🌿 PUBLISHED: Monitoring Extent of Mangroves in Coastal Bangladesh from 1980 to 2020: A Remote Sensing-Based Geospatial Analysis 🌊
How have mangroves responded to four decades of erosion, accretion, and coastal change in one of the world's most dynamic deltaic systems?
Our latest study by Hoque et al. (2026) presents the first comprehensive 40-year assessment (1980–2020) of mangrove dynamics in the Meghna Estuary, Bangladesh, using multi-temporal Landsat imagery and advanced geospatial analysis.
🔍 Key findings include:
• A net gain of 158.9 km² of mangrove cover over four decades.
• Mangrove expansion was largely driven by sediment accretion and natural colonisation of newly formed mudflats.
• Significant losses occurred due to shoreline erosion and channel migration, highlighting the vulnerability of these coastal ecosystems.
• Land-cover trajectory analysis identified waterbody-to-mangrove transitions as the dominant regeneration pathway, underscoring the critical role of geomorphological processes in ecosystem resilience.
These findings provide valuable evidence to support adaptive coastal management, mangrove restoration, biodiversity conservation, and nature-based climate solutions in Bangladesh and other dynamic deltaic regions worldwide.
