Impact of Global Population Growth

The world population is projected to grow from 6 billion in 1999 to 9 billion by 2045. As it stands today, the world's water and energy supplies are not in a position to support such a large global population, especially as this population becomes increasingly urban.

For the first time in history, more than 50 percent of the world's population lives in an urban area. By 2050, 70 percent of the world's population will be living in towns and cities. (Source: Bulletin of the World Health Organization)

By 2030 the towns and cities of the developing world will make up an estimated 81 percent of urban humanity. Today, however, only about half of urban dwellers in developing countries have water connections in their homes. (Source: UNFPA)

Also of importance is the geographic distribution of the growing population.

  • Specifically, 39 percent of the world's population lives within 100 kilometres of a coast, where fresh water isn't always readily available. 
  • In fact, 42 of the 70 cities with more than 1 million inhabitants are located on a coast and do not have direct access to additional fresh water resources.
