L’informe “Solucions basades en la Natura (SbN) a la comarca del Maresme” recull les accions implementades per integrar la natura en la gestió del territori. S’han desenvolupat mesures com la restauració d’ecosistemes, la creació d’espais verds i la millora de la gestió de l’aigua per reduir els efectes del canvi climàtic i augmentar la resiliència del medi ambient. Aquestes accions tenen com a objectiu combatre problemes com l’erosió del sòl, les inundacions i la pèrdua de biodiversitat, contribuint així a un desenvolupament més sostenible i a la millora de la qualitat de vida a la comarca.

Aquest projecte ha estat finançat pel Consell Comarcal del Maresme i s’ha desenvolupat per l’Institut d’Ecologia Aquàtica (UdG) en col·laboració amb Engloba Consulting. L’objectiu ha estat promoure les SbN com una eina efectiva per afrontar els desafiaments ambientals del Maresme. S’ha volgut exposar com aquestes solucions poden mitigar els efectes del canvi climàtic, reduir riscos naturals i afavorir un territori més resilient. A més a més, s’ha buscat impulsar la col·laboració entre administracions, entitats i ciutadania per avançar cap a un model de desenvolupament més sostenible i equilibrat amb l’entorn.

Tackling climate change and biodiversity loss are two of the great global challenges of the 21st century. The nature-based solutions (NbS) approach creates an opportunity to meet efforts on the two agendas while producing other co-benefits beyond climate resilience and biodiversity conservation. This opportunity becomes even more relevant in areas with both high climate vulnerability and special interest for conservation. Coastal wetlands in the Mediterranean basin are under severe threat from urban sprawl, mass tourism and climate change. Coastal lagoons, dune systems and halophilic ecosystems are considered as priority habitats of community interest for conservation by the European Habitats Directive. In the Catalan coast, these ecosystems are fragmented and isolated, and ecological protection and restoration efforts are essential. In this context, the present work analyzes the case of de-urbanization and ecological restoration of La Pletera salt marsh by the Life Pletera project (2014–2018), interpreting it within an NbS approach and assessing its effectiveness as a strategy for climate adaptation and biodiversity conservation. The analysis brings insights for the effectiveness assessment of the project during the first years after implementation, gathers elements on the factors and constraints that made its implementation possible and reflects on future challenges so that its effectiveness is lasting in the medium and long term.

An urban development project was started in the La Pletera salt marshes in the 1980s but was halted and abandoned because of the economic crisis of the 1990s. Between 2014 and 2018, a Life Nature project (the Life Pletera project) was carried out for the definitive ecological restoration of the salt marsh. As part of this restoration project, the man-made structures, the breakwater, the promenade, the access streets and all the filling material where the houses were to be built were removed. This article offers 1) a brief description of the historical process that took what was supposed to be a set of tourist homes to what it is now a functional, protected salt marsh included in the Montgrí, les Illes Medes i el Baix Ter Natural Park, 2) a description of the restoration process that was carried out and the ecological criteria that were used for the restoration, 3) some initial data about the response of the ecosystem during the first years immediately after the restoration, and 4) some data on visitors’ perception of the conversion of this natural system.
