Deterioration Of Ecosystem Services Research Articles

Mega project impact on urban growth and ecosystem service

In an effort to forecast and estimate the value of ecosystem services (ESVs) and land use and land cover changes (LULC), recent global events and research have centered on the evaluation of LULC. This study evaluates the effectiveness of an integrated approach using multi-layer perceptron-Markov chain analysis (MLP-MCA) and remote sensing data for monitoring land use and land cover (LULC) changes. The study area comprises the three Bangladeshi upazilas that the Padma Bridge connects: Shariatpur, Louhajang, and Janjira. The Ecosystem Services Valuation Database (ESVD) was used to evaluate the impacts of changes in land use and land cover (LULC) on Ecosystem Service Values (ESVs). The LULC of the study area was estimated for the years 2000, 2010, and 2020, and the forecast period for urban development was 2030 and 2040. Additionally, the monetary value of ecosystem services was evaluated across the time. As per the LULC change analysis, there is a projected 4.35% growth in the built-up area from 2000 to 2020. After the bridge is constructed, the built-up area is projected to increase by 7% in 2030 and 14% in 2040, according to the forecast. The exponential expansion of developed land has a paradoxical effect on the value of ecosystem services. From 2020 to 2040, it is expected that the ESVs for provision, regulation, culture, and support will experience a reduction of approximately 213.24 million USD/ha. Even if the establishment of a bridge results in economic stability and investment attraction for the nation, unforeseen ecosystem service losses cannot contribute to long-term, sustainable development. This study, by establishing a correlation between urban area expansion and the deterioration of ecosystem services, can serve as a standard and basis for guiding management decisions.

Impact of climate change factor on the resource (providing) ecosystem services of the Lower Danube wetlands

Problem Statement. Wetlands perform many vital functions, in particular: accumulation and storage of surface waters; protection from storms and floods; strengthening the coastline and curbing water erosion; hydraulic connection with groundwater; surface water purification; nutrient content; deposit formation; pollutants retention; stabilization of local climatic conditions, especially the amount of precipitation and temperature of the near-surface layer of the atmosphere. They are the world's most productive ecosystems, focus of biodiversity, sources of water and primary productivity on which the existence of innumerable species of plants and animals depends. Wetlands support numerous species of birds, mammals, reptiles, amphibians, fish and invertebrates. The ecological character of wetlands is the totality of their ecosystem components, processes and services at one time or another. Wetland ecosystem services are understood as the benefits that people receive from these. These are providing services (water and food); regulatory services (regulation of floods, droughts, land degradation, etc.); supporting services (soil formation, nutrient cycling, photosynthesis, biodiversity); cultural services (cultural and entertainment, spiritual, religious and other intangible benefits). In Ukraine, there are 2417 wetlands with a total area of about 255 million hectares. Among them are 50 wetlands of international importance with a total area of about 734 thousand hectares, a significant proportion of which falls on the territory of the North-Western Black Sea region coastal zone. The aim of this study is to determine the state, vulnerabilities and climate change impact on the ecosystem services of the «Chilia Branch» wetlands. Research Methodology. To determine the periods of drought, the study used the Standardised Precipitation Evapotranspiration Index (SPEI) from April to October 1980-2023. The SPEI index was calculated at a point located in the southern part of the Danube Biosphere Reserve. The assessment of the state of the vegetation cover was carried out on the basis of the analysis of Normalized Difference Vegetation Index (NDVI) the period 2017-2023 at two sites (Ermakov Island and Limba Island). To analyze dynamics land cover in the wetland area, were used Sentinel-2 land use satellite imagery for the period 2017-2021. Results. Analysis of the SPEI index showed that during the study period there was a positive statistically significant linear trend towards an increase in dry conditions (0.26 / 10 years). In the period 1980-2023 during the growing season on the territory of the "Chilia Branch" wetland, there is a change in weather conditions towards arid, which poses a certain threat. At the same time, it should be noted that the unique hydrological complex of the Danube Delta has a mitigating effect of the atmospheric drought impact on the vegetation. Also, it should be noted that the threat to coastal wetlands is the anthropogenic transformation of coastal natural systems (urbanization processes, expansion of land for agricultural needs, pollution of soil and surface waters), which can lead to loss of habitats of living organisms and deterioration of ecosystem services.

Use and perception of ecosystem services on an urban river: a case from lower Gangatic plain, Eastern India.

