This report summarizes progress in implementing activities under the Nairobi work programme on impacts, vulnerability and adaptation to climate change (NWP) between April 2025 and March 2026. It highlights how the NWP continues to function as the UNFCCC knowledge-to-action hub for adaptation and resilience through the co-creation, curation and delivery, with the engagement of diverse knowledge holders, of timely, understandable and actionable knowledge and know-how tailored to the evolving needs of Parties, especially developing country Parties. It describes outcomes and impacts of key areas of work under the NWP, including generating practical insights and exploring pathways that can inform efforts to enhance access to and mobilization of finance for adaptation, implementing the Lima Adaptation Knowledge Initiative with a focus on the Amazon subregion and strengthening the engagement of universities through the UN Climate Change Universities Partnership Programme. In addition, it documents lessons learned and strategic opportunities for supporting countries and communities under the NWP through delivering knowledge and know-how. Building on lessons learned, work under the NWP will continue to involve strengthening the delivery of practical knowledge, enhancing engagement with diverse knowledge holders, and supporting the co-creation, curation and delivery of timely, understandable and actionable knowledge and know-how for scaling up adaptation action and strengthening resilience to climate change impacts across systems and communities, including in the context of formulating and implementing national adaptation plans. The indicative NWP workplan for 2026–2027, contained in the annex, reflects these priorities with the aim of ensuring that the NWP remains responsive to the evolving needs of Parties.
