Structural Change and Landscape Appearance AgEcon
Kapfer, Martin; Ziesel, Sigrid; Kantelhardt, Jochen.
Our study examines the potential developments of cultural landscapes, taking into consideration various economic and social conditions (scenarios). The study takes place in three project regions which represent typical landscapes in Southern Germany and Austria. In each project area, the influence of a changing economic and political framework is analysed. The following scenarios are defined: (1) status quo (current economic and agri-political framework); (2) high-producer prices and constant (or even increasing) direct payments; and (3) low-producer prices and no (or very low) direct payments. In all three regions, potential production responses are estimated for all farms and aggregated on a regional level. The estimation takes into account social and...

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...

A method to calculate economic key figures with regard to plot structure improvements AgEcon
Kapfer, Martin; Kantelhardt, Jochen.
The aim of land consolidation projects is to improve the competitiveness of agriculture. Since land consolidation is subsidised by national and European means, the effectiveness of such measures must be determined. The following paper presents a method which makes it possible to calculate the direct economic effects of land consolidation. The calculations, considering labour demand, machinery costs and headland effects, compare the economic situation before and after land consolidation. The method was applied to four land consolidation projects in Bavaria. It can be shown that, to a varying degree, land consolidation in the studied areas leads to a substantial decrease in labour demand and machinery costs.

QUANTIFIZIERUNG OKONOMISCHER WIRKUNGEN DER FLURNEUORDNUNG - EIN VERGLEICH AUSGEWAHLTER STUDIEN - (German) AgEcon
Kapfer, Martin; Kantelhardt, Jochen.
Dieser Beitrag vergleicht verschiedene aktuelle Studien zur Bewertung der direkten ökonomischen Wirkungen von Flurbereinigungsverfahren für die Landbewirtschaftung. Alle Studien basieren auf Modellrechnungen und sind als "Vorher-Nachher"-Vergleich angelegt. Methodisch unterscheiden sich die untersuchten Studien vor allem hinsichtlich des Abstraktionsgrades bei der Abbildung der Feldstruktur und der Produktionstechnik. Auch in Bezug auf die erzielten Ergebnisse sind deutliche Unterschiede festzustellen. Entscheidender Faktor hierfür ist neben einigen methodischen Einflüssen die Struktur der landwirtschaftlich genutzten Fläche in den betrachteten Flurneuordnungsgebieten. Eine Flurneuordnung ist aus landwirtschaftlicher Sicht besonders vorteilhaft, wenn die...

ESTIMATION OF COSTS FOR MAINTAINING LANDSCAPE ELEMENTS BY THE EXAMPLE OF SOUTHWEST GERMANY AgEcon
Kapfer, Martin; Kantelhardt, Jochen; Osinski, Elisabeth.
In comparison to large-scale natural landscapes separated from extensively used agricultural production landscapes in North America or Australia, German and Central Europe landscapes are all charac-terised by predominantly agricultural landscapes with few "rests of nature". Due to the high population density, different types of land users demand different functions of the landscape. In addition to food production, there is a high demand for protection of cultural heritage by caring for e.g. hedge-rows in the landscape. The aim of this study was to estimate the costs arising from the maintenance of landscape elements in landscapes situated on land with different site conditions. As an example, the distribution of hedgerows on sites of varying agricultural...

Impact of the CAP Reform on Small-Scaled Grassland Regions in Bavaria, Germany AgEcon
Roeder, Norbert; Kantelhardt, Jochen; Kapfer, Martin.
The CAP reform of 2003 will change farmer's business environment in Europe. This paper analyses the impact of the reform on the land use in southern German grassland regions. The assessment will be based on model calculations for two typical grassland regions. Each study area represents one village with its specific farm structure and natural conditions. These regions differ in their excellence with respect to agricultural use. In Southern Germany small to medium sized family farms is the most frequent type of farming. We use a regional land-use model that conceives farms as independent agents aiming at maximum individual utility. Farm agents optimize their farm organisation with the help of a linear-programming algorithm that takes into account natural,...

Impact of the CAP reform on small-scale grassland regions AgEcon
Roeder, Norbert; Kantelhardt, Jochen; Kapfer, Martin.
This paper presents a regional land-use model that conceives farms as independent agents aiming at maximum individual utility. Farm agents optimize their utility with the help of a linear-programming algorithm that takes into account natural, economic and personal restrictions. Interactions between farms take place on the land market, which is modelled as an equilibrium market. The model is applied in three typical grassland regions in southern Bavaria. The results indicate that the CAP reform of 2003 has various significant consequences for grassland use. In particular, the decreasing profitability of dairy farming will lead to low-intensity forms of grassland use, including mulching. In general, land rents will increase due to the effects of decoupling.
