Abstract:
The availability of robust and reliable spatial information on ecosystem condition is of increasing importance in informing conservation policy. Recent policy requirements have sparked a renewed interest in conceptual questions related to ecosystem condition and practical aspects like indicator selection, resulting in the emergence of conceptual frameworks, such as the System of Environmental-Economic Accounting - Ecosystem Accounting (SEEA-EA) and its Ecosystem Condition Typology (ECT). However, while such frameworks are essential to ensure that condition assessments are comprehensive and comparable, large-scale practical implementation often poses challenges that need to be tackled within stringent time and cost frames.We present methods and experiences of the national-level mapping and assessment of ecosystem condition in Hungary. The assessments covered the whole country, including all major ecosystem types present. The methodology constitutes four approaches of quantifying and mapping condition, based on different interpretations of naturalness and hemeroby, complemented by two more using properties that 'overarch' ecosystem types, such as soil and landscape attributes. In order to highlight their strengths and drawbacks, as well as to help reconcile aspects of conceptual relevance with practical limitations, we retrospectively evaluated the six mapping approaches (and the resulting indicators) against the indicator selection criteria suggested in the SEEA-EA. The results show that the various approaches have different strengths and weaknesses and, thus, their joint application has a higher potential to address the specific challenges related to large-scale ecosystem condition mapping.

Abstract:
Ecosystems provide multiple services that are necessary to maintain human life. Agroecosystems are very productive suppliers of biomass-related provisioning ecosystem services, e.g. food, fibre, and energy. At the same time, they are highly dependent on good ecosystem condition and regulating ecosystem services such as soil fertility, water supply or soil erosion regulation. Assessments of this interplay of ecosystem condition and services are needed to understand the relationships in highly managed systems. Therefore, the aim of this study is twofold: First, to test the concept and indicators proposed by the European Union Working Group on Mapping and Assessment of Ecosystems and their Services (MAES) for assessing agroecosystem condition at a regional level. Second, to identify the relationships between ecosystem condition and the delivery of ecosystem services. For this purpose, we applied an operational framework for integrated mapping and assessment of ecosystems and their services. We used the proposed indicators to assess the condition of agroecosystems in Northern Germany and regulating ecosystem service control of erosion rates. We used existing data from official databases to calculate the different indicators and created maps of environmental pressures, ecosystem condition and ecosystem service indicators for the Federal State of Lower Saxony. Furthermore, we identified areas within the state where pressures are high, conditions are unfavourable, and more sustainable management practices are needed. Despite the limitations of the indicators and data availability, our results show positive, negative, and no significant correlations between the different pressures and condition indicators, and the control of erosion rates. The idea behind the MAES framework is to indicate the general condition of an ecosystem. However, we observed that not all proposed indicators can explain to what extent ecosystems can provide specific ecosystem services. Further research on other ecosystem services provided by agroecosystems would help to identify synergies and trade-offs. Moreover, the definition of a reference condition, although complicated for anthropogenically highly modified agroecosystems, would provide a benchmark to compare information on the condition of the ecosystems, leading to better land use policy and management decisions.

Abstract:
Urban ecosystems are the areas where built infrastructure covers a large proportion of the land surface but the main source of ecosystem services provision is the green infrastructure. This provision is very much dependent on the particular combination of green spaces such as parks or vegetation belts and paved areas such as buildings and streets. The spatial arrangement of these elements is an important parameter which could be used for the assessment of the ecosystem condition in the urban areas. An integrated index of spatial structure is proposed which incorporates built types and land cover from the Local Climate Zones (LCZ) concept with urban ecosystems' classes developed on the basis of MAES typology. An algorithm has been developed for index generation using an urban ecosystems' database and remote sensing data. The index is used to define vegetation cover in urban ecosystems and assess their condition as a part of the assessment framework. It is also applied in the assessment of several ecosystem services through quantification of ecosystem services' indicators or as an indicator in a complex assessment. The results show that, although most urban ecosystems in Bulgaria are assessed as moderate and good condition, very few of them have very good condition and about 3.5% have very bad condition. The highest scores are defined for urban green areas while the lowest are for transport networks. The use of an integrated index in urban ecosystem services' assessment is represented by examples for global and local climate regulation. The results are used to develop maps of ecosystem services supply capacity for selected cities. The overall analysis indicates that the urban ecosystems in Bulgaria have a moderate to good capacity for local climate regulation and moderate to low capacity for global climate regulation. The integrated index of spatial structure provides an appropriate basis for characterisation and assessment of the urban ecosystems condition and ecosystem services following the requirements of the EU Biodiversity Strategy and the MAES process. The proposed approach enables the internal heterogeneity of the urban ecosystems at national level to be defined, this being one of the main challenges in studying urban ecological systems.

Abstract:
Forests set natural conditions and embody a repository of biological diversity that represents a myriad of ecosystem services for human well-being. The spatial patterns and the forest ecosystems' dynamics over time make the forests of particular environmental significance for the provision of ecosystem services. The terrestrial biodiversity and the sustainable management strategies' demand for mapping and assessment of the dynamics for the condition of forest ecosystems by drawing attention to the soil properties. In order to take on that task, the data series obtained by the <i>International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests</i> (ICP Forests) for the period 1986–2016 were found as appropriate quantitative indicators that convey information about the ecosystem's capacity to provide certain regulating ecosystem services. The ICP Forests Level I sites, located in the Central Balkan region, provide consistent information, which is collected on a regular basis about observed forest stands. The primary focus of the present research is to conduct a biophysical assessment of the forest ecosystems and to define their overall condition regarding two time series – the periods 1992/1993 and 2015. This study attempts to introduce an innovative approach and aims at linking the existing ICP Forests network dataset with the ecosystem services concept and the identified spatial units from the CORINE Land Cover (CLC) polygons for the territory of Central Balkan National Park. On this basis and through the implementation of GIS techniques, the dynamics of soil properties in selected forest ecosystems was analysed with regard to their capacity to supply relevant ecosystems services, which were assessed and mapped. The biophysical data provides robust information on the ecosystem services and the results show the variations in the capacity of different forest sub-types to provide ecosystem services within a well-defined land cover unit. Additionally, the research work intended to review the generated outcomes with reference to the DPSIR (driver-pressure-state-impact-response) method by giving feedback on the changes in the terrestrial ecosystems in the last 25 years. Further application of the mapping approach in assisting the communication in the decision- making process is also discussed.

