About the speaker

Dr. Koyel Sur is a Scientist at the Punjab Remote Sensing Centre, specialising in geospatial science, remote sensing and GIS. Her work integrates Earth observation, machine learning and AI for environmental monitoring, flood mapping, soil erosion modelling, land-use dynamics and climate-risk assessment. She has authored more than 50 international journal papers and received the National Geospatial Award from IIT Bombay.

About the talk

Wetlands act as natural buffers against floods and climate extremes. They regulate hydrology, store excess water, reduce erosion and support biodiversity and food security. The talk explored how remote sensing, GIS and AI can assess wetland ecosystem services, identify vulnerable systems and support evidence-based disaster risk reduction, conservation and restoration, through three steps: observe wetland change with Earth observation, understand it by combining geospatial data, GIS and AI-driven assessment, and build resilience through risk reduction, protection and ecological restoration.

What was covered

  • Wetland ecosystem services, and the growing disaster risks from extreme rainfall, encroachment, urban expansion and drainage alteration.
  • Satellite remote sensing and GIS for mapping wetland extent, hydrological dynamics, vegetation and ecosystem health, water quality, climate change effects, disaster risk reduction and habitat mapping.
  • The Harike wetland in Punjab, a Ramsar site at the confluence of the Beas and Satluj, its catchment drainage and canal network, vegetation diversity mapping from field spectral measurements and machine-learning classification, and about 30 years of surface-water mapping.
  • An extended question-and-answer session with fourteen questions on carbon credits, wetland classification, LiDAR and elevation data, flood vulnerability, restoration, digital twins, groundwater interaction, open data sources such as Sentinel-2, Google Earth Engine and Bhuvan, and monitoring frequency.
