Global Cities: Defined by their Total Population in Relation to Major Capital Cities

The rapid growth of urban populations has become a pressing issue globally, with many cities struggling to provide adequate access to safe drinking water and sanitation facilities for their residents. According to the UN-Water factsheet on water and urbanization, between 1990 and 2010, while 813 million people gained access to improved sanitation and 1.089 billion people gained access to improved drinking water, the urban population grew by a staggering 1.089 billion people.

One of the most significant challenges facing global cities is the lack of adequate water and sanitation facilities. This has resulted in numerous health issues such as diarrhoea, malaria, and cholera outbreaks. The consequences of these problems are far-reaching, affecting not only human health but also safety, the environment, economic growth, and development.

The unsustainable nature of urban settlements is further exacerbated by the increasing frequency of water-related disasters such as floods and droughts. These events have devastating impacts on cities, causing widespread destruction and displacement of people. The provision of adequate water and sanitation facilities has become a pressing issue in many global cities, with the exploding urban population growth creating unprecedented challenges.

The developing world is experiencing the most rapid urbanization rates, with cities gaining an average of 5 million residents every month. This rapid growth is putting immense pressure on city infrastructure, including water and sanitation systems. In fact, it is estimated that by 2030, nearly 60% of the world's population will be living in cities.

In conclusion, global cities are defined by their total population in relation to major capital cities, and their ability to provide adequate access to safe drinking water and sanitation facilities is a critical factor in determining their sustainability. The rapid growth of urban populations presents numerous challenges for cities, including the provision of essential services such as water and sanitation. It is imperative that global cities prioritize the development of sustainable water management systems to ensure the health, safety, and well-being of their residents.
