About this Research Topic

Background

Edible wild plants and fungi have been used by human communities since historical times and are some of the first cropped species. In developed countries, the practice of using wild edible species has largely been abandoned, but there is currently an increasing trend to revalue them. Conversely, in less developed regions, the harvesting and use of wild plants and mushrooms remain a current practice, and a number of species are also marketed and have large socio-economic importance.

In a time marked by climate change, overexploitation of natural resources, increasing global population, and food insecurity, knowledge of the potential availability of natural resources, their valorization, and sustainable use are important at all levels.

Thus, research on the theme of edible wild species and fungi can make an important contribution to the knowledge of the potential and valorization of these useful species, to food security, and to income generation through the exploration of non-wood forest products.

Useful plants and fungi have the potential to satisfy the basic needs of populations for food, medicine, and phytochemicals, among other uses, and possibly represent the largest ecosystem provision service used by rural communities. Hundreds of lesser-known indigenous species gathered from the wild contribute to food security and play vital roles in human nutrition, particularly in rural areas.

A large diversity of plants and fungi are used by rural communities, namely fruits, leaves, and tubers from herbs, shrubs, vines, and trees, as well as mushrooms. Several species are undergoing domestication or are protected by locals, such as some species of fruiting trees and palms.

Some wild and semi-cultivated species are traded in local and city markets but only a few of them have acquired economic importance. Many of these plants are important components in agroforestry systems and must be used in the sustainable intensification of crop production.

Many traditional foods have been associated with functional properties that can prevent or treat a wide variety of ailments, have great potential to fight malnutrition and deficiencies, and also help to prevent health conditions. The chemical exploration of matrices from plants and fungi for their nutritional and functional properties and the identification of molecules responsible for reported effects is a matter of increasing research attention.

However, wild plants and fungi have received little research attention or extension activities, remaining largely neglected by mainstream international science. Also, the taxonomy of species, cultivars, and landraces of edible plants and fungi is often uncertain and there is a requirement for clear identification of taxa with scientific names, local names, and voucher samples.

This Research Topic intends to gather contributions to enlighten the present and potential importance of wild edible plants and fungi as a natural resource to be explored, valued, and preserved.

Contributions on a wide range of subjects related to the role of wild plant and mushroom species to food security are welcome for submission to this Research Topic, such as:
• Functional properties of wild edible species;
• Chemical composition: nutrients, beneficial bioactive non-nutrients, and toxins
• Conservation status of intensively harvested species;
• Crop wild relatives for food security;
• Suitable species for agroforestry systems and domestication;
• Food processing systems for wild edible species;
• Market chains and economical importance from local to national scales;

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.
