Influence of labor migration on rural household food waste in China: Application of propensity score matching (PSM).

Food waste has emerged as a critical global concern, with households identified as major contributors to this pressing issue. As the world grapples with sustainability challenges, addressing food waste in the context of rural labor migration is crucial for achieving broader sustainable development goals. However, there is still limited research regarding the relationship between labor migration and food waste. We utilized propensity score matching to analyze cross-sectional data collected from 1270 rural households in China. Labor migration led to significant increases of 37% in overall food waste and 35% in plant-based food waste, respectively. Furthermore, households with labor migration exhibited 29%, 31%, and 30 % higher energy, protein, and carbohydrate waste, respectively, compared to non-migration households. Regarding micronutrients, migration led to a 39% increase in iron waste, a 42% increase in zinc waste, and a 47% increase in selenium waste. The results of the categorical analysis indicate variations in the impact of labor migration on food wastage within rural households. Food wastage in rural households with chronic illness patients responds differently to labor migration. Moreover, labor migration predominantly affects households without courier services in villages, where dietary diversity plays a significant role. Understanding these variations is essential for crafting targeted interventions and policies to address food waste in different rural contexts. The policy implications of our study are crucial for addressing food waste and advancing sustainable development in rural China, where labor migration plays a significant role.

Solid Waste Management Practices and Challenges in Rural and Urban Senior High Schools in Ashanti Region, Ghana.

This study is aimed at comparatively analyzing solid waste management practices and challenges in urban and rural senior high schools in the Ashanti region of Ghana. Multiple sampling techniques (simple random, stratified sampling, convenience sampling, stratified proportionate sampling, etc.) were used to sort 370 samples. Independent Sample t-test was used to compare solid waste management practices in rural and urban senior high schools. Mean and standard deviation were further used to examine the challenges the schools faced in managing waste. The study found that both rural and urban senior high schools had waste management practice systems in place but they were dissimilar. However, in both urban and rural senior high schools, the issue of inadequate resources for effective waste management was ubiquitous challenge confronting both set of schools in managing waste. Further, while poor student attitude towards waste management was a major constraint for rural schools, the urban schools had a challenge in terms of poor waste collection routine. Formation of environmental education clubs by school authorities among student can be a sine qua non for effective waste management practices among students, particularly for the rural folks. Again, waste management policies by the District Assemblies should not be exclusive to only the communities, as senior high schools have been experiencing population explosion with the introduction of the free senior high school policy.

Differences and determinants for polluted area, urban and rural residents' willingness to hand over and pay for waste mobile phone recycling: Evidence from China.

Currently, China has the largest generation volume of waste mobile phones (WMPs), but the recycling rate is still negligible. How to improve the willingness to hand (WTH) over to formal recycling channels and willingness to pay (WTP) have become the most core problems in the e-waste recycling industry. As the important link between WMPs generation and collection, the residents' role and function are attracting more and more attention. Thus, this study is designed to identify the determinants of the residents' WTH and WTP for WMPs through the contingent valuation method (CVM). At the same time, it will explore the current existing gaps from the urban and rural residents. Especially, this study also considers Guiyu Town as one special rural region for understanding the differences with other regions. The results show that the respondents generally have the relatively lower knowledge and cognition on WMPs recycling. Only 9.4% respondents are satisfied with the current government's management of WMPs. Personal information leakage is an important reason for low WTH. The WTH of Guiyu, urban and rural respondents were 51.3%, 45.9% and 41.2%, respectively; while their WTP were 46.80%, 31.70% and 37.80%, respectively. Finally, it is estimated that their WTP values were 18.75 ($2.81), 16.14 ($2.42) and 15.85 ($2.38) RMB per unit, respectively. The demographic variables, cognition and attitude are important factors on all residents' WTH and WTP. Meanwhile, it is indicated that if owning higher WTH, the residents will trend to higher WTP. Especially, the WTH and WTP of Guiyu residents are higher than other residents.

Spatial-temporal and structural differences in the carbon footprints embedded in households food waste in urban and rural China.

