(1) Publish a theoretical manuscript (or group of manuscripts) that articulates our interdisciplinary approach to global ecosystem service valuation (2) Create a database that brings relevant social, economic, and ecological data together in a fully relational format (3) Develop an integrated, dynamic model of ecological and economic systems to more comprehensively evaluate ecosystem services a...
Natural ecosystems benefit human communities by providing ecosystem services such as water purification and crop pollination. Mapping ecosystem service values has become popular, but most are static snapshots of average value. Estimating instead the economic impacts of specific ecosystem changes can better inform typical resource decisions. Here we develop an approach to mapping marginal values...
Although ecological restoration is widely used to combat environmental degradation, very few studies have evaluated the cost-effectiveness of this approach. We examine the potential impact of forest restoration on the value of multiple ecosystem services across four dryland areas in Latin America, by estimating the net value of ecosystem service benefits under different reforestation scenarios....
Since the implementation of market oriented economic reform in 1978, China has been on the track of rapid urbanization. The unprecedented urbanization in China has resulted in substantial cultivated land loss and rapid expansion of urban areas. The cultivated land loss due to urbanization not only threatens food security in China, but has also led to ecological system degradation to which close...
The values of ecosystem services provided by lakes and reservoirs are examined through a meta-analysis on an expanded worldwide database. The study assesses the socio-economic values attributable to the hydrological, biogeochemical and ecological functions provided by lakes and reservoirs (either natural or artificial). Based on the most extensive global database of non-market and market valuat...
The purpose of this paper is to provide a theoretical framework for Maritime Informatics from a serviceoriented ecosystem view. We propose to go beyond the traditional service provider-user dyad view to provide a richer understanding of Maritime Informatics using a case study. Relying upon the ServiceDominant (S-D) logic framework, this paper presents how this service-oriented ecosystem view he...
Using landscape analysis and economic valuation, this article shows how valuation techniques can inform prioritization of private forestland for ecosystem service conservation and highlights the methodological challenges in doing so. We classify forests according to six ecological and social characteristics. If ecosystem service priorities are known a priori, this landscape analysis might be su...
In this exploratory study we use existing in situ qualitative and quantitative data on biophysical and social indicators to compare two contrasting Swedish farming systems (low intensity and high intensity) with regard to ecosystem service supply and demand of a broad suite of services. We show that the value (demand) placed on a service is not necessarily connected to the quantity (supply) of ...
We have developed a social optimization model that integrates wastewater treatment cost function and ecosystem damage cost function. The social optimal abatement level of water pollution is determined by finding the tradeoff between pollution control cost and ecosystem damage. The model is applied to data from the Lake Taihu region in China to demonstrate this tradeoff. A wastewater treatment c...
This paper chose Eastern China area, Central China area, Western China area and Northeast China area as the study object and chose landuse classifications as the basic ecological system unit. It roughly estimated the regional ecological system service value. The theory of ecosystem service value, the method of ecological footprint and ecological carrying capacity are applied to analyze the cros...
