Abstract: Abstract Understanding how water, food, and energy interact in the form of the water-food-energy (WFE) nexus is essential for sustainable development which advocates enhancing human well-being and poverty reduction. Moreover, the application of the WFE nexus has seen diverse approaches to its implementation in cities across the globe. There is a need to share knowledge in order to improve urban information exchange which focuses on the WFE nexus’ application and impacts on the United Nations (UN) Sustainable Development Goals. In this study, Natural Language Processing (NLP) and Affinity Propagation Algorithm (APA) are employed to explore and assess the application of the WFE nexus first on a regional basis and then on the city level. The results show that after the exhaustive search of a database containing 32,736 case studies focusing on 2,233 cities, African and Latin American cities have the most potential to encounter resource shortages (i.e., WFE limitation) and are systematically underrepresented in literature. In addition, the study shows that Southern hemisphere cities can benefit from knowledge transfer because of their limited urban intelligence programmes. Hence, with regional and topic bias, there is a potential for more mutual learning links between cities that can increase WFE nexus policy exchange between the Northern and Southern hemispheres through the bottom-up case-study knowledge.
