It’s nice to meet you!
I’m Pratistha Katwal from Nepal 🇳🇵. I hold a degree in Environmental Science and have a passion for working with data—whether it’s geospatial datasets, satellite imagery, or survey responses.
📍 Household-Level Flood Risk Assessment @ NAXA Pvt. Ltd.
As a Former Research Associate, I contributed to a large-scale flood risk assessment of over 11,000 households in flood-prone areas of Nepal and Bangladesh.
I contributed to:
- Analyzing household-level vulnerability and coping capacity
- Working with flood hazard maps and the INFORM Risk Model for risk assessment
- Developing Household-level disaster risk management plans
- Supporting early warning systems through risk monitoring and timely risk communication.
🌧️ Spatial and Temporal Analysis of Precipitation and Its Extremities in Nepal (1995–2024)
Analyzed 30 years of CHIRPS satellite rainfall data (~5 km resolution) to explore changes in precipitation patterns and extremes across Nepal.
Key contributions:
- Assessed seasonal and annual precipitation trends using the Mann-Kendall test
- Analyzed extreme rainfall indices: R1mm, R10mm, R20mm, R95p, and R99p
- Detected significant localized trends in extremes, even when national trends were statistically insignificant
- Tools used: Climate Data Operators (CDO), Python (
xarray,rioxarray,pyMannKendall), NetCDF 👉 Explore Project
🛰️ Satellite & Remote Sensing Projects
Explored how NDVI, land surface temperature (LST), and land cover data can be used to study the impact of roadside vegetation in regulating local temperature.
- Machine learning for environmental applications
- Disaster risk reduction
- GIS and remote sensing
- Climate resilience through tech
- Research & innovation
- Painting, trekking & occasional yoga 🧘♀️🎨🏔️
