From Cross-Border Cooperation to Cross-Bordering: Implications for Regional Governance and Sustainable Development at the Franco-Italian Alpine Border

When Boundaries Become Resources: The Global Development Significance of Cross-Border Regions

In an era where globalisation and regionalisation proceed in parallel, boundaries are no longer simple dividing lines. For many cross-border regions, borders are both administrative obstacles and arenas for institutional experimentation. The EU actively promotes cross-border cooperation through policy instruments such as Interreg, turning border areas into laboratories for testing new governance models. This dynamic is particularly striking in the Alpine region—which combines the fragility of high-mountain ecosystems with the frequency of transnational mobility, and faces multiple pressures from climate change, demographic shifts, and the energy transition.

A recent study published in *Sustainability*, focusing on the French-Italian Alpine border, analyses in depth how cross-border cooperation gives rise to a new process of regional integration—"transfrontierisation." The study, by scholars Emma Brunet and Federica Corrado from the Polytechnic University of Turin, centres on the "urban-mountain system" formed by Savoy, Aosta Valley, and the Turin metropolitan area, using the A-MONT project (2021-2027) under the Interreg ALCOTRA programme as its empirical entry point.

From Project Cooperation to Institutional Evolution: The Core Logic of Transfrontierisation

Traditional research tends to view cross-border cooperation as temporary project-based collaboration, focusing on concrete outcomes and obstacles. However, this study reveals a deeper dynamic: cross-border cooperation is reshaping sub-national networks, stabilising governance practices, and cultivating shared territorial perceptions. The researchers call this "transfrontierisation"—a gradual process through which cross-border cooperation transcends isolated projects, progressively structuring regional governance without, however, replacing existing institutional frameworks.

This perspective carries important implications for global development research. In many border regions, especially in developing countries, cross-border cooperation often faces challenges such as institutional asymmetry, weak administrative capacity, and short-term project cycles. The Alpine case shows that, although these obstacles are widespread, repeated interaction can still accumulate into informal networks and shared diagnostic mechanisms, thereby laying the groundwork for long-term governance. This provides sociological support for international cooperation arrangements that seek to promote regional integration through cross-border projects.

The Alpine Laboratory: Functional Interdependence and Ecological Fragility

The Alpine border is a unique research sample. It contains both international metropolises (Turin) and sparsely populated mountain areas; both highly developed transport corridors and ecologically sensitive high-altitude zones. The study points out that these regions face common challenges in mobility, ecological transition, demographic change, risk management, and multi-actor governance. The misalignment between functional interdependence and administrative boundaries makes cooperation necessary, yet also full of tension.Particularly noteworthy is the environmental dimension. The continuity of mountain ecosystems does not recognize administrative boundaries: climate adaptation requires cross-watershed coordination, disaster risk requires transnational early warning, and biodiversity conservation requires joint action. Therefore, cross-border cooperation is not only a tool for economic integration, but also a vehicle for ecological governance. Under the ESG framework, this corresponds to the intersection of environment (E) and society (S)—the resilience and equitable development of cross-border communities are highly dependent on governance capacity that transcends borders.

Empirical Findings: Core-Periphery Patterns and Governance Asymmetry

The study adopts a mixed-methodology approach, combining quantitative analysis of the two ALCOTRA project phases 2014-2020 and 2021-2027, qualitative interviews with local and supra-local actors, and a critical review of recent Integrated Territorial Plans (PITER). The results reveal several key patterns:

First, significant core-periphery differences in participation. Not all border actors participate in projects with equal intensity. Metropolitan core areas often possess stronger institutional capacity and resources, while peripheral mountain areas more often serve as "project objects" rather than "project subjects." This inequality in participation may exacerbate existing regional disparities, reminding policymakers of the need for more targeted capacity-building interventions.

Second, persistent administrative capacity gaps. Cross-border cooperation demands highly complex project management skills, including multilingual communication, cross-border legal coordination, financial compliance, and more. The research shows that gaps in these capacities among administrative actors at different levels persist over time, leading to uneven quality of cooperation. This is particularly important for developing countries: capacity building should be viewed as an integral component of cross-border cooperation, rather than a peripheral adjunct.

