Employing an endogenous switching regression model, we investigate the drivers underlying the adaptations made by farm households and their impacts on crop net incomes for adopters and nonadopters, based on a large panel survey data set across the major grain‐producing provinces in China. The results show that: (i) access to public climate information and technical or physical support increases the likelihood that farmers adapt to climate change by undertaking irrigation and/or drainage measures; and (ii) decisions to adapt increased crop yield, but they did not significantly increase crop profit margins. This point appears to have been ignored by previous studies. Based on these new empirical results, the paper suggests that government should continue to provide climate information and various types of supports to improve farmers’ adaptation abilities and help to reduce the levels of factor input by, for example, substituting organic for chemical fertiliser inputs. Such government‐led policies should be supported alongside the implementation of domestic agricultural supply‐side reform.

“…There are multiple approaches being reported to address such relations. For example, survey methodology is helpful to collect first‐hand information of how drought has affected crop yields and how farmers adapted to drought (Chen et al, ; Huang et al, ; Wang et al, ; Yan et al, ). Empirical models have been applied to analyze the statistical relations among meteorological factors and yields (Huang et al, ; Qin et al, ; Zhang & Huang, ; Zhang et al, ).…”

Assessing the Impacts of Extreme Agricultural Droughts in China Under Climate and Socioeconomic Changes

Agricultural food production in China is deeply vulnerable to extreme droughts. Although there are many studies to evaluate this issue from different aspects, comprehensive assessments with full consideration of climate change, crop rotations, irrigation effects, and socioeconomic factors in broad scales have not been well addressed. Considering both the probability of drought occurrence and the consequential yield losses, here we propose an integrated approach for assessing past and future agricultural drought risks that relies on multimodel ensemble simulations calibrated for rice, maize, and wheat (RMW) in China. Our results show that irrigation has reduced drought‐related yield losses by 31 ± 2%; the largest reductions in food production were primarily attributable to socioeconomic factors rather than droughts during 1955–2014. Unsustainable water management, especially groundwater management, could potentially cause disastrous consequences in both food production and water supply in extreme events. Our simulations project a rise of 2.5~3.3% in average rice, maize, and wheat productivity before 2050 but decrease thereafter if climate warming continues. The frequency of extreme agricultural droughts in China is projected to increase under all examined Representative Concentration Pathway (RCP). A current 100‐year drought is projected to occur once every 30 years under RCP 2.6, once every 13 years under RCP 4.5, and once every 5 years under RCP 8.5. This increased occurrence of severe droughts would double the rate of drought‐induced yield losses in the largest warming scenario. Policies for future food security should prioritize sustainable intensification and conservation of groundwater, as well as geographically balanced water resource and food production.

“…Moreover, rice farmers in China often adjust their farm management practices (e.g., reseeding, fixing, and cleaning seedlings) in response to extreme weather events such as drought and flood (Huang et al, 2015), which can help to stabilize production.…”

Core Ideas Improving crop yield stability has become even more important with climate change. Rice yield stability was significantly increased in most provinces in southern China. Continuous efforts are needed to maintain rice yield stability in southern China. Improving yield stability is an important objective of agricultural progress. This study was conducted to evaluate the trends of rice (Oryza sativa L.) yield stability in southern China. Rice yield data during a 67‐yr period for 12 provinces in southern China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Sichuan, Yunnan, and Zhejiang) were collected from the World Rice Statistics database (from 1949 to 2013) and the database of the National Bureau of Statistics of China (for 2014 and 2015). Relative yield residuals for each province were calculated and indicated that rice yield stability significantly increased in 10 of the 12 provinces, with only Guangdong and Guizhou not showing an increase during this 67‐yr period. We believe that a stable increase in rice production is achievable in southern China with the continuous efforts to develop new cultivars, improve crop management practices, and strengthen public services such as releasing disaster information and using technical experts.
