Methodology
This ETC HE study quantifies and monetizes losses potato production due to tropospheric ozone pollution in 2022 in Europe. It uses the POD6spec methodology and the flux-effect function recommended by the Mapping Manual of the Air Convention. In terms of data sources, Eurostat data on wheat and potato production at level 2 of the Nomenclature of Territorial Units for Statistics (NUTS 2) were used. When not available, regional data were estimated from national production information, using the number of holdings by area category (ha) and by region as a proxy. Crop production data were then spatialised on a grid of 2 km × 2 km using Corine Land Cover land use classes, impacts were calculated at grid level and then aggregated at a country level. Wheat and potato production data from EUROSTAT are used together with international wheat and potato prices calculated by dividing the Gross production value of wheat and potatoes in 2022 by the production quantities, both from FAOSTAT and EUROSTAT.
