Humans and the ecosystem services they depend on are threatened by climate change. Places with high or growing human population as well as increasing climate variability, have a reduced ability to provide ecosystem services just as the need for these services is most critical. A spiral of vulnerability and ecosystem degradation often ensues in such places. We apply different global conservation...
The deterioration of alpine grassland has great impact on ecosystem services in the alpine region of Qinghai-Tibetan Plateau. However, the effect of grassland degradation on ecosystem services and the consequence of grassland deterioration on economic loss still remains a mystery. So, in this study, we assessed four types of ecosystem services following the Millennium Ecosystem Assessment class...
Natural ecosystems provide society with important goods and services. With rapidly increasing populations and excessive utilization of natural resources, humans have been enhancing the production of some services at the expense of others. Although the need for certain trade-offs between conservation and development is urgent, having only a small number of efficient methods to assess such trade-...
Ecosystem services are the benefits that mankind obtains from natural ecosystems. Here we identify the key services provided by the Southern Ocean. These include provisioning of fishery products, nutrient cycling, climate regulation and the maintenance of biodiversity, with associated cultural and aesthetic benefits. Potential catch limits for Antarctic krill (Euphausia superba Dana) alone are ...
This Distributed Graduate Seminar (DGS) aims to synthesize current ecological information on the role that biodiversity in agricultural landscapes (agrobiodiversity) plays in providing ecosystem services. In recent years numerous studies aimed at examining the importance of agroecosystems to the conservation of biodiversity have been published. These studies focus on identifying the types of ag...
Considerable effort has been directed into separate but related research foci—the study of ecosystem services and participatory mapping methods. The two research foci intersect in the mapping of placebased values, an operational form of social values for ecosystem services that uses public participation GIS (PPGIS) methods. The social valuation of ecosystem services through participatory mappin...
After decades of research and demonstration, use of ecosystem services in decision making is being translated into policy guidance for practitioners.1 In October 2015, the U.S. Executive Offices of the President—the Office of Management and Budget, the Council on Environmental Quality, and the Office of Science and Technology Policy—released a memo “Incorporating Ecosystem Services into Federal...
