“…A Europe-wide top-down overview was compiled for all countries in the EU-27 (Renetzeder et al, 2008) and for 4 sensitive region types (i) postindustrial regions, (ii) mountains, (iii) coasts and (iv) islands, applying the following 10step protocol: (1) geographical identification of Europe's potentially sensitive post-industrial zones, mountains, coasts and islands at the NUTS levels 2 and 3, (2) the literature review to identify sustainability issues and data sources, (3) assessment of the necessity of collecting complementary data, (4) data collection on key issues in sensitive areas, based on the sustainability impact issues identified by the European Impact Assessment Guidelines, (5) consultation with relevant stakeholders with regard to their view on sustainability issues in sensitive regions throughout Europe, which is particularly relevant for sensitive region types that are underrepresented at the NUTS levels 2 and 3 (e.g., islands), (6) simple web-based questionnaire to collect qualitative and (semi)quantitative data on key sustainability issues, (7) statistical analysis and clustering of sensitive regions based on available indicators to identify classes of post-industrial zones, mountains, coasts and islands with similar environmental, social and economic characteristics, (8) generation and interpretation of maps with key issues of sensitive regions; here the most sensitive regions were delineated, (9) drafting of sub-survey reports, and compilation into a final report, and (10) integrated and comparative analysis of key sustainability issues across sensitive-area types and against a 'regular' standard, e.g., European average (Dilly et al, 2008). The bottom-up intra-regional resolution level procedure was essentially done with the same protocol.…”
