The preservation of water resources in coastal areas in a key issues in a changing world. Coastal areas are among the most densely populated regions of the world, and this poses several threat to their natural balance. Among the key issues, particularly in areas of arid and semi-arid climate, is the over-exploitation of freshwater resources. The intensive use of water resources may lead to water scarcity, which is detrimental to the economic development and may compromise human health of the less favoured societal sectors. Over-exploitation of water resources may cause severe pressures on aquifers and surface waters, producing adverse effects on water quantity and quality (excess nutrient, pollution, lower biodiversity) among which is a change in the balance at the freshwater-seawater interface with dramatic saltwater intrusion and loss of aquifer resources. It is apparent how a proper management of this issues requires a more refined understanding of the dynamics of such systems.
The round table aims at bridging the gap between technological and scientific development on one side and the needs for practical management of coastal aquifer systems on the other side. In particular, the last few decades have seen major advancements in the characterization of the subsurface system and its interactions the land and marine surface. While these techniques are state-of-the-art at a scientific level, their understating and use by practitioners and decision makers is still in its infancy.
The four invited speakers cover a wide range of expertise, ranging from ground based characterisation methods such as Electrical and Electro-Magnetic techniques, to proximal and remote sensing and from climatic and land use impact assessment to a wide view of policy making and impacts to the marine system. The round table will be composed of four short talks with the aim of eliciting also the audience discussion.
