Did Household Income Loss Have an Immediate Impact on Animal-Source Foods Consumption during the Early Stage of the COVID-19 Pandemic?

The outbreak of COVID-19 in 2020 caused extensive impact on household income and foods consumption. However, little attention has been paid to the immediate impact of income loss on animal-source foods consumption in the early stage of the COVID-19 pandemic. This paper aims to narrow this gap, and a total of 1301 valid samples of household food consumption surveys in Wuhan and Nanjing were obtained through specially designed online questionnaires.

Pathways to food insecurity: Migration, hukou and COVID-19 in Nanjing, China.

The COVID-19 pandemic has issued significant challenges to food systems and the food security of migrants in cities. In China, there have been no studies to date focusing on the food security of migrants during the pandemic. To fill this gap, an online questionnaire survey of food security in Nanjing City, China, was conducted in March 2020.

Impacts of community-level grassroots organizations on household food security during the COVID-19 epidemic period in China.

Purchasing food via community-level grassroots organizations was a new pattern of food patronage for Wuhan residents during the COVID-19 lockdown in 2020, but little attention was paid to it. The study examined the relationship between community-level grassroots organizations and household food insecurity based on an online survey of household food insecurity in Wuhan in March 2020. The study found that problems in all three domains of food insecurity including food anxiety, insufficient quality and inadequate quantity existed but were uneven.

Emergency food supplies and food security in Wuhan and Nanjing, China, during the COVID-19 pandemic: Evidence from a field survey.

Motivation: Detailed empirical work on the impact of the COVID-19 pandemic on food security is scant. Local management of food security has received little attention.

Purpose: This article describes emergency food policies in Wuhan and Nanjing, China during lockdown in 2020 and their implications for household food security in the two cities.

Factors determining household-level food insecurity during COVID-19 epidemic: a case of Wuhan, China.

Background: In coping with the coronavirus disease 2019 (COVID-19) epidemic, cities adopted social isolation and lockdown measures; however, little is known about the impacts of these restrictions on household food security.

Objective: This study provides a timely assessment of household food insecurity (HFI) in the Chinese city of Wuhan during the COVID-19 epidemic period and also investigates its determinant factors.

Design: We collected valid data on food insecurity from 653 households in Wuhan via an online questionnaire in March 2020.

Concentration of heavy metals in vegetables and potential health risk assessment in China.

Food safety is an important issue in the world. This study assessed the health risk for the Chinese public when consuming vegetables grown in China, based on 1335 data records from 220 published papers during 2007-2016. The results showed that the average of Pb, Cd, and Hg concentration in vegetables was 0.

Carbon emissions from land-use change and management in China between 1990 and 2010.

China has experienced enormous changes in land use in recent decades, which are largely driven by its unparalleled economic development. We analyze changes in vegetation and soil carbon storage between 1990 and 2010 resulting from combinations of land-use category conversion and management. Results demonstrate a major decline in grasslands (-6.

Identification of Potential Sources of Mercury (Hg) in Farmland Soil Using a Decision Tree Method in China.

Identification of the sources of soil mercury (Hg) on the provincial scale is helpful for enacting effective policies to prevent further contamination and take reclamation measurements. The natural and anthropogenic sources and their contributions of Hg in Chinese farmland soil were identified based on a decision tree method. The results showed that the concentrations of Hg in parent materials were most strongly associated with the general spatial distribution pattern of Hg concentration on a provincial scale.

Impact of Soil Heavy Metal Pollution on Food Safety in China.

Food safety is a major concern for the Chinese public. This study collected 465 published papers on heavy metal pollution rates (the ratio of the samples exceeding the Grade II limits for Chinese soils, the Soil Environmental Quality Standard-1995) in farmland soil throughout China. The results showed that Cd had the highest pollution rate of 7.

Assessment of arsenic (As) occurrence in arable soil and its related health risk in China.

Arsenic (As) is a major global environmental pollutant due to its high toxicity on human and animal health. This study collected 427 relevant papers to study As concentrations in Chinese arable soil and evaluate the health risk of exposure to As for humans. Results showed that the average of As concentration was 9.

Assessment of cadmium (Cd) concentration in arable soil in China.

Cadmium (Cd) concentration in arable soil has drawn broad public attention due to its direct effect on Cd concentration in food. However, there have been few studies of surveying Cd accumulation on the national scale in China. This paper collected 486 studies of Cd concentrations in Chinese arable soil.

[Spatial distribution and accumulation of heavy metal in arable land soil of China].

Based on the domestic and foreign published papers about soil heavy metal contents, the present study explored the spatial variations of heavy metal contents in agricultural soil in China. Totally, 173 studies on soil Pb, 138 on Cd, 156 on Cu, 139 on Zn and 140 on Cr were collected. Firstly, the abnormal values were selected and removed, then the spatial distributions were obtained through Kriging method and the average values in the provinces were calculated.

[Spatial pattern evolution of carbon emission intensity from energy consumption in China].

Using Theil index and spatial autocorrelation analysis methods, the characteristics, regional disparity and spatial pattern evolution of carbon emission intensity from energy consumption were analyzed on national, regional and provincial level from 1999 to 2007 in China. The results indicate that: (1) total energy carbon emission in China has increased from 0.91Gt in 1999 to 1.

[Application of spatial autocorrelation analysis to the COD, SO2 and TSP emission in Jiangsu province].

Spatial autocorrelation is an effective tool of spatial statistics, which is used to disclose the spatial structure of regional disparity. There are two different scales to measure regional spatial dependence: global spatial autocorrelation and local spatial autocorrelation. Based on environmental data of 13 cities in Jiangsu province from 1990 to 2006, the regional disparity of COD, SO2 and TSP emission was discussed by using spatial autocorrelation analysis methods.

[Impact of rural land market on farm household's behavior of soil & water conservation and its regional difference: A case study of Xingguo, Shangrao, and Yujiang County in Jiangxi province ecologically vulnerable districts].

The paper analyzed the farm households' decision-making progress of soil & water conservation and its two-stage conceptual model. It also discussed the impacts of rural land market on the farm households' behavior of soil & water conservation. Given that, the article established models for the relations between the land market and soil & water conservation, and the models' parameters were estimated with Heckman's two-stage approach by using the farm household questionnaires in Xingguo, Shangrao and Yujiang counties of Jiangxi province.
