Interactions between changes in land cover and potential of ecosystem services in Lithuania at temporal and spatial scale

The growing interest in ecosystem services is mainly related to land use changes. The aim of the study is to analyse spatial-temporal changes in the capacity to supply of ES in Lithuania based on land use changes in 1990–2018. The results show some balance between loss and gains of ecosystem services capacity due to land use changes. Decrease in heterogenous agricultural areas had negative impact on provision of ecosystem integrity and services. Considerable increase in scrubland and herbaceous vegetation areas significantly increased the ecosystem service potential. The conversion of former agricultural land to less intensively managed ecosystems enhance the potential of valuable habitats for biodiversity and ecosystem services associated with natural grasslands, moors and heathland, transitional woodland shrubs. The urbanization process along with increase in urban fabric areas had little effect on ESs potential since artificial vegetated areas had compensated the loss of ESs due to increased areas of urbanized ecosystems. Despite the area of open spaces slightly increased, this led to decrease of provision of ESs. Temporal changes in overall ESs capacity indicated an increase in Lithuania over the last two decades. Given the observed dynamic context of land cover, the structure of ecosystem services may face potential threats from land use change due to urban development and agricultural activities.

Remotely Sensed Tree Characterization in Urban Areas: A Review

Urban trees and forests provide multiple ecosystem services (ES), including temperature regulation, carbon sequestration, and biodiversity. Interest in ES has increased amongst policymakers, scientists, and citizens given the extent and growth of urbanized areas globally. However, the methods and techniques used to properly assess biodiversity and ES provided by vegetation in urban environments, at large scales, are insufficient. Individual tree identification and characterization are some of the most critical issues used to evaluate urban biodiversity and ES, given the complex spatial distribution of vegetation in urban areas and the scarcity or complete lack of systematized urban tree inventories at large scales, e.g., at the regional or national levels. This often limits our knowledge on their contributions toward shaping biodiversity and ES in urban areas worldwide. This paper provides an analysis of the state-of-the-art studies and was carried out based on a systematic review of 48 scientific papers published during the last five years (2016–2020), related to urban tree and greenery characterization, remote sensing techniques for tree identification, processing methods, and data analysis to classify and segment trees. In particular, we focused on urban tree and forest characterization using remotely sensed data and identified frontiers in scientific knowledge that may be expanded with new developments in the near future. We found advantages and limitations associated with both data sources and processing methods, from which we drew recommendations for further development of tree inventory and characterization in urban forestry science. Finally, a critical discussion on the current state of the methods, as well as on the challenges and directions for future research, is presented.

Connecting ecosystem services science and policy in the field

Conservation and provision of ecosystem services (ES) have been adopted as high‐level policy in many countries, yet there has been surprisingly little application of these broad policies in the field; for example, ES are rarely considered in permit issuance or other discrete agency actions. This large implementation gap arises in part because the science that drove general policy interest in ES differs from the science needed for practical application. A better understanding of the environmental policy toolkit can guide more effective research to support agency decisions. Here, we outline the framework used to teach environmental policy instruments through the “Five P’s”: prescription, property, penalty, payment, and persuasion. We then discuss the discrete ES research required to effectively implement each tool. To support greater conservation of ES in the field, scientists and policy makers must clearly recognize what each needs from the other.

The value of cultural ecosystem services in a rural landscape context

Academic interest in ecosystem services has been growing in the past ten years or more with an increasing number of research studies and papers being dedicated to this complex and diverse field of enquiry. However, Cultural Ecosystem Services have been relatively under-researched, especially in terms of their value to landscapes. The Millennium Ecosystem Assessment (2005) argued that cultural services and values were not recognised enough in landscape planning and management, therefore the implications for rural landscape development are considered in this paper. This paper focuses on the value of Cultural Ecosystem Services in two rural landscapes in Hungary (Őrség and Kalocsa) using in-depth interviews with a range of local stakeholders. The research analyses the relative value of different categories of Cultural Ecosystem Services focusing mainly on social, symbolic and economic values. The findings reveal the central importance of cultural heritage in relation to other categories of CES, especially its social and symbolic values.

