#642: Wildfires

Wildfires are breaking out across Europe.

It's not clear whether most of them started by natural causes.

A report from the House of Lords.

Wildfires are a natural phenomenon and an essential process in some ecosystems. However, around the world climate change, demographic changes and shifts in land use are altering their frequency and severity.

In the UK, natural wildfires, for example those sparked following lightning strikes, are rare and most wildfires are the result of human action. The National Fire Chiefs Council (NFCC), which represents fire and rescue services (FRS) across the UK (44 in England, three in Wales and one each in Scotland and Northern Ireland), notes that most wildfires nationally originate from human activity such as:

• littering (from improper disposal of a cigarette to dropping litter such as reflective items and glass bottles that then start a fire)
• unattended fires (campfires, bonfires and barbecues left unattended or not fully extinguished)
• deliberate fire-setting
• controlled burning used to manage land that then gets out of control

There is no single definition of what constitutes a wildfire in the UK, with different definitions used by government agencies, the media and FRS. 

The UK government used to define a wildfire as any “unplanned and uncontrolled fire(s) in the natural environment”, but now defines the term to mean an “uncontrolled fire that burns vegetation, such as grass, heather, woodland, crops and scrubland”.

The NFCC maintains that not all outdoor fires are wildfires. Instead, it defines a wildfire as “any uncontrolled vegetation fire which requires a decision, or action, regarding suppression”. In addition, the NFCC specifies that a wildfire will meet one or more of the following criteria:

• involves a geographical area of at least one hectare (10,000 square metres)
• has a sustained flame length of more than 1.5 metres
• requires a committed resource of at least four FRS appliances/resources
• requires resources to be committed for at least six hours
• presents a serious threat to life, environment, property and infrastructure

One of the most heartbreaking ones, was relatively local to me, and an area I know well: Dunwich Heath which borders Minsmere RSPB reserve.

A fundraiser shows the depth of feeling for this landscape.

"This beautiful purple landscape, once filled with the sound of warblers and skylarks and people enjoying a walk through the heather, is now unrecognisable."

#395: Hansard Debate

Thanks to Green Party Leader Natalie Bennett via the GCSE Natural History twitter feed for sending a link to this Hansard debate.

Questions were asked about the GCSE Natural History and what progress was being made towards it. Search under Natural History / Geography to find some interesting statements and quotes:

Baroness Bennett of Manor Castle

We have inherited a disastrous set of values and attitudes towards the environment, with thinking that goes back a long way and which we have adopted into our intellectual tradition. It includes the great chain of
being, which is the concept that human beings are some kind of pinnacle of life, and the idea that the whole complexity of life on earth—the living system that James Lovelock identified as Gaia, which has evolved over billions of years—is there for us as a species, under our control and for our exploitation.

The 21st century has exposed that for the dangerous fallacy it is, with the climate emergency, the nature crisis and the poisoning of our planet with novel entities; six of the nine planetary boundaries have been exceeded. We know that there are other intellectual traditions and other ways of looking at the world, which are attracting attention from our scientists and researchers. For example, I note that, across many African religions, there is the concept of ukama, which states that animals are part of a community with humans; it emphasises mutual dependence, a sense of unity and, at least sometimes, a moral imperative of respect.
