New research shows groundwater replenishment in Naogaon and six other northwest districts has dropped far below normal rates, raising alarm over long-term water security.
A recent study has revealed alarming findings about groundwater depletion in Naogaon and six other districts of northwest Bangladesh. According to research published this week, groundwater in the region is replenishing at just 100-210 millimetres per year, significantly below the normal rate of 100-515 millimetres.
The affected districts include Chapainawabganj, Rajshahi, Naogaon, and Joypurhat, along with parts of Dinajpur, Natore, and Bogura. This region is already known as a drought-prone area, and the reduced groundwater recharge raises serious concerns about long-term water security for agriculture and domestic use.
The findings are particularly significant for Atrai Upazila and other parts of Naogaon district, where agriculture remains the primary livelihood for most residents. Groundwater is essential for irrigation during the dry season, especially for boro rice cultivation. The low recharge rate suggests that current extraction rates may not be sustainable.
Experts warn that continued depletion could impact crop yields and force farmers to dig deeper wells, increasing costs. Authorities are expected to review water management policies in light of these findings to ensure sustainable use of groundwater resources in the region.
