Background

Agri-food systems have been a major driving force for economic development in many sub-Saharan Africa (SSA). They provide employment opportunities for many people directly and indirectly at different nodes of the food system. Agri-food systems also provide raw materials for many industries, thereby facilitating the development of the industrial sector, and contributing to addressing malnutrition and food insecurity by providing people with nutritious food. This evidence suggests that the ability of African countries to achieve Sustainable Development Goals (SDGs) depends greatly on the prevailing agri-food systems. However, current agri-food systems are not resilient or sustainable enough to supply countries with sufficient and nutritious food to meet the ever-increasing demand for it. This situation is expected to be worsened by a harsher climate in the future, as projections indicate that food systems may be increasingly exposed to temperature extremes, and arid, and semi-arid conditions in the near future, which could result in significant production losses caused by moisture stress.

Climate change and variability present a great challenge for the 21st-century food systems in SSA. Evidence shows that poverty and food insecurity are more prevalent in SSA, particularly in areas where climate change and variability are more pronounced, and further made worse by conflicts and inflation.
Therefore, it is important to build resilient and sustainable food systems in Africa by strategically focusing on strengthening the adaptive capacity of smallholder producers to sustainably increase farm productivity and food supply. Also, ensuring rural farmers’ access to and usage of climate information services is crucial in stimulating adaptation measures. Access to relevant climate information could guide farmers in their production and marketing related decisions by informing their crop choice, technology adoption, input use (intensification), and commercialization decisions to enhance yields and curb the potential adverse effects of bad weather conditions.
In Volume I of this collection, nine papers have explored this issue focusing on thematic areas that analysed the nexus between climate change, variability, and sustainable food systems in Sub-Saharan Africa and Asia. The most important outcome is the urgency to develop effective strategies to enable policymakers to make the necessary transformation to build a climate-resilient food system. These strategies may include the promotion of carbon smart technologies, especially conservation agriculture, and agroforestry, valorising the local knowledge on agroforestry practices to make them more accessible to development practitioners, and the promotion of climate resilient crop varieties. As a last pivotal point, there is the need to develop and implement an appropriate decision framework to reduce climate risks and strengthen resilience in the aquaculture system by conducting environmental risk assessments before applying major agricultural development policies, in order to minimize unintended negative impacts.

Even if the COVID-19 pandemic has been officially overcome, new challenges are affecting food security, and climate change impacts are getting more evident and severe. Thus, with Volume II of this collection authors are invited to submit original empirical research to suggest further strategies to achieve a climate-resilient and sustainable food system. Submissions may cover the following themes (but are not limited to):

1. The impact of climate change or variability on sustainable farm productivity and food security;
2. The role of adaptation strategies to climate change in ensuring sustainable rural farm productivity food security, and resilience;
3. Vulnerability to climate change and the sustainable food and nutrition security nexus;
4. Climate variability, crop diversification, and sustainable food and child nutrition security
5. Understanding drivers of farmers’ access to climate information service, and its impact on welfare and food security;
6. The contribution of climate information services to the adoption of adaptation strategies;
7. The impact of climate change on the seed industry and its implications for farmers' access to quality seed for important food crops in SSA and Asia;
8. Climate change impacts on agriculture and adaptation measures using econometrics, crop models, and bioeconomic models under current and potential future climatic conditions;
9. General adaptive measures to reduce the potential adverse effects of harsher future climate in crop-livestock systems in specific contexts and locations.

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • 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.
