Abstract

Most   studies valuation that have been described previously including forest ecosystems do not see the forest ecosystem services as natual capital / natural assets and even the socio-ecological context. The implication is that forest ecosystem services are considered as an economic asset / economic capital.   the concept of value used in the valuation is the concept of the value of output.  Though the forest ecosystem services has the characteristics of a sustainable dynamic and as part of the life supporting system including the ability resilience and self-terrific capacity. So that the forest ecosystem is no longer seen as economic assets, but with the characteristics of the dynamic and sustainable forest ecosystem is seen as natural or natural capital assets. The current perspective marginalize other forest ecosystem functions, such as socio-economic functions. Whereas the concept of an insurance value of forest ecosystems is not just the case as seen from the perspective as natural capital, but the role of social values in maintaining the sustainability of forest ecosystems is crucial, as reflected by the presence of heritage value, and existence value. So that the insurance value of the forest ecosystem occurs because the forest ecosystem serves as a natural asset / natural and social capital assets / social capital.

Abstract

Almost all forest areas in the districts / cities in West Kalimantan experience reduced area. Reducing the area of forest area or deforestation can, of course, have a detrimental impact on the environment which in turn can disrupt the sustainability of development itself. Deforestation has ecological, economic and social impacts. The higher the rate of deforestation, it will cause the potential impact will also increase. West Kalimantan experienced a fairly high level of deforestation. This gives an indication that the impact caused by deforestation in West Kalimantan has a relatively high potential. In other words, deforestation causes losses including economic losses. Related to this, the research question is how much economic value is the loss caused by deforestation in West Kalimantan? This research has 2 (two) objectives: first, calculating the economic costs of deforestation in West Kalimantan during the period 2009-2015, and second, analyzing the effect of the economic costs of deforestation on West Kalimantan's GDP during the period 2009-2015. Based on the data base for the period 2009 to 2015 and using the benefit transfer technique, this research has found that the highest economic losses occur in the secondary production forest and the lowest in the conservation forest area. Furthermore, during the period 2009 to 2015, this study has found that the highest economic loss value occurred in 2013 and the lowest occurred in 2011. Overall, the value of economic losses in the form of a combination of depletion and degradation provides a less significant reduction on the value of the forestry sub-sector GRDP in West Kalimantan.

Abstract

PT Hutan Mulya is one of the companies engaged in natural forest management, carrying out logging activities that cause changes in the value of species diversity in the remaining stands (LoA). There are 651 individuals of 87 plant species in the LoA area (2016 and 2016) and 63 plant species in virgin forest areas, so there are a total of 32 plant groups. The highest Importance Value Index is found in Meranti Merah (Shorea leprosula Miq) and Suhi (Shorea atrinervosa Symington) in virgin forest areas, while in the LoA area it is dominated by the Jambuan (Syzygium Gaertn) species because it is a source of animal feed and is not produced by companies. The diversity index of tree species, poles, and saplings in virgin forest is high (>3.00), whereas in the LoA area (2016 and 2022), the level of trees is high (>3.00), the level of poles is medium (1.00–3, 00), and the level of saplings for LoA 2022 is low (1.00<). Meanwhile, the virgin forest similarity index and LoA (2016 and 2022) are in the same or medium category, between 0.31 and 1.00.

Abstract

This study aims to determine how much carbon stock is stored in logged-over areas by comparing carbon stock in virgin forests. Calculate potential biomass, carbon, carbon dioxide uptake, and economic value of CO2eq uptake in the Logged area of PT Hutan Mulya using purposive sampling data collection techniques for each plot and non-destructive methods through allometric equations. The highest carbon stock potential is in the tree-level diameter class and the location with the highest carbon stock is in the virgin forest area. Meanwhile, the logged area based on the company's establishment from 2011–2022 covering an area of 14,583 ha has a carbon stock potential of 772,537 tons C to the carbon dioxide storage value of 2,835,210.57 tons CO2eq. Based on the assumed price of USD 4.5, the potential economic value of carbon obtained by the government through carbon sales tax is IDR 85,056,317,100. The net profit obtained by the company is IDR 109,494,570,499.42. In contrast, the potential net economic value of the carbon business project scenario results in a combined logged area and virgin forest area of IDR 160,960,838,842.31 for the company and IDR 125,035,753,500 for the government.

Abstract

The circular economy represents a groundbreaking economic model that transforming waste into valuable products, potentially benefiting regional and national economies. This research explores the correlation between household waste management and its impact on environmental degradation and public health. Employing the System Dynamics method, the study delves into the intricacies of real-world system behavior, examining causal links and interrelationships within a system of interconnected sub-systems. Utilizing mental data, including scientific publications, mass media news, and expert opinions, alongside quantitative time series, the research focuses on the limitations of household waste management in addressing air and water pollution, posing potential health risks. Findings indicate a connection between population growth and increased waste generation, predominantly from residential sources. Unmanaged waste creation threatens air and water quality, emphasizing the importance of waste management in minimizing pollutants for improved public health. Aligning with the circular economy's 3R concept, effective waste management not only mitigates environmental impact but also holds the potential to enhance income generation. The circular economy's recycling and green entrepreneurship promotion can stimulate investments, fostering job creation. Collaborative efforts between governments and business owners can further support distribution and marketing channels, encouraging local self-sufficiency

Abstract

The circular economy is an innovative economic model that converts waste into valuable products, while offering substantial benefits for both regional and national economies. This study investigated how the household waste management practices affected environmental degradation and public health using the System Dynamics technique. The study drew on various sources, including mass media, expert opinions, time series data, and scientific publications, to assess the effect of waste on water, air, and public health quality. The findings indicated a link between population growth and the increased waste generation, particularly from the domestic sources. The unmanaged waste poses a threat to air and water quality, while highlighting the need for an improved waste management. A 3R approach (Reduce, Reuse, and Recycle) in the circular economy offers clear environmental and economic benefits, such as the reduced environmental impact, the increased income generation, and the enhanced investment and job creation. Additionally, the circular economy promotes the recycling and green entrepreneurship, while boosting investment and job creation. Collaboration between governments and business owners strengthens local distribution and marketing, enhancing local self-sufficiency. In summary, the adoption of a circular economic model offers substantial and wide-ranging benefits for economies at both the regional and national levels.    JEL Classification: K32; O44; Q50
