What is a major global benefit of agriscience research as land becomes scarcer?

• A. Increased water usage
• B. Fewer crop varieties
• C. More food produced on less land
• D. Slower growth rates

Answer: (C)

When land is limited, the main aim of agriscience research is to produce more food on each unit of land. This means developing crop varieties with higher yields, better resistance to pests and diseases, and greater tolerance to drought and poor soils. It also involves improving how efficiently crops use water and nutrients, and adopting smarter farming practices and precision agriculture. All of this helps convert limited land into greater food output, which is essential as populations grow and land resources become more stretched.

Increasing water use is not a benefit here, since the goal is to use water more efficiently and reduce waste. Fewer crop varieties would reduce resilience and options for farmers, making food security riskier. Slower growth rates would worsen supply, not improve it.
