Although having some limitations in indication of sustainable use of coastal ecosystem due to the lack of data at different time points, the maps of sustainable use of coastal ecosystems in case studies are exercises showing the qualitative approach to assessment of sustainable use of natural resources. Using indicators of ecosystem sustainability for assessment and mapping coastal resources use is a simple method but requires datum sequences at different time points. Making maps of sustainable use of coastal ecosystems also provide the change in area of each level (very sustainable, sustainable, unsustainable and very unsustainable) of the use of coastal ecosystems. I. INTRODUCTION II. METHODOLOGY Within the frame work of the project Mapping sustainable use of natural ‘Solutions for Environmental Contrasts in resources in coastal area of case studies is Coastal Areas’ – SECOA project, maps of based on DPSIR (Driving forces, Pressure, sustainable resources use in SECOA case State, Impact and Response) frame work studies of partner countries as Belgium, analysis or more quantitatively the India, Israel, Italy, Portugal, Sweden, the sustainability indicators and index. UK and Vietnam have been made to The sustainable use of coastal interpret and provide more information on ecosystems in case studies was assessed at assessment of natural resources use. To do 4 levels: assessment of the sustainable use of natural - Very sustainable resources then produce the maps, three - Sustainable approaches were taken into account, - Unsustainable including DPSIR framework analysis, - Very unsustainable sustainable use indicators and sustainability index with increasingly quantitative Base maps and their scales are selected assessment. However, the later approaches by SECOA partners. The map scales are require more systematic data that are not selected mainly dependent on the always collected and become one of the geographical scope of selected case studies critical limitations of these methods. and the available data, indicators and Coastal ecosystems or their components in indices. Geographic information system the case studies were selected and assessed (GIS) technology is employed for mapping. based on the main criteria and indices. There are two exceptional cases of the partners of the UK and Sweden in mapping of sustainable use of coastal natural 239 resources. The UK partner developed two 1. Belgian case studies kinds of indicators, including indicators of SECOA Belgian case studies include the sustainability and relative indicators of ones of Brugge and Oostende. Because sustainability to indicate the areas under these two case studies are close to each higher or lower pressure levels without other and in the same coastal system, the actually quantifying them and use these coastal ecosystems in the two case studies indicators to produce maps. Swedish were assessed and mapped together. partners have taken into account the 2050 Outputs of the analysis and calculation of scenarios of human activity and climate sustainability indicators from the set of change to map the land use change in sustainability of the coastal ecosystem SECOA Swedish case studies. The (Table 1) allow mapping the sustainable use mapping and analysis of Swedish case of the coastal ecosystem in case studies. studies has gone through four steps: 1) Maps of sustainable use of coastal Combination of selected layers indicating ecosystems in Belgian case studies were status, values and threats/pressures (maps made for non-built area (including of status 2010, maps of pressures 2050) agriculture, natural and semi natural using GIS; 2) Assessment of the degree of habitats, and open spaces) in the period of pressure based on qualitative and seven years from 2001 to 2007, showing an quantitative information about specific unstable trend in area of sustainable use. areas; 3) Combination with earlier and The total of non-built area in the case proposed responses, measure areas of studies was decreased over years.
