This study reviews China＇s food security prospects and their implications, focusing on international trade in the coming decade. The results show that China＇s policies for ensuring food security will be enhanced and China will move to sustainable agriculture. Most studies anticipate that China will increase its food and feed imports in the coming decade. China＇s overall food self-sufficiency is likely to fall from 94.5% in 2015 to around 91% by 2025. The greatest increases in imports are likely to be soybean, maize, sugar, and dairy products. However, within the production capacity of the major exporting countries and of many food-importing developing countries, China＇s additional imports of 3 to 5% of its total food consumption in the coming decade are unlikely to threaten global food security. Indeed, the projected imports of feed and several foods could provide opportunities for many exporting countries to expand their production and save global resources.展开更多

This study examines the impacts of migration on left-behind family members’ food consumption and nutrient intake, particularly in remote rural areas in China. Based on household survey data collected from 611 smallholder rubber farmers in Xishuangbanna Dai Autonomous Prefecture of southwestern China, the empirical results suggest that the migration of family members contributes to improving household net income, whereas it negatively affects left-behind family members’ consumption of grain and pork. Migration also leads to a decrease in left-behind family members’ nutrient intake. Surprisingly, the economic returns of farmers’ migration not only do not foster the transformation of household food consumption from a staple food-dominated dietary structure to one including more meat and dairy products but also reduce left-behind family members’ nutrient intake. This study adds to the literature on the impact of farmers’ migration. The findings have important implications for better understanding the impacts of migration on farmers’ livelihood and human capital development in rural China.展开更多

Using seven unique waves of panel data collected between 1999 and 2012 in China, we show that Bt cotton adoption has not only caused a reduction of the mean value of pasticide use, but also a reduction of the standard deviation of pesticide use. We conclude that Bt technology adoption has also contributed to the stability of pesticide use in cotton production. We believe that this contribution is theoretically and practically relevant because of the long length of our unique dataset.展开更多

Based on household survey data collected from 611 smallholder rubber farmers in Xishuangbanna Dai Autonomous Prefecture of southwestern China, the empirical results suggest that the migration of family members contributes to improving household net income, whereas it negatively affects left-behind family members’ consumption of grain and pork. Migration also leads to a decrease in left-behind family members’ nutrient intake. Surprisingly, the economic returns of farmers’ migration not only do not foster the transformation of household food consumption from a staple food-dominated dietary structure to one including more meat and dairy products but also reduce left-behind family members’ nutrient intake. This study adds to the literature on the impact of farmers’ migration. The findings have important implications for better understanding the impacts of migration on farmers’ livelihood and human capital development in rural China.

文摘Understanding the factors behind apple farmers’willingness to pass on the management of their farms to their descendants is crucial to the continuity of apple production.Due to the high specificity of the human capital,physical assets,land assets,and geographical location in apple production,this study used a binary logistic regression and a mediating effect model to explore the impact of asset specificity on farmers’intergenerational succession willingness of apple management(FISWAM)and to examine the mediating effects of loss aversion in the impact of asset specificity on the FISWAM.The results showed that about 18.68%of the respondents expressed willingness to transfer their apple business between generations,and the FISWAM was generally weak.In addition to the negative impact of geographical location specificity(GLS),human capital specificity(HCS),physical assets specificity(PAS),and land assets specificity(LAS)can enhance the FISWAM.Loss aversion plays a partial mediating role in the impact of PAS,LAS,and GLS on the FISWAM.

文摘Global tea consumption has risen significantly alongside rapid expansion of international trade in recent years.However,few studies have systematically examined the relationship among the major tea markets worldwide.Using weekly data from 2012-2019,this study empirically analyzed the price series of the world’s major black tea auction markets.The estimation results showed that these markets are connected,even though heterogeneities vary.This finding holds not only for regional markets but also for international markets.The findings offer important implications for tea-producing countries with millions of smallholder farmers.

文摘Even though the impact of Bacillus thuringiensis （Bt） cotton on pesticide use has been well documented, all previous stud- ies focus on the mean value of pesticide use. Using seven unique waves of panel data collected between 1999 and 2012 in China, we show that Bt cotton adoption has not only caused a reduction of the mean value of pasticide use, but also a reduction of the standard deviation of pesticide use. We conclude that Bt technology adoption has also contributed to the stability of pesticide use in cotton production. We believe that this contribution is theoretically and practically relevant because of the long length of our unique dataset.
文摘With the rapid development of China’s economy,Chinese people tend to eat foods rich in fat,sugar and protein.This change in dietary pattern has brought double challenges to China’s sustainable development of environment and human health.So it has become urgent for the nation to shift to a healthy and sustainable dietary pattern.Based on the China Health and Nutrition Survey database,this study used K-means cluster analysis to classify China’s existing dietary patterns into quasi-southern,quasi-northern and quasi-western patterns.Two alternative recommended dietary patterns,Chinese dietary and planet health patterns,were selected to compare the effects of environment and health.The results show that a shift from the three existing dietary patterns to two alternative dietary patterns could enhance sustainable development of environment,especially for the quasi-western pattern shifting to the planet health pattern.Also,a shift would have of great benefits for human health,effectively reduce the relative risks of diseases such as hypertension,type 2 diabetes and coronary heart disease.The greatest benefits would come from shifting the quasi-western pattern benefits to one of the two alternative dietary patterns in terms of environment effects,and the quasi-southern pattern benefits most in terms of health effects.Shifting to the planet health pattern is more effective than the Chinese dietary pattern both in environment and human health.This paper provides policy recommendations to vigorously advocate dietary balance,scientifically promote dietary patterns,and change consumer dietary behavior.

文摘Background:Grasslands provide a wide variety of ecosystem services that contribute to human wellbeing.While an increasing number of studies are evaluating the monetary value of grassland ecosystem services,most of them focus on specific grassland ecosystem services at regional or local scales,and they use different assessment methods.Methods:This paper provides a comprehensive assessment of the economic value of global grassland ecosystem services based on a meta-analysis of 702 observations from 134 primary studies.Results:The economic values of different ecosystem services cover a wide range of grassland types,regions,and estimation methods.The annual economic value per hectare ranges from$3955 for semidesert grasslands to$5466 for tropical grasslands.On average,regulating services have the highest value,which is approximately four times that of provisioning services or approximately eight times that of food supply services.Several factors impact the estimated ecosystem service values,including the evaluation method,source and year of publication,and study site.The results indicate that the annual economic value of global grasslands exceeds$20.8 trillion.Conclusions:The findings of this study not only provide useful information for understanding the economic value of various ecosystem services associated with different types of grasslands but also have important policy implications for the ecological conservation of grassland globally.
