a short letter on science advice for biodiversity in the current issue of Science (Hulme et al. is also here in PDF). This blog post, co-authored with Silke Beck and Christoph Görg of the Helmholz Center for Environmental Research (UFZ) in Leipzig, Germany, provides some additional background and links for those wanting to learn more.]
In the area of biodiversity and ecosystem services efforts to establish an international body to connect expert advice with decision making have coalesced in the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services). Such efforts are sometimes based on a call for an ‘IPCC-like mechanism for biodiversity.’
Even with the recent challenges faced by the Intergovernmental Panel on Climate Change (IPCC), it still provides the role model for global panels, such as for biodiversity and food security. We believe that a formailzed approach to expert advice in the area of biodiversity and ecosystem services must look beyind the IPCC model.
Under the label ‘nested networks’, an interdisciplinary group of scientists at the Helmholtz Centere for Environmental Research at Leipzig has been exploring alternative options on how to produce and govern global environmental assessments. Such explorations also seek to contribute to ongoing debates, including those related to the IPCC reform process and the establishment of the IPBES, which will formally take place in autumn this year.
The Leipzig effort has centered on two international workshops that brought together different group of actors involved in political negotiations and outstanding scholars from different scholarly disciplines and backgrounds. Here is a brief summary, with links to further information:
•In October 2006, a group of highly experienced scientists and practitioners argued that the blueprint suitability of previous assessments for biodiversity governance is very limited because the task, the information needs, nature of the issue at stake and the political contexts mainly differ from former assessments.
As an alternative, they called for a move away from a single, global-level, intergovernmental assessment for assessing different aspects of global change, to more pluralistic, decentralized and heterogeneous ways of interaction they called nested networks. These recommendations played a role in the subsequent consultations about setting up a science-policy platform on biodiversity and ecosystem services.
•In May 2011, a second workshop took place in Leipzig. In a letter to Science published last week, the group of high-level experts called now for moving the focus of the discussion on the IPBES process in two directions:
Second is the need to link IPBES assessment results to nested levels of decision-making at multiple spatial scales (including tackling biodiversity loss ‘on the ground’)
These novel challenges have to be reflected by novel procedures and the governance structures. Provision must be made, for nested, decentralized, largely autonomous sub-global networks, activities, focused on the needs of specific actors in specific decision-making contexts and on enhancing the empowerment of local communities to contribute meaningfully to global policymaking.
