Guidelines for the Prevention and Control of Forest and
Land Fires
INTRODUCTION
Forests and land are highly potential natural resources
that can be utilized for national development. However, forests and land often
face threats and disturbances that hinder conservation efforts. One of the
major threats is forest and land fires.
Forest and land fires have negative impacts on plants,
socio-economic conditions, and the environment. Thus, forest and land fires not
only damage the forests and land themselves but also disrupt overall
development processes.
For the time being, forest and land fires are still
considered natural disasters, similar to earthquakes and typhoons. However,
forest and land fires differ from these natural disasters. They can be
prevented or controlled because we already know that during the dry season or
in fire-prone areas, a lack of preventive measures will almost certainly lead
to fires. Based on this, the control of forest and land fires must be handled
in a planned, comprehensive, integrated, and sustainable manner. In other words,
fire control should not focus only on extinguishing fires during the dry season
but must also include preventive measures conducted continuously in both dry
and rainy seasons.
BASIC PRINCIPLES OF FOREST AND LAND FIRE
The factors causing forest and land fires are heat, fuel,
and air/oxygen. These three elements form the fire triangle. In principle,
forest and land fire control involves eliminating one or more of these
elements.
The spread of fire depends on fuel and weather. Heavy
fuels such as logs, stumps, and branches may burn slowly when dry but produce
high heat. Light fuels such as dry grass, ferns, pine needles, and litter
ignite easily and spread rapidly, potentially causing large forest/land fires.
Important weather elements in forest and land fires
include wind, humidity, and temperature. Strong winds increase oxygen supply,
accelerating fire spread. In large fires, wind becomes simultaneous; the larger
the fire, the stronger the wind due to the movement of dense air masses toward
the low-pressure heated area.
Fuel moisture content is also essential. Under normal
conditions, fires spread slowly at night because fuel absorbs moisture. Dry air
during the day can accelerate fires. Therefore, technically, controlling
forest/land fires is easier at night than during the day. However, this does
not mean serious fire control should not be performed during the day. In
reality, fires are mostly fought during the day due to various considerations.
Air temperature also affects firefighters; in hot conditions, endurance and working
capacity decrease.
IMPACTS OF FOREST AND LAND FIRES
Impacts on Bio-Physical Conditions
Forest and land fires cause extensive damage. Impacts
range from burn injuries on tree trunks to the complete destruction of
vegetation. The most concerning consequence is the loss of genetic resources
(germplasm) along with the destruction of vegetation. Fires also weaken stand
resistance to pests and diseases. Trees that suffer burns may not die
immediately but later succumb to decay or deterioration.
Forest fires reduce stand density, damage forage for
wildlife, and disturb habitats. The destruction of one generation of forest
stands means losing long-term investment and time required for forest
regeneration.
Forest and land fires damage soil physical properties by
destroying humus and organic matter. As a result, the soil becomes exposed to
heat and surface runoff, leading to erosion, reduced percolation, and declining
groundwater levels. Repeated fires deplete litter layers and kill
microorganisms essential for soil fertility.
Fires also damage soil surfaces and increase erosion.
Burned areas on slopes in upstream watershed regions reduce water storage
capacity downstream. Observations show that repeated fires degrade land
quality, causing erosion and flooding, which subsequently cause sedimentation
in waterways, rivers, lakes, and dams.
Impacts on Socio-Economic Conditions
Bio-physical changes to natural resources and the
environment reduce the carrying capacity and productivity of forests and land.
This leads to decreased community and national income from forestry,
agriculture, industry, trade, tourism services, and other sectors dependent on
natural resources.
Impacts on the Environment
Besides material loss, forest and land fires also cause
massive smoke accumulation. Fires in 1994 and 1997 drew global attention due to
a specific weather condition where smoke was trapped under a cold atmospheric
layer over Indonesia and neighboring countries, reducing visibility and
disrupting land, sea, and air transportation.
SOURCES OF FOREST AND LAND FIRE IGNITION
Forest and land fire incidents have increased over the
past decade in Indonesia. Most fires are caused by human negligence. Moreover,
fire problems have been exacerbated by extremely dry conditions associated with
periodic global climate changes affecting several regions in Indonesia.
Forest fires may occur unintentionally or intentionally.
Unintentional causes include negligence by smokers, tourists, adventurers,
forest workers, and forest product collectors. Many intentional fires originate
from land clearing by industrial plantation developers, estate developers,
forest encroachers, shifting cultivators, herders seeking to stimulate grass
growth, hunters, honey collectors, and others.
