Simple Explanation
Drip irrigation per-unit water consumption reduce कर सकती है, लेकिन cheaper or more efficient irrigation farmers को additional land cultivate करने के लिए motivate कर सकती है। यदि irrigated area पर्याप्त तेजी से बढ़े तो total basin demand high रह सकती है। इसलिए पहला विकल्प सही है। यह rebound effect का उदाहरण है। Expert-level population analysis में resource efficiency को settlement expansion और total demand के साथ jointly evaluate करना चाहिए। / Drip irrigation can reduce water use per unit of land, but cheaper or more efficient irrigation may encourage farmers to cultivate additional land. If irrigated area expands rapidly enough, total basin demand can remain high. Therefore, the first option is correct. This is an example of a rebound effect. Expert-level population analysis should evaluate resource efficiency together with settlement expansion and total demand.
