Hartmut Bossel is a German systems scientist whose work on sustainability indicators intersected directly with Donella Meadows's research program during the balaton-and-sustainability-indicators-1982-2001 era. He is notable in Meadows's network primarily as a collaborator on the indicators problem — the question of how to measure whether a society is moving toward or away from sustainability.
Bossel developed the "system viability" approach to sustainability assessment, arguing that sustainable systems must satisfy a set of basic orientors — existence, effectiveness, freedom, security, adaptability, coexistence, and psychological needs. This framework for decomposing sustainability into testable dimensions had significant overlap with the approach Meadows pursued through the balaton-group and the sustainability-institute's indicators-of-sustainability-1998 work.
The balaton-group, which Meadows convened annually at Lake Balaton in Hungary, was the primary institutional context for Bossel's collaboration with Meadows. The group brought together systems thinkers, sustainability researchers, and modelers from multiple countries, and Bossel's participation made him part of the international network through which Meadows's sustainability indicators work was developed and refined.
Bossel's work on system dynamics and sustainability modeling also intersected with the broader mit-system-dynamics-group tradition, though he was not a Forrester student. His approach to modeling complex systems — emphasizing viability and adaptive capacity — connects to Meadows's emphasis on resilience and self-organization in thinking-in-systems-2008.
Within Meadows's network, Bossel occupies the position of a technically rigorous collaborator in the indicators and sustainability modeling domain, distinct from the co-author relationship she had with dennis-meadows and jorgen-randers on the Limits books, and distinct from the intellectual-ally relationship she had with herman-daly on the critique of growth economics. His collaboration represents the more specialist, technical dimension of the sustainability-institute research agenda.
