Po River Dries Up

The Po River, the longest river in Italy, is hitting record low water levels after months without heavy rainfall. This Copernicus Sentinel-2 animation shows a part of the Po Valley, near Piacenza, and reveals how the river has significantly shrunk between June 2020 and June 2022.

Stretching from the Alps in the northwest to the Adriatic Sea on the east coast, the vast waterway is a vital source of water for several regions. It is used for drinking water, nourishing vast swathes of agricultural land, as well as producing hydroelectric power across northern Italy.

Water in the Po Valley has now dropped to record-low levels, partly as a result of the lack of rainfall that northern Italy has been suffering, as well as high temperatures and a lack of snow in the mountains that feed the river. Many of these areas have now been without any rain at all for more than 110 days, according to the Po River Observatory.

The Po River is normally a wide stretch of murky water (as seen in the June 2020 acquisition) but has now dried up with large expanses of sand exposed (as seen in the June 2022 acquisition).

The Po Valley is the most important agricultural area in the country, as it produces around 40% of Italy’s food including wheat, rice and tomatoes. With the ongoing drought, farmers are struggling to keep crops irrigated and many towns in the Po Valley have been asked to ration water during the night amidst the drought.
