Negligent and intentional fires in Portugal: spatial distribution characterization

Science of The Total Environment, Vol. 624 (May 2018), pp. 424-437,


[Highlights] [::] Average fire size is much higher for intentional than for negligent fires. [::] Incidence of negligent and intentional fires has different distribution patterns. [::] Higher drivers' influence for intentional fires, burnt area and in the south region. [::] Human's drivers and altitude are the most important for fire ignitions. [::] Negligent (intentional) fires burn more forest and agricultural (human) areas. [Abstract] In the European context, Portugal is the country with the highest number of wildfires and the second with more burnt area. The vast majority of ...

Land cover mapping from remotely sensed and auxiliary data for harmonized official statistics

ISPRS International Journal of Geo-Information, Vol. 7, No. 4. (21 April 2018), 157,


This paper describes a general framework alternative to the traditional surveys that are commonly performed to estimate, for statistical purposes, the areal extent of predefined land cover classes across Europe. The framework has been funded by Eurostat and relies on annual land cover mapping and updating from remotely sensed and national GIS-based data followed by area estimation. Map production follows a series of steps, namely data collection, change detection, supervised image classification, rule-based image classification, and map updating/generalization. Land cover area ...


Portugal wildfire management in a new era assessing fire risks, resources and reforms

(February 2018)


[Executive summary] Portugal has one of the highest forest fire risk rankings in Europe. Fire researchers all point to the same combination of contributing factors: shifting demographics with population moving from rural to urban areas, changes in land use with more agricultural and forested areas left unattended and not being maintained, and fragmentation of land ownership patterns that discourage investment in forest management and fire planning. The trend of annual burned area for the last four decades confirms a new level in fire activity in Portugal, despite ...

Assessment and validation of wildfire susceptibility and hazard in Portugal

Natural Hazards and Earth System Science, Vol. 10, No. 3. (16 March 2010), pp. 485-497,


A comprehensive methodology to assess forest fire susceptibility, that uses variables of strong spatial correlation, is presented and applied for the Portuguese mainland. Our study is based on a thirty-year chronological series of burnt areas. The first twenty years (1975–1994) are used for statistical modelling, and the last ten (1995–2004) are used for the independent validation of results. The wildfire affected areas are crossed with a set of independent layers that are assumed to be relevant wildfire conditioning factors: elevation, slope, ...


Spreading like wildfire

Nature Climate Change, Vol. 7, No. 11. (November 2017), pp. 755-755,


The 2017 wildfire season has seen unusually high fire levels in many parts of the world, with extensive and severe fires occurring in Chile, the Mediterranean, Russia, the US, Canada and even Greenland. Is this a sign of things to come? [Excerpt] During January and February, Chile experienced what their president Michelle Bachelet called “The greatest forest disaster in our history”. The nation was not adequately equipped to tackle these fires, leading the government to enact a state of emergency and accept ...


Spatial distribution of citizen science casuistic observations for different taxonomic groups

Scientific Reports, Vol. 7, No. 1. (16 October 2017),


Opportunistic citizen science databases are becoming an important way of gathering information on species distributions. These data are temporally and spatially dispersed and could have limitations regarding biases in the distribution of the observations in space and/or time. In this work, we test the influence of landscape variables in the distribution of citizen science observations for eight taxonomic groups. We use data collected through a Portuguese citizen science database ( We use a zero-inflated negative binomial regression to model the distribution ...


Sun in parts of UK and France blocked out the smoke from wildfires in Spain and Portugal

Severe Weather Europe, Vol. 2017 (2017), 111799


[Excerpt] [...] Parts of Spain and Portugal are experiencing extreme fires, caused by a combination of a dry spring and summer and likely arson. The thick smoke was advected by southerly winds into the Bay of Biscay, northwestern France (Brittany) and across the United Kingdom. Residents of this area awoke to a dark orange and brown sky, with the Sun either completely blocked or strongly subdued. While smoke from fires being blown large distances is not rare, it is rare for ...

On the key role of droughts in the dynamics of summer fires in Mediterranean Europe

Scientific Reports, Vol. 7, No. 1. (6 March 2017), 81,


Summer fires frequently rage across Mediterranean Europe, often intensified by high temperatures and droughts. According to the state-of-the-art regional fire risk projections, in forthcoming decades climate effects are expected to become stronger and possibly overcome fire prevention efforts. However, significant uncertainties exist and the direct effect of climate change in regulating fuel moisture (e.g. warmer conditions increasing fuel dryness) could be counterbalanced by the indirect effects on fuel structure (e.g. warmer conditions limiting fuel amount), affecting the transition between climate-driven and ...


Forest fires in a changing climate and their impacts on air quality

Atmospheric Environment, Vol. 45, No. 31. (October 2011), pp. 5545-5553,


[Abstract] In a future climate scenario forest fire activity over Portugal will substantially increase and consequently area burned and forest fire emissions to the atmosphere are also expected to increase. This study investigated the impact of future forest fire emissions on air quality over Portugal under the IPCC SRES A2 scenario. Reference and future climate change scenarios were simulated using the MM5/CHIMERE air quality modelling system, which was applied over Europe and over Portugal, using nesting capabilities. The initial and boundary ...


Characteristics and controls of extremely large wildfires in the western Mediterranean Basin

Journal of Geophysical Research: Biogeosciences, Vol. 121, No. 8. (August 2016), pp. 2141-2157,


Large fires account for a disproportionally high percentage of area burned with potentially severe environmental and socioeconomic impacts. This study characterizes extremely large fires (ELFs; 2500–24,843 ha) in Portugal (1998–2013) and the concomitant fuel and weather conditions, analyzing the response of ELF size to their variation. ELF burned less shrubland-grassland (33% of the total ELF area) than forest (59% of total), the latter primarily composed by pine and pine-eucalypt. High fuel hazard was the norm, as indicated by median values of 0.98 ...


