Wildfire Management – Recent Experiences on the Ground and how Remote Observation can add to the Picture

For all the recent progress in Earth Observation technologies, wildfires remain a serious problem that poses ever-increasing challenges to our ingenuity. Minimizing their often-dramatic environmental and human impacts will require a smart combination of technology, political decision, and willingness to accept changes in our own individual and collective options as societies. In order to show how fire hazard is threatening many parts of the world on a recurrent basis, details are provided on the recent severe 2013 fire season in Portugal, along with background information on remote sensing of wildfires and related disaster risk management challenges.

Space-based Information Support for Prevention and Recovery of Forest Fire Emergency in the Mediterranean Area

The European Commission has recently adopted an approach to natural and man-made disasters that emphasizes joint efforts over separate national ones. The Prevention and Recovery of Forest Fire Emergency in the Mediterranean Area (PREFER) project will stimulate coordination among countries on forest fires prevention by providing timely Earth observation products based on all available space-borne sensors within the next four years.

Mitigation of Forest Fires at the Municipal Level: The Case of Mirandela, Portugal

The municipality of Mirandela, in northern Portugal, lies in an area prone to forest fires. The municipality is developing a dynamic plan with a forest fire risk reduction policy adapted to local conditions. Its planning process offers valuable lessons for cities and towns facing similar challenges

Live Fuel Moisture Content Derived from Remote Sensing Estimates in Temperate Shrublands and Grasslands

map

The paper proposes a new approach to estimating live fuel moisture content, a key variable in fire danger assessment. Our proposed model uses an alternative inversion procedure based on the look-up table technique. The model outperforms already-published Mediterranean models in estimated moisure content in the temperate grassland and shrubland of Spain’s Eurosiberian ecosystem.

Maps of a Wildfire Tragedy Show Why Escape Was Impossible

Arizona’s Yarnell Hill Fire was the deadliest wildfire in 80 years. New maps from the official investigation show why the fire was not survivable.

Impacts of Snow Water Equivalent on Wildfire Events in the Sierra Nevada

map

As the climate warms, increasing amounts of Sierra Nevada precipitation will turn from snow to rain, effectively lengthening and intensifying the fire season. Our data, which demonstrates the relationships among snowpack, soil properties, and wildfires, may improve predictive risk assessments.

Mapping Post-Wildfire Neighborhood Recovery: Integrating Spatial Video with GIS for Data Collection and Analysis

map


Until recently, no systematic, dynamic, and cost-effective data collection strategy has been available for use in the study of post-disaster neighborhoods. In order to address this concern, we employed a geospatial approach, “spatial video,” which links video with coordinates acquired by a Global Positioning System receiver. This advance enables new study of the dynamic spatial and temporal scales of post-wildfire recovery.

Amplified Fire Occurrences in Response to Drought and Vegetation Stress in the Western Ghats of India

map

This study demonstrates the importance of the intensity and severity of drought in contributing to anomalous fire events, an important driver of global fire regimes. While spatial and temporal analysis of fires’ response to droughts indicates the vulnerability of all land cover types, the primary wet evergreen and secondary moist deciduous forests are particularly at risk.

Amplified Fire Occurrences in Response to Drought and Vegetation Stress in the Western Ghats of India

By N. Kodandapani Asian Nature Conservation Foundation, Center for Ecological Sciences, Bangalore, India ABSTRACT There is uncertainty regarding the extent to which drought, fuel availability, and ignition sources contribute to the global fire regime. In 2004, sharply increased fire activity followed a severe drought, highlighting the importance of drought–fire linkages in the Western Ghats hotspot […]

The impact of an ever-changing territory on wildfire hazard assessment

map

Attempts have been made to model wildfire susceptibility by means of different methods. This paper focuses on susceptibility as a property of a given territory, under the assumption that even though a land parcel is not static in nature, it is sufficiently stable to support a structural approach.
