The environmental impact of the agricultural sector: assessment methodologies toward a circular economy perspective (2020)

ECTS credits:
5 ECTS

Course parameters:
Language: English
Level of course: PhD course
Time of year: Fall 2020
No. of contact hours/hours in total incl. preparation, assignment(s) or the like: The course includes preparation by reading material of about 45h, 35h lectures, solving exercises related to the lectures and independent work 45h. Total work load about 125h.
Capacity limits: The course has a capacity limit of about 20 participants.

Objectives of the course:
The objective of the course is to introduce the students to state-of-the-art of the environmental impact of the agricultural sector and to do so in light of possibilities and shortcomings. The course will include an overview of the main environmental impacts generated the agricultural sector. In particular, the effect of the agricultural sector on greenhouse gas emissions, land, water and heavy metals will be addressed. Moreover, a detailed introduction of the methodologies/indicators used to estimate the environmental impact of the agricultural sector will be provided. Several case studies at different level of analysis (global, national, product) will be investigated. The students will receive a basic understanding of the applied assessment techniques with practical exercises. The course will also include training of the students’ in presenting research in the form of short oral presentations at international workshops and conferences.

Learning outcomes and competences:
At the end of the course, the student should be able to:

  • Know the main environmental impacts associate with the agricultural sector
  • Discuss impact of agriculture on health, environment and climate
  • Know the basis of various methodologies/indicators estimating the agricultural impacts
  • Select a monitoring strategy for various types of agricultural impacts
  • Evaluate the agricultural impacts at different level of analysis
  • Discuss the strengths and weakness of various impact assessments
  • Understand the basic data sources and approaches for data analysis
  • Interpret results from various measurements

Compulsory programme:
The lecturing takes place as a five days intensive course. Prior to the course the student are expected to have read the listed literature. During two of the evenings at the course the students are expected to present short oral presentations in connection with the lessons. During the course, the students will carry out basic assessments by using methodologies presented at the course. After the course, the students need to produce a written report with essays on various topics as well as all calculation exercises from the course. Exercises may be solved in hand, by excel or by programming. In the material provided for the students there will be a short introduction to LCA, IPCC inventory methodology and virtual land and water trade calculation. In the reports, the students are expected to add explanatory text to demonstrate their understanding of the exercises. Details on the exercises are given in the course description.
