Modelling Forest Resilience under Climate Change: Integrating Hydrology and Carbon Sequestration through Process-Based and Data-Driven Approaches

About this Research Topic

Background

Forests are key regulators of the Earth’s carbon and water cycles, yet their resilience is increasingly challenged by global warming, recurrent heatwaves, and prolonged water scarcity. These climatic extremes alter evapotranspiration, soil moisture dynamics, and carbon exchange processes, ultimately threatening the capacity of forests and mangroves to function as carbon sinks. Understanding how hydrological variability drives carbon sequestration—and how feedbacks emerge under a changing climate—is essential to keeping ecosystems within safe operating limits of the Planetary Boundaries framework.

This special collection invites contributions that explore measurement techniques and modelling frameworks linking hydrology, carbon fluxes, and vegetation resilience across different biomes—from boreal and temperate to tropical and subtropical ecosystems. Process-based hydrological models such as the GR family, HBV, Topmodel, and SWAT+ offer valuable mechanistic insights into water balance and storage dynamics, while data-driven and hybrid approaches—including conditional probability distributions, regression trees, artificial neural networks, and long short-term memory (LSTM) networks—enable the discovery of complex, nonlinear relationships from extensive environmental datasets.

The convergence of big data, flux tower networks, and remote-sensing observations now allows for global-scale assessments of forest–atmosphere interactions, enabling new ways to detect causal-effect relationships between hydrological stress and carbon exchange. However, several open questions remain: How can we reconcile process-based understanding with data-driven inference to better represent drought and heatwave impacts? What defines the limits of forest resilience under compounded water and temperature stress? Can integrated models capture early-warning indicators of tipping points in carbon and water cycling?

By combining diverse modelling and measuring philosophies and leveraging large environmental datasets, this special issue aims to advance the predictive understanding of coupled hydrological–carbon processes under climate change. Contributions addressing cross-scale interactions, feedback mechanisms, and the role of water availability in maintaining vegetation resilience are particularly encouraged. Collectively, these studies will help refine the tools needed to anticipate and manage ecosystem responses within the rapidly shifting boundaries of the Earth system.

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.
