The Consortium for the Sustainable Development of the Andean Ecoregion (CONDESAN) was established in February 1993 after a series of consultations among different regional stakeholders working on sustainable development. Inspired by Agenda 21, which emerged from the Rio 1992 Earth Summit, and influenced by the ecoregional approach, CONDESAN was created as a platform to promote research for development throughout the Andean region. The Consortium is now celebrating its 20th anniversary.
