To respond urgently in times of crises we need to be ready. Researchers need the know-how and tools to develop rapid evidence synthesis at short notice, and coordinated networks need to be able to translate, communicate, and share evidence at a moment’s notice so that policymakers can use that evidence. The Juno Evidence Alliance will be a cutting-edge global platform that empowers evidence-based policy in agriculture, food systems, and climate adaptation. By utilising artificial intelligence and proven research methodologies, the aim is to streamline the synthesis of diverse data sources, providing timely, relevant, and high-quality conclusions for governments, funders, and policymakers. With Juno, decision-makers can accelerate progress, reduce costs, coordinate messages, and shape a sustainable and resilient future for the benefit of all.
