As populations and markets grow worldwide, cities are expanding at unprecedented rates. More than half of the world's population now lives in urban areas. Populations residing in cities consume higher amounts of water, energy, food, and land than their rural counterparts, and are more vulnerable to extreme climate hazards.
Urbanization contributes to increases in greenhouse gas emissions and widespread wild area loss across the world.
