The MAR Portal (marportal.un-igrac.org) contains detailed information on managed aquifer recharge (MAR) sites around the world. The IAH MAR commission aims to facilitate research on MAR by creating an overview of MAR sites globally. New MAR sites and suitability maps will be uploaded to the portal as they come available. If you have data on MAR sites that should be included in the database, or if you have updated information on MAR sites, please get in touch and help us to improve access to information on MAR sites.
Please contribute to the global MAR inventory by sharing details on MAR sites. You can use the web form below. Data will be reviewed and included into the MAR portal.
