Issues 5
#00250Homes ignite from wildfire embers, flames and neighboring structures
Combustible roofs, vents, attachments and immediate surroundings let wind-driven embers and nearby burning structures ignite homes even beyond the main flame front.
#00249Development continues in high-risk wildland-urban interfaces
New homes and facilities are built where evacuation, structure defense and reliable infrastructure may be impossible under plausible wildfire conditions.
#00243Homogeneous plantations create continuous wildfire fuel structures
Large areas with similar species, age, spacing, and residues can transmit fire efficiently, exposing neighboring settlements or ecosystems to concentrated risk.
#00235Wildfire smoke creates an under-managed public health burden
Wildfire smoke exposes populations far beyond the burn perimeter to harmful fine particles, disrupting health, work and daily life across regions and borders.
#00231Settlements are increasingly exposed to wildfire
Development in fire-prone landscapes, combustible buildings, and fragile utilities expose communities to ember storms, structure-to-structure spread, and infrastructure failure.
Solutions 5
#00337Share wildfire cause, fuel, exposure and outcome data
Publish interoperable, privacy-respecting data across agencies so prevention and response decisions can be evaluated against actual causes and harms.
#00292Disclose wildfire risk in property transactions
Give buyers and renters clear parcel and community wildfire information, including evacuation, insurance and mitigation obligations, before commitment.
#00265Use targeted access restrictions and multilingual fire warnings
Restrict access or specific activities at high-risk sites and communicate current rules in languages and formats understood by residents and visitors.
#00263Use covered conductors, fault detection and selective power shutoffs
Reduce utility ignitions with insulated or covered equipment, fast fault isolation and narrowly targeted de-energization during exceptional fire weather.
#00256Use future climate scenarios in wildfire planning
Plan land management, staffing, infrastructure and evacuation against plausible future fire weather instead of relying only on historical seasons and maps.
