About this Research Topic

Background

From the launch of Landsat I in 1972 until today, satellites have captured critical, continuous information about the Earth’s natural resources and the changing human footprint, particularly regarding agriculture. With increasing launches of Earth-observing satellites, data policies allowing broader access to moderate and high-resolution Earth Observation (EO) data, and rapid advances in cloud and high-performance computing, possibilities have blossomed for extracting and applying insights from these data to humanity’s most urgent problems: food security, climate change and peoples’ resilience to shocks and stresses, including drought, flood, conflict, and others. However, challenges to efficient uptake and application of EO data persist at every level, from farmer’s plots to ministries of agriculture and international fora. One challenge is the extent to which access to and use of EO data and derived products is democratized. Another relates to communication inefficiencies between technical experts who work with these data and the decision-makers -- from farmers to politicians -- who could benefit from them. Others relate to technical challenges brought about by the lack of ground-truthing and validation data for training models as a result of limited access to fields, decaying monitoring infrastructure, and privacy concerns around these data, limiting researchers’ ability to develop robust, widely applicable models across cropping systems at scale. This Research Topic seeks to demonstrate the extent to which the field is making revolutionary strides in applying EO data to the world’s most pressing problems while leveraging and building capacities of all stakeholders, from village to globe.

This Research Topic invites papers that:

- Present the latest applications of EO data for addressing aspects of food security, hunger, and human and environmental resilience (e.g., land cover/land use for agriculture and biodiverse environments, crop classification, yield estimation, water both marine and freshwater, climate variability and change, markets, agricultural insurance, land tenure, soils, etc.);

- Describe how possibilities for using EO data to address these urgent problems -- defined locally, regionally and globally -- have increased exponentially in recent years, while efforts to build human capacities to use these data have not kept pace, creating a bottleneck to progress that underscores the practical as well as ethical need for EO data democratization. What are examples of success in these regards? What challenges do we face to increasing EO data democratization and how might they be overcome? What could an EO data-democratized future look like? How much faster could we address these urgent problems if there was more capacity to use these data, and more opportunity for all stakeholders to engage in solution-finding and decision-making processes?

- Describe significant EO-enabled possibilities on the horizon, e.g., the development of a global agricultural field boundaries database, global agricultural land use change, or shared ground-truthing data sets; and

- Illuminate and prioritize challenges to maximizing the possibilities of EO data for improving food security and agriculture and how they might be addressed.

Authors should address the extent to which research has been grounded in local realities; how the continuum of stakeholders has been engaged in producing, translating, and applying the findings of this scientific endeavor; what challenges to cross-stakeholder communication and collaboration exist; and what examples of successful cross-stakeholder engagement exist or are envisioned for the future.

Keywords: Earth observations, Food security, Climate change, Climate shocks, EO data, Environmental resilience, Land use, Global agriculture, Land use change, Data policy, Human resilience, Environmental change impacts

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.
