The Forestry and Ecology Department of IIRS established 15 Open Top Chambers (OTC) in September 2022 at Gangotri, Uttarakhand, to delve into the intricate dynamics of Himalayan Alpine Biological Communities under the influence of Experimental Warming. The idea is to test the impact of warming on plant phenology, plant height, biomass and nutrient concentration between OTCs and control plots. Preliminary Continue Reading »

Since the beginning of the industrial era, the anthropogenic carbon dioxide (CO2) concentration has been steadily increasing in the atmosphere caused by deforestation, fossil fuel, biomass burning, cement manufacturing, various land-use practices, and other anthropogenic activities. The ocean absorbs one-third of the total anthropogenic CO2 from the atmosphere and plays an important role in the mitigation of global warming and Continue Reading »

Digital Elevation Models (DEMs) are crucial for studying natural phenomena. Recent research at IIRS has focused on enhancing DEMs through advanced techniques like combining data from Remote Sensing, Satellite Photogrammetry, and SAR Interferometry (InSAR/IfSAR), as well as Spaceborne LiDAR. Notably, studies in the Ghaziabad and Dehradun regions have shown significant improvements in DEMs through fusion methods. Analyzing fused DEMs from Continue Reading »

Submarine ground water discharge (SGD) is a hydrological process of coastal areas in which submarine inflow of fresh and brackish groundwater takes place from land to sea. SGD mainly occurs due to freshwater release from land to sea as base flow as well as overflow through the unconfined aquifer medium. Ground water seeping can occur in the form of submarine Continue Reading »

In Asia, around 45% of biomass burning comes from forest fires, 34% from crop residue/agriculture residue fires (stubble fires), and 20% from grassland & savanna fires. The proportion of biomass burning is highest in China (25%) followed by India (18%). In India, the rice wheat cropping system is the most widely practiced cropping system in Northwest India particularly in Punjab, Continue Reading »
