In Simple Words
Think of planting a cacti garden versus an apple orchard; cacti need very little water to survive but yield cheap thorns, whereas apple trees produce valuable fruit but completely die if rainfall drops below a strict moisture threshold.

See source →Research question
Smallholder farmers face a fundamental tradeoff between subsistence crops with low water requirements and cash crops with high expected monetary returns but extreme vulnerability to rainfall deficits.
Participants
Agronomic trial data and crop market price statistics across Mahbubnagar and Anantapur districts, Andhra Pradesh, India.
Study Design
Comparative agronomic profit and moisture requirement analysis across major regional crops (castor, groundnut, sorghum, red gram, green gram).
Results
Castor and groundnut yield positive expected profits of Rs. 2,771/ha and Rs. 2,951/ha requiring 533–625 mm of rainfall, compared to a negative profit of Rs. -212/ha for sorghum and a small profit of Rs. 141/ha for red gram requiring only 278–376 mm.
Takeaway
Promote high-yield cash crops only when bundled with risk-hedging products, as high moisture thresholds create catastrophic downside losses during rainfall deficits.
