The use of climate services to support decision makers in incorporating climate change adaptation in their
practices is well established and widely recognized. Their role is particularly relevant in a climate sensitive sector
like agriculture where they can provide evidence for the adoption of transformative solutions from seasonal to
multi-decadal time scales. Adaptation solutions are often expensive and irreversible in the short/medium run.
Accordingly, end users should have a reliable reference to make decisions. Here, we propose and apply a
methodology, co-developed with service developers and a representative potential user, to assess the value of the
IRRICLIME climate service, whose information is used to support decisions on climate smart irrigation investment
by water planners in a sub-irrigation district in Italy. We quantify the value of the information provided by
the climate service, that we consider the intrinsic value of the service, or the value of adaptation. We demonstrate
that under three different climate change scenarios, the maximum potential value of IRRICLIME could range
between 2,985 €/ha and 7,480 €/ha
