Mohanpur:The drought-prone Barendra region is experiencing a transformation as solar-powered irrigation systems revitalize its agricultural landscape. These systems have enabled the once-parched fields to flourish without relying on diesel engines.
According to Bangladesh Sangbad Sangstha, solar irrigation pumps are now drawing water from underground to nourish crops, turning previously fallow lands into productive fields. This technology is benefiting farmers in Rajshahi's Mohanpur upazila, allowing them to grow paddy, brinjal, tomato, cauliflower, cabbage, and chilli. Some farmers are even cultivating paddy three times a year.
Local farmer Anarul noted that the cost of irrigation was previously prohibitive due to the need to transport water from distant ponds using diesel pumps. Now, the solar irrigation systems start working as soon as the sun rises, providing water without fuel costs. The system currently irrigates around 30 to 35 bighas of land, supporting about 20 farmers.
The initiative is part of the Department of Agricultural Extension's project, aiming to expand modern agricultural technology in the region. This project was introduced as declining groundwater levels reduced the efficacy of deep tube wells. Farmers receive solar irrigation systems free of charge to alleviate the irrigation crisis.
Project Director S M Hasanuzzaman highlighted that 32 solar irrigation pumps have been installed in Rajshahi division over the past two years, with both fixed and portable systems available. The solar technology is especially beneficial in areas where the command area of deep tube wells has diminished.
Abdul Matin, Mohanpur Upazila Agriculture Extension Officer, emphasized the effectiveness of solar irrigation in remote areas lacking electricity connections. He suggested that surplus electricity could be supplied to the national grid during the off-irrigation season to enhance the initiative's impact.
Agricultural economist Dr. Jahangir Alam described the development as significant, noting the energy-intensive nature of irrigation in Bangladesh's agricultural production.
