An Ecosystem Service Value Model to Quantify Eco-environment Cost

With the development of society, ecological environmental protection has become more and more important. In this paper, an Ecosystem Service Value Model (ESVM) was developed to quantify the value of all types of ecosystem services. Through the ecosystem service value evaluation index system we established, we determined ecosystem service value equivalent factors of different ecosystem services. Then we combine the baseline value of the ecosystem service value equivalent factor to determine the ecosystem service value per unit area of different ecosystems. The amount of ecological service value reduction can be calculated with the amount of change in ecosystem area caused by land use projects. Ecological costs are equal to the reduction in the value of ecosystem services. The true economic cost of land use project consists of two parts: project construction cost and ecological cost. The model established in this paper considers the effects of time changes. And the introduction of dynamic adjustment of biomass changes and dynamic adjustment of currency changes make the model more adaptable to time changes. The research can evaluate the value of ecosystem services, which promotes the harmonious development of human and ecological environment

Scenario Simulation of Ecosystem Services Value Changes and Its Implication for Sustainability Development Goals

This study quantified the effect of future land use/ land cover changes on ecosystem service values under different scenarios in Mekelle city region for the year 2030. The study utilized land use/land cover changes data of the year 2019 and predicted LULC changes for the year 2030. Identification of the driving forces, was the most important step in predicting the future LULC and was performed using the cellular automata models in CLUDMondo which is a future land use simulation model by coupling human and the natural effects. Scenarios were made under business as usual, implementation of PES schemes and spatial planning. In business-as-usual scenario, it was observed that ecosystem services value will decline by 2030 from the base year of 2019, whereas under spatial planning scenario, the ecosystem service value will increase by 5.2%. Such results can serve as useful information in policy formulation in developing land use options, which help enhance ecosystem service value in future. Therefore, special attention should be given to the rehabilitation of ecosystems, the protection of the remaining natural vegetation and water bodies. Overall, these results provide useful inputs to planners to adopt eco-friendly policies to achieve sustainable development goals.

Ecosystem services values at risk in the Atlantic coastal zone due to sea-level rise and socioeconomic development

Uncertainties about the future extent of sea-level rise (SLR) and socioeconomic development will determine the future of coastal ecosystem services and values. This study analyzes the joint impact of flooding and socioeconomic development on the future ecosystem services and values in the Atlantic coastal zone by 2100. To this end, flood probability maps (using the Uncertainty Bathtub Model; uBTM) and local ecosystem service value (ESV) estimates (using meta-analytic based global ecosystem service value functions for Provisioning, Regulating & maintenance, and Cultural ecosystem services across 12 biomes) are derived for a wide combination of Representative Concentration Pathway (RCP) and Shared Socioeconomic Pathways (SSP) scenarios to obtain future values of coastal ecosystem services (ES). Results show that the higher potential of ESV at risk is associated with RCP 8.5 and SSP5, i.e. the scenario associated with a narrative related to fossil-fueled development. For this scenario, by 2100, the coastal zone with the highest probable losses in Provisioning ESV is Europe (∼5.9 € billion/year), for Regulating & maintenance ESV this is North America (∼6.0 € billion/year) and for Cultural ESV this is South America (∼21.3 € billion/year). Countries facing highest relative risk of losing Provisioning ESV are the Netherlands (10.6 %), United States (7.4 %), and Mauritania (5.8 %). For Regulating & maintenance ESV, the top 3 countries impacted are Mauritania (17.6 %), the Netherlands (10.0 %) and Argentina (8.0 %). For Cultural ESV, the countries are Mexico (19.0 %), Denmark (18.1 %) and Sweden (15.6 %). Changes in ESV are exponentially related to flood risk and economic growth, such that small changes in flood or income lead to large changes in ESV. Unlike previous studies, the ESV functions used are dependent on time and local factors, such as population and income. Although population and income growth result in an increase in ESV, it also emphasizes the ecosystem service values at risk. Thus, sea-level rise and socioeconomic changes impact ecosystem services and values – directly affecting the well-being of the world population. The unequal distribution of coastal ecosystem service value losses across continents and countries highlighted in this work is important to identify what values are at risk and for whom. Adaptation measures and strategies can, in turn, be defined

