Key messages • A holistic approach that recognises the need for climate finance, adaptation, loss and damage alongside climate mitigation is necessary to achieve sustainable food security under climate change. • The agricultural sector is one of those most vulnerable to climate change while also being a major driver of greenhouse gas emissions (GHG). Food security in a world of climate change necessitates developing resilience to the effects of climate change as a risk multiplier, and a reduction in agriculturally related GHG emissions. • Data-driven approaches, from precision agriculture and the use of artificial intelligence in agricultural production, to remote-sensing data to create integrated smart food and water management, can enhance the resilience of food systems under climate change. • Rapidly advancing biotechnological approaches provide a mechanism to introduce or identify traits that introduce resilience to both biotic and abiotic stresses on crops from climate change. This will be possible only through fair access to genetic resources, sharing of benefits, mobilisation of resources and capacity-building in low- and middle-income countries. • Food security is underpinned by access to fresh water, and climate change is increasing water scarcity in regions across the world. Developing smart water management practices that incorporate local, indigenous knowledge and are shaped to local conditions can help in addressing risks. • Agricultural extension services, citizen’s science, social innovations, awareness-raising and engagement with civil society institutions, women’s groups, NGOs, and policymakers and local communities can support addressing climate change impacts on food production. Gender imbalances, economic inequality, and inequitable food distribution all shape access and attitudes to food and nutrition and must be considered in policies to facilitate behaviour change towards greater food security. • International collaboration to improve global food security in a changing climate will need to minimise food loss and involve co-created, place-based initiatives that account for vulnerabilities and lack of access to nutritious food at sub-national and local scales, and which support investment in both new technological approaches and in-country capacity-building. • Integrating a focus on sustainable food systems into countries Nationally Determined Contributions (NDCs) as part of the Paris Agreement and in National Adaptation Plans can enable more joined-up actions to build resilience to climate change in food systems alongside reducing emissions from the sector. • Climate change impacts on food production present risks to agricultural trade, which can amplify food insecurity. Multilateral coordinated responses through international bodies like the World Trade Organization (WTO) can help facilitate global food security under climate change through use of the international standards and guidelines.