Abstract:
The assessment and mapping of ecosystems and their services is considered an important action that effectively contributes to proper understanding of how ecosystems support human well-being, and furthermore &ndash; to promote the sustainable use of natural resources. The diversity of cultural landscapes, especially in mountain areas, is a significant prerequisite for a variety of cultural ecosystem services that are valuable for the society. This evaluation is the basis for environmental management practices and policymaking. The study presents an approach for assessment and mapping of cultural ecosystem service (CES) &ldquo;Cultural heritage&rdquo; that is recognised as important and is provided by mountain protected areas (PAs) in &ldquo;Pirin&rdquo; National Park. The data from the Management Plan of &ldquo;Pirin&rdquo; NP were used for characterization and biophysical assessment of the condition of forest ecosystems and their potential to provide CESs. The analysis of the results revealed that the conservation regime allowed the territories to preserve a high degree of naturalness and a very good ecological condition as 94.80% of forest ecosystems are assessed with score 4 &ndash;&ldquo;good&rdquo; condition and 0.44% are with &ldquo;very good&rdquo; condition &ndash; score 5. The majority of forest ecosystems with &ldquo;very good&rdquo; ecological condition are Pinus peuce forests, located mainly on the territory of the reserves &ldquo;Bayuvi Dupki- Dzhindzhiritsa&rdquo; and &ldquo;Yulen&rdquo;, proving the importance of the protective regime of the territories. Forest ecosystems with average and high capacity to provide ES &quot;Cultural heritage&quot; prevailed, which is consistent with well-preserved and unique nature, the diversity of landscapes, and species richness. Considerable areas were assessed with score 5 &ndash; very high capacity, mostly on the territory of the reserves &ldquo;Bayuvi Dupki- Dzhindzhiritsa&rdquo; and &ldquo;Yulen&rdquo;, and at the foothill of the huts.

Abstract:
Habitat maintenance as an ecosystem service (ES) is essential for the protection of natural capital, however, it is among the most challenging services for definition and evaluation. The present study is focused on assessing and mapping habitat maintenance ecosystem service in Rila and Pirin Mountains in Bulgaria for strategic planning purposes by better understanding the link between the potential of providing this ecosystem service and biodiversity in five protected areas (PAs). An integrated approach for the assessment of the condition of ecosystems in PAs and their potential to provide ecosystem services was applied and further developed in the present study. The results showed that the conservation regime allowed the territories to preserve a high degree of naturalness in a very good ecological condition – 96477 ha (73%) of the total case-study area, and 33078 ha (77%) of the target PAs, respectively. The potential of ecosystems to provide habitat maintenance ES is high to very high for 84% of the total studied area (81258.9 ha) and for 96.4% (31906 ha) of the area of the target PAs. A current assessment and mapping show the role of protected areas as spatial natural capital assets that purposefully and actively support their prioritized habitat maintenance functions as spatial guarantors for the sustenance of rich packages of material, regulating, and cultural functions in significant geographic areas. The results demonstrate the importance of protected site management in mountain areas in ensuring sustainable cooperation and consumption of ecosystem services in peripheral mountain communities of the European Union highly dependent on available natural capital.

Mapping and Assessment of Ecosystems and their Services (MAES) are central to the EU Biodiversity Strategy to 2020. Action 5 of the Strategy’s second target asks all EU member states to map and assess the state of ecosystems and their services in their national territories. Such comprehensive mapping and assessment builds on several individual tasks and their systematic integration. Therefore, an integrated and operational framework is needed, supporting and coordinating these activities. The presented framework builds on existing work done by the European Commission’s MAES Working Group and provides a clear nine-step approach including the identification of relevant questions or themes to be addressed, identification and mapping of ecosystem types, ecosystem condition and ecosystem services, their integration and dissemination of results. This framework can be used to set-up related research and development initiatives and to guide involved scientists, decision-makers and practitioners through the different steps and related tasks of the process.

Abstract:
Mountain ecosystems play an essential role in sustainable mountain development, providing benefits and values to humanity not only for the rich biodiversity they contain, but also because of their important role in climate regulation, water cycle, provisioning of recreation, tourism, cultural or spiritual values. The high biodiversity of the mountain areas allow the provision of a wide range of ecosystem services. However, different impacts to the environment threaten the delivery of these services and, consequently, the quality of life of people, both living in the mountains and outside the mountains. Recognizing, demonstrating and capturing the value of ecosystem services can play an important role in setting policy directions for ecosystem management and conservation and, thus, in increasing the provision of ecosystem services and their contributions to human well-being. Quantifying and mapping of these benefits can also help managers and decision makers to realize the importance of these sites for conservation and to allow the proper understandings of the impacts of mountain forest ecosystems on territorial development and welfare of local populations.The paper aims to outline the relevance and applicability of the ecosystem services approach for the assessment of the condition of mountain ecosystems and the services, they provide, for better understanding by the scientific community and to support decision makers in sustainable management of mountain regions.

Abstract:
Information on changes in the area of different ecosystems is needed in order to establish an accounting system for ecosystem conditions and services. Currently, there are no comprehensive field mappings for the German federal states that obey a uniform mapping system. To create a nationwide "ecosystem accounting", it is necessary to develop a uniform system of ecosystem classifications that can consistently deal with diverse nationwide data sources on the extent and condition of ecosystems, some of which use their own forms of classification. Against this background, we present a concrete proposal on how to combine and blend GIS land-use and ecosystem data that is compatible with EU-wide approaches with other regularly collected data sources, for example, from sample-based surveys, so as to generate a complete, updatable picture of the state of Germany's ecosystems. The area shares of ecosystem types (ETs) can be shown in maps. Allocation tables with different classes or levels (layers) enable an ecosystem extent accounting, which are used to help draw up balances (area balance, status balance, service balance) and can be further detailed, depending on the task at hand. First results and trends of areal changes of main and sub-ecosystem types in Germany, based on the proposed classification system, are presented and discussed. However, the brevity of the considered timeframe (the three periods 2012-2015-2018) does not yet allow us to pinpoint trends or migratory movements, as these may be masked by methodological changes in the classification of land use and land cover. Nonetheless, the presented system for accounting changes in ecosystem areas should be continued and developed in the future in order to create a useful tool for biodiversity monitoring in Germany.