Agriculture
Most fires originate from burning practices in rural land
management systems. Forest clearing to create new agricultural areas has long
been practiced. After 2–3 years of cultivation, soils lose fertility and are
abandoned. New forest areas are then cleared for the same purpose, a cycle that
increases with population growth.
Burning is also conducted in settled agricultural lands
to remove crop residues and in plantation preparation areas. Since fires
usually occur in the dry season and lack adequate supervision, they easily
spread into adjacent forest/land areas.
Forest Plantation Development
In forest planting activities, especially through
clear-cutting or reforestation, fire is used to clear land for planting.
Carelessness often causes fires to spread into surrounding forest areas.
Logging
Fires caused by logging activities often stem from
negligence during the dry season. For example, sparks from chainsaw exhaust may
ignite dry materials and spread across the forest floor.
Coal Fire
Coal seam fires are a unique problem, such as those in
East Kalimantan. Coal layers ignited during severe fires in 1993 continue to
smolder underground. During the rainy season, the problem is minimal, but in
the dry season, reduced soil moisture causes cracks through which heat escapes,
igniting surrounding dry vegetation.
Many coal fire points remain and continue to pose
hazards.
Natural Events
Although rare, forest and land fires may also originate
from natural causes such as lightning. Since they occur during the rainy
season, impacts are usually minor—however, if lightning strikes flammable tree
canopies (e.g., pine), major crown fires may occur.
INTEGRATED FOREST FIRE MANAGEMENT
Forest fires occur almost every year and increasingly
damage the environment. The main cause of control failure is fragmented,
uncoordinated approaches. Most efforts focus on fire suppression while
neglecting prevention and fuel management. Therefore, an integrated and
coordinated fire management system is essential, consisting of:
- Prevention
of human-caused fires through education and outreach.
- Effective
fire detection through observation networks, efficient patrols, satellite
imagery and GIS, communication systems, etc.
- Rapid
initial response.
- Strong
and directed follow-up action.
Each component is crucial. Neglecting any component can
cause system failure.
Fire management plans for each area must define
objectives, high-risk zones (based on historical data or hazard analysis),
available resources, and planned activities. These plans should be reviewed
regularly.
FOREST AND LAND FIRE CONTROL
Prevention of Forest and Land Fires
Prevention is better than cure. With a good prevention
program, fires may not occur, minimizing suppression costs and avoiding damage.
Prevention includes reducing hazards and risks through education, proper
silviculture practices, fuel modification, and law enforcement.
Extension and Education
Since most fires in Indonesia are human-caused—whether
through negligence or intent—community support and cooperation are crucial.
Therefore, repeated outreach and education efforts are essential to raise
awareness and involvement in forest protection.
Key considerations include:
a. Many people remain unaware or misinformed about fire
prevention practices.
b. Carelessness by smokers, campers, and loggers
contributes significantly.
c. Intentional or anti-social actions such as vandalism
or selfish acts can trigger fires.
The first two groups (a & b) must be educated. Those
uninformed must receive correct information; careless individuals may be
targeted through publications or law enforcement where necessary. Cooperation
with these groups helps address the third group.
Education plans must include community leaders, local
media, audiovisual materials, circulars, leaflets, and pocket books.
Media such as newspapers, TV, and radio are effective
tools for reaching the public, especially during dry seasons.
Silvicultural Practices
In a forest area with mixed vegetation or an agricultural
crop of various ages, fire from a surface fire may spread from shrubs or
understory plants upward into the canopy. Dead trees leaning on other trees
also facilitate the spread of fire from a surface fire into a crown fire.
Silvicultural treatments must be carefully planned to prevent the accumulation
of fuel loads. Pruning and thinning should not be conducted during the dry
season if the pruned branches and logging debris are left on-site, as these materials
can easily ignite. Slash from thinning operations should be removed promptly.
The proper planning of timber harvesting activities,
particularly road construction, is essential to ensure that fire does not
spread uncontrollably during dry conditions. The establishment of firebreak
systems and the removal of slash piles are important measures to reduce fire
risk.
Fuel Modification
Fuel modification includes the reduction of combustible
materials through methods such as:
- Mechanical
removal
- Burning
under controlled conditions
- Grazing
- Utilizing
materials for local needs (e.g., firewood)
Fuel modification primarily aims to:
- Reduce
the amount of fuel that can sustain a fire.
- Break
the continuity of fuel horizontally and vertically.
- Make
the area more resistant to fire spread.
One of the most important fuel treatments is prescribed
burning, which is the intentional use of fire under controlled conditions
to reduce fuel loads. Prescribed burning must be carried out by trained
personnel and according to regulations, with careful consideration of weather
conditions, fuel conditions, and topography.
