Food, Energy, and Water Nexus at Household Level: Do Sustainable Household Consumption Practices Promote Cleaner Environment?

COVID-19 incidence of poverty: How has disease affected the cost of purchasing food in Pakistan

COVID-19 harms health and income generation activities. The pandemic caused poverty, and food crisis in the most vulnerable and underprivileged segments. Economic turbulence and massive poverty during epidemic period probably resulted in short-term food insecurity and low food consumption. Based on these concerns, the current study examined how COVID-19 has impacted Pakistan's cost of purchasing food. The study surveyed total 1067 Punjab and Sindh residents in Pakistan, from July to October 2021. A structural equation model was used to examine the interrelationship among food intake, food purchasing cost, and health effects. We investigated whether people experienced substantial effects from the loss of a source of income, work hours, debt burden, and food inflation on their food intake. These circumstances all negatively affected food intake, reducing food consumption. Besides COVID-19's effects on direct income, 41% more people fall into poverty and 23% can't afford healthy food. People's socioeconomic circumstances affects poverty levels and affordable healthy food costs. The cost of purchasing food is significantly correlated with health outcomes. A significant and positive correlation between COVID-19 and income effects, and a negative correlation between food consumption and adverse income effects was explored. In addition, people increased their demand for food assistance during COVID-19 to mitigate negative income shocks. People who cannot afford minimal food costs should be offered food through mobile vehicles or delivery channels in the short term. Cash transfers or subsidies could also be provided to the needy during crisis time.

The effect of the elderly and child care on household carbon emissions

The aim of this work is to investigate the different implications in terms of the elderly and child care on household carbon emissions in China. We estimate the effect of family structure on household carbon emissions in the 2018 China Family Panel Studies (CFPS), by means of the STIRPAT model. The results indicate that significant differences exist between the effect of the elderly and child care on each household's carbon emissions. Moreover, there is a negative effect between the elderly and household carbon emissions with an elasticity coefficient of -0.029, and a positive effect between children and household carbon emissions with an elasticity coefficient of 0.008. Interestingly, the elderly and children have an interactive effect on carbon emissions except for housing carbon emissions. To be specific, the elderly and child care have a mutual inhibition effect on the health carbon emissions of household, whereas they have a mutually reinforcing effect on other carbon emissions. Low carbon emissions paths in household should be urgently explored, and deliberate policy action is required to achieve carbon emissions reduction.

Food Waste Utilization for Reducing Carbon Footprints towards Sustainable and Cleaner Environment: A Review

There is world-wide generation of food waste daily in significant amounts, leading to depletion of natural resources and deteriorating air quality. One-third of global food produced is wasted laterally with the food value chain. Carbon footprint is an efficient way of communicating the issues related to climate change and the necessity of changing behavior. Valorization or utilization of food wastes helps in resolving issues related to environment pollution. Reduction in the carbon footprint throughout the chain of food supply makes the whole process eco-friendly. Prevailing food waste disposal systems focus on their economic and environmental viability and are putting efforts into using food waste as a resource input to agriculture. Effective and advanced waste management systems are adopted to deal with massive waste production so as to fill the gap between the production and management of waste disposal. Food waste biorefineries are a sustainable, eco-friendly, and cost-effective approach for the production of platform chemicals, biofuels, and other bio-based materials. These materials not only provide sustainable resources for producing various chemicals and materials but have the potential to reduce this huge environmental burden significantly. In this regard, technological advancement has occurred in past few years that has proven suitable for tackling this problem.
