The Anthropocene challenge:
People are pushing the planet in one direction,
but want things to stay the same
The ‘Bretherton Diagram’ (NASA 1988) set out the observational, conceptual and
computational modelling framework for 1-2 decades of global change research.
How do we know? We simplify. We observe*.

Change. University Center, MI: The Consortium for International Earth Science Information Network (CIESIN).
What kind of complex system
is planet Earth?
(apart from large… many parts, of many different kinds, with multiple connections,
and that interact across all scales (von Bertalanffy 1968)
Living and non-living parts
of the planet interact.
They co-evolve.
Some living parts think,
and have foresight.
The Gaia Hypothesis –our planet functions as a
single organism that maintains the conditions necessary
for its survival.
James Lovelock
“hybrid” systems
• assemblages of inorganic, organic and social systems
(de Landa, Deleuze, Bhaskar)
Adaptive systems
• Resilience (and resiliencespeak)
� self-organizing, responsive, co-evolving
Purposive systems?
Learning systems?
(OR and management heuristics, classic systems methods,
Ackoff & Gharajedaghi 1996 – purpose in wholes/parts)
The Brundtland report:‘Sustainable development aims
to promote harmony among human beings
and between humanity and nature’.
And it specifies a multifaceted integration:
• a political system that secures effective citizen participation in decision making,
• an economic system that is able to generate surpluses and technical knowledge on a self-reliant and
sustained basis,
• a social system that provides for solutions for the tensions arising from disharmonious development,
• a production system that respects the obligation to preserve the ecological base for development,
• a technological system that can search continuously for new solutions,
• an international system that fosters sustainable patterns of trade and finance, and
• an administrative system that is flexible and has the capacity for self-correction.
World Commission on Environment and Development (1987) Our Common Future, A/42/427. Chapter 2 The concept of Sustainable Development. www.un-documents.net/ocf-02.htm.
1987: Harmony between humanity and nature, among human beings
1992: climate, ecosystems, human-changed landscapes (UNFCCC, CBD, UNCCD)
2000: 8 millennium goals – nb No. 8 (systemic change) has been ignored
2010: 20 biodiversity targets
2012: 9 then >12 sustainability goals proposed
2015: 17 goals, many targets, hundreds of indicators…
� Complicating the analysis sort of suggests (some) people don’t really want to change...
