Presented by Wilfred Appelman (TNO) at FERTINNOWA's 2nd International workshop "Meeting growers’ needs: Exchanging Technologies on Irrigation and Fertigation" Description: To what point are existing regulations efficient or how regulations deal with the sustainability of the present agricultural production models in terms of water and fertiliser´s use is one of the key questions arising. An inventory of water regulations in Europe, country and region scale, has been performed to detect gaps in policy and possible inconsistencies in its application.
