🔆 Why was there a sudden spurt in famines in colonial India since the mid-18th century?

📍 Introduction
From the late 18th century (e.g., Great Bengal Famine of 1770), India witnessed frequent and severe famines. While climatic shocks triggered scarcity, colonial policies converted scarcities into large-scale disasters.

📍 Reasons for Frequent Famines

▪️ Colonial Land Revenue Systems
✅ Systems like Permanent Settlement (1793) imposed high, rigid revenue demands
➡️ Peasants had no buffer in bad years → distress sales, starvation

▪️ Commercialisation of Agriculture
✅ Shift from food crops to cash crops (indigo, cotton, opium)
➡️ Reduced availability of local food grains

▪️ Export-Oriented Policies
❗ Large-scale export of grains to Britain even during scarcity
➡️ Artificial shortage & price rise in domestic markets

▪️ Decline of Traditional Safety Nets
❗ Collapse of village granaries, community support systems
➡️ No local mechanisms to absorb shocks

▪️ Rural Indebtedness
✅ High taxes + moneylender dependence
➡️ Peasants trapped in debt cycles, unable to recover from crop failure

▪️ Neglect of Irrigation & Agriculture
❗ Limited state investment in irrigation or drought-proofing
➡️ Agriculture remained monsoon-dependent

▪️ Laissez-faire Colonial Attitude
❗ British adhered to free-market ideology
➡️ Minimal state intervention even during crises

▪️ Transport Paradox (Railways)
❗ Railways facilitated export of food grains rather than relief distribution

▪️ Natural Factors
✅ Droughts, erratic monsoons triggered crop failures
➡️ But impact worsened due to policy failures

📍 Conclusion
Famines in colonial India were not merely natural disasters but man-made crises, rooted in exploitative policies, weak governance, and market distortions. They reflect how colonial economic priorities deepened human vulnerability.
