The City as an Ecosystem: The GRID works like a wonder. But be ready when it falls apart
A city is an urban ecosystem which include both nature and humans. It
is a human created environment with different functional parts that keep
its residents alive and well. The creation of food surpluses helped
promote development of extended urban ecosystems--a small town evolves
with more areas assigned for living, for working, for learning, for
entertainment, for power and utilities, and for getting supplies.
Keeping an emergency food supply for extreme situations is a no-brainer to survive
lesson that we must understand about modern urban ecosystems is that
its lifeline is dependent on a grid where material and energy flowpaths
into and out of cities travel in a linear fashion that is always prone
to interruptions, and in the worst case scenario, a complete shutdown.
a city ecosystem were cyclic and built to organically replenish itself
whether via redundancy and support systems and caches of emergency
supplies, then we wouldn't be worrying about the next Ondoy or Yolanda.
of the biggest factors why America became The New World for immigrants
seeking a better life was that the entire continent was a frontier for
development while in Europe, the cites became areas for stagnation and
corruption which choked opportunities for the growing populace. The
American Dream when that great nation was coming together was having
one's own homestead for anyone willing to till the land.
this age of megacities, the cycle repeats itself as some areas flounder
due to economic collapse and fiscal corruption and the few that remain
resilient and still keep well are the urban ecosystems with dedicated
support systems and redundancy as well as good governance and access to
food belts and waterways (mostly seaside cities like Boston and Canadian
If the ecosystem grid of any single city collapsed, you can imagine how crazy it would be if it cannot be restored immediately. Even a week's loss of the grid's function can create turmoil, just remember Hurricane Katrina hitting New Orleansway back when and that mess showed that even a first world nation had it up to its neck trying to restore the grid of an urban ecosystem.
What can we do to stay resilient?
Urban ecosystems are complex interdependent systems. Urban planners need to carefully design the elements of the ecosystem to deal with seasonal water cycles and extremes such as floods and droughts, traffic flow that does not impair supply deliveries nor work productivity, communications survivability in any extreme situation, crime prevention and law enforcement, military defenses and civil defense plans for extreme situations, plans for health epidemics and keeping health services one of the most resilient and survivable parts of the ecosystem.
As an individual or as communities within the GRID, there are personal and group survival preparations that need to be ready yesterday, like having alternate power supply systems like solar PVs, keeping an emergency food supply stored per family, self defense equipment for when crime as a result of the grid collapsing escalates, and a means of escape such as vehicles for when the ecosystem cannot be restored and the city literally becomes a ruin of edifices and roads.
Be ready and be prepared for the worst case scenario in any extreme situation. Help each other as much as one can without losing one's dignity and chance of survival. And still watch your back at the same time.