Household food waste (HFW) accounted for about 66% of global food waste's total carbon footprints (CF). Based on China's macro-panel food consumption data, this paper measures the urban-rural and provincial differences in the HFW CF from scale, structure, and temporal-spatial evolution perspectives. The results indicate that HFW and CF continue to grow, and the total CF and per capita HFW in urban households are higher than in rural households. The structural differences between urban and rural HFW CF vary significantly over time and spaces, which reflected that rural households in the southeastern coastal areas have higher per capita HFW CF than urban in 2019. The research results help to clarify the distribution and evolution pattern of HFW CF in China and offer new ideas for the differentiated governance of CF reduction in the food system.

An Analysis of the Factors behind Rural Residents' Satisfaction with Residential Waste Management in Jiangxi, China.

With the increasing environmental and health problems caused by residential solid waste (RSW), upgrading waste disposal services has become a key priority in rural areas of developing countries. Waste disposal services can be improved by incorporating the end-user evaluation of the services and the infrastructure. This study aims to analyze the respondents' satisfaction with waste disposal services and infrastructure in rural China, which has not been well documented in the previous literature. For this purpose, we applied the ordered probit model on survey data of 1064 rural residents of Jiangxi, China. In two separate models, two independent variables, i.e., users' ranking of waste disposal management services and waste disposal management infrastructure, were regressed on five sets of policy, personal, social and demographic, environmental, and village characteristics of the respondents. Our results show that rural residents have relatively high satisfaction (level four out of five) with RSW services. We found a significant correlation between all five investigated characteristics (personal, social and demographic, environmental, and village characteristics) and respondents' satisfaction with RSW management. However, the correlation differs in magnitude and direction among different respondent groups, where gender, minority status, the sanitary condition of household toilets, and treatment of toilet waste at the village level have the largest influence on satisfaction. It was found that male respondents, ethnic minorities, residents with non-farming status, and respondents with more sanitary household toilets have higher satisfaction levels. Our results provide crucial references for decision-makers to effectively promote the further optimization and improvement of rural waste disposal systems in the future.

A Critical Analysis of Indigenous Systems and Practices of Solid Waste Management in Rural Communities: The Case of Maseru in Lesotho.

The aims of this study were to understand and to do a critical analysis of the different indigenous systems and practices of waste management to inform waste management policy development in Lesotho. To achieve these aims, the objective was to assess community perceptions of the impact of the indigenous systems and practices of solid waste management on the environment and human wellbeing. A simple random sampling method was employed. The primary data were collected through observations and survey questionnaires that were distributed among the communities in the study areas. The sample size was 693 participants from a total estimated population of 6917 in May 2021 in the Matsieng, Koro-Koro and Rothe constituencies. The data were analysed quantitatively by using the International Business Management Statistical Package for Social Science version 25.0. The descriptive method was used to interpret the results. For validity, the interview questions were set towards answering the study research questions. For reliability, open- and close-ended questions were designed. The research clearly indicated that indigenous systems and practices are culturally accepted in areas lacking formal waste collection services by the local authorities. The tradition, culture, values, and belief of the communities play a major role in the systems and practices implemented. Although some people convert waste items into useful products, the practices of general disposal were often unsafe from the human wellbeing and environmental perspectives. In Lesotho, a lack of awareness about conservation and sustainable use of natural resources could be attributed to flawed education at the grassroots level in schools.

Effect of domestic solid waste disposal practices on quality of drinking water sources in some rural communities of Akwa Ibom State, Nigeria.

Poor waste disposal practices impinge on water quality. An assessment of the effect of domestic solid wastes disposal practices on microbial quality of drinking water sources was conducted in some rural communities of Akwa Ibom State, Nigeria. An ecological study design was adopted using quantitative methods and a multi-stage sampling technique for random selection of LGAs, communities, and households for the administration of questionnaires to 120 respondents within four communities. Microbiological analysis of water samples from various sources was also conducted. A total of 26 (43.3%) and 16 (26.7%) households in the coastal and upland areas respectively had waste disposal facilities, the remaining percentage dumped waste into rivers and nearby bushes. The majority of the coastal community dwellers defecate directly into water bodies or swamps due to a lack of faeces disposal facilities whereas all respondents in the upland areas had faeces disposal facilities though some were unimproved. The result of the microbial analysis showed that the coastal areas had a mean heterotrophic bacterial, coliform, and fungal count of 1.45(± 0.44) × 105 cfu/ml, 0.90(± 0.27) × 105 cfu/ml, and 1.75(± 0.50) × 105 cfu/ml while the upland areas had 1.34(± 0.55) × 105 cfu/ml, 0.65(± 0.36) × 105 cfu/ml, and 1.88(± 0.58) × 105 cfu/ml. There was no significant difference (P < 0.05) in microbial water quality between the coastal and upland areas besides the self-reported health problems. A moderate positive correlation was found between solid waste disposal practices and total bacterial count (r = 0.418**), and total coliform (r = 0.397**), P < 0.01. Most of the microorganisms isolated from drinking water in both settings were of public health importance. The result obtained from this study indicates very poor water quality in both settings. This implicates the poor solid waste disposal practices predominant in these communities and calls for immediate measures to secure the health of the rural community dwellers.

