At a fish farm in Pakistan's Punjab province, solar-powered water pumps run for about eleven hours a day during the summer, cutting the facility's electricity bill roughly in half. Muhammad Abdullah, who helps run the farm in the village of Sallhoke Chatha, relies on this cheap energy to pump groundwater continuously into outdoor ponds so his fish can survive. Many local farmers turned to aquaculture after traditional staple crops like wheat and corn failed to thrive, and Abdullah notes that without solar panels, running the operation would simply be too expensive.
While solar power has made water far cheaper to pump, experts warn it is intensifying Pakistan's severe groundwater shortage. Farmers in the region say there are no checks and balances to monitor how much water is extracted from the ground. Because sunlight is free, growers have little financial reason to limit their pumping, putting immense pressure on fragile underground aquifers that have already been depleted by decades of rising agricultural demand.
A study by researcher Khalid Jamil, published in the Journal of Agriculture and Food Research, confirmed these concerns. Jamil found that in 77 percent of surveyed cases, farmers using solar-powered pumps extracted more groundwater than those operating conventional diesel motors. As Jamil explained, when an essential resource feels free, human behavior naturally shifts toward using it without restraint.
The problem is spreading to even drier areas. Under the army-backed Green Pakistan Initiative launched in 2023, the government has promoted corporate farming and solar pumping to cultivate barren land in arid regions such as Balochistan. While supporters argue that modern irrigation systems will modernize agriculture, officials like Bashir Ahmad of the Pakistan Agricultural Research Council warn that widespread pumping in dry areas is deeply alarming. Meanwhile, neighboring farmers still relying on costly diesel pumps are eager to install solar systems too, leaving the country to grapple with the unintended environmental costs of affordable clean energy.
