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.
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.
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, ÛÏspatial video,Û 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.
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 droughtÛÒfire linkages in the Western Ghats hotspot of biodiversity. The spatial extent … Read More
Climate change is contributing to larger wildfires and a longer fire season, making the need for near-real time and ultra-precise maps of fires more critical than ever. A team at the National Interagency Fire Center (NIFC), in Boise, Idaho, (USA), is responding to that demand with new and better mapping technologies.
Noise from various sources, such as clouds, is present in satellite observations. This noise, as well as low contrast in satellite images, prevents automatic tools from processing each image independently. We developed an approach which processes all images simultaneously and enforces the constraint that the burned areas can only grow in time. This allows the exploitation of temporal information not available for a single image.
The National Observatory of Athens (NOA) in Greece offers operational Earth Observation services for disaster management of forest wildfire. Dedicated systems offer stakeholders online access to robust, accurate and fully operational Web-based tools to assist their Emergency Response and Emergency Support actions.
