Planning Multifunctional Measures for Efficient Landscape Management: Quantifying and Comparing the Added Value of Integrated and Segregated Management Concepts - Landscape Ecology for Sustainable Environment and Culture - page 256

landscape functions were calculated. It was assessed and compared to what degree
the regional environmental quality objectives were fulfilled by scenario 1 and by
scenario 2. The costs for achieving specific sectoral and multifunctional effects
were compared between the sectoral and integrative scenarios.
13.3.6 Case Study Area and Data Basis
The method for investigating the impacts of different mono- and multifunctional
management strategies on the provision of ecosystem services was tested in the
case study region of Verden County, Germany. Verden covers an area of
approximately 79,000 ha in the state of Lower Saxony, near the city of Bremen.
The landscape is dominated by agricultural land with a high proportion of
grassland along the Aller river floodplain and dominating cropland on the sandy
soils of the moraine area. In addition, moors, fens and marshes are characteristics
of the landscape.
The assessment of landscape functions (status quo) as well as the generation of
the scenarios is based on the landscape master plan of the County of Verden ( 2008 )
and additional environmental information systems from the state government and
accessible www map servers (State Authority for Mining, Energy and Geology;
River Basin Commission Weser). The management concepts do not include the
settlement areas.
13.4 Case Study Results
13.4.1 Effectiveness and Efficiency of the Uncoordinated
Scenario
The sectoral scenarios describe how each of the landscape functions can be
individually optimized. The documentation of the outcomes of the sectoral sce-
narios includes: (1) which environmental quality objectives have been achieved,
and to what extent (2) which measures, i.e. types of measures, are included in the
management concept, (3) the total area where measures are implemented, as well
as (4) implementation costs for a 10 year period (Table 13.3 ). The allocation of the
measures is shown in maps (exemplarily Fig. 13.3 ).
13.4.1.1 Sectoral Scenario for Soil Erosion Prevention
The sectoral scenario for erosion prevention is based on the following underlying
assumptions: (1) The allocation of one type of measure within an area is sufficient
to avoid soil erosion to its full extent. (2) erosion protection measures are required
