The Netherlands is the world's second biggest exporter of agricultural products, by value. The one sector represents almost a ⅕th of total exports. Crop irrigation becomes one of the first things to curtail.
A key problem however that arises from the Dutch treating water as a too much problem for their entire history is the population as a whole seems entirely devoid of knowledge on water conservation actions. Even simple stuff like watering plants at the right time of day.
