New responsibilities of agriculture: structural differences in stakeholder networks and intentions towards climate change abatement strategies in peatland AgEcon
Hübner, Rico; Kantelhardt, Jochen.
Agriculture is required to fulfil the needs and wants of society in a variety of fields: food supply, environmental services, landscape preservation and finally: climate mitigation. Using the example of land-use change in peatland in order to create possibilities for greenhouse-gas reduction, a survey about the intentions and future expectations of stakeholders was undertaken. The underlying network structure of these stakeholders in three representative peatland areas of Germany was determined and compared. The results show that considerable differences exist in the degree of knowledge about climate change and in the willingness to cooperate. Depending on the area studied, the most influential political entities are different and thus require different...

Reshaping agricultural peatland use climate friendly in selected German regions AgEcon
Schaller, Lena; Kantelhardt, Jochen; Hübner, Rico; Freibauer, Annette; Droesler, Matthias.
About 30 percent of the world’s soil carbon is stored in peat soils. Peatland’s functional principle of carbon storage greatly depends on management strategies. Therefore agricultural peatland use becomes a focal point of interest in the current debate on climate protection. Agricultural management demands a drawdown of the water-level that causes aerobe degradation of the soils, as well as trace-gas emissions which have a negative impact on greenhouse-gas balance. Climate-friendly peatland management strategies, however, demand enhanced groundwater tables and decreased land-use intensity. Against this background we analyse ways of re-organising agricultural peatland use within a case study located in Germany, where intensive peatland use accounts for 2.3...

The Provision of Ecosystem Services by Agriculture – a Spatially Explicit DEA Approach AgEcon
Kapfer, Martin; Hübner, Rico; Eckstein, Karin; Ziesel, Sigrid; Kantelhardt, Jochen.
According to the concept of ecosystem services, agriculture not only provides commodities but also cultural and regulating services. While it is easy to value commodity production by market prices, the valuation of cultural and regulating services is complex because of their public good character. Non-parametric approaches such as the Data Envelopment Analysis (DEA) allow for estimating the contribution of agriculture to such services. However, it is not enough to know the extent of ecosystem services provided; it is also necessary to be aware of which farmers provide these services and where they are provided. In this paper, we suggest a plot-specific approach combining GIS analysis and DEA models. This allows a spatially explicit assessment of...
