Principles and methods of creating artificial vegetation cover on disturbed industrial lands

Biological reclamation is used to restore technogenically disturbed landscapes. Plant characteristics are important when choosing a plant assortment for the restoration of degraded areas. The purpose of this work was to study the principles and methods of creating artificial vegetation cover on disturbed industrial lands. Before carrying out biological reclamation, the surface was finished and a layer of potentially fertile soil layers with a capacity of at least 1 m and a fertile soil layer with a capacity of at least 0,5 m was applied. Before starting work, the quality of the seed material and its value were determined. Soil improvers (sapropel, latex, microorganisms, cellulose mulch) and biologics (TOP organic, complex of rhizospheric bacteria, hydrogel) were used for planting herbaceous and woody shrubby plants. After carrying out the hydraulic sowing activities, field germination of the seed was monitored every 10 days. Aerial photography was performed with an RGB camera using unmanned aerial vehicles of the DJI Phantom 4 Pro+ model with an on-board Global Navigation Satellite System receiver installed. It was found that the use of a biological product based on a complex of rhizospheric bacteria activated the processes of seed germination in experimental plots. Such activation made it possible to obtain productive bushiness of perennial crops in the early stages, due to which the area of vegetation covering the experimental site increased. The addition of hydrogel and TOP organic with a weight of 2 kg also had a positive effect on seed germination and plant survival. A comparative analysis of all experimental parameters revealed that the most effective projective coating of the site was obtained with the combined use of hydrogel and the preparation TOR-organic. At the same time, a further increase in the mass fraction of hydrogel in the substrate does not significantly affect the result of the creation of artificial vegetation cover on disturbed industrial lands.

REMOVAL OF HEAVY METALS FROM INDUSTRIAL SEWAGE SLUDGE BY APPLICATION OF VERMICOMPOSTING.

India faces a significant challenge with the escalating production of industrial sewage sludge, which contains hazardous heavy metals and toxins, posing a serious environmental threat. Managing the disposal of such waste is increasingly difficult due to its resistance to degradation. This research explores the potential of vermicomposting as a sustainable solution for mitigating heavy metal contamination in sewage sludge. Vermicomposting harnesses earthworms to accelerate organic matter decomposition and immobilize heavy metals. The study investigates various vermicomposting parameters, such as worm species, moisture levels, pH, and NPK to optimize heavy metal removal. Furthermore, it assesses the quality of the resulting vermicompost, focusing on heavy metal concentrations and potential agricultural applications. The findings indicate that vermicomposting holds promise as an eco-friendly method for addressing heavy metal pollution in sewage sludge, offering opportunities for sustainable waste management and soil enhancement. Key Words: Industrial waste, Heavy Metals, Land applications, Vermicomposting Method, Chemical speciation, Characterization and speciations.

New industrial land use policy and firms’ green technology innovation in China—an empirical study based on double machine learning model

China is facing a serious land resource mismatch problem, which will profoundly affect the acceleration of economic growth and technological innovation. Reform of the industrial land allocation system can solve the mismatch of land resources, and that also has an important impact on the promotion of economic and technological development. This paper selects the data of Chinese A-share listed companies in Shanghai and Shenzhen from 2007 to 2020 as the research sample, constructs a double machine learning model, and empirically investigates the impact of a new industrial land use policy on firms’ green innovation behavior. The study shows that: (1) the new industrial land use policy significantly promotes firms’ substantive and strategic green technological innovation, and the effect on substantive green technological innovation is greater than that on strategic green technological innovation. (2) The enhancement of R&D investment sustainability and the “talent pool” effect are important mechanisms through which the new industrial land use policy influences firms’ substantive and strategic green technological innovation. Meanwhile, the new industrial land use policy is conducive to firms’ green co-innovation. (3) There is heterogeneity in the effect of the new industrial land use policy, which can significantly promote green technological innovation of firms in the eastern region, while it does not play a significant role in the green innovation behavior of firms in the central and western regions. The above research results enrich the research in the field of industrial land and innovation, help to understand more comprehensively the mechanism of new industrial land affecting firms’ green technological innovation, and provide policy insights for strengthening the application of industrial land allocation reform in firms’ green innovation.

