Abstract

The strategic environmental assessment of territorial and urban planning to adopt in 2004 will be facing a
number of challenges, such as that of ecological connectivity, this principally in those areas undergoing an
intense fragmentation process. The paper offers a new parametric methodology that has been formalised by
a use of mathematical language supported by a topological analysis, and brought forward by using GIS.
This method permits the elaboration of a diagnosis of the connectivity within terrestrial landscape ecosystems
on the basis of both ecological functional areas, and a computational cost-distance model which includes
the barrier effect. We defined two new compound indices: one for ecological connectivity and another for the
barrier effect. The application of this methodology to the Barcelona Metropolitan Area has allowed not only
a cost-effective assessment of the current situation, but a set of quantitative assessments and maps of the
impacting on the landscape and ecological connectivity of different land use or infrastructure planning
scenarios.