Rapid urbanisation and climate change have emerged as serious threats to ecosystem services (ES), and the deterioration of ES is affecting the quality of life. The research on ES was long performed from monetary perspectives and neglected evaluation of ES from social perspectives. This study proposes a social appraisal approach for evaluating urban river ES on Mahananda River in English Bazar Urban Agglomeration (EBUA), Eastern India, through the social perception and preference (SPP) approach. SPP approach was performed using the importance-performance analysis (IPA) model and satisfaction index (SI). Mann-Whitney U test, correlation analysis, and a median regression were performed to better understand the overall scenario on the perception and preference for ES. The findings of the study showed that (i) the stakeholder residing along the left bank of the river were highly dependent on provisioning ES; (ii) there was limited access to cultural ES provided by the river; (iii) the stakeholders residing along the left bank and slum stakeholders residing along the right bank of the river were more dependent on rive ES; (iv) relatively higher discrepancy was reported from recreation, aesthetic, and bio-diversity; (v) satisfaction level on ES was relatively low to the stakeholder residing along the left bank (50%); and (vi) as per improvement index (II), recreation, aesthetic value, bio-diversity, and purification of water must be prioritised to meet the societal needs. Thus, the study's findings can be very effective in implementing actions for sustainable holistic river ES management through the SPP approach.

METHODOLOGICAL BASICS FOR ASSESSING ECONOMIC DAMAGE FROM LOSS OF ECOSYSTEM SERVICES IN CONSEQUENCE OF MILITARY AGGRESSION OF THE RUSSIA

The initial methodological bases for estimating economic damages from the loss of ecosystem services as a result of military aggression are represented for the first time in the domestic specialized literature. An idea was put forward to develop a special "Methodology for assessing the loss of ecosystem services from military actions", which would make it possible to achieve the amount of monetary compensation more adequate to the aggressor's costs of waging war and the actual damage caused to the environment by determining the cost of the loss of ecosystem services and restoration costs the environment. For the first time, the basic formula for the final value assessment of economic damage from the deterioration of ecosystem services as a result of armed aggression is presented and disclosed as an aggregated indicator with the definition of its main total components, in particular: economic damage from the deterioration of ecosystem services; reimbursement of the cost of lost resources and services during the recovery period; lost profits incurred due to the lack of a resource or service during the recovery period; compensations for non-renewable losses of biodiversity, unique ecosystem objects; the cost of carrying out scientific and organizational measures/works on assessing damage from the deterioration of ecosystem services as a result of armed aggression. Attention is focused on the fact that the proposed basic formula for the cost assessment of this damage can be a supporting basis for carrying out its specific assessment at any territorial level and within the selected ecosystems that have been damaged. An idea was put forward regarding the need to take into account the direct and indirect effects of military actions and their consequences that harm the environment, when developing the "Methodology for assessing losses of ecosystem services from military actions". The content of the effects of military actions and their consequences, which harm the natural environment of Ukraine, is revealed. The importance of conducting an assessment of the damage caused by military operations to the environment and ecosystem goods in particular has been established. Such an assessment can be the basis for, firstly, bringing the aggressor to justice; second, to quantify reparations that would more broadly and more accurately reflect the effects of war; thirdly, to receive monetary compensation for the deterioration of ecosystems and their services by the affected socio-territorial communities as their owners.

Compensation mechanism for damage from ecosystem services deterioration: constitutive characteristic

A growing attention of researchers and politicians to the processes of formation and implementation of the environmental compensation mechanism is fixed in the last decade. Environmental compensation has been viewed as a national or regional regulatory mechanism that contributes to balancing the goal of environmental conservation with the goals of sustainable socio-economic development. The literature on the ecosystem service has developed the terminology of the eco-compensation mechanism. Still, they do not define its functional structure within its framework, in particular, a compensation mechanism for damage from the deterioration of ecosystem services. We characterised this crucial but relatively understudied component of the eco-compensation mechanism and suggested a general formula for determining the magnitude of compensatory payments for damages from degradation/destruction of ecosystem services, which will help to improve the implementation of compensatory payments in decision-making as well as drive green economic activity.

Changing environmental conditions underpin long-term patterns of phytoplankton in a freshwater reservoir

Environmental changes can exert strong pressure on freshwater biota and lead to unwanted alterations of local communities and deterioration of ecosystem services. Disentangling the links between environmental and community changes is, therefore, essential to understand and predict the impact of human activities on freshwater ecosystems. This is particularly relevant for man-made freshwater reservoirs that represent a nexus between anthropogenic, environmental, and biotic effects. Reservoir food webs depend strongly on phytoplankton dynamics, which are affected by abiotic conditions, nutrient availability and grazing pressure by zooplankton. We studied the effects of relevant environmental drivers (hydrochemistry, hydrodynamics and zooplankton) on the composition, diversity and community stability of main morpho-functional phytoplankton groups over 32 years in the Římov Reservoir (Czech Republic). Environmental conditions in the reservoir are characterised by three distinct periods (1983–89, 1990–99, and 2000–14) defined by shifts and breakpoints in temporal trends in reservoir hydrochemistry and hydraulic conditions, and we examined if and how phytoplankton responded to these abrupt changes. We found significant differences in phytoplankton composition among the three periods. Phytoplankton underwent a substantial compositional shift towards a dominance of pennate diatoms. Time-lag analysis of dissimilarity in phytoplankton composition revealed higher and stochastic annual variations until 1999, followed by a lower variability and divergence in phytoplankton composition in subsequent years. Changes in overall phytoplankton assemblage and most abundant morpho-functional phytoplankton groups were driven mainly by hydrochemical (total nitrogen) and hydrodynamic variables (inflow rate, surface level and mixing depth) and less by zooplankton dynamics. These results suggest that phytoplankton are driven primarily by nutrient input and water regime, both of which can be appropriately managed to support valuable ecosystem services provided by phytoplankton in freshwater reservoirs.