Environmental Inequality in Peri-Urban Areas: A Case Study of Huangpu District, Guangzhou City

This research investigates environmental inequalities within Guangzhou’s Huangpu District against the backdrop of rapid urbanisation and industrial expansion in Asia. This study identifies environmental hotspots, particularly in socially vulnerable areas characterised by high industrial density, using a vulnerability framework and analysing census and pollution data. Utilising satellite imagery, urban planning documents, and field research, we delve into the internal environmental conflicts arising from industrial land use. Our findings reveal how diverse stakeholders, guided by their rationales and interests, collectively contribute to spatial inequalities within a market-driven context. Importantly, we emphasise that environmental inequality transcends mere conflicts of interest among stakeholders and is fundamentally shaped by the prevailing market-oriented spatial development model in peri-urban areas. This model results in urban segmentation, socio-economic stratification, and an uneven distribution of environmental risks and resources. Our study advocates for a paradigmatic shift in China’s peri-urban spatial development and the integration of environmental protection and social equity alongside economic growth. We recommend moving away from short-term speculative practices and promoting long-term, community-engaged urban renewal strategies that harmonise economic progress with improved living standards and environmental sustainability.

Can Industrial Structure Upgrading Restrain Industrial Land Expansion? Evidence from China

Can Industrial Structure Upgrading Restrain Industrial Land Expansion? Evidence from China

Promotion incentives, economic growth targets and industrial land supply: evidence from China

ABSTRACT This study examines the impact of officials’ promotion incentives on the industrial land supply and explores the mediating role of economic growth targets, which are greatly influenced by local leaders. Using the panel data of 257 prefecture-level cities across China from 2007 to 2019, we identify the influence of officials’ promotion incentives on industrial land supply using a two-way fixed-effects model and then examine the mediating role played by the setting of economic growth targets using a mediating-effects model. The estimated results indicate that the promotion incentives of local leaders and the supply of industrial land by local governments follow a significant inverted U-shaped relationship, and that the economic growth targets play a partial mediating role. Heterogeneity analysis shows that the impact of promotion incentives for local leaders on industrial land supply is significantly heterogeneous due to differences in the age of local leaders and the economic development across different regions. The findings are important for improving China’s assessment system of officials, formulating economic growth targets, and optimizing the allocation of urban industrial land.

Characteristics of Microorganisms and Antibiotic Resistance Genes of the Riparian Soil in the Lanzhou Section of the Yellow River

Riparian soil is a critical area of watersheds. The characteristics of biological contaminants in riparian soil affect the pollution control of the watershed water environment. Thus, the microbial community structure, antibiotic resistance genes (ARGs), and mobile genetic elements (MGEs) in the riparian soil of the Lanzhou section of the Yellow River were investigated by analyzing the characteristics of soil samples collected from farmland, mountains, and industrial land. The results showed that the Proteobacteria, Bacteroidetes, and Actinobacteria were the dominant phyla in the riparian soil of Lanzhou section of the Yellow River. The microbial structure in the riparian soil was significantly correlated with the land use type (P < 0.05). The α diversity index of bacterial communities in land types was in the order of farmland > mountain > industry. Sulfonamide-typed ARGs were the most dominant genes in the soil of the Lanzhou section of the Yellow River Basin, among which the sul1 gene had the highest abundance, 20-36 000 times that of other detected ARGs. Moreover, the total absolute abundance of ARGs in industrial soil was the highest. Principal coordinate analysis (PCoA) displayed that the ARGs characteristics had a significant correlation with land types (P < 0.05), and intl1 and tnpA-04 drove the diffuseness of sulfonamide and tetracycline ARGs, respectively. Redundancy analysis (RDA) demonstrated that the content of inorganic salt ions and total phosphorus in the soil of the riparian zone of the Yellow River Lanzhou section were the main environmental factors, modifying the distribution of the microbial structure. Halobacterota and Acidobacteriota were the main microflora that drove the structural change in ARGs.

Development of a contextualized index of multiple deprivation for age-friendly cities: Evidence from Hong Kong

Deprivation refers to the state of having unmet basic needs, defined by societal standards. We argue that the mono emphasis on material deprivation is insufficient, as the characteristics of physical and social environments play a crucial role in either accelerating deprivation or providing additional resources/support to compensate for lack of income or basic household demands. We extend the focal point of the multiple deprivation framework to Hong Kong, an ultra-dense metropolis experiencing rapid demographic aging. We construct a Hong Kong index of multiple deprivation with seven domains. Highly deprived neighborhoods are likely to be located in areas with ultra-high residential density, where living conditions are substandard (e.g., subdivided units). Urban areas that used to have a large proportion of resettlement and industrial lands are likely to become deprived owing to the uneven distribution of urban amenities and the fragmentation of residential areas by industrial land.

