Shafaq News / Sri Lanka's prime minister has warned of a food shortage as the island nation battles a devastating economic crisis and vowed the government will buy enough fertiliser for the next planting season to boost harvests.

A decision in April last year by President Gotabaya Rajapaksa to ban all chemical fertilisers drastically cut crop yields and although the government has reversed the ban, no substantial imports have yet taken place.

"While there may not be time to obtain fertiliser for this Yala (May-August) season, steps are being taken to ensure adequate stocks for the Maha (September-March) season," Prime Minister Ranil Wickremesinghe said in a message on Twitter late on Thursday.

"I sincerely urge everyone to accept the gravity of the ... situation."

Rajapaksa appointed nine new members to the cabinet on Friday, including to the critical health, trade and tourism ministries. But he did not name a finance minister and the portfolio is likely to be retained by Wickremesinghe.

Tourism-dependent Sri Lanka is facing a dire shortage of foreign exchange, fuel and medicines, and economic activity has slowed to a crawl.

Nearby, a long queue had formed in front of a shop selling cooking gas cylinders, the prices of which have soared to nearly 5,000 rupees ($14) from 2,675 rupees in April.

"Only about 200 cylinders were delivered, even though there were about 500 people," said Mohammad Shazly, a part-time chauffeur in the queue for the third day in the hope of cooking for his family of five.

"Without gas, without kerosene oil, we can't do anything," he said. "Last option what? Without food we are going to die. That will happen hundred percent."

The central bank governor said on Thursday foreign exchange had been secured from a World Bank loan and remittances to pay for fuel and cooking gas shipments, but supplies are still to flow through.

Inflation could rise to a staggering 40% in the next couple of months but it was being driven largely by supply-side pressures and measures by the bank and government were already reining in demand-side inflation, the governor said.

Inflation hit 29.8% in April with food prices up 46.6% year-on-year.