Abstract:
Coastal areas have various potential resources, both physically, socio-economically and biologically. This situation places enormous physical and social pressure on coastal areas, increasing their vulnerability to various hazards such as storms, flood waves and tsunamis, sea level rise and land subsidence. The coastal area of ​​Semarang City is facing this threat. In a literature review conducted by researchers, apart from the imminent danger, there is also the potential for mangrove ecosystem resources around the Opak River estuary which can be used as a natural embankment to reduce the impact of coastal disasters. The aim of this research is; (1) mapping of existing mangrove ecosystems and their management; and (2) updating the Action Plan for Mangrove Ecosystem Management and updating community and local community perceptions of mangrove ecosystem services as a way to reduce the risk of coastal disasters. Obtain research materials using FGD techniques, in-depth interviews and secondary data documentation; Processing, analysis and presentation of data using qualitative research methods. Participatory mapping of the current condition of the mangrove ecosystem will be carried out to determine the level of public knowledge about the opportunities and problems of the mangrove ecosystem. The results of the participatory mapping are also used as material in focus group discussions that establish a therapeutic action plan with different options such as: B. Restoring damaged mangrove vegetation, developing ecosystem land, empowering communities to manage ecosystems, and using ecosystems as a means of transportation for ecotourism. and representative tourism. The process of developing and implementing an action plan for ecosystem management is a participatory management model which can then be developed with several other elements in research on coastal natural resource management as a means of disaster risk reduction.&#x0D; &#x0D; &#x0D;

Abstract:
Ecosystem accounting is a tool to integrate nature into decision-making in a more structured way. Applying the use of nationally available datasets at catchment scale and following the System of Environmental Economic Accounting-Ecosystem Accounting (SEEA-EA) framework, we present results from a catchment case study in Ireland, highlighting findings specifically in relation to the development of ecosystem extent and condition accounts. In the absence of a national ecosystem map, CORINE landcover mapping formed the basic data for extent and type of ecosystems, distinguishing woodlands and forest, peatland and heathland, grasslands and cropland and urban areas, with limited coverage of linear freshwater rivers, hedgerows and coastal ecosystems. Additional remote sensing data provided higher resolution at catchment scale, while limited site-level survey data were available. Condition data gathered for reporting under the EU Water Framework Directive were available at sub-basin level for surface waterbodies. Data were available at national level for habitats reported for the EU under the Habitats Directive (59 habitats reported), covering ~ 25% of the study area. Data for ecosystem types outside of these reporting frameworks were in the form of ancillary data only, providing information on pressures, threats and intensity of use. Our findings in Ireland reflect work across the European region, highlighting the role of data gathering and stakeholder engagement. We outline some of the data gaps to provide information for future research and alignment of data for the purpose of NCA, both at catchment and national scale.

Abstract:
Anthropogenic and natural disturbances can cause degradation of ecosystems, reducing their capacity to sustain biodiversity and provide ecosystem services. Understanding the extent of ecosystem degradation is critical for estimating risks to ecosystems, yet there are few existing methods to map degradation at the ecosystem scale and none using freely available satellite data for mangrove ecosystems. In this study, we developed a quantitative classification model of mangrove ecosystem degradation using freely available earth observation data. Crucially, a conceptual model of mangrove ecosystem degradation was established to identify suitable remote sensing variables that support the quantitative classification model, bridging the gap between satellite-derived variables and ecosystem degradation with explicit ecological links. We applied our degradation model to two case-studies, the mangroves of Rakhine State, Myanmar, which are severely threatened by anthropogenic disturbances, and Shark River within the Everglades National Park, USA, which is periodically disturbed by severe tropical storms. Our model suggested that 40% (597 km2) of the extent of mangroves in Rakhine showed evidence of degradation. In the Everglades, the model suggested that the extent of degraded mangrove forest increased from 5.1% to 97.4% following the Category 4 Hurricane Irma in 2017. Quantitative accuracy assessments indicated the model achieved overall accuracies of 77.6% and 79.1% for the Rakhine and the Everglades, respectively. We highlight that using an ecological conceptual model as the basis for building quantitative classification models to estimate the extent of ecosystem degradation ensures the ecological relevance of the classification models. Our developed method enables researchers to move beyond only mapping ecosystem distribution to condition and degradation as well. These results can help support ecosystem risk assessments, natural capital accounting, and restoration planning and provide quantitative estimates of ecosystem degradation for new global biodiversity targets.

Abstract:
Research Highlights: This is the first approach that integrates biodiversity data into Mapping and Assessment of Ecosystem and their Services (MAES) implementation and natural capital accounting process, at the national scale, using an extensive vascular plant dataset for Greece. Background and Objectives: The study aims to support the MAES implementation in Greece, by assessing, as a pilot, the woodland and forest ecosystem type; the targets of the study are: (a) Identify and map ecosystem type extent; (b) identify ecosystem condition using biodiversity in terms of plant species richness (i.e., total, ecosystem exclusive, endemic, ecosystem exclusive endemic diversity); (c) develop ecosystem asset proxy indicators by combining ecosystem extent and ecosystem condition outcomes; (d) identify shortcomings; and (e) propose future steps and implications for the MAES implementation and natural capital accounting, based on biodiversity data. Materials and Methods: Following the national European Union’s and United Nations System of Environmental Economic Accounts-Experimental Ecosystem Accounting (SEEA-EEA) guidelines and the adopted National Set of MAES Indicators, we developed a set of four proxy ecosystem asset indicators to assess ecosystem types with respect to ecosystem area extent and ecosystem condition. This was as interpreted by its plant diversity in terms of species richness (total, ecosystem exclusive, endemic, and ecosystem exclusive endemic diversity). Results: The results revealed that when indicators use well-developed biodiversity datasets, in combination with ecosystem extent data, they can provide the baseline for ecosystem condition assessment, ecosystem asset delineation, and support operational MAES studies. Conclusions: The relation among biodiversity, ecosystem condition, and ecosystem services is not a linear equation and detailed, fine-scale assessments are needed to identify and interpret all aspects of biodiversity. However, areas of importance are pinpointed throughout Greece, and guidance is provided for case-study selection, conservation strategy, and decision-making under the perspective of national and EU environmental policies.

