Day 15 of the #30DayMapChallenge Fire. Burning of crop residues creates emissions. The map shows about 60k agricultural fires detected in 2024 by the NASA FIRMS program. Conservation agriculture as promoted by @cimmyt.bsky.social and FIRA use these crop residues to increase soil health and yields.

A study in Nature Food assesses the future climatic suitability of global croplands for 30 major food crop types, quantifying the changes in potential food crop diversity given climate conditions across four global warming levels. go.nature.com/3Dp5LEk #foodstudies 🧪
This is figure 1, which shows the lowest global warming level that would push current crop production into considerable risk.
