Fire Immediate Response System Workshop Report

California's recent wildfires, exacerbated by extreme weather conditions, have focused the nation's attention on the problem of managing fire at the wildland urban interface. With the goal of understanding how new or re-imagined technologies could improve early fire detection and response, the Gordon and Betty Moore Foundation hosted a "Fire Immediate Response System" workshop (April 24 -26, 2019). The workshop identified the following priorities and recommendations, which are described in detail in the report.* Develop a shared, integrated platform for diverse sources of data, intelligence and information* Conduct new wildfire risk assessments with high-resolution mapping technologies* Improve scientific understanding of "megafires" through retrospective analysis* Enhance fire behavior models and associated inputs for real-time prediction* Perform a cost-benefit analysis of investment in solutions vs. reactive management* Target investments in the development and adoption of new technologies* Expand multi-stakeholder dialogue, collaboration and actio

Summary of the Active Microwave Workshop, chapter 1

An overview is given of the utility, feasibility, and advantages of active microwave sensors for a broad range of applications, including aerospace. In many instances, the material provides an in-depth examination of the applicability and/or the technology of microwave remote sensing, and considerable documentation is presented in support of these techniques. An assessment of the relative strengths and weaknesses of active microwave sensor data indicates that satisfactory data are obtainable for several significant applications

Satellite Remote Sensing contributions to Wildland Fire Science and Management

No funding was received for this particular review, but support research was funded by the European Space Agency’s Climate Change Initiative Programme to Dr. Chuvieco.This paper reviews the most recent literature related to the use of remote sensing (RS) data in wildland fire management. Recent Findings Studies dealing with pre-fire assessment, active fire detection, and fire effect monitoring are reviewed in this paper. The analysis follows the different fire management categories: fire prevention, detection, and post-fire assessment. Extracting the main trends from each of these temporal sections, recent RS literature shows growing support of the combined use of different sensors, particularly optical and radar data and lidar and optical passive images. Dedicated fire sensors have been developed in the last years, but still, most fire products are derived from sensors that were designed for other purposes. Therefore, the needs of fire managers are not always met, both in terms of spatial and temporal scales, favouring global over local scales because of the spatial resolution of existing sensors. Lidar use on fuel types and post-fire regeneration is more local, and mostly not operational, but future satellite lidar systems may help to obtain operational products. Regional and global scales are also combined in the last years, emphasizing the needs of using upscaling and merging methods to reduce uncertainties of global products. Validation is indicated as a critical phase of any new RS-based product. It should be based on the independent reference information acquired from statistically derived samples. The main challenges of using RS for fire management rely on the need to improve the integration of sensors and methods to meet user requirements, uncertainty characterization of products, and greater efforts on statistical validation approaches.European Space Agenc

Unmanned Aerial Vehicles (UAVs) in environmental biology: A Review

Acquiring information about the environment is a key step during each study in the field of environmental biology at different levels, from an individual species to community and biome. However, obtaining information about the environment is frequently difficult because of, for example, the phenological timing, spatial distribution of a species or limited accessibility of a particular area for the field survey. Moreover, remote sensing technology, which enables the observation of the Earth’s surface and is currently very common in environmental research, has many limitations such as insufficient spatial, spectral and temporal resolution and a high cost of data acquisition. Since the 1990s, researchers have been exploring the potential of different types of unmanned aerial vehicles (UAVs) for monitoring Earth’s surface. The present study reviews recent scientific literature dealing with the use of UAV in environmental biology. Amongst numerous papers, short communications and conference abstracts, we selected 110 original studies of how UAVs can be used in environmental biology and which organisms can be studied in this manner. Most of these studies concerned the use of UAV to measure the vegetation parameters such as crown height, volume, number of individuals (14 studies) and quantification of the spatio-temporal dynamics of vegetation changes (12 studies). UAVs were also frequently applied to count birds and mammals, especially those living in the water. Generally, the analytical part of the present study was divided into following sections: (1) detecting, assessing and predicting threats on vegetation, (2) measuring the biophysical parameters of vegetation, (3) quantifying the dynamics of changes in plants and habitats and (4) population and behaviour studies of animals. At the end, we also synthesised all the information showing, amongst others, the advances in environmental biology because of UAV application. Considering that 33% of studies found and included in this review were published in 2017 and 2018, it is expected that the number and variety of applications of UAVs in environmental biology will increase in the future

Space assets and technology for bushfire management

The financial, emotional, and ecological impacts of bushfires can be devastating. This report was prepared by the participants of the Southern Hemisphere Space Studies Program 2021 in response to the topic: “How space assets and technologies can be applied to better predict and mitigate bushfires and their impacts.” To effectively reach the diverse set of stakeholders impacted by bushfires, Communication was identified as a key enabler central to any examination of the topic. The three pillars “predict”, “mitigate” and “communicate” were identified to frame the task at hand. Combining the diverse skills and experience of the class participants with the interdisciplinary knowledge gained from the seminars, distinguished lectures, and workshops during the SHSSP21 program, conducted a literature review With specific reference to the 2019-20 Australian fire season, we looked at the current state of the art, key challenges, and how bushfires can be better predicted and mitigated in the future. Comparing this to the future desired state, we identified gaps for each of the three domains, and worked across teams to reach consensus on a list of recommendations. Several of these recommendations were derived independently by two or more of the three groups, highlighting the importance of a holistic and collaborative approach. The report details a number of recommendations arising from this Where applicable, we also aligned our discussion with the experience and lessons from other countries and agencies to consider,learn from and respond to the international context, as others develop systems using space technology to tackle similar wildfire issues

Technology for the Future: In-Space Technology Experiments Program, part 2

The purpose of the Office of Aeronautics and Space Technology (OAST) In-Space Technology Experiments Program In-STEP 1988 Workshop was to identify and prioritize technologies that are critical for future national space programs and require validation in the space environment, and review current NASA (In-Reach) and industry/ university (Out-Reach) experiments. A prioritized list of the critical technology needs was developed for the following eight disciplines: structures; environmental effects; power systems and thermal management; fluid management and propulsion systems; automation and robotics; sensors and information systems; in-space systems; and humans in space. This is part two of two parts and contains the critical technology presentations for the eight theme elements and a summary listing of critical space technology needs for each theme
