National Glaciers Within the last three decades, glaciers of Bhutan shrank by 189sqkm, less than half the size of one of the country’s smallest dzongkhags, Pemagatshel.

It is a fall by 7.3 percent, compared with 860sqkm in 1980, which, when recorded in 2010, dropped to 671sqkm.

Going by a recent study on decadal change of glacier in Bhutan that the international centre for integrated mountain development (ICIMOD) conducted, the melting of glacier led to a growing number of smaller glaciers by 2.9 percent.
