Ground Up Rethink of Disaster Relief
Disaster
relief has not kept up with the volume of mega natural calamities, a four-fold
increase since 1970. We can do the Trump blame game and deny or diminish relief
– coincidentally worse in blue states and territories than red – we can let
people waddle in rebuilding hell, often exacerbating economic realities and
national policies or keep pouring billions and billions of dollars in reactive
relief. You’d think we could plan against such horribles better, but kicking
the can down the road is a new American tradition. That we seem always to
choose the most expensive alternatives, that fixing or responding without a
precise plan is always more expensive than preventing or being truly ready for
what is inevitable.
Look
at Japan this past year, particularly devastated by natural disasters. “The
economy Japan's economy shrank in the
third quarter as natural disasters hit spending and disrupted exports… contracted
by an annualised 1.2% between July and September, preliminary figures showed… A
devastating earthquake and typhoon were among the disasters to hit Japan this
year, and prompted the bigger than expected [GDP] contraction.” BBC.com,
November 14th.
According to its corporate website, One Concern (a
new company applying artificial intelligence analytics to help government
disaster relief efforts), over the last 40 years, 3.3 million people have died
in natural disasters, which have inflicted $2.3 trillion in economic damage. As
populations increasing will live in cities – One Concern estimates that 60% of
the earth’s population will live in cities by 2030 – a natural disaster will
have a much greater potential for death and damage with such a concentration of
people.
The United States continues to lumber under the
vestiges of red state climate change denial. We see a reluctance from
developing nations to embrace severe limitations on greenhouse gas emissions
and countries like ours that place business earnings over human safety concerns.
But we are spending and will spend so much more than any aggregation of
business advantages by not grappling with climate change variables and not
redesigning our disaster relief efforts to reflect modern capacities and
realities.
As the United States deals with retrofitting its
energy generation and consumption policies, which it will sooner or later, it
also needs to revisit how governments analyze and deploy once a natural
disaster hits. That’s where artificial intelligence can benefit us all,
increasing effectiveness and implementing cost efficiencies.
“One Concern is launching a
machine learning platform that provides cities with specialized maps to help
emergency crews decide where to focus their efforts in a flood. The maps update
in real-time based on data about where water is flowing to estimate where
people need help the most. It’s the latest in a wave of AI-powered tools aimed at
helping cities prepare for an era of severe, and increasingly frequent,
disasters.
“Since
1980, the U.S. has suffered from 219 climate disasters that cost over $1 billion,
with the total cost exceeding $1.5 trillion. In 2017 alone, these
disasters cost the country $306 billion.
Since 2000, more than 1 million people have perished from
these extreme weather events. As climate change heralds more devastating
natural disasters, cities will need to rethink how they plan for and respond to
disasters. Artificial intelligence, such as the platform One Concern has
developed, offers a tantalizing solution. But it’s new and largely untested.
And the urgency is growing by the day.” FastCompany.com, November 15th.
One
Concern is the brainchild of Stanford University student Ahmad Wani, a native
Kashmiri who watched helplessly in his native country as floodwaters decimated
everything around him. He vowed to address the misfeasance in disaster relief.
Even in modern countries, disaster relief agencies deal with static maps and
old-world analytical tools that cannot process the complexity of
vulnerabilities, temperatures, weather patterns, population concentrations,
wind history, likely structural failures, access risks and availabilities,
water availability and the inevitable changes during a disaster that simple
were not anticipated. Simply, we are living in relatively unsophisticated dark
ages when it comes to real time disaster analytics.
“After
surviving the devastating flood in Kashmir, Wani returned to Stanford, where he
was studying structural engineering. He began contemplating how to predict a
disaster’s damage. The idea was that if city officials could anticipate which
areas would be most harmed, they would be able to deploy resources faster and
more efficiently throughout the disaster zone. But he had a problem: analyzing
a single building using traditional structural engineering software took seven
days on Stanford’s supercomputer. ‘We had to recreate that for the entire city’
for the idea to work, Wani says. ‘We didn’t have seven days or seven years. We
wanted to do it in three to five minutes.’
“He
decided to focus first on earthquakes, which are more of a threat than floods
in California. Wani teamed up with fellow Stanford students Nicole Hu, a
computer scientist who focuses on machine learning, and Tim Frank, an
earthquake engineer, to build an algorithm that can digest data about how a
building was built and how it’s been retrofitted over time. This data is
combined with information on the building’s materials and surrounding soil
properties to extrapolate what happens to this system when shaking occurs.
Then, when a quake hits, the model absorbs new information coming from
on-the-ground emergency responders, 911 calls, or even Twitter to make its
predictions of the damage more accurate.
“Because
the model identifies patterns by looking through large amounts of data, it
needs less computing power than the previous method of asking a computer to
perform complex physics equations to understand how shaking will impact a
structure. The trade-off is accuracy: Hu estimates that the algorithm is only
about 85% accurate. With more data over time, that number will improve, but the
team believes that it’s good enough to paint a broad picture of damage
immediately after a quake. (Of course, they won’t know for sure until a major
earthquake hits.)
“Wani,
Hu, and Frank started One Concern in 2015 and then released its
earthquake platform, called Seismic Concern, in 2016. Seismic Concern predicts
the damage caused by earthquakes on a block-by-block level and is now used by
eight different municipalities, including the cities of San Francisco, Los
Angeles, and Cupertino.
“Now,
the company is launching Flood Concern, a constantly evolving risk map that
crunches huge amounts of data based on the physics of how water flows,
information about previous floods, and even satellite imagery to approximate
the depth, direction, and speed of the water–and determine which areas of a
city are most at risk. Layered on top of the damage prediction is demographic
data, so that emergency planners can see what areas of a city might have
particularly vulnerable populations, like a significant percentage of seniors
or disabled citizens. With that kind of information, planners can figure out
which areas should be evacuated, where to put shelters, and what critical
infrastructure–like schools or hospitals–needs the most help when flooding
begins.” FastCompany.com
There
is a double message in this story. One deals with the use of modern tools to
address the rise in natural disasters. The other deals with an immigrant, one
of the best and the brightest, that Donald Trump wants to prevent from entering
the United States, a person of color with a different religious background who
is a “them” and not “us.” You tell me who the biggest loser is under than
less-than-subtle Trump nationalist policy.
I’m Peter Dekom, and never before has
the world required more international cooperation, more group think, to solve
complex problems… and the United States needs to remember that it became great
because it was a nation of immigrants!
