13.4.2.2 Effects of Integratively Planned Measures
Total of regional objective fulfillment
The integrative planning results in achieving or even exceeding the sectoral EQO.
Erosion prevention as well as the targeted CO 2 -retention are fully achieved, whereas
nitrogene-input reduction goes beyond the sectoral target (*133 % of the EQO).
The improvement of biotopes leads to a habitat value that is about 32 % higher than
the habitat value achieved in the sectoral strategy for safeguarding biodiversity. This
is to be expected, because the spatial extent of the measures in the integrative
scenario is larger than any single sectoral concept. However, the area where mea-
sures are allocated can be reduced while still fulfilling the regional objectives. For
example, monofunctional areas for water quality conservation measures on crop-
land (8,905 ha) as well as Level-2 areas for water quality conservation and the
improvement of the biotope function (9,129 ha), could be excluded. Herewith, the
remaining area where measures are necessary is reduced to 41,079 ha.
Proportional regional objective fulfillment in areas of action with different cate-
gories of multifunctionality.
From a cross-sectoral perspective, it appears to be more effective to allocate
measures in areas where it is possible to enhance multiple landscape functions. If
integrative measures are implemented in areas where all landscape functions need
improvement (Level-4 multifunctionality), which is 9 % of the case study area,
each sectoral EQO (quantified for the whole case study area) can be achieved
between a minimum of 8.6 % (for climate protection) and a maximum of *32 %
(for erosion prevention). If, additional, measures are implemented on Level-3 sites
(improvement for three functions), * 34 % of the sectoral objective for climate
protection can be achieved, * 65 % of the sectoral objective for biodiversity,
* 74 % for water and * 92 % for soil protection. These sum up to 264 % that (in
sum of all four sectoral objectives) can be fulfilled, which is about two third of the
regional objectives (in total 400 %) (Fig. 13.4 ). These results can be achieved on
only *37 % of the case study area and 43 % of the total focus area. Areas with
multifunctionality Level-1 or -2 cover 48 % of the case study area. Here, 67 % of
the sectoral objectives for biodiversity can be reached, *59 % for water, *19 %
for climate and *8 % for erosion prevention. The assessment also takes into
account assumed additional benefits for biodiversity in areas where sectoral bio-
diversity measures are not officially required.
Proportional fulfillment of regional objectives related to a reference area unit.
Within a reference area unit of 1,000 ha, the sectoral objectives (accept EQO
for erosion prevention) can be fulfilled to different proportions. In sum, the
regional objective fulfillment varies from 2.3 % in monofunctional areas for water
quality conservation to 14.6 % in Level-3 (EWB) areas (Fig. 13.5 ). The sum of all
sectoral objective fulfillments within the reference area unit of 1,000 ha is in
Level-4 areas and in specific Level-3 areas (EWC) up to six times higher than in
