Forest Fires and Smoke Haze in Southeast Asia

What are the Sustainable Pathways for the Future?

by Tim Frodsham, Peter Newman and Harry Harsono Amir

Introduction

This study examines the effects and causes of what was billed morbidly by the world's media as Asia's worst environmental disaster.

It looks at the socio-economic and environmental impacts and the ways in which such human-made catastrophic events could be averted, invoking sets of strategies aimed at sustainable solutions that are workable.

It also asks the reader to consider the discussion questions, which are designed to stimulate constructive dialogue concerning the issues at hand.

Between late July and October 1997, over 1.7 million hectares (17 000 km2) of Indonesian tropical forest was estimated to have gone up in smoke. Massive forest fires in the Sumatran provinces of Jambi, Riau and elsewhere in Indonesia caused an enormous and debilitating smoke haze that hung over the Southeast Asian region, drifting as far as an area between Bangkok, Kuala Lumpur and Singapore, Manila and Irian Jaya. The smoke even reached Darwin and India, though only briefly.

Not all the destruction occurred in Indonesia; around the same time, fires of lesser proportion were also reported to exist in the East Malaysian province of Sarawak, where large areas of land have continued to be logged and burned over recent years.

Fanned by a drought thought to be caused by the El Niño effect's climatic disturbance that year, which had delayed the wet season rains by up to several months, the forest fires were not extinguished at the time normally expected. Dried peat bogs in the normally waterlogged lower lying areas also ignited, and smouldered unabated alongside the burning trees. The severe drought also meant difficulty in procuring water to combat the fires in the worst hit areas.

Socio-economic

Only very few people were reported to have died from respiratory problems as a result of the fires, but the true long term health effects of the millions of people living in the areas worst affected will not be ascertained for many years to come.

Health experts stated that breathing the air in the worst affected areas of the smoke haze was equivalent to smoking up to 80 cigarettes a day. Irrespective of any differing concerns between the ASEAN countries of what was an 'acceptable' level of exposure, the levels of particulates and pollutants (mainly carbon, nitrogen and sulphur dioxides) from the haze in worst affected areas such as Pontianak, in West Kalimantan, had reached levels of 1890 µg/m3; frighteningly distant from the United Nation's World Health Organisation's guideline that atmospheric concentrations of suspended particulate matter should not exceed 90 µg/m3 (Potter 1997). A health risk analysis could be done on these data, similar to those done on air pollution.

Serious transport accidents appeared to have been more than co-incidental during the smog period: a Garuda Airbus collided into a mountainside on the approach to Medan in Sumatra, killing all 256 passengers on board. Shortly afterwards airports were closed at Medan and at other terminals in the country.

Meanwhile, in the unclear straits of Malacca, a small Indian cargo vessel hit a large supertanker, killing 20 of the former ship's crew. Many traffic accidents were exacerbated by the haze.

In Indonesia's eastern most province of Irian Jaya, severe drought had caused staple food crops to fail in the highlands, resulting in an estimated minimum of five hundred deaths from mass starvation. The death toll was reported to rise as smoke haze from extensive fires also burning in this mountainous province hampered visibility and access by aeroplanes directed at providing emergency food relief. A regional news report alleged some 90,000 people were reported to be facing imminent starvation from the continuing famine in mid-November, when the first wet season rains had not fallen, and the fires and associated smoke haze continued.

The economic implications were immediate and are expected to be long term. Tourism in the entire Southeast Asian region dropped off considerably in combination with the stock market decline. Indeed, it is possible to see a link between the loss of economic confidence and the smoke haze issue. Many previous hotels and holiday bookings were cancelled in Malaysia and Indonesia especially.

As the haze endured in Malaysia, increased reports of haze-related depression and even suicide began to appear in the midst of the continued grey-black lightness and dark normally associated with the extreme winter period in the higher latitudes. The compounded impact of all these incidents forced the Indonesian Government to declare a national disaster, and open its doors to international assistance. The co-incidence of Indonesia appealing to the global community for help on their currency crisis and their ecological crisis is of considerable interest to those examining the issues of sustainability; the environmental and the economic are linked inextricably.

Environmental

Not suprisingly the impact on wildlife was catastrophic. Potter (1997) reported that a fire in the Kutai National Park (East Kalimantan) led to the death of 30 female orangutans. Villagers were said to have chainsawed to death the adults and captured the infants for sale or adoption as pets.

Great areas of forest were destroyed in other National parks causing other large mammal species to flee from their destroyed habitat, including a herd of some 1800 elephants. Numbers of deer were also seen making themselves easy prey to hunters. Tigers driven from the forest by the fires, attacked and killed two people in Sumatra. Species extinction rates are difficult for tropical ecologists to calculate at any time, but are impossible to estimate in the aftermath of the inferno.

The majority of extinctions would have occurred to organisms whose existence is critical to the functioning of tropical ecosystems: the large number of invertebrates in lower trophic levels of the food chain. Also phenomenal was the massive increase in CO2 emissions (in tonnes of carbon per km2) from the vast area of forest that was incinerated.

