Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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 – 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) “Cultural heritage” that is recognised as important and is provided by mountain protected areas (PAs) in “Pirin” National Park. The data from the Management Plan of “Pirin” 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 –“good” condition and 0.44% are with “very good” condition – score 5. The majority of forest ecosystems with “very good” ecological condition are Pinus peuce forests, located mainly on the territory of the reserves “Bayuvi Dupki- Dzhindzhiritsa” and “Yulen”, proving the importance of the protective regime of the territories. Forest ecosystems with average and high capacity to provide ES "Cultural heritage" prevailed, which is consistent with well-preserved and unique nature, the diversity of landscapes, and species richness. Considerable areas were assessed with score 5 – very high capacity, mostly on the territory of the reserves “Bayuvi Dupki- Dzhindzhiritsa” and “Yulen”, and at the foothill of the huts.

Full textAbstract:
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.

Full textAbstract:
Large scale ecosystem restoration is an important societal issue because significant risks, costs, and benefits can accrue on large landscapes. It is important to understand baseline ecosystem conditions, existing condition, and to the extent possible estimate ecosystem response to alternative management scenarios. Incorporating ecosystem process and function into restoration planning and implementation will make ecosystem restoration projects sustainable. The Upper Mississippi River System is an excellent case study for such issues because it is an important, multiple-use ecosystem with significant ongoing investment in ecosystem, agri-system, and navigation system management.
Large-scale geomorphology, hydrology, and land cover information was compared among presettlement, contemporary, and potential future reference conditions to examine ecosystem state and evaluate mechanisms responsible for ecosystem condition. The UMRS was scaled by physiographically similar characteristics into large floodplain reaches several hundred river miles in length, geomorphic reaches 50 to several hundred miles, and a mile-by-mile segmentation of the river floodplain extent. Ecologically relevant geomorphic classes were devised from existing data and evaluated by river reach to characterize presettlement geomorphology, and dams and levees were superimposed to reflect the altered hydrogeomorphology of the contemporary ecosystem. A pre- and post-impact Indicators of Hydrologic Alteration river stage analysis evaluated dam impacts, and pre-dam and post-dam aquatic habitat class distribution was compared. A floodplain inundation simulation analysis provided new information on the potential spatial distribution of frequent floods. Land cover data available for presettlement and modern reference periods were compared at several spatial scales. Multivariate analyses evaluated land cover characteristics among geomorphic reaches, as well as to assess the influence of hydrogeomorphic drivers on land cover for presettlement and contemporary reference periods.
The objective of this research was to clearly delineate the divergence of environmental conditions among reference periods to evaluate which drivers need to be, and can be, altered to change ecosystem state. Hydrogeomorphic response to development indicates several restoration objectives that are appropriate system-wide and others that are best suited to specific river reaches. Similar data sources are available for much of the rest of the United States through the Public Land Survey and engineering surveys of any significant civil works projects.

Full textAbstract:
A deficiency in crucial digital data, such as vegetation cover, in remote regions is a challenging issue for sustainable water management and planning, especially for areas undergoing rapid development, such as mining in the Pilbara, Western Australia. This is particularly relevant to Inflow and Groundwater Dependent Vegetation (IGDVs) (riparian vegetation and groundwater dependent vegetation) which provide important ecological services and, as such, require regional protection. However, such invaluable assets experience changes over time due to either human activities such as land development or natural phenomena such as climate change or fire events.
The main objectives of this research was to 1) advance an approach to delineate inflow dependent ecosystems at a local scale; 2) adopt it to map the assets at regional scale using remotely sensed data (Landsat 5 TM imagery due to its appropriate temporal and spatial resolution for historical studies, 1986-2011), ground-truth data and available information such as reports, digital layer and climate data; 3) develop a method for identification and quantitative assessment of IGDVs changes and attribution of the changes to particular impacts or stressors, and 4) apply the developed change detection method to investigate and evaluate impacts of an adopted water resource management options on inflow dependent assets in the Pilbara.
Outcomes of the research exposed that the proposed delineation method allowed production of accurate inflow dependent ecosystems maps for the Pilbara bioregion. The change detection method was also effective in detecting various spatial and temporal scales of changes and separating anthropogenic and natural impacts. It was further discovered that climate has had significant impacts on the assets of the area.
The finding and information produced from this research is capable to aid government, industry and communities to consider the environmental, social, cultural and economic aspects of the sustainable use, development and management of land and water resources in arid and semiarid Pilbara, WA and areas with similar ecohydrological conditions. Four papers were prepared from the research, two are published and two are under review.

