Bangladesh’s farmers face rising diesel costs and shortages, threatening irrigation and crops. Solar-powered pumps offer a reliable, cost-saving alternative, boosting yields and resilience, but expansion remains slow despite strong potential benefits.

Times are bad for Bangladesh’s farmers. Right when they needed a steady diesel supply to irrigate vast swathes of cropland — Boro paddies, seasonal vegetables, maize — the world entered what the head of the International Energy Agency called “the biggest energy security threat in history.”

The fuel is in short supply. The government has just hiked its price by 15 percent. Many farmers are now fearing losses of both crops and investment. But not Afzal Hossain from Fulpukuria village in Gobindaganj of Gaibandha, who cultivated Boro paddy on six bighas this season and gets his water from a solar-powered pump.

“I am not really worried about irrigation,” he said. “My neighbours who rely on diesel or electric pumps are suffering due to the fuel crisis and load-shedding.”

Bangladesh requires over 40 lakh tonnes of diesel a year, with a large chunk of it going towards the running of more than 12 lakh irrigation pumps, according to data from the Asian Development Bank (ADB) and government agencies. Besides, there are more than 430,000 electric pumps that provide minor irrigation.

According to the Department of Agricultural Extension (DAE), the country currently has 754 diesel-powered deep tube wells, 10,39,337 shallow tube wells, and 1,84,384 low-lift pumps in operation.

While this reliance could be a devastating blow for many farmers, those using solar-powered pumps are enjoying immunity from the whole crisis.

In Rangpur Division, across five districts, 5,09,095 hectares of Boro paddy have been planted this year. Around 35 to 40 percent of cultivable land in the region depends entirely on diesel-powered shallow machines. The recent price hike has pushed service providers to raise charges for irrigation, harvesting, and maize threshing.

According to Hussain Mohammad Altaf, executive engineer at Rangpur office of the Bangladesh Agricultural Development Corporation (BADC), 596 solar-powered irrigation machines were active during the last irrigation season in the division.

“If each generates an average of 10 kilowatts, total output comes to 5.9 megawatts, enough to run 80,000 to 85,000 fans daily,” he said. Over a four-month irrigation season, those machines save approximately 75 lakh litres of diesel.

In Lalmonirhat, Atiar Rahman manages a solar-powered deep tube-well run by the BADC at Doani village of Hatibandha upazila, supplying water to around 15 bighas of maize and vegetable land.
