Nitrogen and Sustainability


Admission requirements

This course is an elective module for the MSc Programme on Governance of Sustainability, and also open to students from the MSc Industrial Ecology


The Netherlands experiences a nitrogen and sustainability crisis since the judgment of the council of state in May 2019 about the programmatic approach nitrogen (PAS). This is a good example of the conflicts of interest between the economic growth on the one side and nature quality on the other. During this course you will be introduced to the complexity of the issue through lectures on the historical background of the nitrogen issue, the legislative and juridical aspects, the role and interest of different stakeholders and the role of politics. Furthermore, by using the Nitrogen Footprint model you will learn about the consequences of your consumption pattern for the nitrogen losses to the environment.

Course objectives

After this course you have/are able to:

  • Evaluate the different aspects and drivers in the nitrogen challenge and quantify the impacts of food and lifestyle choices on sustainability

  • Weigh the balance between economic benefits and ecological benefits and give concrete examples

  • Analyze the roles of different stakeholders in nitrogen management and sustainability and its success and failure

  • Use and evaluate Nitrogen Footprint model

  • Develop future policies and possible solutions related to sustainability


You will find the timetables for all courses and degree programmes of Leiden University in the tool MyTimetable (login). Any teaching activities that you have successfully registered for in MyStudyMap will automatically be displayed in MyTimeTable. Any timetables that you add manually, will be saved and automatically displayed the next time you sign in.

MyTimetable allows you to integrate your timetable with your calendar apps such as Outlook, Google Calendar, Apple Calendar and other calendar apps on your smartphone. Any timetable changes will be automatically synced with your calendar. If you wish, you can also receive an email notification of the change. You can turn notifications on in ‘Settings’ (after login).

For more information, watch the video or go the 'help-page' in MyTimetable. Please note: Joint Degree students Leiden/Delft have to merge their two different timetables into one. This video explains how to do this.

Mode of instruction

By lectures, feedback sessions, using the Nitrogen Footprint model, discussion and self-study. The lectures and the debate at the end of the course are compulsory to attend. It will not be possible to follow the lectures online.

Assessment method

Assignment 1:
Student nitrogen low lifestyle paper. Describe a student nitrogen low lifestylebased on the Nitrogen footprint tool in 2 pages. The 2 pager will be assessed and it weights 25% of the final grade. This assignment will be presented during the first lecture.

Assignment 2:
Stakeholder position paper. Students will individually write a stakeholder position paper with clear arguments supported by facts on how they would see the nitrogen crisis to be solved from the perspective of a stakeholder assigned to them. This assignment is graded and accounts for 50% of the final grade.

Assignment 3:
Stakeholder debate and presentation. In groups of 4-5, students will have a discussion/debate on how to solve the Dutch nitrogen crisis together with all stakeholders. Students will present the outcomes of this stakeholder debate in presentations to the rest of the class. The presentations are graded and account for 25% of the final grade.

The student will pass the course if the overall weighted mark for the three assignments is above 5.5. There will be no exams and it is possible to resubmit a paper that was marked insufficient after one month of the grading of the paper.