Causes

From most of the literature and commentary on the issue, it appears that the majority of the burning was done by people contracted to large Indonesian forest plantation and palm oil estates, in areas designated for clearing. The next major contributors were logging companies who clear land for timber extraction. Thirdly, and least culpable of all were the small scale shifting cultivators, who seasonally burn small plots for their subsistence.

Media reports were made by the large timber and rubber cartels, who claimed that the fires were lit by itinerant shifting cultivators from villages. The facts suggest that the vast majority of the fires were lit by those logging and plantation estate workers routinely contracted by the cartels. High resolution satellite imagery from Singapore University's Remote Sensing Institute (CRISP), showed many of the fires in the vicinity of large corporate timber concessions and plantation estates.

There remains some confusion however, as dispossessed farmers whose land had been taken without compensation by the big plantation and timber barons, also lit fires inside existing estates in angry retribution.

Other fires were lit to make way for the Indonesian government's agricultural projects in Kalimantan for rice cultivation by transmigrants from other overcrowded islands in the archipelago, the majority from Java. This necessitated the clearing and burning of forested land.

The majority of fires were thus part of a normal process, but because of the very dry conditions it was easy to remove unwanted bio-mass by burning. Moreover it was so easy for such burning to escape into surrounding areas. The reality is that burning of the land is the only means presently seen to be acceptable by land managers (large and small) to clear land. ASEAN countries such as Malaysia and Singapore were eventually powerful in their denouncement of the Indonesian Government's handling of the issue. However, in the early stages of the issue, before the general public became incensed, they were patient with Indonesia when questioned by the media about that country's slow response to the disaster. This may have been cultural reticence to criticise close neighbours or it may have been that Malaysian and Singaporean business interests were also vested in the large estates that suffered ignition.

Potential Solutions

Causative factors and potential solutions for the problems suffered may be classified under the four different categories: socio-economic, physical, biological and climatic. Each will be discussed in turn.

Socio-economic

Lack of education of local people and officials results in mis-informed views of the true extent and nature of the fire and smoke haze problem. Improved education about the issues combined with more media coverage would result in more informed assessment and facilitate positive local action.

Burning off was the most economically efficient means of land clearing to expand plantation output and maintain swidden cultivation. Alternatives to this need to be examined, including ways of making existing land more sustainably productive, including, inter-cropping and staggering of more diverse yields as well as using more drought tolerant plants. Indigenous slash/mulch systems [from the New Guinean and Latin American Tropics] may provide important lessons for improving the sustainability and productivity of agro-ecosystems in tropical countries (Thurston 1997). For swidden farmers it is possible to create a transition economy for them which does not involve burning the land; this agroforestry technique called Talun, is demonstrated in a few places and is important as a means of social integration as well as for land management where forest is diminishing.

Large amounts of cleared forest are wastefully left unlogged even though they contain potentially valuable export timber and woodchip material. Unextracted, felled timber is too great a potentially combustible fuel for fire in pre-wet season burn-offs. In response, the use of portable sawmills used under controlled environmental and silvicultural guidelines (Henderson, 1994) could allow timber cutters to log far more selectively and sensitively, maintaining forest bio-diversity and lowering potential fire fuel. Material not suitable for timber or woodchipping can be mulched and left on the soil to prevent soil erosion.

The areas being used for forestry and agriculture are in many cases not suitable; peat drying out becomes an inevitable source of fire, or soils are inadequate for production of cash crops. A new landuse plan for Indonesia could enable some of the potential fires to be prevented and greater bio-diversity preserved.

Lack of incentives for plantation managers to move towards sustainable land practices is of concern in achieving sustainability. As the issue is an international one, it is possible to involve international and local consumers in the process of changing practices of production. An 'eco-labelling' approach could establish a set of sustainability criteria for plantations; if plantations meet these they can label their products with an 'eco-label'. The process could be managed by the Indonesian Government with the assistance of local and international consumer organisations.

When very dry conditions occur and burning is banned, it may be necessary to increase enforcement. Moreover, increased enforcement of logging and burning restrictions from independent agencies may also be required, using international assistance from satellite photography to monitor compliance. Forest management is highly centralised in Indonesia and needs to be more sensitised to local responsibility for forest resources. An Institute for Forest Fire Management could be established from a plantation levy to research the issue further.

Physical

Difficulty controlling the extent of fires due to the extreme range over large land areas and lack of forward knowledge in fire detection, indicates a more sophisticated resource input is required. The need for better intelligence to detect fires from aerial observation and satellite imaging is also a necessity in monitoring compliance for clearing and burning restrictions over very large areas. Volunteer fire fighting groups could be established as in rural areas of Australia.

