National ecosystem assessments form an essential knowledge base for safeguarding biodiversity and ecosystem services. We analyze eight European (sub-)national ecosystem assessments (Portugal, United Kingdom, Spain, Norway, Flanders, Netherlands, Finland, and Germany) and compare their objectives, political context, methods, and operationalization. We observed remarkable differences in breadth o...
Ecosystems are commonly exploited and manipulated to maximize certain human benefits. Such changes can degrade systems, leading to cascading negative effects that may be initially undetected, yet ultimately result in a reduction, or complete loss, of certain valuable ecosystem services. Ecosystem-based management is intended to maintain ecosystem quality and minimize the risk of irreversible ch...
1. Forests (natural but also human-made or modified) are among the most important providers of ecosystem services for the whole world. 2. Based on scientific evidence, it is certain that: (a) Ecosystem services are essential to the survival of human beings. (b) Forest ecosystems operate and provide services on such a grand scale and in such intricate and little-explored ways that most cannot ef...
1 Balkanized research in ecological engineering revealed by a bibliometric analysis of earthworms and ecosystem services. Abstract Energy crisis, climate changes and biodiversity losses have reinforced the drive for more ecologically-based approaches for environmental management. Such approaches are characterized by the use of organisms rather than energy-consuming technologies. Although earthw...
In our increasingly technological society, people give little thought to how dependent they are on the proper functioning of ecosystems and the crucial services for humanity that flow from them. Ecosystem services are “the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfill human life” (Daily 1997); in other words, “the set of ecosys...
Ecosystem services are benefits that people obtain from ecosystems. Soil retention is one of the most important ecosystem services. The capacity of ecosystem to maintain soil can be estimated by quantifying this services. In this study, version 3.0.0 of the InVEST software was used to map this ecosystem service in the eastern part of Gorgan-Rud watershed. The InVEST model employs the Universal ...
Purchases of private land for conservation are common in California and represent an alternative to regulatory land-use policies for constraining land use. The retention or enhancement of ecosystem services may be a benefit of land conservation, but that has been difficult to document. The InVEST toolset provides a practical, low-cost approach to quantifying ecosystem services. Using the toolse...
Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension of ecosystem services, despite being considered a research priority. We examined how ecosystem service bundles and trade-offs emerge from diverging social preferences toward...
Changes in land use can cause significant changes in the ecosystem structure and process variation of ecosystem services. This study presents a detailed spatial, quantitative assessment of the variation in the value of ecosystem services based on land use change in national nature reserves of the Ningxia autonomous region in China. We used areas of land use types calculated from the remote sens...
