The objective of this study is to answer these questions by means of a bibliometric analysis of publications devoted to environmental monitoring platforms integrated into smart cities. Using data retrieved from the Scopus database, this study examines the evolution of scientific output, identifies the most prolific authors, institutions, and countries, and analyzes collaboration networks and dominant research themes through keyword co-occurrence. Particular attention is given to Africa’s scientific visibility and participation in this field. By addressing these questions, the study provides useful insights for several categories of stakeholders. First, it may inform national and international funding bodies seeking to support research at the intersection of environmental sustainability and smart urban technologies. Second, it may help identify scientific institutions with the potential to play a leading role in the development of environmental monitoring systems. Third, it may offer relevant perspectives for companies involved in IoT and embedded technologies by highlighting research trends and opportunities for innovation in smart and sustainable urban environments.

This research aims to address these questions through a bibliometric examination of scholarly work focused on environmental monitoring systems within smart city frameworks. Drawing from Scopus database records, the study tracks how scientific publications have developed over time, pinpoints leading researchers, organizations, and nations in the field, and explores collaborative relationships along with key research topics using keyword analysis. The research pays special attention to how African scholars and institutions contribute to and participate in this area of study. The findings from this investigation offer valuable information for multiple groups of interested parties. Funding organizations at both national and global levels can use these insights when deciding how to allocate resources for research that combines environmental protection with smart city technologies. Academic institutions can benefit by understanding which organizations are positioned to become leaders in creating environmental monitoring solutions. Additionally, businesses working with Internet of Things devices and embedded systems can gain useful perspectives on emerging research directions and potential areas for developing innovative products in environmentally conscious urban settings.
