Synopsis (short abstract) One of the first products developed by AQUASTAT, since its start in 1994, has been the water resources assessment methodology. Even though very useful, during the 20 years that AQUASTAT has been using this methodology it appeared that the methodology is not without shortcomingsand is in some cases overcomplicated. It has become increasingly apparent that some of the main problems should be addressed. Therefore, in March 2015 AQUASTAT has implemented som e changes, which are described in this note.

    AQUASTAT - Understanding AQUASTAT, FAO's global water information system 2014
    Also available in:
    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.

    Key water resources statistics in AQUASTAT
    FAO’s Global Information System on Water and Agriculture

    This article describes the methodology used by AQUASTAT to assess natural and actual freshwater resources for the world by country. It deals with renewable water resources and concentrates mainly on the physical assessment of internal and external resources. It presents a picture of the state of the world’s water resources that is not only the natural state but also the current situation, taking into account existing uses of water and their implications for countries sharing river basins. Much remains to be done in order to obtain sound statistics on water resources, and particularly standardized data sets, at global level. This article presents some reflections in this sense. Submitted for IWG-Env, International Work Session on Water Statistics, Vienna, June 20-22 2005.

    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.
