First launched in 2008, the Adventure Tourism Development Index (ATDI) is a global ranking to assess the competitiveness and potential of adventure tourism in more than 190 countries. The index was developed in partnership by the Adventure Travel Trade Association (ATTA) and George Washington University International Institute of Tourism Studies (GW IITS).
Christina Beckmann, head of Tomorrow’s Air, initiated the ATDI based on experiences and observations she had with her consulting teams on adventure tourism development projects in Latin America, Asia and Europe.
