Because traditional planning practices don’t
work when the future is highly uncertain, Deltares
developed climate adaptation pathways. The
most striking element in our consultancy work is
the ‘Underground map’ showing those different
pathways. Each path refers to an interrelated
series of policy changes and investments.
Depending on the developments - objectives
may not be achieved or population growth and
climate change may be faster or slower than
anticipated - it may be decided to switch to a
different pathway or to follow several pathways
at the same time. The points at which decisions
of this kind have to be taken are referred to as
‘transfer stations’. Decisions are taken on the
basis of pre-agreed indicators. Sound, independent
monitoring is an important part of working with
climate adaptation pathways.
