Adding Fuel to the Fire: Australia’s Heatwave and Bushfire Epidemic

January 21, 2013

Bushfire in Kakadu National Park, Northern Territory, Australia by Thomas Schoch.  This file is licensed under the Creative Commons Attribution-Share Alike 2.5 Generic licenseWhilst the UK suffered its wettest summer in 100 years and is currently under a blanket of snow, pictures showing the devastating effects of the epidemic of bushfires that have hit Australia, linked to a record breaking heatwave this January, have been appearing in the news.  In The Observer last Saturday, Alison Rourke reports how firefighters are struggling to control what have been described as the “most atrocious fire-fighting conditions in 30 years”.  A combination of high temperatures and strong winds have resulted in the situation being given a fire danger rating of ‘catastrophic’, the highest possible rating.  In a special climate statement released by Australia’s Bureau of Meteorology (BoM) on Monday, the heatwave event is described as being persistent and widespread, affecting large parts of central and southern Australia.  The combination of dry conditions since mid-2012 and a delay in the monsoon are thought to have exacerbated the susceptibility of the landscape to bushfires.

While Tim Flannery from The Guardian argues that these “raging wildfires are forcing many to rethink their stance on climate change”, the immediate focus is largely on the improvements in communication, weather prediction and management of the outbreaks, particularly since the tragedy in Victoria in 2009 where 173 people lost their lives.

In a paper for Geography Compass, Christopher O’Connor, Greg Garfin, Donald Falk and Thomas Swetnam review trends in human pyrogeography research, where they discuss the interactions among of fire, climate and society.  In particular, they highlight that geographers have the necessary tools to “change operational management actions and societal preparedness” and advance the study of the complex nature of pyrogeography.  They investigate, among other themes, the frequency and extent of wildfires, the role climate plays as a driver of fire occurrence and the impacts of human modification of the landscape; however, they emphasise that our current understanding of the interactions needs to be improved if we are to predict what might happen in the future.  Whether you believe in climate change or not, it seems that there have been more and more extreme weather events hitting our headlines over recent years; however, as the understanding of the complex relationships among fire, climate and society improves, hopefully society will become increasingly more prepared to deal with them in the future.

Pests, Pathogens and Passports

If you have ever visited Australia you will have experienced a force to be reckoned with- the Australian Customs and Border Protection Service; woe betide anyone who forgets the piece of fruit squashed at the bottom of their hand luggage!  Few places exist where the importance of biosecurity is more prominent to the general public than in Australia’s airports where strict regulations are imposed on the importation of food, plant material and animal products to minimise the risk of exotic pests and diseases entering the country.  Whilst public awareness campaigns of biosecurity issues are common in Australia, in the UK it appears that both public and governmental awareness only increase after the damage has been done.

Over the last few weeks, Chalara fraxinea, or ash dieback as it is commonly known, has dominated the news.  This virulent fungal disease is thought to have hitched a lift with imported saplings from Europe and has already been confirmed in over 80 locations (Forestry Commission, 5th Nov).  Patrick Barkham from The Guardian questions whether more could have been done to prevent this outbreak and criticises the government for the “apparently sluggish response” to the disease.  As fears grow over the future of our woodlands, more threats from foreign pathogens to our native species are coming out of the woodwork, with Robin McKie from The Observer warning that the Scots pine “could be the next casualty of a ‘tidal wave’ of tree diseases”.

However, it is not just the plant kingdom that is under threat.  The controversial badger cull to prevent the spread of bovine tuberculosis (bTB) has recently been discussed in parliament.  In an article for The Geographical Journal, Gareth Enticott, Alex Franklin and Steven Van Winden explore different biosecurity strategies and behaviours practiced by farmers in response to bTB.  Their findings suggest that the promotion of biosecurity to farmers should draw on locally situated practices and knowledge rather than taking a standardised approach.  They argue that policy-makers need to “re-evaluate the purpose of disease control and their approaches to it”.

It has taken a series of pest and disease outbreaks for the seriousness of the UK’s biosecurity to hit the headlines.  Lessons can be learned from the Australian approach but as more reports emerge, claiming that the government was aware of the ash dieback invasion three years ago, perhaps more focus is needed on biosecurity risk assessments rather than on mitigation efforts once the problem has taken hold.

Local solutions to global food shortages

January 21, 2011
Mopane Caterpillar

A Mopane caterpillar, found in southern Africa

I-Hsien Porter

The United Nations ‘Food Price Index’ recorded food prices (particularly cereals, sugar and meat) rising to record highs.

