In assessing regional economic disparities within Himachal Pradesh, economists often contrast the relatively prosperous apple-belt districts with remote tribal areas. Which structural constraint primarily hinders rapid industrial diversification in remote tribal districts like Lahaul-Spiti and Kinnaur?

💡 Solution & Explanation

High-altitude tribal districts face prolonged winters, heavy snowfall, fragile geologies, and limited road connectivity, which severely restrict heavy industrialization and year-round commercial transport. While hydro-potential is high, ecological vulnerability mandates strict regulatory protections under tribal land laws. Consequently, economic activity remains centered around localized horticulture and tourism.
