Since the reform and opening-up in 1978, a remarkable achievement has been made in poverty reduction in China. Many previous studies have analyzed the poverty reduction effects of economic growth, fiscal expenditure, education levels, information technology, urbanization, foreign trade, industrial development and other factors. As a bridge between production and consumption, the agricultural products circulation industry has an important role on the income growth of rural residents. However, the construction level of China’s agricultural products circulation infrastructure lags behind, resulting in a decline in the efficiency and quality of agricultural products supply, and farmers are also facing the embarrassing situation of increasing production without increasing income. Therefore, in this study, we selected the China’s provincial panel data from 2003 to 2017 to analyze the effect of agricultural products distribution infrastructure in narrowing the income gap between urban and rural residents and poverty reduction in China. First, we review the extant literature and elaborate the poverty reduction path of agricultural products circulation industry; secondly, we build models step by step and select nine variables; lastly, we carry out regression analysis on the overall poverty reduction effect of China’s agricultural products circulation industry, the poverty reduction effect of internal factors of agricultural products circulation industry and regional spatial heterogeneity with Stata software. Our results showed that the development level of the agricultural products circulation industry and the degree of opening-up have significant positive effects on narrowing the income gap between urban and rural residents and poverty reduction varied, with different regions in China. Among all the internal factors of development of agricultural products circulation industry in poverty reduction, the core explanatory variable is the investment in agricultural products circulation infrastructure with the largest poverty reduction effect, followed by the human capital, informatization level and number of employees of the agricultural products circulation industry, and the poverty reduction effects of the four internal development factors have had significant regional differences in China. Our findings further complement the internal mechanism of agricultural product circulation infrastructure on poverty reduction in China, suggest that we should apply appropriate strategies and give priority to the internal development factor of the agricultural product circulation industry, with the largest poverty reduction effect according to local conditions in different regions, and so be better able to achieve the targeted poverty alleviation and offer insights for the rural poverty reduction in other countries, especially in the developing countries.
In light of the increasing global food crisis, this study concentrated on the complex causality of sustainable food security in China. In the context of the agricultural green transformation, a comprehensive evaluation system of agricultural green development is constructed on China Yearbooks’ economic data and agricultural greening indices from 2012 to 2020. In addition, the coupling coordination degree model and fuzzy-set quantitative analysis are used to describe the path evolution of sustainable food security development in China. The results revealed that: (1) the comprehensive assessments were increased in recent years, and high score regions changed apparently, from the periphery to midland; (2) China’s green development and agricultural economic potential are currently in a transitional phase from basic to moderate synergy, and the higher coordinated degree is allocating to mid and southern areas during this period, and all of them keeps growing as well; and (3) under modern food security framework, the emphasis of China has gradually shifted from grain output and subsidy policies to high resources utilisation and human capital accumulation. Thus, China’s agricultural green transformation and sustainable food security are mutually reinforcing.
In a response to the appeal for securing the rice production efficiency to achieve the United Nations Sustainable Development Goals, we adopted a geographic detector model to investigate the spatiotemporal evolution trajectory and driving forces of the rice production in the world’s largest rice-producing country, China. We have analyzed the spatiotemporal evolution features and aggregation patterns of county rice production efficiency based on panel data of 122 counties in Hunan Province, one of the main grain production provinces in China, from 2006 to 2018. Our findings indicate: (1) Hunan Province’s rice production in three counties (i.e., Taoyuan, Liling, and Anren) showed the highest efficiency; there were pronounced regional variances in rice productivity which results in a sharp and rapid shrink of the range of rice productivity, (2) financial investments in agriculture, forestry, and water resources, as well as per capita disposable income of farmers, were the main determinants of the spatiotemporal variation in rice production efficiency, (3) the spatiotemporal divergence of rice production efficiency at the province level was U-shapedly, influenced by the share of secondary industry in GDP; the southern Hunan region received the biggest contribution from farmers in terms of disposable income per person at the regional level. Overall, theoretically, this study offers fresh evidence for regional optimization of rice and other grain production from a novel integrative approach of the geospatial and the land resource preservation. Practically, it provides feasible guidance for the high-quality development of grain production in China, which may also help eradicate hunger and attain sustainable grain production all over the world.
The management of water resources requires a correct understanding of the simultaneous management of food and energy resources. The framework of water–food–energy correlation with the approach of sustainability of resources and uses analyzes the combined management and exploitation of water, food, and energy resources with the help of scenario planning. In addition to sustainability concepts, environmental costs such as the emission of carbon dioxide from fossil fuels and its impact on the environment are also discussed. In this research, according to the five defined indicators and based on the potential of using solar energy and the possibility of exploiting renewable energy sources such as solar energy, various management scenarios have been developed. After examining the virtual water management model developed in the Hunan basin as a case study, the development of the water–food–energy nexus model and its calibration, and four scenarios including improving water use efficiency, energy saving, increasing food productivity, and nexus sustainability were developed. The results showed that the nexus strategy can provide sustainability goals according to the weight of each component. After the combined scenario, improving the efficiency of water consumption can be the component with the highest priority in the decision-making model in dry areas.
