Staff profile

Anne-Sophie Crépin is an environmental and resource economist focusing on resources and services that stem from ecosystems

Profile summary

  • A substantial part of her work is based on small theoretical dynamic
    models that combine relevant economic factors with complex ecosystem
  • She teaches within the module Challenges of Environmental
    Decision-making within the Stockholm Resilience Centre’s Master’s
  • She is the deputy director of the Beijer Institute of Ecological Economics

Anne-Sophie Crépin has a background in environmental and resource economics and focuses on issues related to sustainability and resilience.

Her research links scientific theories about the Anthropocene, regime shifts and economic dynamics and aims to answer mainly two broad questions:
1.    In what way does the interplay between ecosystems and socioeconomic dynamics influence the risk of abrupt changes which could lower human well-being?
2.    How can society deal with this risk in a way that sustains long term human well-being?

A substantial part of her work is based on small theoretical dynamic models that combine relevant economic factors with complex ecosystem dynamics. Recent publications also include more empirical studies and behavioural experiments.

Her work addresses management of resources with potential regime shifts like grasslands, coral reefs, forests, etc. She has studied models with common property management, fast and slow dynamics, uncertainty, diversity and policy interventions. Her recent work deals with the representation of larger and complex social ecological systems with cross scale interactions like the Arctic Ocean.

Anne-Sophie Crépin teaches within the module Challenges of Environmental Decision-making within the Stockholm Resilience Centre’s Master’s Programme Social-Ecological Resilience for Sustainable Development.

She is the deputy director of the Beijer Institute of Ecological Economics, where she has har main affiliation. She was a council member for the European Association of Environmental and Resource Economics. She participated in the Millennium Ecosystem Assessment.

Collective action and the risk of ecosystem regime shifts: Insights from a laboratory experiment

Schill, C., T. Lindahl, A.-S. Crépin

2015 - Journal / article

Ecosystems can undergo regime shifts that potentially lead to a substantial decrease in the availability of provisioning ecosystem services. Recent research suggests that the frequency and intensity of regime shifts increase with growing anthropogenic pressure, so understanding the underlying social-ecological dynamics is crucial, particularly in contexts where livelihoods depend heavily on local ecosystem services. In such settings, ecosystem services are often derived from common-pool resources. The limited capacity to predict regime shifts is a major challenge for common-pool resource management, as well as for systematic empirical analysis of individual and group behavior, because of the need for extensive preshift and postshift data. Unsurprisingly, current knowledge is mostly based on theoretical models. We examine behavioral group responses to a latent endogenously driven regime shift in a laboratory experiment. If the group exploited the common-pool resource beyond a certain threshold level, its renewal rate dropped drastically. To determine how the risk of such a latent shift affects resource management and collective action, we compared four experimental treatments in which groups were faced with a latent shift with different probability levels (0.1, 0.5, 0.9, 1.0). Our results suggest that different probability levels do not make people more or less likely to exploit the resource beyond its critical potential threshold. However, when the likelihood of the latent shift is certain or high, people appear more prone to agree initially on a common exploitation strategy, which in turn is a predictor for averting the latent shift. Moreover, risk appears to have a positive effect on collective action, but the magnitude of this effect is influenced by how risk and probabilities are communicated and perceived.

Does Aquaculture Add Resilience to the Global Food System?

2014 - Journal / article

Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. However, aquaculture's reliance on terrestrial crops and wild fish for feeds, its dependence on freshwater and land for culture sites, and its broad array of environmental impacts diminishes its ability to add resilience. Feeds for livestock and farmed fish that are fed rely largely on the same crops, although the fraction destined for aquaculture is presently small (∼4%). As demand for high-value fed aquaculture products grows, competition for these crops will also rise, as will the demand for wild fish as feed inputs. Many of these crops and forage fish are also consumed directly by humans and provide essential nutrition for low-income households. Their rising use in aquafeeds has the potential to increase price levels and volatility, worsening food insecurity among the most vulnerable populations. Although the diversification of global food production systems that includes aquaculture offers promise for enhanced resilience, such promise will not be realized if government policies fail to provide adequate incentives for resource efficiency, equity, and environmental protection.