Full textAbstract:
AbstractRice is a staple food for more than half of the global population. With the increasing population, the yield of rice must correspondingly increase to fulfill the requirement. Rice is cultivated worldwide in four different types of ecosystems, which are limited by the availability of irrigation water. However, water-limiting conditions negatively affect rice production; therefore, to enhance productivity under changing climatic conditions, improved cultivation practices and drought-tolerant cultivars/varieties are required. There are two basic approaches to cultivation: (1) plant based and (2) soil and irrigation based, which can be targeted for improving rice production. Crop plants primarily follow three mechanisms: drought escape, avoidance, and tolerance. Based on these mechanisms, different strategies are followed, which include cultivar selection based on yield stability under drought. Similarly, soil- and irrigation-based strategies consist of decreasing non-beneficial water depletions and water outflows, aerobic rice development, alternate wetting and drying, saturated soil culture, system of rice intensification, and sprinkler irrigation. Further strategies involve developing drought-tolerant cultivars through marker-assisted selection/pyramiding, genomic selection, QTL mapping, and other breeding and cultivation practices such as early planting to follow escape strategies and decreasing stand density to minimize competition with weeds. Similarly, the identification of drought-responsive genes and their manipulation will provide a technological solution to overcome drought stress. However, it was the Green Revolution that increased crop production. To maintain the balance, there is a need for another revolution to cope with the increasing demand.

Full textAbstract:
Mapping of protective functions and effects of forests is subject to geodata on 1) natural hazard susceptibilities (hazard potential), 2) assets to be protected (damage potential), and 3) forest conditions, that is, forest use (legal extent) and cover (structure). Objectives in terms of legal definitions of assets and levels of risk acceptance (protection targets) as well as on the necessary and guaranteed reliability of the map products determine the mapping scale and the requirements for the methods and input data to be used. However, applied definitions of protection targets are often missing in the legislative bases and mapping approaches must rather be adapted to the existing geodata, their conceptual data model and quality, than simply using existing methods. Agreeing on the assets to be protected and the quality of their digital representation in terms of spatial resolution, positional accuracy, currentness, topological consistency, and entities is crucial for mapping object protective forests. The reliability of assessing protective effects of forests for large areas based on information acquired with remote sensing techniques depends on the temporal match, spatial and spectral resolutions, and limitations in representing current forest conditions by spectral and elevation data.

The aim of this chapter is to add to existing knowledge and theory relating international labour migration under conditions of free movement. The chapter focuses on Polish nationals who, with Lithuanians, are the largest immigrant group in Ireland from the eight countries of Central and Eastern Europe that acceded to membership of the European Union (EU) in 2004. The research draws on census of population data at a range of geographical scales. The movement of the immigrants between areas was traced using choropleth mapping and statistical measurement of population density and distribution, compared with the Irish population, using the Hoover Index and the Dissimilarity Index. The greatest concentration of Polish nationals occurs in large centres of population but movement took place to smaller places from the beginning and increased over time.

Full textAbstract:
Synthetic aperture radars (SARs) propagate and measure the scattering of energy at microwave frequencies. These wavelengths are sensitive to the dielectric properties and structural characteristics of targets, and less affected by weather conditions than sensors that operate in optical wavelengths. Given these advantages, SARs are appealing for use in operational crop growth monitoring. Engineering advancements in SAR technologies, new processing algorithms, and the availability of open-access SAR data, have led to the recent acceleration in the uptake of this technology to map and monitor Earth systems. The exploitation of SAR is now demonstrated in a wide range of operational land applications, including the mapping and monitoring of agricultural ecosystems. This chapter provides an overview of—(1) recent advancements in SAR systems; (2) a summary of SAR information sources, followed by the applications in crop monitoring including crop classification, crop parameter estimation, and change detection; and (3) summary and perspectives for future application development.

State-of-the-art tools are revolutionizing protected area (PA) manager approaches to biodiversity monitoring. Effective strategies are available for test site establishment, data collection, archiving, analysis, and presentation. In PAs, use of new technologies will support a shift from primarily expert-based to automated monitoring procedures, allowing increasingly efficient data collection and facilitating adherence to conservation requirements. Selection and application of appropriate tools increasingly improve options for adaptive management. In this chapter, modern biodiversity monitoring techniques are introduced and discussed in relation to previous standard approaches for their applicability in diverse habitats and for different groups of organisms. A review of some of today’s most exciting technologies is presented, including environmental DNA analysis for species identification; automated optical, olfactory, and auditory devices; remote sensing applications relaying site conditions in real-time; and uses of unmanned aerial systems technology for observation and mapping. An overview is given in the context of applicability of monitoring tools in different ecosystems, providing a theoretical basis from conceptualization to implementation of novel tools in a monitoring program. Practical examples from real-world PAs are provided.

