It discusses the challenges of exchanging knowledge between the science and policy communities, given their different languages and cultures, highlighting the need for greater mutual understanding of roles and responsibilities. It draws on experience in the Scottish Government of developing the government's 'Recipe for Success - Scotland's National Food and Drink Policy' through engagement with stakeholders, scientists and analysts and touches on the more complex nature of the Department for International Development's contribution to meeting the first Millennium Development Goal. It compares the need for collation and analysis of existing evidence during the development of policy, with the desirability of providing policy direction for longer-term strategic research and the challenges of connecting the policy expectations with researchable questions. The paper concludes by emphasising the need to focus research in the short-term on <i>mitigation</i> of climate change through decreasing greenhouse gas emissions associated with the production of food, while also taking an account of economic, health and broader environmental sustainability objectives. A further challenge is to communicate complexity and uncertainty in ways which enable decision-makers from the consumer to policy-makers to make informed choices. Longer-term research needs to focus on the opportunities and risks associated with <i>adapting</i> to climate change. 收起