Abstract:
The coral reef ecosystem has a significant physical and biological function and is also one of the coastal ecosystem components apart from the seagrass and mangrove ecosystem. Besides their ecological function, the coral reef also has an economic function. The condition of the coral reef ecosystem in Malalayang Beach has been changing for years. The utilization of remote sensing images can monitor current conditions. This research aims to map the coral reef ecosystem mapping in Malalayang Beach, Manado and conduct a test for the accuracy of coral reef ecosystem mapping using field survey data as a classification and validation sample. PlanetScope multispectral image has four channels to detect underwater objects: red, green, blue and near infrared. PlanetScope level 3B image for the research has a surface reflectance value for its pixel. The image processing stages of this research consist of sunglint correction, water column correction, and then continue to classify the coral reef ecosystem using random forests algorithm. Classification and accuracy training sample data were obtained using the photo transect technique. The sunglint correction regression equation is between 0.27 – 0.38. The coefficient of attenuation ratio in B1 is 0.927797938, B2 is 0.168841585, and B3 is 0.29033029. This value then becomes the input for the Lyzenga formula. The classification accuracy for level one using random forests is 72,54%, and the accuracy for level two mapping is 37,61%.Keywords: Coral Reef Ecosystem, Planetscope, Random Forests

Abstract:
The assessment and mapping of ecosystems and their services is considered an important action that effectively contributes to proper understanding of how ecosystems support human well-being, and furthermore &amp;ndash; to promote the sustainable use of natural resources. The diversity of cultural landscapes, especially in mountain areas, is a significant prerequisite for a variety of cultural ecosystem services that are valuable for the society. This evaluation is the basis for environmental management practices and policymaking. The study presents an approach for assessment and mapping of cultural ecosystem service (CES) &amp;ldquo;Cultural heritage&amp;rdquo; that is recognised as important and is provided by mountain protected areas (PAs) in &amp;ldquo;Pirin&amp;rdquo; National Park. The data from the Management Plan of &amp;ldquo;Pirin&amp;rdquo; NP were used for characterization and biophysical assessment of the condition of forest ecosystems and their potential to provide CESs. The analysis of the results revealed that the conservation regime allowed the territories to preserve a high degree of naturalness and a very good ecological condition as 94.80% of forest ecosystems are assessed with score 4 &amp;ndash;&amp;ldquo;good&amp;rdquo; condition and 0.44% are with &amp;ldquo;very good&amp;rdquo; condition &amp;ndash; score 5. The majority of forest ecosystems with &amp;ldquo;very good&amp;rdquo; ecological condition are Pinus peuce forests, located mainly on the territory of the reserves &amp;ldquo;Bayuvi Dupki- Dzhindzhiritsa&amp;rdquo; and &amp;ldquo;Yulen&amp;rdquo;, proving the importance of the protective regime of the territories. Forest ecosystems with average and high capacity to provide ES &amp;quot;Cultural heritage&amp;quot; prevailed, which is consistent with well-preserved and unique nature, the diversity of landscapes, and species richness. Considerable areas were assessed with score 5 &amp;ndash; very high capacity, mostly on the territory of the reserves &amp;ldquo;Bayuvi Dupki- Dzhindzhiritsa&amp;rdquo; and &amp;ldquo;Yulen&amp;rdquo;, and at the foothill of the huts.

Abstract:
To study climate impacts, data integration from heterogeneous sources is imperative for long-term monitoring in data sparse areas such as the High Mountain Ecosystems in the Rila Mountain, Bulgaria—difficult to both access and observe remotely due to frequent clouds. This task is especially challenging because discerning trends in vegetation location, condition and functioning requires observing over decades. To integrate the existing sparse data, we apply the Whole System framework adapted nationally in the Bulgarian Methodological Framework for Mapping and Assessment of ecosystem services. As the framework mainly relies on field data, we complement it with remote sensing vegetation indices (NDVI, NDWI and NDGI) for 42 years, together with Copernicus High Resolution Layer products and climate change reanalysis data for 40 years. We confirmed that the Whole System framework is extensible and semantically, ontologically and methodologically well suited for heterogeneous data fusion, co-analysis, reanalysis and joint interpretation. We found trends in ecosystem extent and functioning, in particular species composition, in line with climate change trends since around 1990 and exclusively attributable to climate change since 2015. Furthermore, we specified a data crosswalk between habitats and ecosystems at Level 3 (ecosystem subtype), and define new candidate indicators suitable for remotely monitoring climate change’s effects on the ecosystems’ extent and condition, as candidates for inclusion in the methodological framework.

Abstract:
Socio-ecological dynamics affect the ecosystem services supply and are relevant to generate effective water management strategies; this condition is considered to evaluate under a holistic approach, the water ecosystem services (WES) in an Andean supply basin (ASB) in Colombia. This analysis focus on the connection of biophysical and sociocultural components for the multi-purpose use of water based on The Soil and Water Assessment Tool (SWAT) modelling for Las Piedras River Basin (LPRB). The generated Hydrological Response Units (HRUs), allows to estimate the capacity of the basin for supplying water (quantity) in adequate conditions (quality) for local populations in rural and urban areas, as well as WES zoning. The model was calibrated and validated to generate a baseline scenario, which was complemented with social cartography and participative workshops. The results indicate a low concentration of nitrogen and phosphorus, boosted by specific agro-ecological strategies developed by local communities; however, there are health risks for populations downstream and those that are supplied with water directly from the source. Additionally, Land Use and Land Cover (LULC) affects water availability, which demands restoration and conservation strategies to maintain WES supply for socioeconomic and cultural purposes, since different views on the available WES converge in the basin.

Abstract:
Land Cover monitoring is an essential task for a better understanding of the ecosystem’s dynamicity and complexity. The availability of Remote Sensing data improved the Land Use Land Cover mapping as it is routine work in ecosystem management. The complexity of the Mediterranean ecosystems involves a complexity of the surrounding environmental factors. An attempt to quantitatively investigate the interdependencies between land covers and affected environmental factors was conducted in Nisos Elafonisos to represent diverse and fragile coastal Mediterranean ecosystems. Sentinel-2 (MSI) sensor and ASTER Digital Elevation Model (DEM) data were used to classify the LULC as well as to draw different vegetation conditions over the designated study area. DEM derivatives were conducted and incorporated. The developed methodology is intended to assess the land use land cover for different practices under the present environmental condition of Nisos Elafonisos. Supervised classification resulted in six different land cover clusters and was tested against three different environmental clusters. The findings of the current research pointed out that the environmental variables are independent and there is a vertical distribution of the vegetation according to altitude.

Abstract:
Mangrove forests face significant pressure due to human activities such as illegal logging, land conversion, and pollution. The impact of human activities on this ecosystem has raised concerns about the degradation and loss of mangrove forests. This study aimed to analyze the condition of the mangrove ecosystem on Pannikiang Island through density and area analysis. Data was collected using remote sensing methods, such as Sentinel-2 satellite imagery, which has a spatial resolution of 10 meters. The instruments used include PC hardware, ENVI, and ArcGIS software for image processing. This type of research is quantitative descriptive research that utilizes remote sensing technology. The research subjects were all mangrove forests along Pannikiang Island with a total area of 1,042,261.12 m². The analysis method used is the application of the NDVI algorithm. The main result of this research is that the condition of mangrove density on Pannikiang Island starts from the shallow density class to the very high-density class. Each density class has a different area, each starting from very low density with an area of 49137.98 m², low density with an area of 41947.12 m², medium density with an area of 65916.9 m², high density with an area of 175578.60 m², and very high density with an area of 749854.47 m². This research concludes that mangrove density conditions on Pannikiang Island have five density classes ranging from very low to very high density. This study has important implications for the management and protection of mangrove areas.