Determinants of Satisfaction with Solid Waste Management Services: A Central-Local Comparison in China.

The Chinese central government proclaimed a mandatory or demonstration waste separation policy in some cities or counties to manage the increasing amounts of generated waste since 2017. Many cities and regions have also begun to build waste separation management systems and institutions, and community managers have created waste management rules and provided separation management services under the guidance of local government. However, little is known about how these policies or services have performed and the degree of residents' satisfaction, especially regarding the central government. Therefore, the purpose of this study was to analyze the consequence of these policies using residents' community and national satisfaction levels with solid waste management services (SWMS) and their determinants. An online survey in 2021 showed that the overall satisfaction levels of communities and national SWMS are similar, but the differences between rural and urban regions are significant. Residents' satisfaction with community SWMS in urban regions was higher than national satisfaction, and the results in rural regions was contrary. The determinants of community and national satisfaction were also different and varied by region. To improve satisfaction, the government need to standardize basic management systems in different types of regions, gradually improve management services and institutions in rural areas and non-pilot cities and provide special services or facilities for less healthy residents.

Improved Water and Waste Management Practices Reduce Diarrhea Risk in Children under Age Five in Rural Tanzania: A Community-Based, Cross-Sectional Analysis.

Diarrhea remains a significant cause of morbidity and mortality among children in developing countries. Water, sanitation, and hygiene practices (WASH) have demonstrated improved diarrhea-related outcomes but may have limited implementation in certain communities. This study analyzes the adoption and effect of WASH-based practices on diarrhea in children under age five in the rural Busiya chiefdom in northwestern Tanzania. In a cross-sectional analysis spanning July-September 2019, 779 households representing 1338 under-five children were surveyed. Among households, 250 (32.1%) reported at least one child with diarrhea over a two-week interval. Diarrhea prevalence in under-five children was 25.6%. In per-household and per-child analyses, the strongest protective factors against childhood diarrhea included dedicated drinking water storage (OR 0.25, 95% CI 0.18−0.36; p < 0.001), improved waste management (OR 0.37, 95% CI 0.27−0.51; p < 0.001), and separation of drinking water (OR 0.38, 95% CI 0.24−0.59; p < 0.001). Improved water sources were associated with decreased risk of childhood diarrhea in per-household analysis (OR 0.72, 95% CI 0.52−0.99, p = 0.04), but not per-child analysis (OR 0.83, 95% CI 0.65−1.05, p = 0.13). Diarrhea was widely treated (87.5%), mostly with antibiotics (44.0%) and oral rehydration solution (27.3%). Targeting water transportation, storage, and sanitation is key to reducing diarrhea in rural populations with limited water access.

Exploring rural inhabitants' perceptions towards food wastage during COVID-19 lockdowns: Implications for food security in Pakistan.

