In the face of an escalating environmental crisis, the search for sustainable solutions has never been more urgent. Biochar, a powerful tool in the fight against climate change and soil degradation, has emerged as a promising technology. In May 2024, the International Biochar Initiative (IBI) partnered with ECHO Asia to deliver the Biochar Academy at the Small Farm Resource Center in Chiang Mai, Thailand. This immersive, multi-day, hands-on course aimed to equip emerging and future biochar professionals with the necessary knowledge and tools to become effective advocates, educators, and practitioners in the biochar field.

Biochar, a stable form of carbon derived from organic materials like agricultural residues, is produced through pyrolysis – a process of heating organic material in the absence of oxygen. This method not only sequesters carbon but also improves soil health, water retention, and microbial activity when used in agriculture. Its versatility extends beyond agriculture to applications in building materials, water filtration, concrete, cooking stoves, cosmetics, and energy generation, making it a key player in global sustainability efforts.
Biochar has the potential to greatly improve soil health through enhanced water retention, increased nutrient availability, and stimulation of microbial activity, which can ultimately boost crop yields and reduce reliance on chemical fertilizers, leading to cost savings over time.
Nevertheless, many biochar producers face a significant hurdle in finding suitable markets for their biochar products due to a lack of understanding among potential consumers, including farmers.
Indeed, biochar is not a one-size-fits-all solution. The type of feedstock and feedstock drying methods, production techniques, additives, and applications – both agricultural and non-agricultural – significantly impact the benefits of a particular biochar. For agricultural uses, mixing biochar with microbial material is essential to realize benefits such as water retention and improved microbial health.
In countries of the Global South like Thailand, promoting the adoption of biochar among farmers involves demonstrating its efficacy through field trials, emphasizing long-term savings on fertilizers and soil management costs, and customizing approaches to suit local soil conditions. Educating farmers about the benefits of biochar and showcasing concrete outcomes can play a key role in establishing a market for this environmentally friendly technology.
The economic landscape for farmers is complex, especially with the rise in fertilizer costs, sparked by Russia’s invasion of Ukraine in February 2022. Biochar can help reduce these costs, but it requires time and demonstration of its effectiveness to gain farmer acceptance.

The Biochar Academy, organized by the International Biochar Initiative in May 2024, aimed to equip professionals with the knowledge and tools needed to advocate for and implement biochar solutions, emphasizing its potential to address environmental challenges and promote sustainable practices.
A SWOT analysis of biochar in Southeast Asia conducted by the Academy’s participants highlighted the following key points:
- Strengths: Biochar works well with Southeast Asian soils, reduces the use of chemical fertilizers, and offers diverse feedstock options, leading to varied applications. Farmers in the region are eager for new solutions.
- Opportunities: There is abundant biomass and accessibility to small-scale biochar production. Potential energy uses, such as storing energy created during biochar production, present additional opportunities. There is also a potential market for biochar products and carbon credits, with the opportunity to scale. The carbon market industry is crucial for the development of biochar, with the material delivering over 90% of carbon credits as of 2023. This understanding is vital for developing business strategies around biochar production and leveraging carbon credits.
- Weaknesses: The benefits of biochar are poorly understood by farmers, the life cycle analysis process is complex, and there is a general lack of awareness about biochar.
- Threats: Competition with industrial agriculture, unethical and unsustainable feedstock sourcing, and a lack of transparency in biochar production and application are potential threats.
Diverse Applications of Biochar
Biochar has applications beyond agriculture, including building materials, water filtration, concrete, cooking stoves, cosmetics, and energy generation. Understanding these applications helps broaden the market and potential uses for biochar.
Participants in the Academy had diverse backgrounds and applications for biochar. Some were involved in large-scale production using coconut husks, while others were integrating biochar into existing farming practices.
Discussions in Chiang Mai highlighted the need for community input and collaboration to enhance biochar adoption. Biochar’s benefits and applications depend on various factors, including feedstock type and regional specifics. Demonstrating tangible impacts is crucial for public and institutional support.
The Academy showed local communities in Chiang Mai how to reduce agricultural waste, improve soil health, and create economic opportunities through biochar production and use. This hands-on approach underscored biochar’s potential to address environmental challenges and promote sustainable practices.
Future Outlook
Inspired by the Academy’s success, IBI plans to organize similar events in other regions, fostering a global network of biochar advocates. New research projects and practical applications are expected to emerge from collaborations initiated during the Academy.
Biochar technology plays a pivotal role in global sustainability and climate action efforts. The Biochar Academy in Chiang Mai has equipped a new generation of biochar advocates with the skills and knowledge needed to implement and promote biochar solutions worldwide. It was not just an event – it was a significant step towards a more sustainable world.
