About this Research Topic

Background

Climate change and the resulting extreme weather events, such as heatwaves and drought, are currently posing a threat to agricultural production in certain regions of the world, with their frequency gradually increasing. It seems that disasters come earlier and, in more forms, than people predicted. Although elevated atmospheric CO2 concentrations (eCO2), acting as a form of carbon fertilizer, theoretically enhance crop photosynthesis and promote food production, they also serve as a driving force for global warming, thereby accelerating climate change and the frequency of extreme weather events.

Despite global governmental efforts, the amount of CO2 in the atmosphere continued to rise faster than natural processes could absorb. In addition, the adverse changes in other environmental factors, such as increased ozone concentration, have universally affected ecosystems worldwide and significantly influenced agricultural productivity and food security. It is essential to study how crops respond to these climate factors and develop adaptive strategies in order to ensure a sustainable food supply.

In spite of growing awareness of the impacts of climate change on agriculture, there remains a critical need to understand the nuanced responses of crops to eCO2 levels, increased temperatures, higher ozone concentrations, and more frequent drought conditions. Current knowledge often lacks comprehensive insights into the interactive effects of these factors on crop growth, yield, grain quality, and the paddy diseases, insect pests and weeds. Moreover, there is a lack of new effective coping measures, including breeding, cultivation, and biocollaborative approaches.

To address this gap, this Research Topic aims to systematically investigate how various crops adapt to changing climatic conditions, focusing on the mechanisms underlying their responses. By elucidating these mechanisms and identifying effective adaptation strategies, the goal is to enhance agricultural resilience and ensure sustainable food supplies amidst ongoing climate shifts.

Research papers are welcomed on the following themes, but not limited to:

• Impact of eCO2 on Crop Performance: Investigate how eCO2 concentrations affect crop photosynthesis, growth, yield, and grain quality.

• Temperature Effects on Crop Development: Analyze the consequences of rising temperatures on crop phenology, yield, and nutritional value.

• Ozone Concentration Influence: Examine the role of increased atmospheric ozone levels on crop health, productivity, and stress resistance.

• Drought Stress and Water Management: Address the challenges posed by water scarcity and evaluate drought-resistant breeding and irrigation techniques.

• Interactive Effects of Multiple Climatic Factors: Study the combined impacts of eCO2, temperature, ozone, and water availability on crop systems.

• Adaptive Strategies and Mechanisms: Explore effective measures, including breeding, cultivation practices, and biological interventions, to mitigate the adverse effects of climate change on agriculture.

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?
