The climate change challenge for managed grasslands in New Zealand
(0) Key points:1)New Zealand grassland systems were created by humans through land use changes of national proportions. This has brought many economic and social benefits, but at an increasing cost to the environment and people‐biodiversity loss, loss of ecosystems integrity, flood damage, soil loss and greenhouse emissions associated with livestock and pasture management. 2)Grassland systems will be affected by changing climate and climate variability. Farming systems will need to be adapted creating systems that are more resilient and able to withstand increased climate variability and extreme events. 3) New Zealand is introducing an emissions trading system to price carbon that seeks to drive behaviour change to reduce emissions and sequester carbon. 4) Complementary research is seeking to develop on‐farm solutions that can mitigate greenhouse gases through, rumen processes ; genomics for rumen CH４ production ; forage and plant inhibitors for diet manipulation ; animal factors ; and nitrification inhibitors. 5) The ability to respond to the climate challenge for managed grasslands lies with the people that have to implement these changes‐the farmers.
