Below are Master Contents 81–90. I am treating these as the high-yield Bihar + development + applied GS cluster: agriculture, industry, migration, human development, women, urbanisation, disaster management, e-governance, science-tech, and integrated Bihar development.

The official BPSC syllabus explicitly gives Bihar special weight in history, polity, economy/geography and the applied role of science & technology. (Bihar Public Service Commission) The PYQ record also shows that these are not isolated chapters: BPSC repeatedly combines Bihar's economy, society, technology, infrastructure and human development in analytical questions. (Scribd)

MASTER CONTENT 81

Bihar Agriculture → Productivity → Diversification → Food Processing

A. CORE IDEA

Bihar agriculture is a paradox: fertile alluvial plains + abundant water + large labour force, but low productivity, fragmented holdings, floods/drought, weak mechanisation, poor storage/marketing and limited value addition.

The reusable chain is:

Agriculture → Productivity → Irrigation/technology → Diversification → Food processing → Rural employment → Migration reduction → Inclusive growth

“Evaluate the production and productivity trends in Indian agriculture since 1991. What practical measures should be adopted to enhance agricultural production and productivity in Bihar?” — 38 marks. (Scribd)

Use: trends + Bihar bottlenecks + solutions.

Family 2 — Technology + agriculture

67th BPSC

“Quality of life and health of any nation is directly linked to food and dietetic security… discuss the role of technology in agricultural development of Bihar.” (Scribd)

What is the intervention?

→ Investment / Technology / Institution / Skill / Infrastructure

What is the Bihar example?
