A close call near Caerleon, near Newport in the lower Usk Valley |
It’s been a bad winter for floods, with the north of England and
southern Scotland getting particularly badly hit, along with parts of Wales,
and we are only halfway through. As has been noted previously there can
be no blank cheque for flood defences; we need to
make rational and cost effective sustainable choices when it comes to coastal
defence. We need to decide how we are going to deal with the weather
related effects of a warming world with expanding and rising oceans.
Now I am not suggesting for a moment the wholesale abandoning of large
tracts of our country to the ravages of the ocean, although unless climate
change is taken on then we may end up facing that eventuality. Rather we
need to make rational long-term sustainable choices about flood defence and the
development of a comprehensive planning system for our country. At a time
when several
of our councils are considering building on known flood plains the issue of
flooding remains important.
We need to actively build in flood
prevention / flood avoidance into as the planning application process and make
efforts to avoid building in those areas that are vulnerable (or will be
vulnerable in the future) to flooding or at least build to take into account
the possibilities of flooding. If we are going to build on flood plains or
other areas that are vulnerable to flooding then we must use
flood resistant or flood hardened modern intelligent design
and building techniques to reduce potential future damage, loss
and inconvenience as is done elsewhere.
The UK mainland has around 5,000 miles
of coastline, not all of which is inhabited or at prime risk, but even so,
going Dutch with wholesale widespread sea defences would be an expensive option
for Wales, let alone the UK. Now those coastal roads and railways that are at
regular risk of being damaged by a combination of bad weather and high tides may
well need to be re-routed.
In Wales we do need to take a longer
view and seriously consider the possibilities of relaying railway lines and
building roads away from those more vulnerable coastal areas. Additionally we
need to harden our power network and our communities to the effect of severe
weather events. That said we are in a much better position to make more
rational coastal defence choices than some countries in the developing world
and to seriously consider just exactly where we put key infrastructure.
The quick fix (and short term gain) may
be one of our biggest problems here in Wales along with the lack of sensible
detailed all Wales development planning. Across the border, Westminster’s
institutionalised short term view led to the cutting of £500 million pounds
from the Environment Agency budget (between 2010 and 2013, and at the time (in
2014) anticipated another ‘saving £ 300 million pounds by 2015 and the cutting
of some 1,500 jobs.
The Pacific island nations and
Bangladesh will face the potentially catastrophic social, economic and
political consequences of rising and expanding oceans before we will.
Even the Dutch have after over 500 years of experience trying come to the
conclusion that in some cases it is better to build in flood room, setting
aside some coastal wetlands and other land as places that will be allowed to
flood to take the pressure of other areas.
Coastal flooding and bad weather may hit some parts of our country hard, other areas may literally dodge the storm, but we may not be so lucky all the time. Westminster budget cuts mean (which are unlikely to be reversed) that in England (in in Wales) there will be less money, less resources and less people to work to prevent future floods. We in Wales cannot afford that short of dull short term thinking... we need to start the process of better flood prevention now before the next time.
