With increasing anthropogenic activities and the escalating impacts of climate change, flood hazards have become more frequent and severe, causing extensive damage to crops, settlements, and infrastructure. Flood hydrologists have long faced challenges in accurately estimating flood depths-an essential parameter for effective disaster response and risk mitigation. Although optical and microwave satellite imagery have significantly advanced flood mapping by providing Continue Reading »

Authors- Manu Mehta and Raghavendra Pratap Singh An exoplanet, short for extrasolar planet, is a planet that orbits a star outside our solar system. These planets follow the same physical laws - orbiting stars and varying widely in size and composition. When you look up at the night sky and see countless stars, it's amazing to think that many of Continue Reading »

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 »

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 »
