Social Tectonics and the Trust of Cities
The strength of a country, and especially the strength of a city, is its ability to react to, and repair, the social fissures that originate wherever three or more humans live together. Social tectonics is the natural fracturing along societal lines like wealth, education, ethnicity, religion, sexual orientation, even color of skin, shapes of noses, or sports team preferences. Humans are amazingly adept at finding things in others to be wary of.
Social tectonics is active everywhere. No government or leader can stop it – but much can be done to reinforce our societies, institutions and cities, as well as reducing stresses. Like observant seismologists, social scientists sense where stresses are increasing and approaching breaking points. For example, the Occupy Movement that has popped up in many American cities represents growing stress in people who see too much concentration of wealth. The Arab Spring is a fracture between the general populace and the few who concentrated political power.



Sustainable development always seems to come in shades of grey; excuses, obfuscation, conflicting demands, entrenched interests, and inertia can overshadow clarity on what needs to be done ‘on Monday morning’. But for some reason, like Rio de Janeiro’s iconic black slate and white marble sidewalks, sustainable development seemed to be a lot more black and white at last week’s big 
Cities are often violent places – a social, ethnic and religious tinderbox of people piled up together with competing needs for space, housing or cash. Mostly the tension is contained, but not always - when and why does it spill over into bloody mayhem? That’s the question at the heart of a fascinating research project run by

After months of expectation and years of very hard (and in some cases, not hard enough) work towards the goal of sustainable development, heads of state and environmentalists alike are gathering at Rio+20 to determine what we’ve accomplished in the last two decades and how we’re going to pave the road that lies ahead.
