“…The sudden increase in rainfall can be one of the causes of flash floods (Jha et al 2021,Bharath andVenkatesh 2022). In conformity with prior studies, the majority of agricultural and fallow land was inundated in the coastal districts as a result of the Amphan (Behra et al 2021, Kumar et al 2021a and crops were damaged (~66 %) in Odisha, West Bengal, and the western coast of Bangladesh (Ahammed and Pandey 2021). The damage to vegetation poses severe consequences on the ecosystem and ecosystem services and affects socioeconomic composition (Zommers et al 2016).…”

Evaluation of a natural disaster's impact is essential for formulating preparedness, mitigation, and response plans. This study evaluates the impact of super cyclone Amphan, which hit the Indian Sundarban Biosphere Reserve on May 20, 2020. Pre-and post-cyclone land use/land cover (LULC) maps were created using LANDSAT 8 OLI, while flood inundation was mapped using Google Earth Engine (GEE) cloud platform and Sentinel-1 A C band Synthetic Aperture Radar (SAR). The study revealed that tropical cyclone Amphan had a significant impact on dense/mangrove vegetation (5%) and agricultural (2%), as well as an increase in flooded areas (40%). The proximity of 3% (290.62 km ) of the area near the path of the cyclone was impacted by flooding, particularly in low elevation areas (5m). The investigation observed that 2 cyclone Amphan caused extensive damage to open vegetation, agricultural lands, and urban areas. These findings provide a quantifiable estimate of cyclone Amphan's damage and will help decision-makers improve disaster preparedness. Native-based intervention initiatives, including natural ecosystem-based disaster risk reduction strategies, can be implemented to promote and conserve mangroves, rehabilitate human populations from highly vulnerable areas to safer areas, and ensure their livelihood security in cyclone-prone regions.

“…The North 24 Parganas district is generally impacted by natural disasters and environmental degradation every year, e.g., the Odisha super cyclone (1999), Phyan (2009), Nilam (2012), Phailin (2013), Helen (2013), Hudhud (2014), Vardah (2016), Ockhi (2017), Titli (2018), Fani (2019), Bulbul (2019), Amphan (2020) and Yass (2021). Many cyclones and floods have been associated with extreme climate events [28][29][30][31]. Many cyclone events have occurred like, Aila, Fani, Bulbul, Amphan, and Yash.…”

Delineating the Crop-Land Dynamic due to Extreme Environment Using Landsat Datasets: A Case Study

et al. 2022

Extreme climatic conditions and natural hazard-related phenomenon have been affecting coastal regions and riverine areas. Floods, cyclones, and climate change phenomena have hammered the natural environment and increased the land dynamic, socio-economic vulnerability, and food scarcity. Saltwater intrusion has also triggered cropland vulnerability and, therefore, increased the area of inland brackish water fishery. The cropland area has decreased due to low soil fertility; around 252.06 km2 of cropland area has been lost, and 326.58 km2 of water bodies or inland fishery area has been added in just thirty years in the selected blocks of the North 24 Parganas district, West Bengal, India. After saltwater intrusion, soil fertility appears to have been decreased and crop production has been greatly reduced. The cropland areas were 586.52 km2 (1990), 419.92 km2 (2000), 361.67 km2 (2010) and 334.46 km2 (2020). Gradually the water body areas were increased 156.21 km2 (1990), 328.15 km2 (2000), 397.77 km2 (2010) and 482.78 km2 (2020). The vegetated land area also decreased due to it being converted into inland fishery areas, and around 79.15 km2 were degraded during the last thirty years. The super cyclone Aila, along with other super cyclones and other environmental stresses, like water-logging, soil salinity, and irrigation water scarcity were the reasons for the development of the new fishery areas in the selected blocks. There is a need for proper planning for sustainable development of this area.
