Wow, richtig spannender Artikel zum Thema Rentendebatte und eine Argumentation die mir neu war, ich aber sehr schlüssig finde.

New publication out now! @philrufin.bsky.social, Pauline Hammer et al. mapped 17M fields in Mozambique using deep learning and satellite imagery. With 78% of fields being <0.5 ha, this provides critical data for sustainable land use policies! Read more here: iopscience.iop.org/article/10.1...

$Announcement graphic for a scientific publication in Environmental Research Letters titled "National-scale field delineation in Mozambique refines our understanding of cropland distribution, field size, and deforestation actors" by Rufin, Hammer et al. The central feature is a map of Mozambique color-coded by Mean Field Size, ranging from 0.01 hectares (tan) to 2.50 hectares (teal). Additionally, various maps and statistical graphs regarding mean field size show close-up field boundaries across the country and correlate field size with variables such as cropland fraction, travel time, and population density.

Just published 🌱: We dug into 16 million+ field records across Central Europe to find out what drives farmers’ crop rotation choices. Turns out past cropping, agronomic advice, and legume prices matter a lot and legumes are likely to play a much bigger role in the future👉 doi.org/10.1016/j.ag...

Neue Studie zu #Glyphosat. 💥 👉 "Jeder Haushalt 🏠 trägt dazu bei, dass dieses Gift die Natur belastet." Damit ist die These, dass die hohe Belastung in Gewässern nicht nur aus der #Landwirtschaft 🚜 stammt, sondern zu großen Anteilen aus 🏘 Haushaltsabwässern, bestätigt. Bericht im DLF 📻 👇

Wie Waschmittel zur Entstehung von Glyphosat beitragen

Glyphosat kann nicht nur durch die Landwirtschaft in Gewässer gelangen, sondern auch durch Kläranlagen. Ursache ist ein Bestandteil in den Waschmitteln.

Really cool and informative paper by Fabian Klebl and others on farmers' preferences for where to locate hedges or wildlife strips. Highly recommended (only wrinkle for me: no German case study😕). #biodiversity #agriculture www.sciencedirect.com/science/arti...

Screenshot of paper "Connecting habitats in European agricultural landscapes: Farmers' spatial preferences for linear wildlife corridors" by Klebl, Rhodes, Häfner and Piorr

Abstract: Habitat fragmentation in agricultural landscapes threatens biodiversity. Enhancing landscape connectivity across
cultivated areas requires a thorough understanding of farmers’ spatial considerations and their willingness to
create semi-natural habitats. We therefore conducted a spatial choice experiment with farmers from ten European
countries to assess their preferences for placing linear wildlife habitats (hedgerows and wildflower strips) at
the field scale under different scenarios, as well as the role of farm and personal factors. A total of 471 responses
were analysed using multinomial logistic regression and generalised linear mixed models. The results indicate
that landscape conditions, including field shape, slope, soil quality, and pre-existing landscape features, exert a
significant influence on farmers’ decisions, as do the size of machinery, cultural regions, attitudes towards
biodiversity, and type of intervention. On the other hand, no statistical significance was found for other variables.
In general, farmers’ choices were driven by a desire to minimise disturbance to field work, optimise
productivity, increase biodiversity, and address specific environmental challenges. The insights into farmers’
decision-making from this study can inform ecological network planning to reduce transaction costs by preselecting
likely adopters, and to mitigate resistance and lower financial compensation by identifying best-fit
options aligned with farmers’ practices. Integrating these findings into geospatial models could improve predictions
of the impact of spatially targeted biodiversity conservation strategies on landscape composition and
future biodiversity trends in agricultural areas.

🚜 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.

Who owns the agricultural land, and how concentrated is land ownership? Knowledge about this is minimal, 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/s104...

Africa's population centers are relatively regional and dense, and will likely continue to be so. Whatever infrastructure issues they will have in the future will almost certainly be the same ones they have had for decades, only more so. (Map shows projected population centers in 2050.)

Estimated population density by 2050, with five centers called out: Coastal West Africa, 287 million, Great Lakes Region, 132 million, Nile Delta, 85 million, Ethiopian Highlands, 70 million, Mediterranean Coast, 63 million

Are you interested in whether field size increases with farm size? Take a look at this preprint: doi.org/10.31220/agr... We inverted the question to see if farm sizes can be estimated using field sizes, which are more commonly known. We find a positive relationship, but high uncertainties
