**GRIDA3** (Shared Resources Manager  for Environmental Data Analysis and Applications) is an interdisciplinary project funded by the Italian Research Ministry (Prog. n. 1433/2006 [[http://www.miur.it|MIUR]] FAR D.Lvo 297/99). Designed to provide a //holistic// description of //environmental problems// and practical answers to questions of central importance, the project will result in an advanced //problem-solving// tool for the integration, through a computing portal, of human know-how, simulation software, instrumentation and resources for data communication, storage, visualization, and computation. The project will supply a //Grid// infrastructure for collaborative work, built for the sharing of data and applications located at multiple sites across federated domains, public and private. 

{{ Immagine-038.jpg}} The extent and the complexity of environmental problems and their consequences on the ecosystem, human health and economic development make an integrated, cross-disciplinary approach necessary to increase the technical knowledge and public awareness, to support the management of natural resources and to develop a systematic change in land uses. To cite some of the environmental challenges addressed by the project, consider the constant increase of contaminated sites, the non-rational use of natural resources, and the hydro-geological risk related to meteorological extreme events and climate variability.
To tackle these complex problems in environmental science and engineering the Grid approach is emerging worldwide as a formidable tool allowing to provision a computational task with administratively-distant resources. Thus, Grid computing reflects a //[[conceptual framework]]// rather than a physical resource.

The project started in July 1st, 2006 and will last 3 years. The [[http://www.sardegnaricerche.it/index.php?xsl=370&s=38389&v=2&c=3134&archivio=&vd=2&fa=1&c1=|kick-off]] meeting of the project took place on November 28, 2006, at [[http://www.sardegnaricerche.it/|Polaris]], the Scientific and Technological Park of Sardinia based in Pula (Cagliari, Italy). The event was the opportunity to illustrate the [[Aim of this research|base elements]] for the project, roles and other project planning activities. The gathering included, in addition to the members of the project team, researchers and potential clients, all with a position of responsibility in the construction of the environmental policy in Sardinia. 

Within this philosophy of //sharing// and //collaboration//, a prototype of integrated decision support system, //[[http://datacrossing.crs4.it|Datacrossing]]//, has been recently implemented at CRS4. The system is a suite of partly in-house developed modules composed of GIS technologies, mesh generators, hydrological and pre/post processing codes within a data-Grid environment to predict the impact of point/non-point source pollution and quantify the uncertainty due to the model application. The Grid infrastructure has been designed using //[[https://www.irods.org/index.php/IRODS:Data_Grids,_Digital_Libraries,_Persistent_Archives,_and_Real-time_Data_Systems|iRODS]]// technologies in order to access data and resources across a distributed computing environment.