Full textAbstract:
In the rapidly evolving landscape of supply chain (SC) management, the importance of tracking services in overseeing the lifecycle from production to sale cannot be overstated. These services rely on sophisticated systems that monitor vital condition information such as temperature and humidity. However, beyond the technical and mechanical aspects, human factors play a critical role in the operational integrity of these systems. This paper introduces a novel risk assessment methodology for SC tracking, emphasizing human error alongside technological and security risks, and integrates motivation and contribution aspects into the SC risk assessment framework.Our methodology is comprehensive, exploring the strategic business and technical requirements of SC tracking systems. It uniquely extends to assess the frequency, nature, and impact of human errors, alongside considering technological aspects. We investigate how human factors interact with elements such as IoT, cloud services, and standard IT systems, potentially leading to security vulnerabilities and operational inefficiencies. By mapping these human-centric risks to key operational components, we provide a comprehensive view of potential threats in SC tracking.In an environment where standardization efforts in SC risk assessment methodologies are ongoing, our work identifies the necessity for more specialized techniques, particularly those addressing security risks related to tracking and monitoring systems. Given the distributed nature and internet connectivity of these systems, they are inherently susceptible to numerous security challenges, predominantly involving their technological equipment. This underscores the imperative for a targeted risk assessment methodology focusing on the security risks of SC tracking systems, particularly in the context of traceability services and the monitoring of the state of assets in transit.Employing well-known risk assessment standards and threat modeling guides, our methodology scrutinizes targeted IT components used in SC tracking systems, their technical characteristics, and realistic threat agents in the SC ecosystem. We aim to evaluate whether security attacks originating from SC-specific threat agents result in tangible security risks against targeted hardware and software components within SC networks.To validate our methodology, we present a proof of concept application based on a real-case scenario. This demonstration highlights the versatility of our methodology to accommodate various SC scenarios, such as food, pharmaceuticals, and cold supply chains. The primary advantage of our proposed methodology lies in its ability to integrate risk estimation with the technological attributes of typical SC tracking systems and their operational requirements, which may vary based on the type of goods and services involved.In conclusion, this paper addresses the broader challenges in developing and implementing smart SC tracking systems, with a special emphasis on the integration of human error in these technologically advanced environments. We underscore the significant influence of human factors on the reliability and security of SC tracking systems and the cost implications and potential operational disruptions caused by human factors, thereby highlighting their pivotal role in the overall effectiveness and security of SC ecosystems.

Full textAbstract:
Water and sediments in coastal areas interact at different scales, thus shaping the marine environment and providing physical habitat for ecosystems. Hence, the hydromorphological conditions represent a key aspect of aquatic ecosystems considered in the Water Framework Directive as supporting quality elements (alongside the physicochemical), which are expected to provide the boundary conditions for the biological quality elements. Any alteration in those can reshape the corresponding biological conditions at various spatial and time scales. The Directive states that coastal waters might be subdivided considering significant changes in bathymetry, substrate, or exposure. Typologies established by the Directive should reflect the natural variability in hydromorphological characteristics and processes. Therefore, the aim of the present study is to establish the type-specific hydromorphological reference conditions by identifying areas within water bodies that are relatively homogeneous from a hydromorphological point of view in order to better serve both determination and management of environmental state and designation of highly modified coastal waters based on a set of clear quantitative criteria. The data employed comprise remote bathymetry measurements, sediment mapping and wave exposure type. These layers were geospatially analysed to differentiate aquatic areas of similar hydromorphological conditions. About 100 such areas were delineated, in which conditions could be considered reference. At the same time, analysis revealed eighteen modified smaller scale areas, within the above-mentioned ones, which are considered hotspots of hydromorphological change in anthropogenically modified environment; hence, an object of future monitoring and specific management actions.

