The NISAR (NASA-ISRO Synthetic Aperture Radar) mission is a pioneering path breaking satellite mission developed as a collaboration between ISRO and NASA for developing crucial understanding of the earth and its dynamism. A collaborative scientific mission of ISRO and NASA, NISAR has two active microwave sensors in two bands viz. L-band and S-band, also known as Synthetic Aperture Radar (SAR). Continue Reading »

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 »
