Mitigation
Adaptation
Working to reduce
the severity of a
problem/issue.
Working to adjust
to an unavoidable
problem/issue.
Example: the aging movie star
From ages 20-35, the actress was offered many
leading movie roles.
She continued auditioning for these roles, but
starting around age 40, she noticed that she was
being offered fewer and fewer leading roles.
She is now 50 years old and has not been offered a
leading role in over 5 years. Her agent suspects that
she is not being offered these parts because she
looks older than the other younger actresses who
are auditioning.
• What could the actress do to attempt to
mitigate this situation?
• What could the actress do to attempt to adapt
to this situation?
• What are the pros and cons of mitigation?
• What are the pros and cons of adaptation?
Climate change mitigation: working to
decrease greenhouse gas emissions in an
attempt to reduce the severity of future
climate change
Climate change adaptation: working to
adjust to the unavoidable aspects of climate
change that we are already experiencing and
may experience in the future
Data from NOAA
Scientists believe that the
number of 100 degree
days per year will increase
during the next century,
depending on greenhouse
gas emissions.
Room for the River
Lowering of
floodplains
Lowering (excavating) an area of the floodplain increases the room for the river at
high water levels.
Deepening
summer bed
The river bed is deepened by excavating the surface layer of the river bed. The
deepened river bed provides more room for the river.
Water storage
The Volkerak-Zoommeer lake provides temporary water storage when exceptional
conditions result in the combination of a closed storm surge barrier and high river
discharges to the sea.
Dike
relocation
Relocating a dike land inwards increases the width of the floodplains and provides
more room for the river.
Lowering
groynes
Groynes stabilize the location of the river and ensure that the river remains at the
correct depth. However, at high water levels groynes can form an obstruction to
the flow of water in the river. Lowering groynes increases the flow rate of the
water in the river.
High water
channel
A diked area that branches off from the main river to discharge some of the water
via a separate route.
Depoldering
The dike on the river side of a polder is relocated land inwards. The polder is
depoldered and water can flood the area at high water levels.
Removing
obstacles
Removing or modifying obstacles in the river bed where possible, or modifying
them, increases the flow rate of the water in the river.
Strengthening Dikes are strengthened in areas where creating more room for the river is not an
option.
