Abstract

Due to the shortage of financial resources for international conservation assistance, the setting of priorities for this assistance is an important issue. A national biodiversity risk assessment index (NABRAI) is constructed to quantify national conservation performances and identify nation states of critical conservation concern. The index, which contains measures of biodiversity stock, flow and response measures, attempts to overcome several weaknesses present in other models used to prioritize nations for conservation assistance. Multivariate analyses of the index as well as economic and biodiversity resources reveal significant positive correlations between the NABRAI values and population density as well as land area exposed to high disturbance intensity. The combination of the multivariate analyses and the interpretation of NABRAI values allows for prioritization of biodiversity risk among the global community and can thus serve as an indicator of current priorities for policy makers. The present study also suggests two methods to incorporate a better understanding of biodiversity risk in models of conservation priorities; by including a wider range of variables and by developing a theoretical foundation for the relationship between the categories of variables used in the model.
