Freshwater use by continents is partly based on several socio-economic development factors, including population, physiographic, and climatic characteristics. Analysis indicates that:

- Annual global freshwater withdrawal has grown from 3,790 km3 (of which consumption accounted for 2,070 km3 or 61%) in 1995, to 4,430 km3 (of which consumption accounted for 2,304 km3 or 52%) in 2000 (Shiklomanov, 1999).

Distribution significant samples of corprate regions from the world

States that collect the most water are those where irrigated agriculture is very important. There are currently 280 million hectares irrigated worldwide, against 190 in 1980. Irrigated agriculture is responsible for 95% of freshwater withdrawals in some developing countries. Looking at the share of renewable resources withdrawn for agriculture, there are clear differences. In some areas, the resource is not mobilized, including where agricultural use is overwhelmingly dominant, either due to low population density or poor management of the resource.

The agricultural sector is by far the biggest user of freshwater. Analysis indicates that: - In the United States, agriculture accounts for some 49% of total freshwater use, with 80% of this volume being used for irrigation (Shiklomanov, 1999). - In Africa and Asia, an estimated 85-90% of all freshwater used is for agriculture (Shiklomanov, 1999). - According to estimates for the year 2000, agriculture accounted for 67% of the world’s total freshwater withdrawal, and 86% of its consumption (UNESCO, 2000).
