The Blue Banana: Europe’s hidden economic engine stretching from Liverpool to Milan
In short: Spanning from North West England to Northern Italy, the Blue Banana is a massive, discontinuous corridor of urbanization. Home to roughly 100 million people, this industrial powerhouse has shaped European development since the post-war era, though its exact borders and economic influence remain subjects of intense academic debate.
The concept of the Blue Banana, or the European Megalopolis, was introduced in 1989 by French geographer Roger Brunet. Originally termed the European Backbone, it described a corridor of industry and services connecting Liverpool to Milan. The name itself emerged from a collaboration between Jacques Chérèque and an artist illustrating an article by Josette Alia; the blue color likely referenced the European Community flag or the blue-collar workers who powered the region's industrial rise.
Brunet’s original model was exclusionary, notably omitting Paris due to his belief that French economic centralism had severed the nation's connection to this broader European development. However, later interpretations have been more inclusive. A 1991 European Commission study challenged the concept, suggesting it was more a product of regional competition than an empirical reality, and proposed a curved path extending to Barcelona. Despite these critiques, the region remains the continent's primary concentration of industry, capital, and population.
Today, the corridor is evolving. While historically considered the economic core, recent research by Capoani et al. in 2024 highlights the challenges faced by its peripheral edges, such as the United Kingdom following Brexit and Northern Italy. As urbanization continues, the region is not merely shifting but expanding into a star-shaped network. With 72% of the global population projected to live in cities by 2050, the Blue Banana continues to serve as a critical, if fluid, focal point for European economic policy and urban planning.
