Abstract

Worldwide urban areas are losing the wetlands without any record of their location and spatial extent. Recording the status of wetlands is required urgently in the present scenario of climate change and environmental degradation. In this context, the present study has been carried in Ranchi Municipal Corporation (RMC) area to analyze the distribution and status of wetlands in two different periods i.e. in the year 2005 and year 2018 using high resolution satellite data. The study reveals that in the year 2018 a total of 21 lakes and ponds vanished losing 5.1 ha area to built-up area in 18 wards and 12 lakes and ponds dried-up losing 1.2 ha area in 10 wards. The study suggests the census of urban wetlands at the national level. Key Words: high resolution data, urbanization, lakes and ponds, waterlogged, wetland census
