By Corinna Byrne, from Fleeing Vesuvius. Farming and other land-based activities could do a lot to mitigate global warming. Ireland needs new policies to get its land to absorb CO2 rather than release it. The large amounts of carbon locked up in the country’s peatlands must be safeguarded and damaged bogs restored so that they can sequester carbon again. In addition, the use of biochar could reduce methane and nitrous oxide emissions and build up the fertility and carbon content of the soil.
