Overview
- Introductory CAPRI Training Session and GAMS Tutorial Announcement We are thrilled to announce that this year's Introductory CAPRI Training Session will take place from 23 to 26 September 2024. In addition, we are offering a voluntary GAMS tutorial for those with no prior experience with the GAMS modeling language, scheduled from 27 to 30 August 2024. To participate in the course, please register here. Please note that completing a self-study tutorial is a prerequisite for participating in the course. We look forward to your participation!

- CAPRI Developer Meeting 2024 The Capri Developer Meeting 2024 will take place on the 27th-28th February in Berlin (on the Campus Nord of the Humboldt University; Hannoversche Straße 27, 10115 Berlin. Haus 12. (Room 2.01)). For further information please contact: davide.pignotti@thuenen.de. The aim of the CAPRI Advanced Training Session (Developer Meeting) is to organize knowledge transfer between developers, experienced users and other participants in the form of presentations on various new developments in CAPRI. Participants will be informed about the relevance, underlying theory, data and technical implementation and will have the opportunity to discuss the new modules. Here you can find the agenda.

- GAMS pre-course as part of the CAPRI online Training Session 2023 successfully completed!!! The GAMS beginners course took place from 6th-8th September. In three days, 15-20 participants learned the basics of the mathematical programming language GAMS and how it can be used to describe the supply side of CAPRI using a didactic model.

Agricultural land use and environmental indicators at 1x1 km grid resolution- Stocking Densities
Main Contributor: Wolfgang Britz
The stocking densities are estimated for the animal production activities found in the CAPRI data base
- Dairy cows
- Suckler cows
- Male calves under 1 year for breeding
- Female calves under 1 year for breeding
- Male calves under 1 year for fattening
- Female calves under 1 year for fattening
- Heifers for breeding
- Heifers for fattening
- Bulls for fattening
- Sows
- Pigs for fattening
- Laying hens
- Poultry fattening
- Sheep and goat for milk
- Other sheep and goat
Attention: CAPRI uses a flow concept to define the activity levels for animal production processes. For fattening activities, the activity level is defined as the number of slaughtered animals. For raising activities, the activity level is equal to the number of raised animals. These activity levels are not equal to average annual herd sizes, but can be converted by taking into account the number of production cycles per year.
The fattening and raising processes are defined per slaughtered or raised animal, and not per number of animals present at a certain point in time. For the maps, the data for the animal activities are firstly converted to livestock units, and then aggregated to ruminants (cattle, sheep and goat), non-ruminants (pigs, poultry) and total animals, measured in livestock units.
The estimation process is based on regressions of data from the Farm Structure Survey 1999 plus climate, soil, slope and altitude data. Those regressions models are used to define a forecast and its error per HSMU which serves as the a priori density entering a Highest Posterior Density estimator. The latter choses the stocking density per cluster of 1×1 km pixel cells which comes closed to the a priori forecast under the condition that the regional numbers reported in FSS are recovered.
