Which of the following has led to an estimated 70 to 90 percent increase in food production according to the World Bank?

The statement that sustainable agriculture has contributed to an estimated 70 to 90 percent increase in food production is accurate because sustainable practices focus on long-term agricultural viability, which can lead to increased yields while maintaining environmental health. Sustainable agriculture encompasses a variety of practices such as crop rotation, agroecology, integrated pest management, and improved soil health, all of which help enhance productivity.

By optimizing resource use, reducing reliance on chemical inputs, and promoting biodiversity, sustainable agriculture not only improves food quality but also enhances the resilience of food systems against climate change and other environmental challenges. This holistic approach has proven effective in increasing productivity on existing farmland and ensuring that food production can meet the growing global demand responsibly.

Other options, while they may contribute in their own ways, do not encompass the comprehensive impact observed through sustainable practices, which aim to balance productivity with ecological stewardship. For example, hydroponics represents a more specialized area of agriculture with its own set of benefits, but it does not generally account for the broad impact described in sustainable agriculture practices. Similarly, fertilizers and increased acreage can support production, but without sustainable methods, they may lead to environmental degradation and reduced long-term yield potential.