Abstract Offshore wind developers obtain extensive geophysical, geotechnical, and habitat data during Site Characterization activities. Integration and delivery of this information to a diverse group of stakeholders and Government agencies is required. We present an integrated benthic habitat mapping approach tailored to regional geology and ground conditions and discuss how various data was utilized to deliver multiple components of the permitting process. Multiple data sets were integrated and presented via a web-based GIS platform to aid delivery, visualization, and communication. Our unified approach to benthic habitat mapping and delivery of products to stakeholders was instrumental in successfully coalescing multiple performers to develop their individual deliverables in a cohesive and rapid manner. This approach reduced risk to schedule and budget, without sacrificing data density or quality. Four annual (2019–2022) benthic surveys were acquired to support Site Characterization and subsequent permitting processes. High-Resolution Geophysical data were collected concomitantly with the 2020 benthic survey data and used to refine subsequent 2021 and 2022 benthic survey designs. Benthic survey data consisted of grab sample tests (grain size), macrofaunal taxonomy, sediment profile and plan view imagery (SPI-PV), video imagery from each grab station, and towed video transects. Acoustic data products were processed and interpreted to create polygons of seafloor sediment coverage over the ASOW study area and ground-truthed with physical sampling, video, and digital still imagery to refine and validate acoustic data into a mappable model of essential fish and benthic habitats. Seafloor morphology and seabed sediment interpretations were coalesced into a benthic habitat model that displayed substrates consisting mostly of mobile sand sheets, with interspersed areas of gravelly sand and discrete patches of gravel. Overlying the substrate model was a range of benthic features and morphologies, including sand ridges, sand waves, megaripples, ripples, areas of depressional marks, hummocky seafloor, interbedded surficial sediments, irregular seafloor, and localized relief features. From these data, classified maps of Coastal Marine Ecological Standard (CMECS) substrates and fish habitats were made. Additional CMECS classification of benthic biotic components were mapped, showing the taxonomic communities that are present in each substrate. Seabed sediment modeling and morphological trends were dynamically studied and compiled into an interpreted and GIS-friendly dataset that enabled rapid online transfer to subject matter experts tasked with quantifying the benthic ecosystem across the development area. The methods and modeling that were produced by expert refinement of geophysical data to reflect the physically observed habitat structures allowed for dynamic minimum mapping unit variability while also isolating and identifying key areas of interest for benthic researchers and regulators. This mapping process led to an efficient and unified approach for all teams, saving project time and expense.

The Illinois School of Architecture is committed to developing students with an informed worldview through global and local engagement.1 These opportunities form students with a truly global and social perspective on architecture and the built environment, a critical quality of tomorrow’s design professionals. According to the master’s program main objective, students should learn to analyze complex environments and propose innovative design solutions to the world’s most urgent problems. This paper will focus on an academic exercise that challenged traditional mapping methodologies and embraced science and big data towards more creative collaborative processes. Within the aesthetics of remote collaboration, this experiment on map-making inverted the technicality of drawing, challenging the participants to map, model, and represent an expanded worldwide view of the mangrove ecosystem. The study of coastal cities has been traditionally conditioned to a Eurocentric vision of space, where the importance of the metropolis and its infrastructure is imposed over the singularities of the people’s relationship with landscape and nature. Coastal cities in the West Africa and The Caribbean are potential laboratories of climate adaption for building and social space. However, its study and analysis have not called upon cross-disciplinary approaches to develop conceptual and methodological frameworks between natural, cultural and social scientists. “The mangrove is in fact a sensitive figure in our collective consciousness; it is in our nature, a cradle, a source of life, of birth and rebirth.”2 — Patrick Chamoiseau

Full textAbstract:
The primary objective of the presented research is to explore and outline the possibilities offered by digital platforms in the urban context of the future, enabling the the well-being and care of individuals and communities, asserting that in a fragmented social context, the development of aggregation services and reconfiguration of social networks is crucial to respond to pluralisation and changing needs (Kazepov & Barberis, 2013; Kazepov & Cefalo, 2009). The research is part of the project, funded under XX, which aims to design 'platforms of care' to improve the holistic well-being of citizens in their territorial and cultural context. The first phase of the research concerns the study of the city from a multidisciplinary point of view, integrating theoretical and practical methods from the technical disciplines of design and architecture with those provided by humanistic and social fields, such as socio-semiotics, cultural studies, and urban sociology. The research investigates the intrinsic correlation between digital transformation and progress in the broad context of citizen care and welfare, with a focus in the welfare sector, aimed at promoting economic, environmental and social sustainability while improving responsiveness to emerging social challenges and needs. Digital services can offer support for new services by encouraging and facilitating proximity interactions for better living in today's hybrid physical and digital space (Pais, 2021). In this regard, the paper presents the outcomes of the initial phase of the research, about the analysis of existing digital platforms for the organisation and provision of holistic care services in the Italian national context, promoted by public administrations (PA) and the third sector. In particular, the case studies considered concern the welfare platforms active in Italian cities, covering sectors such as social welfare, education, care, and physical well-being. Strengths and critical points are critically highlighted, particularly with respect to the relationship with citizens and the territorial and cultural context of reference. The robust interconnection between "care" practices and the structure of the city, typical of pre-modern urban contexts, has been gradually replaced by the evolution of increasingly functional and specialised proximity relations in contemporary cities as a result of digital evolution, pushing towards cities of distance, inherently devoid of care. Proximity, understood in the condition of being physically close in space, but also in the feeling arising from the awareness of sharing something with someone (Manzini, 2021) is here understood as a source of care; an ecosystem of people, organisations, places, products and services that collectively demonstrate a mutual capacity for care and wellbeing. The very concept of care emphasises the importance of contact and thus proximity, recognising how holistic care requires close interaction between the actors involved (Manzini, 2021). The physical-digital hybridisation of proximity is intertwined with the analogous hybridisation of care, making tangible the need to redesign care systems to support new communities and forms of proximity, inclusive and capillary over the territory, considering the city of proximity as a common good. The city of proximity becomes a social and material resource of all its citizens, who contribute to its production, and of which they must have the burden Moreover, today the outcomes of digitisation also involve welfare, requiring the transformation of services such as education, health, welfare and social protection services. The welfare of the future requires physical and non-physical places where people can overcome the barriers of sociability, creating the basis for a new community-type cohesion: the ability to establish proximity relations is closely linked to the long-range relations of community welfare. This gives rise to the phenomenon of welfare platforms, based on the principle of several people providing collaborative responses to needs, actively involving social actors and creating interactions, thus strengthening community resources (Arcidiacono et al., 2021; Fosti, 2013, 2016). The platform, in this context, acts as the main infrastructure linking the demand and supply of goods and services through their reorganisation. The methodological approach of the research considers human-centred design, declined with respect to the emerging phenomenon of digitization. The outcomes of the ongoing research presented consist in mapping the reference city context, the city of XX, its significant places, as well as the characteristics, habits and cultures of its citizens. The sociological analysis will support the technical analysis in the field by means of qualitative survey tools in order to outline realistic scenarios as a basis for the design of 'digital platforms of care and well-being'.