Land price regulation and firms' global value chain position: Evidence from China

Exorbitant land prices have been a significant constraint on firm growth; however, few studies have explored their effect on firms' global value chain (GVC) positions. By treating the 2007 minimum price policy for industrial land as a quasi-natural experiment, this study estimates the impact of land price regulations on firms' GVC positions. Using a difference-in-differences method with continuous treatment intensity, we find that industrial land price regulation has a remarkably negative effect on firms' GVC positions. This effect is primarily observed in small- and medium-sized enterprises and private enterprises. The mechanism analysis suggests that industrial land price regulation has significantly increased the cost of land purchases by firms, squeezing their investment in innovation and reducing the quality of intermediate inputs, thereby degrading their position in GVCs.

Accumulation of Cd and Pb in sediments and Asian swamp eels (Monopterus albus) from downstream area of Cisadane River, Indonesia.

This study examined the presence of two heavy metals (Cd and Pb) in the sediments and Asian swamp eels (Monopterus albus) in the downstream area of Cisadane River. The average concentrations of Cd and Pb in the sediments from all sampling locations were 0.594 ± 0.230mg/kg and 34.677 ± 24.406mg/kg, respectively. These concentrations were above the natural background concentration and the recommended value of interim sediment quality guidelines (ISQG), suggesting an enrichment process and potential ecological risk of studied metals to the ecosystem of Cisadane River. The increase in contamination within this region may be attributed to point sources such as landfill areas, as well as the industrial and agricultural land activities in surrounding area, and experienced an increasing level leading towards the estuary of Cisadane River. Meanwhile, the average concentrations of Cd and Pb in the eels from all sampling locations were 0.775 ± 0.528μg/g and 28.940 ± 12.921μg/g, respectively. This study also discovered that gill tissues contained higher levels of Cd and Pb than the digestive organ and flesh of Asian swamp eels. These concentrations were higher than Indonesian and international standards, suggesting a potential human health risk and therefore the needs of limitations in the consumption of the eels. Based on the human health risk assessment, the eels from the downstream of Cisadane River are still considered safe to be consumed as long as they comply with the specified maximum consumption limits.

Оформление прав на публичные земельные участки для целей разработки месторождений полезных ископаемых: практические аспекты

The author comes to the conclusion that current problems associated with the registration of rights to a land plot are largely provoked by conflict of laws rules or gaps in the legislation. We are talking, first of all, about determining the spatial boundaries of a land plot that a subsoil user can lease without bidding, as well as about transferring an agricultural land plot into industrial land. In the latter case, difficulties arise due to the wording of the Law “On Transfer” regarding references to town-planning documents, as well as the need to provide a reclamation project. The article highlights the changing approach of judicial practice to the interpretation of the term “exclusive right” and the negative consequences of the lack of support from Rosnedra when registering rights to a land plot.

Spatial Transformation Analysis in Menganti Subdistrict: A Study of Peri-Urban Area Typologies in the Face of Urban Expansion

The swift urbanization of Indonesian cities, notably Surabaya, has spurred population growth and a heightened demand for land, leading to the expansion of urban areas into peri-urban regions like Menganti District. This district, bordering Surabaya, experiences significant land-use change shaped by the city’s expansion, making it a compelling area for analysis due to its complex dynamics. This study aims to analyze Menganti’s peri-urban spatial transformation and its typology based on the land-use triangle continuum theory. Using indicators like land-use proportions, building density, and educational and healthcare facility distribution, the analysis delineates four zones: Urban fringe, Urban-Rural fringe, Rural-Urban fringe, and Rural-fringe zones. The analysis further involves comparing land-use maps from 2017 and 2022, revealing that Urban fringe and Rural fringe zones primarily witness residential land use growth, while Urban-Rural fringe and Rural-Urban fringe display a mix of residential, industrial, commercial, and warehouse land use growth. Analyzing factors influencing spatial transformation in Menganti’s peri-urban area through Delphi and AHP techniques underscores elements like trend of land-use change, road networks, trade facilities, distance from the district center and Surabaya city, and land prices as pivotal influences. Understanding these dynamics aids in comprehending the evolving landscape and guiding sustainable development strategies in peri-urban regions experiencing urban expansion.

