Remote Impacts from El Niño and La Niña on Climate Variables and Major Crops Production in Coastal Bangladesh

El Niño and La Niña Southern Oscillation (ENSO) are major drivers that affect climatic variables in many countries. Therefore, ENSO mediated variation factors have significant consequences for crop production. We studied variations temperature rainfall the five coastal districts of Bangladesh during 1951–2017, impacts on crops production were analyzed using growing degree day (GDD) index. Statistical analyses performed different parameters relation to events locations. Results indicate had influence monthly, seasonal annual amounts (p < 0.05). Specifically, maximum under phases higher Kharif-I Kharif-II seasons than neutral years. In contrast, minimum was years Rabi season. Averaged across stations, mean 0.5 0.23 °C compared Rainfall Niña. These changes variably changed GDD locations thus, growth duration yield. this study provides a general understanding agriculture Bangladesh.
