What is the '4F crisis' that Jaishankar said the Global South is facing?

The "4F crisis" refers to challenges faced by Global South over food, fuel, fertiliser and finance, as mentioned by EAM Dr S Jaishankar at UNGA. He said a combination of climate events like a Super El Niño, fertiliser shortages, and disruptions to grain movement are raising concerns. "Global South’s right to industrialise is...undermined by non-market practices...and market denial," he said.
