About this Research Topic

Background

Climate change is now a tangible threat to sustainable agriculture among smallholder farmers in the developing world. Extreme variations in rainfall patterns, volume and intensity, as well as high temperatures, negatively affect crop yield leading to maize yields as low as <1.5 t/ha. The severity of the impacts of climate change is higher within the smallholder sector due to these farmers’ low adaptive capacity, which has seen poor uptake of several climate change-related initiatives. Consequently, there has been a sustained interest in the search for appropriate sustainable solutions that can be easily adopted by smallholder farmers. The production of small grain crops such as sorghum, pearl millet and finger millet offers a feasible climate change adaptation option for smallholder farmers, particularly in Africa. However, several barriers and constraints such as labour intensiveness, unavailability of markets, lack of technical and government support, food preferences and unavailability of appropriate technologies hamper production leading to low adoption by farmers.

Apart from the well-documented barriers to small grain crop production in developing countries, the greatest challenge is the production of small grains by most smallholder farmers on marginal land in the poorest portions of their fields, with minimal external inputs and management, which contributes to low yields. This practice is fuelled by the common belief that small grains can do well with minimal or no management. It is therefore necessary to promote research and dissemination of information on appropriate and sustainable small grains cropping systems that will increase productivity and achieve food security and improve resilience to climate change. There is therefore a need for more research on practices such as conservation agriculture, legume intercropping, agroforestry, organic agriculture, and improved pest, water, and nutrient management. These practices may lead to improved yields and overcome some of the barriers that prevent the adoption of small grains by smallholder farmers and hence ensure food security.

Some of the barriers preventing the wide-scale adoption of small grain crops can be overcome by improving agronomic practices through recommending appropriate cropping systems, availing improved varieties, improving post-harvest management and access to markets and improving processing methods and equipment. This Research Topic therefore focuses on research and technologies that seek to overcome barriers to the adoption of small grain crops as an adaptation to climate change among smallholder farmers. We invite original research, review, practice reviews and systematic reviews that address sustainable cropping systems that will aid the adoption of small grain crops thereby increasing smallholder farmers’ resilience to climate change. We welcome research within the following themes:

• Appropriate climate-smart agriculture-based cropping systems for small grain crops
• On-farm research on improved small grain cultivars that are compatible with smallholder cropping systems
• On-farm research on integrated crop-livestock systems for small grains
• Socio-economic drivers for small grains adoption by smallholder farmers
• Low-cost small grain crops production and processing technologies
• Climate change projections and potential impacts on small grains production

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.