Abstract:
Mountain ecosystems play an essential role in sustainable mountain development, providing benefits and values to humanity not only for the rich biodiversity they contain, but also because of their important role in climate regulation, water cycle, provisioning of recreation, tourism, cultural or spiritual values. The high biodiversity of the mountain areas allow the provision of a wide range of ecosystem services. However, different impacts to the environment threaten the delivery of these services and, consequently, the quality of life of people, both living in the mountains and outside the mountains. Recognizing, demonstrating and capturing the value of ecosystem services can play an important role in setting policy directions for ecosystem management and conservation and, thus, in increasing the provision of ecosystem services and their contributions to human well-being. Quantifying and mapping of these benefits can also help managers and decision makers to realize the importance of these sites for conservation and to allow the proper understandings of the impacts of mountain forest ecosystems on territorial development and welfare of local populations. The paper aims to outline the relevance and applicability of the ecosystem services approach for the assessment of the condition of mountain ecosystems and the services, they provide, for better understanding by the scientific community and to support decision makers in sustainable management of mountain regions.

Abstract:
One of the most acute modern problems is the anthropogenic and general climatic degradation of natural ecosystems, including the transformation of water bodies of various origins. The regulation of large and small rivers, the change of their channels, and the management of the discharge regime are only part of the problems of a hydrological nature. The shallowing of large reservoirs leads to their excessive heating, which, in turn, changes the oxygen-carbon dioxide clearance due to the lower solubility of oxygen under heating conditions. The explosive growth of the simplest flora, caused by better warming and solarization, leads to the transformation of algosinusions, the building of new biocenotic relationships, and the formation of new communities. The influx of man-made, agricultural, and economic pollutants, in turn, causes a decrease in biodiversity in reservoirs, the accumulation of hazardous substances in ecosystem elements, and their migration along trophic levels. It is the small, often temporary, watercourses of girder origin that play an important role in these processes, replenishing a large, integrating object throughout its course. The runoff collected from the surrounding landscapes forms the primary toxic profile of small hydroelectric facilities, which initially affects their ecosystems and, at the same time, changes as a result of biotic transformation. Therefore, it is natural to talk not just about the quantitative trend of pollutants entering as a solution from small rivers into large ones but also about the ecosystem impact of these streams on the overall lothian ecosystem of a large river. Thus, during monitoring, it becomes necessary to consider the sequential transformation of an integral large river ecosystem under the influence of merging small river ecosystems that collect, transform, and transfer negative pressure to the surrounding and forming landscapes. That is why we come to the need to visualize numerical indicators in cartographic terms, which brings us closer to interactive GIS and accumulating and processing actual ecomonitoring material. The article analyzes the state of aquatic ecosystems in the southern part of the Volgograd agglomeration and the water quality indicators of a large water body depending on the state of the small watercourses feeding it. The analysiswas carried out on the basis of long-term observations using bioindication methods such as the Mayer index and the Woodiwiss index. The field analysis of chemical indicators of the quality condition was carried out using the test system “Cristmas.” With the help of mapping, the results of observations, the water quality by individual indicators, as well as the influence of small watercourses on the state of a large integrating aquatic ecosystem, were displayed.

Abstract:
Mangrove ecosystems consist of tropical plants that have adapted to the salinity, tidal fluctuations, and loose soil condition. Identification of mangrove ecosystems can be carried out by direct survey methods or by utilizing remote sensing technology. This study aims to map the area, percent cover, and density of mangroves in Makassar City using Sentinel 2A Imagery. The method used is the NDVI transformation, followed by Unsupervised-ISODATA classification, ground check with the 10 x 10-meter plotting method, and hemispherical photography. The results showed that the existence of mangroves in Makassar City was still found in the Tallo and Biringkanaya districts, with 68.81 ha of mangrove ecosystem cover area in the range of 84.36 - 91.89% (dense category). Likewise, the vegetation index based on NDVI analysis ranged from 0.73 - 0.81 (dense category), and the species density was in the range of 2700 - 6400 trees/Ha (dense category). Sentinel-2A imagery transformed with NDVI can be used to track mangrove areas and their density. The wide distribution of mangrove ecosystems in Makassar is relatively small but has good conditions.

Abstract:
A systematic approach to map and assess the "maintenance of nursery populations and habitats" ecosystem service (ES) (hereinafter called "habitat maintenance") has not yet emerged. In this article, we present an ecosystem service framework implementation at landscape level, by proposing an approach for calculating and combining a series of indicators with spatial modelling techniques. Necessary conceptual elements for this approach are: a) ecosystem condition, b) supply and demand of the targeted ecosystem service and c) spatial relationships between the Service Providing Units (SPU) and the Service Connecting Units (SCU). Ecosystem condition is quantified and mapped based on two indicators, the Biodiversity State and the Anthropogenic Impact. Quantification and mapping of supply and demand are based on the hypothesis that high supply can be activated in strictly protected areas and that a demand is localised in the Natura 2000 sites (N2K), considering them as the Service Benefit Areas (SBA). Wetlands are assessed as SCU between the SBA and the landscape areas where the habitat maintenance ES is supplied. By assessing wetlands as SCU, we intent to highlight their role as biodiversity stepping stones and as green infrastructures. Overall, we conclude that the EU biodiversity policy demand for no net loss and for a coherent N2K network can be met by enhancing the delivery of the habitat maintenance ES. This approach can assist policy-makers in prioritisation of conservation and restoration targets, in line with the EU biodiversity strategy to 2020 and the preparation of the post-2020 Strategy.