Analysis of Particulate Matter Concentration Intercepted by Trees of a Latin-American Megacity

Urban areas with trees provide several ecosystem services to citizens. There is a growing interest in ecosystem services for the removal of air pollutants such as particulate matter. The objective of this paper is to show a study on the variation of intercepted particulate matter concentration (IPMC) by tree leaves in the megacity of Bogotá (Colombia). The relationship between IPMC and PM2.5 concentrations observed in air quality stations in two urban zones with different air pollutions was studied. Influences of climate and leaf morphology variables on IPMC were also analyzed. The species under study were Ligustrum-lucidum, Eucalyptus-ficifolia, Tecoma-stans, Callistemon-citrinus, Lafoensia-acuminata, and Quercus-humboldtii. The results showed that leaf IPMC decreased as the PM2.5 concentration increased. Species that best described this trend were Ligustrum-lucidum and Lafoensia-acuminata. These two species also showed the largest IPMC in their leaves. Indeed, species that showed the largest leaf area were those with the highest IPMC. On average, it was observed that for each 5.0 µg/m3 increase in PM2.5 concentration the IPMCs of the species Ligustrum-lucidum and Lafoensia-acuminata decreased by 33.6% and 23.1%, respectively. When wind speed increased, there was also an increase in PM2.5 concentrations and a reduction in the leaf IPMCs.

Ecosystem Services as a Promising Paradigm to Protect Environmental Rights of Indigenous Peoples in Latin America: the Constitutional Court Landmark Decision to Protect Arroyo Bruno in Colombia.

In the last years, the interest in ecosystem services (ESs) as a decision-making tool for environmental policy has been growing. The ES paradigm has also impacted the judicial system and in some countries the common law tradition. Experiences and lessons learned from the ES litigation have been already documented. In the initial analysis, this article aims to identify key trends in ESs case law in Latin America—a leading region in environmental constitutionalism—by exploring the judicial decisions issued by high courts and subnational environmental courts that mention or incorporate the ES term. In the second level of analysis, we focused on the Colombian Constitutional Court landmark decision; the Arroyo Bruno judgment aimed to protect the rights to water, food security, and health of the Wayuú indigenous people. We argue this is a groundbreaking ruling in Latin America, given that for the first time, a Court uses the ES-based approach to protect the environmental rights of ethnic communities, incorporating ES concepts to the constitutional law sphere and integrating into the same conversation, interdisciplinary and intercultural knowledge.

Forest land use discontinuity and northern red oak Quercus rubra introduction change biomass allocation and life strategy of lingonberry Vaccinium vitis-idaea

BackgroundMulti-purpose use of forests in a sustainable way forces a recognition of how introduction of alien woody species in forests with different land use histories affect native plants other than trees. Lingonberry Vaccinium vitis-idaea is an important understory component of temperate and boreal forests and provider of valuable non-wood forest products. Here we studied effects of land use changes and introduction of Northern red oak Quercus rubra on lingonberry in mesic Scots pine forests (in central Poland). We measured lingonberry cover, height of shoots, biomass of stems and leaves, and fruit productivity. Shoots were collected within 200 research plots located in recent and ancient Scots pine forests, with and without Q. rubra.ResultsWe found that V. vitis-idaea reached lower cover, aboveground biomass and fruit production in recent than ancient forests and in forests with than without Q. rubra. The fruit production in recent pine forest was only 2% of that reported in ancient pine forest, and V. vitis-idaea did not reproduce generatively in forests with Q. rubra. Biomass and carbon sequestration of V. vitis-idaea in forests with alien (invasive) trees decreased by 75% compared to ancient pine forest. Effects were also clear at the individual shoot level – in less suitable conditions we found taller heights and higher biomass allocation into stems than foliage. Biomass allocation in fruiting and non-fruiting shoots in pine forests was also different – less of the dry biomass of fruiting shoots was allocated to leaves than to stems.ConclusionsIn the age of high interest in ecosystem services and discussions about usage of alien tree species as alternatives in forest management, our results clearly indicate disruption of ecosystem services provided by V. vitis-idaea in the presence of Q. rubra. Lingonberry benefited from the continuity of forest land use, however, regardless of land-use legacy, alien tree introduction led to decline in abundance of species crucial for ecosystem functioning. Therefore, to maintain valuable native species and for conservation of ecosystem services delivery, we suggest limiting the introduction of Q. rubra in areas with abundant V. vitis-idaea, especially in forests with continuous forest land-use history.

