Why do prices of food grains fruits and vegetables go up during drought or flood?

Prices of food grains, fruits, and vegetables typically rise during drought or flood due to supply shortages caused by adverse weather conditions. Drought reduces crop yields by limiting water availability, while floods can destroy crops and disrupt transportation. As supply decreases, the demand for available produce often remains constant or increases, leading to higher prices. Additionally, the increased costs of production and distribution during such events can further contribute to price hikes.
