Building robust communities: embracing complexity and diversity?

Robustness is the ability, for a community, to withstand or overcome adverse conditions. Whereas what defines and makes communities robust is studied in different disciplines, there are few interdisciplinary approaches aiming at comparing how, across scales, similarities in building robust communities exist. Here, we propose to form a team to identify whether there are commonalities and differences in the way communities as seen by a biologist (molecules, cells, organisms), an ethnologist (structured social groups, cities) and an economist (rational economic actors) achieve a robust organization to ensure their cohesion and function in face of disruptive events. Our work will focus on the advantages/disadvantages of diversity and complex connectivity for the emergence of a robust community. We will examine these concepts in state-of-the-art work within our selected fields, consider the limits and potential of these concepts and compare them across disciplines. While this project has connections to the flagship initiative Transforming Cultural Heritage, it also links, albeit secondarily, to the Engineering Molecular System one.
