Les incendies en Méditerranée sont associés aux événements de sécheresse, forte température et vents violents. En Tunisie, les périodes de Sirocco apparaissent comme les événements climatiques principaux qui génèrent de fortes températures et les plus grands incendies. Le nombre d'événements sirocco annuel est donc fortement corrélé à la surface to...

We analyzed trends of air temperature across the Cévennes National Park in Southern France, a mid-altitude coastal mountain experiencing a rapid spread of forests at the expense of rangelands and submitted to Mediterranean Sea influences and so, impacted by local and regional processes of climate change. Since 1980, April to June warming trend reac...

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%...

Fires create substantial ecosystem disturbances, which affect biodiversity and climate processes. Previously, satellite-derived burned areas were assessed, and fire patches and morphological traits related to fire spread functions identified. The cut-off value in days is a critical parameter for the algorithms used to identify fire patches, as it i...

Marine microcharcoal records provide invaluable information to understand changes in biomass burning and its drivers over multiple glacial and interglacial cycles and to evaluate fire models under warmer climates than today. However, quantitative reconstructions of burnt area, fire intensity and frequency from these records need calibration studies...

Northern Eurasia is currently highly sensitive toclimate change. Fires in this region can have significant im-pacts on regional air quality, radiative forcing and black car-bon deposition in the Arctic which can accelerate ice melt-ing. Using a MODIS-derived burned area dataset, we reportthat the total annual area burned in this region declined by5...

Droughts can have strong environmental and socioeconomic impacts in the Mediterranean region, in particular for countries relying on rain-fed agricultural production, but also in areas in which irrigation plays an important role and in which natural vegetation has been modified or is subject to water stress. The purpose of this review is to provide...

Wildfire activity is expected to increase across the Mediterranean Basin because of climate change. However, the effects of future climate change on the combinations of atmospheric conditions that promote wildfire activity remain largely unknown. Using a fire-weather based classification of wildfires, we show that future climate scenarios point to...
Article

With hot and dry summers, the Mediterranean basin is affected by recurrent fires. While drought is the major driver of the seasonal and inter-annual fire distribution in its northern and mildest climate conditions, some extreme fire events are also linked to extreme winds or heat waves. The southern part of the Mediterranean basin is located at the...

Fire disturbance is a significant component of the climate system. Analysis of satellite-derived burned areas has allowed the identification of fire patches and their morphology as a new resource for tracking fire spread to improve fire models used to assess the impact of fires on climate and the carbon cycle. A critical parameter of the flood-fill...

Sampling efficiency is crucial in order to overcome the data crisis in biodiversity and to understand what drives the distribution of rare species. Adaptive niche‐based sampling (ANBS) is an iterative sampling strategy that relies on the predictions of species distribution models (SDMs). By predicting highly suitable areas to guide prospection, ANB...

Dernièrement la Tunisie a vécu une forte augmentation des surfaces brûlées. Et la prévention aux incendies de forêt est aujourd'hui devenu une nécessité. Pour la période 1985-2010, nous avons fait un calcul d'un indice de sécheresse (DI) pour la Tunisie (zone forestière). Nous avons constaté que plus un gouvernorat est occupé par de la forêt, plus...

This study was conducted to investigate the effects of water deficit stress and shading on two wheat cultivars (Triticum durum Desf. cv Om Rabiaa and cv Maali). Comparison was based on growth, leaf water relations, photosynthetic pigments and the accumulation of organic solute. In both cultivars, water stress deficit significantly decreased total d...

Wildfires are an intrinsic component in the dynamic and functioning of Mediterranean ecosystems. Based in the varying constraint hypothesis, mediterranean climate consitions can vary between fuel limited conditions to moisture limited, while heat waves can enhance fire hazard to extreme events. However, long term-fire history reconstructions illust...

Fire has a diverse range of impacts on Earth's physical and social systems. Accurate and up to date information on areas affected by fire is critical to better understand drivers of fire activity, as well as its relevance for biogeochemical cycles, climate, air quality, and to aid fire management. Mapping burned areas was traditionally done from fi...

Vegetation fires are an important process in the Earth system. Fire intensity locally impacts fuel consumption , damage to the vegetation, chemical composition of fire emissions and also how fires spread across landscapes. It has been observed that fire occurrence, defined as the frequency of active fires detected by the MODIS sensor, is related to...

Fires account for approximately 25-35% of emissions on Earth vegetation, thus affecting the abundance and diversity of organisms and strongly influencing climate processes. Analyses of satellite-derived products have recently provided a general picture of fire disturbance at the global scale, but the current level of information, relying on the bur...

Article
The Mediterranean evergreen oak coppices of Southern Europe are increasingly vulnerable to drought because of both the ongoing climate change that increases drought length and intensity, and the lack of forest management that induces a structural aging of the stands. Decreasing stand density through thinning has been widely regarded as a means to i...

Long-term fire history reconstructions provide fruitful information in the context of global change. Global remotely-sensed burned areas offer a uniform estimate of fire regimes worldwide,but hardly capture small fire events and cover only the last 20 years. Burned areas from nationalstatistics often lack credibility due to discrepancies in fire re...

Pastoral farming systems have always adapted to the seasonal availability of forage resources and climate variability by moving animals. However, the role of animal mobility as a possible mitigating strategy in response to climate change has not been clearly documented. To understand this role, we investigated (i) the major methodological challenge...

Mediterranean shrublands are generally water-limited and fire-driven ecosystems. Seed-based post-fire regeneration may be affected by varying rainfall patterns, depending on species' sensitivity to germinate under water stress. In our study, we considered the germination response to water stress in four species from multiple sites across the Medite...

A better understanding of stem growth phenology and its climate drivers would improve projections of the impact of climate change on forest productivity. Under a Mediterranean climate, tree growth is primarily limited by soil water availability during summer, but cold temperatures in winter also prevent tree growth in evergreen forests. In the wide...
