Wildfires WHO Response

The magnitude of the physical and human costs from wildfires can be reduced if adequate emergency prevention, preparedness, response and recovery measures are implemented in a sustainable and timely manner. 

WHO works with Member States to build resilient and proactive health systems that can anticipate the needs and challenges during emergencies so that they are more likely to reduce risks and respond effectively when needed. 

As the health cluster lead for global emergencies, WHO works with partners to in preparing, preventing, detecting, responding, and recovering from emergencies and disasters, including environmental. These activities include:

  • putting in place early warning systems and issuing health and air quality advisories;
  • developing national policies, recommendations and national emergency response plans;
  • strengthening human resources for disaster management;
  • containing the release of hazardous materials;
  • assessing health needs of the community and infrastructure damage;
  • restoring primary care services, like immunization, child and maternal health, and mental health;
  • establishing and managing stocks of relief supplies and equipment
  • collecting, analyzing and disseminating information related to emergencies and disasters that are likely to occur in the region:
  • calling for emergency funding to support health action.

Wildfires

A wildfire is an unplanned fire that burns in a natural area such as a forest, grassland, or prairie. Wildfires are often caused by human activity or a natural phenomenon such as lightning, and they can happen at any time or anywhere. In 50% of wildfires recorded, it is not known how they started.

The risk of wildfires increases in extremely dry conditions, such as drought, and during high winds. Wildfires can disrupt transportation, communications, power and gas services, and water supply. They also lead to a deterioration of the air quality, and loss of property, crops, resources, animals and people.

Wildfires and volcanic activities affected 6.2 million people between 1998-2017 with 2400 attributable deaths worldwide from suffocation, injuries, and burns, but the size and frequency of wildfires are growing due to climate change. Hotter and drier conditions are drying out ecosystems and increasing the risk of wildfires. Wildfires also simultaneously impact weather and the climate by releasing large quantities of carbon dioxide, carbon monoxide and fine particulate matter into the atmosphere. Resulting air pollution can cause a range of health issues, including respiratory and cardiovascular problems. Another significant health effect of wildfires is on mental health and psychosocial well-being.