Warnings of dangerously high food prices were driven by dry weather in Argentina, cold weather in Europe and North America, and floods in Australia. For example, Australia is the world’s fourth largest exporter of wheat.

However, our attention is rarely drawn to food consumption, rather than food production. In a paper in the Geographical Journal, Peter Illgner and Etienne Nel highlight the loss of traditional food and food consumption, which in many parts of the world has been displaced by imported Western fare.

In a case study of the Mopane caterpillar, the authors argue that edible insects have historically been important to diet in poor rural communities. If bias towards Western foods could be overcome, Illgner and Nel express the view that insects are an economically and practically viable addition to our diets. In addition, this might even empower poor communities that cannot aspire to lifestyles associated with high levels of consumption.

Climate Change; Mitigation and Adaptation

September 18, 2010

By Paulette Cully

Coming across a news article from the BBC about geoengineering to compliment the mitigation of climate change, I was fascinated to read about the almost science-fiction like techniques which have been proposed. These range from (to name just a few) limiting incoming solar radiation through the injection of SO2 (sulphur dioxide) aerosols into the stratosphere to launching giant mirrors into orbit to reflect some of the incoming sunlight away from the Earth. However, some scientists feel that even though the technology is feasible, these measures are inappropriate because no one knows if they will work or even if they will have any adverse effects. In addition, the techniques would only treat the symptoms of climate change, would have a limited impact and would leave the greenhouse gasses in the atmosphere for future generations to deal with.

Interested to find out more about responses to climate change, I read the recent journal article in Geography Compass, by Sposito et al who explain that there are two broad categories of reaction to climate change; mitigation and adaptation. Synergistically, mitigation and adaptation activities are essential to maximise the benefits and minimise the costs of responding to climate change. Mitigation has a global benefit and in the main is dedicated to reducing and eventually halting greenhouse gas emissions. However, research indicates that this will not prevent the Earth’s climate from changing within the next few decades.  Therefore, adaptation, which acts on the local and regional scale, is important and unavoidable.  In their article, Sposito et al describe the adaptation issues which relate to Australian agriculture because it is very susceptible to the adverse impacts of climate change. With major shifts in temperature and rainfall predicted for the future, strategies can be formulated to recognise regions under threat of productivity declines and identify alternative crops better suited to future climatic conditions.

Red Sky in Australia

Sydney Dust StormBy Clare Boston

Last week, dust storms in eastern Australia caused havoc to populated coastal areas, diverting flights, disrupting ferries and causing long queues on major roads.  The dust originated from the Lake Eyre region following the movement of a cold front and strong winds eastwards over the area.  Dr Craig Strong from Griffith University, Queensland suggests that a combination of floods, drought and strong winds caused the latest dust events, where sediment deposited by flooding earlier this year, dried out and became available for aeolian transport.  Widespread drought in southern Australia over the last 10 years is also likely to have been an important factor in increasing dust availability due to a reduction in vegetation cover.

In Geography Compass Heather Viles reviews the affect of biological crusts on arid landscape dynamics.  Biological crusts consist of a variety of micro-organisms and lower plants that can play a key role in trapping and retaining dust, providing stabilisation from surface run-off and wind erosion.  The impact of climate change has not been widely researched, but it is likely that changes in precipitation patterns and increases in CO2 have had significant effects on crust stability.  As well as a reduction in vegetation cover, the increased frequency of extreme flood and drought events in Australia may have caused a reduction in the performance of biological crusts as a mechanism for dust retention, thus contributing to the increased availability of dust in the Lake Eyre region.

Drought – the world’s dominant natural hazard

August 24, 2009

Drought_Swimming_HoleBy Troy Sternberg

Texas and Australia are experiencing extreme droughts that have not been seen for a half century or longer. Amid much press coverage government efforts to mitigate drought range from no water for gardens to aid, emergency loans and town prayer services (yes, in the U.S.). Drought is the world’s dominant natural hazard, thus can be no surprise in dryland regions. The severe impact comes from human efforts that are often inappropriate to the environment – farming in the desert, large populations where there are limited resources, the desire for swimming pools and green lawns in scrub land. The last century has seen myriad attempts by man to conquer the desert. Great effort and expense have made miracles happen, but these are temporary victories dependent on ever-increasing external inputs for success. For long-term survival in the desert we should look to the indigenous dwellers – camel, cactus, or lizard – and treat water as a scarce resource, maximize efficiency, and limit extraneous effort. Until this is learned human extravagance in arid lands will persist and the physical and economic effects of drought will continue to alarm us. Nature makes drought endemic, it is we who must adapt – the sooner the better.
