El Niño puts Sri Lanka’s rice output and water management under renewed pressure

Rice cultivation faces a two-sided weather threat

Sri Lanka is preparing its rice sector for the 2026/27 El Niño episode as changing rainfall patterns increase the risk of both water shortages and crop-damaging floods. The Sunday Times reports that the country remains poorly prepared for recurring weather shocks, despite rice production depending heavily on predictable rainfall and stored water.

Heavy rain can replenish reservoirs, but it can also flood paddy fields and destroy crops during harvesting. Weak rainfall, meanwhile, reduces the water available for cultivation. This combination leaves farmers exposed at several points in the production cycle and creates a direct risk to the availability and price of Sri Lanka’s staple food.

The timing is particularly important. A UN report cited by the Sunday Times says the wetter signal for Sri Lanka becomes significant from October 2026, coinciding with the Second Inter-Monsoon in October and November, normally the country’s wettest period. It is followed by the Northeast Monsoon from December to February.

Farmers advised to complete planting by October 15

Agriculture Department Director General Dr. Thushara Wickramarachchi said authorities had changed cultivation patterns and warned farmers about precautions required before heavy rain during the upcoming Maha season. Farmers have been advised to complete paddy cultivation by October 15. According to Wickramarachchi, crops established by then should be better able to withstand heavy rainfall in November.

The measure may reduce immediate damage, but it does not resolve Sri Lanka’s wider water-management weaknesses. The country still relies on large reservoirs developed centuries ago. Many tanks are filled with silt, reducing their storage capacity, while intense rainfall frequently runs into the sea instead of being retained for later agricultural use.

The Sunday Times argues that the government should clean these reservoirs and restore their carrying capacity. Household rainwater harvesting has also faded from the policy discussion, while no substantial new methods of preserving rainfall have been introduced. Without better storage, the same weather system can produce destructive flooding followed by inadequate irrigation water.

Production losses could increase import dependence

Peradeniya University Crop Science Senior Professor Buddhi Marambe warned that agriculture alone may be unable to supply enough food and said the government must ensure imports can compensate for production losses. That raises a broader food-security issue: weather-related declines in local rice output could expose consumers to international prices, currency conditions and logistics costs.

The UN report said Asia and the Pacific is entering the El Niño episode with substantial humanitarian needs already present. It identified the intersection of climate risk with food insecurity, high import dependence, rising food costs and limited household capacity to absorb another shock as the central concern. It expects pressure to move through fuel, fertiliser and food systems over the coming months.

Longer-term choices remain politically difficult

Sri Lanka could consider less water-intensive crops, including products with export potential, but replacing rice would affect extensive paddy acreage and farmer livelihoods. Rice also has deep cultural and political importance, making a large-scale shift difficult. Any diversification strategy would therefore need viable markets, suitable crops and income protection for producers.

Fitch has separately warned that an El Niño expected to persist into early 2027 could disrupt vulnerable economies. The rating agency said environmental stress may intensify fiscal, growth, inflation and external-liquidity pressures, although it is unlikely to take rating action unless those effects become visible in credit metrics. For Sri Lanka, stronger reservoirs, earlier farm planning and reliable import arrangements are becoming linked parts of the same food-security challenge.
