The extent to which agricultural growth can take place while at the same time reducing agricultural greenhouse gas (GHG) emissions is much debated. There is a widespread view, reflected in the agricultural mitigation chapter of the IPCC’s Fifth Assessment Report in 2014, that changes in food consumption patterns will be necessary if GHG emissions from global agricultural production are to fall sufficiently to help to stabilise the climate by 2050. The diet changes proposed, including a shift away from meat and dairy product consumption, would deliver emissions reductions by reducing agricultural production. Others point instead to the potential of technological advances to reconcile increased agricultural output with lower emissions, effectively allowing the decoupling of emissions growth from agricultural growth.… Read the rest
