The coastal zone represents a unique interface between land and sea, addressing the ecological crisis it faces is of global significance. One most fundamental effective measures to extract coastline’s location on large scale, dynamically, accurately. Remote sensing technology has been widely employed in coastline extraction due its temporal, spatial, sensor diversity advantages. Substantial progress made with diversifying data types information methods. This paper focuses discussing research related sources methods for remote sensing-based extraction. We summarize suitability some algorithms several specific types, including rocky coastlines, sandy muddy biological artificial coastlines. also discuss significant challenges prospects dataset construction, remotely sensed selection, applicability method. In particular, we propose idea extracting coastlines based scene knowledge map (CSKG) semantic segmentation review serves as comprehensive reference future development pertaining exploitation management.

Abstract Current widespread and intensive soil degradation in India has been driven by unprecedented levels of population growth, large‐scale industrialization, high‐yield agriculture, urban sprawl the spread human infrastructure. The damage caused to managed natural systems threatens livelihoods local services leads national socio‐economic disruption. Human‐induced results from land clearing deforestation, inappropriate agricultural practices, improper management industrial effluents wastes, careless forests, surface mining, sprawl, ill‐planned commercial development. Of these, including excessive tillage use heavy machinery, over‐grazing, unbalanced inorganic fertilizers, poor irrigation water techniques, pesticide overuse, inadequate crop residue and/or organic carbon inputs, cycle planning, account for nearly 40% (121 Mha) across India. Globally, activities related agriculture contribute transgression four nine Planetary Boundaries proposed Rockström et al.

The east coast of India, especially the coastal region Odisha, is highly threatened by tropical cyclones. This study develops a detailed risk map for cyclones in districts Odisha at micro level, focusing on assessment factors block level. Using multi-criteria decision making (MCDM) approach, considers four primary components: Exposure, vulnerability, susceptibility, and mitigation options. Explainable Artificial Intelligence (XAI) framework, which uses XGBoost model conjunction with SHAP values, applied to identify elucidate influencing levels 69 blocks. Results indicate that about 65% area high cyclone, northeastern central regions. In particular, 32 blocks are classified as very high-risk zones. shows contrast levels, northeast southeast higher risk, while southern regions such Ganjam Puri parts Kendrapara Baleswar lower risk. findings from this crucial local authorities vulnerable areas improve cyclone preparedness management strategies Odisha.

The Northern Indian Ocean (NIO) is one of the most vulnerable coasts to tropical cyclones (TCs) and frequently threatened by global climate change. In year 2020, two severe formed in NIO devastated subcontinent. Super cyclone Amphan, which Bay Bengal (BOB) on 15 May made landfall along West coast with a wind speed above 85 knots (155 km/h). Nisarga Arabian Sea (ARS) 1 June 2020 Maharashtra 60 (115 present study has characterized both TCs employing past cyclonic events (1982–2020), satellite-derived sea surface temperature (SST), direction, rainfall dataset, regional elevation. Long-term occurrences revealed that encountered higher number each than ARS. Both had different intensities when making landfall; however, elevation played significant role controlling associated hazards. mountain topography east weakened wind, while deltas west no control over wind. 30 (56 km/h) within 6 h from landfall, Amphan took 24 weaken We analyzed precipitation patterns during concluded much more (1563 mm) (684 mm). Furthermore, impact land use cover (LULC) was examined relation field. field damaged 363,837 km2 land, whereas affected 167,230 land.
