Filtration of surface water by ecosystem types - Demand

General description

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.

Input Data

Calculation processes

(1)Calculate N emissions per municipality

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)

(2)Calculate N inputs based on LULC

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.

(3) Calculate total N inputs

The total N inputs per municipality are therefore obtained summing up the results from point 1 and point 2.
