Filtration of surface water by ecosystem types - Demand

<font 14px/inherit;;inherit;;inherit>General description</font>

<font 14px/inherit;;inherit;;inherit>The Water Filtration demand indicator describes the amount of nitrogen that is introduced into the ecosystem per municipality in kg/year. This includes the nitrogen emitted in the atmosphere and then deposed in the landscape and the nitrogen from the fertilization in agriculture.</font>

Input Data

Calculation processes

<font 14px/inherit;;inherit;;inherit>(1)Calculate N emissions per municipality </font>

<font 14px/inherit;;inherit;;inherit>The Emep gridded data on NOx are used to calculate the average emissions at the LAU2 level, these data are after converted in N equivalent as described in Umweltbundesamt (2017)</font>

<font 14px/inherit;;inherit;;inherit>(2)Calculate N inputs based on LULC</font>

<font 14px/inherit;;inherit;;inherit>The N loads quantities per agricultural areas are based on literature (Bundesministerium für land- und forstwirtschaft, umwelt und wasserwirtschaft, 2017), the average N input per municipality is then calculated.</font>
