The Soil Association has hit back at suggestions that organic farming could be worse for the environment than conventional farming methods.

Climate expert Lord John Krebs told the Oxford Farming Conference on Wednesday (7 January) that organic farming might do more damage to the environment due to increased land required and carbon released from the soil.

The fact is organic farming is, in general, less productive per hectare than conventional farming and if we want to produce more organic food we need more land to do it, which releases more carbon into the atmosphere, he said.

Lord Krebs, who advises the government on climate change policy, argued that agricultural methods, such as minimum or no tillage, could help to protect and manage soils and store carbon to prevent the release of greenhouse gases into the atmosphere.

According to the UK government, agriculture is responsible for 9% of the UKs greenhouse gas emissions, from livestock such as cows, fertilisers and soils.

The government has committed to reducing greenhouse gases (GHGs) by at least 80% by 2050.

But Lord Krebs warned agricultures proportion of GHGs could rise to 30% if no action is taken.

In his lecture, Climate Change Challenge or Opportunity, Lord Krebs also called for a smarter use of nitrogen fertiliser and said benefits from the environment could arise from the use GM crops.
