IWMI-CPWF have released an on-line data and information portal that provides access to water, agriculture and environment scientific data
The portal name is IDIS - Integrated Database Information System. It allows you to query, download, plot, graph shared data and access its metadata (in GeoNetwork of course – quite a few CGIAR centers have tried to build a similar multi-domain data sharing portal but none succeeded so far – this is a CGIAR breakthrough.
