This document summarizes UNDP's efforts to support the integration of climate change adaptation into agriculture sector planning and budgeting in Vietnam. It outlines UNDP's role in making climate change knowledge usable for decision-makers by providing tailored tools and building local capacity. As examples, it describes mapping tools developed for Vietnam that incorporate climate vulnerability into existing planning processes, and how disaster risk reduction tools have been adapted to include climate change analysis. It also discusses the importance of public finance reviews for demonstrating climate-relevant expenditures and raising debates around funding. Key challenges discussed include balancing long-term climate projections with near-term risk management, tailoring tools to different scales, and building on existing government systems.
