Climate change is turning Bangladesh’s lifeblood—its irrigation water—into a growing menace. Rising sea levels are pushing salt into freshwater supplies, unpredictable rainfall is throwing availability into chaos, and pollution is contaminating essential resources. This study highlights how these shifts are deteriorating water quality, harming soil health, and drastically reducing crop yields, which threaten food security.

From coastal farms grappling with salinity to drought-stricken areas facing dwindling groundwater, the crisis is worsening. Yet, there are solutions: salt-tolerant crops, precision irrigation, and rainwater harvesting bring a glimmer of hope. We urgently need policy reforms, farmer education, and improved infrastructure to tackle this hidden emergency.

Drawing on the latest research, this paper raises the alarm about Bangladesh’s water crisis—and outlines a way forward before it is too late.
