However, for Africa to get the full benefit of these environmental superfoods, the continent needs coordinated efforts to optimise, scale up and mainstream these robust and valuable crops.

More and novel, de-risking investment models into genetic improvement research programmes and inclusive governance systems would be one place to start. Although root crops are traditionally difficult to breed, recent scientific breakthroughs have made it possible to produce varieties that are even more drought tolerant, heat resistant and tolerant of increased salinity.

Genomics-assisted breeding has further accelerated this progress, which is fundamental for delivering next generation varieties that are both climate-smart and more nutritious. Hardier and more nutritional root crops would benefit populations in both rural areas where they are grown, and urban areas, where it can be more challenging to supply fresh, healthy and perishable produce.

Developing Africa’s capacity to use agricultural science and research to improve the qualities of root crops according to regional and local differences also requires greater scientific cooperation. A regional roots, tubers and bananas partnership is leading the way, encompassing national research programs, CGIAR crop research centers and international science partners.

Climate variability across Africa means the impact on roots and related crops will differ country by country. For instance, some evidence suggests future climates may impact potato production in Malawi, Tanzania, and Uganda, but would favour potato systems in Burundi and Rwanda.

The continent would therefore benefit from more integrated and cross-border breeding programmes that pool resources and brain power for efficiency, while simultaneously creating the capacity needed to respond to the specific needs of different contexts.

Finally, and equally relevant, the latest and most suitable varieties must get to the farmers who need them through efficient and accessible seed delivery systems.

In Africa, improved varieties of most crops have an adoption ceiling of about 40 per cent, which means the majority of farmers are using seeds and planting material that have not been optimised for today’s conditions. The average age of a variety in farmers’ fields is often 10 years or more, leaving farmers and food supply chains missing out on a decade of ever-increasing agricultural advancements.

Finding and developing the most effective ways to reach farmers, whether through informal channels, cooperatives, government initiatives or non-profits, is vital to accelerate the adoption of new, climate-smart varieties.

The recent Africa Climate Summit demonstrated the power of a unified voice to address the common challenges facing the entire continent. Yet it also recognised the country-level nuances inherent in dealing with an emergency like the climate crisis.

When it comes to climate-proofing food security, local staple crops such as roots and tubers offer the greatest potential, and with more investment and collaboration, they can become multi-purpose solutions that meet Africa’s needs. The Green Revolution that transformed global cereal production is yet to happen for roots, tubers, and bananas. Harnessing advancements in science, environmental lessons, and regional political leadership, the moment is at hand for these crops to put Africa on a track for a food-secure future.
