Adapting transport infrastructure to climate change
The role of standardization
Madrid, 18 January 2015
Climate change adaptation needs
of the core transport network in Spain
Alberto Compte
Objective of my presentation
To extract some conclusions
that might be relevant for your
work,
from the analysis that was
carried out in 2013 by a
working group set up jointly by
the Spanish ministries of
transport and environment.
Your objective at this stage
To establish a list of priority standards that need to be developed
or revised in relation to adaptation to climate change within the
transport infrastructure sector.
Your objective at this stage
To establish a list of priority standards that need to be developed
or revised in relation to adaptation to climate change within the
transport infrastructure sector.
Conclusions extracted
1) The selection of priority standards (and, later, the development of
standardization) should take into account that adaptation needs
are not the same in all Europe.

Conclusions extracted
1) The selection of priority standards (and, later, the development of
standardization) should take into account that adaptation needs
are not the same in all Europe.
2) From the perspective of integrity of new infrastructure, adaptation
can be basically addressed by means of:
• incorporating climate as a variable design parameter,
with a focus on assets with long service lifetime.

with a focus on assets with long service lifetime.
3) From the perspective of its operation, adaptation of transport
infrastructure demands not only to incorporate climate as a
variable design parameter but:
• updated maintenance protocols and contingency plans,
supported by efficient weather warning systems, and
• a vulnerability and risk assessment of existing
infrastructure.
About adaptation needs
Adaptation needs in Spain differ partially from those considered
for transport networks in other Northern and Central European
countries.

 To review standards and recommendations for the design of
cut slopes & embankments in linear infrastructure to reduce
their vulnerability to a combination of droughts and higher
run-off and flash floods.
