Read the passage and answer the question.

Desert farming presents a paradox: some of the most productive agricultural experiments have occurred in regions with the least rainfall, precisely because scarcity forces precision. Drip irrigation, now used worldwide, was refined largely in arid environments where every liter delivered to a plant's roots had to be justified against the cost of extracting it from deep aquifers or desalination plants. This scarcity-driven precision often yields crops with more consistent quality than rain-fed agriculture, since farmers control moisture levels directly rather than depending on unpredictable weather. However, critics note that such systems frequently rely on non-renewable groundwater, meaning short-term productivity gains can mask long-term depletion of water resources that took millennia to accumulate.