Biological

Lack of biodiversity from previously cleared forest which was overcut and under-planted, has resulted in excessive overgrowth of the highly flammable Imperata cyclindrica or Alang-alang grass, and more flammable secondary types of regrowth. This increases potential fuel over successive dry seasons. Greater replanting of more diverse species could help to restore forest to previous moisture levels.

More fire breaks are necessary between forested and planted land. From the vast plethora of literature on alley cropping, there is great potential for the successful integration of scientifically tested techniques into the rubber and palm oil plantation industry in Indonesia. The literature has also shown that diversity of productive plant species in agro-ecosystems is the key to sustainable production. Hence there is an imperative for adoption of intercropping to further diversify production and yields.

Climatic

The El Niño Southern Oscillation (ENSO) resulted in a very delayed, mild wet season in maritime Southeast Asia, arriving in late November instead of September. The ENSO was also thought to have influenced the existence of an inversion layer and very low wind speeds. Despite some warnings, the models for tropical regions are inadequate and unreliable. There are also considerable variations in local climates in Indonesia which are not well documented, monitored or modelled. This resulted in perfect conditions for the continuance of smoke haze. Greater computer modelling and studies for prediction of oncoming ENSOs and their effects would enable ASEAN governments to make contingency plans in an extended dry season. Finally, Greenhouse gas abatement must accelerate to minimise climate change, as this has been linked to El Niño. The lack of commitment to this process in developing nations will not last for long as these are the places which will suffer most. The Asian region has at least seen a glimpse of the possible future and it should act as a motivation to try to avoid it.


1997 Forest Fire and Haze Disaster in Southeast Asia

Box 1: Summarises the issues and some solutions.

Causative Factors

Potential Solutions

Socio-economic

Lack of education of people and officials results in mis-informed views of the true nature and extent of fire and associated smoke haze problems.

Improved education about the issues combined with a freer media coverage would result in increased awareness and more accurate information to facilitate positive local action. General environmental education is also needed.

Burning off was the most economically efficient means of land clearing to concurrently expand plantation production and maintain shifting cultivation.

Alternatives to this need to be examined, including ways of making existing plantation and shifting cultivated land more sustainably productive. Consider

  • intercropping,
  • staggering crop rotations,
  • use of drought tolerant plants and
  • slash and mulch agro-ecosystem techniques.

Swidden cultivation burn-offs become uncontrollable during extended dry seasons.

As forest is diminishing it is necessary to find a transition lifestyle for agriculturalists. The Talun approach could significantly reduce forest loss and assist social integration.

Lack of incentive for plantation managers to move towards more sustainable practices.

Governments can introduce an 'eco-label' approach to plantations whereby a set of sustainability criteria are to applied. If plantations meet these criteria they can label their product with a 'green-seal'.

Performance bonds can also be used to ensure sustainable practices are used.

Centralised forest management system requires review.

Centralised power can be sensitised to the local responsibility for forest resources.

An Institute of Forest Fire Management, could be established from a levy on plantations.

Poor land use decisions as some soils are not suitable for conventional tropical agriculture.

New land use plan is needed.

Physical

Difficulty controlling extent of fires due to extreme range over wide areas.

Need for better intelligence to detect fires and monitor compliance from aerial observation and satellite imaging.

Biological

Lack of biodiversity from previously cleared forest which was overcut and under-planted, resulted in excessive overgrowth of the highly flammable Imperata cyclindrica or Alang-alang grass, and more flammable secondary types of regrowth. This increases potential fuel over successive dry seasons.

Greater replanting of more diverse species to restore forest to previous moisture levels. More firebreaks between forested land. More research on bio-diversity.

Climatic

The El Niño Southern Oscillation (ENSO) resulted in a very delayed, mild wet season in maritime Southeast Asia, arriving in late November instead of September.

Inversion layer and low wind speeds resulted in ideal conditions for continuance of wide spread smoke haze.

Greater computer modelling for potential prediction of oncoming ENSOs. More monitoring stations to cover the mosaic of different climates in Southeast Asian region. ASEAN Governments could make contingency plans for drought and fire. Greenhouse Gas abatement must accelerate to limit [El Niño linked] climate change.

Forestry and the ESD Policy Process

Objectives of Ecologically Sustainable Development for Sustainable Forest Resource Use and Management
(Source: Commonwealth (1992). National Strategy for ESD)

Challenge:

To ensure Australia continues to refine and improve mechanisms for the ecologically sustainable management and use of its forests, by bringing together the commercial and non-commercial values of forests in such a way as to improve the material and non-material welfare of all Australians, and to ensure all forest values can be utilised on a sustainable basis.

Objective 1:

To manage and utilise Australia's forest estate for all forest values on an ecologically sustainable basis.

Objective 2:

To maintain ecological processes within the forests, maintain biodiversity, and optimise benefits to the community from all uses, within ecological constraints.

Objective 3:

To enhance the quality of life for successive generations of Australians by protecting and enhancing all of the values available from Australia's forests, and development of an ecologically sustainable and internationally competitive forest products industry.
