Expert Support Groups
Supporting the co-operation and uptake of Nature-Based Solution across Europe
The GreenEsteem Expert Support Groups (ESGs) are national advisory bodies established in Austria, Bulgaria, and Poland to support the co-creation, validation, and valorisation of knowledge on Nature-Based Solutions (NBS). Bringing together independent experts from academia, public authorities, the private sector, and civil society, the ESGs provide strategic guidance and stakeholder perspectives that help ensure the project's activities and results are relevant, evidence-based, and responsive to national needs.
Working closely with the GreenEsteem consortium throughout the project, the ESGs contribute expertise, share emerging policy and practice insights, and support the development of impactful and locally relevant solutions for knowledge valorisation and Nature-Based Solutions.
