Urbanization is increasing globally, with over half the world's population now living in urban areas. By 2050, it is projected that 66% of the global population will be urbanized, with Africa and Asia urbanizing the most rapidly at over 1% per year. Population growth, especially in rural areas, is a major driver of urbanization as more people migrate to cities seeking employment, education, and improved standards of living. This rapid urbanization is creating environmental challenges for cities and putting pressure on infrastructure and resources.
