A general relationship between extinction risk and carrying capacity

R&R, Nature Communications. We establish the relationship between a population’s probability of extinction and its carrying capacity as a modified Gompertz curve, a key quantity for assessing conservation status and guiding efforts to understand and mitigate the ongoing biodiversity crisis.

Sacred Ecology: The Environmental Impact of African Traditional Religions

Can religions shape ecosystems? We explore the role religious beliefs play in human-environment interactions by studying African Traditional Religions (ATR), which place forests within a sacred sphere. We focus on the unique case of Benin, whose …

Bringing the Economics of Biodiversity into Policy and Decision-making

R&R, Nature Sustainability. The Target and Cost Analysis (TCA) approach is proposed as a means of reflecting in 25 government appraisals the societal cost of biodiversity losses arising from government investment and regulatory changes. Influenced by how carbon is priced in the UK, the resulting biodiversity price reflects the marginal cost of meeting societal targets, and hence avoids disagreements on the use of willingness to pay measures for this purpose.
