The understanding on urban ecosystem dynamic forces is being progressively sensed due to the unparalleled indications rising out of urban expansion. In this study, remote sensing data of Aligarh City, Uttar Pradesh, India from 1990 to 2020 were chosen to obtain the wetland landscape data. Some landscape indices were selected to estimate the changes in landscape configuration within four decades. This study is designed to weigh land cover alterations in and around the wetland ecosystem with high spatial resolution satellite imageries. For the assessment, Normalized Difference Built-up Index (NDBI) and Normalized Difference Water Index (NDWI) were used. The key findings showed that 44.43–70.45% area was transformed in the pan of four decades, which sums up as 26.02% area falls under total changes in built-up area, and 13.86–13.05% of the total wetland was decreased by the built-up area in four decades, which sums up as 0.81% area change. The findings indicated that the water body area dropped, and control of the overall natural wetland decreased. The motives for these outcomes were primarily because of urban expansion. Rendering the present situation of the wetland in Aligarh City, it was recommended that the fortification of the wetland must conjoin with urbanization, which means the wetland should be considered as an imperative portion of the urban landscape.
