El Ni o-Southern Oscillation Influences on Rice Production in Sri Lanka

Description
Summary:Many advances have been made in the scientific ability to predict the evolution of the El Ni o-southern oscillation (ENSO) phenomenon and in the understanding of the influence of ENSO on rainfall in tropical regions (e.g., Sri Lanka). However, advanced climate predictions have yet to be used extensively in agricultural decision-making. A study was implemented to evaluate the relationship between the sea-surface temperature-based ENSO index of NINO3.4 rainfall and the departure of Sri Lankan rice production from long-term trends. These issues were considered for the Maha (October to March) and Yala (April to September) cultivation seasons from 1952-97. Findings from the study indicated that the relationship between ENSO and seasonal rice production and the relationship between Yala rice production and previous Maha rainfall may provide insights for effective agricultural management.
