2.1 Descrição curta da tecnologia

Definição da tecnologia:

Use of prescribed fire (or ‘controlled burn’) to reduce the fuel load in the form of live and dead plant material and thus to prevent the likelihood of more damaging wildfire.

2.2 Descrição detalhada da tecnologia

Descrição:

This technique is an essential management tool that applies fire to control the quantity of forest or scrubland fuels. The type of fire depends on the specific goals and on the weather conditions. Firstly, it is important to consider slope angle and the kind of fuels to be burned. Weather conditions include temperature, wind direction and air humidity. Another important aspect is the ability to control the speed of flame spread. In order to carry out the controlled fire, a plan has to be drawn up and approved and a fully-trained, authorised technician must be present in addition to the appropriate support teams (fire fighters, forest management teams). These teams use water or other means of combating the fire in the event of it possibly getting out of control and are in charge of the burning process.

Purpose of the Technology: The main purposes are enhancement of grazing areas and the creation of the so-called primary network for wildfire defence, which is a national network to limit the spread of wildfire. It involves strategically burning key sites (e.g. mountain ridges) to restrict the spread of the wildfire.

Establishment / maintenance activities and inputs: An analysis of weather conditions is made prior to carry out the prescribed fire. On the day of the prescribed fire itself, safety checks are made and the specific tasks of all the team members are defined. Wind direction and strength need to be minimal and are strictly controlled during burning. The size of the team depends on the specific problems of the area to be treated. Team size needed for about 10 ha is around 10 persons. The team members start along a line working from the top on the mountain along the contour and move downwards. Gentle breeze should be against the direction of the spreading of the fire. Workers use a drip-feed fuel can. There is also a strategy for prescribed fires by burning a strip along ridges of the mountains to avoid spreading of accidental wildfires and to burn in catchments the lowest point from which fire can spread to different areas and spread in different directions on the slopes.

Natural / human environment: Improved grazing management might also reduce the fuel load. Abandoning grazing in the forest can increase the fuel load and aggravate the occurrence and impact of wildfires. The creation or maintenance of grazing areas is determined by the size of the herd. Prescribed fire used as a means of improving grazing enables the local population needs to be addressed while considering environmental concerns. The prescribed fire also helps to protect the local population and their property by reducing the likelihood of devastating wildfire.

3.2 Tipo(s) atualizado(s) de uso da terra onde a tecnologia foi aplicada

Comentários:

Major land use problems (compiler’s opinion): The problem is linked to the loss of traditional natural pasture use. Since there is nowadays no grazing/pasture use of forests, the fuel load remains uncontrolled. It is also linked to minimising wildfire impacts and the creation of grazing land. As more people visit forest areas for leisure and accidentally set fire. Another problem is vandalism and arson.

4.1 Desenho técnico da tecnologia

4.2 Especificações técnicas/ explicações do desenho técnico

Prescribed fire is a practice used to manage vegetation in wildfire-prone areas. It consists of slowly burning strategic areas in the wet season, under specific weather and ground conditions and procedures: the soil should be moist, burning typically carried out in thin strips (normally 10m distance between two fire lines) from the top to the bottom of the slope, there should be only a gentle breeze blowing upslope and the ignition points should be 2m apart along the contour. The fire is allowed to progress downslope against the wind, which therefore provides some control. Burning is achieved by a number of the team who are prepared to dowse the flames if the fire gets out of hand. This degree of control is only possible when burning small areas with the same slope angle.

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do/a compilador/a ou de outra pessoa capacitada
The vegetation is adapted to the fire – impact minimization. How can they be sustained / enhanced? ore use of controlled fires.
With prescribed burning, larger areas can be treated compared to other fire control techniques, limited to strips in strategic areas, which are so difficult and expensive, whereas with prescribed burning, there is effective control of the vegetation over a large area”. How can they be sustained / enhanced? continue the use of controlled burning.
Difficult operating conditions and high costs make the technology unsuitable for certain areas costs How can they be sustained / enhanced? continued use of the controlled fire technique instead of other techniques.
It is cheaper than other control measures, for instance mechanical ones
In comparison with other techniques that manage biomass, this technique is more conservational, and it is culturally embedded in the local population way of life. It contributes to landscape diversification and the development of the local economy. It introduces fire as an essential feature of the Mediterranean landscape in a controlled manner.

6.8 Pontos fracos, desvantagens/riscos da tecnologia e formas de superá-los

Pontos fracos/vantagens/riscos na visão do/a compilador/a ou de outra pessoa capacitada	Como eles podem ser superados?
Air pollution	ensure that the wind direction does not carry smoke over settlements. However, it is not possible to eliminate the smoke problem. In particular, a certain degree of moisture is required in the fuel load to enable the fire to be controlled, in order that the burning temperature is low and this tends to produce smoke.
Lack of knowledge of people living near the burnt areas	improved education via schools, community meetings and in pamphlets.
Possibility of the control loss of the prescribed fire	care needed to prevent this happening.
Safety of the personnel carrying out the burn	conduct risk assessment exercises, carry out detailed planning and only apply the technology under the right weather conditions
