“…Food security has been defined as a situation when food is physically and economically available for all people to meet their dietary needs for a healthy life [1]. Nowadays, food security has become a global issue as two-thirds of the population will live in cities in the near future [2][3][4][5][6], on the other hand, farming business has to face declining farmland conversion [7][8][9][10], a loss of farmland ownership [11][12][13][14], a lack in rural development [15,16], and unstable farming productivity due to climate changes [17][18][19][20]. Therefore, the compliance of food supply and demand should be carefully monitored to avoid declining nutrition and the poor health of humankind.…”

Food security has become one of the global challenges; therefore, monitoring food consumption is required. As food consumption is a resultant of food availability at an affordable price, food expenditure actually is a key indicator to assess food security policy. Particularly, the link of food expenditure with socio-economic factors based on the perspective of spatial connectivity should be understood as nowadays food supply and demand between regions are increasingly connected. This study aims to define socio-economic driving factors of food expenditure that considering spatial connectivity between provinces in Indonesia. Data of household food expenditure and socio-economic factors by province including urbanization level, economic growth, gross domestic regional product (GDRP) per capita, poverty severity index, and unemployment rate were used. The preliminary test on the spatial correlation of food expenditure showed a significant result; thus, a spatial regression approach was employed. The results showed that declining food expenditure did not simply indicate increasing prosperity. Larger income disparity among the poor has become crucial to detect lower food expenditure caused by a lack of income. In addition, the increasing unemployment rate was followed by increasing food expenditure. Despite economic growth, increasing GDRP per capita and urbanization contributing to declining food expenditure, both poverty and unemployment are the main issues that threaten household's ability to afford food. Furthermore, the effect of food expenditure in the neighboring region is also significant, but it shows a contradictory relationship as food expenditure in a region is decreasing when food expenditure in its neighbors is increasing, and vice versa. Therefore, reducing disparities in economic growth, GDRP per capita, urbanization, poverty, and unemployment rate between provinces is also crucial to support more equal food expenditure as well as to achieve the second goal of SDG's (Sustainable Development Goals) in improving food security.

“…Therefore, many young adults go out working and leave the elderly at home to avoid the risk of losing the land use rights. Obviously, this type of rural surplus labour transfer will cause coarse tillage of the cultivated land, decline of multiple crop indexes, decrease in sown area of grain, deterioration of ecological environment, empty villages and many other serious problems, which will greatly decrease the utilization efficiency of cultivated land (Gao et al, 2017;Li, Wu, Huang, Sloan, & Skitmore, 2017). On the contrary, some other studies showed that large-scale rural labour transfer can improve the utilization efficiency of cultivated land: on the one hand, rural labour force transfer can enhance the circulation of cultivated land, promoting the scale operation of cultivated land and agricultural productivity (Feng, 2008;Huang, Zhu, Deng, & Rozelle, 2005;Tan, Heerink, Kruseman, & Futian, 2008); on the other hand, the transfer of rural labour force can optimize the production structure of cultivated land, facilitating the application of advanced agricultural technologies (McCarthy, Carletto, Davis, & Maltsoglou, 2006).…”

The relationship between rural labour transfer and cultivated land use has always been a hot topic in academic field and government management. Here, by using the large‐scale survey data of 1,868 farmers from 37 villages in Jianghan Plain and the low‐hill areas in southeastern Hubei province, we investigated the relationship between rural labour force transfer and decision‐making in cultivated land use from the perspective of terrain heterogeneity. The findings indicate that under different terrain conditions, there are significant differences in the decision‐making of farmers concerning cultivated land use, leading to different land use efficiencies in different areas. Specifically, rural labour force transfer enhances land use efficiency in plain areas; however, it does not affect that in the low‐hill areas. In addition, we found that in the plain areas, improving the quality of rural household labour can increase the cultivated land use efficiency, while in low‐hill areas, enhancement of geographical accessibility is the key to improving land use efficiency.

“…Cultivated land has multiple functions that include production, spatial bearing capacity, and environmental protection, and is a fundamental guarantee of national food security and social stability [1][2][3][4]. For a long time, with the rapid development of industrialization and urbanization and the impact of global climate change, the limited cultivated land resources have been under considerable pressure in China, which poses a great threat to food security and the ecological environment [5][6][7][8][9][10]. Food is the primarily need of people, and how to make use of limited cultivated land resources to guarantee food for nearly 1.4 billion people is a realistic problem in China.…”

Cultivated land productivity is a basic guarantee of food security. This study extracted the multiple cropping index (MCI) and most active days (MAD, i.e., days when the EVI exceeded a threshold) based on crop growth EVI curves to analyse the changes and potential characteristics of cultivated land productivity in Jiangsu Province during 2001-2017. The results are as follows:(1) The MCI of 83.8% of cultivated land remained unchanged in Jiangsu, the cultivated land with changed MCI (16.2%) was mainly concentrated in the southern and eastern coastal areas of Jiangsu, and the main cropping systems were single and double seasons.(2) The changes in cultivated land productivity were significant and had an obvious spatial distribution. The areas where the productivity of single cropping system changed occupied 67.8% of the total cultivated land of single cropping system, and the decreased areas (46.5%) were concentrated in southern Jiangsu. (3) For double cropping systems, the percentages of the changed productivity areas accounting for cultivated land were 82.7% and 73.3%. The decreased areas were distributed in central Jiangsu. In addition, the productivity of the first crop showed an overall (72%) increasing trend and increased areas (40.8%) of the second crop were found in northern Jiangsu. (4) During 2001-2017, cultivated land productivity greatly improved in Jiangsu. In the areas where productivity increased, the proportions of cultivated land with productivity potential space greater than 20% in single and double cropping systems were greater than 60% and 90%, respectively. In the areas where productivity decreased, greater than 25% and 75% of cultivated land had potential space in greater than 80% of the single and double cropping systems, respectively. This result shows that productivity still has much room for development in Jiangsu. This study provides new insight for studying cultivated land productivity and provides references for guiding agricultural production.
