Social Dimensions of Fertility Behavior and Consumption Patterns in the Anthropocene. . PNAS 117 (12):6300–6307.

We consider two aspects of the human enterprise that profoundly affect the global environment: population and consumption. We show that fertility and consumption behavior harbor a class of externalities that have not been much noted in the literature. Both are driven in part by attitudes and preferences that are not egoistic but socially embedded; that is, each household’s decisions are influenced by the decisions made...

Integrating the Water Planetary Boundary With Water Management From Local to Global Scales

Zipper, S. C., Jaramillo, F., Wang‐ Erlandsson, L., Cornell, S. E., Gleeson, T., Porkka, M., et al.. 2020. Integrating the Water Planetary Boundary With Water Management From Local to Global Scales. Earth's Future 8, e2019EF001377.

The planetary boundaries framework defines the “safe operating space for humanity” represented by nine global processes that can destabilize the Earth System if perturbed. The water planetary boundary attempts to provide a global limit to anthropogenic water cycle modifications, but it has been challenging to translate and apply it to the regional and local scales at which water problems and management typically occur. We develop...

Review of the research knowledge and gaps on fish populations, fisheries and linked ecosystems in the Central Arctic Ocean (CAO)

Snoeijs-Leijonmalm, P., H. Flores, F. Volckaert, B. Niehoff, F. L. Schaafsma, J. Hjelm, J. Hentati-Sundberg, S. Niiranen, A.-S. Crépin, H. Österblom. 2020. Review of the research knowledge and gaps on fish populations, fisheries and linked ecosystems in the Central Arctic Ocean (CAO). European Commission, Executive Agency for Small and Medium-sized Enterprises (EASME).

This report presents a review of the research knowledge and gaps on fish populations, fisheries and linked ecosystems in the Central Arctic Ocean (CAO). The CAO comprises the deep basins of the Arctic Ocean beyond the shelf break, which largely overlap with the High Seas of the Arctic Ocean, i.e. the marine areas outside the Exclusive Economic Zones (EEZs) of the Arctic coastal nations. The...

Corridors of Clarity: Four Principles to Overcome Uncertainty Paralysis in the Anthropocene

Polasky S., A.-S. Crépin, R. Biggs, S. R. Carpenter, C. Folke, G. Peterson, M. Scheffer, S. Barrett, G. Daily, P. Ehrlich, R. B. Howarth, T. Hughes, S. A. Levin, J. F. Shogren, M. Troell, B. Walker, and A. Xepapadeas. 2020. Corridors of Clarity: Four Principles to Overcome Uncertainty Paralysis in the Anthropocene. BioScience biaa115.

Global environmental change challenges humanity because of its broad scale, long-lasting, and potentially irreversible consequences. Key to an effective response is to use an appropriate scientific lens to peer through the mist of uncertainty that threatens timely and appropriate decisions surrounding these complex issues. Identifying such corridors of clarity could help understanding critical phenomena or causal pathways sufficiently well to justify taking policy action. To...

Urbanization, Migration, and Adaptation to Climate Change

Adger, W. N., A.-S. Crépin, C. Folke, D. Ospina, F. S. Chapin III, K. Segerson, K. C. Seto, J. M. Anderies, S. Barrett, E. M. Bennett, G. Daily, T. Elmqvist, J. Fischer, N. Kautsky, S. A. Levin, J. F. Shogren, J. van den Bergh, B. Walker, and J. Wilen. 2020. Urbanization, Migration, and Adaptation to Climate Change. One Earth 3(4): 396-399.

Climate change is reshaping the comparative advantage of regions and hence driving migration flows, principally toward urban areas. Migration has multiple benefits and costs in both origin and destination regions. Coordinated policies that recognize how and why people move can reduce future costs and facilitate adaptation to climate change both within borders and internationally.

Inertia Risk: Improving Economic Models of Catastrophes

Crépin, A.-S., and E. Nævdal. 2020. Inertia Risk: Improving Economic Models of Catastrophes. Scandinavian Journal of Economics 122(4):1259–1285.

We model endogenous catastrophic risk in a new way we term inertia risk, which accounts for delays between physical variables and the hazard rate—a characteristic often observed in reality. The added realism significantly impacts optimal policies relative to the standard model of catastrophic risk. The probability of a catastrophe occurring at some point in time may span the entire interval [0, 1] and is not...

Time-consistent resource management with regime shifts

Arvaniti, M., A.-S. Crépin, and C. K. Krishnamurthy. 2019. Time-consistent resource management with regime shifts. CER-ETH Economics working paper series 19/329 Center of Economic Research, ETH Zurich, Switzerland.

We investigate how a resource user who is present-biased manages a renewable resource stock with variable growth that could undergo a reversible regime shift (an abrupt, persistent change in structure and function of the ecosystem supplying the resource). In a discrete-time quasihyperbolic discounting framework with no commitment device, and using only generic utility functions and stock transition with regime shifts, we show that there is...

Migrant remittances can reduce the potential of local forest transitions – a social-ecological regime shift analysis

Ospina, D., G. Peterson, and A-S. Crépin. 2019. Migrant remittances can reduce the potential of local forest transitions - a social-ecological regime shift analysis. Environmental Research Letters 14(2):1–15.

We explore how remittances shape the effect of rural out-migration on the potential for local forest transitions. Building on an existing theoretical model of social-ecological regime shifts that links migration, farmland abandonment, and forest regrowth, we incorporate migrant remittances as an additional rural-urban teleconnection. We also extend the ecological dynamics to include a dynamical forest regrowth rate, generating a slowing-down of regrowth once the landscape...
