The purpose of the article is to improve the state management of the system of rational environmental use in the context of commercial development of the bioeconomy. The focus of the study is the system of state management of rational environmental use. The scientific task is to model the process of making and implementing managerial decisions on the implementation of state management of the system of rational environmental use in the context of commercial development of the bioeconomy. Modelling was used within the context of commercial development of the bioeconomy for EU member. To achieve this task, two key methodologies were used: The modeling method BPMN (Business Process Model and Notation) and the method of hierarchy analysis (MHA). Thus, using the BPMN method and the MHA, we have modelled the stages of environmental management in the context of commercial development of the bioeconomy for EU member states by using key criteria. Based on these results, a number of management solutions were proposed. The innovativeness of the study lies in the fact that a qualitatively new modeling method was used to improve the implementation of the state management of the system of rational environmental use in the context of commercial development of the bioeconomy. In addition, a model specific to EU countries has been developed but with limited scope of use. In future studies, it is planned to expand the list of criteria that will be used to further develop the model, as well as unify it for a larger number of countries.

This study discusses government policy, focusing on political-ecological commitment to licensing and tax collection for non-metallic mineral and rock mining, which is spread across almost 30 regional government areas in North Sumatra, Indonesia. Based on existing data, there are 700 mines that are not licensed, operate freely and without supervision by the government, causing serious environmental damage and state financial losses from the mining tax sector. The research method uses qualitative with purposive (exclusive) sampling and field studies. The research results showed that the commitment to managing permits and taxation of non-metal minerals and rocks continues to be problematic, and includes the non-implementation of supervision of mining permits and tax collection and the lack of special policies and handling procedures by regional and central governments. Handling internal mining governance policies and the monitoring process requires assistance from law enforcement officials such as the Regional Police and Corruption Eradication Commission to prevent fraud in granting mining business permits. Through this assistance mechanism, examples of sustainable mining monitoring and supervision will be produced that are useful for the government so that mining business actors can continue to be supervised with official permits.

Climate change and environmental deterioration pose significant threats to the long-term well-being of our planet. The study focuses on measuring the impact of Carbon Pricing Mechanism on financial flows toward sustainable projects. To meet the research objectives, the first questionnaire was developed by conducting the factor analysis of the variables framed after a review of the literature, and then PLS-SEM was applied to a sample size of 363. On running the analysis of SMART-PLS 4, it was found that there is a strong relation between dependent and independent variables but a weak relation of moderation. The analysis covered in this research has important consequences for efficient corporate management. It offers a strategic plan for making well-informed decisions, which is the foundation of effective management. From a managerial perspective, the findings underscore the critical significance of policy interventions, specifically carbon pricing mechanisms, in shaping the flow of financial resources towards sustainability initiatives. Businesses should recognize that these policies possess the capacity to significantly impact public comprehension and perception of climate change.

One form of mangrove ecosystem service is carbon sequestration. The issue of carbon is an important concern for the climate change response. The purpose of this study is to determine the comparison of stand carbon stock estimates in mangrove ecosystems on the coast of East Lampung Regency (Kuala Penet Resort Mangrove Forest, Lampung Mangrove Center (LMC) Mangrove Forest, and Register 15 Mangrove Forest). The stages of research include: determination of data collection based on purposive sampling and Forest Health Monitoring (FHM) techniques; stand biomass and carbon calculations using allometric equations and the Intergovernmental Panel on Climate Change (IPCC); descriptive data analysis; and a literature study. Based on the results of the study, the highest stand carbon was in LMC (144.56 tons per ha), and the lowest was in Kuala Penet Resort (19.19 tons/ha). These conditions are influenced by stand structure factors (growing conditions, tree age, and microclimate conditions) and management schemes. The partnership is a form of stakeholder commitment as a way to maintain mangrove ecosystem services. Thus, carbon stands in coastal mangrove ecosystems of East Lampung Regency, namely Kuala Penet Resort (19.19 tons/ha), Register 15 (9.66 tons/ha), and LMC (144.56 tons/ha).

