Food and Agriculture Organization of the United Nations Land and Water Division AQUASTAT FAOs global information system on water and agriculture by Karen FRENKEN AQUASTAT Programme Coordinator Senior Water Resources Management Officer Second Arab Water Forum, Cairo, 20 November 2011 Improving the flow of water information
Water and agriculture Litres per day per capitaEssentialAbundant Drinking 2 4 Domestic 40 400 Food (evapotranspiration)1 0005 000 Agriculture 70 % Industry 19 % Municipal 11 % Water withdrawal by sector
Some key questions Is there enough water to feed the world in the near future (water balance, competition with other sectors)? What are the performances of the irrigation sector? How do they change with time? How does irrigation contribute to food security and to the achievement of the MDGs and WSSD targets? What is the impact of irrigation on the environment?
Country surveys Dissemination - Web, publications, CD-rom Water resources and irrigation master plans National yearbooks, statistics and reports Expert information Data Country profiles, regional synthesis Spatial data Thematic studies Literature review Critical analysis & data processing – Database management system Standardization Feedback and approval from national authorities/institutions Modeled data – GIS and RS User feedback How information is gathered in AQUASTAT Thematic research Comments provided by experts/institutions
Online country database: 160 variables Geography et population (15), Water resources (45), Water use (30), Irrigation et drainage (60), Environment and health (10) Country profiles and fact sheets: 140 countries Africa, Asia, Latin America and the Caribbean Regional overviews: 5 regions Africa, Western Asia (Middle East), Southern and Eastern Asia, Former Soviet Union, Latin America and the Caribbean Climate information tool Interactive tool to query spatial data-set containing mean monthly climate data Water resources: 200 countries Water resources balance sheets for all countries, containing internal, external and total renewable water resources, considering agreements Water use: 200 countries Irrigated crop calendar, crop water use, irrigation water withdrawal, climate information tool AQUASTAT products
Map on surface water and groundwater irrigation areas Statistical data from > 15 000 administrative units analyzed, standardized and rules applied to determine if area is irrigated by surface water or groundwater Maps, tables and GIS products: wide variety Global, regional and national maps and tables, geo-referenced database on dams, spatial data Country water investment envelop and portfolio: Africa Country surveys on investments related to water for agriculture and energy Institutions: around 300 Addresses and links to institutions in the field of agricultural water resources management, presented by country Glossary: around 300 terms In Arabic, Chinese, English, French, Russian and Spanish Publications: around 25 Around 20 publications AQUASTAT products (cont.)

Irrigated area and land suitable for irrigation in million ha (2001)
Water resources Internal, external surface water and groundwater Country dependency on water from other countries Flows reserved by treaties Calculation spreadsheets with rules and guidelines for accounting water resources Regional overviews of the water resource situation Review of world water resources by country: http://www.fao.org/nr/water/aquastat/water_res/index.stm
Internal renewable water resources in the Nile Basin
Institutions: Addresses and links to around 300 institutions in the field of agricultural water resources management, presented by country Glossary: Definitions for around 300 terms in the field of water resources and agricultural water management, including terminology, origin, comments and typology in English, French, Spanish, Chinese, Arabic, Russian http://www.fao.org/nr/water/aquastat/data/institutions/search.html http://www.fao.org/nr/water/aquastat/data/glossary/search.html?lang=en
Some challenges Sub-national level information Information by river basin Non-availability or unreliability of data for some major indicators Definitions (harmonization) Data linked to reference Validation of data Ways to update and frequency Time series Information dissemination Sustainability of monitoring process in relation to national monitoring capacities If you cant measure, you cant manage… Data is expensive but indispensable
