Supporting water accounting methodologies and frameworks through the Spatial Data and Knowledge gateway Project (IWMIDSP)

IWMIDSP ( ) is an award winning pathfinder pioneered by IWMI for providing state-of-the-art global public good (GPG) spatial data on water and land resources for river basins, nations, regions, and the world (MTP 1: 2004-2006, modeling/Remote Sensing tool milestones). The Environmental System Research Institute (ESRI) recognized IWMIDSP with a Special Achievement in GIS (SAG) Award at the 27th Annual ESRI International User Conference in San Diego, California, June 20, 2007. In the ESRI press release, they state IWMI “…. stood out from more than 300,000 organizations worldwide that use geographic information system (GIS) software to make a difference in the world….” (Annex 1).

Released to the public in June 2004, currently IWMIDSP has 3500+ registered users from 80+ countries. Monthly users average about 1500+. The 2007 IWMIDSP annual survey showed 80% of its data used for research purposes and 70% of the respondents rate it 7 or higher in scale of 1 to 10. The IWMIDSP is profiled by: (a) Water Monitoring Alliance, (b) UN-Water Africa\UN Economic Commission for Africa; and (c) World Health Organization: Health and Environmental Linkages Initiative.

Surveys and regular feedback indicate that the IWMIDSP data is widely used throughout the world. Some examples of applications include (Annexes 2 & 3):
