they support the objectives of other sectoral strategies. Areas with multifunctional
measures cover 38 % of the total area for measures within the sectoral strategy for
erosion prevention, 22.8 % of the area for safeguarding biodiversity and 19.4 %
within the climate protection concept. However, the spatial overlap of multi-
functional measures is unclear for the sectoral scenarios for water quality pro-
tection and in part for erosion prevention. For these scenarios, the measures are not
necessarily site specific and their spatial allocation is not determined. Therefore,
they are difficult to include in the spatial analysis.
Furthermore, some measures are not compatible and present difficulties for the
combined implementation of the sectoral management scenarios. Some combi-
nations of measures cannot be implemented (e.g. M6 and M14 cannot be imple-
mented simultaneously).
13.4.2 Scenario of Planned Integrative Measures
(Scenario 2)
13.4.2.1 Multifunctionality Levels of Areas
Areas of multifunctionality levels 2, 3 and 4 occur in different combinations and
extent (Table 13.4 ). Level-4 areas are always located on cropland, because a need
for protection against soil erosion exists exclusively on cropland and on small and
rare sites with uncovered soil. They extent on 20.6 % of the cropland (6,312 ha),
which is 9 % of the study area. In these areas, measures are implemented that
contribute to the optimization of all landscape functions. Level-3 areas are located
on agricultural land, including cropland and grassland. Here, three sectoral mea-
sures overlap in different combinations and extent (694-10,905 ha). A coincidence
of improvement requirements for two landscape functions (Level-2 areas) occurs
on almost half of the area for action (18,154 ha, about a quarter of the case study
area), in four different combinations. Areas with improvement requirements for
only a single landscape function (monofunctional areas) are predominantly
restricted to areas with water protection objectives (8,905 ha). In fact, on these
sites (about 1/5 of the areas in the sectoral scenario of water quality conservation
measures) water quality conservation cannot be implemented integratively with
other measures for other landscape functions. Also on 5,922 ha (especially in
forests), biodiversity measures cannot be integrated with other objectives because
no respective need for water, soil or climate restoration has been identified in these
areas. On about 10,727 ha (15.4 % of the case study area), no measures are
required, but the status quo needs, in part, to be safeguarded.
The integrative scenario includes measures for all areas for action (59,113 ha),
regardless their multifunctional level and contains monofunctional areas.
The planning guidelines on how integrative measures are generated and allocated
within the categories of the area for action are listed briefly in Table 13.4 .
