Notes: The dataset comprises unbalanced panel data from 410 farms for the years 2009–2020 (⁠|$N = 2,341$|⁠). More detailed statistics can be found in Jan et al. (2024).

We use the agricultural production zone, the altitude of the production site and the production system only as controls in the estimation approach using the Frisch–Waugh theorem, since these are variables with almost no temporal variation.

Cattle include cattle breeding and fattening, including dairy cattle culling but excluding milk and dairy products.
