Regionalization refers to the process of dividing a larger geographic area into smaller regions based on shared characteristics such as socio-economic factors, culture, ecology, or political boundaries. This research area is important for understanding the unique characteristics and challenges of different regions, as well as for developing targeted policies and strategies to address regional issues. Regionalization can be applied to various fields such as economics, public administration, urban planning, environmental studies, and political science. Researchers in this area may use a variety of methodologies such as geographic information systems (GIS), statistical analysis, and qualitative research methods to analyze regional data and trends. Ultimately, regionalization aims to promote sustainable development, improve governance, and enhance the quality of life within specific regions.
