The Centre for Food Safety is a civil society organisation from the US. They are at COP21 to highlight the under recognised opportunity to address climate change: rebuilding soil carbon. Diana explains that increasing soil carbon is a triple win because it improves food security, water security, climate security and improves biodiversity. The greater the carbon content in the soil the more water soil can hold and this is crucial in making communities more resilient. She highlights the relevance of this in California, which has had the worst drought in 500 years and only has 1% soil carbon. She tells Climate Home that today is World Soil Day and the International Year of the Soil and explains that 40% of global soils are degraded
