“…Often peatlands prevail, and water levels that are a few decimetres higher or deeper determine the processes of vegetation development, peat growth or degradation, and the site's status as a source or sink of greenhouse gases (Couwenberg et al . , ; Krimly, Angenendt, Bahrs, & Dabbert, ; Lamers et al . , ; Mettrop, Rutte, Kooijman, & Lamers, ; Minke et al .…”

The management of shallow water table sites is often the subject of discussion between different interest groups, the most controversial topic being the different target groundwater levels. A good level of knowledge about the effects of the different water levels on the water budget components is a precondition for the development of compromises in well‐balanced water resource management. We used groundwater lysimeters to investigate the impact of different water level regimes on the water balance. The lysimeters were installed directly within a typical shallow water table site and had a specially designed system to control the lower boundary condition. This enabled us to simulate different management options in a realistic way. Our results show increasing evapotranspiration with higher water levels but only if the vegetation is adapted to these conditions. Adaptation may take place within a few years of higher water levels. High water levels in spring are linked to increased water storage. This can help to compensate for the higher evapotranspiration for some weeks but not for the entire season. The meteorological conditions have a large short‐term impact on the water budget, which is difficult to compensate for using long‐term water management strategies or slow‐responding vegetation development. Our results underline the complex ecohydrological dependencies in such site conditions and could be an important basis for the development or improvement of ecohydrological models.

“…Our results, specific to farms and GHG emissions factors of peatlands in the Boreal pedoclimatic zone in Finland, cannot be directly compared with other studies on farm-level costs of GHG reduction on peatlands in other areas. Krimly et al ( 2016 ) calculated reduction costs for greenhouse gas emission reduction on typical farm types in southern Germany where the average share on peatland on farms was 19%. The farm types and their size were close to the same as in our study.…”

“…Krimly et al ( 2016 ) calculated the GHG abatement costs from peatlands in Germany. According to their results, the conversion of arable land of peat-soil type into medium-drained intensive grassland would lead to high abatement costs up to €92/tCO 2 e, while the abatement costs of the rewetting and conversion as wet grassland would range from 5 to 57 €/tCO 2 e.…”

Drained agricultural peatlands emit significantly higher amounts of greenhouse gas (GHG) emissions per hectare than mineral soils. GHG abatement costs for representative cereals (CF) and dairy (DF) farms in southwestern Finland were estimated by integrating an emission-based tax together with an option to invest in a subsidized adjustable drainage system on peat soils in a farm-level dynamic optimization model. With an average 10% share of peat soils from overall farm area, emissions tax rates over 15 (CF) and 19 (DF) €/tCO2e triggered adjustable drainage investments with a significant reduction in GHG emissions per ha, when assuming no crop-yield effect from the adjustable drainage. Abatement costs for emissions tax rates €12–50/tCO2e/ha were €16–44/tCO2e (CF) and €26–51/tCO2e (DF) for whole farm-soil emissions, depending on the share of peatlands on the farm, on the yield effects of adjustable drainage, and on crop prices. High emissions tax rates imply higher abatement costs since farms have a limited capability to adjust their production and land use. Thus, emissions reductions from peatlands can be achieved at reasonable costs when investing in adjustable drainage on peatlands. The income losses due to emissions tax, however, are high, but they can be compensated for farmers by lumpsum payments independent of their production decisions. Since existing agricultural policies such as the EU CAP system may have limited effectiveness on GHG emissions, the emissions tax and adjustable drainage on peatlands could promote GHG abatement significantly on farms and areas with abundant peatlands.

“…The agricultural census of 2010 provides the relevant regional capacities for the projection to AER level. Schäfer (2006) describes this modeling approach in detail, and a more recent application of EFEM can be found in Schwarz-v. Raumer, Angenendt, Billen, and Jooß (2017), and Krimly, Angenendt, Bahrs, and Dabbert (2016). EFEM results are validated against the agricultural census of 2010 by comparing data on animal numbers, crop production, and land use with statistical data (Suple).…”

Downscaling of agricultural market impacts under bioeconomy development to the regional and the farm level—An example of Baden‐Wuerttemberg

The expansion of the bioeconomy sector will increase the competition for agricultural land regarding biomass production. Furthermore, the particular path of the expansion of the bioeconomy is associated with great uncertainty due to the early stage of technology development and its dependency on political framework conditions. Economic models are suitable tools to identify trade‐offs in agricultural production and address the high uncertainty of the bioeconomy expansion. We present results from the farm model Economic Farm Emission Model of four bioeconomy scenarios in order to evaluate impacts and trade‐offs of different potential bioeconomy developments and the corresponding uncertainty at regional and farm level in Baden‐Wuerttemberg, Germany. The demand‐side effects of the bioeconomy scenarios are based on downscaling European Union level results of a separate model linkage between an agricultural sector and an energy sector model. The general model results show that the expanded use of agricultural land for the bioeconomy sector, especially for the cultivation of perennial biomass crops (PBC), reduces biomass production for established value chains, especially for food and feed. The results also show differences between regions and farm types in Baden‐Wuerttemberg. Fertile arable regions and arable farms profit more from the expanded use of biomass in the bioeconomy than farms that focus on cattle farming. Latter farms use the arable land to produce feed for the cattle, whereas arable farms can expand feedstock production for new value chains. Additionally, less intensive production systems like extensive grassland suffer from economic losses, whereas the competition in fertile regions further increases. Hence, if the extensive production systems are to be preserved, appropriate subsidies must be provided. This emphasizes the relevance of downscaling aggregated model results to higher spatial resolution, even as far as to the decision maker (farm), to identify possible contradicting effects of the bioeconomy as well as policy implications.
