Overriding objectives (legally
binding)

Environmental quality
objectives for the district scale
derived from overriding
objectives and planning targets

Generally applicable indicators
for assessing environmental
quality and the effects of
environmental measures

Water resources
WFD: good status of
groundwater bodies until
2027 (particularly good
chemical status),
Directives, especially EU
Nitrates Directive,
Drinking Water directive,
Groundwater Directive

For Groundwater: 50 mg NO3/
l maximum concentration
in percolate water below
all agricultural land, for
surface water: 3 mg/l
maximum N-
concentration of influent
water (in case of good
status of groundwater);
explanation: the
environmental quality
objective refers to the limit
of 50 ml/l of nitrogen in
groundwater according to
the Groundwater Directive
(Annex 1). For a given
area, the amount of N-
reduction (kg/ha*a) on
agricultural land that is
required to achieve good
groundwater status can be
calculated.

Reduction of agricultural N-
input (in kg N/ha*a) The
quantified effects of
measures on reduction of
N-input are adapted from
Osterburg and Runge
( 2007 )

Climate protection
United nations framework
convention on climate
change/Kyoto protocol on
climate change, National
strategy on climate
protection: reduction of
GHG-emissions and
safeguarding of ecosystems
as carbon sinks and
storages

The overriding objectives for
lowering GHG-emissions
are not operationalized for
regional or local scale (no
defined emission limits for
GHG). However, it is
possible to estimate the
potential for GHG retention
and emission of landscapes,
especially CO 2 -retention of
(natural) soils and potential
CO 2 -emissions caused by
agricultural land use
(Flessa et al. 2012 ; Saathoff
et al. 2012 ). The reduction
of CO 2 -emissions that can
be achieved by
implementing measures
within a given area is used
as a quality objective

Effects for CO 2 -balance/
reduction of emissions
caused by agricultural land
use and increase in CO 2
retention potential of soils
according to Saathoff et al.