Integrating ecosystem services in power analysis in forest governance: A comparison across nine European countries

Within forest governance research, the transfer of power from governmental actors to civil society and market actors has been subject to intense scientific debate. We move forward on this debate by analyzing how ongoing transformations and power shifts in forest governance affect the power relations of actors with interest in various ecosystem services (ESs) in nine countries (Germany, Ireland, Italy, Lithuania, Portugal, Slovakia, Sweden, the Netherlands, Turkey). In order to examine power resources of actors, we triangulated 220 qualitative interviews, document analysis, and participatory observations. Governmental actors (with various interests in ESs) were the most powerful actors in most countries, and thus drove forest management. Our analysis shows that the power relations of actors with interest in different forest ESs, varied within the nine countries, though many similarities existed. Governmental, market, and civil society actors differed in their capacity to apply the power strategies “coercion”, “(dis)incentives”, and “dominant information”, to realize their interests in ESs. In Lithuania, Slovakia and Turkey, governmental actors relied mostly on coercion; in the Netherlands on incentives; and in Sweden on dominant information. In Germany, Ireland, Italy and Portugal governmental actors relied on a mix of coercion, incentives, and dominant information. Market actors in all countries relied mostly on incentives, and civil society actors on dominant information as their power strategy.

Capacity as “virtual stock” in ecosystem services accounting

Interest in ecosystem services accounting is growing exponentially. There are many un-solved issues that need to be addressed, the notion of capacity is among them. International guidelines suggest that capacity should constitute the link between the ecosystem assets accounts and the ecosystem services accounts. In order to address this issue, the authors use Supply and Use table for ecosystem services to show the relationship between (i) ecosystem assets and (ii) capacity, intended as “virtual stock” of individual ecosystem services. It is in fact important to distinguish ecosystem assets from capacity as “virtual stock”: a comparison between asset accounts for natural resources and capacity is presented to clarify this difference. This novel approach is described together with its implications in order to feed further developments and discussion.

Interest in the biosphere and students environmental awareness and optimism: A global perspective

This study focuses on students' interest in ecosystem services and sustainability to explain their awareness and optimism about the environmental issues of air pollution, water shortage and greenhouse gas emission in 50 countries around the world. We achieve this using the cross-sectional survey data of the 2015 OECD's Program for International Student Assessment (PISA), along with seemingly unrelated bi-variate weighted ordered probit modeling. We found that in addition to factors such as age, gender, immigration status, and economic, social and cultural status, interest in the biosphere is a significant determinant of students' environmental awareness and optimism. In fact, a level increase in students' interest in ecosystem services and sustainability is found to raise on average their awareness level by 15.3% for the issue of air pollution, 15.7% for the issue of water shortage, and 24.6% for the issue of greenhouse gas emission. Although students' interest in the biosphere seems to not have a significant effect on their expectations about the issue of greenhouse gas emission, it does however raise their level of optimism by 0.8% for the issue of air pollution, and 0.2% for the issue of water shortage. Furthermore, every level increase in students' environmental awareness is found to raise their optimism level by 17.3% for the issue of air pollution, 15.8% for the issue of water shortage, and 17.4% for the issue of greenhouse gas emission. Therefore, relying on the Theory of Planned Behavior (TPB), our results suggest that governments and policy makers around the world could successfully leverage the biospheric interests of their youth populations to successfully achieve their 2030 goals for sustainability.

