Different marine and coastal activities have diverse economic, environmental, and socio-cultural objectives, which can lead to conflict when these multidimensional activities coincide spatially or temporally. This is sometimes driven by a lack of understanding or other users’ needs and consequentially adequate planning and the utilization of acommonlanguage is essential. By using a transparent approach based on multi-criteria analysis, we characterize and establish priorities for future development/conservation for all users in the coastal area using six representative European Case Studies with different levels of complexity. Results varied according to location, but significantly it was found that stakeholders tended to favour ecological and social over economic objectives. This paper outlines the methodology employed, the results derived, and the potential for this approach to reduce conflict in coastal and marine waters. Keywords: case studies, coexist, conflict (reduction), European Coastal Zone, marine spatial planning, multi-criteria analysis, stakeholders.

Indicator-based approaches are often used to monitor land degradation and desertification from the global to the very local scale. However, there is still little agreement on which indicators may best reflect both status and trends of these phenomena. In this study, various processes of land degradation and desertification have been analyzed in 17 study sites around the world using a wide set of biophysical and socioeconomic indicators. The database described earlier in this issue by Kosmas and others (Environ Manage, 2013) for defining desertification risk was further analyzed to define the most important indicators related to the following degradation processes: water erosion in various land uses, tillage erosion, soil salinization, water stress, forest fires, and overgrazing. A correlation analysis was applied to the selected indicators in order to identify the most important variables contributing to each land degradation process. The analysis indicates that the most important indicators are: (i) rain seasonality affecting water erosion, water stress, and forest fires, (ii) slope gradient affecting water erosion, tillage erosion and water stress, and (iii) water scarcity soil salinization, water stress, and forest fires. Implementation of existing regulations or policies concerned with resources development and environmental sustainability was identified as the most important indicator of land protection.

Marine spatial management is challenged by complex situations in European countries where multiple stakeholder interests and many management options have to be balanced. EU policy initiatives such as the proposed Marine Spatial Planning Directive, are in different ways targeting area allocation in European waters. In this circumstance, EU marine management needs assessments based on a satisfactory evaluation framework design that can ensure a transparent treatment of different types of information including interests, values, and facts. The main goal of this article is to introduce an evaluation framework applicable to marine management in European countries. This socalled CoExist framework maps out different types of relevant knowledge to assess future possibilities for use or no-use of marine areas and links this with appropriate management measures. The CoExist framework is based on the principles of ensuring transparent treatment of different types of information as well as appropriate stakeholder representation which can ensure legitimacy. Empirical findings in six European case studies have been obtained while conducting the CoExist framework. Applying the basic principles of the CoExist framework when planning future management directions of the coexistence of multiple activities in the long-run will expectedly affect the ecological and social-cultural goals by counterbalancing the economic ones.

Lipids can be anaerobically digested to methane, but methanogens are often considered to be highly sensitive to the long-chain fatty acids (LCFA) deriving from lipids hydrolysis. In this study, the effect of unsaturated (oleate [C18:1]) and saturated (stearate [C18:0] and palmitate [C16:0]) LCFA toward methanogenic archaea was studied in batch enrichments and in pure cultures. Overall, oleate had a more stringent effect on methanogens than saturated LCFA, and the degree of tolerance to LCFA was different among distinct species of methanogens. Methanobacterium formicicum was able to grow in both oleate- and palmitate-degrading enrichments (OM and PM cultures, respectively), whereas Methanospirillum hungatei only survived in a PM culture. The two acetoclastic methanogens tested, Methanosarcina mazei and Methanosaeta concilii, could be detected in both enrichment cultures, with better survival in PM cultures than in OM cultures. Viability tests using live/dead staining further confirmed that exponential growth-phase cultures of M. hungatei are more sensitive to oleate than are M. formicicum cultures; exposure to 0.5 mM oleate damaged 99% ± 1% of the cell membranes of M. hungatei and 53% ± 10% of the cell membranes of M. formicicum. In terms of methanogenic activity, M. hungatei was inhibited for 50% by 0.3, 0.4, and 1 mM oleate, stearate, and palmitate, respectively. M. formicicum was more resilient, since 1 mM oleate and >4 mM stearate or palmitate was needed to cause 50% inhibition on methanogenic activity

Ireland : Coexist project - Interaction in coastal waters - ISBN 9780992660208 - 76 p.
This guidance document provides a comprehensive assessment of the conflicts and synergies between fisheries, aquaculture and other activities in the coastal zone in six COEXIST case study areas. It forms deliverable D5.2 of the COEXIST project and synthesises deliverable D5.1, which provides a more detailed description of the methods used and results. This document also accounts for the views and expectations of stakeholders that were raised at the COEXIST stakeholder workshop held in Bergen, Norway, parallel to the ICES (International Council for the Exploration of the Sea) Annual Science Conference 2012. Over 30 stakeholders representing a variety of sectors, including aquaculture, fisheries, coastal zone management, tourism and energy, as well as 20 members from the COEXIST project and ICES representatives, attended this event. The stakeholders and COEXIST members were from Denmark, Finland, France, Germany, Ireland, Italy, Norway, Portugal, Spain, the Netherlands and the United Kingdom. The workshop aims were firstly to communicate the COEXIST project results and progress to stakeholders and the second major aim was to receive stakeholder feedback on the development of best practice guidance for spatial planning to integrate fisheries, aquaculture and further demands in the coastal zone.
