Climate-smart agriculture is guided by three main goals: increased productivity, enhanced resilience (climate change adaptation), and reduced emissions (climate change mitigation). Early mature crop varieties have been promoted to minimize the impact of climate change and extreme weather events on farming activities. This study examined the effects of adopting early mature rice varieties on agricultural productivity, climate change adaptation, and mitigation. Data came from a cross-sectional sample of 1396 rice farmers in Hubei, China. Productivity was measured via mean rice yield. Production risk (variance of yield) and downside risk (skewness of rice yield) were used as proxies for adaptation. Life cycle assessment was used to calculate the greenhouse gas emissions of rice production. Results indicated that adopting early maturing varieties significantly increased mean rice yield and reduced production risk, downside risk, and greenhouse gas emissions. Altogether, this study provided evidence that using early maturing varieties positively contributed to the three goals of climate-smart agriculture. Our findings provide insight into formulating future policies and programs promoting agricultural sustainability and climate resilience in China and other developing nations in the region.

Genetically modified insect-resistant cotton has been recognized as a potential technological means of adapting to climate change, but much remains unknown about how it affects factor efficiency. Using panel data for China from 1993 to 2020, this study explored the impact of genetically modified insect-resistant cotton on the factor efficiency of cotton production under climate change. We found that the adoption of genetically modified insect-resistant cotton significantly increases the output elasticity of pesticides while diminishing that of fertilizer, but has no effect on labor. This is mainly because it reduces the input of pesticides, which is otherwise expected to increase as a result of pest outbreaks caused by climate change. In contrast, it increases fertilizer input and thus reduces the output elasticity of fertilizer. Additionally, the effects on pesticide and fertilizer elasticity were weaker in the Yangtze River basin and northwest China, but stronger in the Yellow River basin. These findings provide a better understanding of how agricultural production factor efficiency responds to the adoption of adaptive behaviors under climate change. They can also serve as a reference to assist farmers in evaluating the effectiveness of adaptive behaviors and optimizing resource allocation for climate change adaptation.
