Driving Factors and Scale Effects of Residents' Willingness to Pay for Environmental Protection under the Impact of COVID-19

In recent years, environmental degradation and the COVID-19 pandemic have seriously affected economic development and social stability. Addressing the impact of major public health events on residents' willingness to pay for environmental protection (WTPEP) and analyzing the drivers are necessary for improving human well-being and environmental sustainability. We designed a questionnaire to analyze the change in residents' WTPEP before and during COVID-19 and an established ordinary least squares (OLS), spatial lag model (SLM), spatial error model (SEM), geographically weighted regression (GWR), and multiscale GWR to explore driver factors and scale effects of WTPEP based on the theory of environment Kuznets curve (EKC). The results show that (1) WTPEP is 0–20,000 yuan before COVID-19 and 0–50,000 yuan during COVID-19. Residents' WTPEP improved during COVID-19, which indicates that residents' demand for an ecological environment is increasing;(2) The shapes and inflection points of the relationships between income and WTPEP are spatially heterogeneous before and during COVID-19, but the northern WTPEP is larger than southern, which indicates that there is a spatial imbalance in WTPEP;(3) Environmental degradation, health, environmental quality, and education are WTPEP's significant macro-drivers, whereas income, age, and gender are significant micro-drivers. Those factors can help policymakers better understand which factors are more suitable for macro or micro environmental policy-making and what targeted measures could be taken to solve the contradiction between the growing ecological environment demand of residents and the spatial imbalance of WTPEP in the future.

Chemical characteristics and sources of PM2.5 in Hohhot, a semi-arid city in northern China: insight from the COVID-19 lockdown

A knowledge gap exists concerning how chemical composition and sources respond to implemented policy control measures for aerosols, particularly in a semi-arid region. To address this, a single year's offline measurement was conducted in Hohhot, a semi-arid city in northern China, to reveal the driving factors of severe air pollution in a semi-arid region and assess the impact of the COVID-19 lockdown measures on chemical characteristics and sources of PM2.5. Organic matter, mineral dust, sulfate and nitrate accounted for 31.5 %, 14.2 %, 13.4 % and 12.3 % of the total PM2.5 mass, respectively. Coal combustion, vehicular emission, crustal source and secondary inorganic aerosols were the main sources of PM2.5 in Hohhot, at 38.3 %, 35.0 %, 13.5 %, and 11.4 %, respectively. Due to the coupling effect of emission reduction and improved atmospheric conditions, the concentration of secondary inorganic components, organic matter and elemental carbon declined substantially from the pre-lockdown (pre-LD) period to the lockdown (LD) and post-lockdown (post-LD) periods. The source contribution of secondary inorganic aerosols increased (from 21.1 % to 37.8 %), whereas the contribution of vehicular emission reduced (from 35.5 % to 4.4 %) due to lockdown measures. The rapid generation of secondary inorganic components caused by unfavorable meteorological conditions during lockdown led to serious pollution. This study elucidates the complex relationship between air quality and environmental policy.

A public geography note. Not exactly encouraging signs on ecological transition in Italy

There is quite a lot of narrative around ecological transition (ET) these days, especially with reference to the post-covid 19 economic recovery. In Italy, within the Draghi's gov, a special Ministry has been established to that purpose. We shall clarify, however, that the ET approach is not only a sequence of actions to fix what was damaged on the territory, or a number of punctual works here and there. It's rather a wide prospect with multiple sub-sets that will evolve in the long term through a coherent set of transcalar measures. Two events oppose this ET idea, both happening in Italy during the course of May 2021: i) the return of the “nuclear discourse”;ii) the reduction of the Sirente-Velino Regional Park size. We will discuss about this shortly, looking at it from a public geography perspective. In addition, we will summarize some of those critical elements of the ET ongoing implemented practices. © 2021 Ekonomia i Srodowisko. All rights reserved.

Environmental policies for the treatment of waste generated by COVID-19: Text mining review.

