This international network brings together 621 exceptional sites in 117 countries, combining conservation of biodiversity with cultural, economic and social development.

The Dordogne basin covers 24,000 square kilometres, eleven départements and five regions. It was the eleventh natural reserve recognized in France, and is also the largest. The founding principle of the Dordogne Basin World Biosphere Reserve is that the preservation of its river heritage, the resources and the benefits it provides, are the conditions for the future development of this territory and the well-being of its inhabitants.

The objective is for this international recognition to stimulate the imagination and consideration of the environment in the projects of management and planning. It also contributes to the international engagement of the Dordogne.

From the volcanoes of Auvergne to the Gironde estuary, the landscapes of the Dordogne basin are as diverse and remarkable as the nature environment is generous. The Dordogne river and its tributaries mark their imprint the territory and its cultures. Many activities benefit from this heritage, and thanks to everyone's efforts, this magnificent area has managed to preserve a subtle balance between economic development and the preservation of its ecosystems.

These are the characteristics that influenced UNESCO's decision.
