A study commissioned by the premier online eco retailer     www.e-photoframes.co.uk, written here in Both Thai   and English, has found that the high market price of a particular type of wild mushroom, Hed Thob, and its lucrative allure of potentially doubling a farmer’s yearly income, is one of the main factors underpinning the deliberate setting of forest fires. A phenomenon that, due to the emission of large amounts of smoke containing carbon dioxide (CO2), is a killer of people and tourism and is also one of the most significant causes of climate change.     A dairy crop farmer from the north of Thailand, Khun Som, states that, ‘We normally use fire in the forest because, sometimes, it’s hard to walk and find the things we want to collect. We do not hesitate to use it to burn small areas. A fire that accidentally gets out of control can sometimes happen, but such fires often extinguish themselves…..’   Alex Putnam, the leader of the research project, states that, ‘The use of fire during the dry season for the collection and propagation of forest products, particularly mushrooms, is a tradition which has been practiced for many decades, and which sustains the livelihoods of local farmers in northern Thailand. However, due to annual burning, the forests are becoming degraded and devoid of all life, and local urban areas are being plunged into a haze of suffocating smog. The degradation of dry forests, (dry diterocarp),  in northern Thailand, due to the use of fire , is also limiting  the capacity of the forests to naturally sequester carbon dioxide emissions, therefore exacerbating the issue of climate change’.     The aims and objectives of the study are to explore the causes and effects of deliberate burning within the province of Chiang Mai, northern Thailand. In addition, the project also proposes solutions to deal with the traditional practice of burning in the province, and sets out a fire prevention plan for 2010 and beyond. The project uses both quantitative, (fire data collection), and qualitative, (semi-structured interviewing), research methods. In total, during the two month study period, the project recorded a total of 58 fires, the majority of which, (36%), occurred within forests, open areas, (19%), and along roadsides, (17.5%), whilst domestic,  (15.5%),. and agricultural fires, (12% ), recorded the lowest percentage. For further Information please contact Alex Putnam - putnamalex@googlemail.com  �

The following blog is an account of a recent trek into the forest reserves of Mae-On district, an area of Northern Thailand where I’m carrying out a study into the ‘Causes and Effects of Deliberate Fire Burning’ – a phenomenon that occurs every year during the dry season (Nov-April). The clearing of land for agricultural activities and the collection of forest products such as wild mushrooms and herbs are believed to be some of the key factors underpinning fire in the local region. So as to gain a clearer insight into why the fires are happening we arranged to meet with a local farmer called Khun Som (Mr Som) who had kindly agreed to take us on a tour of the local forests…. 

Wednesday 11/03/09

10.00am Alt – 424m

Rendezvous with Kun Som – a local Dairy/Arable farmer who also uses the forest for hunting and collection of forest products.  

We begin the trek from the local temple  (The trekking group consisted of myself, my research partner Bjarke, Did the translator and Kun Som).

As soon as we walked into the forest area behind the temple it was clear to see that the area had been extensively burnt, scorched black earth spread out all around us. Bjarke made the point that a fire so close to a religious monument must have caused considerable concern. A concern that has no doubt been part of the religious community for many years as Khun Som tells us that fires are a yearly practice to help clear the land so as to make it easier to collect forest products such as Mushrooms, Herbs and Bamboo Shoots. He goes onto state how “some fires can get out of control and burn larger areas than intended” as is the case with the land near the temple.

11.00am Alt – 478m 

Trekking through a dry Dipterocarp Forest - a forest type that grows in the driest and most degraded areas, from the valley bottom up to 800m. Forests of this type shed their leaves during the dry season so as to retain water due to the limited ground source availability. Therefore, the forest floors become inundated with leaf litter and easily prone to fires. It was clear that a fire had occurred recently as all that lay beneath us was the ash of burnt leaf litter. Whilst walking through this section of forest Kun Som demonstrates the types of wood harvesting techniques he uses. Despite the strict laws banning any wood collection from Thai forests Khun Som still collects wood, as he feels there is little chance of him being caught by the authorities.

As we walked on it soon became apparent that this forest was of a degraded nature, not just because of the lack of leaf litter and stunted tree growth, but also because large clumps of Bamboo began to merge with the forest until they were in fact the dominant species. Bamboos are essentially giant grasses and therefore highly effective competitors. In a forest such as this, that has been burnt annually, fire resistant Bamboos tend to take over to the point where all you have is large swathes of Bamboo and not much else.

