Sustainable and regenerative agriculture imply very different standards of land stewardship. Sustainable agriculture allows a farmer to remain on the land, while regenerative farming requires deeper stewardship that leaves soil in a measurably improved condition.
Across Africa, adoption remains uneven, shaped less by ideology than by economics, land tenure, and access to finance.
These structural realities become visible when comparing agricultural systems across the continent. In South Africa, around 30 000 commercial farmers operate within a system where secure land tenure allows land to be used as collateral, unlocking access to production finance.
North of the Limpopo River, that model is far less common, and many farmers cultivate smaller plots without title and achieve significantly lower yields because access to finance, mechanisation, and technology remains constrained.
Even where finance is available, the transition to regenerative farming rarely happens overnight. It is one in which reducing fertiliser use, restoring soil biology, and adopting minimum tillage practices can initially suppress yields. For farmers operating on thin margins, a two- to three-year dip in production threatens cash flow and debt servicing.
Adoption remains uneven
Over time, however, the economics begin to change, as healthier soils retain moisture more effectively, fertiliser use declines, and biological pest control replaces chemical inputs. The real advantage is stability, not chasing the highest possible yield.
This shift challenges traditional agricultural credit models that prioritise immediate output over resilience. Farmers using fewer inputs are less exposed to cost volatility, while soils with stronger moisture retention allow planting when neighbouring fields remain fallow.
Market forces are also accelerating the transition, as export markets increasingly require evidence of environmental performance. South Africa’s citrus industry experienced this pressure years ago when shipments were rejected in Europe due to pest concerns, and similar expectations are now emerging across macadamias, table grapes and wine. Sustainability is shifting from a marketing label to a condition of market access and premium pricing.
Overcoming barriers
Even as these market pressures increase, adoption remains constrained by cultural barriers in a sector where farming knowledge passes from generation to generation and practices refined over decades carry authority. Convincing a fourth-generation farmer to abandon deep ripping or heavy fertiliser use requires visible results, not theoretical assurance, and peer influence often proves more persuasive than policy.
Across much of Africa, the constraints are more fundamental, as smallholder farmers frequently depend on government-supplied seed and fertiliser that arrive late or are poorly suited to local conditions.
One practical response is the hub-and-spoke model, where a commercial anchor such as a mill, crushing facility, or large farm supplies surrounding farmers with quality seed, appropriate fertiliser, mechanisation, technical support, and a guaranteed offtake. Under such systems, farmers who previously struggled to harvest 1t of maize per hectare can achieve significantly higher yields.
Scaling sustainability through finance, investment
Realising these gains at scale requires finance that supports the transition instead of penalising it, particularly where early-stage yield reductions create carry-over debt that blended finance structures can absorb through concessional funding and subordinated capital.
Encouragingly, investor appetite for sustainable agriculture is already evident. Nedbank’s R2 billion sustainability bond, which included climate-smart agriculture as a use of proceeds, was oversubscribed by a factor of two, demonstrating that capital is available when credible frameworks are in place.
Maintaining that credibility will depend on independent monitoring of soil carbon, water use, and input reductions so that regenerative agriculture remains a measurable practice rather than a label.
Africa is often described as the world’s future food basket, but that future depends not only on output but on how that output is produced. Gulf states are investing heavily in African agriculture to secure food supplies, highlighting the continent’s strategic importance, yet without sustainable practices, productivity gains may prove short-lived as soils degrade and yields decline.
The transition will take time, because farmers adopt innovations only when the economics work, markets demand them, and the land responds. Regenerative agriculture is moving in that direction, driven by markets, economics, and the realities of climate.
Ultimately, farmers will adopt regenerative practices when the numbers make sense.