Land use change has stronger effects on functional diversity than taxonomic diversity in tropical Andean hummingbirds.

Land use change modifies the environment at multiple spatial scales, and is a main driver of species declines and deterioration of ecosystem services. However, most of the research on the effects of land use change has focused on taxonomic diversity, while functional diversity, an important predictor of ecosystem services, is often neglected. We explored how local and landscape scale characteristics influence functional and taxonomic diversity of hummingbirds in the Andes Mountains in southern Ecuador. Data was collected in six landscapes along a land use gradient, from an almost intact landscape to one dominated by cattle pastures. We used point counts to sample hummingbirds from 2011 to 2012 to assessed how local factors (i.e., vegetation structure, flowering plants richness, nectar availability) and landscape factors (i.e., landscape heterogeneity, native vegetation cover) influenced taxonomic and functional diversity. Then, we analyzed environment – trait relationships (RLQ test) to explore how different hummingbird functional traits influenced species responses to these factors. Taxonomic and functional diversity of hummingbirds were positively associated with landscape heterogeneity but only functional diversity was positively related to native vegetation coverage. We found a weak response of taxonomic and functional diversity to land use change at the local scale. Environment‐trait associations showed that body mass of hummingbirds likely influenced species sensitivity to land use change. In conclusion, landscape heterogeneity created by land use change can positively influence hummingbird taxonomic and functional diversity; however, a reduction of native vegetation cover could decrease functional diversity. Given that functional diversity can mediate ecosystem services, the conservation of native vegetation cover could play a key role in the maintenance of hummingbird pollination services in the tropical Andes. Moreover, there are particular functional traits, such as body mass, that increase a species sensitivity to land use change.

Adding ‘iterativity’ to the credibility, relevance, legitimacy: A novel scheme to highlight dynamic aspects of science–policy interfaces

Credibility, relevance and legitimacy (CRELE) of knowledge are widely recognized as key attributes of effective science–policy interfaces (SPIs). Yet, notwithstanding efforts to enhance the CRELE attributes of an SPI, it may still lack impact or be dismissed as not being credible, legitimate or relevant both inside, and outside the SPI. We introduce ‘iterativity’ as an additional attribute to the CRELE framework to better capture dynamic, continuous and multi-directional interactions between science, policy and society related to SPIs. Iterativity is understood in the context of an important shift in perspective by which SPIs are viewed as dynamic, evolving processes rather than linear processes or isolated events. Based on empirical material on biodiversity-related SPIs, we identify 14 features and lessons learned that explain the outcomes of SPIs regarding their participants and external audiences, and examine how SPIs’ structures, objectives, processes and outputs help to build CRELE and iterativity (CRELE + IT). The four attributes of CRELE + IT and results related to the features explaining outcomes of SPIs also provide useful practical tools for the design, implementation and revision of effective science–policy interfaces. These lessons regarding CRELE + IT help us understand both when and why SPIs are able to contribute to the pressing social and ecological need to halt biodiversity loss and the further deterioration of ecosystem services.

Emerging Threats to Human Health from Global Environmental Change

Large-scale anthropogenic changes to the natural environment, including land-use change, climate change, and the deterioration of ecosystem services, are all accelerating. These changes are interacting to generate five major emerging public health threats that endanger the health and well-being of hundreds of millions of people. These threats include increasing exposure to infectious disease, water scarcity, food scarcity, natural disasters, and population displacement. Taken together, they may represent the greatest public health challenge humanity has faced. There is an urgent need to improve our understanding of the dynamics of each of these threats: the complex interplay of factors that generate them, the characteristics of populations that make them particularly vulnerable, and the identification of which populations are at greatest risk from each of these threats. Such improved understanding would be the basis for stepped-up efforts at modeling and mapping global vulnerability to each of these threats. It would also help natural resource managers and policy makers to estimate the health impacts associated with their decisions and would allow aid organizations to target their resources more effectively.
