Synopsis (short abstract) A new version of a digital global map of irrigation areas was developed by combining irrigation statistics for 10 825 sub-national statistical units and geo-spatial information on the location and extent of irrigation schemes. The map shows the percentage of each 5 arc minute by 5 arc minute cell that was equipped for irrigation around the year 2000. This paper describes the data set and the mapping methodology and gives, for the first time, an estimate of the map quality at the scale of countries, world regions and the globe. Two indicators of map quality were developed for this purpose, and the map was compared to irrigated areas as derived from two remote sensing based global land cover inventories.

Irrigation in Africa, Europe and Latin America - Update of the digital global map of irrigation areas to Version 4 2006

Also available in:

No results found.

The first version of the Digital Global Map of Irrigated Areas was published in 1999. It consisted of a raster map with a resolution of 0.5° by 0.5° containing the percentage of the area that was equipped for irrigation around 1995, the so-called irrigation density. For Version 2, updated maps of Latin America, Europe, Africa and Oceania have been published in 2002. With the update to version 3 in 2005 the map for the whole globe was generated by using the same methodology. In the present report, the update to version 4 in 2006 is presented which incorporates improvements for the continents of Africa and Europe and for parts of Latin America as well.

This report describes the Digital Global Map of Irrigated Areas developed for the purpose of global modelling of water use and crop production. The map depicts the percentage of each 0.5˚ by 0.5˚ cell that was equipped for irrigation in 1995. It was derived by combining information from large-scale maps with outlines of irrigated areas (one or more countries per map), FAO data on total irrigated area per country in 1995 and national data on total irrigated area per country, drainage basin or federal state. This documentation describes the dataset, the data and map sources as well as the map generation, and it discusses the data uncertainty.

A Digital Global Map of Irrigated Areas is a publication related to the GMIA version 1. This paper, published on ICID Journal, 49(2), 55-66, describes the dataset, the data and map sources as well as the map generation, and it discusses the data uncertainty. The digital global map of irrigated areas was developed for the purpose of global modeling of water use and crop production, The map depicts the percentage of each 0.5˚ by 0.5˚ cell that was equipped for irrigation in 1995. It was derived by combining information from large-scale maps with outlines of irrigated areas (one or more countries per map), FAO data on totala irrigated area per country in 1995 and national data on total irrigated area per country, drainage basin or federal state.
