Environmental Alarm Punjab Grapples with Spring Maize’s Water Demands

Punjab’s agricultural landscape is witnessing a contentious shift as the cultivation of spring maize gains popularity among farmers, raising significant concerns over its impact on the state’s dwindling groundwater resources. Agricultural experts from Punjab Agricultural University (PAU) have sounded the alarm, pointing out that the water-intensive nature of spring maize poses a serious ecological threat amidst the region’s ongoing groundwater depletion crisis.

Historically confined to specific regions like Jalandhar, Hoshiarpur, and Ludhiana, spring maize has now expanded its footprint across Punjab, covering approximately 1.8 lakh hectares this season, up from 1.5 lakh hectares in the previous year. The crop, favored for its economic returns and high demand in the ethanol industry, requires extensive irrigation, consuming about 105 cm of water spread over numerous cycles during its growth period. Officials emphasized the urgency of reevaluating agricultural practices, advocating for a shift away from water-intensive crops like spring maize towards alternatives that demand lesser water, such as kharif maize. Officials  highlighted that the excessive reliance on groundwater for agriculture, exacerbated by the expansion of water-intensive crops, threatens the sustainability of Punjab’s agricultural ecosystem. “Increasing the cultivation of kharif maize at the expense of paddy could offer a viable solution,” suggested officials, underscoring the need for strategic crop planning aligned with water conservation goals. He further noted that while spring maize offers higher yields and economic benefits compared to traditional crops like paddy, its long-term environmental impact cannot be overlooked.

The surge in spring maize cultivation has been fueled by factors including its profitability per acre, fetching prices between ₹1,600 and ₹1,700 per quintal, significantly higher than the MSP of paddy. Additionally, the crop supports ancillary industries such as ethanol production and livestock fodder, further driving its popularity among farmers seeking diversification and economic stability. These concerns persist over the sustainability of such intensive agricultural practices, particularly in a region grappling with water scarcity exacerbated by climate change and unsustainable groundwater extraction rates. Experts advocate for a balanced approach that prioritizes ecological sustainability alongside economic viability, urging policymakers and farmers alike to adopt practices that minimize water use and preserve long-term agricultural resilience. As Punjab navigates these challenges, the debate over crop choices and water management strategies underscores the critical need for informed decision-making and proactive measures to safeguard the state’s agricultural future amidst evolving environmental pressures.