Нарушенность верхних ярусов лесных массивов, обусловленная влиянием пожаров, сплошных лесосечных рубок или насекомых-вредителей, является одним из ключевых факторов, определяющих состояние лесных экосистем. В статье изложены результаты анализа нарушенности хвойных лесов лесостепной зоны Центрального Черноземья, обусловленной воздействием негативных факторов в период 2000-2018 гг. С использованием автоматизированного подхода на основе разновременной многозональной спутниковой съемки Landsat выполнено геоинформационное картографирование участков нарушенных хвойных лесных экосистем, появившихся в соответствующий период. В 2000-2018 гг. доля нарушенных лесов составила 18,4 от общей площади хвойных лесных массивов. Наиболее высоких значений этот показатель достигает на юге лесостепной зоны в Воронежской и Белгородской области. Доля хвойных лесов и смешанных лесов с присутствием хвойных пород в общей площади нарушенных лесных экосистем составляет 76 . Лесные массивы с долей нарушенных участков более 25 в хвойных лесах составляют более четверти от общей площади. Леса, нарушенность верхних ярусов которых составляет не более 10 , занимают 60 всех хвойных лесов. С использованием спутниковых данных Landsat-8 изучена спектральноотражательная способность хвойных лесных экосистем с разной долей нарушенных лесных участков. В спектральных диапазонах 1,56-1,66 мкм, 2,1-2,3 мкм установлена тенденция к последовательному увеличению коэффициентов спектральной яркости вследствие увеличения доли нарушенных участков в лесных массивах. Воздействие болезней деревьев и лесные пожары в исследуемый период являлись основными причинами высокой нарушенности древостоя хвойных лесов. The overstorey of forest cover may be disturbed by fires, clear felling or pests being the key factors determining the condition of forest ecosystems. This paper presents the results of disturbance analysis in coniferous forests of the forest-steppe zone of the Central Chernozemye Region of Russia over the period from 2000 to 2018. Geo-information mapping of disturbed coniferous areas was carried out using Landsat multi-temporal multispectral satellite images. In 2000-2018 the share of disturbed forests was 18.4 of the total area of coniferous forests. This indicator is the highest in the south of the forest-steppe zone - in the Voronezh and Belgorod regions. The share of coniferous forests in the total area of disturbed forest ecosystems is 76 . Forests with a share of disturbed areas exceeding 25 make up more than a quarter of the total area of coniferous forests. Forests with up to 10 disturbed overstorey occupy 60 of all coniferous forests. The spectral reflectivity of disturbed coniferous forest was studied using Landsat-8 data. In the spectral bandwidth between 1.56-1.66 m and 2.1-2.3 m there is a trend toward a gradual increase in reflectance as a result of the growing areas of disturbed forest. The main causes of disturbance revealed in coniferous forest are the impact of wood diseases and forest fires.

