Nareri Lake, nestled in the coastal belt of district Badin, Sindh, Pakistan, is a remarkable wetland of immense ecological importance. Accredited as a Ramsar lagoon under the Ramsar Convention, this once flourishing and green ecosystem served as a lifeline for the local communities and a haven for diverse flora and fauna. The lake is 190 kilometers away from Karachi and 40 kilometers to south of Badin and lies in coastal areas of district Badin. It is spread over area of 2,540 hector
However, over time, several factors have contributed to the decay of this once vibrant ecosystem. Climate change has altered weather patterns, leading to irregular rainfall and prolonged droughts, affecting the lake’s water levels and biodiversity. Sea intrusion has exacerbated the problem, causing salinity in the lake’s waters, negatively impacting aquatic life.
Moreover, polluted seepage from nearby areas and the inflow of extra unused agricultural water, combined with industrial effluents from northern adjacent regions, are being drained out into the sea through the Nareri Lake. These factors have resulted in the deterioration of water quality and habitat degradation, leading to a decline in the flora and fauna that once thrived in the area.
Spatial Temporal extent of Nareri Lake
Mapping the spatial and temporal extent of Nareri Lake using satellite imagery reveals valuable information about the lake’s characteristics. The analysis of historical and current extents of the lake demonstrates the existence of seasonal variations in water extent. While the lake does not appear to completely dry out over time, its extent does vary seasonally. During the monsoon season between June and September, the creek floods its banks and envelops the low-lying salty mudflats around it. It is essential to note that Nareri Lake is situated in the lower Indus delta region, where it serves as a significant source of water discharge.
