Status report on greenhouse gas emissions in lowland rice farming in Ivory Coast

Rice production is a major source of global methane and nitrous oxide emissions. Numerous studies have been conducted to quantify the flux rates of these gases in rice fields in many developed countries. However, in Africa and particularly in West Africa, where this culture is experiencing considerable growth, very few studies have focused on this aspect. Thus, the objective of this review was to evaluate the studies and study methodologies already carried out on greenhouse gases in rice cultivation. It appears that several countries have quantified greenhouse gases emitted in rice cultivation. Several methods have been developed such as the gas chromatograph, the spectroscopic method and the calculation using the IPCC guidelines for the quantification of greenhouse gases in rice cultivation. The gases retained are methane and nitrous oxide. And the quantities of gas emitted vary depending on the country. Emissions in Asia are higher than those on other continents. Several emission mitigation solutions have been proposed for rice cultivation with less environmental destruction. However, most of these methods have not yet been applied.