The Economic Benefits of Cleaning Up the Chesapeake

Information on the economic benefits of environmental improvement is an important consideration for anyone (firms, organizations, government agencies, and individuals) concerned about the cost-effectiveness of changes in management designed to achieve that improvement. In the case of the Chesapeake Bay TMDL (Total Maximum Daily Load of nitrogen, phosphorus, and sediment), these benefits would accrue due to improvements in the health, and therefore productivity, of land and water in the watershed. These productivity changes occur both due to the outcomes of the TMDL and state implementation plans, also known as a "Chesapeake Clean Water Blueprint" itself (i.e., cleaner water in the Bay) as well as a result of the measures taken to achieve those outcomes that have their own beneficial side effects. All such changes are then translated into dollar values for various ecosystem services, including water supply, food production, recreation, aesthetics, and others. By these measures, the total economic benefit of the Chesapeake Clean Water Blueprint is estimated at $22.5 billion per year (in 2013 dollars), as measured as the improvement over current conditions, or at$28.2 billion per year (in 2013 dollars), as measured as the difference between the Clean Water Blueprint and a business-as-usual scenario. (Due to lag times—it takes some time for changes in land management to result in improvements in water quality, the full measure of these benefits would begin to accrue sometime after full implementation of the Blueprint.) These considerable benefits should be considered alongside the costs and other economic aspects of implementing the Chesapeake Clean Water Blueprint

Dam failure environmental standards in China based on ecosystem service value

Dam failure risk standards are the foundation of risk decision-making for dam managers. However, as an important component of dam failure risk standards, there are currently no unified environmental risk standards. Drawing on research ideas of ecological economics on ecosystem service values and equivalent factor methods, this study quantified environmental values and effectively connected environmental standards with existing standards using the ALARP principle and the F-N curve. Considering the differences in environmental and economic conditions in different regions, a risk preference matrix was constructed to determine the risk preference of each region and formulate the dam failure environmental risk standards for China. This study presents a preliminary exploration of the formulation of dam failure environmental risk standards, providing new methods and ideas for subsequent research

Reconfiguring an Irrigation Landscape to Improve Provision of Ecosystem Services

Over-allocation of fresh water resources to consumptive uses, coupled with recurring drought and the prospect of climate change, is compromising the stocks of natural capital in the world’s basins and reducing their ability to provide ecosystem services. To combat this, governments world wide are making significant investment in efforts to improve sharing of water between consumptive uses and the environment, with many investments centred on modernisation of inefficient irrigation delivery systems, and the purchase of water by government for environmental flows. In this study, spatial targeting was applied within a cost-benefit framework to reconfigure agricultural land use in an irrigation district to achieve a 20% reduction in agricultural water use to increase environmental flows and improve the provision of other ecosystem services. We demonstrate using spatial planning and optimisation models that a targeted land use reconfiguration policy approach could potentially increase the net present value of ecosystem services by up to AUS$463.7m. This provides a threshold level of investment that would be justified on the basis of benefits that the investment produces. The increase in ecosystem services include recovering 61 GL of water for environmental flows, the sequestration of 10.6m tonnes of CO2-e/yr, a 13 EC (?S/cm) reduction in river salinity, and an overall 24$68.7m in economic returns to agriculture which may be only marginally offset by the increased value of ecosystem services resulting from the return of 61 GL of water to the environment.landscape planning, geographic information systems, cost-benefit analysis, irrigation, climate change, water management, spatial targeting, environmental valuation

A spatially explicit and quantitative vulnerability assessment of ecosystem service change in Europe

