Forest Fire Risk

Forest fire hazard and risk mapping is an essential tool for planning and decision making regarding the prevention and suppression of forest fires,as well as fire management in general, as it allows the spatial visualization of areas with higher and lower ignition probability. This study aimed to develop a forest fire risk zoning map for the Vila Velha State Park and its surroundings (Ponta Grossa, Paraná State, Brazil), for the period of higher incidence of forest fires (from April to September) and for the period of lower incidence (from October to March). The following risk and hazard variables were identified: human presence, usage zones, topographical features, soil coverage and land use and meteorological conditions. Coefficients (0 to 5) reflecting the fire risk or hazard degree were allocated to each variable in order to construct the maps. The integration of these maps, through a weighting model, resulted in the final risk mapping. The very high and extreme risk classes represented about 38% of the area for both periods. The forest fire risk mapping spatially represented the levels of fire risk in the area, allowing the managers to identify the priority sectors for preventive actions in both fire seasons.

Forest Fire Risk

The number of forest fires ignitions has decreased worldwide, thus observing increased levels of intensity and destruction, endangering urban areas and causing material damages and deaths (Portugal, 2017). Forest fire hazard mapping supported by the surveillance strategy targeted at very susceptible areas with high losses potential are the common tools of fire prevention. Each municipality creates its own Forest Fire Hazard Map, and so it is observed that along the administrative boundaries, discrepancies occur, even when identical types of land use are in place. The evolution of geographic information systems technology sustained by the open-source satellite imagery, along with the innovative Habitat Risk Assessment model of the InVEST software, allowed the creation of an easily applicable trans-administrative boundary fire hazard map, with frequent update capabilities and fully open source. This work considered three municipalities (Tomar, Ourém, and Ferreira do Zêzere) that annually observe various forest fire occurrences. Results enabled the creation of a homogeneous Forest Fire Risk Map, using landuse, slope, road access network, fire ignitions’ history, visualization basins, and the Normalized Difference Vegetation Index (NDVI) as variables. All variables correlate with each other using different weights, in which the different classes of land use are considered as habitats and the remaining variables as fire hazard stressors. The results produce a coherent monthly updated Risk Map, which is an alternative to many risk assessment systems used worldwide.

Forest Fire Hazard

Forest fires constitute one of the greatest risks for certain ecosystems services. Hence, the location planning of firefighting units based on forest fire hazard is a key point for the immediate containment of fire incidents before they become uncontrollable. The primary aim of the paper is the estimation and finding of the required number and positions (i.e. the exact geographical locations and the respective type of installation – fire hydrant etc.) of fire fleet to fully cover (in terms of travel time) the districts of fire services in Chalkidiki (Greece), taking into account the scalable fire susceptibility. The proposed location plans revealed the fact that most of the regions may adequately respond to the fire vulnerability with the current forces, whereas a few regions clearly need a reinforcement in order to sufficiently cover their territories. A future perspective may be related with the exploration of best locations through the entire study area, merging the current administrative boundaries. One more asset of the project constitutes the flexibility and applicability of the sub-modules to other geographic regions after the necessary adjustments to local conditions.

Fire Ignition

Every year forest fires destroy millions of hectares of land worldwide. Detecting forest fire ignition in the early stages is fundamental to avoid forest fires catastrophes. In this approach, Wireless Sensor Network is explored to develop a monitoring system to send alert to authorities when a fire ignition is detected. The study of sensors allocation is essential in this type of monitoring system since its performance is directly related to the position of the sensors, which also defines the coverage region. In this paper, a mathematical model is proposed to solve the sensor allocation problem. This model considers the sensor coverage limitation, the distance, and the forest density interference in the sensor reach. A Genetic Algorithm is implemented to solve the optimisation model and minimise the forest fire hazard. The results obtained are promising since the algorithm could allocate the sensor avoiding overlaps and minimising the total fire hazard value for both regions considered.

Forest Fire Hazard

The authors have developed a probabilistic risk assessment method on a forest fire as one of external hazards. A hazard curve by heat effect of a forest fire had been obtained by using a logic tree in our previous study. The main application target of the forest fire probabilistic risk assessment is for sodium-cooled fast reactor systems. Databases for a hazard curve evaluation were based on forest fire records, meteorological and vegetation data of a studied area which is near a typical sodium-cooled fast reactor in Japan. There are two intensity parameters of heat effect of a forest fire, namely, reaction intensity and frontal fireline intensity. The hazard curves of these two intensities obtained in our previous study were referred to as “reference case” where constant breakout frequency throughout a day, equal probability distribution for potential breakout points, and firefighting effect on a forest fire were assumed as a priori. The reference reaction intensity and the fireline intensity became 935 kW/m2 and 107 kW/m for the annual exceedance frequency of 10−4/year, respectively. This paper describes a sensitivity study of the hazard curves on condition parameters where frequency/probability variables in the logic tree were varied within respective fluctuation ranges in order to evaluate quantitative effects on the frequency and/or intensity of the hazard curves. As for the forest fire breakout frequency and propagation probability, important variables are “fluctuation of breakout time”, “probability distribution fluctuation of breakout point”, and “firefighting effect on a probability of forest fire arrival at a nuclear power plant (NPP)”. The intensities increase in daytime due to sunshine, and the breakout probability in daytime is statistically 2.8 times higher than a daily average, and that in nighttime is 1/9 of the average. As a result, the hazard curves of the reaction intensity and the fireline intensity increased around 4% and 14% respectively in intensity direction in comparison with those of the reference case. The “fluctuation of breakout time” only affects the intensities of the hazard curves, but not the frequency. As for the “probability distribution fluctuation of breakout point”, one selected point is given higher probability than the other points. The hazard curves vary around +70% to −40% in frequency direction; each breakout point has different distance to the NPP and the forest fire arrival probability varies with a propagation duration. Namely, the longer duration, the higher probability of the extinguishment by firefighting, accordingly the lower probability of the arrival at the NPP. The “probability distribution fluctuation of breakout point” affects only the frequency of the hazard curves, but not the intensities. “Firefighting effect on a probability of forest fire arrival at an NPP” was conservatively assumed for the sensitivity study in which there is no firefighting action outside the NPP, hence all potential forest fires arrive at the NPP. The hazard curves remarkably increase around 40 to 80 times in frequency direction in comparison with those of the reference case. This is because most of forest fires in Japan are extinguished within one to two hours by fire departments, and the conditional probability of a forest fire arrival at an NPP from a potential breakout point with kilometer range distance was evaluated to be very low (i.e. less than a few percent). The “firefighting effect on a probability of forest fire arrival at an NPP” only affects the frequency of the hazard curves, but not the intensity. This study indicated that the most significant factor in the forest fire hazard curve is whether the firefighting action outside an NPP is expected before the arrival at an NPP.