Разрабатываемая методология геоэкологического мониторинга основана на выявлении антропогенных источников вещества и наблюдении связей между ними и объектами среды путем рассмотрения объектов в качестве смесей, а источников в качестве их компонентов, с использованием подходов ландшафтного мониторинга. Обоснованы методические подходы к разработке картографического обеспечения мониторинга структуры загрязнения и распределения загрязнителей в бассейне озера Байкал. Для обоснования сети наблюдений и контроля, экстраполяции результатов мониторинга на территории, не охваченные непосредственными наблюдениями, показа оперативной информации о состоянии геосистем и экосистем требуется картографическая основа. Методика картографирования базируется на основных положениях учения о геосистемах В.Б. Сочавы. Методические приемы геоинформационного картографирования были адаптированы применительно к бассейну оз. Байкал. Модель SRTM 4й версии, взятая за основу для получения изолиний рельефа, была преобразована и приведена к масштабу 1:5 000000, а все цифровые слои были интегрированы в единую картографическую проекцию и систему координат (WGS 84). Сопоставление пространственно привязанных слоев рельефа и гидрографической сети в QGIS позволило разграничить бассейны крупных, средних и малых притоков Байкала. Инструментами выявления структуры хозяйственной деятельности служат методы ландшафтногеохимического синтеза, картографирования агроландшафтов, ландшафтного планирования и ретроспективного картографического анализа геосистем с длительной историей хозяйственного освоения. Выявление структуры загрязнения Байкала, его притоков и водосборного бассейна в целом осуществляется путем анализа пространственного и временного распределения загрязнителей в компонентах природной среды. Картографирование дифференциации загрязнителей проводится с использованием современных методов геоинформационного анализа и моделирования, которые реализованы в программе ArcGIS 10. Расчет составов выбросов неизвестных источников проводится с применением методов многомерного анализа. Проанализированы основные параметры ландшафтногеохимической дифференциации бассейна озера Байкал, составлена карта дифференциации поверхностных вод по способности вод к самоочищению, разработана схема районирования территории по способности обеспечивать тот или иной состав вод. The developed methodology of geoenvironmental monitoring is based on identification of anthropogenic sources of substance and the observation of communications between them and the objects of the environment by consideration of the objects as mixes, and the sources as their components, with use of approaches of landscape monitoring. Methodical approaches to development of cartographic ensuring of monitoring of pollution and distribution of pollutants in the basin of Lake Baikal are proved. The cartographic basis is necessary for justification of the network of observations and monitoring, extrapolation of results of monitoring on the territories which are not captured by immediate observations, display of operational information on a condition of geosystems and ecosystems. The technique of mapping is based on original positions of V.B. Sochava doctrine about geosystems. Methodical techniques of geoinformation mapping were adapted in relation to the basin of Lake Baikal. The SRTM model of the 4th version taken as a basis for receiving isolines of a relief was transformed and scaled by 1:5,000,000. All digital layers were integrated into a uniform cartographic projection and a frame (WGS 84). Comparison of spatially attached layers of a relief and a hydrographic network in QGIS allowed us to differentiate the pools of the large, average and small inflows of Baikal. The methods of landscapegeochemical synthesis, mapping of agrolandscapes, landscape planning and the retrospective cartographic analysis of geosystems with the long history of economic development served as the instruments of identification of the structure of economic activity. Identification of pollution structure of Lake Baikal, its inflows and a catchment basin in general is carried out by the analysis of spatial and temporary distribution of pollutants in environment components. Mapping of pollutants differentiation is carried out with use of the modern methods of the geoinformational analysis and the model operation, which are realized in the ArcGIS 10 program. Calculation of compositions for the emissions of unknown sources is carried out with application of methods of the multidimensional analysis. Key parameters of landscapegeochemical differentiation of the basin of Lake Baikal are analyzed. The map of differentiation of the surface water on ability of waters to selfcleaning has been compiled. The scheme of regionalization for the territory on ability to provide this or that composition of waters has been developed.

Full textAbstract:
Monitoring and modeling of coastal vegetation and ecosystems are major challenges, especially when considering environmental response to hazards, disturbances, and management activities. Remote sensing applications can provide alternatives and complementary approaches to the often costly and laborious field-based collection methods traditionally used for coastal ecosystem monitoring. New and improved sensors and data analysis techniques have become available, making remote sensing applications attractive for evaluation and potential use in monitoring coastal vegetation properties and ecosystem conditions and changes. This study involves the extraction of vegetation metrics from airborne lidar and hyperspectral imagery (HSI) collected by the US Army Corps of Engineers (USACE) National Coastal Mapping Program (NCMP) to quantify coastal dune vegetation characteristics. A custom geoprocessing toolbox and associated suite of tools were developed to allow inputs of common NCMP lidar and imagery products to help automate the workflow for extracting prioritized dune vegetation metrics in an efficient and repeatable way. This study advances existing coastal ecosystem knowledge and remote sensing techniques by developing new methodologies to classify, quantify, and estimate critical coastal vegetation metrics which will ultimately improve future estimates and predictions of nearshore dynamics and impacts from disturbance events.

