(220812) -- MANTOVA (ITALY), Aug. 12, 2022 (Xinhua) -- Photo taken on Aug. 12, 2022 shows low water levels of the Po River in Mantova, Lombardy region, Italy. More than 200 major Alpine glaciers have disappeared in Italy since record-keeping began in 1895, Italy's environmental lobby group Legambiente said in a report released on Aug. 10, 2022. The lack of fresh water coming from glacial reserves is a major contributor to the drought gripping most of Italy and threatening to reduce agricultural output, especially in northern Italy, where water from glaciers is a key part of the area's ecosystem, noted the report.
