Adaptation and
Resilience Planning at
Dar Al-Handasah
The World Bank recently published a report stating that 1.3 billion people and 158 trillion
U.S. dollars' worth of assets will be vulnerable to climate change by 2050. The report
concluded that
hazard was increasing due to climate change, exposure was going up
because more people were living in hazardous areas, and
vulnerability was on the rise
because of badly designed and poorly planned housing.
These days there are many international agencies helping to respond to immediate
crises. These interventions have traditionally focused on relief and rebuilding, or on
longer-term development, rather than planning for unforeseen shocks and stresses. The
Rockefeller foundation estimates that as a result,
$1 of every $3 spent in development
assistance is wasted.
Even in rich established cities such as London and New York, the risks are very real and
the consequences very costly. New York City quickly found this out in 2009 when a storm
surge flooded Manhattan Island for the first time in its history after Hurricane Sandy. Vital
services, including backup generators, were crippled as water flooded the mandatory
basement plant rooms of the famous skyscrapers and the underground train system
that connects them. Mayor Bloomberg announced that the storm had caused $19 billion
in losses in New York City. Additionally, the storm required prevention and mitigation
strategies estimated at more than $9 billion dollars, work which is still continuing.
Through its London Sustainability Group, Dar is making a concerted effort
towards adaptation and resilience, both internally and with clients.

Adaptation Key Terms and Definitions
·
Mitigation: Technological change and substitutions that reduce
resource inputs and emissions per unit of output. Although
several social, economic and technological actions would
reduce emissions, with respect to climate change, mitigation
means implementing actions to reduce greenhouse gas
emissions or increase the amount of carbon dioxide absorbed
and stored by natural and man-made carbon sinks.
·
Resilience: A capability to anticipate, prepare for, respond
to, and recover from significant multi-hazard threats with
minimum damage to social well-being, the economy and the
environment.
·
Adaptive Capacity: The potential of a system to adjust to
climate change (including climate variability and extremes) to
moderate potential damages, take advantage of opportunities
and cope with the consequences.
·
Adapt, Adaptation: Adjustment in natural or human systems
to a new or changing environment that exploits beneficial
opportunities or moderates negative effects.
