Having an adequate and extensively recognized resource governance system is essential for the conservation and sustainable use of crop genetic resources in a highly populated planet. Despite the widely accepted importance of agrobiodiversity for future plant breeding and thus food security, there is still pervasive disagreement at the individual level on who should own genetic resources. The aim of the article is to provide conceptual clarification on the following concepts and their relation to agrobiodiversity stewardship: open access, commons, private property, (...) state property and common heritage of humankind. After presenting each property regime, we will examine whether and how these incentivize the conservation, improvement and sharing of crop genetic resources, and conclude by defending a mixed property regime.

The use of target baselines or reference states for conservation and restoration has become increasingly problematic and impractical, due to rapid environmental change, the paradigm shift in ecology from a static to a dynamic view of nature, and growing awareness of the role of cultural traditions in the reconstruction of baselines. The various responses to this crisis of baselines will to a significant extent determine the future direction of nature conservation. Although some hold onto traditional baselines and others try to (...) refine or redefine the reference concept, the debate is currently dominated by two widely diverging reactions to the crisis: while the so-called 'new environmentalists' or 'new conservationists' declare the whole baseline notion obsolete, replacing a backward-looking approach with a forward-looking one, the 're-wilders' push the baseline back to a deeper, more distant past. This article provides a critical assessment of the debate on these conversation options, with a special focus on the differences between Old World and New World perspectives. (shrink)

This paper is about the practice of evaluating ecosystems on the basis of the cultural services they provide. My first aim is to assess the various objections that have been made to this practice. My second is to argue that when particular places are integral to people’s lives, their value cannot be adequately conceived in terms of the provision of cultural ecosystem services. It follows, I conclude, that the ecosystem services framework can provide only a very limited account of the (...) value of places. (shrink)
