Abstract	The aim of this work was to design and implement indicators for wetland monitoring, using Earth Observation (EO) techniques in the framework of the European Space Agency's GlobWetland project. Specific objectives included: (i) evaluation of monitoring requirements, (ii) design of a monitoring protocol and a geodatabase, and (iii) application and evaluation of the methodology in the study area (wetland of Axios-Loudias-Aliakmonas rivers delta), which was one of the prototype sites of the GlobWetland project. Analysis of data needs involved evaluation of the international, European, and national legislation that required monitoring and reporting. The resulting data requirements have been defined to describe the active pressures, their impact on the natural ecosystem and eventually the environmental state as a result of the pressures. To meet the requirements, existing datasets were evaluated for their usefulness, new satellite images were acquired, and historical archived images were obtained to use as the main source of data. Visual field observations were also conducted in time close to image acquisition. The monitoring protocol was designed, which contributed towards efficient monitoring of European Ramsar wetlands using a set of indicators. Also, a universal geodatabase was designed, which facilitated data storage, retrieval, analysis, and ensured standardized reporting. EO and GIS methods used during monitoring of the study area involved preprocessing of the satellite images, enhancement of information, information extraction, and derivation of indicators. Resulting thematic maps revealed and quantified the intensity of pressures in the vicinity of the protected wetland: intensive agriculture covered almost 50% of the study area, and several hundreds mussel farms were recorded. The state of the wetland was described with the seasonal change in the spatial extents of the water bodies (only 8%), and the spatial distribution of habitats (Annex I of Habitat Directive). Study of the changes that occurred during the last decade (1994-2004), revealed that irrigated agriculture did not increase significantly, but settlements and road network have expanded. The most notable change in the state of the wetland was a reduction in the delta extent, mainly due to detention of suspended material in diversion dams and decrease of water supply.
