Am Donnerstag, 29. Mai, wurde auf der 9. Vertragsstaatenkonferenz (COP9) des Internationalen Übereinkommens zur Biodiversität (CBD) in Bonn ein Bericht zur Abschätzung des ökonomischen Werts der ökologischen Vielfalt - "TEEB - The Economics of Ecosystems and Biodiversity" - vorgestellt.
Nach den Worten seines Hauptautors Pavan Sukhdev liefert bereits der nun vorliegende Zwischenbericht "eine umfassende und überzeugende ökonomische Begründung für den Schutz der Biodiversität". Die Untersuchung wurde 2007 durch Bundesumweltminister Gabriel und EU-Kommissar Dimas initiiert und wird bis zum Jahr 2010 andauern. An der Koordination und der Erstellung des Zwischenberichtes waren neben zahlreichen internationalen Experten auch Wissenschaftler des UFZ beteiligt.
The Economics of Ecosystems and Biodiversity- TEEB
At CBD COP 9 today, 29th May, a report setting out a "comprehensive and compelling economic case for the conservation of biodiversity" was presented by the report's author Mr. Pavan Sukhdev. The work was launched in 2007 by Minister Sigmar Gabriel of Germany and Stavros Dimas the Commissioner responsible for Environment in the European Commission, to promote a better understanding of the true economic value of the benefits we receive from nature. The report presented today is the interim report of the work which will continue in 2009 and 2010.
Mr Sukhdev, a senior figure in Deutsche Bank, said that the interim report showed "we are trying to navigate uncharted and turbulent waters with an old and defective economic compass and that this was affecting our ability to forge a sustainable economy in harmony with nature."What is the Issue?
o 60% of coral reefs could be lost - even by 2030 - through fishing, pollution, diseases, invasive alien species, and coral bleaching due to climate change.
Current trends on land and in the oceans demonstrate the severe dangers that biodiversity loss poses to human health and welfare. Climate change is exacerbating this problem. And again, as with climate change, it is the world's poor who are most at risk from the continuing loss of biodiversity. They are the ones most reliant on the ecosystem services which are being undermined by flawed economic analysis and policy mistakes.Biodiversity Protection and Questions of Equity and Ethics
Incorporating the true value of biodiversity and ecosystem services into policy decisions is the ultimate aim of the work being carried out by Pavan Sukhdev and his team. There are ethical choices involved in particular between present and future generations and between people in different parts of the world.What is the Economic Cost of the Loss of Biodiversity and Ecosystem Services?
As indicated above, this is a conservative estimate: it is partial, excluding some ecosystem services, some negative feedback effects of these losses on GDP growth are not fully accounted for, and the values do not account for non-linearities and threshold effects in ecosystem functioning. However, these first results suggest that the socio-economic impacts of biodiversity loss can be substantial. More work will be needed in Phase II of the study to consolidate a large-scale assessment of the costs of losses of the main types of ecosystems worldwide and to compare them with the costs of policies to better protect biodiversity and ecosystems.The Next Steps
Phase II of the work will examine in greater detail how we can improve our economic models and policies to secure the flow of ecosystem services (nature's benefits), particularly food and water in a transparent and fair way. This will not only protect biodiversity, but will also improve the well-being of our present generation and the generations to come.Key Additional Information

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
