The project’s technical and scientific work was organised into four complementary work packages that jointly developed and tested frameworks, empirical evidence, and methods to assess how spatial planning can enable transformative biodiversity outcomes.
WP1 analysed SP&MIs through a systematic assessment of 58 best-practice cases using multi-criteria coding and lexical analysis, producing a taxonomy of biodiversity-oriented planning practices. A functional catalogue of SP&MIs was developed and assessed against key biological principles—habitat area, quality, and connectivity—and against implementation barriers using a capacity-gap framework tested in planning contexts. WP1 showed that SP&MIs often secure space for nature, while transformative effects depend on policy mixes, monitoring requirements, and supportive governance arrangements.
WP2 strengthened Environmental Assessment instruments (EIA and SEA) by developing a benchmark for biodiversity integration and applying it to the comparative analysis of around 200 EIA and SEA reports across four European countries. Systems-thinking methods, including causal loop diagrams, were introduced to map links between activities, impacts, ecological processes, and mitigation measures. Additional analyses addressed mitigation hierarchies, tiering, and cumulative impacts, advancing EA from reactive mitigation toward more strategic biodiversity planning.
WP3 examined E&FIs relevant to spatial planning by analysing the EU Renewed Sustainable Finance Strategy and assessing design and implementation gaps in biodiversity-related E&FIs. The Ecosystem Services Opportunities framework was adapted to spatial planning, linking biodiversity objectives, planning stages, and instrument selection. WP3 demonstrated that E&FIs support biodiversity transformation only when well designed, monitored, and integrated into planning processes.
WP4 integrated and tested findings through the Arenas for Transformation, analysing how SP&MIs, EAIs, and E&FIs interact in real planning contexts. By refining theories of change and synthesising cross-WP evidence, WP4 demonstrated that transformative biodiversity outcomes arise from coherent combinations of instruments aligned with planning cycles and institutional contexts.