The lessening of food wastage, specifically among nations where about half of its worldwide quantity is produced, has turned to be a mammoth challenge for environmental, social and economic sustainability, and represents one of the seventeen Sustainable Development Goals (SDG) within the Agenda 2030. The quantity of food being thrown away in spite of being in an edible condition has become alarming in middle and high income countries. The COVID-19 lockdown strategy, both at local and international levels, has expressively altered work, life and food consumption behaviors globally, directing to food wastage as a multi sectoral issue. Pakistan has no exception to such manifestations. The main objective of this study is to analyze the perceptions of rural people of Pakistan regarding food wastage during the COVID-19 pandemic. To evaluate whether behavior about food wastage among rural households varied or not during the pandemic, a descriptive survey was carried out using a self-administered questionnaire and 963 responses were selected for further empirical investigations. The findings of the study reveal that food waste actually decreased in spite of an increased amount of purchased food during the lockdown. Our results highlight that the effect of the pandemic has led to reduction in food wastage among rural respondents, an increased consciousness for the morals of food waste, and awareness of environmental impacts of food wastage. The conclusions of this study highlight that rural consumers of Pakistan are emerging with a new level of responsiveness about food wastage with possible positive impact on the environment in terms of decreased greenhouse gas (GHG) emission and other pollutants. The study findings imply that this pandemic time provides a suitable window to raise awareness about food wastage among rural as well as urban households while contemplating effective strategies to overcome the issue of food wastage in the country.

A three-pronged approach to waste composition determination.

Understanding solid waste composition has frequently been cited as one of the most valuable resources to those responsible for the proper management of solid waste. The unique contribution of this article lies in the fact that a waste characterisation study, conducted in a remote rural town in South Africa, was combined with an illegal dumping contents mapping and a household survey. This enabled researchers to gain a more thorough understanding of household waste management practices and challenges in this community, bridging the knowledge gap that is created when illegal dumping and household perceptions are omitted from waste characterisation studies in study areas where illegal dumping is an ongoing concern. The study therefore contributes to understanding the waste behaviour of households within the larger context of the town's waste management practices. Results indicate that, in order for municipalities to fully understand how to manage their waste, the contents of illegal dumping, where present, and household surveys should also be included in waste characterisation assessments.

Identifying the status and differences between urban and rural residents' behaviors and attitudes toward express packaging waste management in Guangdong Province, China.

With the rapid development of the express delivery industry, the environmental issues of express packaging waste (EPW) have gradually attracted public attention worldwide. As important participants, consumers' behaviors and attitudes will play a vital role in solving the problem. This study uses the conditional value method (CVM) to evaluate the differences in the attitudes and willingness to pay of urban and rural residents toward EPW in Guangdong Province, China. The results show that the respondents have limited knowledge of the recycling situation, relevant policies and environmental impacts of express delivery packaging, although more than 60% of respondents do think that there is a problem with excessive packaging. The low recycling rate for packaging materials is mainly attributed to the lack of recycling facilities and publicity on environmental issues. The differences between urban and rural residents are mainly over disposal methods, the views on excessive packaging and willingness to pay (WTP) for EPW. Finally, the WTP values of urban and rural residents choosing a "deposit" system are 1.58 ($0.24) and 1.79 yuan ($0.28) per piece, respectively, while the WTP values (for increased fees) are 0.64 yuan ($0.10) and 0.60 yuan ($0.09) per piece, respectively. The obtained results may serve as a reference for different regional responses to the promotion and improvement of EPW management in the future.

Household food waste in rural China: A noteworthy reality and a systematic analysis.

Economic development has improved people's daily diets in China, but food waste has increased significantly. China faces severe natural resource constraints, and reducing food waste is important for ensuring national food security. Based on 1634 survey samples from 28 provinces in China, this study assessed food waste in rural China and empirically analyzed the main factors affecting rural household food waste. The results showed that, on average, 1.67% of food is wasted per household each day in rural China. Food waste is greater in economically developed areas, such as East China. Empirical analysis showed that cooking utensils, preparing the right amount of food, religious beliefs, number of family members, average weight of family members, percentage of purchased grain in the total food consumption in 1 year, and total grain output are significantly related to rural household food waste.

Rural Residents' Awareness of Environmental Protection and Waste Classification Behavior in Jiangsu, China: An Empirical Analysis.

Achieving waste classification and environmental protection awareness assists in enhancing the rural ecological environment, improves the quality of the rural residents' life, and augments the rate of reusing resources within the rural setups. In order to study the factors influencing rural waste classification and environmental protection awareness, we conducted a project among rural residents of Jiangsu, China. We used both the logistic regression model and the ordinary least squares model to achieve the goals of this paper. Similarly, we found that the households' level of education influenced the rural residents' decision to classify waste and to protect the environment regarding whether a household consists of a village cadre; the availability of public waste collection facilities; the distance between households and the waste collection points; whether the waste is picked, assorted, and collected locally; and the cost of waste disposal. In light of all these factors, we recommended that the authorities should increase the rural residents' waste classification and environmental protection awareness. Also, through the local government, the national government should strengthen and sustain rural waste disposal funds. Finally, there should be stringent laws and regulations outlining the role of the rural residents regarding waste classification and environmental protection awareness.