Governing sustainability: land use change impact on the palm oil industry in Riau Province, Indonesia

The aim of this research is to determine the social, economic, and ecological impacts of Land Use Change (LUC) of forest areas into Palm Oil industrial areas. The research method used was exploratory qualitative and analyzed using Nvivo 12 Plus. he findings of this study show that there are several challenges in the industrial land use of oil palm in forest areas in Riau, Indonesia, such as land conflicts between communities, government, private sector, forest destruction, and natural disasters. Therefore, we suggest that in order to expedite the removal of oil palm plantations from forest areas and to expedite the issuance of plantation licenses for community, private, and government entities wishing to enter such areas, both the federal government and local governments must adopt policies and impose sanctions. This study serves as a knowledge base to address the social, economic and ecological issues resulting from Land Use Change (LUC) in the province from forest areas to industrial areas producing oil palm. The conclusion of this research is that Land Use Change (LUC) from forest area to palm oil industry area in Riau Province, Indonesia has positive and negative impacts on social, economic, and ecological aspects in Riau Province, Indonesia. The government of the Indonesian province of Riau benefits from this research on land use change (LUC) in the palm oil sector.

Assessment of land use changes in Hung Yen province from 2010 to 2020, forecast to 2030 and proposed solutions for sustainable land use of the province

Hung Yen is a province in the Red River Delta, located in the center of the Northern Delta and the Northern Economic Zone (Hanoi - Hung Yen - Hai Duong - Hai Phong - Quang Ninh). Due to that favorable geographical location, in recent years, infrastructure and industrial parks in the province have developed strongly. The results of the assessment of land use changes in the period 2010-2020 in Hung Yen province show that the period 2015-2020 had more significant changes than the period 2010-2015. For industrial land, the period 2015-2020 saw an increase of 137.70%, while the period 2010-2015 saw an increase of 84.25%. Residential land, office buildings, transportation, and other non-agricultural land increased by 8.3% in the period 2015-2020, while it increased by 6.81% in the period 2010-2015. On the other hand, the agricultural land fund also saw a faster decline in the period 2015-2020 than in the period 2010-2015. For example, the area of land for perennial crops decreased by 18.71% in the period 2015-2020, while it decreased by 7.75% in the period 2010-2015. The results of the forecast of land use status to 2030 show that the area of non-agricultural land has surpassed that of agricultural land. In particular, the area of land for annual crops has decreased significantly, with a decrease of 8.88%, much higher than the 4.60% in the period 2010-2020. This type of land was used for growing rice and other vegetables to ensure food security for the province and the country. In addition, due to the shrinking agricultural land area, it is necessary to switch the crop structure to be suitable for climatic conditions as well as for each type of soil and terrain conditions. In addition, it is necessary to apply scientific and technical methods to agriculture to increase productivity and achieve high economic efficiency.

Soil organic carbon as an indicator of land use impacts in life cycle assessment

PurposeAnthropogenic activities are a major driver of soil and land degradation. Due to the spatial heterogeneity of soil properties and the global nature of most value chains, the modelling of the impacts of land use on soil quality for application in life cycle assessment (LCA) requires a regionalised assessment with global coverage. This paper proposes an approach to quantify the impacts of land use on soil quality, using changes in soil organic carbon (SOC) stocks as a proxy, following the latest recommendation of the Life Cycle Initiative.MethodsAn operational set of SOC-based characterisation factors for land occupation and land transformation were derived using spatial datasets (1 km resolution) and aggregated at the national and global levels. The developed characterisation factors were tested by means of a case study analysis, investigating the impact on soil quality caused by land use activities necessary to provide three alternative energy supply systems for passenger car transport (biomethane, ethanol, and solar electricity). Results obtained by applying characterisation factors at local, regional, and national levels were compared, to investigate the role of the level of regionalisation on the resulting impacts.Results and discussionGlobal maps of characterisation factors are presented for the 56 land use types commonly used in LCA databases, together with national and global values. Urban and industrial land uses present the highest impacts on SOC stocks, followed by severely degraded pastures and intensively managed arable lands. Instead, values obtained for extensive pastures, flooded crops, and urban green areas often report an increase in SOC stocks. Results show that the ranking of impacts of the three energy systems considered in the case study analysis is not affected by the level of regionalisation of the analysis. In the case of biomethane energy supply, impacts assessed using national characterisation factors are more than double those obtained with local characterisation factors, with less significant differences in the other two cases.ConclusionsThe integration of soil quality aspects in life cycle impact assessment methods is a crucial challenge due to the key role of soil conservation in ensuring food security and environmental protection. This approach allows the quantification of land use impacts on SOC stocks, taken as a proxy of soil quality. Further research needs to improve the assessment of land use impacts in LCA are identified, such as the ability to reflect the effects of agricultural and forestry management practices.

