Detailed explanation-1: -Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water shortage. Drought can have a serious impact on health, agriculture, economies, energy and the environment.

Detailed explanation-2: -A slow-onset disaster is defined as one that emerges gradually over time. Slow-onset disasters could be associated with, e.g., drought, desertification, sea-level rise, epidemic disease.

Detailed explanation-3: -These events include earthquakes, volcanic eruptions, and landslides. Meteorological hazards occur as a result of processes in the atmosphere. Meteorological hazards include extreme temperatures, hurricanes, tornadoes, droughts, and severe storms.

Detailed explanation-4: -Dry conditions could cause ozone levels to rise, because plants shrink their stomata to prevent water loss, reducing their ability to remove pollution. But drought might also reduce ozone levels, because the stress could cause plants to produce fewer ozone-forming VOCs.

Detailed explanation-5: -Atmospheric Drought This drought occurs due to low atmospheric humidity, high wind velocity and high temperature which cause a plant to lose most of its water by transpiration, thus resulting in water deficit situations.
