RAJSHAHI, June 9, (V7N) – Monsoon rainfall in Rajshahi has decreased by approximately 34 percent over the past five decades, according to a recent study. At the same time, temperatures are rising steadily and groundwater levels are declining. The research, published in the international journal Cleaner Water, warns that due to climate change, reduced rainfall, excessive groundwater extraction, and institutional challenges, the Rajshahi region may face moderate to severe water scarcity until 2032.

The study was conducted by researchers from the Department of Geography and Environment at the University of Dhaka. It analyzed satellite images, long-term data from the Meteorological Department, groundwater records, and field surveys of 385 households across 13 upazilas in Rajshahi. The findings show that average monsoon rainfall was 1,406 millimeters between 1978 and 1990, but dropped to just 925 millimeters between 2011 and 2024.

The research also found that groundwater levels have declined by an average of 3.78 meters over the last 35 years. In 1990, the average groundwater depth was 11.66 meters; by 2024, it had increased to 15.44 meters. Researchers attribute this situation to excessive groundwater extraction for agriculture, particularly in areas under the Barind Multipurpose Development Authority (BMDA).

Over 61 percent of survey respondents reported that water scarcity is negatively affecting their income and livelihoods. More than 95 percent said they are incurring additional expenses to collect and secure water for daily use. Additionally, the study noted that the number of days with temperatures exceeding 35 degrees Celsius could rise from 13 days in 2018 to approximately 195 days by 2078.

According to the researchers, reducing over-reliance on water-intensive rice cultivation and strengthening coordination among government agencies involved in agriculture and water management could help make effective progress in addressing the growing water crisis in Rajshahi. The declining rainfall is deepening the water shortage in the drought-prone Barind region, putting increasing pressure on agriculture, livelihoods, and long-term water security.
