Climate change is a global challenge that requires comprehensive and cross-sectoral action, including across agrifood systems. Such action needs to be taken in full consideration of international goals and agreements, such as the 2030 Agenda for Sustainable Development and its universally agreed Sustainable Development Goals, the Rio Declaration on Environment and Development and the Paris Agreement. It also needs to be rooted in the economic, social and environmental dimensions of sustainable development. To accelerate its contribution towards the 2030 Agenda, FAO has, within its mandate and comparative advantages, developed a new Strategy on Climate Change for the next ten years. The Strategy on Climate Change echoes the recognition of the Paris Agreement of the fundamental priority of safeguarding food security and ending hunger. It presents the role of agrifood systems as part of the solution to climate change and seeks complementarities with the missions of other organizations and related agreements. The urgency to act on climate change impacts on agrifood systems has never been clearer, as indicated by the latest reports of the Intergovernmental Panel on Climate Change. Agrifood systems must become more resilient to the current and future impacts of climate change, learning from good practices to promote transformative adaptation policies, plans and actions. The Paris Agreement calls for holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. This necessitates rapid, deep and sustained reductions in global greenhouse gas emissions, including from agrifood systems. Climate action in a coherent manner, as appropriate, in accordance with and dependent on national contexts and capacities through agrifood systems offers considerable potential to maximise co-benefits of adaptation and mitigation, while achieving other Sustainable Development Goals. FAO seeks to enhance its support to Members in their efforts with respect to climate change adaptation and mitigation, working towards climate-resilient and low-emission agrifood systems while striving to achieve the Sustainable Development Goals, in particular eradicating hunger and malnutrition. Climate action at global, regional, national and local levels across agrifood systems is fundamental to their transformation in a coherent manner according to, and dependent on, national contexts and capacities, including for the pursuit of other environmental, social and economic objectives.
