Titre : Iran’s groundwater depletion is reaching crisis levels

ScienceDaily (May 18, 2021)

Résumé
More than three quarters of Iran’s land is under extreme groundwater overdraft, where the rate of human uptake is higher than the rate of natural recharge. Mismanagement by the country’s authorities is exacerbating existing strains on the semi-arid country’s aquifers by an inefficient agriculture industry. Without urgent action, researchers note, the country faces multiple national crises.

Descriptif
The researchers write that mismanagement by the country’s authorities is exacerbating existing strains on the semi-arid country’s aquifers by an inefficient agriculture industry. Without urgent action, they note, the country faces multiple national crises
The authors write that an estimated 74 km3 of groundwater has been depleted from the country’s 500 basins and sub-basins between 2002 and 2015. This has contributed to both growing soil salinity and an increase in land subsidence — basically, land sinking. Among the most at-risk regions of land subsidence is the Salt Lake Basin, which includes Iran’s capital Tehran, home to some 15 million people and already at risk of severe seismic activity.