The following picture illustrates how tree bark is stripped for the use of fire kindling, such practices can stunt the growth of the tree, making it weak and therefore prone to being blown over in gales. (Notice the approaching Bamboo clumps in the background)

12.00pm Alt – 475m

Reached a clearing in the forest where we took a break and assisted Bjarke in removing the spines of a caterpillar from the palm of his hand, a scenario that if not dealt with correctly could lead to excessive itchiness!

The area in which we had come to rest had an eerie feel to it, almost warlike as if it had just been ravaged by a napalm bomb! The only signs of life being the vivid sight of new grass shoots that were sprouting out of the blackened soil. Such a sight reminded me of the burnt roadside verges that too had became colonised with new grasses, which act as perfect grazing areas for cattle. No doubt in a few more weeks the cattle will also be up here enjoying a fresh pasture of grass. 

13.00pm Alt - 640m           

After an hour of arduous hiking we finally reached the highest point of the trek. The forest type was still Diptereocarp, but due to the high altitude was less disturbed by Fire. Khun Som explained how fire tends to be started at the base of hills and as we had experienced the almost vertical climb up here is enough to deter even the hardened fire-starter and therefore lessening the impact of fire at higher climbs. The fact that we were also on the edge of a National Park may also have something to do with less fire activity as such areas are protected by a more comprehensive fire prevention strategy than forest reserves.

14.00 Alt 550 – 500m

On our decent the familiar sight of scorched earth returned and with it an emergence of Bamboo forest. However, much to our surprise, the clumps of Bamboo suddenly began to diminish and we entered into what can only be described as a less degraded forest- large towering trees of a height of 30 m +.  It turned out that this area was part of Khun Som’s village and was in fact under going a fallow period in which nothing within the forest is to be disturbed. Such rules and reg’s are common amongst villages, they are part of local law, that isn’t always recognised at the national level, but is practiced amongst villages. The effectiveness of such agreements differs between villages some strong and some weak. The forest that I was now stood in had some of the most well kept trees I have seen whilst carrying out this research. The only set back was the usual presence of blackened earth due to uncontrolled fires lit in the neighbouring area. Whilst in this part of the forest we hear the distant sounds of gunshots, Khun Som knows that hunting is illegal in Thailand but just like the wood collection, there is little in the way of enforcement.  Although he isn’t hunting today his usual catch will consist of Jungle Fowl, Squirrel and sometimes, if he is lucky a Wild Boar. Fire is sometimes used to drive out animals from the forest, but Khun Som says that he doesn’t use fire to hunt.

15.00 Alt – 550m

Whilst walking through the fallow area we began to hear the distant sounds of a running stream. As we approached the flowing water a distinct transition occurred, the burnt earth gave way to copious amounts of leaf litter and small saplings. Unaffected by the threat of fire the canopy became a lot more vibrant, vivid greens, creepers and birdlife abound all around us- such an experience illustrated how the presence of flowing water can dramatically effect the health of a forest. It was as if we had discovered an Oasis. However, the experience was short lived, moments later I looked to the left of me and saw smoke rising from the forest!

Bjarke and myself hastily walked in the direction of the smoke and as we got closer, we were greeted by an enormous fallen tree that had naturally uprooted itself due to the poor condition of the soil structure beneath it. A fire was rapidly taking hold of the fallen tree which we weren’t sure how it had started. One assumed that the area had been set alight so as to clear around the tree to make it easier to harvest its woody bulk. We stood and watched in awe, as the fire grew larger and larger, eventually engulfing the majority of the fallen tree. For some reason Khun Som was reluctant to come and see the fire and so our queries about the fire were left unsolved.  

15:30 Alt – 456m

We eventually emerged from the forest and began walking across the terraced paddy fields which at this time of year are either full of vegetable crops or left fallow awaiting the rains of the South West Monsoon.

