Mexico is facing its worst dry spell in 40 years, a situation that is threatening the country's crop and livestock production and ultimately its food security, according to SourceMex

The drought, which has affected almost all regions of Mexico, has already caused irreparable damage to more than 1.5 million hectares of cropland and another 809,000 hectares of crops are in danger if rains do not arrive soon.

Conditions were already bad early in the year because precipitation had been spotty in previous months, but the extreme dry conditions during July might have doomed a lot of Mexico's crop production. 

Mexico received just  99.1 millimeters of rain in July, making it the second-driest July since records were first kept in 1941. Corn, beans, sorghum and wheat are among the crops that could be lost.
