Harnessing Agriculture as a Catalyst for Climate-Resilient Growth: Insights for B20 SA 2025
By Andrew Aitken, Head at RMB Ventures
As South Africa approaches the conclusion of its G20 presidency, the B20 Summit— taking place from November 18-20 in Johannesburg—presents a pivotal opportunity to elevate agriculture’s role in fostering climate-resilient economies.
Under the banner of sustainable food systems and innovation, the B20’s focus on “Sustainable Productivity Growth in Agriculture” reflects global priorities for food security amid rising climate risks.
The Sustainable Food Systems & Agriculture Task Force is driving this agenda through partnerships and innovation, echoing commitments like the Kampala Declaration, a continental commitment to agrifood transformation.
With Sub-Saharan Africa’s growth projected at 4.1% for 2025, agriculture stands as a cornerstone for inclusive, green development.
This opinion piece explores key pathways—science-led growth, circular economy practices, inclusive development, digital agriculture, and green financing—to transform farming into a catalyst for resilience, drawing on recent innovations and South African examples.
Science-led growth is empowering farmers through data-driven trials and evidence-based practices, revolutionising productivity.
Emerging precision agriculture technologies are increasingly recognised for their potential to significantly enhance crop yields and resource efficiency, particularly in climate-vulnerable regions.
Global organisations such as IFOAM – Organics International are promoting these innovations alongside organic practices to help farmers transition to sustainable agriculture, advocate for supportive policies, and raise awareness about responsible production and consumption.
Across Africa, collaborative science initiatives are accelerating innovation in agriculture, health, and technology.
The Science for Africa Foundation highlights progress in areas such as clinical research, biosecurity, and sustainable farming practices, underscoring the continent’s growing role in global scientific advancement.
AfriKelp, a South African firm, exemplifies how local scientific innovation in biostimulants—such as those derived from kelp—can contribute to global climate resilience.
Such initiatives not only mitigate climate impacts but also empower farmers optimise yields, underscoring B20’s call for innovation in climate-smart systems.
Building on science-led innovation, the next frontier is circularity—creating farming systems that minimise waste and maximise resource efficiency.
Transitioning to a circular economy in farming enhances sustainability by closing loops on waste and inputs.
In arid regions, integrated models recycle waste into feed and water solutions, strengthening food security.
Globally, the EU’s circular economy strategy—aiming for climate neutrality by 2050—champions regenerative practices that ease resource pressure on agriculture.
Across Africa, agroecosystems are adopting closed-loop models that reuse organic waste to cut environmental footprints.
South Africa’s Integrated Resource Plan supports efficient energy use in farming, indirectly enabling water reuse and energy-efficient processing systems in agriculture.
Practical steps like composting manure into fertiliser or converting food waste into soil enhancers are gaining traction, reducing hunger and emissions while aligning with B20’s call for resilient value chains.
Inclusive growth through skills, education, and community investment ensures that agricultural transitions benefit all, particularly marginalised groups.
The African Union’s call for a new social contract anchored in education and skills development further amplifies this, unlocking Africa’s potential amid youth-focused strategies.
With over a billion people employed in global agriculture, investing in human capital is not just a moral imperative—it’s a strategic lever for resilience, equity, and long-term prosperity.
Digital agriculture is reshaping food security. AI, IoT, and satellite technology enable smart farming, optimising resources for ecological transitions.
AgTech trends point to generative AI transforming data into actionable insights, while digital agronomy accelerates global adoption.
In Africa, these tools are tackling food insecurity, with precision agriculture growing three times faster than average, according to the IFPRI 2025 Global Food Policy Report.
Finally, financing the green transition demands scaled climate finance.
Agriculture needs more, with calls for $50 billion annually in adaptation funding, as outlined in the 2025 Global Landscape of Climate Finance.
The OPEC Fund’s 2025 report highlights $180 million for agriculture, urging shifts toward food systems transformation.
B20 can advocate “greening” aid for trade, aligning with Paris Agreement goals, while leveraging private finance to bridge gaps in decarbonization.
As B20 convenes, agriculture must be positioned as the engine of climate-resilient growth.
By integrating science, circularity, inclusion, digital tools, and finance, we can forge sustainable futures. South Africa’s leadership offers a blueprint—now is the time to scale it globally and deliver impact.
