- 2.1% of Dutch ware potato yield is lost to drought yearly
- 962 kg per hectare is the average annual drought loss
- 73,313 ha of ware potatoes were grown in the Netherlands
- 40% overspend hit phase 1 of the freshwater Delta plan

Dry summers quietly shave a slice off every Dutch ware potato harvest, and the national audit office has now measured it. Over a quarter of a century of data, the average drought penalty is roughly two percent of output, close to one tonne on each hectare. On the 2023 planted area this meant some seventy million kilograms of potatoes never harvested, worth between fourteen and thirty-five million euros depending on the price assumed. The same review shows public water projects slipping by years and running forty percent over budget, so relief from the state will come slowly. Growers on light, non-irrigated soils carry most of this risk, while processors inherit it through smaller and less stable supply. Weather models for 2050 suggest a wider rainfall gap in the growing season. One caution: the figures are long-run averages, and a single extreme year such as 2026 can cost far more than the mean.
Drought has cost Dutch ware potato growers about 2.1% of their yield every year. The finding comes from the Netherlands Court of Audit (Algemene Rekenkamer). The office published a report on freshwater policy on 3 September 2026. Farm outlet Boerenbusiness analysed the crop data on 15 September.
The audit covers 26 years, from 1998 to 2023. It looks at potatoes, onions, cereals and sugar beet.
Losses per hectare and in euros
A 2.1% average annual loss equals 962 kg less potatoes per hectare. In 2023 Dutch growers planted 73,313 hectares of ware potatoes. Across that area, drought removed about 70.5 million kg of potatoes in one year.

The report values this loss at €14 million to €35 million. The range reflects 2023 prices of €0.20 to €0.50 per kg, according to Boerenbusiness. Losses differ by province. They range from about 1.0% to 2.1% per year.
Other crops also lose yield in dry years. According to the analysis, onions lose 1.1% to 2.7% a year. Cereals lose 0.9% to 2.1%. Sugar beet loses 1.5% to 1.6%.
Water measures run late
The audit also reviews the Delta Programme for freshwater. Nearly three quarters of the phase 1 measures are delayed. Measures for the main water system run about three years late on average. Regional measures run 2.4 years late, according to Boerenbusiness.
Costs have also grown. Phase 1 had a budget of €365 million. Actual spending reached €513 million. That is 40% above plan.
Climate scenarios point to more pressure. By 2050, potential evaporation may rise by 6% to 9%. The rainfall deficit from April to September may grow by 13% to 35%. Summers now called extreme could become normal.
The 2026 season shows the risk. Market analysts at DCA estimate the Dutch ware crop at about 3 million tonnes. That is 27% less than last year.
פארוואס עס ענינים
The audit puts a firm number on a cost that growers usually absorb quietly. A loss of almost one tonne per hectare each year adds up over a crop rotation. It also weakens the case for dryland potato growing on light soils.
The delays in water measures matter for storage and processing too. Processors need stable volumes. Irrigation access, water rights and soil moisture will shape contract terms and plant sourcing in the coming years.

וואָס ווייַטער
Dutch freshwater measures remain behind schedule, with main system projects about three years late. Climate scenarios point to larger rainfall deficits by 2050. The 2026 crop, estimated at about 3 million tonnes, will show how far current losses exceed the long-term 2.1% average.
