Towards a comprehensive sustainability methodology to assess anthropogenic impacts on ecosystems : review of the integration of Life Cycle Assessment, Environmental Risk Assessment and Ecosystem Services Assessment Ghent University Flanders Marine Institute University of Antwerp

Laura Vittoria De Luca Pena, Sue Ellen Taelman, Nils Préat, Lieselot Boone, Katrien Van der Biest, Marco Custódio, Simon Hernandez Lucas, Gert Everaert, Jo Dewulf
Nowadays, a variety of methodologies are available to assess local, regional and global impacts of human activities on ecosystems, which include Life Cycle Assessment (LCA), Environmental Risk Assessment (ERA) and Ecosystem Services Assessment (ESA). However, none can individually assess both the positive and negative impacts of human activities at different geographical scales in a comprehensive manner. In order to overcome the shortcomings of ...

Ecosystem Service Valuations of Mangrove Ecosystems to Inform Decision Making and Future Valuation Exercises Vrije Universiteit Brussel KU Leuven

Nibedita Mukherjee, William J. Sutherland, Lynn Dicks
The valuation of ecosystem services is a complex process as it includes several dimensions (ecological, socio-cultural and economic) and not all of these can be quantified in monetary units. The aim of this paper is to conduct an ecosystem services valuation study for mangroves ecosystems, the results of which can be used to inform governance and management of mangroves. We used an expert-based participatory approach (the Delphi technique) to ...

How to measure ecosystem stability? An evaluation of the reliability of stability metrics based on remote sensing time series across the major global ecosystems KU Leuven

Wanda De Keersmaecker, Stef Lhermitte, Olivier Honnay, Jamshid Farifteh, Ben Somers, Pol Coppin
Increasing frequency of extreme climate events is likely to impose increased stress on ecosystems and to jeopardize the services that ecosystems provide. Therefore, it is of major importance to assess the effects of extreme climate events on the temporal stability (i.e., the resistance, the resilience, and the variance) of ecosystem properties. Most time series of ecosystem properties are, however, affected by varying data characteristics, ...

Integrating community assembly and biodiversity to better understand ecosystem function: the Community Assembly and the Functioning of Ecosystems (CAFE) approach KU Leuven

Steven Declerck
The research of a generation of ecologists was catalysed by the recognition that the number and identity of species in communities influences the functioning of ecosystems. The relationship between biodiversity and ecosystem functioning (BEF) is most often examined by controlling species richness and randomising community composition. In natural systems, biodiversity changes are often part of a bigger community assembly dynamic. Therefore, ...

Developing priority variables ("ecosystem Essential Ocean Variables" - eEOVs) for observing dynamics and change in Southern Ocean ecosystems KU Leuven

Anton Van de Putte
© 2016 The Authors. Reliable statements about variability and change in marine ecosystems and their underlying causes are needed to report on their status and to guide management. Here we use the Framework on Ocean Observing (FOO) to begin developing ecosystem Essential Ocean Variables (eEOVs) for the Southern Ocean Observing System (SOOS). An eEOV is a defined biological or ecological quantity, which is derived from field observations, and ...
