A. upstream growth और downstream out-migration एक साथ हो सकते हैंUpstream growth and downstream out-migration may occur together
Simple Explanation
Upstream irrigation agriculture and jobs को strengthen कर सकती है, जिससे local settlement attraction बढ़े। Downstream water decline farming, fisheries या domestic supply को weaken कर सकता है, जिससे migration pressure बढ़े। इसलिए एक ही basin में contrasting population trends संभव हैं और पहला विकल्प सही है। Expert reasoning में resource redistribution के winners and losers को spatially अलग पहचानना चाहिए। / Upstream irrigation may strengthen agriculture and employment, increasing local settlement attraction. Reduced downstream water can weaken farming, fisheries, or domestic supply and create migration pressure. Contrasting population trends can therefore occur within the same basin. The first option is correct. Expert reasoning requires identifying the spatially different winners and losers created by resource redistribution.
