This paper describes a participatory watershed management project which uses
GIS-based mapping as a basis for dialog and collaboration between local
communities and partner institutions in Mae Chaem watershed, northern Thailand.
Through the participatory mapping process, local communities were able to
document local patterns of resource utilization and changes over time. This
allowed outsiders to better understand the context of land use and more clearly
see the potential of the area. Output maps from projects such as this are
important information resources for communities, local watershed management
networks, local governance, and other institutions. Such maps can also provide a
basis for dialog in efforts to solve problems and conflicts regarding natural
resources management at different scales.
