Sustain COAST Deliverable 3.2: Cost structures for groundwater depletion and pollution preventing measures

This report summaries the main activities of the WP3 team on the project Sustain-COAST during the first half second year. Efforts were spent in making progress on the second task of WP3 (Task 3.2), which aimed to identify the cost structures for groundwater depletion and pollution preventing measures groundwater use for each case study of the four Sustain-COAST demonstration sites. The second task 3.2 aimed to analyze the cost structures for groundwater depletion and pollution preventing measures groundwater use in each case study. Variables under investigation including mitigation option should be considered in the analysis. The choice of the appropriate technique in each case study mainly depends on the issue site. This task considered at an early stage the potential common "Issue", which can be shared and agreed by all stakeholders in each case study. To this end, first, the mitigation options description, literature review and close interaction with the case studies partners were conducted. Second, the mapping of those options was performed as part of Task 3.2 for each case study. It is worth to be noted here, that the mapping exercise of the different mitigation options will be a dynamical process during and will be adjusted over the course of the project, where key stakeholders can be added at a different stage to enrich the multi-stakeholder partnership process. The provided information will give insights into assessing the sustainability of the current and future groundwater management strategies. This analysis will identify for each real site the areas of agricultural, domestic, and industrial water demand, the adequate mitigation option tackling the groundwater problems in the most vulnerable zones in terms of water resources availability, management and pollution risks