At present, green marketing attract the attention of academics and professionals around the world. Research on green marketing/sustainable marketing has increased in recent years. Through a systematics review, this study aims to analyze the development and trends of research with the theme customer loyalty within the scope of green marketing/sustainable marketing last 10 years (2013-2023). This study uses Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Analysis is carried out based on productive countries, authors, institutions, journals, and distribution phrases. This study also analyzed articles based on the methods and variables used, along with outcomes. 33 selected documents were analysed using Wordstat. The results showed that United States is the most productive country that publishes articles on related topics. Green marketing, customer loyalty, customer satisfaction, green products, green image are phrases that often appear with a frequency limit of 200. Structural Equation Modelling (SEM) is a method that is often used.

This review evaluates polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) analytical methods, occurrence and concentrations in major food groups from studies published worldwide over the last 20 years. The review reveals that in many developing countries the levels of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) plus dl-PCBs may be increasing due to rudimentary practices during thermal process including waste incinerations, metal industries, recycling and dumpsites. The review heightened the need to develop and capacitate laboratories from developing world for PCDD/Fs plus dl-PCBs monitoring as most of the analysis were performed in laboratories from developed worlds even on sentinels from developing countries, especially those of Africa. The review concluded that further data still need to be generated from other regions to complete the chemical inventories. It was concluded that, strict environmental controls of PCDD/Fs plus dl-PCBs emissions remain a priority, however reduction of these contaminants require global monitoring coordination.

The urban fringe area is a transitional area between urban and rural areas which supports urban ecological functioning. Vegetation is an element of biodiversity that is important for the sustainability of urban life. The balance of the ecosystem is maintained with the help of the biodiversity of the urban fringe area where environmental functions and services will be able to run optimally. The important value index (IVI) in the vegetation structure is a quantitative measurement used to assess the health of vegetation in an area. Vegetation in the urban fringe region of Surakarta is dominated by types of Tectona grandis, Senna siamea, Mangifera indica, Switenia macrophylla and Leucaena leucocephala. Tectona grandis (220.02%), Falctaria moluccana (164.63%) and Pterocarpus indicus (142.55%) have the highest IVI vegetation in Karanganyar District. In Sukoharjo Regency, variations for the highest IVI were diverse with the highest IVI being Falcataria mollucana (171.49%), Tectona grandis (97.46%) and Gluta rengas (89.54%). Tectona grandis (230.99%) and Mangifera indica (145.53%) are the species with the highest IVI in Boyolali District. The high importance of Tectona grandis is based on the IVI count. The dominance of vegetation species in urban fringe is considered to be of high economic value for the community.

Sand mining has gained popularity in rural South African communities, as a result of the growing need for building materials in the surrounding villages and as a source of income for rural communities. Consequently, sand is a vital natural resource for every civilization in the world. Despite the growing dependence of rural communities on sand, communities involved in this industry will face significant obstacles if it is not regulated. The link between environmental concerns and sand mining in South Africa has remained a contentious issue and an under-researched field, despite the existence of literature indicating an increase in environmental awareness among some mining operations. Therefore, the review paper seeks to give a detailed review of t degradation of land due to illegal sand mining in South Africa’s rural areas, as well as a lack of formalization in the industry, contribute to land degradation. The development of a passive regulatory agenda for sand mining makes enforcement tough and complex. The absence of defined criteria for dealing with sand mining operations and the inability of regulatory bodies result in unscrupulous sand mining and environmental destruction. It is advised that local governments enact rules to maintain the biological beauty of their towns, even though there are now no regulations in existence. The communities in the area of the extraction sites should undergo environmental awareness training, and there should be a clear check on the regulatory bodies in order to discourage unlawful sand mining. Consequently, there is a need to regulate sand mining in both national and international rivers, and it should only be permitted after a comprehensive scientific investigation demonstrates that there will be no negative environmental impact. Greater consideration of alternatives and utilization of resources more sustainably could significantly reduce environmental impact.
