E. Galbraith (seminar) - Integrating coupled human activity in Earth System models

Humans have become the major driver of change within the climate, marine ecosystem, and terrestrial ecosystem of our planet. Yet, most conceptual and scientific frameworks treat human activity as an external driver of change, rather than a coupled component of a unified system. I will discuss two examples of ongoing efforts to build coupled human-Earth models. The first is a model of the global wild capture fishery, directly coupled to an ocean biogeochemical model at the grid scale, which I use for conducting centennial-timescale simulations under changing climatic and socio-economic boundary conditions. The second example is a generalized model of human activity, suitable for integration with grid-based terrestrial ecosystem models. Although both models are still in the early stages of development, I will provide suggestions for how they might evolve, and how they could provide useful insights with policy relevance. 


Eric Galbraith is an ICREA Research Professor, based at the Universitat Autònoma de Barcelona. He has previously worked as a research associate at Princeton University in the US, and a professor at McGill University in Canada. His research is broadly interdisciplinary, and is generally concerned with using numerical models and data analysis to better understand the interactions between climate change, human activities and ecosystems. He has worked on both past and anticipated climate changes and their links with ocean biogeochemistry, as well general principles of nutrient cycling, ecosystem stoichiometry and macroecology. His current research focuses on methods for including human activity as an integral part of Earth system models.