We present two case studies in which coastal vulnerability modeling was used to quantify the role those coastal ecosystems play in reducing risk to coastal communities now and with future sea-level rise. These analyses were used to inform post-disaster reconstruction and coastal resilience building efforts as well as climate change adaptation strategies. Our goal is to quantify the role that coastal habitat plays in reducing risk to people and shoreline under current conditions and with future sea level rise (SLR). With SLR, we find that the extent of shoreline most exposed to coastal hazards would more than double, and the total population would nearly triple in The Bahamas. Similarly, the population living along high-risk shorelines increases by over 10x if habitat is lost and sea level rise is accounted for in the Mesoamerican Reef.

The uncertainty around the impacts of changing climate poses a significant challenge to sustaining forest ecosystems in the Northeast. Important work has been done downscaling projected changes in climate conditions, modeling shifts in suitable habitat, and mapping disturbance patterns across the region, but no one effort has combined all these predictive tools into one cohesive dataset. The goal of this project is to aggregate these valuable but disparate spatial data sets to quantify a more comprehensive assessment of relative exposure to climate change impacts at the species, and community level.

Full textAbstract:
This study was conducted to inventory, classify, and map soils and vegetation within the ecosystems of Katmai National Park and Preserve (KATM) using an ecological land survey (ELS) approach. The ecosystem classes identified in the ELS effort were mapped across the park, using an archive of Geo-graphic Information System (GIS) and Remote Sensing (RS) datasets pertaining to land cover, topography, surficial geology, and glacial history. The description and mapping of the landform-vegetation-soil relationships identified in the ELS work provides tools to support the design and implementation of future field- and RS-based studies, facilitates further analysis and contextualization of existing data, and will help inform natural resource management decisions. We collected information on the geomorphic, topographic, hydrologic, pedologic, and vegetation characteristics of ecosystems using a dataset of 724 field plots, of which 407 were sampled by ABR, Inc.—Environmental Research and Services (ABR) staff in 2016–2017, and 317 were from existing, ancillary datasets. ABR field plots were located along transects that were selected using a gradient-direct sampling scheme (Austin and Heligers 1989) to collect data for the range of ecological conditions present within KATM, and to provide the data needed to interpret ecosystem and soils development. The field plot dataset encompassed all of the major environmental gradients and landscape histories present in KATM. Individual state-factors (e.g., soil pH, slope aspect) and other ecosystem components (e.g., geomorphic unit, vegetation species composition and structure) were measured or categorized using standard classification systems developed for Alaska. We described and analyzed the hierarchical relationships among the ecosystem components to classify 92 Plot Ecotypes (local-scale ecosystems) that best partitioned the variation in soils, vegetation, and disturbance properties observed at the field plots. From the 92 Plot Ecotypes, we developed classifications of Map Ecotypes and Disturbance Landscapes that could be mapped across the park. Additionally, using an existing surficial geology map for KATM, we developed a map of Generalized Soil Texture by aggregating similar surficial geology classes into a reduced set of classes representing the predominant soil textures in each. We then intersected the Ecotype map with the General-ized Soil Texture Map in a GIS and aggregated combinations of Map Ecotypes with similar soils to derive and map Soil Landscapes and Soil Great Groups. The classification of Great Groups captures information on the soil as a whole, as opposed to the subgroup classification which focuses on the properties of specific horizons (Soil Survey Staff 1999). Of the 724 plots included in the Ecotype analysis, sufficient soils data for classifying soil subgroups was available for 467 plots. Soils from 8 orders of soil taxonomy were encountered during the field sampling: Alfisols (<1% of the mapped area), Andisols (3%), Entisols (45%), Gelisols (<1%), Histosols (12%), Inceptisols (22%), Mollisols (<1%), and Spodosols (16%). Within these 8 Soil Orders, field plots corresponded to a total of 74 Soil Subgroups, the most common of which were Typic Cryaquents, Typic Cryorthents, Histic Cryaquepts, Vitrandic Cryorthents, and Typic Cryofluvents.

Full textAbstract:
Riparian vegetation, defined as multilayered herbaceous and woody plant communities along river margins or bank edges, and freshwater submerged aquatic vegetation (SAV), described as rooted aquatic plants in shallow rivers, lakes, and estuaries, are key factors influencing the connection between river and floodplain systems. These vegetation types are often used as indicators of riparian health. Current data on riparian vegetation and SAV are essential for addressing future water resource needs, particularly for restoration monitoring and flood risk management. The US Army Corps of Engineers (USACE), as the federal government’s largest water resources development and management agency, requires updated monitoring and assessment methods to support the development, utilization, and conservation of water and related resources. Assessing large riparian corridors involves characterizing baseline conditions, habitat extents, vegetation patterns, and health. Vegetation and habitat data are critical for evaluating the effects of project operations, resource management, and restoration outcomes downstream from USACE dams. However, obtaining such data across large, dynamic, and inaccessible river reaches is challenging. Integrating field-based techniques with remote-sensing technology offers opportunities to map larger areas comprehensively and adapt to future water resource needs. This report reviews re-mote sensing methods for mapping riparian and SAV habitats with emphasis on vegetation characteristics.

