Citizen support for policy interventions implemented to achieve more sustainable food consumption: The role of policy design and presentation
Lindahl. T. 2026. Citizen support for policy interventions implemented to achieve more sustainable food consumption: The role of policy design and presentation. Current Research in Environmental Sustainability 11:100346.
This study examines public support for policy packages comprising taxes, subsidies, or both designed to reduce the consumption of animal-based protein (e.g., beef, pork, chicken and cheese). Specifically, we investigate whether support varies depending on how these policy packages are designed and presented. While previous research shows that the design of carbon taxes can influence public acceptance, there is limited evidence on whether similar results...
Both adaptive and transformative capacities are necessary to navigate global polycrisis
Søgaard Jørgensen, P., L. Delannoy, S. Maniatakou, C. Folke, M.-L. Moore, and P. Olsson. 2026. Both adaptive and transformative capacities are necessary to navigate global polycrisis. Global Sustainability 9(e16):1–9.
Efforts toward global sustainability transformations risks being undermined by the formation of a global polycrisis, where multiple global challenges such as climate change, biodiversity loss, geopolitical conflict, and pandemics interact to reinforce each other. Resilience scholarship has identified multiple capacities needed for adaptation and transformation of social-ecological systems. Here, we explore the leverage and vulnerability of such capacities to the global polycrisis. We find that...
A politically determined carbon tax with targeted public good investments and individual voter investments to change their fossil-fuel reliance
Gars, J., G. Engström, and T. Lindahl. 2026. Beijer Discussion Paper 286: A politically determined carbon tax with targeted public good investments and individual voter investments to change their fossil-fuel reliance. Beijer Discussion Paper Series.
In this paper we set up a model to consider how individual voter characteristics determine their policy preferences over the level of a tax on fossil energy. We introduce the possibility for voters to invest to change their reliance on fossil versus clean energy. The effect of this on preferred tax rates are, in general, ambiguous. If a tax would be high enough to make...
Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability
Nicholas, K. M., A. Tone , T. Beal, J. Zamborain-Mason, H. Eneroth, V. Öhrvik , M. Troell, and C. D. Golden. 2026. Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability. The American Journal of Clinical Nutrition 123(5).
Increasing attention has focused on the capacity of current global food systems to provide accessible, affordable, and sustainable food to a growing human population, particularly amid ongoing climate and environmental changes. Concerns about the dysfunction of the global food system have led to the development of several initiatives to estimate current and predict future global nutrient supplies based on various climate, production, and demand scenarios....
Global nutritional equity of fishmeal and aquaculture trade flows
Elsler, L. G., J. A. Gephart, J. Zamborain-Mason, T. Cashion, M. Troell, R. L. Naylor, R. Agrawal Bejarano, and C. D. Golden. 2026. Global nutritional equity of fishmeal and aquaculture trade flows. PNAS 123(7).
Aquaculture, the single fastest growing food sector, is central to achieving key SustainableDevelopment Goals (e.g., SDG 2: Zero Hunger). Linking the nutrient compositionof >2,800 aquatic species with >2 million fishmeal and farmed fish transactions ininternational aquatic food trade between 2015 and 2019, we examined aquaculture’snutritional flows and distributional equity. We found that aquaculture provided adequateintakes for nearly a quarter of a million individuals, on average,...
Bridges
Tompsett, A.. 2026. Bridges. Review of Economic Studies https://doi.org/10.1093/restud/rdaf104.
Bridges are critical but sparse links in land transport networks. I exploit quasi-experimental variation in bridge construction over major rivers in the U.S. to measure the causal effects of land transport infrastructure. Bridges are more often built upstream than downstream of tributary confluences—where smaller rivers join larger rivers—generating local differences in connectivity. Local connectivity advantages have negative effects on per capita income. In contrast, more...
What is the evidence on indirect drivers of biodiversity loss worldwide? A systematic map protocol
Grossi, F., D. I. Avila-Ortega, A.-S. Crépin, E. A. Virtanen, E. Di Minin. 2026. What is the evidence on indirect drivers of biodiversity loss worldwide? A systematic map protocol. PLOS One 21(3): e0341928.
An estimated 1 million species of animals and plants are threatened with extinction. While much research has concentrated on direct drivers (e.g., land use change) of biodiversity loss, understanding the indirect (e.g., economic, demographic, and institutional, etc.) drivers triggering these direct drivers is a research priority. Systematic reviews of literature mapping the links between indirect and direct drivers and where, when, how, and what biodiversity...
Efficient and sustainable management of shared fisheries in Thailand: Self-governance or regulation?
Jarungrattanapong, R. and T. Lindahl. 2026. Efficient and sustainable management of shared fisheries in Thailand: Self-governance or regulation?. Ecological Economics 246(109019).
Artisanal fisheries are significant for poverty alleviation, but they are severely threatened by overfishing and climate change effects. Governance solutions can be hard to find when their implementation and success depend on both social and ecological contexts. In this study, we aim to increase our understanding of behavioral strategies adopted by artisanal fisheries under different types of governance scenarios using a field experiment in the...
A robot-assisted pipeline to rapidly scan 1.7 million historical aerial photographs
Masson, S., A. Potts, A. Williams, S. Berggreen, K. McLaren, S. Martin, E. Noda, N. Nordfors, N. Ruecroft, H. Druckenmiller, S. Hsiang, A. Madestam, and A. Tompsett. 2026. A robot-assisted pipeline to rapidly scan 1.7 million historical aerial photographs. npj Heritage Science 14(123).
During the 20th Century, aerial surveys captured hundreds of millions of high-resolution photographs of the Earth’s surface. These images, the precursors to modern satellite imagery, represent an extraordinary visual record of the environmental and social upheavals of the 20th Century. However, most of these images currently languish in physical archives where retrieval is difficult and costly. Digitization could revolutionize access, but manual scanning is slow...
Speech-based measurement of polarization using text-as-data
Engström, G., S. Axelsson, J. Gars, S. Källman, and T. Lindahl. 2026. Beijer Discussion Paper 285: Speech-based measurement of polarization using text-as-data. Beijer Discussion Paper Series.
Political polarization research depends on valid measurement of policy positions, yet established data sources—roll-call votes, elite surveys, ex- pert judgments—are limited in temporal coverage and substantive scope. Parliamentary speech offers an alternative: abundant, publicly available text that reflects real-time political positioning across all policy debates. However, whether speech-based measures recover the same latent con- structs as survey instruments remains an open empirical question, partic- ularly...
