Contents The program covers the main themes of the environmental and resource economics. Moreover, topics related to the administrative technical procedures useful for the future of students are also present.
Reference texts Environmental and Resources Economics, Pearce e Turner.Additional materials (lecture notes and articles) will be provided.
Educational objectives The main objective of the course is to provide the students with the appropriate basis for analyzing the environmental sustainability of a zootechnical system as well as the procedural management related to professional practice. Specifically, the main acquisitions will be:
- thorough knowledge of the principles of sustainability and precaution;
- knowledge of administrative procedures related to sustainable management in the livestock sector (EIA, SEA, ecc…);
- basic knowledge of the themes related to the sustainable management of natural resources;
- knowledge of the fundamentals about the economic and environmental sustainability of the energy valorization of biogas;
- knowledge of the authorization procedures of biogas energy production plants.
The course focus on the development of students’ skills in:
- analyze a human system for the purpose of assessing sustainability;
- identify and evaluate impacts caused by human activity on a natural system;
- identify, analyze and evaluate the economic and environmental benefits of a biogas plant.
Prerequisites Basic knowledge of micro- economics are required.
Teaching methods The course is organized as follows:
- Frontal lessons about all subjects in the course.
- Seminars on specific topics related to the course program and held by experts on the subject. Possible seminars: environmental sustainability, food security and sovereignty; other topics will also be identified in agreement with the students.
- Exercises in the classroom: real cases will be analyzed on zootechnical issues of interest for the course, such as: EIA applicability in the field of zootechnics; Compilation of an impact matrix (Leopold matrix); External SEA compatibility analysis; Estimation the economic viability of a biogas plant.
Learning verification modality Oral examination (about 30 minutes), aiming to check the level of knowledge and skills the student has achieved on the theoretical and methodological topics presented during lessons and reported in the program. As a whole, the oral exam will also allow for verifying the student's communication skills and language ownership.

• green marketing;
• the LCA approach;
• green public procurement
Environmental procedures in the public domain

Teaching methods Lectures: 40 h

Laboratory practices: 12 h.

Seminarial/field activities: 2 h.

Slides are used.

Tutorial material distributed by the teacher.
Learning verification modality Final oral exam focused on theoretical lessons and practical lessons for approximately 30 minutes.
The questions will be about the characteristics of livestock waste and possible environmental risks associated with their agricultural reuse. In addition, the knowledge about the treatments will be verified.
Extended program Program:

Provide knowledge of livestock waste characteristics. Identify the problems related to waste disposal in the field and the agronomic potential of treated livestock waste.
