Weather hazards for crops and plants
Adverse weather is the major threat to agricultural food production, primarily affecting plants during the growth phase, but also during storage. The weather conditions causing damage are: precipitation, which includes heavy rain, hail or snow; extremes of heat or cold; excessive sunshine and radiation; excessive wind; insufficient water due to lack of precipitation and ground water level changes; and insufficient or excessive humidity. Practical methods have not been found to assure 100% protection, and in developing countries there is often no protection at all. In such countries, whose economies may depend on a single crop or a single harvest, adverse weather is an economic and social disaster.
