Title:Typology of agricultural land systems of Germany at a resolution of 100 hectares.
Alternate Identifier:DOI PLACE HOLDER
Abstract:

The decline of farmland biodiversity has widely been recognized in society and politics. Many factors that negatively affect biodiversity are associated with agriculture. European policy instruments and measures, which aimed at mitigating these impacts, have not been successful in counteracting the negative trends of farmland biodiversity. There is a growing recognition that conservation policy instruments need to be spatially targeted, given the heterogeneity of agricultural landscapes and extent of agricultural intensification in Europe.

For Germany, we developed a typology of agricultural land systems (ALS) that captures the regional characteristics of agricultural intensification. For this purpose, we applied a cluster-analysis integrating indicators for land cover, landscape structure, land-use intensity, climate and relief at a resolution of with a spatial resolution of 1 km².

As a result, we present a typology of eight ALS ranging from large-scale, intensive arable farming to extensive grassland/forest mosaics in mountains.

The data included in this package contain the typology ALS and the corresponding values for the indicators for each hexagonal grid cell of 1 km²cell size.

The typology of ALS could be used as a spatial framework for regional targeting of conservation policy instruments and for monitoring regional-specific trends of biodiversity indicators and their drivers.

The data are supplement to the publication: Pingel, M.; Sietz, D.; Röder, N., Klimek, S.; Golla, B. (2022, in prep.): Typology of agricultural land systems to support targeted biodiversity measures: A case study from Germany. (Citation will be added upon publication).

Methods and protocols used in the collection of this data package
Description:

1) All indicators were resampled to a hexagonal grid of 100 ha resolution covering the land area of Germany, Projection: ETRS89 / UTM zone 32N (EPSG: 25832) (Perić et al., 2022: Geografisches hexagonales Gitter mit 1 Quadratkilometer Zellengröße...)

Data Source
Perić et al., 2022: Geografisches hexagonales Gitter mit 1 Quadratkilometer Zellengröße für Deutschland - Geographical hexagonal grid with one square kilometer cell size for Germany
Description:

2) Land cover features were obtained from the Basic Digital Landscape Model of the Official Topographic Cartographic Information System of Germany (ATKIS Basic DLM) provided by the German Federal Agency for Cartography and Geodesy, publication year 2017 (BKG, 2017). For each hexagon, the proportion of land cover features of interest were calculated and then attributed to six land cover classes: arable land, permanent crops and horticulture, grassland, forests, settlements (built-up areas for industry and commerce), semi-natural habitats (heaths, bogs, swamps, wetlands, small woody habitats, wasteland).

Data Source
BKG, 2017: ATKIS Basic Digital Landscape Model (2017)
Description:

3) The Shannon diversity (sh_div) was calculated for each hexagonal grid cell using the proportion of 15 land cover classes to describe the diversity of land cover. The Shannon diversity was calculated based on ATKIS Basic DLM objects (BKG, 2017) using the function ‘diversity’ from R-package ‘vegan’ version 2.5-7.

Calculation of edge density (edge_den) and mean patch size (patch_size) was based on land cover features classified as farmland (arable land, grassland, permanent crops and horticulture). Edge density was obtained by summing up the total length (m) of all farmland feature edges within each hexagon. The length was corrected for the size of the hexagon and the coverage of the ATKIS Basic DLM (BKG, 2017) to obtain values in the unit m/ha.

Mean patch size was calculated by averaging sizes of all farmland features that intersected the corresponding hexagon. To avoid that extreme mean patch sizes distort the cluster analysis, we set the maximum of mean patch size to 148 ha, which corresponds 99th percentile of the distribution.

Hexagons that did not intersect farmland polygons got empty values for edge density and patch size and were excluded from the cluster analysis.

