About this Research Topic

Background

Agronomy, as the science and practice of crop production, is the thread that ties and underpins the SDGs of Hunger, Health, Water, Work, Consumption, Climate and Land – in short seven of the SDGs and, thus more than any other sector. As a science, agronomy is defined as the study of the interactions between genotype, environment and management (GxExM) and, as a practice, as the implementation of agronomic knowledge into growing food. Knowledge can come from theories, experience and experiments, but best following the interaction of these elements. Agronomy is concerned with both producing food but also its nutritional quality. The social aspect of agronomy is evidenced in the gender balance between agronomic scientists, advisors and practitioners and farmers.

Agronomists work at scales ranging from square metres to the hectares of a field; agronomy’s biological scales go from individual plant organs to plant populations via the individual plant. Complex agronomy covers crop communities; the temporal scale ranges from a day to a year. Fields are the meaningful sites for integrating reductionist plant sciences.

Agronomists need to have a broad and integrated scientific knowledge; this includes soil and earth sciences chemistry, biology, crop genetics and ecology and social sciences, reflecting GxExM. Understanding the myriad of interrelationships between biotic and abiotic ecosystem components means that agronomy needs to focus on ways to predict and project the GxExM of food production by using simulation models and other tools, such as statistical analyses. Many of these tools and techniques originated in crop science and agronomy. In summary, agronomy tries to improve the systems that humans use to produce food, feed, fuel, and fibre by understanding the interactions, and thus integration, of crop genotype, environment and management.

In the context of the UN SDGs, agronomy and hunger have a clear interaction; health includes the provision of nutritious food, agronomy uses large quantities of water; work in agronomy highlights gender differences; food consumption and waste are as important in food security as food production; climate and weather have huge effects on food production and land is the essential planetary resource for producing food.

As part of an innovative collection showcasing agronomy in the context of the SDGs, this Research Topic will focus on Sustainable Development Goal 2: Zero Hunger.
Zero hunger encompasses combating all forms of malnutrition, globally. This includes combating the “double burden”, which includes inadequacy (i.e. malnutrition and all its forms-stunting) and excess (obesity). As the global population is projected to reach 9 billion by mid-century, it is imperative that differences in access to sufficient food of nutritious quality are addressed. Agronomy has a key role to play in food security and nutrition. Evidence shows the key contribution of soil management to crop nutrition and human health with crops grown on well-managed plots (i.e. with organic matter inputs) yielding crops with higher micronutrient concentration compared to crops grown on poorer soils.
Biofortification, an approach encompassing the production of micronutrient biofortified crops and the use of micronutrient-based fertilizers are cost-effective approaches which contributes to the alleviation of deficiencies in the farming family. Research on biofortification is ongoing, however, collaborative research is key to meeting SDG2.

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 they fall 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.
