Economic growth futures, climate change, and society
GDP per capita is highly connected to many important measures of societal being, including poverty rates, greenhouse gas (GHG) emissions, and capacity for adaptation, to name three. The range of expert projections of world GDP per capita in 2100 spans nearly an order of magnitude, and authoritative forecasts have often over-projected growth and under-projected inequality in the past. With this much uncertainty, how can we adequately plan for future climate change and other societal challenges? We are working on developing new approaches to forecasting economic growth, improving projections of GHG emissions, and anticipating societal challenges that may arise under various future economic growth trajectories.

Mathematical modeling of human-environment systems
Effectively managing natural resources is essential to food security, livelihoods, and sustaining diverse and productive ecosystems. Yet resource management is caught between needs for complexity and simplicity. On the one hand, the complexity of coupled social-ecological systems pulls natural resource science towards complex models and data-hungry assessment approaches. The need for often large-scale cooperation to achieve management targets, which are as dynamic as the science, pulls resource management towards institutionally complex and (economically) expensive management. On the other hand, many systems lack the data, and financial and institutional capital to implement even the simplest existing approaches to natural resource science and management.
We are interested in developing pragmatic and interdisciplinary approaches to studying and managing natural resources, with explicit considerations of financial, scientific, and institutional constraints. Within this theme, some overarching questions are: (i) Can we find useful theoretical insights that are not data-dependent or system-specific? (ii) How strong are tradeoffs between different resource management objectives? (iii) Are there approaches to assessment or management that are relatively easy to implement and produce 'pretty good' outcomes (as Hilborn says) in many different social and ecological contexts? (iv) Are there existing but untapped data sources that might provide insightful information?

Fig. 2 from Hegwood et al. SocArXiv: cfp43 (2021): The figure (and paper) shows why tradeoffs become more severe--as measured by the maximum simultaneously achievable fraction of all single-objective maxima [X(n )]--as the number of objectives (n ) increases. We show that the limit of X(n ) as n approaches infinity does not depend on the tradeoff surface's curvature.
Reducing political polarization of environmental issues
In the U.S. and some other developed democracies, political polarization might be the single biggest obstacle to widespread and long-lasting action to address climate change. We are working to understand how we can move past this polarization, by examining past success in bipartisanship at the state level and trends in public opinion polls, and by convening dialogs among politically diverse community members.

Mechanistic approaches to conservation
Current approaches to assessing threats of collapse and extinction to species are predominantly phenomenological, inferring threats from past population declines, high current mortality rates, species rarity, or life history characteristics correlated with threat histories of other species. We develop mechanistic approaches to measuring conservation threats, which quantify combinations of biological and socioeconomic conditions that are likely to eventually cause high mortality rates and population declines. Mechanistic approaches have two key advantages. First, they can identify threats of future extinction and severe population decline before the declines occur. Second, mechanistic approaches can be used to quantify tradeoffs and synergies between conservation and other social and ecological objectives. We have found that the nature of these tradeoffs is sometimes counterintuitive.