Full textAbstract:
Integrated landscape management for sustainable livelihoods and positive environmental outcomes has been desired by many developing countries, especially for mountainous areas where agricultural activities, if not well managed, will likely degrade vulnerable landscapes. This research was an attempt to characterize the landscape in Chieng Yen Commune, Son La Province in Northwest Viet Nam to generate knowledge and understanding of local conditions and to propose a workable governance mechanism to sustainably manage the landscape. ICRAF, together with national partners — Vietnamese Academy of Forest Sciences, Soil and Fertilizer Research Institute — and local partners — Son La Department of Agriculture and Rural Development, Son La Department of Natural Resources and Environment, Chieng Yen Commune People’s Committee — conducted rapid assessments in the landscape, including land-use mapping, land-use characterization, a household survey and participatory landscape assessment using an ecosystem services framework. We found that the landscape and peoples’ livelihoods are at risk from the continuous degradation of forest and agricultural land, and declining productivity, ecosystem conditions and services. Half of households live below the poverty line with insufficient agricultural production for subsistence. Unsustainable agricultural practices and other livelihood activities are causing more damage to the forest. Meanwhile, existing forest and landscape governance mechanisms are generally not inclusive of local community engagement. Initial recommendations are provided, including further assessment to address current knowledge gaps.

Full textAbstract:
This report addresses two objectives: (1) an island-wide survey and mapping initiative to document habitat and landcover types present on Deer Island, Mississippi, and (2) an evaluation of forested resources on Deer Island along with recommendations to improve and expand the extent of maritime forests on the island. Diverse habitats were documented, including more than 30 distinct habitat and landcover types ranging from wetland marshes to maritime forests and sand ridges. The habitat and landcover survey (and accompanying maps) support ongoing and future ecosystem restoration activities, provides baseline data to conduct change analysis over time, and informs decision-making related to the management of the island’s natural resources. Additionally, the characterization of Deer Island’s forests documented a range of forest health conditions dictated by elevation gradients, soils, invasive species presence, and other factors. Collectively, the data presented inform ongoing planning efforts related to restoration activities on the island as well as future management opportunities to ensure Deer Island continues to provide ecological functions that benefit the community of Biloxi, Mississippi. The results and recommendations herein are broadly applicable to other barrier islands across the northern Gulf region and promotes additional research into the ecology of these unique coastal features.

Full textAbstract:
Permafrost conditions in the Slave Geological province are not well understood. Thaw of permafrost and associated ground ice can reduce ground stability, which modifies terrain and drainage patterns and affects terrestrial and aquatic ecosystems. This presents critical challenges to northern resource development and societies where thaw of ice-rich permafrost negatively affects the integrity of ground-based infrastructure. In an effort to address this knowledge gap, this report presents a digital georeferenced database of landforms identified in permafrost terrain using high-resolution satellite imagery and provides information on geomorphic indicators of ground ice presence and thaw susceptibility. Digital georeferenced databases compiled from sedimentological and cryostratigraphic records are also provided. The landform database is focused on mapping within a 10 km-wide swath of land (8576 km2 area of interest) centred on the proposed corridors for the 773 km-long Slave Geological Province Corridor Project, NT, and the Grays Bay Road and Port Project, NU. The geomorphic features were classified and digitized using high-resolution (0.5 m) satellite imagery following an existing protocol, which was modified by using a very high-resolution (2 m) digital elevation model (DEM), and by including mapping criteria for additional features. A total of 1393 geomorphic features were mapped comprising 10 different types, which were categorized into 3 classes that include periglacial (1291), hydrological (88), and mass movement (14) features. Data from 254 geotechnical boreholes and 2243 granular deposits were compiled. Information from the compiled databases was analyzed with surficial geology information. Results indicate that the distributions and densities of mapped landforms varied substantially according to surficial geology. High ground ice contents may be quite common in glaciofluvial deposits where creep of frozen ground affects about 30% of eskers. And ground ice may be more extensive overall than the available geotechnical data indicate. Borehole and granular deposit data suggest that overburden thickness above bedrock was up to 25.5 m, and visible ground ice contents were generally between 10% and 30%, but were up to 60% in glacial blanket and glaciofluvial sediments.
