dr. Michael Schwandt, VCH Medical Health Officer. “We can use the information from the index to work with municipalities to build up their capacity to respond. For example, we can see which communities may be affected more by heat, and work with municipalities to develop response plans in those communities, such as opening cooling stations for people during a heat wave.”

VCH and Fraser Health are sharing the index with municipalities, regional districts, First Nations, community organizations and other partners to work together to build more resilient communities. The project’s findings are available to the public and can be viewed through an interactive, user-friendly website that walks visitors through each of the climate-related risks for their communities.

“The maps highlight how climate hazards affect everyone, but disproportionately impact those affected by social determinants of health, like low income or racism,” said Dr. Alex Choi, Fraser Health Medical Health Officer. “As we work together to respond, it will be vital to prioritize the populations who are more likely to experience climate-related health risks so that we don’t worsen inequities.”

Data from each community was used to calculate scores for exposure, sensitivity and adaptive capacity, which were then summarized to form an overall vulnerability score. The UBC research team collected more than 35 indicators and reviewed more than 280 epidemiological papers to create the vulnerability maps. Over time, the maps will be updated to reflect community preparedness, and changing demographics.

“Mapping vulnerability to the climate hazards that are relevant for our region can help target public health resources to the people and places most likely to be impacted,” said the project’s lead researcher Michael Brauer, a professor in UBC’s School of Population and Public Health.
