Summary

The biggest mitigation potential of agriculture lies in soil carbon sequestration. The most promising practices for this, such as the use of legume leys and organic fertilisers, are common to organic agriculture, thus suggesting considerable mitigation potential for this farming system. However, mitigation in agriculture needs to be assessed beyond the level of single farming practices. This is best illustrated with the issues of fertility management and animal husbandry. Optimisation of fertility management necessitates optimisation of the soil-fertiliser system as a whole and, thus, the assessment of the links between crop rotations, fertiliser types, tillage and soil carbon sequestration. Optimisation of animal husbandry requires a global view, accounting for life-cycle emissions of feed production. Feeding roughage leads to lower life-cycle emissions. Most effective, however, is a drastic reduction of the number of animals, which necessitates consideration of aspects beyond agriculture. Wider societal changes such as dietary changes to reduce meat consumption or behavioural changes to reduce wastage are necessary. Organic agriculture is well positioned to mitigate climate change in such a systemic context. However, addressing mitigation in agriculture leads to some change of thought in conventional agriculture. By acknowledging the essential role of soil carbon sequestration, for example, systemic ideas have gained increasing importance in conventional agriculture. This development should be used to move towards a global approach to sustainable systemic and multifunctional agriculture.
