Farm BATs proposal

(IPPC Directive)

OBJECTIVE

Support selecting environmentalstrategies (BATs) in a PARTICULARFARMS

Calculate emissions (NH3, CH4 and N2O), consumptionsand production under different scenarios/strategies

Comparison farm scenarios

Swine, broilers, laying hens and dairy cattle

Particular management and climatic conditions

Whole farm system approach

Inputs well known by farmers

OBJECTIVE

BATs effects on emission and consumptions

(Studies Batfarm project * Bibliography)

Default values, modifiable by users

Regionalizable values (zootechnical, climatic andemission factors)

2 Users: standard/advance

Combination: Emission factors, empiricalequations & process-oriented mechanisms.
