Response diversity as a sustainability strategy. Nature Sustainability 6:621-629.

Financial advisers recommend a diverse portfolio to respond to market fluctuations across sectors. Similarly, nature has evolved a diverse portfolio of species to maintain ecosystem function amid environmental fluctuations. In urban planning, public health, transport and communications, food production, and other domains, however, this feature often seems ignored. As we enter an era of unprecedented turbulence at the planetary level, we argue that ample responses...

Perspectives on aquaculture’s contribution to the Sustainable Development Goals for improved human and planetary health

Troell, M., B. Costa-Pierce, C. Stead, R.S. Cottrell, C. Brugere, A.K. Farmery, D. Little, Å. Strand, R. Pullin, D. Soto, M. Beveridge, K. Salie, J. Dresdner, P. Moraes-Valenti, J. Blanchard, P. James, R. Yossa, E. Allison, C. Devaney, and U. Barg. 2023. Perspectives on aquaculture's contribution to the Sustainable Development Goals for improved human and planetary health. Journal of the World Aquaculture Society 54(2):251-342.

The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in the future. Its important role for food security, nutrition, livelihoods, economies, and cultures is not clearly visible in the Agenda 21 declaration. This may partly reflect the state of development of policies for aquaculture compared with its terrestrial counterpart, agriculture, and possibly also because...

Sustaining local commons in the face of uncertain ecological thresholds: Evidence from a framed field experiment with Colombian small-scale fishers

Schill, C. and J.C. Rocha. 2023. Sustaining local commons in the face of uncertain ecological thresholds: Evidence from a framed field experiment with Colombian small-scale fishers. Ecological Economics 207:107695.

Due to climate change abrupt and persistent changes in ecosystems, impacting millions of livelihoods, are likely but hard to predict. How people respond to such uncertain ‘regime shifts’ is poorly understood. Here, we assess the potential for local collective action to avert uncertain, yet catastrophic, regime shifts using behavioural economic experiments with 256 small-scale fishers from the Colombian Caribbean coast. With a framed, dynamic common-pool...

Reshaping a resilient future in response to COVID-19

Rockström, J., A.V. Norström, N. Matthews, R. Biggs, C. Folke, A. Harikishun, S. Huq, N. Krishnan, L. Warszawski, and D. Nel. 2023. Reshaping a resilient future in response to COVID-19. Nature Sustainability 1-11.

Science today defines resilience as the capacity to live and develop with change and uncertainty, which is well beyond just the ability to ‘bounce back’ to the status quo. It involves the capacity to absorb shocks, avoid tipping points, navigate surprise and keep options alive, and the ability to innovate and transform in the face of crises and traps. Five attributes underlie this capacity: diversity,...

Sanctioned quotas versus information provisioning for community wildlife conservation in Zimbabwe: A framed field experiment approach

Ntuli, H., A.S. Crépin, C. Schill, and E. Muchapondwa. 2023. Sanctioned quotas versus information provisioning for community wildlife conservation in Zimbabwe: A framed field experiment approach. Environmental and Resource Economics 84(3):775-823.

We investigate the behavioural responses of natural common-pool resource users to three policy interventions—sanctioned quotas, information provisioning, and a combination of both. We focus on situations in which users find utility in multiple resources (pastures and wild animal stocks) that all stem from the same ecosystem with complex dynamics, and management could trigger a regime shift, drastically altering resource regrowth. We performed a framed field...

Approximately optimal forest rotation in a nonstationary environment

Gars, J. and D. Spiro. 2023. Approximately optimal forest rotation in a nonstationary environment. Natural Resource Modeling e12372.

The problem of optimal forest rotation in a nonstationary environment can, in general, not be solved analytically. Even qualitatively characterizing how the solution changes over time is only possible in some special cases. In this paper, we consider an approximation of the true solution to the nonstationary problem. We derive an approximate harvesting rule by solving a sequence of stationary problems that assume the growth...

Insurance value of biodiversity in the Anthropocene is the resilience value?

Hahn, T. et al. 2023. Insurance value of biodiversity in the Anthropocene is the resilience value?. Ecological Economics 208:107799.

Recently two distinctly different conceptualisations of insurance value of biodiversity/ ecosystems have been developed. The ecosystem framing addresses the full resilience value without singling out subjective risk preferences. Conversely, the economic framing focuses exactly on this subjective value of risk aversion, implying that the insurance value is zero for risk neutral persons. Here we analyse the differences conceptually and empirically, and relate this to the...
