In New Zealand there is a shared analysis and understanding between business and government in the development of agricultural knowledge systems. Primary production underpins the economy. A key driver of New Zealand's international competitiveness is research and technology for agriculture. This section presents case studies to illustrate the private sector's experience in working with government to develop these knowledge systems to meet global challenges at the nexus of food security and climate change. This experience extends from developing near-science to near-market knowledge. The role of the private sector varies in this range to reflect, in part, the different risks, timeframe, competencies and value relevant to business.
