With the successful launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission on 30th July 2025 from ISRO Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, a new era of SAR dual/multi-frequency SAR missions has begun. NISAR is a jointly developed SAR mission with L-Band (24 cm wavelength) developed by NASA and S-band (9.4 cm wavelength) developed by ISRO. The most Continue Reading »

Authors: C.M. Bhatt, Pankaj R Dhote, Nishant Rana & Abhay Masiwal The Indo-Gangetic Plains are among the most chronically flood-affected regions in India. The area receives a substantial amount of rainfall during the monsoon season (June–September), which leads to increased river discharge and frequent flooding. Flooding in the Ganga floodplains is a recurrent phenomenon (Bhatt et al.,2016). In July 2025, Continue Reading »

Shifting cultivation, a traditional agricultural practice, has long influenced forest cover dynamics across Southeast Asia. This cyclical process of vegetation clearance, burning, and regrowth carries substantial environmental and socio-economic consequences. In India, shifting cultivation—locally known as jhum—is prevalent in the northeastern states, including Tripura. Over time, socio-economic changes and policy interventions have altered traditional jhum cycles, influencing land use patterns. Continue Reading »

Authors- Ashutosh Bhardwaj, Hari Shankar Srivastava and Raghavendra Pratap Singh Spaceborne LiDAR datasets are contributing immensely for the topographic, ice mass-balance and vegetation related studies. It provides a global view of changes occurring in elevation over Earth. CartoDEM Version 3 Release 1 openly accessible datasets are currently the most reliable datasets for the relatively plain regions in India. The study Continue Reading »

*Synthesized image for representation purpose only. Vegetation photosynthetic activity, the fundamental process by which plants convert light energy into chemical energy by fixing atmospheric carbon dioxide, is critical for the global carbon cycle, ecosystem productivity, and climate regulation. It varies greatly depending on the type of ecosystem (e.g., forest, grassland, cropland), plant species, and environmental conditions. Traditional vegetation indices (like Continue Reading »
