Top Climate Solutions in Agriculture and Forestry: Proven Strategies for a Sustainable Future

The OECD’s report titled “Mitigating Climate Change in the Agriculture, Forestry, and Other Land Use (AFOLU) Sectors” offers important insights into how effective policies can reduce greenhouse gas (GHG) emissions in these areas. Authored by Lauren Lee and Ada Ignaciuk, the report reviews around 190 studies on policies from OECD and G20 countries.

Key Findings

One standout finding is the impactful role of forest protection. Policies that halt the destruction of natural carbon sinks, like forests and peatlands, showed the ability to cut emissions by up to 86 tonnes of CO₂-equivalent per hectare each year. This highlights how vital it is to protect these ecosystems in our fight against climate change.

The effectiveness of these policies can vary based on location, governance, and enforcement. Studies from Brazil, Indonesia, and Mexico indicate that targeted policies yield stronger emission reductions, especially in areas at high risk for deforestation.

The Role of Technology

Technological solutions, such as advanced biofuels and carbon capture technologies, can also significantly reduce emissions—by around 30 tonnes of CO₂-equivalent per hectare. However, many of these options face high upfront costs and technical complexities that hinder their widespread adoption. Government investment in research and development has proven beneficial, reducing emissions by an average of 28 tonnes of CO₂-equivalent per hectare by enhancing productivity and developing sustainable practices.

Subsidies: An Expected Tool

Subsidies remain prevalent in AFOLU policies but are often only modestly effective, averaging about 5.3 tonnes of CO₂-equivalent reduction per hectare. Some subsidy programs can lead to positive results, particularly for afforestation and methane reduction. Yet, others have shown mixed impacts due to outdated or misaligned incentives. The concept of "subsidy lock-in," where ineffective programs persist due to political inertia, complicates progress.

Carbon Pricing: Potential vs. Practice

Carbon pricing, a theoretically effective tool for reducing emissions, is still not widely implemented. Despite showing potential reductions of about 6 tonnes of CO₂-equivalent per hectare, real-world application faces hurdles like political resistance and measurement challenges. Nonetheless, when managed properly, carbon taxes can be more cost-effective than subsidies, especially if the revenues fund support for farmers affected by these changes.

Ongoing Challenges and Mixed Outcomes

Despite some promising findings, the report reflects a cautious view of carbon trading schemes and voluntary agreements in the AFOLU sector. Questions around transparency and effectiveness linger, often resulting in mixed results across different programs. For example, nearly 40% of evaluations of trading systems yielded inconclusive findings.

Voluntary agreements can be beneficial if paired with strict monitoring and enforcement, helping to enhance political acceptability and engage a broader range of stakeholders.

Conclusion

The OECD emphasizes that no single policy will resolve climate challenges in agriculture and land use. Instead, we need a balanced mix of targeted approaches. Policymakers are encouraged to explore comprehensive strategies that address the entire food system—from production to consumption and waste—if we aim for meaningful progress toward net-zero emissions.