Cultural Heritage and Ecosystem Services: A Literature Review

During the last decade, we have witnessed an increased interest in Ecosystem Services (ES), including the so-called ‘cultural ecosystem services’ and its subcategory of ‘cultural heritage’. In this article, a review of academic literature of ES and cultural heritage is carried out. ES has primarily been developed by scholars from the ecological and economic disciplines, and in this article, we discuss how this impacts the way in which cultural heritage is used and conceptualised in ES literature. Based on the conceptual review, we initiate a discussion of what the implications for cultural heritage management could be if the heritage sector adopts the rationales in the ES framework.

Drones as a Tool for Monoculture Plantation Assessment in the Steepland Tropics

Smallholder tree plantations are expanding in the steepland tropics due to demand for timber and interest in ecosystem services, such as carbon storage. Financial mechanisms are developing to compensate vegetation carbon stores. However, measuring biomass—necessary for accessing carbon funds—at small scales is costly and time-intensive. Therefore, we test whether low-cost drones can accurately estimate height and biomass in monoculture plantations in the tropics. We used Ecosynth, a drone-based structure from motion technique, to build 3D vegetation models from drone photographs. These data were filtered to create a digital terrain model (DTM) and digital surface model (DSM). Two different canopy height models (CHMs) from the Ecosynth DSM were obtained by subtracting terrain elevations from the Ecosynth DTM and a LIDAR DTM. We compared height and biomass derived from these CHMs to field data. Both CHMs accurately predicted the height of all species combined; however, the CHM from the LiDAR DTM predicted heights and biomass on a per-species basis more accurately. Height and biomass estimates were strong for evergreen single-stemmed trees, and unreliable for small leaf-off species during the dry season. This study demonstrates that drones can estimate plantation biomass for select species when used with an accurate DTM.

Informative plot sizes in presence‐absence sampling of forest floor vegetation

Summary Plant communities are attracting increased interest in connection with forest and landscape inventories due to society's interest in ecosystem services. However, the acquisition of accurate information about plant communities poses several methodological challenges. Here, we investigate the use of presence‐absence sampling with the aim to monitor state and change in plant density. We study what plot sizes are informative, i.e. the estimators should have as high precision as possible. Plant occurrences were modelled through different Poisson processes and tests were developed for assessing the plausibility of the model assumptions. Optimum plot sizes were determined by minimizing the variance of the estimators. While state estimators of similar kind as ours have been proposed in previous studies, our tests and change estimation procedures are new. We found that the most informative plot size for state estimation is 1·6 divided by the plant density, i.e. if the true density is 1 plant per square metre the optimum plot size is 1·6 square metres. This is in accordance with previous findings. More importantly, the most informative plot size for change estimation was smaller and depended on the change patterns. We provide theoretical results as well as some empirical results based on data from the Swedish National Forest Inventory. Use of too small or too large plots resulted in poor precision of the density (and density change) estimators. As a consequence, a range of different plot sizes would be required for jointly monitoring both common and rare plants using presence‐absence sampling in monitoring programmes.

Ecosystem services in the Great Lakes.

A comprehensive inventory of ecosystem services across the entire Great Lakes basin is currently lacking and is needed to make informed management decisions. A greater appreciation and understanding of ecosystem services, including both use and non-use services, may have avoided misguided resource management decisions in the past that have resulted in legacies inherited by future generations. Given the interest in ecosystem services and lack of a coherent approach to addressing this topic in the Great Lakes, a summit was convened involving 28 experts working on various aspects of ecosystem services in the Great Lakes. The invited attendees spanned a variety of social and natural sciences. Given the unique status of the Great Lakes as the world's largest collective repository of surface freshwater, and the numerous stressors threatening this valuable resource, timing was propitious to examine ecosystem services. Several themes and recommendations emerged from the summit. There was general consensus that 1) a comprehensive inventory of ecosystem services throughout the Great Lakes is a desirable goal but would require considerable resources; 2) more spatially and temporally intensive data are needed to overcome our data gaps, but the arrangement of data networks and observatories must be well-coordinated; 3) trade-offs must be considered as part of ecosystem services analyses; and 4) formation of a Great Lakes Institute for Ecosystem Services, to provide a hub for research, meetings, and training is desirable. Several challenges also emerged during the summit, which are discussed in the paper.