Hierarchy Process

<p>Anthropogenic factors and climate change induced severe forest fires that are reoccurring globally. Because of the large spatial scale, frequent occurrence, and danger involved with the forest fires, remote sensing-based approaches are best suited to study this phenomenon. However, there are few studies addressing the temporal effects of the various factors associated with the  forest fire. In this work, by using Analytical Hierarchy Process (AHP), a multi-criteria decision support system and geostatistical methods namely Getis-Ord Gi* statstic and Mann Kendall trend test, we have developed a framework to understand the temporal dynamics of forest fire hazard and associated factors by demarcating the hotspots of forest fire using freely available datasets . The proposed framework has been applied on the Similipal Biosphere Reserve (SBR), Odisha, India. With an area of 5569 km<sup>2</sup>, the SBR is the sixth largest biosphere reserve in India, comprising of a national park, bird sancturary, tiger reserve, and elephant corridor. Due to its biodiversity and importance in terms of rich and endemic species of flora and fauna, SBR was brought into the umbrella of world network of biosphere reserve under the Man and Biosphere (MAB) programme of UNESCO in the year 2008. Although being a biosphere of international importance, the SBR annually experiences nearly 12 km<sup>2</sup> of fire damage.Through this work, the most significant clusters of forest fire hotspots have been demarcated. We have used factors related to topographical, climatic, and physical characteristics of forest to generate forest fire hazard index at annual scale for 28 years (1988 – 2018) using AHP method. The geostatistical methods were applied on the generated annual fire hazard index data to demarcate the zones of emerging hotspots of forest fire. The results indicate that temporally, the trend of forest fire hazard in buffer zone of the area (Similipal Sanctuary) is decreasing, whereas in core area (Similipal National Park), it is increasing and corelates with the temporal trend of vegetation density in the whole area. However, vegetation density and land surface temperature in the core area does not changes significantly with time. The emerging hotspot analysis shows that most of the region (32% of the total area) is exhibiting an oscillating behaviour with respect to the fire hazard over the studied time-period of 28 years, with more than 50% of the years showing increasing trends of fire hazard. A total of 186 km<sup>2 </sup>of the region is persistently a hotspot of fire hazard in studied time-period. Overall, 11% of the study area is either under persistent fire hazard or showing increasing trend of fire hazard. However, in the central part of the SNP, the fire hazard is decreasing with time. The same region also observes intense rain, and this could be a factor for the observed decrement in the fire hazard. The results can be used for mitigating the fire hazard of the SBR, alsothe proposed framework can be applied globally to any region with dense vegetation for fire hazard spatiotemporal assessments.</p>

The occurrence of forest fire in Jambi can be considered as an annual phenomenon. It happenes almost every year in every type of land uses, including industrial timber plantation area of PT Wirakarya Sakti. The drivers of fire are a combination between natural factors and an anthropogenic factor, which in this case is traditional land preparation activity conducted by local farmer. To maintain their source of livelihoods, farmers convert forest land into seasonal agricultural land (ladang) using ‘slash and burn’ method. This activity occures along with the changes in social economic condition. Currently, although this circumstance has existed for a long time, availability of information regarding forest fire-prone area especially in industrial timber plantation is really minutes. Based on this condition, this study aims to model and develop spatial information on the vulnerability forest fire in industrial timber plantation (HTI) area. The specific objectives are: 1) To identify biophysical factors that affect of forest fire, 2) To identify the significance of community activities and land tenure factors to forest fires event in the area, 3) To analyze communities motivations and actions in regards to forest fire events, and 4) To analyze synergy between actual land use with HTI Spatial Planning (RTR-HTI). The results of using logistic regression analysis showed that the most significance biophysical variable are soil type and rainfall, while on the anthropogenic variable are the distance from land and the distancefrom road. Pearson correlation analysis and regression analysis suggested that community motivations and actions are affected by social indicators. Based on these facts, spatial analysis using GIS was conducted. The result showed that the value of land use suitable (LUS) was 88.1% (218,289 ha) and not suitable was 11.9% (29,589 ha) from the land allocation of RTR-HTI. Using Analytic Hierarchy Process (AHP), the relative importance weight for each factor was derivied to be included in hazard model. The hazard map showed that fire hazard can be classified into high category (118,925 ha), moderate category (175,272ha) and low category (11,369 ha).
