<p>The complex trade-offs of ecosystem services make ecosystem management difficult to achieve win-win goals, especially in a watershed with intensive agriculture. Although a lot of research has been carried out on the types, characteristics and harmonized measures of ecosystem service trade-offs, how to achieve synergistic gain through effective land use management still lacks quantitative Optimization. Combined with models of land use optimization and spatially assessment of ecosystem services, the study build a multi-objective function and a land use optimization method to realize maximization of the total benefit based on the characteristics of ecosystem service trade-off and the driving factors in the Dongting Lake watershed， which is one of the priority areas for ecological protection in China and is also agricultural intensive. First we quantitatively model the water purification service, sediment reduction service and agricultural production using field observation and spatial models of ecosystem services, then the integrated response characteristics of multi-objectives are analyzed according to different land use scenarios based on driven mechanism of ecosystem service trade-offs. Finally the way of optimizing land use allocation and synergetic development of multiple ecosystem services in the watershed is proposed to provide quantitative means for regional land use optimization.</p>

AbstractPoyang Lake is the largest freshwater lake in China and is an important wetland in the world. The scientific assessment of ecosystem service trade-offs in Poyang Lake Basin is of great significance for maintaining regional ecological balance and global biodiversity. This study uses land use as the main data source and the “equivalent factor method” to estimate the ecosystem service value of the Poyang Lake Basin from 1990 to 2015; the study also analyzes the trade-off synergy among ecosystem services. On this basis, land use information was simulated under three scenarios: planning scenario (government policy-oriented), development scenario (economic benefit-oriented), and protection scenario (ecological protection-oriented). The trade-offs and synergies among ecosystem services under different scenarios were evaluated. The results demonstrate that the ecosystem service value for the entire basin steadily increased from 1990 to 2015. The relationships among ecosystem services in the basin were mainly synergistic, and there were few trade-offs. Among the three simulation scenarios, the ecosystem service value was the highest and the trade-offs among ecosystem services were the lowest under the protection scenario, the ecosystem service value was the lowest and the trade-offs among ecosystem services were the highest under the development scenario, and the trade-offs under the planning scenario were between the values of the protection scenario and the development scenario. From the perspective of maximizing the value of ecosystem services and minimizing trade-offs in ecosystem services, the protection scenario is the optimal scenario among the three scenarios.

Abstract The concept of ecosystem services is gaining attention in the context of sustainable resource management. However, it is inherently difficult to account for tangible and intangible services in a combined model. The aim of this study is to extend the definition of ecosystem service trade-offs by using Bayesian Networks to capture the relationship between tangible and intangible ecosystem services. Tested is the potential of creating such a network based on existing literature and enhancement via expert elicitation. This study discusses the significance of expert elicitation to enhance the value of a Bayesian Network in data-restricted case studies, underlines the importance of inclusion of experts’ certainty, and demonstrates how multiple sources of knowledge can be combined into one model accounting for both tangible and intangible ecosystem services. Bayesian Networks appear to be a promising tool in this context, nevertheless, this approach is still in need of further refinement in structure and applicable guidelines for expert involvement and elicitation for a more unified methodology.

Ecosystem markets are proliferating around the world in response to increasing demand for climate change mitigation and provision of other public goods. However, this may lead to perverse outcomes, for example where public funding crowds out private investment or different schemes create trade-offs between the ecosystem services they each target. The integration of ecosystem markets could address some of these issues but to date there have been few attempts to do this, and there is limited understanding of either the opportunities or barriers to such integration. This paper reports on a comparative analysis of eleven ecosystem markets in operation or close to market in Europe, based on qualitative analysis of 25 interviews, scheme documentation and two focus groups. Our results indicate three distinct types of markets operating from the regional to national scale, with different modes of operation, funding and outcomes: regional ecosystem markets, national carbon markets and green finance. The typology provides new insights into the operation of ecosystem markets in practice, which may challenge traditionally held notions of Payment for Ecosystem Services. Regional ecosystem markets, in particular, represent a departure from traditional models, by using a risk-based funding model and aggregating both supply and demand to overcome issues of free-riding, ecosystem service trade-offs and land manager engagement. Central to all types of market were trusted intermediaries, brokers and platforms to aggregate supply and demand, build trust and lower transaction costs. The paper outlines six options for blending public and private funding for the provision of ecosystem services and proposes a framework for integrating national carbon markets and green finance with regional ecosystem markets. Such integration may significantly increase funding for regenerative agriculture and conservation across multiple habitats and services, whilst addressing issues of additionality and ecosystem service trade-offs between multiple schemes.

