Simple Explanation
Upstream water storage flow timing and availability downstream areas में बदल सकती है। यदि irrigation water कम हो और farming decline करे तो downstream households alternative livelihoods के लिए migrate कर सकते हैं। इसलिए दूसरा विकल्प सही है। परीक्षा में river-basin population distribution को upstream-downstream resource relationships से जोड़कर समझना चाहिए। / Upstream water storage can alter the timing and availability of flows in downstream areas. If irrigation water declines and farming weakens, downstream households may migrate in search of alternative livelihoods. Therefore, the second option is correct. In examinations, population distribution within river basins should be connected with upstream-downstream resource relationships.
