Understanding the new, highly connected nature of urban environments like Mumbai or Nairobi is an important first step in preparing to deal with this problem. Big data can sometimes help. Analysts can now track millions upon millions of data points (traffic patterns, say, or cellphone usage, or pedestrian movement, or prices in markets, or internet hits, or bank transactions, or numbers and types of cars in parking lots) to understand, through remote observation, how a city works.
But how do we do that in enormous megaslums that are constantly growing and morphing and which don't have the street names and building addresses that allow geo-data to mean something?
Many of today's coastal cities, especially those in the developing world, are growing at breakneck speed. In a conflict, people's uncertainty arises from armed groups targeting the population; in a city that's growing exponentially – constantly outgrowing itself – the same terrifying lack of predictability can arise simply from the pace of change. Thus a megacity under stress can offer opportunities for
conflict entrepreneurs (gang leaders, crime bosses or militant extremists) to control populations, provided they create a predictable rule set that makes people feel safe in the face of instability. This occurs because of the predictability inherent in the rules, whether people like the group or not, and regardless of the content of those rules. You don't have to like the cops, or agree with the speed limit, for the road rules to make you feel safe.
Eventually, provided the group builds consistency and order, through a spectrum of persuasive, administrative and coercive measures, it may gain the loyalty and support of the local population.

As we dust ourselves off after a decade of war, community resilience, public safety and economic opportunity in crowded urban areas may turn out to matter more than counterterrorism or counterinsurgency. Designers and urbanists speak of participative development and human-centred design as key elements of a new approach to city development.
Figuring how to co-design solutions in partnership with a local community, when the community is under threat and someone is shooting at you, may be the hardest challenge of all.
