Deepor Beel is one of the most substantial wetlands in Assam as well as a Ramsar conceded site (2002) functions as a sponge to recharge and replenish the groundwater table. Deepor Beel is like a boon to a floodprone (natural and urban induced) area like Assam. It had been noticed that the areas surrounding it possess additional potential area characteristics. GMDA (Guwahati Municipal Development Authority) had declared and categorized those under green zones and eco-sensitive zones. In this work, an attempt has been taken to discern the authentic amount of urban encroachment, its extent, and pattern over the last four decades namely 1995, 2001, 2009, 2019 using LULC (land Use Land Cover Maps). However, it has been noticed that the actual overall encroachment over the demarcated eco-sensitive and green zones was much higher than the area designated by the authorities due to rising and unprecedented urban intrusion.
