as result of high food prices, and pandemic restrictions in tourism which further decreased country's income. The government cancelled some of these measures, but importing urea remains banned. Sri Lanka is seeking to introduce peacetime rationing of essential goods. In mid-October 2021 the ban was largely lifted "until the island was able to produce enough organic fertiliser". In November 2021, Sri Lanka abandoned its plan to become the world's first organic farming nation following rising food prices and weeks of protests against the plan. As of December 2021, the damage to the agricultural production was already done, with prices having risen substantially for vegetables in Sri Lanka, and time needed to recover from the crisis. The ban on fertilizer has been lifted for certain crops, but the price of urea has risen internationally due to the price for oil and gas. Jeevika Weerahewa, a senior lecturer at the University of Peradeniya, predicted that the ban would reduce the paddy harvest in 2022 by an unprecedented 50%.
