This article examines the changing role of the local government’s environmental management in Guangzhou, China, through a historical content analysis of archival data. Environmental governance in Guangzhou has followed a government-led, top-down model. The content analysis showed that over the past four decades, the role of Guangzhou’s municipal environmental governance has been characterized by transformation – from passive responses to accelerating and securing economic growth, and finally to active interventions that balance economic growth and ecological protection. The changing role of the Guangzhou government in environmental governance is driven by varied urban political priorities at different historical stages. This article argues that the urban political economy and the national government’s commitment to pragmatic, sustainable development shaped the local government’s response to environmental problems.

The release of CO 2 from the construction industry poses an alarming condition to the society/environment and necessitates the development of a sustainable replacement to the ordinary portland cement (OPC). Geopolymer Concrete (GPC) is a futuristic sustainable alternative to use as a binder. The characteristics of GPC is evidently proved to be better than OPC based on the literature. From the existing studies, the base materials for the production of GPC generally differs. Therefore, the hydration of the final output (GPC) differs. Thus the behaviour of GPC under corrosion is required to be studied specifically. This aspect has narrowed the available literature on the behaviour of GPC under corrosion. In this study the behaviour of the fly ash based GPC and OPC specimens under accelerated corrosion were compared. GPC specimens under accelerated corrosion showed an average corrosion rate of 13 to 15 g/year demonstrating a moderate corrosion rate. Concurrently, the rate of corrosion in OPC specimens is around 25 g/year exhibiting a high corrosion rate. It is evidently proven that, comparatively GPC has better resistance to corrosion than OPC.

Ports play an important role in transportation networks, but the ecological efficiency of many ports cannot reach an effective level. To improve the ecological efficiency of ports, we need to analyze the current ecological efficiency of ports and propose policy recommendations based on the results. In this paper, we first employed the super-efficiency SBM model to calculate the ecological efficiency of the four major ports in the Yangtze River Delta port group from 2011 to 2021. The results showed that the average comprehensive ecological efficiency of the four major ports was 0.647, which did not reach the effective level. The overall ecological efficiency curve was U-shaped. Then we used the Tobit model to analyze the key factors affecting the port’s ecological efficiency. We found that the economic development of port cities could promote the improvement of port ecological efficiency. The application level of emerging technologies also had a positive impact, but the impact was weak. However, expanding the scale of the port would reduce its ecological efficiency. At last, we provided some policy recommendations.

Based on remote sensing image interpretation data of land use/cover change (LUCC) for six periods from 1995 to 2020, we used the equivalent factor method to assess the value of ecosystem services (ESV) in Jiangsu Province and investigated its spatial and temporal evolution characteristics on the grid scale in combination with spatial autocorrelation analysis. The results showed that total value of ecosystem services in Jiangsu Province is on the rise, with an increase of 3.15 billion USD compared with that in 1995. Water area has the largest proportion of ESV and hydrological regulation makes the greatest contribution among ecosystem services, reaching 32.99 billion USD in 2020. The value of ecosystem services measured by the coefficient of sensitivity index of various land use types is as follows: water area>cropland>forestland>grassland>unused Land. Ecosystem service value is positively correlated to spatial distribution, but the correlation is gradually weakening, and the clustering relationship is dominated by high–high and low–low aggregation. The study’s findings will serve as useful guidelines for creating policies in Jiangsu Province pertaining to land use planning and eco-environmental protection.

Air pollution control is an important link in the construction of ecological civilization, and government vertical regulatory reform is a key factor affecting air pollution control. This article takes China’s city-county merger as a typical policy for government vertical regulatory reform, and uses the staggered DID to estimate the impact of government vertical regulatory reform on air pollution. we find that China’s city-county merger could reduce air pollution, but this effect is mainly effective in the border areas of administrative regions and western regions. Further analysis shows that the reduced air pollution originating from the reformed areas can be attributed to reduced financial expenditure pressure and reduce the productive expenditure. The results in this study provide a reference for the government to adjust the power allocation at the city and county levels.

In the complex mountainous environment, it is valuable to explore the variation rule of soil pH for accurately managing soil pH and the sustainable use of soil. In this study, we collected 394,736 field surface soil samples and recorded the paired environmental conditions in Guizhou Province. The spatial autocorrelation, semi-variance model and geographical detector were employed to analyze the spatial structure characteristics and distribution pattern of soil pH. The results showed that the surface soil pH varies from 3.11 to 8.99, with the variation coefficient of 17.14%. Soil pH shows a patchy mosaic distribution pattern. The structural factors of climate, parent material, and topography play a determinant role in controlling pH differentiation. Geo detector analysis showed that the explanatory power of environmental factors for the soil pH differentiation is in the order of parent rock (0.0976) > altitude (0.0144) > soil temperature regime (0.0112) > land use (0.00503) > soil moisture regime (0.000812). The reciprocal effect of parent rock and altitude is noticeable.

The study aimed to investigate the prevalence and biodiversity of yeasts in the soil and water samples of the city and district of Alytus after a fire at a tire processing plant. 11 soil and 3 water samples were taken each year for the periods of 2019-2021. The yeast count in the soil samples ranged from 10 2 to 10 5 CFU/g. In water samples, the count of yeasts varied between 0.00-10 3 CFU/g. A total of 114 yeast isolates were isolated from the soil samples and 46 yeast species were identified. No statistically significant changes in the phyla distribution of yeast species isolated from the soil were observed during the different study periods. A total of 25 yeast isolates were isolated from the water samples and 14 yeast species were identified. Statistically significant differences in the phyla distribution of yeast species isolated from water samples were observed. The obtained research data showed that the results of all chemical soil tests do not exceed the limit values specified in Lithuanian legal acts. The obtained results of the study allow us to state that the fire at the tyre recycling plant did not affect the prevalence and biodiversity of soil yeasts, but the possibility that the effect will be noticed after a longer period of time cannot be ruled out. We believe that this study significantly contributes to the dissemination of information about the fire at the tire recycling plant and its impact on the environment, brings more clarity and reduces doubts about the possible impact of pollution on the environment.

Rawapening Lake is located in Semarang Regency, Central Java Province, Indonesia, and is the center of various activities, including agriculture, fisheries, sources of electrical energy, raw water, tourism, and culture. A 100-cm-long sediment sample was extracted from Rawapening Lake to reconstruct the dynamics of environmental change by observing the preserved diatoms. Diatoms are sensitive to changes in water quality, so their pattern of existence can reflect changes in lake conditions. The sampling location is located at the mouth of the Tuntang River, the only outlet of Rawapening Lake, which has 20 inlets as water sources. Sediment cores were sliced at 1-cm intervals for diatom analysis. Diatom slide mounts were prepared from about 5 grams of dry sediment using 10% hydrochloric acid

Noise generated by air traffic is one of the leading problems in urban areas in the world. That is why the measures for reducing the noise generated by air traffic are today the subject of constant improvement, extensive research, and standardization. Monitoring and predicting air traffic noise levels represent an important factor in quality control and noise management. In order to reduce the noise level in the vicinity of Mitiga International Airport (Tripoli) in Libya, the aim of this paper is to assess the noise emission levels before and after the introduction of certain measures to reduce airborne noise, as well as to predict the noise level at the analyzed area. The method of interpolation in the Geographic Information System (GIS) was used to graphically represent the spatial distribution of noise emissions in the study area, and by applying zonal statistics deviations from the allowable values for each control grid were calculated. The obtained results showed that the application of certain measures has a great impact on reducing noise levels on controlled grids. Finally, the reliability of noise level prediction was successfully assessed using the artificial neural network (ANN) method.
