Abstract
Developing tailored emission reduction strategies and estimating their potential is crucial for achieving low-carbon rice production in a specific region, as well as for advancing China’s dual carbon goals in the agricultural sector. By utilizing water-saving and drought-resistant rice (WDR) with enhanced water and nitrogen utilization efficiency, the mitigation strategies were constructed for rice production systems, and their potential for emission reduction was estimated in the southern rice propagation base of Hainan Province. This study revealed that the implementation of a reduction strategy, which involves dry direct seeding and dry cultivation, combined with a 53% reduction in nitrogen fertilizer, can effectively synergize the mitigation of methane (CH4) and nitrous oxide (N2O) emissions from rice paddies. Compared with traditional flooded rice cultivation, this integrated approach exhibits an impressive potential for reducing net greenhouse gas (GHG) emissions by 97% while simultaneously doubling economic benefits. Moreover, when combined with plastic film mulching, the strategy not only sustains rice yields but also achieves a remarkable emission reduction of 92%, leading to a fourfold increase in economic benefits. Our study provides a comprehensive low-carbon sustainable development strategy for rice production in the southern rice propagation base of Hainan Province and offers valuable insights for researching GHG emissions in other regions or crops. These emission reduction pathways and the assessment method could contribute to the realization of low-carbon agriculture.