Abstract:
There is a broad diversity of concepts and methods used in ecosystem service (ES) mapping and assessment projects with many open questions related to the implementation of the concepts and the use of the methods at various scales. In this paper, we present a regional ES mapping and assessment (MAES) study performed between 2015 and 2017 over an area of ~900 km<sup>2</sup> in Central Romania. The Niraj-MAES project supported by EEA funds and the Romanian government aimed at identifying, assessing and mapping all major ES supplied by the Natura 2000 sites nested in the valleys of the Niraj and Târnava Mică rivers amongst the foothills of the Eastern Carpathians. Major ES in this culturally and ecologically rich semi-natural landscape were determined and prioritised in cooperation with local stakeholders. Indicators for the capacities of individual services were modelled with a multi-tiered methodology, relying on the involvement of regional thematic experts. ES with appropriate socio-economic data were also evaluated economically. The whole process was supervised by a stakeholder advisory board endowed with a remarkable decision-making position, giving feedback and recommendations to the scientists at the critical nodes of the process, thus ensuring salience and legitimacy. In addition to simply presenting the dry facts about the approaches (assessment targets, methods) and outcomes, we also identify several key decisions on the design of the whole assessment process related to (1) the role of conceptual frameworks, (2) stakeholder involvement, (3) the selection of ES to assess (priority setting), (4) the development of models and indicators and (5) the interpretation of outcomes, for which we give a detailed description of the decision process. We found that conceptual frameworks can have a pivotal role in structuring and facilitating communication amongst the participants of a MAES project and that a broad and structured involvement of stakeholders and (local) experts creates a sense of ownership and thus can facilitate local policy uptake. We argue that priority setting and the development of indicators should be an iterative process and we also give an example how such a process can be designed, enabling an efficient participation of a broad range of experts and the collaborative development of simple ES models and indicators. Finally, we discuss several general issues related to the interpretation of results of any kind of MAES and the follow-up of regional MAES projects.

Abstract:
Formulation of the problem. Ecosystem services are resources and benefits that modern humanity can receive from the nature. It is the material benefit from abiogenic and biogenic components of various natural ecosystems. There were not large-scale studies according of evaluation ecosystem services in the Ukrainian water area of the Black Sea before, it is the actual environmental and socio-economic problem. Review of previous publications. The main approach to evaluating the state of ecosystems in the EU countries based on the choice of load indicators on the ecosystems and their mapping. Multi-level approach implies the next steps: detection and evaluation of services (indicators, borders, quantitative assessment); calculations and a demonstration of value (assessment in physical units and money equivalent); court fixation and solutions (tools - subsidies, taxes, payments for ecosystem services, etc.). Purpose. The man goal of the paper is analysis and estimation of modern state of ecosystem services, methods and perspectives of their using. Methods. The methodological basis of the study is the critical analysis of existing approaches to the assessment of ecosystem services of marine and coastal ecosystems. During the preparing of the paper published data had been used, as well as the materials of personal research on various aspects of the evaluation of ecosystem services of the Northwestern part of the Black Sea. Results. Marine and coastal ecosystems play a critical role in providing key services such as food supply, sequestration of anthropogenic carbon, waste management, biological regulation and the provision of habitat for hydrobionts. However, along with other ecosystems, today they are under serious anthropogenic pressure. Some types of anthropogenic activities have a very negative effect to the condition of natural ecosystems and to receive of their services. The ecosystems of the Northwestern part of the Black Sea are the living place of numerous organisms. These ecosystems consist on supporting services. Important regulatory services provide wetlands protected by the Ramsar Convention. The most intense cycle of nutrient substances occurs in the river’s mouth areas. The marine environment absorbs, disinfects and processes all sorts of waste production and consumption. Conclusions. Take into account of the limited information of the of ecosystem services under the Northwestern part of the Black Sea, the first task is to determine the needs of local populations for these services, collection and generalization of information about their condition, coordination of their assessment methods for the region and the evaluation itself.

Abstract:
The Anambas Islands is located in the Natuna Sea - the southern part of the South China Sea, encompassing vital marine ecosystems. Among these ecosystems, the mangrove stands out as crucial in the Anambas, playing an important role in providing a range of ecosystem services. However, spatial information regarding the condition of this ecosystem is very limited. In this study, our focus was on estimating and mapping the aboveground biomass (AGB) of mangroves across the Anambas using a combination of field survey and satellite remote sensing data. We employed seven vegetation indices along with five regression methods to determine the most suitable combination for producing an AGB. Our findings revealed that the incorporation of Sentinel-2 remote sensing images and field survey data can be used to model the AGB. The best combination model was the Modified Soil Adjusted Vegetation Index (MSAVI) and polynomial regression, achieving an accuracy of 72.09%. Anambas was estimated to possess a potential AGB of 369,371.47 tonnes and a carbon stock of 173,604.59 tonnes. These findings provide valuable information for regional conservation strategies, including the identification of protected zones, the establishment of a baseline for mangrove conditions, and the assessment of carbon credit in the Anambas.

Abstract:
The vitality of the Great Barrier Reef (GBR) is threatened by many human-made impacts. Monitoring this ecosystem makes it possible to study the general condition and the health of the GBR. However, due to the large extent of the GBR and limited accessibility in the ocean environment, mapping and monitoring this ecosystem has been always challenging task and connived. In this regard, Remote Sensing (RS) is an effective technique that provides valuable information for mapping and monitoring this ecosystem. In an attempt to monitor the GBR, this article applied a supervised machine learning algorithm to classify the Landsat 8 imagery collected over the GBR. To this end, the spectral responses of coral reefs, shallow water, deep ocean, rocks and sands, and green alga were initially determined from the satellite images. This information was then ingested to the Maximum Likelihood supervised classifier to map coral reefs in the GBR. Additionally, this study discusses how the GBR has been affected by anthropogenic disturbance. The results provide confirmatory evidence that RS techniques present great promise as a means of mapping coral reefs and monitoring their general conditions. We used the ambiguity matrix and validation data to estimate the accuracy of the proposed method. Overall, the proposed method was able to identify 5 different classes considered in this article with an average accuracy of 90%.

Technological developments, especially in remote sensing in mangrove mapping are growing. One of them is the use of Unmanned Aerial Vehicle (UAV) as a vehicle for capturing aerial photo data. This study aims to map the mangrove ecosystem in order to find out spatial information with UAV technology and to identify mangrove species, distribution, and associations. The ground survey was conducted on 02 until 04 May 2019 in North of Lancang Island, Seribu Islands, DKI Jakarta Province. The mangrove data collection was carried out in four stations with marking, tracking the mangrove area and drone flights for taking aerial photo data. Based on the research, it was found that the mangroves were in good condition with an area of around 4 hectares, consisting of Rhizophora mucronata. However, there is a lot of waste around the mangrove ecosystem, especially inorganic waste in the form of plastic. Where the presence of garbage can cover the roots of the mangrove so that it can affect respiration and cause death in mangroves. The application of UAV technology that is integrated with GIS in mangrove ecosystem mapping is expected to be an alternative in extracting mangrove databases for future coastal ecosystem management.

