Expected Outcomes

Projects funded under this call are expected to contribute to the following outcomes in the Danube-Black Sea region:

1. Stronger community leadership and capacity for long-term water protection. Danube-Black Sea region’s communities gain the skills, confidence and resources to lead restoration and pollution-reduction efforts in their rivers, lakes, seas and coastal areas. Local communities build lasting capacity to manage and protect their water environments well beyond the project period.

2. Proven innovative solutions delivering measurable environmental and societal improvements in Danube-Black Sea region. Projects test and demonstrate practical, community-led solutions (integrating technological, nature-based, social, cultural, regulatory, financial or governance innovations) that provide verifiable evidence of effectiveness, usability, environmental and societal impact under real conditions in the Danube-Black Sea region.

3. Enhanced multi-stakeholder collaboration and knowledge exchange. Projects bring together diverse actors (communities, local authorities, researchers, SMEs, civil society organisations, underrepresented stakeholders, etc.) to cooperate, build a shared understanding of sustainable water management practices, and foster collective capacity to address complex water challenges. Projects effectively integrate Social Sciences and Humanities (SSH) expertise and social innovation to match innovative solutions with real community needs, ensuring sustainable engagement, behaviour change and long-term impact on community practices and values.

4.   Increased readiness for regional deployment and transferability of solutions. Projects generate practical results, methods, and tools that can be replicated or adapted in other communities across the Danube-Black Sea basin, with community-led monitoring and local data supporting evidence-based decision-making. Projects develop deployment plans that outline clear pathways, technical requirements, institutional arrangements, funding attraction and timelines for replication and upscaling beyond the project period and geographical scope.

5.   Strengthened verifiable contribution to the Mission Ocean and Waters’ objectives and targets. Projects deliver quantifiable progress towards one or more objectives and targets of the Mission Ocean and Waters, contributing with examples, stories, data, methodologies and lessons that strengthen the Mission-wide monitoring framework and inspire further community-driven action across Europe.
