Multisector Dynamics: Advancing the Science of Complex Adaptive Human‐Earth Systems

“…There are however methodological, data availability, and computational gaps that are at present limiting the MSD community's ability to confront the complexity of human‐Earth systems and their feedbacks. There is a need for: (a) better integration with complexity science (Haimes, 2018; Meerow & Newell, 2015; Montuori, 2013), (b) improved modes of analysis for capturing uncertainties in how human systems shape dynamics (Axelrod, 2006; Filatova et al., 2016; Moallemi & de Haan, 2019; Polhill et al., 2016; Trutnevyte et al., 2019; Zellner, 2008), (c) computational advances that enhance representations of highly nonlinear and uncertain “state‐action” feedbacks (Bertsekas, 2019; Herman et al., 2020; Oikonomou et al., 2021; Powell, 2019), and (d) solutions to overcome computational scaling and scientific inference barriers to MSD research insights (Bergman et al., 2019; Hendrickson, 2020; McGovern & Allen, 2021; National Academies of Sciences & Medicine, 2016). Addressing these gaps will require deeper collaborations with the statistical, mathematical, and computational sciences.…”
