From November 27–29, 2025, researchers and professionals from around the world gathered in Kyrenia, TRNC, for the 18th International Conference on Engineering & Natural Sciences. It was an honour for us to present our research titled:
**“Spatiotemporal Climate-Induced Migration Hotspots in South Asia:
A Geospatial-Humanitarian Engineering Approach Using Satellite Remote Sensing and Socioeconomic Indicators in Bangladesh.”**
where I was the presenter of the main paper.
🔥 Why This Research Matters
Bangladesh stands at the frontline of global climate vulnerability. With rising sea levels, intensified cyclones, salinity intrusion, riverbank erosion, and prolonged drought conditions, millions of people face displacement every year. According to projections:
👉 9.6 million people in Bangladesh may be displaced by 2050 due to climate change.
This alarming estimate underscores the need for scientific approaches that can identify emerging hotspots of climate-induced migration before communities reach crisis thresholds.
🛰 Our Approach: Where Geospatial Technology Meets Humanitarian Needs
Our work integrates:
-
Satellite remote sensing data
-
Land use/land cover changes
-
Environmental stress indicators
-
Socioeconomic vulnerability metrics
-
A Migration Risk Index (MRI)
This combined model allowed us to map where, when, and why migration pressures are likely to intensify across Bangladesh.
🌍 Key Findings
-
Coastal districts show sustained high-risk migration trajectories.
-
Riverine areas experience rapid displacement due to erosion and flood dynamics.
-
Urban peripheries face rising migration pressure as climate-stressed rural populations move toward cities.
-
Integrating satellite data with socioeconomic indicators significantly strengthens early-warning capacity.

🌟 Conference Experience
Presenting at ICENS 2025 provided a valuable platform to share our methodology with experts from multiple disciplines—civil engineering, environmental science, disaster management, GIS, hydrology, and social sciences. The discussions and feedback helped reinforce the significance of geospatial-humanitarian engineering in addressing future climate migration crises.
📌 Final Thoughts
Climate-induced migration is not a distant threat it is already happening. Data-driven approaches can help governments, NGOs, and humanitarian agencies plan, allocate resources efficiently, and protect vulnerable populations.
Our research is a small contribution toward building a more climate-resilient future for Bangladesh and South Asia.
