[CROSSGOV] - Governance mechanisms for cross-border functional areas

Integration in cross-border regions can be understood through two main dimensions. The first relates to interactions across the border, shaped by the intensity of cross-border flows and the barriers that may affect them. The second concerns the degree of spatial convergence between the territories, reflected in similarities or differences in their economic, social, and territorial characteristics. These integration processes do not unfold in the same way everywhere. They vary depending on the specific characteristics of the territories involved, highlighting the need to better understand how different types of cross-border regions operate in practice.

Across Europe, cross-border integration has been supported by a variety of tools. These include economic instruments such as the single market and Interreg programmes, institutional frameworks like European Groupings of Territorial Cooperation (EGTCs) and Eurodistricts, and functional approaches that aim to address sector-specific obstacles—particularly in the efficient provision of cross-border public services. Over time, considerable progress has been made, especially in amending mechanisms to resolve legal and administrative barriers, where the recently adopted BRIDGEforEU agreement stands as a good result of these efforts.

Despite these advances, important research gaps remain. Border regions face a wide range of challenges that go beyond legal and administrative barriers. These include economic, political, cultural, cognitive, and interpersonal factors that can influence cooperation. In addition, administrative systems and governance practices differ significantly across EU Member States. This diversity highlights the limitations of “one-size-fits-all” solutions and underlines the need for approaches that are better adapted to specific territorial contexts.

Cross-border functional areas (CBFAs) offer a promising way to further reduce obstacles and facilitate the movement of people, goods, and knowledge across borders. While several cooperation models have already identified and mapped different types of CBFAs, much less is provided at the pan-European level. In this context, the CROSSGOV project delivers a first comprehensive understanding of CBFAs across the ESPON space, covering their multifaceted nature.

Cross-Border Functional Areas delineation | While the project is not singular within this endeavor (where recent examples can be highlighted – such as the Revision of the Schengen Borders Code, or the piloting of the EUROSTAT Working Group work on cross-border cities and FUAs), CROSSGOV's core innovations lies in its standardized, pan-European delineation of 85 CBFAs at the municipal (LAU) level, addressing longstanding data scarcity in border regions. CROSSGOV methodology focuses on five weighted indicators within 25km border corridors (covering land borders and short-sea ferry links under five hours): population density, minimal cross-border car travel times, Twitter-derived mobility catchments, Facebook social connectivity and harmonized natural hazard risks assements. Functionality values are calculated per municipality, with high-intensity "cores" (strict CBFAs) buffered by catchments and merged to resolve overlaps via iterative GIS processing. This yields intensity zones (high, low) applicable across urban hubs (e.g., Basel Eurodistrict), rural peripheries (e.g., Spanish-Portuguese border), and topographically challenging areas (e.g., Mont-Blanc).

Cross-border governance compendium | The project delivers a first compendium of multi-level governance structures, by analysing 199 cross-border cooperation initiatives across ESPON space. These initiatives are classified according to several criteria, including the type of cooperation structure and participating entities (such as Euroregions, EGTCs, and working communities), the number of countries involved, and their thematic focus. The analysis highlights the wide diversity of governance arrangements: ranging from informal cooperation networks to more formalised structures based on legally binding agreements. It also examines how well these governance structures correspond to the realities of cross-border functional areas (CBFAs). The compendium identifies a number of strengths, such as the presence of multi-level mandates that bring together actors from different levels of government. At the same time, it points to several challenges, including mismatches between governance boundaries and functional cross-border dynamics, as well as vulnerabilities during crises, as illustrated by the border closures experienced during the COVID-19 pandemic.

Comprehensive overview of the cross-border regions | Complementarily, the project provides in-depth thematic analyses at the pan-European level. These cover all relevant dimensions for the cross-border integration, such as accessibility and mobility, environment and climate risks, economy, social connections and governance and cooperation. Delivered as interactive mapping, these present a structured analytical process, combining territorial evidence with assessments of development potentials and opportunities.

Additional outputs include 10 case studies, covering a broad range of territorial settings: involving monocentric (Trinational Eu-redistrict Basel), polycentric (Greater Region), as well as two-centred (Helsinki-Tallinn region, Fehmarnbelt region) examples. Furthermore, the analysis also deals with linked settlement groups such as twin cities (Komárno-Komárom and Gmünd-České Velenice), settlement axes (Newry-Dundalk region), and neighbouring settlements forming a cross-border urban fabric (Eurocity EUROBEC). These were developed in close collaboration with stakeholders, practitioners, and policymakers. The aim was to gain a deeper understanding of the main development patterns and dynamics – existing and future, challenges, solutions, and governance structures shaping cross-border cooperation and their functional areas.

Policy questions 

The project aims to support EU, national, regional policies in answering the following key policy questions:

How to define cross-border functional areas across Europe? How to calibrate the analytical definitions with the actual realities of functional cross-border areas where people live and work in?
How to enlarge the indicator-based knowledge on border-regional functioning in a difficult data environment?
What are the main patterns and dynamics as well as challenges and solutions within border regions and their cross border functional areas?
Which governance structures are in place in cross-border regions? How to ensure vertical and horizontal policy coherence to capitalise on the potentials in cross-border functional areas?

The project encompasses the entire ESPON programme area.
