OPERAs project


A descriptive video of the OPERAs project, a European ecosystems recovering project, and its sub-project called Hybrid Dunes, carried out by S·G·M and the Metropolitan Area of Barcelona, with the aim of recovering and maintaining the coastal dunes ecosystem of the metropolitan beaches.

Ecosystem services at the Collserola Park surroundings


First, an algorithm that explains where people is:


The algorithm’s regression line shows its accuracy, with a 0,96 variation index:

So, with this algorithm we are able to deduce the number of people living in a specific area, only by the analysis of this area’s urban tipology. For example:

Those are the people susceptible of using more frequently the areas of the Park near to those specific urban areas.

To evaluate the spatial distribution of the people along the Collserola Park, an analysis of the effort  for those people to go from an origin to any part of the Park is carried out.

The resulting image shows that for the same effort, from 2 different origins, different distribution areas appear:

In another way, the frequentation at the sides of the Park can be associated also to the impact of unleashed dogs and stray cat colonies on badger and genet populations.

At Turó de Montcada an example can be seen:

The orange area represents the farthest area from the unleashed dogs presence. Those “free” dog areas match the badger and genet potential distribution areas.

The same happens when we look at the areas away from the presence of stray cats:

Suspiciously, again it is matching with the badger and genet potential distribution areas.

What if we look at the city by means of structure, functionality and change?
