Video Interview: How Can We Sequester Carbon while Growing More Food?

By Connie Kwan

Feeding the world’s seven billion people is no small task. Many farming and food distribution systems are carbon intensive. To make matters worse, climate change can exacerbate pressure on food systems by drying out previously water rich, fertile grounds. But there is a way to both sequester carbon and grow more food in one fell swoop: composting.

During the Sustainable Food Summit in San Francisco, Tobias Bandel, Managing Partner of Soil & More International, spoke about the benefits of composting. Soil is one of the biggest carbon pools on the planet with a few gigatons of carbon potential. Industrial farming methods often employ deep tillage and chemical fertilizers, which releases carbon into the air. Composting adds carbon to the soil, which improves soil structure and its water holding capacity, thereby increasing food production.  

In one project in Kenya, Bandel was called in to address the 30-40% yield drop in tea production measured in the last 10 years. The farmers were coached to apply composting methods, and the yields increased by 25% in the first year alone. A similar result was experienced in India.

Over 70% of world food production comes from small scale farms such as the ones in Kenya and India. Many are still farming using low-input sustainable methods. But this way-of-life is continually threatened by pressures to improve productivity, often resulting in the use of chemicals to create short term boosts in productivity.  Protecting these low-input sustainable farms is very important for both long-term food productivity and carbon control. Fortunately, large retail players such as Walmart are starting to migrate their farm suppliers to low-input farming methods through the work of companies like Soil & More.  And organizations such as International Federation of Organic Agriculture Movement (IFOAM) are developing soil monitoring schemes to enable this movement. With lots of hard work and a bit of luck, the world’s people can enjoy both food abundance and a lower carbon atmosphere.

Food production sustainability, poverty alleviation and more will be discussed by world leaders at the UN Rio+20 Conference on Sustainable Development.  It is happening in Brazil June 20-22, 2012.  Participate in the discussion.
