About this Research Topic

Background

The world we live in has experienced several ecological disasters, most of them caused by direct human actions, which have been intensifying particularly in the past few decades. In particular, forest fire is a natural hazard, whose intensity and frequency have recently been increased, thus affecting forest ecosystems with serious consequences on the environment, society and economy. In addition, drier, warmer weather caused by climate change creates conditions for extreme and widespread biomass burning. Spaceborne and airborne remote sensing Earth observation platforms with improved instruments (including optical, thermal infrared, microwave sensors) have rapidly evolved in the last decades, thus providing an invaluable data source, to understand, monitor and respond to wildfires, at various spatial and temporal scales. Optical and SAR data with global coverage and frequent revisits have become freely available, thus playing a critical role in wildfire monitoring. Moreover, LiDAR has the potential to penetrate the forest canopy, thus emerging as a powerful active sensing tool for assessing both landscape fire hazard and fire effects on vegetation at fine-grained scale. Together to remote sensing analyses, experimental analyses of fire effects are important to have a complementary information about the impact of fire.

This Research Topic aims at highlighting recent progress in remote sensing methodologies for studying forest fires, burned areas, damage, emissions, soil erosion, deforestation and land cover change, vegetation regeneration, also contributing to forest fire modeling and identification of areas at highest risk.

We solicit contributions describing innovative remote sensing-based approaches, data processing techniques and modelling tools, to improve understanding of fire and to support operational applications. In addition, we encourage contributions on the integration of remote sensing data and data collected on field to confirm and improve the existing models. We invite researchers to contribute Original Research articles as well as Review articles.

Potential topics include but are not limited to the following:

• Multispectral (e.g. Sentinel-2, Landsat-8 OLI) and Hyperspectral (e.g. PRISMA) data processing;
• Synthetic Aperture Radar (SAR) images processing (e.g., Cosmo-Skymed, Sentinel-1, ALOS PALSAR);
• SAR polarimetry;

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
