Champagne-Ardenne (in French pronounced as /ʃɑ̃paɲaʁdɛn/) is a former administrative region of France, located in the northeast of the country, bordering Belgium. Mostly corresponding to the historic province of Champagne, the region is known for its sparkling white wine of the same name.
The administrative region was formed in 1956, consisting of the four departments Aube, Ardennes, Haute-Marne, and Marne. On 1 January 2016, it merged with the neighboring regions of Alsace and Lorraine to form the new region Grand Est, thereby ceasing to exist as an independent entity.[2]
Its rivers, most of which flow west, include the Seine, the Marne, and the Aisne. The Meuse flows north.
The rail network includes the Paris–Strasbourg line, which follows the Marne Valley and serves Épernay, Châlons-en-Champagne, and Vitry-le-François. The LGV Est TGV line also connecting Paris and Strasbourg opened in 2007 and serves Reims with a train station in the commune of Bezannes.
The region's canals include the Canal latéral à la Marne and Marne-Rhine Canal, the latter connecting to the Marne at Vitry-le-François. These are petit gabarit canals.
The Vatry International Airport, primarily dedicated to air freight, has a runway 3650m (11,980feet) long. The airport is in a sparsely populated area just 150km (90miles) from Paris.
The population of Champagne-Ardenne has been in steady decrease since 1982 due to a rural exodus. With 1.3 million people and a density of 52/km2, it is one of France's least populated regions. After a brief period of stabilization in the 1990s, the region's population is now among the fastest "dying" in Europe, with several municipalities losing people at a faster rate than a lot of Eastern European areas, especially in the Haute-Marne department. The region is among the oldest in France, has a weak fertility rate, and its immigrant population, while growing, is still minimal compared to the national average.
