Filtration of surface water by ecosystem types - Demand
General description
<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
- <font 14px/inherit;;inherit;;inherit>NOx emissions in the atmosphere.</font>Source: EMEP, http://www.ceip.at/new_emep-grid/01_grid_data_2015
- <font 14px/inherit;;inherit;;inherit>Nitrogen loads from fertilization per different LULC</font>
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>

<font 14px/inherit;;inherit;;inherit>(2) Calculate total N inputs</font>
<font 14px/inherit;;inherit;;inherit>The total N inputs per municipality are therefore obtained summing up the results from point 1 and point 2.</font>
