Between 41° and 56° South latitude, the absolute glacier area loss was 5450 km2  in the last approximately 150 years, with an annual area reduction increase of 0.25% yr-1 for the period 2005- 2016 . The small glaciers in the northern part of the Northern Patagonian Ice Field had over all periods the highest rates of 0.92% a-1. In this sub-region, increased melting of ice is leading to changes in the structure and functioning of river ecosystems and in freshwater inputs to coastal marine ecosystems  . In addition, in the case of coastal areas, the importance of tides and rising sea levels in the behaviour of river floods has been demonstrated .
