Wildfires: Managing the risk


How can we limit the spread of wildfires and save people and property?

Wildfires are already a serious problem, and climate change will only make the problem worse, as I’ve discussed in my two prior posts. Reducing carbon emissions can help keep the problem from growing, but we need to deal with the risks we’re already facing. That is going to require a portfolio of risk management strategies. We need to ramp up all of them.
Land Use Controls.

There are increasing numbers of people moving into the wild-land urban interface (WUI).The USDA’s report on the WUI says that 3.8 million people live in that zone in California alone. Nationally, a million homes were added to the WUI just in the decade from 1990-2000. That simply isn’t sustainable.

Human activities increase the risk of fire from sparks or burns, and homes are typically highly flammable and help fires spread more quickly. Better land use controls could limit development in high risk areas. Easier said than done, however, given development pressures. According to a 2013 study, ” land use planning for wildfire has yet to gain traction in practice, particularly in the United States. However, fire history has been used to help define land zoning for fire planning in Italy, and bushfire hazard maps are integrated into planning policy in Victoria, Australia.” By 2016, however, Headwaters Economics was reporting on five Western US cities that were taking advantage of at least some land use tools to reduce fire risks, though none seem to have imposed outright bans on development in high-risk areas.

Buyouts may be a fallback in extreme situations. Building codes can also help — for instance, by requiring fire-resistant roofs on new houses. Liability rules for fires have to be carefully considered. Making utilities liable for fires can cause them to take greater precautions, but the prospect of compensation could also encourage people to live in unsafe areas. On the other hand, fire insurance costs can send an important price signal about the risks of WUI property ownership, as some Californians are already beginning to experience.
