The Albufera of Valencia is a highly eutrophied coastal lagoon. Its ecological importance is recognised internationally. The complexity of the system functioning, as well as its location in a highly populated environment (marshland surrounded by rice crops), makes difficult the recovery of the system, in spite of the works carried out by the different organisms. The Department of Environment is developing an integral study to determine which are the necessary performances in order to make possible the sustainable development of the area as well as the conservation of the ecosystem. This and other studies aim to determine the current state of the problem and the necessary main works to solve it. With the current information, and keeping in mind the result of the last evaluation, it is necessary to contribute a bigger volume of water of good quality to the lagoon. This water will maintain the general quality of the lagoon and also, the arrival of the polluting substances will be eliminated.
