Greenhouse gas saving potentials in agriculture
Agriculture is responsible for a good part of human-caused greenhouse gas production. Reducing the amount of CO2, CH4 and N2O produced in agriculture will be crucial for climate change mitigation efforts (see also Wollenberg et al., Global Change Biology (2016) 22, 3859–3864). To identify production areas and practices of particular potential for reduction, Carlson and colleagues set up a global inventory of food production intensity (how much greenhouse gas is produced per kilokalorie food?). They reached such an inventory by combining high-resolution satellite data with models describing greenhouse gas and food production by various agricultural practices. Their approach is exclusively focused on crop production, excluding for example emissions from livestock production, from deforestation or from fertilizer production.
