The last IPCC (Intergovernmental Panel on Climate Change) report made public on February 19th, 2001 foresees an average increase in global temperatures ranging between 1.4°C and 5.8°C, as well as a rise in ocean levels from 9 to 88cm for the 21st Century. A system of mobile dikes known for their acronym, MOSE, was conceived in order to deal with a 60 cm increase in sea levels. The apparatus, which must function with timely precision in order to ward off the successive acqua alta, risks becoming a permanent featured, thus interrupting the tidewaters that regulate the natural hydraulic exchange from fresh to salt water, and in turn, the biological function and ecosystem of the wetlands. This unique ecosystem made of fresh and brackish water, is in the process of inexorably transforming itself into an arm of the sea in its central region, and into a swamp around its periphery. The elimination of a number of organic material has led to the eutrophication of the environment: only the Ulva rigida seaweed proliferates. Eutrophication is a biochemical transformation of bodies of water into which an excess amount of nutritional industrial waste is poured. As a result, the waterâs biological equilibrium is disturbed by a lack of dissolved oxygen. The Ulva rigida seaweed is the only species that has proliferated. The Ulva feed for the most part on phosphorus and nitrogen from the urban waste. For the last few years, biofuels have progressed forward, but their production alone, through oleaginous plants, cannot meet with our energy needs. In order to match the 49.35 million tons of petroleum consumed by Italian transportation, one would have to cultivate 118% of the total surface of the country with sunflowers! Studies conducted on micro-seaweeds have shed light on the basic concepts behind a prolific source of biofuel. Today various enterprises and research laboratories are pursuing this field, and looking for ways to optimize bio-production and extraction of the micro-algae using pumping techniques. Our project for the urban park of Sacca San Mattia consists of reinvesting the island in a Venitian, multi-functional approach to urban planning, in the context of an enlarged metropolitan, touristic center. The Drip Feed project on the Island of Sacca San Mattia puts into place an above ground Ulva rigida cultivation device that is in keeping with the Greenfuel system. A Saprophyte structure that ingests polluted waste from local industry, and conceptually redefines the lagoonâs future water level, without harming the natural state of the island. In a sense, this integration between production and consumption is carried out in the project Drip Feed: the planned construction of an industrial farm, where nothing can be removed, yet everything is for consumption on the site. This includes: biofuel for the lagoonâs transportation needs, seaweed to feed the tourists, oxygen for the water, and the CO2 emitted from the local industries, which is necessary for the farmâs operation. Our project fuses together every scale of society in a contemporary schizophrenia; the local scale - the activity of fishing; the regional scale - the merchant society and the port; the national scale â the industrial activity, and finally on the global scale - with tourism, a vessel for the cityâs lagoon-image, which is seeped in romantic literature, and still distributed by the majority of tour catalogues. Venice and its lagoon, a world of languid sentiments, of decadent love, the city of lovers, the place to take refuge far from the continental metropolises, while admiring the artistic beauty of this insular city. The Drip Feed project strengthens Venice, like Disneylandâs competitor, it modifies the environment and helps slow the physical destruction of the lagoon and the city. At the same time it is leads to the creation of urban environments that are adapted to catering to tourism. Drip Feed is a project for a high quality form of tourism that is more durable, sustainable, and which guaranties the continuation of productive activity, off-set from the central flux.
