    Disambiguation of water use statistics 2010

    Water statistics at all levels are crucial for sustainable development and management. They shape policy, decision-making, and act as a proxy for development. Integrated Water Resources Management plans around basic information on water resources and use. Unfortunately, the nomenclature surrounding water information is often confusing and gives rise to different interpretations and thus confusion. When discussing the way in which renewable water resources are utilized, the terms water use, withdrawal, consumption, abstraction, extraction, utilization, supply and demand are often used without clearly stating what is meant. This note attempts to shed light on how the AQUASTAT programme defines these terms, although readers should be aware that these definitions are not globally standardized. Harmonization efforts within the UN system are ongoing.

    AQUASTAT - Désambiguïsation des statistiques de l'eau 2012
    Also available in:

    Les statistiques relatives à l’eau jouent, à tous les niveaux, un rôle crucial pour le développement durable et la gestion à long terme de cette ressource : elles orientent les politiques et la prise de décision et servent d’indicateur indirect pour le développement tandis que la gestion intégrée des ressources en eau se planifie sur la base d’informations essentielles concernant ces ressources et leur utilisation. Malheureusement , la nomenclature relative à l’information sur l’eau prête souvent à confusion car elle donne lieu à différentes interprétations. Lorsque l’on étudie les modes d’utilisation des ressources en eau renouvelables, les termes consommation , usage , prélèvement , dérivation , extraction , utilisation , approvisionnement et demand e s’emploient souvent sans définir clairement ce qu’ils signifient. La présente note tente d’éclaircir la façon dont le p rogramme AQUASTAT définit ces termes. Le lecteur notera c ependant que ces définitions n’ont pas été uniformisées à l’échelle mondiale, des efforts d’harmonisation étant menés actuellement au sein du système des Nations Unies .

    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.
