The ESPON InTerAlp project is part of a larger effort to improve the understanding and support territorial governance and spatial development across the Alpine region. The Alpine region is home to several major European cities (among others: Munich, Milan, and Vienna) and is traversed by key transport corridors that connect Northern Europe with the Mediterranean. It is also a region of significant environmental importance, as it provides vital ecosystem services, such as water supply and biodiversity conservation, to the rest of Europe.

The ESPON InTerAlp project provides a systematic exploration of the specific spatial dynamics, challenges and opportunities associated with Alpine interface territories. The analysis addresses a number of key questions, including the definition and delineation of Alpine interface territories, the identification of common challenges and opportunities, and the review of governance frameworks and instruments for Alpine spatial planning and development.

The InTerAlp project zooms into a number of relevant case studies to examine specific interface regions in more detail. These cases serve to provide an in-depth exploration of different regional settings. The selection of case study regions covers a wide range of geographical locations and territorial characteristics. In general, interface territories are spread all across the Alps – some are more urbanised, others are predominately rural. There are interface territories with cross-border characteristics, and some are directly linked to national capitals.

Alpine interface territories link mountainous and inner-Alpine areas with pre-Alpine lowlands and, thus, are a very specific territorial type: Highly dynamic flows and interdependencies as well as controversial stakeholder interests meet in a rather limited spatial framework. Organising sustainable spatial development in this geographical context is a challenge. These challenges extend beyond administrative boundaries and require pan-Alpine strategies and cross-border spatial planning and development instruments.

The case studies of the project TERRA-RES (Territorial Exaptive Resilience along EU Eastern Borders) were purposively selected to represent a diverse range of border regions in the EU's eastern borderlands, each facing unique challenges and opportunities in the context of geopolitical changes, environmental crises, and social and economic disruptions. The selection criteria included:

This study provides a comprehensive analysis of territorial exaptive resilience along the EU's eastern borders, examining how regions mobilise and repurpose existing assets and capabilities in response to external challenges or shocks. Through rigorous quantitative analysis and detailed case studies, the research advances our understanding of regional adaptation and transformation in peripheral areas, contributing to both theoretical discourse and policy development.
