TLDR
In this paper, a comprehensive fire risk assessment system is proposed, which makes extensive use of geographic information technology to evaluate risk conditions, including human factors, lightning probability and fuel moisture content of both dead and live fuels.Abstract:
Fire risk assessment should take into account the most relevant components associated to fire occurrence. To estimate when and where the fire will produce undesired effects, we need to model both (a) fire ignition and propagation potential and (b) fire vulnerability. Following these ideas, a comprehensive fire risk assessment system is proposed in this paper,whichmakesextensiveuseofgeographicinformationtechnologiestoofferaspatiallyexplicitevaluationoffirerisk conditions. The paper first describes the conceptual model, then the methods to generate the different input variables, the approachestomergethosevariablesintosyntheticriskindicesandfinallythevalidationoftheoutputs.Themodelhasbeen applied at a national level for the whole Spanish Iberian territory at 1-km 2 spatial resolution. Fire danger included human factors, lightning probability, fuel moisture content of both dead and live fuels and propagation potential. Fire vulnerability was assessed by analysing values-at-risk and landscape resilience. Each input variable included a particular accuracy assessment, whereas the synthetic indices were validated using the most recent fire statistics available. Significant relations (P,0.001) with fire occurrence were found for the main synthetic danger indices, particularly for those associated to fuel moisture content conditions.read more

An insight into machine-learning algorithms to model human-caused wildfire occurrence
Marcos Rodrigues,Juan de la Riva +1 more
TL;DR: This paper proposes the use of ML within the context of fire risk prediction, and more specifically, in the evaluation of human-induced wildfires in Spain, and suggests that any of these ML algorithms leads to an improvement in the accuracy of the model when compared to traditional methods.

Generation and analysis of a new global burned area product based on MODIS 250 m reflectance bands and thermal anomalies
Emilio Chuvieco,Joshua Lizundia-Loiola,M.L. Pettinari,Rubén Ramo,Marc Padilla,Kevin Tansey,Florent Mouillot,Pierre Laurent,Thomas Storm,Angelika Heil,S. Plummer +10 more
TL;DR: In this article, the authors presented a new global burned area (BA) product, generated from the Moderate Resolution Imaging Spectroradiometer (MODIS) red (R) and near-infrared (NIR) reflectances and thermal anomaly data, thus providing the highest spatial resolution (approx. 250m) among the existing global BA datasets.

Geographically Weighted Regression: The Analysis of Spatially Varying Relationships
TL;DR: In this paper, the basic GWR model is extended to include local statistics and local models for spatial data, and a software for Geographically Weighting Regression is described. But this software is not suitable for the analysis of large scale data.

TL;DR: What is known and what is needed to develop a holistic understanding of the role of fire in the Earth system are reviewed, particularly in view of the pervasive impact of fires and the likelihood that they will become increasingly difficult to control as climate changes.
