2. SUMMARY
This work described a methodology to design ecological networks for
a territorial scale, as an instrument for territorial and urban planning. Under the sustainability
paradigm, it represented a means to mitigate the phenomenon of habitat fragmentation.
Therefore, the methodology was applied to the triangle of the municipalities of Agudos –
Bauru – Piratininga, in San Paolo State, Brazil, in order to support the ongoing work for the
Participatory Plan for the municipality of Agudos. The area characterization was carried out
highlighting the real capabilities of the territory in terms of suitability for the implantation of
green corridors for ecological networks. Suitability analysis is determined by a multicriteria
evaluation with weighted linear combination method (WLC). A set of environmental and
physical information about the study area was derived from pedology investigations developed
during the land use capability stage. This information were reconsidered and completed to take
into account the biodiversity conservation issue and the green system preservation issue, and
later evaluated by the WLC method. Over the suitability map, the best paths for the ecological
network were identified through a least cost method in order to interconnect the nodal point of
the network, that means, ecological valuable patches with core area and fluvial strips near
Batalha River, the most important river in the region. The assessment of the ecological
network proposals is based on the landscape ecological principals, by comparing the actual
landscape and the modified landscapes. Thus, the outcomes are expressed in terms of
