We designed an integrated platform for early prediction of meteorological fire risk. The system is operative since the end of 2014 and estimates the fire danger index automatically, based on the 72 hours forecast of the Weather Research and Forecast (WRF) model. Though the system is in experimental phase, the first results showed a quite acceptable...

Se utilizó un método de mapeo basado en la localización de las edificaciones y la disponibilidad de vegetación combustible. Se trabajó sobre una capa raster base (10 x 10 m) y para cada píxel se calculó la den...
Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012. However, little is known about the spatial and temporal patterns of fires and their relationship with climate and vegetation in this area. Such information is of great value for fire risk assessment and the develop...
El rol del suelo como regulador del balance de agua se encuentra considerablemente alterado en ambientes urbanos a causa del pavimento y las edificaciones, que interfieren con el proceso de infiltración. En este contexto, las áreas verdes adquieren importancia al actuar como focos de absorción de agua. El objetivo del presente trabajo fue evaluar l...
En el año 2020, las Sierras de Córdoba registraron la temporada de incendios más extrema de la memoria colectiva reciente, con daños ecológicos y socioeconómicos severos. En este trabajo se cartografiaron los incendios de 2020 utilizando imágenes Sentinel 2, se comparó la temporada con estadísticas históricas en función del número de incendios, la...
Background
Pyrogeography is a major field of investigation in wildfire science because of its capacity to describe the spatial and temporal variations of fire disturbance. We propose a systematic pyrogeographic analytical approach to cluster regions on the basis of their pyrosimilarities. We employed the Affinity Propagation algorithm to cluster py...

Aims : Trithrinax campestris is one of the palm species with the southernmost distribution in the Neotropics. Despite that the vegetation types in which T. campestris occurs are nowadays heavily threatened by land use and land cover changes, their floristic composition and structure are still to be documented. In order to characterize T. campestris...
The main goal of this investigation was to assess landslides in the steep West-facing slope of the Sierras Chicas mountains in central Argentina using two complementary approaches: Differential SAR interferometry (DinSAR) and statistical modeling. The combination of the geological characteristics of the area, wildfires, intense rainfall events and...
In mountain ecosystems, vegetation distribution along elevation has been traditionally interpreted in terms of the decreasing temperature from base to top, but wildfires may co-vary with the elevation gradient, also playing an important role. In the mountains of central Argentina (500-2800 m a. s. l.) wildfires are one of the main disturbances, whi...

The air pollution caused by the immense wildfire that occurred in Northeast Patagonia, Argentina in the summer 2016-2017 is presented in this work through the assessment of ground-based data, satellite measurements and modeled concentrations of NO, NO 2 , CO, PM2.5, PM10 and AOD. The data was obtained from a monitoring station placed in Bahia Blanc...
The wildland-urban interface (WUI) is a focal area for human environmental conflicts including wildfires. The WUI grows because new houses are built, and in developed countries, housing growth can be very rapid in areas with natural amenities. However, it is not clear if natural amenity-driven WUI growth is limited to developed countries, or also p...
Fuel moisture content (FMC) is an important fuel property for assessing wildfire hazard, since it influences fuel flammability and fire behavior. The relationship between FMC and fire activity differs among land covers and seems to be a property of each ecosystem. Our objectives were to analyze pre-fire FMC among different land covers and to propos...

Monitoreo satelital de la calidad del agua en una cuenca y su relación con incendios, precipitaciones y crecimiento urbano Abstract-Water has historically been considered a renewable resource, however in the last century a sustained degradation of its quality has been observed, both in continental and oceanic systems due to the anthropic impact. Ad...
Wildfires represent an important issue in Argentina and their management strongly depends on the possibility of having all the resources ready to be used at the right time. To this purpose, the availability of fire danger indices becomes essential. In previous work, the authors implemented the Australian index FFDI (Forest Fire Danger Index) for th...
In this paper we present the operational implementation of a fire danger mapping system based on Numerical Weather Prediction and space derived Moisture Content of Live Fuels (LFMC) for the Chaco Serrano sub-region. The system is operative since the end of 2016 and estimates the fire danger index automatically (without any man operator), based on t...
p>Natural fire regimes have been modified; therefore robust post-fire monitoring tools are needed to understand the post-fire recovery process. Satellites with high temporal resolution allow us to build time series of vegetation indices for monitoring post-fire vegetation recovery. One of the techniques used is to compare the time series of a burne...

Wildfires are a major threat to people and property in Wildland Urban Interface (WUI) communities worldwide, but while the patterns of the WUI in North America, Europe and Oceania have been studied before, this is not the case in Latin America. Our goals were to a) map WUI areas in central Argentina, and b) assess wildfire exposure for WUI communit...
Los objetivos fueron calibrar el simulador de incendios FARSITE en el Chaco Serrano e identificar los modelos de combustibles estándar más apropiados para describir la vegetación. Se simularon tres incendios de diferente tamaño (87, 1932 y 7910 ha) y se analizó la coincidencia espacial entre el área quemada real y la simulada. FARSITE tuvo un mejor...
RESUMEN La frecuencia y propagación de incendios a lo largo del paisaje se hallan íntimamente ligados a la inflamabilidad de la matriz de combustible vegetal. A nivel mundial, los ecosistemas de sabana, han sufrido fuertes cambios en la estructura de la matriz de combustible vegetal. Por lo tanto los objetivos del presente trabajo fueron estudiar l...
Moisture content of live fuels (LFMC) is one of the main factors determining fuel flammability and, therefore, a key indicator of fire danger. In this study, we modeled the relationship between spectral indices derived from satellite imagery and field estimations of LFMC in the Chaco Serrano subregion; then, we analyzed the relationship between fir...

Questions
Question (1)
La mayor exposición humana al fuego se da en áreas urbanizadas de baja densidad y donde aumenta la disponibilidad de vegetación combustible. Si bien es bastante común traducirlo como Interfaz Urbano Rural, hay críticas al uso de esa expresión (a mi criterio bien fundadas), ya que la palabra rural hace referencia a un ambiente de tipo agrícola, que no suelen ser tan problemáticos en la propagación del fuego. También es frecuente (aunque un poco menos) hablar de Interfaz urbano-forestal, aunque el problema del fuego en cercanías de viviendas se da también en ambientes que no son forestales (Ej: arbustales y pastizales). Por otro lado, traducirlo como Interfaz Urbano-Natural dejaría de lado áreas vegetadas que tengan intervención humana (plantaciones forestales, ¿plantaciones frutales (pienso en olivos por ejemplo)?
La traducción que me parece mas adecuada sería Interfaz urbano-silvestre, aunque la palabra "silvestre" no de uso tan frecuente en castellano y también dejaría de lado las plantaciones.