Evaluation of conventional and alternative anaerobic digestion technologies for applications to small and rural communities.

The management of food waste has been considered an extremely important issue since the 1990s but finding efficient solutions for small and rural communities is still challenging. Anaerobic digestion (AD) may provide interesting opportunities in terms of carbon emissions and economic payback in the long term, but the choice of the correct technology and the spatial scale requires attention. The focus of this study is on a small rural municipality, which is selected as a case study to assess the environmental and economic sustainability of the application of two options for AD (a conventional and an alternative wet process) and two spatial scales (municipality and a consortium of municipalities). Both the AD configurations are examined in terms of biogas exploitation, through a combined heat and power generator, and in combination with a post-composting stage of the digestate. From economic and environmental perspectives, the consortium-scale application of the conventional wet process is expected to generate greater benefits in the long term, as it enables 80% more electric energy production and economic revenues/savings, and avoids carbon emissions. However, before selecting the technology, decision makers should consider the public acceptance of local communities (e.g., the susceptibility to the "not-in-my-backyard" syndrome), as the best technical-economical solution may not be the most appropriate to specific communities. The methodology developed in this paper and the discussion of the results will inform decision makers about how to identify the most appropriate alternative for their purposes.

Investigating Rural Domestic Waste Sorting Intentions Based on an Integrative Framework of Planned Behavior Theory and Normative Activation Models: Evidence from Guanzhong Basin, China.

The sorting of domestic waste is the most effective way to alleviate the problem of mass garbage accumulation around the villages of rural China. Farmers are the creators of rural domestic waste as well as the direct beneficiaries of effective waste management. However, few studies have been conducted on the psychological determinants of farmers' intentions to sort domestic waste. This paper applies planned behavior theory (TPB) and normative activation theory (NAM), to analyze the domestic waste sorting intentions of rural residents in Guanzhong, China. Based on the micro-data of 327 rural households in Guanzhong, structural equation models of the factors influencing farmers' domestic waste sorting intentions were estimated. The results demonstrate the following. (1) Farmers' attitudes, perceived behavioral control, and personal norms have significant positive direct impacts on their domestic waste sorting intentions, with personal norms having the greatest direct impact. (2) Subjective norms have no direct impact on farmers' domestic waste sorting intentions but do have an indirect impact on them through personal norms, behavioral attitudes, and perceived behavior control. This article increases scholarly understanding of the psychosocial determinants of the environmentally friendly behavioral intention to sort domestic waste. The study also provides academic and theoretical support to policy makers in implementing relevant policy recommendations.

Correlates of appropriate disposal of children's stools in Malawi: a multilevel analysis.

BACKGROUND: Management of children's stools is an important aspect of achieving open defecation free communities and reduction of diarrhea. However, information regarding individual- and community- level factors associated with safe child stool disposal in Malawi is limited. The current study aimed to assess the prevalence of safe child stool disposal and the associated individual- and community- level factors in Malawi. METHODS: The cross-sectional study used data from the 2015-16 Malawi Demographic Health Survey in which 6326 children aged under 2 years, nested within 850 communities, were analyzed. Individual- and community- level factors were tested for association with safe child stool disposal practice using multilevel logistic regression models. RESULTS: Results revealed that 85.6% of the women reported to have safely disposed of their children's stools. Women from households with improved sanitation had 36.0% greater odds of safely disposing of their children's stools compared with those from households with unimproved sanitation [(adjusted odds ratio (aOR): 1.36; 95% confidence interval (CI): 1.12-1.65). Further, women from communities with a middle (aOR: 1.62; 95% CI: 1.18-2.21) and high (aOR: 1.45; 95% CI: 1.14-1.84) percentage of educated women were more likely to have their children's stools safely disposed of than those from communities with a low percentage of educated women. Children's age, media exposure, and region were significantly associated with safe stool disposal. CONCLUSION: Both Individual- and community-level factors were revealed to be important factors for child stool disposal. Public health strategies designed to promote sanitation/safe child stools disposal need to conduct thorough community assessments to identify community-specific needs/barriers. Additionally, public health practitioners should take into consideration the geographical and wealth inequalities when designing programs aimed to improve safe child stood disposal.

