Abstract

The Lagoon of Marano and Grado has been experiencing some remarkable environmental impacts, which have affected the high-value natural ecosystem and consequently influenced relevant socio-economic aspects. One of the main problems relates to the diffuse contamination of soil and groundwater in the mainland, as well as sediments in rivers and in the lagoon itself. The need to ensure safe navigation conditions in the lagoon and in the Corno River serving Porto Nogaro harbour is another critical emergency. Other environmental issues of concern are: loss of morphological diversity, watershed basins’ pollution loads and protection of lagoon habitats. Due to the emergency situation, a Special Commissioner has been appointed by the national government to proceed with the resolution of the most critical problems. A specific “Operational Plan of interventions” was therefore elaborated in 2009. Approaching problems and solutions in an integrated way, the Plan represents one of the tools for the sustainable development of the lagoon. It strongly supports the adoption of adaptive management, foreseeing the periodical updating and improvement of objectives, strategies and interventions. The Plan also identifies the need for coordination among institutions and involvement of stakeholders as key elements for the implementation of adaptive management.
