    This document was prepared for the Sixth Water Information Summit, Delft (WIS6), The Netherlands, 9-12 September 2003. It describes the AQUASTAT information system, which consists mainly of: a) systematic descriptions of the state of agricultural water management by country; b) up-to-date online data by country; c) digital geographical data on water resources and irrigation; d) specific thematic studies. Its experience indicates the importance of systematic data and information collection and evaluation, harmonized definitions and classifications, associated metadata, support for evaluation in the database management system, website properties to guarantee quick and good access for all users, and collaboration with other institutes.

    AQUASTAT - Irrigation water requirement and water withdrawal by country
    FAO AQUASTAT Reports
    2012
    Also available in:

    Agriculture, and especially irrigated agriculture, is the sector with by far the largest consumptive water use and water withdrawal. To estimate the pressure of irrigation on the available water resources AQUASTAT, FAO’s global information system on water and agriculture, has undertaken a major review of irrigation water requirement and water withdrawal for irrigation for 167 countries. Detailed irrigated crop calendars have been prepared by country. The improved methodology used has made it possible to show additional variables in the AQUASTAT database: water withdrawal for irrigation, irrigation water requirement, as well as harvested irrigated crop areas. Regional and country tables have been prepared on areas equipped for irrigation, actually irrigated areas, irrigated harvested crop areas, with special attention to irrigated cereals, and irrigated fodder and pasture, as well as water requirement ratios or irrigation efficiencies. The AQUASTAT database provides policy- and decisions-makers as well as the scientific community with a complete dataset containing reliable data, calculated in a uniform way, and comparable with each other at country level.

    AQUASTAT - Understanding AQUASTAT, FAO's global water information system 2014

    This information note covers a twenty year history of the collection and analysis of water-related data and its dissemina - tion as an international public good, freely available to all. The main country database on water resources and their use—itself a major challenge to present in uniform terms—provides the platform for organizing and presenting over 180 variables and indicators that can be searched and extracted for all countries and for dierent regions over an extensive time period. The process of collecting and checking the data has resulted in the establishment of a unique network of collaborators who provide data, use data from other countries for comparative purposes, and exchange views and expe - riences on how best to measure and account for water-related use. Users range from international private companies to non-governmental organizations, and virtually all signicant reports related to water depend on the data provided by AQUASTAT. New technologies will improve data availability and provide new routes for users to obtain data, but the structure and experience underlying AQUASTAT will certainly remain central and basic to organizing those data and ensuring free international distribution.
