Abstract
The development of GIS based methodologies supports a program for
monitoring the territorial dynamics that are occurring in the Estorãos rural
watershed (NW Portugal). GIS integrates spatial databases from different
research and development projects, with the purpose of understanding: (i) the
relationships between land use processes and changes, and environmental
management policies; (ii) the extent of environmental impacts due to forest fire
as well as extending and intensifying agriculture; and (iii) the influences of
natural conditions and human activities on water quality and ecosystem
sustainability. The diversity of natural conditions and population dynamics, the
(de)forestation, the expansion, density and typology of road networks, the
processes of urbanization in the flood plain, and the rising turistic search from
external actors, fundament the importance of a GIS based watershed monitoring
program. These conditions and processes increase watershed management
complexity, namely at a protected wetland in the bottom valley (regional
protected landscape, site PTCON00020 of Natura Network 2000, and
international RAMSAR site 1613) related to the structure of the landscape, and
the quantity and quality of the water resources and the associated biodiversity.
The challenges of sustainable land use and the growing quantity and quality of
the available spatial databases, allow greater modelling capacity and data
accessibility, facilitating public participation, and also aiding and better guiding
political and technical actions.
Keywords: spatial decision support system, watershed, geographic information
systems, landscape planning and management.
