Wir zeigen auf, dass es einer differenzierten Betrachtung von Eigentums- und Nutzungsstrukturen bedarf, um ein komplettes Bild der Verhältnisse am Bodenmarkt zu bekommen. Wir plädieren dafür, dass die Transparenz auf dem Bodenmarkt erhöht werden sollte um politische Entscheidungen besser zu fundieren und die Ausgangsbedingungen für alle Marktteilnehmer:innen zu verbessern.

🚜 Wem gehört das Land? 🌾 (1/2)
In unserem neuesten Policy Brief werfen Alfons Balmann, Daniel Müller und ich einen genaueren Blick auf das landwirtschaftliche Bodeneigentum in Brandenburg. Unsere Analyse zeigt: Der Boden gehört vielen – eine breite Streuung des Eigentums ist zu beobachten.
5) On the local market, the ownership concentration rarely exceeds common thresholds of market concentration that indicate potential market power. When these thresholds are exceeded, public institutions are often the largest owners.
You can find more interesting facts in the paper; it is Open Access. Enjoy reading!

3) The largest owners are diverse. We identified public institutions, agricultural company networks, and non-profit organizations among the largest individual owners.
4) We find examples of non-agricultural investors owning larger areas, but identifying them was difficult. Also, successor companies to the agriculture productive companies own larger tracts of land. These companies could constitute an entry point for investors to quickly take control of large areas.

Our results:
1) Land ownership is very fragmented, more than the actual land use. This means there are much more landowners than farmers, and ownership parcels are much smaller than the fields. This is similar to other post-socialist regions.
2) More than half of the land is owned by private persons who are not active in agriculture but only own a few hectares on average.

Who owns the agricultural land, and how concentrated is land ownership? Knowledge about this is limited, although being at the center of heated debates. This motivated us to examine land ownership structures for Brandenburg in detail. Read up on our results here: doi.org/10.1007/s10460-024-10590-3

Interested in whether field size increases with farm size? Take a look at this preprint: https://doi.org/10.31220/agriRxiv.2024.00245
We inverted the question to see if farm sizes can be estimated using field sizes, which are more often known. We find a positive relationship, but high uncertainties.
It's a great collaboraitve effort with great colleagues, e.g. @philrufin @pmeyfroidt and others.
Btw, Maximillian Wesemeyer and I share the main authorship, my name only appears first alphabetically.
Happy to share this new study on the relationship crop rotation diversity and landscape diversity and biophysical characteristics. Our study indicates a spatial trade-off between crop rotations and landscape diversity. Led by Josepha Schiller et al. from @ZALF_leibniz
Context Both crop rotational diversity and landscape diversity are important for ensuring resilient agricultural production and supporting biodiversity and ecosystem services in agricultural landscapes. However, the relationship between crop rotational diversity and landscape diversity is largely understudied. Objectives We aim to assess how crop rotational diversity is spatially organised in relation to soil, climate, and landscape diversity at a regional scale in Brandenburg, Germany. Methods We used crop rotational richness, Shannon’s diversity and evenness indices per field per decade (i.e., crop rotational diversity) as a proxy for agricultural diversity and land use and land cover types and habitat types as proxies for landscape diversity. Soil and climate characteristics and geographical positions were used to identify potential drivers of the diversity facets. All spatial information was aggregated at 10 × 10 km resolution, and statistical associations were explored with interpretable machine learning methods. Results Crop rotational diversity was associated negatively with landscape diversity metrics and positively with soil quality and the proportion of agricultural land use area, even after accounting for the other variables. Conclusion Our study indicates a spatial trade-off between crop and landscape diversity (competition for space), and crop rotations are more diverse in more simplified landscapes that are used for agriculture with good quality of soil conditions. The respective strategies and targets should be tailored to the corresponding local and regional conditions for maintaining or enhancing both crop and landscape diversity jointly to gain their synergistic positive impacts on agricultural production and ecosystem management.