Law Enforcement
Law enforcement is a crucial component of fire
prevention. Regulations related to the use of fire in forest and land
management must be enforced consistently. Effective law enforcement includes:
- Clear
regulations
- Strong
institutional support
- Firm
action against violators
- Public
awareness that fire use without proper control is illegal
The purpose of law enforcement is not merely to punish
but also to deter people from committing actions that lead to fires.
DETECTION AND REPORTING
Detection plays a vital role in every forest fire
management activity. Fast and accurate fire detection, followed by efficient
communication and immediate action, is essential for successful fire
suppression. Detection requires careful consideration of factors such as:
- The
size of the area to be monitored
- The
level of fire risk
- Topography
- Vegetation
type
- Available
personnel
Forest fire detection involves:
- Observation
Networks
Includes the construction of lookout towers, use of
vantage points, and deployment of observers.
- Patrols
Both ground and aerial patrols may be conducted depending
on the situation.
- Remote
Sensing
Utilization of satellite imagery (such as NOAA, MODIS, or
other sensors) and GIS to detect hotspots and fire spread.
- Community
Reports
Local communities often detect fires earlier than
authorities and therefore serve as an important source of information.
An effective communication system (radio, telephone,
mobile networks) must be in place for quick reporting.
INITIAL ATTACK
Initial attack refers to immediate suppression efforts
conducted as soon as a fire is detected. It is the most critical phase because
the highest chance of successful control occurs within the first minutes or
hours after ignition.
Factors influencing initial attack success include:
- Early
detection
- Availability
of trained personnel
- Accessibility
to the fire site
- Weather
conditions
- Equipment
readiness
Initial attack teams must be trained to recognize fire
behavior, choose the best suppression strategy, and ensure safety procedures
are followed.
FOLLOW-UP ACTIONS
If the initial attack fails, follow-up actions (extended
attack) are required. These include:
- Reinforcement
of personnel and equipment
- Construction
of containment lines
- Use
of heavy machinery
- Possible
aerial firefighting techniques
- Long-term
mop-up operations to prevent re-ignition
Coordination between agencies becomes essential during
extended operations.
SUPPRESSION TECHNIQUES
Forest and land fire suppression includes various
techniques:
- Direct
Attack
Firefighters work directly on the fire edge using tools
and water.
- Indirect
Attack
Firelines are constructed at a distance from the fire,
and controlled burning may be conducted to stop fire spread.
- Aerial
Support
Includes water bombing, surveillance flights, and
personnel transport.
- Mop-Up
Operations
Ensuring all embers, hotspots, and leftover fuels are
fully extinguished to prevent re-ignition.
ORGANIZATION AND PERSONNEL
Forest fire management must involve a clear
organizational structure:
- Command
and control system
- Trained
firefighting units
- Support
teams (logistics, communication, medical)
- Coordination
between government, private sector, communities, NGOs, and military/police
Training should include:
- Fire
behavior
- Suppression
techniques
- Equipment
handling
- Field
safety
- First
aid
EQUIPMENT
Firefighting equipment may include:
- Basic
tools (hoes, machetes, rakes)
- Portable
pumps and hoses
- Water
tanks
- Protective
gear
- Vehicles
(trucks, 4WD, motorcycles)
- Communication
equipment
Maintenance and readiness checks must be conducted
routinely.
COMMUNITY PARTICIPATION
Community involvement is one of the most important
aspects of forest and land fire management. Forms of participation include:
- Establishing
community fire brigades
- Participating
in awareness programs
- Reporting
fires early
- Helping
build firebreaks
- Supporting
law enforcement
Communities living near forests are typically the first
to detect fires and therefore play a crucial role in prevention, detection, and
suppression.
COORDINATION AND COOPERATION
Integrated forest and land fire management must involve
cooperation among:
- Government
agencies
- Private
companies
- Local
communities
- NGOs
- Universities
- International
partners
Coordinated efforts help ensure the optimal use of
resources and prevent overlapping actions.
REHABILITATION OF BURNT AREAS
Fire-damaged areas must be rehabilitated to prevent
further environmental degradation. Rehabilitation activities include:
- Soil
stabilization
- Erosion
control
- Reforestation
- Restoration
of habitats
- Community
involvement in restoration
The objective is to restore ecosystem functions and
prevent future fire risks.
CONCLUSION
Forest and land fires are not natural disasters that
occur randomly—they are largely preventable. With proper planning, consistent
prevention efforts, effective detection systems, and coordinated suppression
strategies, fires can be minimized. Forest and land fire management must be:
- Planned
- Integrated
- Comprehensive
- Sustainable
Only through collective action can we protect forests and
support sustainable development.
