Wetlands are crucial ecosystems that are temporarily or permanently covered by water. The aim of this study was to analyse the spatio-temporal changes in wetlands of Thrissur district from 1973 to 2020. Remote sensing and geographical information system were employed for the analysis. Inland wetlands comprise of paddy wetlands, reservoirs, rivers/streams and canals, lakes and ponds/tanks and pits waterlogged due to mining. Coastal wetlands encompass estuaries, backwaters and mangroves. Results of the study revealed a declining trend in total wetland area. Total wetland area reduced from 79,209.50 hectares in 1973 to 46,313.62 hectares in 2020. From 1973 to 2020, total area under inland wetlands decreased from 76,714.73 hectares in 1973 to 56,337.2 hectares, 43,158.96 hectares and 43,059.20 hectares in 1995, 2008 and 2020 respectively. The disappearance of paddy wetlands was the main reason behind the decline in total wetland area, because paddy wetlands constituted more than 70% of total wetland area. The total area under coastal wetlands increased from 2,494.77 hectares in 1973 to 2,711.66 hectares and 3,298.71 hectares in 1995 and 2008 respectively. From 2008 to 2020 coastal wetlands reduced slightly by 44.29 hectares.
