| Résumé : | Intensive agriculture causes many forms of environmental pollution. In this work, a method of coupling agronomic and economic models is used to analyse the effect of different agro-environmental policies addressing nitrate pollution. The scale has been selected to focus on the farm response to different policies. The study covers two typical farms in the Apulia region (Southern Italy), the first in Brindisi and the second in Cerignola. The 14-hectare Brindisi farm grows the following horticultural crops: tomato, lettuce and sweet melon. The Cerignola has an area of 30 ha and is under cereal crops like wheat, sorghum, maize and sunflower. Different levels of irrigation and nitrogen were introduced. The agronomic model CropSyst was used to simulate yield and nitrate leaching. These outputs, in addition to other economic outputs, were used as inputs in a non-linear optimisation model written in GAMS language with the objective of maximising the farmer's income. A multi-criterion approach was used to analyse the impacts of agricultural policies on the reduction of nitrate pollution: increased water pricing, subsidies for cross-compliance activity, flat-rate and block-rate taxes onN-fertilisers. A 50 percent reduction of pollution on cereal farms indicates that water pricing has a social cost of €5 per ha-1; flat-rate taxes have a social cost of €27 per ha-1, the social cost of cross-compliance is also €27 per ha-1 and block-rate taxes have a cost of 31 Euros per ha-1. The results for horticultural farms indicate that block-rate tax has a social cost of €337 per ha-1, that of water pricing is €509 per ha-1, the social cost of cross-compliance is €652 per ha-1 and flat-rate taxes €1127 per ha-1 |
