Freshwater is a critical resource, whose deficiency will very soon become a key factor governing the development of civilization. In terms of the current and anticipated demand, the available freshwater amount on the earth is limited, especially, if the ongoing environmental pollution is taken into account. The presented estimates of renewable fresh groundwater resources and the potential water availability give an insight into the distribution of water resources and their use in different countries and continents. The obtained results allowed the authors to evaluate groundwater resources on the regional and global scale, compare them with surface water resources, and refine the present-day groundwater availability per 1 km2 and per capita in different countries of the world. The per capita water availability on the earth was shown to have halved from 1970 to 2003--2005. The present-day and anticipated water consumption in the world and individual countries is considered.
