Economy and Ecology: Reconciling economic development and the conservation of Europe’s Biodiversity
Special Issue on ALARM Project Explores Europe’s Ecological Futures
Leipzig/Helsinki/Lund. As European leaders struggle to avert a second recession a new study finds that future economic growth and the sustenance of the continent’s ecosystem services may be incompatible, unless political priority setting focusses on sustainable development with a special emphasis on biodiversity conservation. The research, published in a special issue of Global Ecology and Biogeography, combines socio-economic, land use, climate and biodiversity models with other approaches to consider three possible routes for the future of Europe’s economy. The scientists explore the multiple impacts on biodiversity within the next century.

The special issue is edited by Josef Settele and Joachim Spangenberg from the Helmholtz Centre for Environmental Research - UFZ/Germany, Timothy Carter from the Finnish Environment Institute - SYKE/Finland, and Martin Sykes from the University of Lund/Sweden. It combines and integrates the outcomes of scenario research of the ALARM project (Assessing LArge-scale environmental Risks for biodiversity with tested Methods; www.alarmproject.net), which brought 250 scientists from 68 partner organisations of 35 countries together to explore potential future risks to Europe’s as well as global biodiversity and ecosystem services.
"Scenarios can provide a comprehensive view of plausible - not necessarily probable - future developments, and they can deal with complexity. This way they serve as a means to explore the possible future outcomes of decisions taken - or not taken - now" says Joachim Spangenberg, who led the scenario group of the project.
Within ALARM, scenarios developed are broad pictures of possible futures aiming to derive information on risks to biodiversity from a diverse range of factors during the 21st century. The three core scenarios are BAMBU (‘Business As Might Be Usual’), an extrapolation of current policy trends, and two alternative policy options, GRAS (‘GRowth Applied Strategy’) simulating a policy of deregulation and globalization, and SEDG (‘Sustainable European Development Goal’), a sustainable development policy scenario.
ALARM scenarios and the IPCC
The ALARM scenarios build upon different global scenarios developed by the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES), from which climate, economic and land use scenarios were derived for Europe. These, in turn, provided a reference base for developing vegetation, plant invasion and chemical deposition scenarios as well and for projecting future ranges of interacting species. All aspects of the scenario building process are dealt with in the special issue (see list of contributions, below).
"The SRES scenarios are due to be superseded by a new set of global socio-economic, technological, land-use, emissions and climate scenarios developed by the international research community ahead of the IPCC Fifth Assessment Report" adds Tim Carter. According to Martin Sykes, "this however should not imply that the ALARM scenarios will become invalid; rather the new scenarios can be regarded as complementary, providing richer and more regionally specific socio-economic characterizations than the SRES, some of which are still perfectly consistent with the ALARM biodiversity-orientated information."
Tim Carter, who is also one of the authors of the forthcoming IPCC report, concludes that "it will be an important task of the IPCC AR5 to assess how the new scenarios relate to SRES and to some other global scenario exercises. From this analysis it should then be possible to gauge the lasting value of the ALARM scenarios for continued application in the future."
Will EU policies be able to stop the loss of biodiversity?
"The scenarios tell us that the extension of current EU policies will act as a brake on current trends by slowing down the loss of biodiversity in many cases and in most biomes, but it will not be capable of halting or of reversing the loss. Liberalization has the effect of accelerating biodiversity loss across the board, with few exceptions. A coherent sustainability scenario is clearly the most effective at preserving biodiversity, but the variant tested here still does not halt losses in all cases", states Ingolf Kühn of UFZ, who also contributed to several papers of the special issue.
Joachim Spangenberg summarizes: "Generally, current EU policies for protecting biodiversity appear to be insufficient to reverse ongoing losses. Coherent sustainability strategies are effective at conserving biodiversity, but in order to reverse losses, the official objective of the new EU biodiversity policy, measures would need to be introduced that extend even beyond the steps tested in the ALARM sustainability scenario." "Only time will tell whether the ALARM scenarios will succeed in offering useful insights to a wider constituency of users" said Josef Settele, the ALARM coordinator and another author currently contributing to the IPCC Fifth Assessment Report. "Scenarios can play a valuable role in providing coherence to studies of future global change. This is especially true when such studies address multiple objectives and draw upon diverse disciplines and research traditions as we see in this special issue."
