Feed back and Feed-Forward Interactions between Climate Change and Grassland-Based Agriculture

This paper explores the possibility of identifying land management strategies for economically productive agricultural grassland in temperate regions that enable carbon sequestration as well as reductions in the trace greenhouse gases nitrous oxide and methane. The best overall strategy is one that involves de-intensifying to a moderate level of nitrogen use from the highest levels. This would also be compatible with the need to comply with other constraints, such as water quality legislation. Identification of similar win-win strategies for other land-use types will require development of appropriate modelling systems together with the acquisition of field data
