in this research, I study the Nitrogen Crisis by comparing Twitter content to real-life events, answering the following research question: How does the intensity of emotions and discussed topics on social media relate to the characteristics of real-life demonstrations during a sustainability policy crisis? To characterise online events, sentiment analysis and topic modelling are applied to analyse tweets about the nitrogen crisis to paint a picture of what subjects were discussed online, and how people are feeling about them. To characterise offline events, a codebook is developed with categories that reveal information on the scale, intensity and extremism during real-life demonstrations. The most promising finding is that topic models with higher numbers of topics but lower coherence scores prove to be more interesting sources of information on underlying topics and trends on Twitter.