Atmospheric conditions associated with the exceptional fire season of 2003 in Portugal

International Journal of Climatology, Vol. 26, No. 13. (15 November 2006), pp. 1741-1757,


The summer of 2003 was characterised by exceptional warm weather in Europe, particularly during the first two weeks of August, when a devastating sequence of large fires was observed, reaching an amount of circa 450 000 ha, the largest figure ever recorded in Portugal in modern times. They were concentrated in two relatively confined regions of Portugal and a considerable proportion of burnt area was due to fires started on the 2nd and 3rd of August. [\n] It is shown that the ...

International Journal of Wildland Fire, Vol. 10, No. 2. (2001), pp. 223-240,


Field measurements of moisture content of several fine fuels (shrub vegetation and live foliage) were performed in Central Portugal and in Catalunya (NE Spain) for 1–10 years. Seasonal and interannual variation of live fine fuels of several species in two regions of the Iberian Peninsula are analysed. The species were grouped in three sets according to their relatively high, intermediate or low seasonal variability. Meteorological data from nearby stations were collected in each study area and used in the evaluation of ...


Decreasing fires in Mediterranean Europe

PLoS ONE, Vol. 11, No. 3. (16 March 2016), e0150663,


Forest fires are a serious environmental hazard in southern Europe. Quantitative assessment of recent trends in fire statistics is important for assessing the possible shifts induced by climate and other environmental/socioeconomic changes in this area. Here we analyse recent fire trends in Portugal, Spain, southern France, Italy and Greece, building on a homogenized fire database integrating official fire statistics provided by several national/EU agencies. During the period 1985-2011, the total annual burned area (BA) displayed a general decreasing trend, with the ...


Combining forest structure data and fuel modelling to classify fire hazard in Portugal

Annals of Forest Science, Vol. 66, No. 4. (2009), pp. 415-415,


Fire management activities can greatly benefit from the description of wildland fuel to assess fire hazard. [\n] A forest typology developed from the Portuguese National Forest Inventory that combines cover type (the dominant overstorey species) and forest structure defined as a combination of generic stand density (closed or open) and height (low or tall) is translated into fuel models. Fire behaviour simulations that accounted for the fire environment modification induced by stand structure resulted in an objective and quantitative assessment of fire ...


Fire activity in Portugal and its relationship to weather and the Canadian Fire Weather Index System

International Journal of Wildland Fire, Vol. 17, No. 3. (2008), 328,


The relationships among the weather, the Canadian Fire Weather Index (FWI) System components, the monthly area burned, and the number of fire occurrences from 1980 to 2004 were investigated in 11 Portuguese districts that represent respectively 66% and 61% of the total area burned and number of fires in Portugal. A statistical approach was used to estimate the monthly area burned and the monthly number of fires per district, using meteorological variables and FWI System components as predictors. The approach succeeded ...

Post-fire survival and regeneration of Eucalyptus globulus in forest plantations in Portugal

Forest Ecology and Management, Vol. 310 (December 2013), pp. 194-203,


We modelled post-fire mortality and regeneration of E. globulus in forest plantations. Mortality was low but most trees were top-killed showing basal regeneration only. Mortality and top-kill were mainly affected by fire severity and tree diameter. Stand composition and vegetation cover also affected the probability of top-kill. Basal resprouting was affected by fire severity, tree diameter and topography. Eucalyptus globulus is one of the most important pulpwood plantation species in the world, and nowadays it is present in most continents. ...

A stochastic approach to optimize Maritime pine (Pinus pinaster Ait.) stand management scheduling under fire risk. An application in Portugal

Annals of Operations Research In Annals of Operations Research (26 January 2011), pp. 1-19,


The paper discusses research aiming at the development of a management scheduling model for even-aged stands that may take into consideration fuel treatments to address the risk of wildfires. A Stochastic dynamic programming (SDP) approach is proposed to determine the policy (e.g. the fuel treatment and thinning schedules and the rotation age) that produces the maximum expected discounted net revenue. Fuel treatment activities encompass shrub cleanings. Emphasis was on combining a deterministic stand-level growth and yield model with wildfire occurrence and ...


Assessment of forest biomass for use as energy. GIS-based analysis of geographical availability and locations of wood-fired power plants in Portugal

Applied Energy, Vol. 87, No. 8. (01 August 2010), pp. 2551-2560,


Following the European Union strategy concerning renewable energy (RE), Portugal established in their national policy programmes that the production of electrical energy from RE should reach 45% of the total supply by 2010. Since Portugal has large forest biomass resources, a significant part of this energy will be obtained from this source. In addition to the two existing electric power plants, with 22 MW of power capacity, 13 new power plants having a total of 86.4 MW capacity are in construction. Together these ...


A new procedure to estimate the RUSLE EI30 index, based on monthly rainfall data and applied to the Algarve region, Portugal

Journal of Hydrology, Vol. 250, No. 1-4. (September 2001), pp. 12-18,


One of the best indicators of the potential erosion risks is the rainfall–runoff erosivity factor (R) of the revised universal soil loss equation (RUSLE). Frequently, however, there is not enough data available to compute the R value, and other parameters, such as the modified Fournier index (Fmod), are used instead. But RUSLE is less effective if only the alternative procedures exist. One of the major discrepancies between R and the alternative parameters is time resolution: individual storms are used to calculate ...
