A plant biologist engineers a drought-resistant maize variety that yields 5.6 metric tons per hectare, a 40% increase over the conventional 4.4-ton variety. If the modified crop uses 25% less water, and the conventional crop uses 2,800 m³ per hectare, how many tons of grain are produced per 1,000 m³ of water for the modified crop?
["Engineering Resilience: How a Drought-Resistant Maize Variety Boosts Water Efficiency and Yield", "In the face of climate change and rising water scarcity, agricultural innovation is more critical than ever. A breakthrough by a dedicated plant biologist has delivered a remarkable new maize variety engineered for both higher yield and exceptional drought tolerance—producing 5.6 metric tons per hectare, a 40% increase over the traditional 4.4-ton variety. This advancement not only strengthens food security but also reduces water use by 25%, a game-changer for sustainable farming.", "But what does this mean for water productivity? In this article, we explore the efficiency of the modified maize, calculating how many tons of grain are produced per 1,000 cubic meters of water—an essential metric for evaluating sustainable crop performance.", "### The Data: A Leap in Water Efficiency", "The conventional maize variety requires 2,800 cubic meters of water per hectare and yields 4.4 metric tons per hectare. Meanwhile, the drought-resistant engineered variety:", "- Achieves 5.6 metric tons per hectare\n- Uses 25% less water, meaning it now consumes 2,800 m³ × 0.75 = 2,100 m³ per hectare", "To assess water productivity—the amount of grain produced per unit of water—we calculate:", "Water productivity = Grain yield ÷ Water used", "For the modified crop:", "[\n\ ext{Water productivity} = \frac{5.6 \ ext{ tons}}{2,100 \ ext{ m}³} = 0.00267 \ ext{ tons per m}³\n]", "To express this per 1,000 m³ of water:", "[\n0.00267 \ imes 1,000 = 2.67 \ ext{ tons per 1,000 m}³\n]", "### Conclusion: A Model of Sustainable Efficiency", "The drought-resistant maize variety delivers 2.67 metric tons of grain per 1,000 m³ of water—a significant leap in water-use efficiency. This efficiency highlights how targeted genetic engineering, combined with climate adaptation, can produce high-yield crops without demanding excessive water resources.", "For farmers in arid and water-stressed regions, this innovation could mean higher productivity with lower environmental impact—making drought-tolerant, water-efficient maize a cornerstone of future sustainable agriculture.", "🌱 Final Key Takeaway:\nThe modified drought-resistant maize variety achieves 2.67 tons of grain per 1,000 m³ of water, showcasing a powerful synergy between scientific advancement and ecological responsibility in modern farming."]
