N2  - Climate change makes rubber plantations in different regions of Kerala vulnerable to floods. Kerala experienced a massive flood in 2018, which caused landslides, loss of lives and property, agricultural losses, etc. During 2019 and 2020, the floods repeatedly affected the state. In Kerala, rubber plantations cover about 15 percent of the state’s geographical area, which represents 22 percent of the total cultivated area. Appropriate agricultural management practices can help mitigate flood risks and impacts in rubber plantations in Kerala; therefore, it is extremely important to develop measures to reduce the impact of flooding. Using remote sensing and Geographic Information System (GIS), spatial information of rubber area from Sentinel-2 satellite data and flood plains in Kerala were analyzed and the extent of rubber area in flood plains at panchayat level was estimated. Based on the results, good agricultural practices and WebGIS interfaces are developed to reduce and mitigate flood risk in rubber plantations. About 49237 ha of rubber area in the state are at risk of flooding, representing 8.4 per cent of rubber cultivation in the state. Districtwise analysis shows Ernakulam (9942 ha), Malappuram (7221 ha), Kottayam (5827 ha), Palakkad (5232 ha) and Kollam (4542 ha) had the highest area under rubber in the flood plains. In comparison, districts such as Wayanad (177 ha), Kozhikode (967 ha), and Alappuzha (1031 ha) had less rubber area in flood plains. A total of 64 rubber growing panchayats are located in the floodplains of Ernakulam. Likewise, 61 rubber growing panchayats are located in Malappuram, 59 in Kottayam, 73 in Palakkad and 55 in Kollam. The site-specific information can be used to reduce flood risks in rubber growing areas in Kerala using district and panchayatwise GIS datasets for rubber areas in floodplains. Rubber farmers can adopt good agricultural practices where rubber growing areas are located in flood plains using the panchayat-level flood risk maps. GIS datasets of rubber areas in flood plains were integrated into IoT platforms such as Web GIS and Android apps, making the results of this study useful for rubber growers
