Beware: Our gravity is changing!
Explore how Earth’s gravity is shaped by hydrology. On July 01 at 14:00, Alka Singh from the Amrita University in India explains how suites of satellites provide us a bird's eye view on hydrological processes.
ZARM Talk by Alka Singh

- Location: ZARM, room 1730
Explore how Earth’s gravity is shaped by hydrology and how suits of satellites provide us a bird eye view. Understand how spatio-temporal variation of climatic variables and anthropogenic changes has long-term implications on our hydrological processes. We will diagnose how water-energy-food nexus are connected to the sustainable groundwater management. India epitomizes the urgency of sustainable management with rapid urbanization, a population exceeding 1.4 billion, intensifying climate variability, and resource-intensive agriculture, heightening stresses on water, food, and energy systems. We will take a glimpse of the role of remote sensing and artificial intelligence (AI) in achieving United Nations sustainable development goals (SDG) focusing on SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), SDG 7 (Affordable and Clean Energy), and SDG 13 (Climate Action). The talk will comprehend potential, challenge, scope and future prospects of spaceborne earth’s hydrological monitoring, with its need to be complemented by ground based geophysical surveys, physics and AI informed model, and local-regional-global scale understanding.
Dr. Alka Singh currently serves as an Assistant Professor (SLG) at the Amrita Center for Wireless Networks & Applications (Amrita WNA), Amritapuri Kerala. Her area of expertise is in remote sensing of hydrology. She is interested in solving Earth Science-related problems with a holistic and sustainable approach.
