Northern Italy's water crisis threatens irrigation as main river dries

Northern Italy faces a critical water shortage as reserves deplete at an accelerating pace, according to The Local Italy. The region's main river—the Po, which supplies much of the north's irrigation infrastructure—has fallen to dangerously low levels, forcing farmers and local authorities to confront the reality of sustained drought. The warning comes as the July heatwave continues to grip the peninsula, intensifying evaporation and deepening the crisis for agriculture across Piedmont, Lombardy, and the Veneto.

For Liguria, the implications extend beyond the region's borders. The Ligurian coast depends on agricultural produce from the Po Valley and the wider northern plain; disruption to irrigation there ripples through supply chains that feed the Riviera's tourism sector and regional food economy. More immediately, the drought threatens hydroelectric generation at Alpine facilities that supply power to the northwest, including Liguria. Local officials have begun rationing water allocations, signalling that the crisis is not transient but structural, driven by the combination of heat stress and depleted winter snowpack.

The scale of the threat is underscored by the timing: summer has barely peaked, and forecasters have warned of sustained heat through July and beyond. The Po's low flow has already prompted restrictions on agricultural water use, and further deterioration could force farmers to abandon crops or shift to lower-value alternatives. For a region that exports produce across Italy and Europe, the economic consequences extend far beyond the farm gate. Genoa's port, which handles agricultural exports, faces potential disruption to supply chains that depend on timely harvests from the north.
