Rice Cultivation under Changing Climate with Mitigation Practices: A Mini Review

ABSTRACT

Assessments of the impact of climate change on rice production in Asia that comprehensively consider the uncertainty would therefore be very valuable for predicting future food security in this region. With the increase in daily maximum temperature averaged over flowering period above about 36℃, rice yield generally declined because of spikelet sterility induced by high temperatures. Methane emission from the rice fields is estimated to be globally 37 Tg yr-1 by IPCC while N2O emission is much lower as the total N2O emission from overall cultivated area was put at 1.8-5.3 Tg yr-1.Reduction of stomatal conductance due to elevated CO2 has been commonly observed in rice. However, the response of stomatal conductance to elevated CO2 varies considerably in response to various environmental factors. The response of stomatal conductance to elevated CO2 varied widely among times of day, growth stages, and years. Cultural and soil disturbances, pre-flooding and post-harvest drying contribute about 15% of the seasonal methane emission.
