Introduction: Since 1992, the project for the Rehabilitation of the Ciénaga Grande de Santa Marta (PROCIÉNAGA) has been trying to define and carry out a management plan to improve the damaged environmental and socio-economic conditions of the region. For this purpose the Colombian Environmental Ministry, the BID/IDB, the Regional Autonomous Corporation of the Magdalena (CORPAMAG), the Institute of Oceanographic and Coastal Investigations (INVEMAR), the Regional Planning Council of the Atlantic Coast, and the German Society for Technical Cooperation, GTZ, among others, are joining their forces.
