It is necessary to appreciate that tourist destination areas evolve and change over time, both responding to, and being altered by, changes in tourism. They are not static environments, and need responsible and pro-active planning and management. Reliance upon local initiatives, uncoordinated planning, and self-regulation in a situation of ill-defined responsibility, will not result in a secure long-term future for either the tourist industry or the environment of the destination area. Coordination of policies, pro-active planning, acceptance of limitations on growth, education of all parties involved, and commitment to a long-term viewpoint, are prerequisites to the successful linking of tourism and sustainable development.
