Temperate regions around the world are experiencing longer fire weather seasons, yet trends in burned area have been inconsistent between regions. Reasons for differences in fire patterns can be difficult to determine due to variable vegetation types, land use patterns, fuel conditions, and human influences on fire ignition and suppression. This st...

Fire has been a widely used tool in habitat and landscape management, mainly associated with land use dynamics of deforestation, pasture renewal, hunting and reclaiming new agriculture and rangeland areas. Ancient societies followed norms and rules regarding the used of fire. However, as these societies developed and land ownership changed, the con...

Recent projections suggest that wildfires will occur more often and with higher intensity due to the changing climate. In this context, it is vital to educate the population to be ready and prepared to deal with these events. This book chapter reviews the state of the art of educational materials on wildfires worldwide that are available online. A...

The poster presented at the IUFRO 2024 Congress discusses current trends in the management of Portuguese community forest areas (baldios), highlighting the development of new governance models and the challenges faced in managing these areas. It also emphasizes the importance of creating clusters of baldios and forest certification to improve admin...

This report aims to identify pre-fire landscape composition, dynamics and configuration associated with the occurrence of Extreme Wildfire Events (EWE) in Europe in 2000-2022. A set of 137 EWE were compiled into a database, using literature revision and statistical analyses. Corine Land Cover (CLC) data was used to analyze landscape composition, co...

The global rise in issues related to the invasion of alien tree species is becoming increasingly prominent. Genus Acacia is one of the most pervasive invaders among the non-native flora introduced to Portugal over the centuries. This research aimed to pinpoint the key players engaged in its management, their expertise, and the methodologies applied...

Traditional, rural, native, or indigenous fire has coexisted with lightning-caused fire since the origin of Humanity. In Portugal, several uses of fire played an essential role in supporting communities from the settlement of the Portuguese territory within complex agrosilvo-pastoral systems. Previous studies approached traditional fire knowledge f...

Os terrenos comunitários portugueses - baldios, têm uma história centenária. Desde os seus primórdios, as populações rurais locais usaram estes terrenos para garantir a sua subsistência, o que implicou uma alteração progressiva da paisagem através da utilização de florestas, campos agrícolas, e pastagens. Assim, foram-se desenvolvendo as vertentes...

A paisagem portuguesa tem uma longa história de alterações de uso e ocupação do solo, e o seu conhecimento contribui positivamente para o planeamento e definição de políticas públicas a longo prazo. O Mapa Agrícola e Florestal 1951-80, recentemente publicado em formato vetorial e com uma nomenclatura compatível com a série cartográfica da Carta de...

The reduction of forest biomass decreases wildfire intensity and severity, particularly if applied to a large scale. However, mechanical fuel management treatments are expensive and do not guarantee a financial return to the forest owners. The project “Added value of forest biomass as a tool in fire risk management - Value2Pre-vent” (PCIF/GVB/0057/...

Fuel management for wildfire risk prevention generally lacks economic sustainability. In marginal areas of southern Europe, this limits fuel treatment programs from reaching the critical mass of required treated area to modify landscape flammability, the fire regime and its impacts. This study investigates key fuel management initiatives for wildf...

Pyrosilviculture and understory fuel management to reduce forest stand and landscape flammability represent loss-making interventions from an economic point of view. Consequently, prevention is carried out above all on public property and with public funds (e.g. Rural Development Programs), while the interest of the private individual for preventio...

Bulk density for shrubs and tree crowns is an important variable, useful for many purposes, namely estimations for biomass and carbon sequestration and potential fire behavior prediction. In the latter case, bulk density is required to predict the rate of spread and intensity of crown fires. However, bulk density information is scarce. The estimati...

In marginal areas of southern Europe, this limits fire prevention programs to reach the critical mass of interventions required to modify landscape flammability, the fire regime and its impacts.This study investigates key fuel management initiatives for wild...

Forests are increasingly susceptible to wildfires due to land abandonment, fragmentation, lack of forest management, and agricultural burns. The impacts of climate change, with longer heat waves and the extension of the summer season, creates the conditions for catastrophic wildfire seasons in many countries. The drivers that increase wildfire risk...

This publication is the final report summarizing main results of RECIPE (Reinforcing Civil Protection capabilities into multi-hazard risk management) project, co-funded by European Union Humanitarian Aid and Civil Protection (UCPM-2019-PP-AG).

La prevención de incendios forestales tiene como ejes principales reducir tanto el riesgo de ignición como la capacidad de propagación de los incendios. En ambos objetivos, la gestión del combustible forestal es fundamental. Tradicionalmente, las actividades agropecuarias y forestales han contribuido de forma indirecta a esa gestión a escala de pai...

Rural fires have historically been one of the main factors of landscape change in the inner mountain areas of the Iberian Peninsula. Although the interaction of fire and rural landscape throughout the 20th century has been extensively studied in the Iberian Peninsula, long-term historical knowledge is limited and can provide a valuable context to u...

La Península Ibérica cuenta con una larga historia de incendios forestales. Es el caso del Sistema Central, desde la Sierra de Estrela en Portugal a la Sierra de Ayllón en España, aunque las causas humanas y el régimen de incendios difieren en función del contexto ambiental, político y socioeconómico en uno y otro extremo de la cordillera. La valid...

Wildfires in the Iberian Peninsula were large and frequent in the second half of the 20th century. Land use and land cover (LULC) also changed greatly. Our aim was to understand the relationship between LULC and fire in the western and eastern ends of the Iberian Central Mountain System. We compared two case study landscapes, the Estrela massif and...

Fire is one of the main disturbance factors shaping the landscape, and landscape is a key driver of fire behavior. Considering the role played by land use and land cover (LULC) changes as the main driver of landscape dynamics, the aim of this study was to calculate and analyze (i) the real impact of fire on LULC changes and (ii) how these LULC chan...

Wildfires have been a major landscape disturbance factor throughout history in inland mountain areas of Spain. This paper aims to understand the interaction of fire regimes and landscape dynamics during the last two centuries within a socio-spatial context. The study area selected for this historical and spatial analysis is the Ayllón massif, in th...
