The annual irrigation water requirement varied according to farm type (dairy, arable/pig and potatoes), location,soil type and especially year with more than 300%. Abstraction permits based on average values are deemed less suitable as they may restrict farmers’ production in one out of two years. When considering that many farmers’irrigation capacity is limited to about 3 mm/day, abstraction permits covering the irrigation requirement in 8 out of 10 years seems more appropriate in areas with sufficient water resources.