Then all of a sudden, just when we thought we had seen enough degradation for one day, Khun Som kneeled down on the path that we were walking along and lit the verge, astonished, yet again, we looked on helplessly as another blaze took hold! The land which Khun Som was burning was his own and he said that he wanted to clear it so as to plant a crop of maize for his dairy cows and that this was the quickest and cheapest way to do it. Unlike forest fires, which are outlawed in Thailand, if you’re a farmer with the correct land tenure documents burning isn’t illegal. The best thing local authorities can do to manage the situation is advise farmers against burning or at least practice controlled burning. In this case Khun Som, having lit his land, walked on back to his home, leaving the fire to tend to itself.  

Fire in Thailand and the greater S.E Asian region has been practiced for centuries and farmers like Khun Som see it as a crucial part of their livelihoods. Unfortunately though a practice, which some consider to be of benefit, is also becoming a serious cause for concern for others. For the last few years the low lying city of Chiang Mai, due to it’s geographical location- surrounded on all sides by rugged mountains- has become engulfed in a haze of smoke, a scenario that reaches its peak in March. Along with the peak in smoke haze comes a peak in hospital admissions due to respiratory related problems. Such a smoke haze also effects the local economy as it deters tourists from visiting the region.

When asked about his opinions of the people who complain about the smoke, he simply states that;  “It’s just our way of life, we have used fire for many years. The issue about smoke is a recent occurrence due to the late rains and hotter air temperatures. It doesn’t last forever. When the rainy season arrives the conditions will improve.”

The last blog that I posted explained how fires in the Northern region of Thailand are depleting soil fertility and stunting the growth of forests. However, since then I have witnessed a separate phenomenon, which has me somewhat stunted too-Fire Induced Growth.  

Having witnessed first hand, fires burning and the scorched black earth left in its path, one would think that little survives. However, on recent observations I have been struck by the presence of a verdant blossom of greenery beginning to colonise the charcoal patches of burnt ground that were ablaze no less than three weeks ago. 

The picture below shows an area of land at the end of burn.  

The following picture is the same area of burnt land, but three weeks later, notice the green shoots.

Having done some digging around I have managed to come across some previous literature on the reasons for such re-growth.

Certain areas where burning has occurred contain a specific type of grass called Imperata Grass, a grass that when in it’s mature form has little nutrient value. Therefore, local cattle grazers prefer to burn back the old grass and, due to the grass’s fire resistant nature, new shoots produced on burnt areas have a higher nutrient value, which is perfect for grazing cattle on. (Hoare. P, 2004)

Such an activity is widely practiced in Mae-On as there is a large amount of cattle farming, but unlike cattle farming in Europe where paddocks/fields are used for grazing, cows in Thailand appear to be given the rough end of the ‘verge’, so to speak. They have to forage alongside roads and other areas of less fertile importance, whilst the larger open spaces are prioritized for the cultivation of Rice and other, more lucrative, cash crops. Such grazing practices have been practiced for many decades, and fire has no doubt been an intrinsic part of feeding cattle, but maybe all that is called for is a new growth encouraging practice, cutting back the grasses using a manual method and not fire.

More often than not the areas where cattle are left to graze are under the jurisdiction of the highway department or other local government agencies. Therefore, such agencies could carry out an effective campaign which equips local farmers with both the tools and the financial means to carry out roadside clearing without the use of fire - Lawnmowers, Strimmers, Scythes all could be brought to arms so as to clear out the old grasses and allow new shoots to burst into life! Yes, it would involve more labour, but if the farmers are able to earn an income from clearing the verges whilst at the same time providing fodder for their herd, then surely the allure of burning would, indeed become stunted and manual clearing a more widely practiced activity.

The recent forest fires in Victoria state, Australia have shown the world just how severe forest fires can be, in the S.E state temperatures have soared to nearly 50 degrees causing the tinder box forests surrounding Melbourne to ignite into ferocious fireballs destroying everything in their path, including the lives of nearly 200 people. Such tragic circumstances, have quite rightly gripped the attention of the global media- 24hr coverage of the Australian Bush fires and the fight to try and extinguish them has given the world a whole new perspective on the challenges posed by fire. However, it is worth noting that other countries, although maybe less ferocious, are also in the grip of a fire burning season too. Northern Thailand being no exception, presently it is the dry season and with a lack of rain and rising temperatures the conditions for fire burning couldn’t be more appropriate. 

