World freshwater resources

The CD-ROM consists of 4 parts. The first part contains an extended summary of the monograph "World water resources at the beginning of the XXIst century" and basic research results supplied with appropriate figures, graphs and tables. The second part contains tables and graphs of variations (for the same long-term period from 1921 up to 1985) of renewable water resources by years, these water resources distribution during a year by continents, physiographic and economic regions, selected river basins and individual countries; the dynamics of river water inflow to each ocean and to the world ocean by latitudinal zones are given. The third part contains data on water use for the needs of population, industries, agriculture (total water withdrawal and water consumption), as well as water losses for additional evaporation from reservoirs during the present century (1900, 1940, 1950, 1960, 1970, 1980, 1990 and 1995) and for the future (2000, 2010, and 2025) for all physiographic and economic regions and continents. Water use in dynamics for selected countries is demonstrated from 1950 up to 1995 and for the future. Moreover, the values of water use published in basic international and national sources are given for comparison. The dynamics of water availability (per capita) are given for the period from 1950 up to 2025 for all physiographic and economic regions and selected countries. The fourth part presents observation data on monthly and annual river runoff from major stations (more than 2000 hydrological stations) located in different countries in each continent. These data have been taken from different sources (from the GRDC, from publications of UNESCO and other international organizations, from the archives of the State Hydrological Institute, from national sources, including data on special requests) and have been used for the assessment of the dynamics of renewable water resources on the global scale and fresh water inflow to the World oceans.
