the sectoral environmental quality objectives. The second alternative, termed
'priority', is based on limited funds of 10 Mio. € for implementation.
When alternative measures can be chosen (e.g. for water quality conservation
M1-5 on cropland, M2, 5-7 on grassland), then they are used in equal proportion
in the sectoral scenarios.
All sectoral scenarios were overlaid in order to identify areas where measures
for multiple functions overlap. Then the unintentional multifunctional effects were
analysed. Unintentional multifunctional effects can occur in areas where different
sectoral scenarios allocate similar or synergetic measures. They can also arise
when proposed measures for two or more different functions are not similar. For
example, the measure M10 (allocated for climate protection purpose) also has
unintended benefits for the biotope function (increase of biotope value) regardless
if the management concept for safeguarding biodiversity recommends measures
for this site.
13.3.4.2 Scenario of Planned Integrative Measures
The scenario of planned integrative measures (scenario 2) attempts to achieve the
environmental quality objectives of all the landscape functions simultaneously.
The area where measures are allocated ('area for action'), includes all areas for
measures of the sectoral scenarios. The areas for action were classified according
to the number and combination of measures that were identified by the overlay of
the sectoral scenarios. The number of measures that overlap built different cate-
gories, i.e. levels, of multifunctionality in the areas of action. For example, mul-
tifunctional Level-2 is when two measures overlap. In these areas (Level-2 to
Level-4) synergies as well as possible conflicts must be addressed. It was analyzed
whether the multiple (sectoral) objectives could be achieved by implementing
either one specific multifunctional measure or different overlapping measures.
Decision guidelines were documented to make decisions between alternative or
conflicting development objectives transparent.
Corresponding to the procedure applied in scenario 1, two alternatives are
calculated. The ''best case'' alternative refers to the same sectoral environmental
quality objectives as the sectoral scenarios. The ''priority'' alternative is calculated
for limited funds of 40 Mio. €, corresponding to the total amount spent for the four
sectoral scenarios within scenario 1.
13.3.5 Assessing and Comparing Environmental Effects
The quantitative assessment of the scenarios' effectiveness for achieving the dif-
ferent environmental quality objectives used the indicators defined in Table 13.1 .
For each sectoral scenario within scenario 1 the intended effects for the targeted
landscape function as well as unintentional multifunctional effects for other