Abstract Tengin Baru is located in the development area of Indonesia Capital City (Ibu Kota Nusantara, IKN). The village covers a small part of the mangrove ecosystem in the region which currently utilised for other uses by the people. In order to implement a sustainable approach of the mangrove management, the involvement of the locals in mapping the land use of the village could produce a more aligned mapping with the latest social conditions and helps identify field issues. The mapping could also be used as the basis for the village development planning considering its strategic and important situation in the IKN area. The objectives of the study were to identify the mangrove cover and other land use in Tengin Baru Village and its issues. The results showed that most of the land is forest and mangrove covered around 134.17 hectares (2.2% of the village area) at the southern part of the village. The mangrove was dense and in good condition with one of the species (Nypa fruticans) harvested for making roofs. The issues regarding the village land use included the development of Sepaku Semoi Dam to supply water to IKN and the masterplan of the village as the centre for tourism and economic growth of the region. The village planned to protect mangrove and build fishing ponds for mangrove tourism attraction.

Abstract:
Protecting forests and maintaining their water conservation function has proven to be the most effective approach to generating and maintaining water quantity from the source to the end user. The water conservation and water regulating properties of forest ecosystems that are inherent in forested areas are an undervalued resource at the current stage. To turn this property into a source of income, it needs to be institutionalized as a production function of forest owners. This also defines the main aim of this research, namely to design and implement a system for mapping the territorial distribution and characteristics of sanitary protection zones in Bulgaria, which will help assess the condition and determine the value of ecosystems and ecosystem services. In this regard, this paper presents the approaches used to integrate and design the spatial data of the sanitary protection zones and the database of the forests in Bulgaria in a repository and the system created to visualize these data through different approaches.

Abstract:
Cempi Bay is an important water area with a rich and diverse ecosystem. One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.

Abstract:
The EU Biodiversity Strategy for 2020 was a driving force behind spatially explicit quantifications of Ecosystem Services (ES) in Europe. In Portugal, the MAES initiative (ptMAES–Mapping and Assessment of Ecosystem and their Services) was conducted in 2014 to address Target 2 (Action 5) of the Strategy, namely mapping and assessing ecosystems, ecosystems’ condition (EC), and ES. In this study covering the NUTS II Alentejo region, EC was assessed and mapped based on four indicators (soil organic matter, plant and bird diversity, and ecological value of plant communities) and five ES were assessed and mapped (soil protection, carbon sequestration, and fiber/crop/livestock production). Assessments were performed under a multi-tiered approach, ranging from spatialization of statistical data to analytical modeling, based on the most detailed land-use/land-cover cartography available. In this paper, we detail the methodological and analytical framework applied in ptMAES and present its main outcomes. Our goal is to (1) discuss the main methodological challenges encountered to inform future MAES initiatives in Portugal and other member states; and (2) further explore the outcomes of ptMAES by looking into spatial relationships between EC and ES supply. We highlight the advantages of the proposed analytical framework and identify constraints that, among others, limited the number of ES and EC indicators analyzed. We also show that MAES can provide useful insights to landscape planning at the regional scale, for instance, red-flagging areas where ES supply may be unsustainable over time.

Abstract:
Abstract Karimunjawa and Kemujan Islands are the largest islands in the Karimunjawa National Park which have a coral reef ecosystem. Coral reefs are influenced by the environmental conditions around them. Changes in environmental conditions, rising of sea surface temperatures, and human activities can pose threats. Coral reefs have important functions and roles in the balance of marine ecosystems, so monitoring coral reefs is very important. To develop coral reef conservation in the waters of Karimunjawa Island, a study was conducted to monitor the condition of coral reef cover using remote sensing. The purpose of this study was to determine changes around coral reefs in the waters of Karimunjawa Island and Kemujan Island in 2018 using Landsat 8 satellite imagery and to analyze changes in the area and condition of coral reefs in the waters of Karimunjawa Island and Kemujan Island, Karimunjawa National Park. This study uses a remote sensing method which begins with collecting Landsat 8 satellite imagery data, then continued with satellite image data processing with ENVI and ArcGIS 10.8 software using the Lyzenga algorithm for coral reef mapping. This method is more efficient and can cover a wide study area.

Abstract:
Ecosystem service and disservice components have a great impact on the environment as well as on urban life. The aim of the research is to assess the impact of ecosystem services and disservices by tracking the change over a span of 15 years (2005-2020) using satellite image analysis. It was conducted in wards 23 and 29 of Khulna City Corporation (KCC), an area adjacent to the river. The overall work breakdown has been rounded up in a methodological framework which cleaved into two parts focusing on ecosystem services, disservices and multispectral image analysis steps. Multispectral image analysis has been done using Normalized Difference Vegetation Index (NDVI) and Normalized Difference Build-up Index (NDBI). On the other hand, geospatial analysis has been done using Digital Elevation Model (DEM), Service Area Analysis (SAV) and other mapping tool including Geographic Information System (GIS) to show the changed impact of both ecosystem components. The study areas attain provisioning, habitat, cultural and regulatory service components and the disservice elements have been sorted out according to sources. Comparative study showed increase in the buildup area; vegetation coverage because of increasing vegetation, cultivation and gardening practices; good weather and water circulation condition and water body conservation which has significant positive impact on the area. The disservice component like poor drainage condition and solid waste management system and risky infrastructures have negative impact, need to address for the betterment of residence and environment.

Abstract:
The obligations of the EU Biodiversity Strategy 2020 are generating a need to create national maps and monitoring systems for the state of biodiversity and ecosystem services (ES) on the basis of indicators. The paper gives an overview of the ecosystem services indicators being developed for Germany in the context of ongoing research projects. Additionally, it provides the indicator specifications, which are aligned with the EU MAES framework concepts (initiative on Mapping and Assessment of Ecosystems and their Services). We illustrate aspects of data selection, calculation and negotiation procedures, results and target values in general and by way of examples. The German indicator-based approach presents measures and sums up ES in their spatial expression and temporal change and compares them with objectives. As far as possible, this is carried out according to the demand-supply concept. A prioritization of ES classes to be processed was carried out in the framework of an expert-based assessment. The results indicated that 21 of the 48 CICES classes (Common International Classification of Ecosystem Services) were most relevant for Germany in recent years. We proposed a total of 51 indicators, of which 14 indicators for 4 ES classes were accepted, implemented and published by the end of 2016. The development of ES maps and the indicator-based assessment on a national scale is a process. Consequently, the necessary further steps are shown.

