Paper: Reference Data Accuracy Impacts Burned Area Product Validation: The Role of the Expert Analyst

Received: 4 August 2022 / Accepted: 31 August 2022 / Published: 2 September 2022 Accurate reference data to validate burned area (BA) products are crucial to obtainingreliable accuracy metrics for such products. However, the accuracy of reference data can be affectedby numerous factors; hence, we can expect some degree of deviation with respect to real groundconditions. Since reference data are usually produced by semi-automatic methods, where human-based image interpretation is an important part of the process, in this study, we analyze the impact ofthe interpreter on the accuracy of the reference data. Here, we compare the accuracy metrics of theFireCCI51 BA product obtained from reference datasets that were produced by different analysts over60 sites located in tropical regions of South America. Additionally, fire severity, tree cover percentage,and canopy height were selected as explanatory sources of discrepancies between interpreters’reference BA classifications. We found significant differences between the FireCCI51 accuracy metricsobtained with [...]

Congress: 9th ICCFR – Characterization of Ecological Vulnerability to Wildfires based on the Fire patterns on a global scale

11 to 18 Nov, 2022 Fire is a natural phenomenon that has played a critical role in transforming the environment and maintaining biodiversity at a global scale. However, the plants in some habitats have not developed strategies for recovery from fire or have not adapted to the changes taking place in their fire regimes. Maps showing ecological vulnerability to fires could contribute to environmental management policies in the face of global change scenarios. The main objective of this work is to characterize the ecological vulnerability to fires based on how fires occur on a global scale. For this purpose, we are going to create zonal statistics by biome and by vulnerability category, finding out the average data of the different fire variables. For this, we have taken two spatial databases previously developed by us, Ecological Vulnerability to Wildfires and Wildfires Characteristics. Ecological Vulnerability to Wildfires is a global database that [...]

Congress: World Biodiversity Forum – ASSESSMENT OF BIODIVERSITY AND FIRE REGIMES RELATIONSHIP ON A GLOBAL SCALE

June 26 - July 1, 2022 Fire is a natural phenomenon that has played a critical role in transforming the environment and maintaining biodiversity at a global scale. However, nowadays some species could have difficulties to recovery from fires from different fire regimes. Maps showing spatial species distribution and it study under fire regimes could contribute to envionmental management in the face of global change. The main objective of this work is to study the relationship between species distribution and fire regime at global scale. To the this end, we created a spatial species distribution map based on 1,086 species of forest birds from GBIF database, climate, social, topography, environmental and soil factors using maximum-entropy approach. On the other hand, applying an unsupervised K-means clustering approach for fire regimes were identified and mapped globally. Fire regime is explained in terms of seasonality, patches, size and variability of burned areas, a [...]

Work: Analysis of the importance of the main drivers in the occurrence of fires for three fire regimes (2000 – 2020)

August, 2022 The influence of anthropic activity on the fire regime has been increasing in recent decades, highlighting the incidence of the socioeconomic and cultural context of the area. The fires in Bolivia are related to changes in the NDVI. The deforestation experienced in its forests is evident in the NDVI. This is also the most crucial factor in the occurrence of fires in Canada, being associated with the existence of monospecific forests, species that generally have a pyrophilic character. Also essential in Canada is the distance factor from human settlements. In Galicia, on the contrary, the most influential factor in the occurrence of fires is tree cover. Galicia is the largest national producer of pine and eucalyptus wood. The repopulation of these species in homogeneous and continuous masses of fuel favours the occurrence and spread of fires. The topographical conditions of Galicia have also been decisive since the accessibility [...]

Work: LEGISLACIÓN SOBRE INCENDIOS FORESTALES. SU INFLUENCIA EN LA OCURRENCIA DE INCENDIOS

21st Feb. 2022 Galicia is the autonomous region with the highest occurrence of wildfires, causing high economic, material, environmental, and, sometimes, personal losses year after year. The tools and measures for its prevention and control are established by the applicable legislation, whose powers are distributed between the State and the region. This dissertation studies whether said regulations in Galicia have a reactive character, that is, if their approval is immediate in years with a great wildfires activity or, on the other side, if it is of a preventive nature. To accomplish this, on the one hand, the rules and regulatory instruments in this matter have been analyzed, and forest fire data between the years 1968 and 2020 have been studied on the other. To help with the interpretation of the findings, these have been related by means of a timeline and a graph through which it has been possible to [...]

Congress: Third International Conference on Fire Behaviour and Risk

3–6 May 2022 Fire regimes can be defined by the extent of the burned area, size and intensity of fires, fire seasonal length, time of burning and/or annual variability. All these properties are not only controlled by the climate, as humans also play a crucial role in the distribution and characteristics of fires at the regional and global scale. The AnthropoFire project aims to identify the main human drivers of fire occurrence, and assess how these drivers should be included into fire models and fire risk assessment systems. As part of this task, annual maps of burned area have been generated from time series of Landsat images covering the period 1984–2020 using Google Earth Engine (GEE) over three regions (Bolivia, Spain–Portugal, and Canada) characterized by different fire regimes. For each of these regions, several physical and socio-economic variables such as those related to climate (i.e., temperature, precipitation, drought), vegetation, land [...]

Paper: Characterizing Global Fire Regimes from Satellite- Derived Products

Received: 14 March 2022 / Revised: 22 April 2022 / Accepted: 24 April 2022 / Published: 29 April 2022 We identified four global fire regimes based on a k-means algorithm using five variables covering the spatial, temporal and magnitude dimensions of fires, derived from 19-year long satellite burned area and active fire products. Additionally, we assessed the relation of fire regimes to forest fuels distribution. The most extensive fire regime (35% of cells having fire activity) was characterized by a long fire season, medium size fire events, small burned area, high intensity and medium variability. The next most extensive fire regime (25.6%) presented a long fire season, large fire events and the highest mean burned area, yet it showed the lowest intensity and the least variability. The third group (22.07%) presented a short fire season, the lowest burned area, with medium-low intensity, the smallest fire patches and large variability. The [...]
