Obiettivi formativiTo provide students with an economic approach to environmental issues in agriculture.
To analyze the main interconnections between agricultural production systems and the environment.
Risultati dell'apprendimento attesiGiving to students the analytical tools to interpret agri-environmental issues in an economic perspective; discussing in this framework agricultural and agri-environmental policies of the EU.
To give an understanding of the agronomic techniques that can be applied profitably to mitigate the potential adverse effects on the environment. To give an overview of the agronomical shifts requested to meet the objectives of the agro-environmental policies.
Agro-environmental economics Revision of basic economics Market as an efficient resource allocation mechanism. Pareto optimum. Efficiency and equity. Kaldor-Hicks compensation principle. Market failures: public goods, externalities, open access resources; Externalities. Externalities as a reason for not reaching a social optimum. Optimal level of externalities. Policy interventions on externalities: market, standards, taxes, subsidies, marketable permits. Public goods. The economic measurement of benefits from public goods. Valuation methods of the benefits of public goods. Agriculture and environment. Positive and negative externalities associated to agricultural production. Structural and technical evolution of agriculture and its impact on environment. Sustainable agriculture and multifunctional agriculture. The Common Agricultural Policy and the environment. Agro-environmental measures and the greening of the CAP. Agro-environmental agronomy Environmental effects of agriculture; the DPSIR scheme for the interpretation of the environmental impact The water compartment and legislative framework (European Water Framework Directive – WFD – 2000/60/EC; vulnerability indices to nitrates and pesticides; national and local policies) Balance of fertilizers (in detail of nitrogen) in agricultural production systems at different scales; impacts of wrong agronomic practices; the strategy to reduce nitrogen release to surface and groundwater Impact of use of pesticides (in detail herbicides); point and diffuse pollution-sources; environmental fate of herbicides; agronomical practices for mitigation of contamination of water and other compartments Examples of agricultural systems and their environmental impacts (main agricultural systems adopted in Italy; comparison between conventional and organic farming; basics of crop rotation; intercropping; cover crops; catch crops, .....)
