Sustainable farming has never been more important. Farmers today face the dual challenge of feeding a growing population and protecting their land’s longevity.
Crucially, true sustainability must also be economic; the goal is to enhance environmental health without compromising farm income. To support this, we’ve compiled a series of Farmer’s Inside Track articles focused on practical, profitable strategies for the future-focused producer.
Whether you grow crops or raise livestock, every farmer shares a responsibility: to produce food without degrading the land, water, and ecosystems that sustain agriculture. This is particularly important in South Africa, where environmental challenges are closely linked to farming.
According to the department of forestry, fisheries, and the environment and the United Nations Environment Programme (UNEP), about 91% of South Africa is dryland, making it vulnerable to desertification. Land degradation affects food security, livelihoods, biodiversity, and community resilience.
Around 80% of the country’s land is used for agriculture, but only 11% (12.76 million hectares) is truly arable. Of this, 82% is commercial farmland, with the majority (69%) dedicated to grazing.

Several frameworks can guide farmers toward sustainable practices, including agroecology, conservation agriculture, and regenerative agriculture. While these approaches share some principles, each has distinct features, and they can be applied concurrently. Experts break down these differences, helping you determine which framework, or combination of frameworks, best fits your farm.
Diversifying income through agroecology
Agricultural Research Council (ARC) economist Joseph Kau explores how ecological frameworks can unlock new revenue streams for the modern farmer. By prioritising climate-adapted indigenous crops, producers can tap into high-value niche markets, improving financial accessibility while building a more resilient and sustainable production system.
Conservation agriculture in livestock management
Rangeland scientist Patrick Rakau advocates for conservation agriculture, a system built on minimal soil disturbance, permanent soil cover, and plant diversification. These practices protect the land and ensure year-round feed availability, providing a critical safety net during the lean winter and early spring months.
Unlocking revenue via regenerative agriculture
Carbon credit expert Matthew Kensett explains how regenerative land management does more than just restore the earth. By actively sequestering carbon dioxide as soil organic carbon, farmers can transform their environmental stewardship into a tangible new income stream.
Soil as the foundation
Whether you are raising crops or managing livestock on pasture, everything begins with the soil. According to the Food and Agriculture Organisation (FAO), soil degradation – the decline of the soil’s capacity to support its ecosystem – is a threat every producer must guard against.
In this article, crop scientist and farmer Dikgang Molebatsi breaks down why maintaining soil organic matter is the single most critical step in building a resilient, long-term farming operation.
Soil aggregates & microbes
In this article, ARC crop scientist Dr Buhlebelive Mndzebele explores the vital synergy between soil aggregates and microbial life in driving productivity. The saying ‘take care of your soil, and it will take care of you’ rings true here, highlighting how microorganisms act as the biological glue for healthy soil structure.
By keeping these ‘tiny workers’ thriving, farmers can significantly boost soil aggregation, enhance water retention, and ultimately produce higher-yielding, more resilient crops.
