An ecomuseum is a museum focused on the identity of a place, largely based on local participation and aiming to enhance the welfare and development of local communities. Ecomuseums originated in France, the concept being developed by Georges Henri Rivière and Hugues de Varine, who coined the term ‘ecomusée’ in 1971. The term "éco" is a shortened form for "écologie", but it refers especially to a new idea of holistic interpretation of cultural heritage, in opposition to the focus on specific items and objects, performed by traditional museums.
There are presently about 300 operating ecomuseums in the world; about 200 are in Europe, mainly in France, Italy, Spain, and Poland.
Introduced by the French museologist Hugues de Varine in 1971, the word ecomuseum has often been misused and the definition of an ecomuseum is still a controversial matter for contemporary museology. Many museologists sought to define the distinctive features of ecomuseums, listing their characteristics.
Following a complexity approach, in recent definitions, ecomuseums are more properly defined by what they do rather than by what they are.
The ecomuseum phenomenon has grown dramatically over the years, with no one ecomuseum model but rather an entire philosophy that has been adapted and molded for use in a variety of situations. As many more ecomuseums are established across the world the idea has been growing and the changes in the approach towards the philosophy are reflected in the reactions of the communities involved. In recent time particular significance is the rise in ecomuseology in India, China, Taiwan, Japan, Thailand, Vietnam and Cambodia, with significant increase in Italy, Poland, the Czech Republic and Turkey.
Ecomuseums are an important medium through which a community can take control of its heritage and enable new approaches to make meaning out of conserving its local distinctiveness.
An Ecomuseum is a dynamic way in which communities preserve, interpret, and manage their heritage for a sustainable development. An Ecomuseum is based on a community agreement.
