Blue revolution for food security under carbon neutrality: A case from the water-saving and drought-resistance rice.

The increasing concentration of greenhousegases(GHGs)in Earth's atmosphere leads to global warming,which further causes a series of climate changes and does great harm to both human society and natural ecosystems.Agricultural GHG emissions,mainly in the form of methane(CH4)and nitrous oxide(N2O),are a significant source of GHGs,accounting for～14％ to-tal global GHGs(Zhang et al.,2022).
