In this study, quantitative models of the
agricultural sector and nutrient transport and cycling are
used to analyse the impacts in the Baltic Sea of replacing
the current Greening measures of the EU’s Common
Agricultural Policy with a package of investments in
manure handling. The investments aim at improving
nutrient utilization and reducing nitrogen leaching, based
on the assumption that lagging farms and regions can catch
up with observed good practice. Our results indicate that
such investments could reduce nitrogen surpluses in
agriculture by 18% and nitrogen concentrations in the
Baltic Sea by 1 to 9% depending on the basin. The
Greening measures, in contrast, are found to actually
increase nitrogen leaching.