The region in which I’m undertaking my research - Exploring the reasons and consequences of deliberate fire burning during the dry season in a district of Thailand so as to prevent/minimise the amount of fires occurring in the region -

 is called Mae-On, which is located 30km due East of the Northern Thai City of Chiang Mai. The average altitude is 400m and the forest type is dry deciduous (Trees which drop there leaves during the dry season so as to retain water) a natural occurrence that is a necessity, but also in terms of fire, a hindrance. When leaf mould falls from the trees it becomes an instant fire hazard as the leaves tend to be dry and easy to ignite. If left in their natural state the leaves would naturally rot back into the soil and replenish the soil in the form of mulch. However, from my recent observations and interviews with the locals, farmers don’t see it in the same way and prefer to clear such areas to keep the area tidy and controlled and therefore the fastest and cheapest way to clear such leaf cover is to burn it.

For the last week this is the main type of burning that has been taking place, to the point where by large expanses of blackened scorched earth leading out from the roadsides becomes the norm.  Unfortunately, although cheap and fast, such burning is actually detrimental to the soil quality as studies in the local area have shown that frequent fires reduce both density and species richness of the tree seedlings community. Fire also burns off soil organic matter, which in turn reduces the soil’s moisture retention capacity.

  As well as roadside Fires I have also witnessed the burning of agricultural crops, particularly Rice Paddy Fields. I am told that this is due to the fact that by burning the crop, ash left over from the burn nourishes the field and prepares the soil for the planting season. However, burning such crops is actually detrimental to the soil as it reduces key soil nutrients such as potassium, calcium and magnesium as these are lost as fine particles in the smoke, whilst nitrogen, phosphorous and sulphur are lost as gases.

.

Therefore, having witnessed first hand the destructive fire in Thailand as well as viewed, from a safer distance, the Australian Bush fires, I feel that there needs to be a stronger sense of urgency to prevent fires from taking place in Thailand. At present Thailand’s fires are due to traditional agricultural practices, practices which take along time to change. Coupled with this is the fact that the local authorities have poor resources-lack of law enforcement and public awareness- all of which leads to fire prevention being tackled, at best, with a lack-lusture response and at worse tolerated. 

The devastating impact of Australia’s recent fires should come as a wakeup call to Thailand and other countries that are grappling with the issue of fire. Given the potential threat of Climate Change and rising temperatures it may only be a matter of time before Thailand and other S.E Asian countries practicing fire burning, are having to fend off their own unexpected and uncontrollable blazes similar to those experienced Down Under in recent days. 

Each year, during the Dry Season Jan-April, the hills of Northern Thailand are ablaze with fires. Hunting, Land Management and Mushroom collecting are believed to be some of the main reasons behind the fires, such a scenario leads to towns and cities becoming clogged with smoke pollution causing all manner of problems, effecting local economies, human health and essentially the health of the forest.   

So as to understand such a phenomena www.ephotoframes.co.uk is commissioning Alex Putnam to carry out a two-month research project, studying Forest Fires within the region of Chiang Mai - North Thailand. The Purpose of the study is to ‘Understand the Reasons and Consequences of deliberate fire burning during the dry season in the Mae-On district of Thailand, so as to prevent/minimise the amount of fires occurring in the particular region’. 

Mae On is a small district 40 KM East of Chiang Mai, an area that is often fraught with forest fires during the dry season due to the reasons given above. Alex will be working with both local villagers as well as the local administrative bodies so as to collectively come up with a comprehensive fire prevention plan, which highlights both the current problems associated with fire as well as the ways in which fires can be managed in a more sustainable way. The project will also illustrate how forest fires are one of largest causes, but least discussed causes of climate change*. 

So as to keep up to date with Alex’s exploits, he will be posting regular blogs on this website of his trials and tribulations and other fascinating experiences that he will no doubt encounter over the next two months starting from the 1^st of Feb 09 Onwards. 

*Once the report has been completed it will be published on the e-photoframes website.

  The recent political siege of Suvarnabhmi airport in Thailand’s capital should not just come as a shock to the many stranded tourists and Thai businesses and enterprises that were affected by the occupation, but also to the global community as a whole. Such a phenomena could, potentially, become the norm not necessarily due to political upheavals, but because of the simple fact of a global peak in oil production. 

