Article
Full-text available
Forest fires preparedness strategies require the assessment of spatial and temporal variability of fire danger. While several tools have been developed to predict fire occurrence and behaviour from weather data, it is acknowledged that fire danger models may benefit from direct assessment of live fuel condition, as allowed by Earth Observation tech...
Article
Full-text available
Operational forest fire danger rating systems rely on the recent evolution of meteorological variables to estimate dead fuel condition. Further combining the latter with meteorological and environmental variables, they predict fire occurrence and spread. In this study we retrieved live fuel condition from MODIS multispectral measurements in the nea...
Article
Full-text available
Forest fires are a major source of ecosystem disturbance. Vegetation reacts to meteorological factors contributing to fire danger by reducing stomatal conductance, thus leading to an increase of canopy temperature. The latter can be detected by remote sensing measurements in the thermal infrared as a deviation of observed land surface temperature (...

Moisture dictates vegetation susceptibility to fire ignition and propagation. Various spectral indices have been proposed for the estimation of equivalent water thickness (EWT), which is defined as the mass of liquid water per unit of leaf surface. However, fire models use live fuel moisture content (LFMC) as a measure of vegetation moisture. LFMC...
Article
Many dryland rivers are terminal systems, with small channels undergoing prominent downstream size reductions before ending on channelless floodplains, in wetlands, or at playa margins. Spaceborne Digital Elevation Models (DEMs) provide potential for assessing subtle topographic and hydrodynamic changes in these low-gradient, low-relief settings, b...

Full-text available
In Mediterranean countries, in the year 2017, extensive surfaces of forests were damaged by wildfires. In the Vesuvius National Park, multiple summer wildfires burned 88% of the Mediterranean forest. This unprecedented event in an environmentally vulnerable area suggests conducting spatial assessment of the mixed-severity fire effects for identifyi...
Article
Full-text available
In some internally-draining dryland basins, ephemeral river systems terminate at the margins of playas. Extreme floods can exert significant geomorphological impacts on the lower reaches of these river systems and the playas, including causing changes to flood extent, channel-floodplain morphology, and sediment dispersal. However, the characterizat...
Chapter
Satellite observations of the terrestrial biosphere cover a period of time sufficiently extended to allow the calculation of a reliable climatology. The latter is particularly relevant for studies of vegetation response to climate variability. Observations from space of the land surface are hampered by clouds at shorter wavelength and affected by w...
Conference Paper
Full-text available
In this paper data from different sources have been used to monitor and characterize in a more extensive way a site of interest. The objective has been to implement a broad monitoring system through the combination of different data sources in order to control the whole area. Terrestrial surveying systems and aerial images have been combined with s...
Conference Paper
Full-text available
Several spectral indices based on measurements in the optical domain have been proposed for the estimation of equivalent water thickness (EWT), which is defined as the mass of liquid water per unit of leaf surface. However, fire models rely on the live fuel moisture content (LFMC) as a measure of vegetation moisture. LFMC is defined as the ratio of...
Conference Paper
Full-text available
Prolonged heat and absence of rainfall drive vegetation into water stress conditions that lead to an increase of its temperature. Since stressed vegetation is more prone to fire, it is expected that remote sensing mapping of temperature anomalies might be a viable tool to predict fire hazard. The identification of these anomalies requires the prior...
Article
Various factors contribute to forest fire hazard, and among them vegetation moisture is the one that dictates susceptibility to fire ignition and propagation. The scientific community has developed a number of spectral indices based on remote sensing measurements in the optical domain for the assessment of vegetation equivalent water thickness (EWT...

Article
The objective of the present research was the characterisation of fire hazard using temporal sequences of land surface temperature (LST) derived from Terra-MODIS measurements. The investigation was based on a complete sequence of MODIS LST data from 2000 to 2006 on Campania (Italy) and on a dataset of fires officially recorded in the area in the sa...
Conference Paper
Full-text available
Many authors demonstrated the role of remote sensing in the assessment of vegetation equivalent water thickness (EWT), which is defined as the weight of leaf liquid water per unit of leaf surface. However, fire models rely on the fuel moisture content (FMC) as a measure of vegetation water. FMC is defined as the ratio of the weight of the liquid wa...
Conference Paper
Full-text available
The increasing demand for effective forest fire prevention instruments has faced operational and future Earth observation instruments with the challenge of producing updated and reliable maps of vegetation moisture. Various empirical band-ratio indexes have been proposed so far, based on multispectral remote sensing data, that have been found to be...
Article
A study was carried out to investigate whether basic soil properties can be predicted by using reflectance spectrometry (RS) in the visible-near infrared- shortwave infrared (VIS-NIR-SWIR, 350-2500 nm) region using an artificial neural network (ANN) approach. Over 330 soil samples from three agro- forestry areas, representative of the pedo-environm...
Article
Forest fires are one of the major environmental hazards in Mediterranean Europe. Biomass burning reduces carbon fixation in terrestrial vegetation, while soil erosion increases in burned areas. For these reasons, more sophisticated prevention tools are needed by local authorities to forecast fire danger, allowing a sound allocation of intervention...
Conference Paper
Vegetation moisture is a key parameter in fire risk modeling. Many authors have demonstrated the role of remote sensing in the assessment of the equivalent water thickness (EWT), which is defined as the weight of liquid water per unit of leaf surface. However, forest fire danger models rely on fuel moisture content (FMC) as a measure of vegetation...
Article
A field experiment was carried out to assess the effects of irrigation with highly saline (T1 treatment), moderately saline (T0.5) and non saline (T0) water on soil and eggplant (Solanum melongena) properties and spectral response. The investigated soil was a clay-loam Alfic Xerarent, with swelling clay minerals (smectites). After 5 years of irriga...
Article
Forest fires are one of the major environmental issues in large areas of Southern Italy, and more generally in Mediterranean Europe. Biomass burning reduces carbon fixation in terrestrial vegetation, while risk of soil erosion increases in burned areas. The premier action against fires is prevention, and in this context fire risk mapping is an inva...
Article
In the present work we show the potential of multiangular hyperspectral PROBA-CHRIS data to estimate aerosol optical properties over dense dark vegetation. Data acquired over San Rossore test site (Pisa, Italy) have been used together with simultaneous ground measurements. Additionally, spectral measurement over the canopy have been performed to de...
Article
Full-text available
Measurements of spectro-directional radiances done with the imaging spectrometer CHRIS on-board the agile platform PROBA are being used to determine key properties of terrestrial vegetation at the appropriate spatial resolution. These data on vegetation properties can then be used to improve the accuracy and the parameterizations of models describi...
