Tswalu has become the first privately protected area in southern Africa to earn carbon credits from wildlife management interventions, offering a model where conservation pays for itself through verified soil-carbon removals. The 291,000-acre reserve in South Africa’s Northern Cape achieved this through credits certified by Credible Carbon, backed by actual soil samples from 59 monitoring stations that document reduced grazing pressure and restored grass cover.

The numbers demonstrate measurable environmental recovery: grass cover rose from 38% in 2017 to 57% in 2022. Credible Carbon certified 34,471 verified carbon units from the first vintage, with 6,179 used internally to offset Tswalu’s operational emissions and 5,200 sold to buyers including 4,000 credits to Nutec Digital Ink and 1,200 to the Earthshot Prize.

## What Happened at Tswalu: From Degraded Farms to Carbon Sink

Tswalu spans almost 460 square miles through the consolidation of over 50 former livestock farms, moving from intensive agricultural use to conservative stocking rates with wildlife-driven grazing patterns. This management change allows grasslands to recover naturally, dramatically increasing the land’s capacity to sequester carbon in soil through deeper root systems and reduced grazing pressure.

The project’s soil-carbon monitoring relies on a network of 59 soil carbon stations distributed across the reserve. Rather than theoretical projections, the system uses actual soil samples to verify carbon storage, subjecting results to Credible Carbon’s audit process with UN-approved methodologies. This approach addresses [growing market demand for verified carbon removal credits](https://www.ecosystemmarketplace.com/publications/2024-state-of-the-voluntary-carbon-markets-sovcm/), which commanded a 381% price premium over emissions reduction credits in 2024.

## Why This Credit Is Different: Removals, Not Just Avoided Emissions

The distinction between carbon avoidance and removal credits has become crucial as voluntary carbon markets mature. Avoidance credits prevent future emissions, whilst removal credits like Tswalu’s actively draw CO2 from the atmosphere and store it in soil. The project stores carbon through rehabilitated grasslands where reduced grazing allows deeper root growth and enhanced soil organic matter.

Soil sampling provides the verification backbone for removal claims. Independent audits measure actual carbon accumulation between monitoring periods, with a second vintage due in Q4 2025 following a follow-up audit. The project timeline extends to 2039 with an expected total issuance of 274,534 credits, released every three years following re-measurement and third-party auditing.

## Ecological Results and Verification

The biological recovery extends beyond grass cover improvements. The reserve now supports 70 dung beetle species, 75 mammal species and 24 protected plant species, indicating broader recovery from the consolidation of degraded agricultural land. Soil carbon data shows significant sequestration between the first and second audit periods, validating the management approach.

Credible Carbon certification requires independent auditors using standardised methodologies to verify soil carbon accumulation. The audit process examines sampling protocols, quality control measures and site-level data from the 59 monitoring stations. This level of scrutiny addresses [industry concerns about soil carbon credit integrity](https://agfundernews.com/perennial-secures-verra-green-light-for-digital-soil-mapping-tool-a-quantum-leap-forward-in-soil-carbon-quantification) that have emerged as the market expands.

## Money, Buyers and Local Returns

Revenue flows demonstrate the project’s commercial viability. After using 6,179 credits to offset Tswalu’s operational emissions from 2019 to present, the remaining credits entered commercial markets. Nutec Digital Ink purchased 4,000 credits whilst the Earthshot Prize acquired 1,200, though specific pricing remains undisclosed.

Carbon revenue channels back into conservation operations and community welfare, including accommodation with utilities, free healthcare access and educational opportunities. The employment structure creates [nature-based jobs](https://www.sovereignmagazine.com/article/why-one-in-five-planted-trees-die-before-they-can-help-britain-reach-net-zero-and-how-rhizoco) that reportedly exceed previous agricultural employment levels in the Northern Cape region, though detailed workforce data and revenue allocation governance require further scrutiny.

## Questions That Need Answers

Several critical questions warrant investigation for evaluating the model’s broader applicability. Baseline establishment across 50+ consolidated farms raises additionality concerns about whether carbon improvements represent genuine additional sequestration or natural recovery that would occur regardless.

Permanence risks emerge from the 21-year project timeline, particularly regarding future grazing pressure, drought impacts, fire events and potential reversals. The project’s fenced nature provides some protection, but climate variability in semi-arid rangelands poses ongoing risks to soil carbon stability.

Price transparency remains limited, making it difficult to assess revenue potential for similar projects. Without disclosed credit prices or detailed revenue allocation agreements, the economic model’s replicability remains unclear. Independent verification of employment figures and community benefit claims would strengthen the project’s social impact narrative.

## Local Livelihoods: The Human Story

The shift from agricultural to conservation land use creates different employment patterns. Management claims that nature-based tourism and conservation jobs exceed previous agricultural employment, supported by provision of accommodation, utilities and healthcare access. However, detailed employment comparisons, wage scales and community impact assessments would provide clearer evidence of socio-economic benefits.

Revenue from carbon sales supports conservation operations whilst funding community services, though the governance structure controlling these allocations requires clarification. The model’s success depends partly on transparent revenue management and demonstrated community benefits that extend beyond abstract claims to measurable improvements in local livelihoods.

## Replicability and Limits Across Southern Africa

Tswalu’s success relies on specific conditions that may limit broader replication: large consolidated landholding, effective fencing, technical expertise and substantial upfront investment. The model works well for private reserves with secure tenure and resources for long-term monitoring, but faces challenges in communal lands, unfenced rangelands and fragmented ownership structures.

Matthew Child of Rewild Capital emphasises the broader potential: ‘The Tswalu project serves as a model for how wildlife and rewilding can be utilised to restore functioning, creating a new approach for other protected areas – and potential protected areas – in South Africa and beyond. This scalable approach offers hope for changing how conservation is funded across southern Africa and beyond. If the Tswalu model is adopted by more landowners and communities, it could potentially reshape how conservation is funded.’

Success elsewhere would require solid baseline data, long-term protection guarantees, accessible monitoring systems and third-party auditing capacity. [Research from South Africa’s Eastern Cape](https://pubmed.ncbi.nlm.nih.gov/26059244/) demonstrates that livestock exclusion followed by sustainable light grazing can improve soil carbon sequestration, supporting the biological foundation of the Tswalu approach.

The model offers particular promise for other private reserves across southern Africa, where [studies in semi-arid Karoo regions](https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2020.590665/full) show how grazing intensity affects vegetation and soil carbon storage. However, replication requires addressing governance challenges, technical capacity and long-term funding for monitoring and verification.

As voluntary carbon markets face increased scrutiny over credit quality and [audit-ready emissions data](https://www.sovereignmagazine.com/article/carbon-management-why-audit-ready-emissions-data-is-becoming-a-boardroom-priority), projects like Tswalu demonstrate how verified soil-carbon sequestration can provide credible removal credits. The approach aligns with growing interest in [biologically based carbon solutions](https://www.sovereignmagazine.com/article/carbon-capture-agriculture-market-signals-shift-to-biologically-based-solutions) that offer measurable environmental benefits alongside commercial returns.

Tswalu offers a rare case where wildlife management generated verifiable soil-carbon removals with direct sales and documented local benefits. The model’s wider value will depend on transparent data sharing, clear revenue governance and independent scrutiny as more vintages are issued. The next audit and vintage issuance expected in Q4 2025 provides a near-term milestone for assessing the project’s continued effectiveness and commercial viability.
