Over the past three years, TMG Research, together with WWF Mesoamerica and ADIMI in Guatemala, and WOTR in India, have been exploring pathways to scale EbA at national and sub-national level. The goal was to develop new models of collaboration that prompt engagement across sectors and stakeholder groups. Through evidence-based advocacy and intense knowledge exchange about the value of EbA, a common vision for bringing EbA to scale has been created, uniting a range of different actors, including government, civil society, researchers, NGOs, and the private sector. These multi-stakeholder platforms led to the joint development of roadmaps, consisting of concrete action plans for scaling and mainstreaming EbA through various policies and programmes. Beyond joint design and planning, the roadmap process prompted voluntary commitments and spurred action. In Guatemala, for example, the process led to the integration of EbA into the Third National Communication to the UNFCCC, the revised NDC, as well into municipal development plans. In India, cross-sectoral collaboration for scaling EbA has been initiated, finding an anchor in the country’s popular watershed development programmes. This webinar will explore these roadmap development processes, outlining their specificities, success factors, and challenges. Representatives from civil society, government, the private sector, research, and the EbA donor and practitioner community, will discuss how such processes can be useful tools for creating enabling conditions to mainstream and upscale EbA. The webinar aims to inform discussions around this year’s summits, promoting EbA as an effective, scalable, and integrated adaptation solution with multiple benefits.
