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, simi-larities 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 organisation to ensure their cohesion and function in face of disruptive events. Our work will focus on the ad-vantages/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 se-lected fields, consider the limits and potential of these concepts and compare them across disciplines. While this project has connections to the flashship initiative Transfor-ming Cultural Heritage, it also links, albeit secondarily, to the Engineering Molecular Sys-tem one.