Analysis of The Implementation of Sustainable Food Agricultural Land Protection Policy in Bandung District: A Case Study of Rice Field Conversion in Cikancung District

The policy of sustainable protection of agricultural land becomes crucial in addressing land degradation and land use conversion, especially from agriculture to non-agriculture, alongside the increasing demand for land due to population growth and economic development, which can lead to negative impacts such as a decrease in food security, marginalization of agricultural land, and an increase in flood risks. This research aims to analyze the implementation of the Sustainable Protection of Food Agricultural Land Policy, understand the rate of paddy field conversion, and identify trends in land conversion after the policy's enforcement. This study employs a qualitative approach, with data obtained through interviews, observations, and documentary studies. The research is conducted in Bandung Regency, with samples taken from Cikancung Sub-district, Bandung Regency, West Java Province. Informants involved in this research are selected through judgment sampling and are individuals related to the sustainable protection of agricultural land policy and relevant stakeholders. Data analysis is conducted using qualitative and spatial analysis. The research findings indicate that the implementation of sustainable agricultural land protection policy in Bandung Regency is still in the socialization and planning stages. Based on spatial analysis, the implementation of the policy in Cikancung Sub-district has led to the conversion of paddy fields, particularly in non-technical irrigation paddy fields, predominantly converted into industrial land. This conversion covers a total area of 20.3 hectares, with the most significant change occurring in non-technical irrigation paddy fields converted into industries, covering an area of 13.7 hectares. Based on internal, external, and policy analysis, it can be concluded that the policy implementation in Cikancung Sub-district has not been optimal in addressing the conversion of paddy fields.

Urban industrial land misallocation and green total factor productivity: Evidence from China's Yellow River Basin regions

AbstractThis study aims to investigate the repercussions of urban industrial land misallocation on green total factor productivity (GTFP) within the context of China's Yellow River Basin regions. Utilising data from 99 prefecture‐level cities over the period from 2007 to 2020, the analysis reveals that the misallocation of urban industrial land exhibits regional variations and exerts a significant and persistent negative influence on GTFP, with notable regional disparities. Further analysis shows the mechanism of this effect is the obstacle to urban innovation due to industrial land misallocation. In addition, education expenditure plays a moderating role both directly and indirectly. These findings imply the need to continuously improve the performance evaluation and financial system of local governments, reduce government intervention, and make use of the market mechanism in the allocation of urban industrial land.

The identification and efficiency evaluation of industrial parcels by integrating multi-source spatial data in Shenzhen, South China

ABSTRACT Industrial land status, encompassing quantity, distribution and efficiency, is pivotal in urban planning and sustainable development. However, obtaining detailed and up-to-date industrial land maps poses a significant challenge in many developing countries due to rapid urban expansion. Furthermore, the identification and efficiency assessment of industrial land at the parcel scale are rarely undertaken. To address these challenges, our study proposes an innovative approach to map industrial land, categorize its types and assess its efficiency at the parcel scale. We select Shenzhen, one of China’s largest industrial cities, as a case study to demonstrate the effectiveness of our method. Our results unveil several key findings: (1) Shenzhen’s urban area was meticulously segmented into 15,591 multi-size socio-economic parcels, of which 5,738 were identified as industrial parcels (IPs); (2) IPs were further categorized into three distinct types: office industrial parcels at 69.47%, manufacturing industrial parcels at (6.08%) and comprehensive industrial parcels at 24.45%; (3) Their efficiency was classified into four levels: low (20.30%), middle (35.73%), fine (35.97%) and high (8.00%). Efficient IPs were predominately concentrated in the southwest, whereas other IPs clustered in the northwest. Our findings can provide valuable insights into industrial land identification, classification and efficiency evaluation at parcel scale.