Impact of Locational Choices and Consumer Behaviors on Personal Land Footprints: An Exploration Across the Urban-Rural Continuum in the United States.

Land is a scarce resource. We develop consumption-based land footprints (CBLF) for urban and rural U.S. residents to evaluate new levers for reducing land-demand by combining (1) direct land-use for human settlements including housing, (2) indirect land-use associated with personal consumption, for example, food and clothing. Results show that an average urban resident's indirect land-use (199 176 ft2/capita) is ∼23 times the direct land-use (8519 ft2/capita), for a total urban CBLF of 207 695 ft2/capita. Rural residents have a slightly higher (∼6%) indirect land-use and ∼10 times larger direct land-use compared to urban. Because in both cases, indirect land-use is much larger than direct, a strategic mix of individual actions including halving food waste (-4.7%), one-day weekly plant-based diet (-3.3%), reducing clothing consumption (-2.8%), and others, can together reduce CBLF by -12.8%. Meanwhile, housing and locational choices across the urban-rural continuum evaluated for the median-density Minneapolis-St. Paul Metropolitan Statistical Area (MSP MSA) yield CBLF reductions from -1.9% (from single- to multifamily housing) to -10.6% (from rural to the urban core). The analysis demonstrates that consumer behavior changes could rival housing/locational choices in order to reduce personal CBLF. Our method of combining input-output analysis with parcel data could be applied in different regions to provide customized information on CBLF mitigation strategies.

Public Perception towards Waste-to-Energy as a Waste Management Strategy: A Case from Shandong, China.

Municipal solid waste (MSW) is posing great challenge for most countries in the world, which can cause severe negative impacts to the environment and human health. Waste-to-energy has great potential in China because of its technological maturity and policy support at the national level. However, there are significant conflicts between the huge market demand and strong public opposition. It is imperative to examine the public perception of waste-to-energy, especially for developing countries where a large number of projects are under construction or have been approved. The public perception of waste-to-energy was carried out by a questionnaire survey in this research. A total of 650 questionnaires were distributed and 629 questionnaires were returned, with a response rate of 96.8%. The results show that the public showed general concern in regard to environmental issues. Respondents had an overall positive attitude towards waste-to-energy, but it varied according to the demographic details of residents, such as age, education, and income. Recognition level of the benefits was higher than the concern of associated risks. Multiple linear regression shows that awareness of environmental issues had no impact on public attitude towards waste-to-energy, while public awareness and perceived benefits had notable positive impacts. Perceived risks had a positive correlation with public attitude. In order to promote the development of MSW incinerators, the government should make more publicity efforts. Rural residents, people over 50 years old, and people with low education and low income are the major groups which should be focused on to enhance the public perception. The findings provide a theoretical and practical reference for enhancing the social acceptance of waste-to-energy development.

Efficiency of Health Care Risk Waste Management in Rural Healthcare Facilities of South Africa: An Assessment of Selected Facilities in Vhembe District, Limpopo Province.

Waste generated form healthcare facilities is a potential source of health risks to the public, if it is not properly handled from the point of generation to disposal. This study was conducted to assess the efficiency of healthcare risk waste (HCRW) management in Vhembe District of Limpopo Province, South Africa. Fifteen healthcare facilities were selected in Vhembe District for this study. Data were obtained through in-depth interviews, semi-structured questionnaires, observation and pictures. Qualitative data were thematically analyzed, while the quantitative data were analyzed using the Statistical Package for the Social Sciences, version 25. In all the healthcare facilities; mismanagement of HCRW was noted at different points along the management chain. Poor segregation, overfilling of waste bins, inappropriate transportation and storage of waste in substandard storage rooms were observed in the facilities. All the waste from the district are transported to a private-owned treatment facility outside the district, where they are mainly incinerated. Enforcement of healthcare risk waste guidelines, provision of standardized equipment for temporary storage, empowerment of each healthcare facility to treat at least some of the waste, and employment of non-burn techniques for treatment of waste are recommended for more efficient management of healthcare risk waste in Vhembe District.
