From rising consumption to urban water deficit, the drivers illustrate the major challenges and opportunities we face.

Rapid population growth is dramatically increasing global demand for water. How much water do you waste? What if a 100-year storm happened yearly? What happens if the rains stop coming? The Drivers of Change Water cards examine the top 25 drivers of change impacting the demand, supply and use of water across the world.

Is your city too thirsty?

The percentage of the global population living in urban areas is expected to reach 66% by 2050. A review of the world’s developing regions reveals that Africa and Asia are the two regions suffering most from lack of urban water supply and sanitation. Major concerns include over-exploitation and pollution of water sources.

The global population reached 7 billion in 2011 and is projected to reach 9 billion by 2050. Growth is driven by increasing life expectancy and a rise in the number of women surviving to reproductive age, particularly in developing Africa and Asia. As populations expand, demand for water will increase dramatically. This will be driven primarily by a growing demand for food – which is expected to increase by 70% by 2050 – and associated agricultural water use, expected to increase by at least 19% by 2050. The Drivers of Change Water cards examine the major drivers changing the demand and supply of water across the world.
