KOSMOS Workshop 2017

 

On the 30th-31st of March 2017, the Geomatics Lab has hosted the Workshop "Remote Sensing of Ecosystem Functioning", bringing together a group of researchers from GEO BON (Group on Earth Observations Biodiversity Observation Network) Ecosystem Function Working Group. On the 30th the workshop had the form of a mini-conference with public talks on the topic. Numerous interested students and researchers attended the talks.

Workshop description

In times of global change, international societal targets were defined to help prevent and mitigate losses in global biodiversity. In order to monitor progresses towards these targets, it is necessary to monitor biodiversity globally and in a standardized manner. This leads to the definition of Essential Biodiversity Variables (EBVs) relating to biodiversity ranging from genes to ecosystems. Ecosystem functioning is a highly relevant EBV class, as it enhances our knowledge and understanding of ecosystem processes and its change. It comprises variables such as net primary productivity, secondary productivity, nutrient retention, and disturbance regime. The global characterisation and monitoring of ecosystem functioning, while being a field of ongoing research, is only possible through remote sensing approaches and thus requires a deep knowledge on both the remote sensing and ecosystem ecology disciplines.

 

Particularly, the characterisation of ecosystem function, its heterogeneity or diversity, based on the EBVs framework concept, may provide unique information e.g. when compared to existing (taxonomic/structural) ecological maps. This effort could be used to inform conservation initiatives such as the International Union for Conservation of Nature (IUCN) Red List of Ecosystems or to report progress towards the Convention on Biological Diversity (CBD) Aichi Targets. Furthermore, it could provide critical information on species habitats and ecosystem services.

 

This workshop aimed at contributing towards setting up protocols and workflows for deriving EBVs related to ecosystem functioning, thus filling a present research gap. It joined an interdisciplinary group of internationally leading researchers from several institutions from Germany, United States of America, The Netherlands, Switzerland, Spain, Portugal, Italy and France. The expertise of this group ranges from remote sensing to ecology, with a focus on functional traits and ecosystem functioning characterization. This initiative may serve as a stepping stone on the actual development of globally valid EBVs at a critical time when it is necessary to move away from concept definition towards actual implementation of functioning EBVs, useful for reporting global biodiversity change.