Description:

4) Yield dependent variable input costs (vc) were obtained from the Kuratorium für Technik und Bauwesen in der Landwirtschaft e.V. (KTBL, 2020: Standarddeckungsbeiträge) and from the Bavarian State Research Center for Agriculture (BLfL, 2020: Deckungsbeiträge und Kalkulationsdaten) for machinery. Data on natural yields were provided for the main crops by the German statistical office (DeStatis, var. years: Fachserie. 3, Land- und Forstwirtschaft, Fischerei. Reihe 33, Landwirtschaftliche Bodennutzung und pflanzliche Erzeugung") for the main crops and by the Federal Office for Agriculture and Food (BLE, var. years: Milcherzeugung und -verwendung) for milk yield per dairy cow at the spatial resolution of counties. Data on the distribution of the main agricultural production systems at the municipality level were obtained from Neuenfeld et al., 2020: Thünen-Agraratlas.

For the analysis, we used the land-use data for 2016 and for the cost data the 5-year annual average for the period 2014-2018. For this study we did not consider labour costs.

We differentiated variable costs for five major production systems based on the farming typology used in the farm accountancy data network (Commission Regulation (EC) No 1242/2008). The following systems were differentiated:

(vc_arable) Arable cash crops (including cereals, legumes, potatoes, sugar beets, field vegetables, oil rape seed, forage crops).

(vc_perm) Permanent crops and horticulture (including fruits, grapevines, hops, horticultural products, short rotation forestry).

(vc_pig_poultry) Pig and poultry farming.

(vc_dairy) Dairy farming and intensive beef fattening (including: dairy cows, bulls, corn for biogas production). Costs associated to the production of heifers, grass, hey and silage are attributed to this type.

(vc_extens) Extensive livestock farming (including pasture management of suckler cows, sheep, goats and horses).

To avoid distortion of the cluster analysis values for variable costs exceeding the value of the 99th percentile were set to the 99th-percentile value. This step was necessary for all production systems except for arable cash crops (vc_arable).

5) Climate data were obtained from the Climate Data Center of the German Weather Service (DWD, 2020) for the years 2000 to 2019. The following indicators were calculated using grid-based data on monthly mean temperatures and monthly potential evapotranspiration (resolution: 1 square-km):

(annual_temp) Mean annual temperature,

(temp_seas) temperature seasonality (i.e. the difference between monthly means of July and January),

(transp_mar) potential evapotranspiration of March.

Description:

6) For describing topographic relief heterogeneity, the Terrain Ruggedness Index was used. The calculation of the Terrain Ruggedness Index was based on the digital terrain model at a resolution of 200 m (DGM200) provided by the German Federal Agency for Cartography and Geodesy (BKG, 2019) and conducted using the RGDAL function in QGIS version 3.4.15.

Description:

7) Masking: Hexagons were excluded from cluster analysis if they matched one of the following criteria:

a) Hexagons at national borders that covered less than 20% of the German territory

b) Hexagons with missing values for any indicator

c) Hexagons that contained less than 5 % of hexagon area covered by arable land, grassland, permanent crops and horticulture, and semi-natural habitats (see step 1))

The masked hexagons were classified by the proportion of land cover features as follows: Urban (X1): > 50 % settlements, Forests (X2): > 75 % Forests, Others(X3): all remaining hexagons.

Description:

8) Cluster analysis for typification: All indicators were z-transformed to zero mean and standard deviation of 1 before clustering. Clustering was done using k-medians, a partitioning algorithm implemented in the R package 'flexclust'. We used the ‘stepFlexclust’ function implemented in 'flexclust' using a cluster number of k = 8.

Abstract:

The aim of a biodiversity monitoring in agriculture is to continuously provide data with a high spatial-temporal resolution and scientific quality. In order to develop a model for further implementation, important steps are taken in this project: i) the characterization of agricultural areas in Germany; ii) the coordination and definition of agro-area specific goals and (iii) examining and agreeing on relevant sets of indicators. To address the first step, the JKI conducted a systematic literature review of existing landscape characterization approaches at the national and European scale and developed criteria to evaluate these approaches.

The project is supported by funds of the German Government’s Special Purpose Fund held at Landwirtschaftliche Rentenbank.
