The City of Venice Venice is one of the most famous cities in the world, strategically located in relation to both Italy and Europe. Venice is the capital of the Veneto Region , that is today one of the strongest economic regions in Europe. The City in figures: •Size: 457 km 2 •Population: 266,181 people •Population density per km 2 : 582.4 •Population in the centre and lagoon area: 38% •Population on the mainland: 62% HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Characteristics of the City/1 The Venetian territory can be divided into three main areas: •the Islands (old town) •the Lagoon •the mainland area - Mestre and Marghera (new town and industrialized area) The unique setting of the city of Venice contributes both to its appeal and to its vulnerability to flooding and environmental degradation HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003

Physical protection Crisis Factors to combat: Safeguarding activities: High water and sea storms: Dredging of lagoon channels Erosion of the coastline Restoration of minor islands Deterioration of jetties Re-opening of channels Urban fragility Algae harvesting Pollution and erosion : Removal of pollutant sediment Morphological deterioration Interventions for landfills Environmental deterioration Estuary phytopurification Oil-tanker traffic risks Distancing oil-tanker traffic HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Pollution in Venice Lagoon Manifestation : •Disappearance of animal and plant species •Weakening of the natural defences •Invasion of macroalgae Causes : •Porto Marghera industrial plant •Waste water discharge •Urban Lagoon Centres discharge •Pollution of sediment HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Pollution and Marghera industrial plant • The huge industrial zone at Porto Marghera on the mainland was built over a rich complex of salt marshes, filling in a vast area of the Lagoon. Its factories, in particular the petrochemical complex, have extensively polluted the soil and the Lagoon's waters. • Porto Marghera represents an old approach to development. Since the 1960s, when Italy's chemical industry met the first symptoms of an ongoing economic crisis, Porto Marghera has seen little investment or conversion. • Innovation & Conversion/ VEGA (Venice Science and Technological Gateway) is an initiative aimed at creating a strong link among intellectual, scientific and entrepreneurial resources, both local and international, as well as at implementing the sectors of search and that are concerned with new materials and information technology applications HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Pollution in Venice Lagoon < Standing time for pollutant substances. 53% of the pollution in the lagoon comes from agriculture and livestock and 47% comes from industrial, civil and urban sources. HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Pollution in Venice Lagoon Water transparency Marine eelgrass Disappearence of animal and plant species is an useful indicator. The decrease in eelgrass is particularly serious as it is important for the biodiversity of the Lagoon. Plant Species Bird Species HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Environmental quality The objective behind interventions for environmental quality aims at combating the factors contributing to the deterioration of the lagoon ecosystem, dividing them into: • erosive processes • different types of water and sediment pollution . In order to achieve this objective it is necessary to restore or defend typical morphological features within the lagoon and to reduce the pollutant substances . HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
Information Exchange There is need for: • Much better information within the international scientific community about management solutions to the environmental problems, including evaluation of those solutions already proposed (eg. the mobile barriers at the entrances to the lagoon) • A more coordination and cooperation among the decision takers, of the nature of the problem, the prognosis, the possible solutions and hierarchy of risk HyWaMIS – Hyderabad Water Management Information System Hyderabad, 23-24 September 2003
