Mesorégion

Mesorégion is a term used in regional planning and geography to denote an intermediate-sized territorial unit, typically smaller than a macro-region and larger than a micro-region. It serves as a functional area that possesses a degree of economic, social, and environmental coherence, often centered around a metropolitan area or a significant urban hub. The concept aims to capture a scale of organization that is relevant for policy implementation, infrastructure development, and strategic planning, bridging the gap between national or supra-regional strategies and local administrative boundaries.

The definition and application of mesorégions can vary across different countries and academic disciplines. In some contexts, they may be defined by statistical criteria, such as population size, economic activity, or commuting patterns. In others, they are established through administrative or political designation, reflecting historical development or specific policy objectives. The core idea is to identify an area with shared characteristics and interdependencies that warrant a coordinated approach to development and governance.

Mesorégions are often considered crucial for understanding spatial dynamics and for designing effective territorial policies. They can facilitate the integration of different sectors, such as transport, housing, and environmental management, within a coherent geographical framework. By focusing on these intermediate-scale regions, policymakers can better address issues of regional disparities, promote balanced development, and enhance the competitiveness of their territories. The concept emphasizes the interconnectedness of urban and rural areas within a defined spatial unit.
