Academics call on world policy makers to rethink their wildfire policies for the good of the environment and human life.

Governments across the world should rethink their wildfire policies following the increase in severe wildfires over the last decade that has led to rising costs and damage to lives, property and natural resources, academics argue in new policy brief. 

There has been an increase in catastrophic wildfires around the world over the last few years alone, such as in Portugal (2017), Greece (2018), Brazil (2019) and most recently Australia (2019/2020).

The increased media attention during the devastating impacts in Australia highlighted to the world how shattering wildfires can be and how other catastrophic events have occurred in nearly all ecosystems, from the tropics to boreal ecosystems. 

Consequences

These severe fires have important consequences on people’s livelihoods, human health, climate change and ecosystem services, including forest products, biodiversity, water, soil and air quality.

The vast majority of these fires are mostly due to exceptionally warmer temperatures and anthropogenic causes, such as human set-ignitions, deforestation and creating new land for agriculture.

The rising economic and social costs of fire, particularly in the transition between unoccupied land and urban areas, makes it a priority issue for ecosystem managers and policy makers around the world.

Royal Holloway’s report, Diverse knowledge informing fire policy and biodiversity conservation recommends four steps to improve fire management practices.

Firstly, collect and integrate diverse knowledge. The report suggests using long-term ecological data to assess present fires in the context of the region’s historical fire variability. For example, assess whether wildfires are outside of an ‘historical norm’ compared to past conditions.

Communities 

Secondly, the report suggests that governments set fire management plans based on the diverse knowledge, and set benchmarks for fire regimes, in terms of frequency and intensity that maximise biodiversity and reduce fire risks.

Based on the information from long-term fire records, consider controlled burning in areas where fire has been artificially excluded, and monitor the outcomes. Prioritise traditional burning practices that focus on targeted species to preserve traditional food sources and other ethnobotanical resources.

Governments should raise public understanding for fire by communicating potential risks and educating the public that fire is a natural component in many ecosystems; they should promote the inclusion of traditional knowledge approaches that are collaborative, community-focused, and contribute to the continuation of cultural traditions, intergenerational knowledge transfer, and practical know-how.

Finally, they should encourage the participation of different stakeholders and local communities in a process of intercultural exchange.

Ecological history

Policymakers have a responsibility to maintain the mosaic landscapes that prevent catastrophic fires and preserve both natural and cultural heritage values.

Replacing monocultures with traditional practices (e.g. swidden agriculture, pastoralism) may increase ecosystem diversity and resilience while also achieving increased carbon sequestration targets.

Dr Daniele Colombaroli, from the Department of Geography at Royal Holloway, University of London, said: “If we can make good use of available knowledge, such as ecological history of ecosystems and the traditional use of fire by people, fire management practices will be more effective.

“With that in mind, we recommend that fire management and policy incorporate long-term ecological and traditional knowledge in their evidence base. This would be set against locally and regionally relevant benchmarks for fire regimes and identify targets related to biodiversity conservation and resilience in landscapes, acceptable to local communities.

“Therefore, we have long term ecology and then traditional knowledge as a key source of information. This is especially true of the knowledge from long-term ecology, which can provide baseline information on the variability of fire in ecosystems before modern land use practices, and show how fire responded to past climatic changes.

“Used together, the diverse knowledge from science and local communities can help fire management practices meet conservation targets, mitigate negative impacts of wildfires and engage in efforts of respectful reconciliation with Indigenous and Descendant groups.”
