The Evolution of Integrated Assessment: Developing the Next Generation of Use-Inspired Integrated Assessment Tools
Posted: 26 Oct 2020

In this review, we attempt to describe the evolution of integrated assessment modeling research since the pioneering work of William Nordhaus in 1994, highlighting a number of challenges and suggestions for moving the field forward. The field has evolved from global aggregate models focused on cost-benefit analysis to detailed process models used to generate emissions scenarios and to coupled model frameworks for impact analyses. The increased demand for higher sectoral, temporal, and spatial resolution to conduct impact analyses has led to a number of challenges both computationally and conceptually. Overcoming these challenges and moving the field forward will require not only greater efforts in model coupling software and translational tools, the incorporation of empirical findings into integrated assessment models, and intermethod comparisons but also the expansion and better coordination of multidisciplinary researchers in this field through better training of the next generation of integrated assessment scholars and expanding the community of practice.
