Tsunami
towns urged to plan reconstruction
Communities
given helping hand with responsible
rebuilding

The
villagers of Kirinda in southeast Sri
Lanka lost almost everything in the Indian
Ocean tsunami. Now, a group of architects
hopes to make this tiny fishing community
a model for reconstruction efforts in the
regions affected by the disaster.
The
biggest fear, says Cameron Sinclair of the
New York-based Architecture for Humanity,
is that unscrupulous builders will throw
up unplanned structures in dangerous
locations.
"Once the
relief and recovery are done, people will
start building," Sinclair says. "The
worst-case scenario is concrete blocks
appearing everywhere."
Architecture for Humanity has sent a team
of planners, architects, biologists and
environmentalists to Kirinda in the hope
of helping villagers to rebuild their
community in a safe and sustainable way.
"The
community will be a 50% player in this,"
Sinclair stresses. "But when push comes to
shove, we will be making the tough
decisions." The team plans to work in
Kirinda throughout 2005, and hopes to
begin extensive building work this summer.
Talking
tough
The Sri
Lankan government recommends that coastal
villages re-establish themselves further
from the shore. But this isn't what the
locals want, so the architects are likely
to go along with the villagers' views in
this case, says Sinclair.
"Communities won't be moving an inch," he
says. "People even want to pitch their
tents where their home was."
However,
they will fight against the cobbling
together of shoreline shacks by fishermen.
Sinclair points out that neighbouring
villages that had sand dunes, rather than
sea-front buildings, suffered far less at
the hands of the deadly wave on 26
December.
The
architects are also keen to preserve
Kirinda's environmental resources,
including the bird sanctuary and national
parkland that flank the village. They plan
to ensure that the construction effort
uses local resources, employing local
workers and building with wood and earth,
rather than concrete.
Improved resilience
It is
often local economics rather than local
planning that dictates how towns grow in
the developing world, says Zygi Lubkowski,
a London-based engineer with Arup and
chairman of the Society for Earthquake and
Civil Engineering Dynamics.
Fishing
villages owe their livelihood to the sea,
so communities will end up colonizing the
sea front, he points out.
But if
people do not want to move, he warns that
they will need to make themselves more
resilient in the face of future tsunamis.
One way to
do this is to ensure that key
infrastructure elements such as hospitals
and police stations are located in
protected spots, Lubkowski says. "So when,
god forbid, it happens again, help is
there when it's needed."
Those
overseeing construction efforts also need
to be aware of how their actions might
precipitate other disasters, such as
landslides, Lubkowski says. "The easiest
way [to avoid tsunamis] is to keep
buildings at a higher elevation, but you
need to check the slopes are stable,
especially when vegetation is removed."
Hong Kong
island, for example, has been destabilized
by heavy construction, he says.
For poor
communities in the regions affected by the
Indian Ocean tsunami, awareness may be the
best defence, Lubkowski concludes.
Learning the warning signs, and having a
well-rehearsed escape plan, could save
countless lives next time around.