Specific forest restoration aims to maximum ecosystem services (ESs); however, the complex trade-offs among ecosystem services pose considerable challenges for fulfilling such goals. Based on forest restoration on Hainan Island, China, we integrated spatially explicit models of ecosystem services and spatial prioritization techniques based on the efficiency frontier between habitat quality and plantation revenue to analyze the impacts of decision-makers’ preferences on optimal configurations of forest restoration. We then investigated the effects of different optimal restoration schemes on water purification, soil retention, carbon sequestration, and coastal hazard mitigation. Based on our results, plantation revenue and habitat quality exhibited an obvious trade-off during the process of restoration. Forest restoration patterns also varied with the degree of preference for plantation yield or habitat quality, indicating that understanding ecosystem service tradeoffs can support the optimal selection of forest restoration schemes under different preferences. However, when the values of multiple ecosystem services associated with forest restoration were considered (e.g., water purification, soil retention, carbon sequestration, and coastal hazard mitigation), the optimal solution choice varied. Our results suggest the application of the efficiency frontier can deepen quantitative understanding of ecosystem service trade-offs, and the addition of multi-benefit evaluation based on optimal solutions can provide a more detailed and broader picture of forest restoration plans. Integrated efficiency frontier assessment with the valuation of ecosystem services associated with forest restoration provides a quantitative approach for optimal forest restoration, which can be applied in broad forest restoration programs.

Rapid industrialization and urbanization have brought dramatic changes to land use structure and layout but have caused several negative impacts on the ecosystem and environment. Increasing the supply of ecosystem services (ESs) in important ecological regions through land use optimization is one strategy that must be seriously considered in land use planning. However, existing land use optimization primarily focuses on economic outcomes, and is difficult to adapt to the practical needs of ecological civilization construction in China. Therefore, we formulated a framework that links ESs to land use decisions by combining policy analyses, multi-scenarios and integrated modelling. The paper is organized into three main parts. First, we conduct a systematic literature review to land use change (LUCC), ESs, and their relationship. Next, we build on insights from the literature review to develop a conceptual framework that integrates ESs into land use optimization. The framework includes a quantitative analysis and spatial allocation of land use. For the quantitative analysis, in addition to considering the development trends, we set ESs to achieve national requirements. Then, an optimized scenario targeted at the maximum ecosystem service value was built. For the spatial allocation, we combined multi-layer perception (MLP) and cellular automaton (CA) and developed an MLP-CA model independently. Last, an empirical study of the proposed framework was implemented in Puge County, China. Our results provide a new technical tool for the layout of optimal land use under the constraint of ecological protection policies and provides a way to address trade-offs between ecological, social, and economic values.

The Relationship

<p>The Qinghai-Tibetan Plateau (QTP) is a “sensor” and “sensitive area” for climate change in Asia and even the northern hemisphere, and its soil ecosystem services are vital components to all aspects of life in the region and support ecosystem functions and services. Understanding the distribution of regional ecosystem services, the relationship among ecosystem services and the influencing factors is an important prerequisite for the protection and optimization of the ecosystem on the QTP. This study quantitatively analyzed the spatio-temporal distribution and interrelationship of multiple ecosystem services such as soil retention (SR) service, water yield (WY) service, habitat quality (HQ) service, crop supply (CS) and livestock supply (LS) services in the Qinghai-Tibet Plateau (QTP) based on InVEST model, statistical and NPP data. Besides, we explored the influences of temperature, elevation, population density, land use and land cover on the relationship of ecosystem services and put forward the corresponding optimization strategy based on ecosystem services perspective. We found that SR, WY and HQ decreased from the southeast to the northwest, regulating services-supporting services are mainly identified as synergies and CS-HQ and CS-LS are manifested as trade-offs. In addition, natural factors (temperature, elevation) influence the distribution of CS and the level of significance of LS, natural factors and the land-use/land-cove affect the shift in the trade-offs and synergies between regulating services and supporting services, and population density mainly affects the relationship between supporting services and other types of services. Providing that the scale effect of ecosystem service relationships in the QTP, we divided the livestock supply collaborative promotion area, the crop-livestock tradeoff optimization area and the multi-ecosystem service optimization area, then put forward specific suggestions at the city scale. This study could be a step forward to optimizing the balance between provisioning services and supporting services or regulating services in the QTP and implementing ecosystem protection policies effectively.</p>
