Agenda 21 recommends adopting planning and management systems that facilitate the integration of environmental components such as air, water, land and other natural resources, using landscape ecological planning (LANDEP) or other approaches that focus on, for example, an ecosystem or a watershed.
In 1992, seven Thai cities joined together in a project to develop and apply environmental planning guidelines for community priority-setting on environmental issues. Stakeholder groups were established with municipal support to engage residents and key sectors in the process. Specific projects are being funded to address the identified priorities. Chaing Mai municipality has developed its own Local Agenda 21 within this process.