Soil “Ecosystem” Services and Natural Capital: Critical Appraisal of Research on Uncertain Ground

Over the last few years, considerable attention has been devoted in the scientific literature and in the media to the concept of services of soils. The monetary valuation of these services, demanded by many governments and international agencies, is often depicted as a necessary condition for the preservation of the natural capital that soils represent. This focus on soil services is framed in the context of a general interest in ecosystem services that allegedly started in 1997, and took off in earnest after 2005. The careful analysis of the literature proposed in this article shows that, in fact, interest in the multifunctionality of soils emerged already in the mid-60s, at a time when hundreds of researchers worldwide were trying, and largely failing, to figure out how to put price tags meaningfully on nature's services. Soil scientists, since, have tried to better understand various functions/services of soils, as well as their possible relation with key soil characteristics, like biodiversity. They have also tried to make progress on the challenging quantification of soil functions/services. However, researchers have shown very little interest in monetary valuation, undoubtedly in part because it is not clear what economic and financial markets might do with prices of soil functions/services, even if we could somehow come up with such numbers, and because there is no assurance at all, based on neoclassical economic theory, that markets would manage soil resources optimally. Instead of monetary valuation, focus in the literature has been put on decision-making methods, like Multi-Criteria Decision Analysis (MCDA) and Bayesian Belief Networks (BBN), which do not require the systematic monetization of soil functions/services and easily accommodate deliberative approaches involving a variety of stakeholders. A prerequisite to progress in such public deliberations is that participants be very cognizant of the extreme relevance of soils to many aspects of their daily life. We argue that, as long as this prerequisite is satisfied, the combination of deliberative decision-making methods and of a sound scientific approach to the quantification of soil functions/services is a very promising avenue to manage effectively and ethically the priceless heritage that soils constitute.

A global analysis of the seaward salt marsh extent: The importance of tidal range

AbstractDespite the growing interest in ecosystem services provided by intertidal wetlands, we lack sufficient understanding of the processes that determine the seaward extent of salt marsh vegetation on tidal flats. With the present study, we aim to establish a globally valid demarcation between tidal flats and salt marsh vegetation in relation to tidal range. By comparing results from a regional GIS study with a global literature search on the salt marsh‐tidal flat border, we are able to define the global critical elevation, above which salt marsh plants can grow in the intertidal zone. Moreover, we calculate inundation characteristics from global tide gauge records to determine inundation duration and frequency at this predicted salt marsh‐tidal flat border depending on tidal range. Our study shows that the height difference between the lowest elevation of salt marsh pioneer vegetation and mean high water increases logarithmically with tidal range when including macrotidal salt marshes. Hence, the potentially vegetated section of the tidal frame below mean high water does not proportionally increase with tidal range. The data analysis suggests that inundation frequency rather than duration defines the global lower elevational limit of vascular salt marsh plants on tidal flats. This is critical information to better estimate sea level rise and coastal change effects on lateral marsh development.

Ecosystem services and resource management: Institutional issues, challenges, and opportunities in the public sector

Application of ecosystem services measurement and analysis to natural resource planning, investment, and management decisions has gained momentum over the past decade. This momentum springs from a confluence of practical conservation challenges and conceptual developments. In particular, the ecosystem services focus emphasizes an appreciation of the social and economic values of natural resources and ecological systems. Despite a growing interest in ecosystem services and their incorporation into public-sector decisions and transactions, a number of institutional challenges complicate these efforts. These challenges include dispersed agency authorities and jurisdictional fragmentation that may constrain the geographic scale of public-sector transactions or cross-jurisdictional planning and actions. Challenges also include limitations on agency capacities to adjust decisions in the face of changing resource conditions and new information. Nonetheless, many agencies have flexibility to incorporate ecosystem services assessments into their planning, use them to inform spending choices, and develop markets based on ecosystem services concepts. Challenges are, thus, more instrumental and practical rather than legal and structural.