Environmental change alters ecosystem functioning and may put the provision of services to human at risk. This paper presents a spatially explicit and quantitative assessment of the corresponding vulnerability for Europe, using a new framework designed to answer multidisciplinary policy relevant questions about the vulnerability of the human-environment system to global change. Scenarios were constructed for a range of possible changes in socio-economic trends, land uses and climate. These scenarios were used as inputs in a range of ecosystem models in order to assess the response of ecosystem function as well as the changes in the services they provide. The framework was used to relate the impacts of changing ecosystem service provision for four sectors in relation to each other, and to combine them with a simple, but generic index for societal adaptive capacity. By allowing analysis of different sectors, regions and development pathways, the vulnerability assessment provides a basis for discussion between stakeholders and policymakers about sustainable management of Europe¿s natural resource

Critique and transformation: On the hypothetical nature of ecosystem service value and its neo-Marxist, liberal and pragmatist criticisms

Ecosystem service valuation (ESV) attempts to transform the opposition of human economic necessity and ecological conservation by valuing the latter in terms of the services rendered by the former. However, despite a number of ESV-inspired sustainability initiatives since the 1990s, global ecological degradation continues to accelerate. This suggests that ESV has fallen far short of its goals of sustainable social transformation—a failure which has generated considerable criticism. This paper reviews three prominent lines of ESV criticism: 1) the neo-Marxist criticism, which emphasizes the “fictitious” character of ecosystem commodities; 2) the liberal criticism through Friedrich Hayek\u27s concept “scientistic objectivism”; and 3) the pragmatist criticism of “value monism”. Although each form of criticism provides insight into the limitations of ESV, all share ESV\u27s inability to discern what kind of social transformation is possible. Unable to provide an account of their own immersion in social and historical context, these approaches operate in the hypothetical. In light of these shortcomings, this paper advances a critical theory approach, which we contend provides conceptual tools uniquely well-suited to more adequately address the question of social transformation

Literature review and database on ecosystem service valuation studies for Kenya and Vietnam

This review aimed to compile a database of values for ecosystem services in Kenya and Vietnam. The search period for literature was from July 15 to September 15, 2022. The Scopus database and the Ecosystem Services Valuation database were used to identify relevant papers. A total of 162 papers are in the database, with 76 papers about Kenya and 86 about Vietnam. There are 1573 values in the database, 784 for Kenya and 789 for Vietnam. The data collected from each paper in the database included the type of biome, ecosystem service, raw data for the ecosystem service value and the method of ecosystem service value estimation. The variables for which data was collected were based on The Economics of Ecosystems and Biodiversity (TEEB) framework. The TEEB framework allows for the categorization of biomes, sub biomes and types of ecosystem services to be standardized. The ecosystem services are divided into three levels of classification: ecosystem services, ecosystem sub-services and ecosystem sub-sub-services

Ecosystem Service Value of the Mixed Land Use Pattern in Asia: Thailand’s Experience

The rapid increase in economic development and urbanisation along the Eastern Economic Corridor (EEC) of Thailand has accelerated the change in its ecosystem service value (ESV), leading to the demand for related analysis to ensure sustainable growth in the area. The aim of this study is to: (1) evaluate the land use change in Chonburi Province; the most urbanised city in the EEC of Thailand between 2006 and 2016, and (2) assess the land use change impact on ESV. Secondary data from land use maps for 2006 and 2016 was used to evaluate land use change and its impact on ESV using the land use transition matrix, land use dynamic degree, and the benefit transfer method. Urban and built-up land use were found to dominate other use types. The top three highest annual rates of land use change were found in water bodies, rangeland, and urban and built-up land. The ESV in 2016 was found to be 1.31% higher than for 2006. The ecosystem service functions (ESFs) contributing to the increase in ESV were waste treatment, hydrological regulation, climate regulation and recreation and service culture. Future land use planning should focus on increasing wetlands and protecting agricultural land in the study area since these contribute to the highest ESV. In addition, it is essential to balance economic development with ecological enhancement
