Regulating nonpoint-source pollution from agriculture: an integrated modelling analysis.

摘要

This paper analyses a set of policy measures oriented towards reducing losses of nitrogen, phosphorus, and soil from agricultural land. An interdisciplinary modelling system, ECECMOD, is presented and a set of policy scenarios analysed. The analysesare oriented towards comparing the effects of input-oriented measures (fertilizer taxes) and policy measures directed towards more direct changes in the agronomic practices conducted on the farm. The effects on emission levels, abatement costs, and distributional effects are documented. The trade-offs between precision and regulation costs are discussed.