The rapid transmission of COVID-19 has meant that all economic and human efforts have been focused on confronting it, ignoring environmental aspects whose consequences are causing adverse situations all over the planet. The saturation of the sanitary system and confinement measures have multiplied the waste generated, which implies the need to adapt environmental policies to this new situation caused by the pandemic. It is a review article whose objective was to identify the environmental policies that would facilitate an adequate treatment of the waste generated by the pandemic. It was proposed to analyse the current lines of research developed on this paradigm, applying the text mining methodology. A systematic review of 111 studies published in environmental journals indexed in the Web of Science was carried out. The results identified three areas of interest: knowledge of transmission routes, management of the massive generation of plastics and appropriate treatment of solid waste in extreme situations. Leaders are called upon to implement the contingency plans to sustainably alleviate the enormous waste burden caused by society's adaptation to the restrictions imposed by the pandemic. Specifically, innovation aimed at achieving the reuse of medical products, the promotion of the circular economy and educational campaigns to promote clean environments should be encouraged.

The challenges of Covid-19 pandemic on improving plastic waste recycling rates.

The plastic system is burdened with many inefficiencies that have been exposed, and exacerbated, by the outbreak of the coronavirus (SARS-CoV2) pandemic in December 2019, widely known as COVID-19, and which threaten society's commitment to transition to a sustainable plastics economy. This perspective aims to depict the structural and systemic inefficiencies of the plastics system, and illuminate: (a) the vulnerability of the recycling sector to macroeconomic - particularly to oil price - shocks; (b) the economics of the recycling system; (c) the political dimensions of the plastics sector. It emphasises that is unwise to think about plastics recycling as an insular and linear problem, due to the complexity and interconnectedness of different parts of the plastic system that affect and are affected by the intertwined processes, stakeholders and values. That said, the transition to a sustainable plastics system requires an integrated, knowledge-based systems approach that interrogates the dynamics and causal-effect relationships of the interconnected challenges. This analytical scrutiny can indicate where interventions are needed in the plastics system towards creating transformational change.

Circular Economy and Sustainability as a Basis for Economic Recovery Post-COVID-19.

The global COVID-19 crisis has led to a reduction in productive and commercial activity, as well as in the use of transport, which has led to a notable decrease in pollution levels. The paralysis of economic activity requires the commitment of government policies to impose economic recovery laws based on sustainability. The aim of this paper is to briefly review the situation that COVID-19 has caused in the environment and sustainability. In addition, a critical view of it is provided, and possible solutions for a sustainable economic reconstruction are offered. The coronavirus is revealing the fragility of the current economic system, based on profit and continuous consumption of resources. This model generates many problems such as pollution, contribution to climate change, loss of biodiversity or unfair distribution of wealth. This must be an opportunity to redefine the social purpose of business and help generate a sustainable world through economic policies. For economic recovery, a plan oriented towards energy and ecological transition and based on the circular economy must be followed.

Transformation of a Ferry Ship into a Ship Hospital for COVID-19 Patients.

Liguria is a northwestern region of Italy that, since the WHO has declared COVID-19 as a pandemic (11 March 2020), presented 108 patients hospitalized, 34 of which were in the intensive care unit. Due to this serious epidemiological emergency, the transformation of a long-distance ferry ship into a hospital ship for COVID-19 patients who were still positive after the acute phase of the illness was carried out to free up hospital beds for patients in the acute phase. The ship was moored in the port of Genoa, the capital of Liguria. The conversion was localized to a single deck, where designated healthcare areas were identified. From 23 March to 18 June 2020, 191 patients were admitted onto the ship; they were provided with high-level healthcare guaranteed by the multi-disciplinary nature of clinical competencies available. Patients had a favorable outcome in all cases, confirmed by their recovery and negative swab results. Moreover, no cases of voluntary discharge were recorded. To the best of our knowledge, this is the only example in the world in which a passenger ship was transformed into a ship hospital for COVID patients.
