This Study looks at how tourism has been taken into account in local Agendas 21, as drawn up and implemented by local authorities. As local authorities face the impacts of tourism development, the Agenda 21 planning framework is useful to define strategic goals for all stakeholders, and to effectively use tourism to achieve a community's main goals. A coherent collection of case studies of the implementation of Local Agenda 21 structures and processes in many destinations, it highlights lessons learned, and compares various situations ranging from developing to established municipalities and regions, in continental and island settings.
