Deltas are widely identified as vulnerable hotspots at the interface of the continental land mass and the world’s coastal boundaries. With respect to increasing risks related to global change, the concept of ecosystem services has a capacity to contribute to safety of both, social and natural systems and vulnerability reduction. Here we study the role of the pool of ecosystem services in terms of flood mitigation and vulnerability reduction model, in a deltaic margins of the European coast (the complex land-sea system of the Waddenzee, comprising the Netherland inner coast and the islands, North Sea) then applicable to a wide variety of deltaic regions in developing areas. Extensive tidal mud flats, saltmarshes, dune ridges and sandy spits between the mainland and the chain of islands, support valuable sediment and primary production regulation along the seaside of these ecosystems. The system includes an incentive ecosystem structure (dune system) whereby economic agents would choose development activities that reduce vulnerability (flooding protection and erosion prevention) as well as satisfy production objectives (recreation and tourism).

Vulnerability values extracted using remote sensing processors represent an innovative development of systems and methodologies. Using remote sensing observations, we investigate the distribution of spatial vegetation and substrate patterns controlled by changes in environmental variables acting on deltas, and we speculate the conditions under which the Real Elementary area can be defined.
