Deosai National Park - Diachronic Analysis of Water bodies and Wetlands

In this map, the extraction of lakes and wetlands from the time-series analysis of Landsat imagery returned. Four maps, referred to the four years 1990, 259 1000, 2009 and 2018 have been created to show the geographic distribution of the lakes a 260 and wetlands in the different time. It can be seen that 66 lakes can be considered permanent in the range of the considered forty years, as they were present in each of the 13 images from 1990 to 2019. Moreover, in the maps, the number of lakes in the year of ref- 263 erence are displayed: 203 in 1990, 139 in 2000, 190 in 2009, and 175 in 2018. The number and surfaces of the lakes have been analysed in the GIS environment extracting the following information:

• 66 lakes are permanent from 1990;

• The number and the total surface of the small lakes show a gentle decrease from 1990 toward 2019;

• The surface of the wetlands shows a clear increasing in the considered interval.
