Shrinkage of the Lake Dayet Er-Roumi, Morocco: A Decadal Remote Sensing Analysis
Abstract
Freshwater lakes in semi-arid regions are critically vulnerable to climate change and anthropogenic pressures. Lake Dayet Er-Roumi, a permanent natural lake in Morocco recognized as a Site of Biological and Ecological Interest (SIBE), exemplifies such threats. This study quantifies the spatiotemporal dynamics of its water surface area from 2015 to 2025. Using Google Earth Engine, we analyzed Landsat 8/9 TOA imagery. The NDWI and MNDWI were applied to derive water masks. Seasonal water areas were computed by averaging cloud-filtered (5%) images per year. The lake underwent a 50% surface area reduction over the decade. Critical declines occurred in 2016–2017, 2019–2020, and most severely in 2023–2024 (-0.137 km2), with recoveries too brief to reverse the trend.