In a recent interview with George Monbiot http://www.guardian.co.uk/environment/series/monbiot-meets Faith Birol, chief economist of the International Energy Agency, when asked to give a precise date for Peak oil production stated that: -

  Therefore, based on the IEA’s prediction that gives us just 11 years to overhaul our current energy infrastructure, a feet that although widely talked about (The ‘Green Economy’) is still lacking in action. In terms of the aviation industry research and development has lead to a significant increase in the efficiency of fuel consumption. However, the search for alternative fuels has been less rewarding. A recent paper produced by Boeing simply entitled ‘Alternative Fuels for use in Commercial Aircraft’ states that

Despite such hard rhetoric the search for alternative fuels is fraught with obstacles and impracticalities, whether it’s bio fuel and the controversial issue of converting and clearing large swathes of land in order to grow crops for fuel and therefore competing against crops grown for food or how to store the large amounts of Hydrogen needed for long distance flights, the road to a more greener/low hydrocarbon future isn’t straight forward.

The report also discussed the use of algae as a viable source of bio-derived fuel as it has the potential to produce 10-20,000 gallons/acre/year. A production rate that could produce 150-300 times more oil than a crop of soybeans and in the process take up a lot less land space, for example, if the global fleet of aircrafts were to be replaced by algae grown bio jet oil then the amount of land needed to grow such an amount would be the same size of Maryland State in the USA.

Such advances in bio-fuel are considered to be mid-term measures so as to wean the aviation industry of its hydrocarbon addiction. In the long term the aviation industry will be exploring the potential of liquefied gaseous fuels such as hydrogen and methane and how best to store and utilise such fuels.  Nonetheless, despite such advances in alternative fuel research, the Boeing report is rather vague about the timeline needed to implement such forms of new technology, stating that bio fuels such as algae may take between 10-50 years of development before it is commercially viable. However, one thing they are sure of is that in order to kick-start such a green economy, what is needed is a complete overhaul of the current hydrocarbon energy infrastructure a transition from oil to greener/low carbon alternatives.

It seems that, although the research and development of alternative fuel is happening and new technologies are being devised, we are still not acting fast enough to counter act the eventual decline in oil supplies.  No doubt part of this reason is because we have been living in a so called oil-bubble where oil is abundantly available, coupled with this there is also a lack of will amongst global leaders to begin the dramatic changes needed to transform the current energy infrastructure. The Oil is still available, why change? But if the words of Faith Birol are anything to go by, then I fear, because of our unwillingness to begin such a change, come 2020, due to dwindling supplies of oil, such luxuries as long haul flights, may not be so widely available and like those stranded in the Thai Capital at the beginning of this month, people’s mobility will be curtailed not just for a week but indefinitely.

This is obviously a worst case scenario, but it’s worth bearing in mind that the world we live in today is so interconnected that if travel were to be abruptly halted due to a ‘Fuel Crisis’ then it wouldn’t just be tourists that would suffer, but the world as a whole, trade, business and recreation. The global web of communication that we have spun for ourselves could easily become tangled and redundant. Therefore, in order to prevent such a crisis from unfolding it is either now or never, the next 10-15years are critical and should be seen as our final push towards a more sustainable low hydrocarbon economy.

..but Christmas trees don’t have large leaves that create a flamible blanket during the dry season of many semi-tropical regions. e-photoframes is pleased to announce that it will be sponsoring a scientific report on the seasonal burning of forests in the Mae-on region of Northern Thailand. More details will be announced when the contractural details are finalised, but the plan is to produce a survey which is of gloabl signficance, both in the fields of climate change and regional economic impact. This report will be a welcome addition to our reports on airline emissions (now being used all over the world in scientific papers) and climate change reporting.

Yesterday I took my two young ones on the train to London. Apart from the usual train spotting (I hope they will grow out of this), tower blocks were added to our game of eye spy. It was a grey old day in London, and I imagined that the vista from one of those blocks must be depressing. Endless dreary grey. When you think about it, this is true wherever you live: If you are looking out on grey skies the view doesn’t get much worse.

 I have to declare this is not a new thought. Ever since I bought my first flat, I have ensured that the view is either green (ideally mature trees) or at least not grey. We have even built a house and planted 1,000 trees partly to ensure we get a view of the treetops. And that brings me to Christmas trees. As deep winter dawns and most trees shed their green, what better way to cheer up the living room than bringing the ideal view inside!
