The International Association of
Dredging Contractors (IADC) has released its ‘Facts
About’ publication on Coastal Protection.
‘Facts About’ is a series of concise,
easy-to-read leaflets which give an effective overview of essential facts about
specific dredging and maritime construction subjects.
Each leaflet provides a kind of
‘management summary’ for stakeholders who need a quick understanding of a particular
Coastal protection spans interventions,
structures and measures protecting coastal areas and their inhabitants against
flooding, a need amplified by urbanization and development to handle global
population growth combined with the effects of climate change..
A report by the United Nations predicts
the world’s population living in urban areas will increase by over two billion
people by 2050.
The largest share of city dwellers will
live in vulnerable coastal floodplains and half of the world’s population is
projected to be living within 100 kilometers of a coast.
Climate change contributes to the
observed trend of increased storm intensity and many coastal zones around the
globe are already exposed to tsunami risks. The destructive capacity of such
natural events has been witnessed, especially with hurricanes such as Katrina
in 2005 and Harvey in 2017 as well as the tsunamis in Indonesia in 2004 and
Fukushima in 2011.
Soil subsidence of inhabited coastal
floodplains is also occurring in many locations. All these trends combined
demonstrate the need for sustainable and resilient flood protection measures.
