“…Compared to the management of water and air pollution, many urban areas are facing increasingly severe issues regarding solid waste-management (Lee et al 2021 ). The Chinese government and Anhui province have prioritized solid waste management, issuing a series of central and local policies (Gu et al 2021a ). The Chinese government proposed a work plan for a pilot construction of the “Zero-waste City.” Tongling city in Anhui province and other 16 pilot cities and regions were selected for pilot projects in 2019 (Meng et al 2021 ).…”

“…However, using SIE cannot reveal the multidimensional and comprehensive characteristics of IGG. The second group is to establish a multidimensional indicator evaluation (MIE) by employing EWA (Gu et al 2021a ; Wu and Zhou 2021 ; Zhang et al 2022 ), entropy-TOPSIS method (Chen et al 2020a ), and factor analysis method (Li et al 2021 ). Additionally, using a single method is difficult to successfully provide the all-sided characteristics of IGG.…”

Inclusive green growth (IGG) offers an effective alternative to pursue sustainable development. The core of the IGG system lies in the coordination of inclusive, green, and growth subsystems. However, there is little quantitative assessment on IGG based on subsystem collaboration. This study proposes a holistic scheme of inclusive-green-growth nexus in Anhui province from 2009 to 2018 by using an integrated approach, namely, the entropy weight approach (EWA), coupling coordination degree model (CCDM), grey prediction model (GPM), and obstacle factor diagnostic model (OFDM). The results show that: (1) The proposed integrated approach could be viable to measure the synergistic interactions among internal IGG subsystems; (2) At the provincial level, a relatively high IGG performance but a low coupling coordination degree (CCD) of the IGG nexus are seen. Although the predicted value of CCD will show an upward trend, it will not be able to cross the start stage. The obstacle factors on the coordinated development of IGG can be divided into two stages: (3) At the prefectural level, the cities in which CCD is rising outnumber those it is falling. However, the CCD is also low, and the gap between cities is getting wider. The obstacles that affect the CCD of cities see a dynamic evolution trend from “inclusive obstacle type” to “inclusive and growth obstacle type” then to “green obstacle type” over the decade.

“…The minimizing-land ll scenario indicates that reducing the amount and share of land lling, as the measures taken by the Chinese government currently, will lead to a considerable contribution to decreasing GHG emissions from land lls. In recent years, implementation of relevant laws, regulations, and programs (such as the Anti-Food-Waste Law, the Opinions on Further Strengthening the Control of Plastic Pollution, Zero-waste Pilot Cities, and Compulsory Waste Source Separation Program) will reduce the amount of food waste and plastic waste in land lls in the future 21,45 . Many cities in China regarded separation rate of household food waste as an important indicator to measure the performance of MSW source separation program; for example, the MSW separation rate of Beijing increased from 1.4-20% from 2020 to 2021 46 .…”

Landfills, one of the final destinations of all kinds of materials used by human beings, are vital for understanding the carbon cycle of cities. Global Methane Pledge at COP26 highlighted the significance of landfill, which was the third-largest source of methane emissions in the world. High temporal- and spatial-resolution datasets of landfill organic carbon stocks and flows are crucial for formulating national carbon reduction strategies; however, current research is very limited. Here, a quantitative-based solid-water-gas coupling transformation model of organic carbon cycles in landfills was established, and the landfills of 346 cities in China were chosen as the studied case to show its temporal shift and spatial distribution of organic carbon stock and greenhouse gas (GHG) emissions from 2001 to 2030. In the past twenty years, the organic carbon stock in municipal solid waste landfills in China was 503.3 ± 4.2Tg, with 6.4% and 0.3% of the organic carbon input transferred into the atmosphere and aquatic environment, respectively. The organic carbon stock in landfills has the dual attributes of resource value and environmental impacts, showing significant differences among regions. In the Northeast China and Northwest China, the soil-like resource and renewable energy potential from landfills were higher, while in South China, the methane emission from landfills was greater than that in other regions. Our scenarios analysis finds that raising the methane collection rate, minimizing landfilling rate, and implementing landfill mining and eco-remediation measures can reduce the GHG emissions by 4.6%, 13.4%, and 53.0%, respectively, compared to that in the business-as-usual scenario, by 2030. The GHG reduction by 2030 is 836.2Tg, accounting for 1.1%-3.6% and 1.2%-8.7% of the GHG emission gaps for China to achieve 1.5℃ and 2℃ warming targets under landfill-remediation scenario. Landfills can be potentially a carbon-negative sector if all of the policy-interventions are applied, and thus contribute to the carbon-neutral strategy of China by 2030.

Housing and urban design for COVID-19 pandemic; design for prevention of virus spread

The new COVID-19 disease, which is affecting the world and has infected and killed many people, has rapidly changed people’s lifestyles and, accordingly, changed people’s needs, including their demands on their living environment. As the disease progressed, people were forced to stay at home to escape the disease. Even cities and public spaces could no longer be used. These situations, as well as the anxiety caused by this unknown disease, quickly led to mental health problems such as depression, isolation, aggression, stress, and physical illnesses due to inactivity. Given that the living environment of people, and above all, their homes, has a direct impact on the physical and mental health of people, profound and fundamental changes and decisions in the design and construction of houses are necessary for this situation where people have to spend most of their time in their homes. On the other hand, people need to socialize with each other and do their daily and essential tasks easily, even in a pandemic situation. Therefore, the urban design must also have significant changes in accordance with these conditions. In this article, we will review the design strategies of the city and the design and construction of houses to better respond to them in such situations.
