m topography, drainage, and soil texture. Such homogeneity enabled the researchers to detect the effects of differing land-use on the structure and composition of the vegetation. Also motivating the study was the rarity of pitch pine-scrub oak communities. They support several rare plant and animal species but have been substantially degraded by industrial, commercial, and residential developme...

ethods: A random-digit-dial survey was conducted about home safety with 1003 respondents representing households in the continental United States. Descriptive statistics assess the prevalence of risk and protective factors for fires, burns, and carbon monoxide overall, and by demographic characteristics, household structure, region, and residential tenure. The data were weighted to adjust for n...

Fires have raged across southern Europe during the exceptional heat of this summer but in Greece, where they have been particularly severe and widespread, they caught the authorities by surprise. They have been occurring over weeks from late June in the forests of the north to Crete in the south. They are doubly troubling because of Greece's dramatic biodiversity — more than 25 per cent of an e...

Fast detection of forest fires is a great concern among environmental experts and national park managers because forest fires create economic and ecological damages and endanger human lives. For effective fire control and resource preparation, it is necessary to predict fire occurrences in advance and estimate the possible losses caused by fires. For this purpose, real-time sensor data of weath...

Liquid fuels(hydrocarbon and peroxide)are flammableand there is a risk of pool fires during their storage and transportation. In order to measure and develop effective methods for protection and considering safety distances, experimental studies and CFD simulations of pool fire of two hydrocarbon fuels (i.e. gasoline and kerosene) and peroxide (TBPB (tert-butyl peroxybenzoate)) were performed. ...

Forest fires represent a quite complex environment and an accurate prediction of the fires generated is crucial when trying to react quickly and effectively in such a critical situation. In this study, an hybrid system is applied to predict the evolution of forest fires. The Case-Based Reasoning methodology combined with a summarization of SOM ensembles algorithm has been used to face this prob...

An increasing number of end-users looking for ground data about fire activity in regions where accurate official datasets are not available adopt a free-of-charge global burned area (BA) and active fire (AF) products for applications at the local scale. One of the pressing requirements from the user community is an improved ability to detect small fires (less than 50 ha), whose impact on terres...

There has been increasing interest in the use of summer fires to limit woody plant encroachment on grasslands, but information regarding effects of such fires on perennial grass recovery and annual forb production is also needed. Our objective was to examine effects of fire seasonality and intensity on the woody legume honey mesquite (Prosopis glandulosa Torr.), the C4 midgrass tobosagrass (Ple...

Biomass burning has important impacts on atmospheric chemistry and climate. Fires in tropical forests and savannas release large quantities of trace gases and particulate matter. Combustion of biofuels for cooking and heating constitutes a less spectacular but similarly widespread biomass burning activity. To provide the groundwork for a quantification of this source, we determined in rural Zim...

This paper provides evidence that the combination of land-use restrictions and an increasing demand for housing can create incentives to induce forest fires as a means to circumvent regulation and increase the supply of land available for residential construction. I estimate the effect of the price of housing on the incidence of forest fires using Spanish data by region for 1991-2005. The resul...
