Students will achieve the analytical tools to interpret agri-environmental issues in an economic perspective; they will be able to discuss in this framework agricultural and agri-environmental policies of the EU.
Students will obtain an understanding of the agronomic techniques that can be applied profitably to mitigate the potential adverse effects of agriculture on the environment. An overview of the agronomical shifts requested to meet the objectives of the agro-environmental policies will also be discussed.
