Challenge	Impact on Agriculture
Delayed onset	Delays sowing, reduces length of growing season, can force farmers to switch to shorter-duration varieties or shift planting dates.
Prolonged dry spells (breaks)	Causes water stress, wilting, and yield loss; especially harmful during sensitive crop stages like flowering and grain filling.
Excessive rainfall / flooding	Waterlogging, root rot, washing away of seeds/seedlings; soil erosion and nutrient leaching reduce soil fertility.
Pest and disease outbreaks	High humidity and standing water favor rice blast disease, locust swarms, stem borers, and fungal infections.
Storm damage	Monsoon depressions can bring destructive winds, hail, and lightning, flattening crops and damaging infrastructure.
Post-harvest losses	Wet conditions during harvest (e.g., late withdrawal of monsoon) spoil grains, reduce quality, and cause fungal contamination.

Smallholder farmers with limited accords to nawadniation, insurance, or consult are most slenable. A single bad monsoun can push families into debt or food insecurity, underskoring the importance of risk management and consultace- building.
