What is CAPRI ?
• Common Agricultural Policy Regionalised Impact analysis
• on regionalised level (NUTS II)
• on whole agricultural sector:
all outputs/inputs covered
• based on a quantitative economic modelling system
• developed and maintained
by an independent network of research institutions
• mainly funded by DG-RSRCH framework programs

CAPRI Modelling system
• Modelling system consists of
• Regionalised data base
• Supply Module
• Market Module
• Exploitation and Reporting tools
CAPRI CAPRI

CAPRI data base
• Combines consistently time series
• at EU/national/regional/farm type level
• on herds/acreages, production, market balances
• on prices, economic accounts
• on input & output coefficients
• on policy instruments

Data sources• As far as possible uniform sources
• EUROSTAT: market balances, slaughtering statistics,
land use statistics, herd countings
• Farm Accounting Data Network:Production program for farm type module,Estimation of input demand functions
• Gaps closed by regional and national statistics
• Input/Output relations, emission coefficients etc. from different sources

Data compilation
• Own “base model” ensures consistent and closed data base
• Gaps are closed and inconsistencies removed
• by simultaneous estimation techniques
• under constraints capturing consistency requirements

Data coverage for Herd Sizes I
• Animal herds for• dairy cows, other cows• cattle raising (male & female calves, raising heifers)• sows• milk sheep & goat• laying hens
yearly averages over all available countings

Data coverage for Herd Sizes II
• Slaughtered heads for
• calves fattening (male/female)• male adult fattening (male/female)• pig fattening• sheep & goat fattening• poultry fattening
• estimates regarding the length of production cycle allow calculation of herd sizes
CAPRI CAPRI

Consistency requirements
• Intertemporal flow model for herds: Slaughtered + herd size changes + exported animals = raised/born animals in t(-1) + imported animals
• Slaughter weight * slaughtered heads = production
• Market balances for meats, milk, eggs
• Fat and protein balances for milk and milk products
• Plausible number of siblings (cows, sows, mother sheep&goat)
• Male/Female relationship for calves
• Plausible slaughter weights and output coefficients

Projections
• “Baseline”:
developments of agricultural markets, prices,yields, input demand, cropping patterns, herd sizes ...
under continuation of current policy setting
• model mechanism + trend analysis+ judgement + careful look at other projections
• model ensures closed balances for inputs and outputs (including nutrients, feed and young animals)
• and matching price developments
