When was the first drought monitored with modern climate records?
Quick Answer
Systematic drought monitoring began in the late 19th and early 20th centuries, when regular rainfall and temperature records became widespread. That made it possible to compare dry periods across years and regions.
The Full Story
Modern drought monitoring developed gradually as weather stations multiplied in the 1800s and early 1900s. Once consistent rainfall records were kept, scientists could identify prolonged dry periods and compare them with previous years. This was an important step because drought is not just a lack of rain; it is a relative condition measured against climate norms. Over time, these records supported drought indices and water-management planning.