Third, informal networks compensate for institutional fragmentation. Formal institutions struggle to cover all cross-border interaction scenarios, so informal connections become a lubricant. Interpersonal trust and working rapport built up through long-term cooperation effectively mitigate coordination costs arising from overlapping or absent jurisdictions. But this also means that if personnel rotate or the political environment changes, fragile social capital may be lost—a point often overlooked in sustainability assessments.

Fourth, the emergence of shared territorial diagnoses. Despite persistent institutional differences, cross-border actors gradually develop mutual recognition of common problems and priorities. This "diagnostic consensus" is a prerequisite for deeper integration and also lays the cognitive foundation for future joint responses to transnational challenges such as climate crises and public health events.

Implications for Global Sustainable Development Governance

Although the Franco-Italian Alpine case is a high-income European region, its experience has generally transferable value. From the perspective of global development research, at least the following implications can be drawn:

1. Cross-border governance is a prerequisite for climate resilienceClimate disasters do not respect national borders. Glacier retreat, flood risks, and biodiversity loss in the Alpine region require cross-border responses. If border actors cannot form institutionalized coordination mechanisms, any unilateral policy will be inefficient. Many mountain regions in the Global South (such as the Himalayas and the Andes) face similar cross-border ecological problems but lack the institutional support of something like Interreg. International climate finance and development cooperation should provide more support for the establishment of cross-border governance frameworks.

2. Center-Periphery Inequality as an Endogenous Challenge for Cross-Border Cooperation

If cross-border cooperation fails to proactively address asymmetries in participation capacity, it may reproduce or deepen existing development gaps. ESG investment and the Sustainable Development Goals (SDGs) emphasize "leaving no one behind." In border regions, this means designing "periphery-friendly" cooperation mechanisms, such as providing technical assistance to small-scale actors, simplifying project application procedures, or setting minimum participation quotas.

3. Informal Networks Need Formalized Safeguards

Research shows that informal networks are crucial in cross-border governance. However, over-reliance on interpersonal trust is fragile. Policymakers should consider how to transform informal networks into more resilient institutional forms—for example, establishing permanent cross-border working committees, setting up joint secretariats, or using digital platforms to accumulate cooperative memory. This is similar to the concept of "institutional resilience" in development finance: making cooperation not merely based on personal relationships but embedded in organizational structures.

4. Cross-Border Cooperation as an Investment in Long-Term Governance Capacity

The benefits of cross-border cooperation are often difficult to quantify in the short term. But as this study shows, sustained interaction gradually improves information asymmetry, builds mutual trust, and forms shared governance practices. Therefore, when international development agencies evaluate cross-border projects, they should not only focus on direct outputs (such as bridges built or meetings held), but also pay attention to the accumulation of "institutional capital"—namely, actor networks, knowledge-sharing mechanisms, and collective action capacity. This long-term perspective is precisely the core of the "governance" (G) dimension in ESG.

Conclusion: Cross-Bordering as a New Dimension of Regional Sustainability

The study of the Franco-Italian Alpine border tells us that cross-border cooperation is not just a policy tool, but a profound process of regionalization. In this process, borders transform from obstacles into resources, from dividing lines into connecting belts. The concept of cross-bordering helps us move beyond "project checklist" style evaluations and instead focus on how cooperation reshapes networks, practices, and identities.

For global development research, this case reminds us that sustainable cross-border governance requires three capabilities simultaneously—institutional design capacity (creating rules), relationship maintenance capacity (cultivating trust), and diagnostic coordination capacity (sharing knowledge). All three are indispensable. When the world faces overlapping climate, health, and economic crises, regions that can achieve effective cross-border coordination will possess greater adaptability and competitiveness.Cross-border cooperation is no longer just a peripheral issue in regional governance, but a frontier for global sustainable development. From the Alps to the Hindu Kush, from the Rhine to the Mekong, similar logic is playing out at different scales. Understanding "cross-borderization" means understanding the micro-foundation of future global governance.