Abstract:
There is broad subject that ecosystem service influence human well-being (HWB), however HWB are unmeasurable variable, therefore it still not been integrated fully into ecosystem service assessment and spatial planning document in Indonesia. Provision of sustainable ecosystem services, especially food provisioning, is a challenge for Bantul Regency as it faces huge production deficits because of land conversion and urbanization, therefore, it will threaten the condition of its human well-being. It aims to determine the distribution of human well-being conditions as well as analyzing which capital is the basic capital for human development in Bantul Regency. This study evaluates and maps human well-being by using Sustainable Livelihood Framework (SLF), based on perspective of experts and stakeholders, then analyzed the spatial variation on landscape by mapping the area, and discussed how to achieve human well-being conditions by maximizing services from the ecosystem. Questioners were distributed to stakeholders that involved in development decision making in Bantul regency in Likert scale, then it was analyze to determine the scores of each indicator in every capital. Then regional boundary shapefile analysis in ArcMap was carried out to map the level of conditions of human well-being. Based on the analysis, Human Capital is the largest capital in the people’s welfare of Bantul, the highest condition is located in the Dlingo and Srandakan Districts. However, financial, physical and social capitals are located in the same area, which makes the Banguntapan, Sewon and Bantul Districts have the best human well-being conditions in all of Bantul Regency. This study also found that besides geographical conditions play an important role in producing different types of ecosystem services, social-economic factors is the most important factor in determining the difference in value of each capital in human well-being. Optimizing planning regulation has to consider these spatial patterns.

Abstract:
Natural heritage (NH) possesses an outstanding universal value that can be described as "natural significance" at a national level. The ecosystems can be considered as the spatial units which represent the NH of the particular area in terms of their value to people. Recreation and tourism are amongst the important values which are strongly dependent on the NH and they have a certain impact on the ecosystems' condition and the quality of the services they provide. The efforts through the Mapping and Assessment of Ecosystems and thier Services (MAES) process led to the development of a multi-tiered approach that considers different methods at different levels of detail and complexity and can be applied according to specific needs, data and resource availability. In this paper, we propose the development of this methodology for the specific need for mapping and assessment of the NH as a source of ecosystem services (ES) for recreation and tourism. The conceptual scheme of the study demonstrates how the MAES framework can be adapted to the specific needs of the work and arrange the methods into three tiers according to the data availability and resources. The mapping and assessment procedure is based on an algorithm for spatial data analyses which enables the evaluation of the NH potential to provide 15 ecosystem services. The results show that the NH of Bulgaria is a valuable source of ES which are well presented in most parts of the country. The areas with very high potential form several clusters that correspond to the country's tourist regions. The proposed approach is applicable on the national scale and solves the problem of data availability limitations for various ES. The algorithm ensures the optimal quality of the results using the available data and resources. Instead of an expert-based assessment for all services which is easier, but less accurate, the proposed approach provides the means how to define more precise indicators, based on statistical data or models where possible. The study provides appropriate data for analyses of the methods' performance at different tiers.

This study aims to produce video mapping design concept to educate the topic on sea turtle conservation for all levels of Indonesian societies, especially in the Jakarta Aquarium recreation facilities. Indonesia, a tropical country with variety of natural resources and habitat of the endangered sea turtles required a protection on their habitat by the government. There are 6 types of sea turtles spread across the vast 138 different waters in Indonesia. Efforts of preservation as part of the world's ecosystem need to be done by various parties. The Visual Communication Design, as a major whom proficient in the perceptive communication language has a big role in delivering the message and exploring media for public education about the importance of maintaining the balance of the turtle ecosystem. Video mapping or projection art, is a contemporary technique of delivering information through visual images using lighting and projection so as to produce optical illusions on the object being directed. Through visual communication design method, the result is a video mapping design concept to display a provoking animation meant to visualize the grueling condition and survivability of sea turtles in recent years and to gain awareness for preserving and protecting the natural environment. The video mapping design concept can be used for environmental issues learning materials for youth.

Abstract:
The sustainable development goals (SDGs) for 2030 are established to address global challenges including environment and human well-being. The SDGs are interconnected and achievement of them requires consideration of the planet’s ecosystems and resources - land, water and air. Ecosystem services (ES) approach has a high potential for better planning, policy and decision making. Understanding how different ecosystems (e.g., forests, rivers, wetlands, grasslands) contribute to the social and economic benefits is critical to ensure the long-term biodiversity protection and sustainable use of ecosystems. A conceptual framework linking biodiversity and ecosystem condition (its structure and functions), and ES to human well-being has been well-established in EU by so called MAES process (Mapping and Assessment of Ecosystem Services) lead by the European Commission. The framework is applied in recent research studies and projects, as well as national MAES processes. Various methods are applied for MAES in terms to determine biophysical, economic and social values and to deliver integrated ecosystem assessment. Assessment of ES and trade off analysis shall provide a new perspective for land use planning and decision making at different administrative and spatial levels and in different sectoral policies. EU and national policies for instance on agriculture, fishery, forestry, climate should account the benefits provided by relevant ecosystems and to ensure that the values are not diminished but rather enhanced during the implementation of the policies. Terrestrial and water ecosystems are interconnected as land-based human activities creates pressure that impacts the conditions in water ecosystems and thus delivery of ES by rivers and lakes. For example, intensive agricultural land use produces food for people and income; however, the activity also most frequently causes problems with water quality and quantity in the catchment area and a loss of biodiversity. A risk of such trade-off shall be handled in policy development. Ecosystems also contributes to the resilience of communities by reducing the risk of natural hazards and mitigate adverse impacts. Regulating services such as flood control are substituting investments in flood protection ensured by forests, wetlands and grasslands instead of human built infrastructure. Appropriate land cover and land use shall serve as a basic flood protection measure. Natural processes are increasingly recognised to create new-type solutions that use and deploy the properties of natural ecosystems and their services in an “engineered” way. A wide range of measures called also as nature-based solutions provide another opportunity to work with nature towards global sustainability.

Abstract:
This study presents a standardized approach to collecting, registering, and reporting field-survey data for baseline MAES (Mapping and Assessment of Ecosystems and their Services) information in Greece. This is accomplished through a web-based platform (MAES_GR) exclusively developed under the relevant, nation-wide LIFE-IP 4 NATURA project. Based on the European Commission’s guidance for ecosystem condition (EC) and ecosystem services (ES) MAES studies, we conceptualized and structured an online platform to support EC and ES assessments, integrating all relevant fields of information needed for registering EC and ES parameters. A novel algorithm calculating EC was also developed and it is available as an integral part of the platform. The use of the MAES_GR platform was evaluated during nationwide field surveys efforts, increasing time efficiency and reducing costs. Field recording of EC and ES pinpoint spatial priorities for ecosystem restoration, conservation and sustainable development. This work highlights that MAES implementation can be favored by the use of technology tools such as mobile survey platforms, developed according to scientific needs and policy guidelines. Such tools, apart from the data inventory phase, can be used for data analysis, synthesis and extraction, providing timely, standardized information suitable for reporting at the local, regional, national and European Union scale.
