Economics serving society

(October 15) Climate and Biodiversity: Interdisciplinary Workshop

Climate change and biodiversity loss have emerged as key environmental challenges. They are often treated separately in academic research, although strong interlinkages have been identified: land use patterns affect both directly, biomass (both land and marine) is a key carbon sink, climate change is a likely booster of mass extinction, agro-food systems have strong impacts on biodiversity, on wild and raised animal welfare, and CO2 emissions. An even deeper link between the two topics comes from the growing calls to shed the anthropocentric perspective and develop a valuation of ecosystem services in which non-human species are seen not as instruments to human welfare but as co-users of spaceship Earth.

This one-day workshop brings together specialists of climate policy, biodiversity, food and animal welfare from economics, philosophy and environmental sciences, to explore policy issues at the interface of climate change and biodiversity.
