Abstract
The conversion of Earth’s land surface to urban uses is one of the most irreversible human impacts on the global
biosphere. It drives the loss of farmland, affects local climate, fragments habitats, and threatens biodiversity. Here we
present a meta-analysis of 326 studies that have used remotely sensed images to map urban land conversion. We report a
worldwide observed increase in urban land area of 58,000 km2 from 1970 to 2000. India, China, and Africa have
experienced the highest rates of urban land expansion, and the largest change in total urban extent has occurred in North
America. Across all regions and for all three decades, urban land expansion rates are higher than or equal to urban
population growth rates, suggesting that urban growth is becoming more expansive than compact. Annual growth in
GDP per capita drives approximately half of the observed urban land expansion in China but only moderately affects
urban expansion in India and Africa, where urban land expansion is driven more by urban po