Beyond food production: Ecosystem services provided by home gardens. A case study in Vall Fosca, Catalan Pyrenees, Northeastern Spain

Interest in ecosystem services provided by agroecosystems has grown over the last decades with research focusing on the type of environmental, economic and social benefits delivered by agroecosystems. Researchers suggest that, besides the provisioning of food, fuel, and fiber, agroecosystems provide habitat, cultural, and regulating services. One type of agroecosystem that remains relatively unexplored from an ecosystem service perspective is home gardens. In this paper, we aim at advancing the understanding of the value of home gardens by conducting an assessment of home gardens ecosystem services. For the empirical analysis we use home gardens in Vall Fosca (Catalan Pyrenees). We identify and characterize the most important ecosystem services provided by home gardens, and conduct a valuation of the social importance of home garden ecosystem services. The methodological approach for this work included an in-depth literature review, participant observation, semi-structured interviews, a valuation questionnaire, and a scientific panel consultation. We identified and characterized 19 ecosystem functions and related services. According to our informants, home gardens provide a large set of ecosystem services, being cultural services the category most valued. We found that the most important ecosystem services provided by home gardens differ from those provided by other types of agroecosystems.

A comparison of tools for modeling freshwater ecosystem services

Interest in ecosystem services has grown tremendously among a wide range of sectors, including government agencies, NGO's and the business community. Ecosystem services entailing freshwater (e.g. flood control, the provision of hydropower, and water supply), as well as carbon storage and sequestration, have received the greatest attention in both scientific and on-the-ground applications. Given the newness of the field and the variety of tools for predicting water-based services, it is difficult to know which tools to use for different questions. There are two types of freshwater-related tools--traditional hydrologic tools and newer ecosystem services tools. Here we review two of the most prominent tools of each type and their possible applications. In particular, we compare the data requirements, ease of use, questions addressed, and interpretability of results among the models. We discuss the strengths, challenges and most appropriate applications of the different models. Traditional hydrological tools provide more detail whereas ecosystem services tools tend to be more accessible to non-experts and can provide a good general picture of these ecosystem services. We also suggest gaps in the modeling toolbox that would provide the greatest advances by improving existing tools.

REVIEW: The identification of priority policy options for UK nature conservation

Summary 1. The conservation of biodiversity depends upon both policy and regulatory frameworks. Here, we identify priority policy developments that would support conservation in the UK in the light of technological developments, changes in knowledge or environmental change. 2. A team of seven representatives from governmental organizations, 17 from non‐governmental organizations and six academics provided an assessment of the priority issues. The representatives consulted widely and identified a long‐list of 117 issues. 3. Following voting and discussion during a 2‐day meeting, these were reduced to a final list of 25 issues and their potential policy options and research needs were identified. Many of the policies related to recent changes in approaches to conservation, such as increased interest in ecosystem services, adaptation to climate change and landscape ecology. 4. We anticipate that this paper will be useful for policy makers, nature conservation delivery agencies, the research community and conservation policy advocates. 5. Although many of the options have global significance, we suggest that other countries consider an equivalent exercise. We recommend that such an exercise be carried out in the UK at regular intervals, say every 5 years, to explore how biodiversity conservation can best be supported by linked policy development and research in a changing world. 6. Synthesis and applications. Opportunities for policy development were prioritized and for each of the top 25 we identified the current context, policy options and research questions. These largely addressed new issues relating to developing topics such as ecosystem services, landscape planning and nanotechnology. We envisage that this will largely be used by researchers wishing to make a contribution to potential policy debates.
