This paper provides a baseline geographic characterization of the mangrove ecosystem of the Bragantinian coastal region in the Stare of Pará, northern Brazil, which is the research area of the joint Brazilian-German Mangrove Dynamics and Management (MADAM) project. The paper looks at the natural environmental conditions, the status of the coastal resources, the socio-economic situation of the rural population and the sustainability of existing human activities based on stock-raking between the years 1997 and 2000. Human use of this mangrove ecosystem is characterized by about 15 products, which have either subsistence value or generate monetary income for the local rural population. The importance of these functions for the rural household increases with the distance from the urban center. In the primary production sector, agriculture and artisanal fisheries are the main sources of income in the wider Bragantinian region. Both industries are characterized by many small operators. The industrial sector is very underrepresented throughout the region. In the service sector, especially coastal tourism is gaining increasing importance. It was found that the ecology of the ecosystem of Caeté River estuary as a whole can still be considered as rather undisturbed by human activities, but there is evidence of considerable and increasing remote and local interference by humans. This includes increased sedimentation by land clearance in the catchment area of the estuary, intensification of fisheries due to population growth and lack of alternative livelihoods, changes in the hydrological regime of the mangrove ecosystem by improvements to the network of roads, and development of tourism along the beaches. Presently the control of the allocation of resources within this region rests predominantly in the hands of local individuals. An overall plan for a sustainable management of the coastal zone is still lacking.
