Can Korea maintain environmental standards? The implications of shifting EIA review privileges to ministerial affiliates

South Korea's environmental assessment (EA) system previously relied on the Korea Environment Institute for independent reviews of environmental impact statements. In mid-2022, review privileges were expanded to five institutions including four new organizations that are direct affiliates or subsidiaries of the Ministry of Environment. This diversification aims to improve the EA process, but concerns exist regarding the adequacy of the plans and the lack of prior preparation. The current expansion, focusing on Ministry of Environment affiliates, raises concerns about diminished autonomy and a potential regression in independent review. The authority's initiative to enhance the efficiency of the EA system through diversifying review institutions does not fundamentally address current needs in Korea. This paper argues the most urgent issues in the evolution of the current EA system in Korea. To ensure an effective EA system in the face of climate change and broader environmental challenges, reforms are needed. These reforms should prioritize strengthening consultant capabilities, ensuring independent reviews, reinstating the strategic EA function, and transitioning to a sustainability assessment system.

Toward the Institutionalization of a One Health Agenda: What the World can Learn from Bangladesh

Abstract In 2005 and 2007, prompted by Nipah and avian influenza outbreaks, respectively, faculties at Chattogram Veterinary and Animal Sciences University (CVASU) in Bangladesh initiated a civil society network of researchers in animal and human health. This network led to the launch a year later of One Health Bangladesh (OHB), a platform with membership open to multi-disciplinary scientists, practitioners, and activists. Along with continued advocacy to advance One Health agenda, OHB partnered with government, UN agencies, and other stakeholders to develop, in 2012, a National One Health Strategic Framework and Action Plan. The National Plan was later endorsed by the Ministry of Health and Family Welfare (MoHFW), Ministry of Fisheries and Livestock (MoFL), and Ministry of Environment, Forest, and Climate Change (MoEFC) followed by its implementation which introduced a three-tier multi-sectoral coordination mechanism including the establishment of a One Heath Secretariat in 2016. In 2017, an operational budget for the One Health Secretariat (OHS) was allocated by the MoHFW and three mid-level government officers from three government agencies, and the Directorate General of Health Services (DGHS), Department of Livestock Services (DLS), and Bangladesh Forest Department (BFD) were seconded to the OHS to make the Secretariat functional. OHB and the OHS now work together to advance the institutionalization process and implement One Health activities including One Health capacity building, joint surveillance, outbreak investigation and intervention, advocacy in the form of arranging dialogs, seminars, workshops, and conferences, and promoting cross sectoral and transdisciplinary collaboration, networking, and partnership nationally and internationally.

Genotypic Selection Using Quantitative Trait Loci for Better Productivity under High Temperature Stress in Tomato (Solanum lycopersicum L.)

High temperature stress affects tomato production both in tropical and sub-tropical environments worldwide. To explore genetic variation for heat tolerance in tomato, 329 transcontinental tomato genotypes were evaluated at the Ministry of Municipality and Environment (MME) greenhouses near Doha, Qatar, where the average daytime temperature was 38 °C with a big fluctuation during the tomato growth season. A preliminary phenotypic analysis identified a panel of 71 hybrid and pure-line tomato genotypes for more detailed studies. The selected subset was examined in the greenhouse using a randomized complete block design under heat stress. The materials were phenotyped for fruit size, fruit weight, fruit hardness, fruit locules, fruit set, total soluble solids (TSS), and fruit yield. Significant phenotypic differences among genotypes were observed for all the traits assessed. To explore the genetic basis of the variation among the examined genotypes, the subset was genotyped using 104 SNP markers identified in previous heat-tolerance genome-wide association studies (GWAS). Nineteen QTL-associated SNP markers could reliably select heat-tolerant genotypes in terms of better fruit yield, fruit set, and TSS. These markers are located on chromosome 1, 5, 6, 8, 9, and 12. Interestingly, two clusters of markers on chromosome 6 were linked to significant effects on yield, fruit set, and TSS under high temperature. Eighteen out of nineteen SNP markers were mapped within a gene body. Based on the phenotypic and the genotypic analysis, an elite set of five genotypes was selected for approval for heat stress environments in Qatar. The aim of the present work is to provide significant results that are exploitable not only in the Qatar region but also worldwide. Specifically, the 19 molecular markers identified in this study can serve as useful tools for breeders in selecting heat-tolerant material.

Kondisi Terumbu Karang Di Perairan Leato Selatan Kecamatan Dumbo Raya Provinsi Gorontalo

Coral reefs are one of the tropical aquatic ecosystems which have a very important function both for the organisms that build this ecosystem and the surrounding ecosystems, namely seagrass ecosystems and mangrove ecosystems. Coral reef ecosystems are coastal area resources that are very vulnerable to damage, especially caused by human behavior/surrounding communities. The aim of the research is to determine the percentage of coral cover and coral reef mortality index in South Leato waters. This research was carried out from February to March 2024, located in South Leato Waters, Dumbo Raya District, Gorontalo Province. The research uses the Underwater Photo Transect (UPT) method, where the data is processed and analyzed with CPCe software. Based on the percentage of live coral cover from each station, namely Station I of 48.53% is in the medium category, Station II of 27.56% is in the medium category, Station III of 39.97% is in the medium category. With an average live coral cover of 38.69%, it is in the medium category, referring to the Decree of the Minister of Environment No. 4 of 2001 concerning Standard Criteria for Coral Reef Damage. The percentage level of coral reef damage calculated using the Mortality Index is station I at 0.46, station II at 0.66, station III at 0.67. The average mortality index for coral reefs in South Leato waters is 0.59, falling into the high mortality index category.

Climate change and resilience of the Senegalese health system in the face of the floods in Keur Massar.

This article is based on the observation that the affected populations perceive existing community-based adaptation strategies to the health effects of floods differently. We explore the resilience of the local health system to climate change (CC) in Keur Massar (Senegal) using a monographic approach based on a qualitative survey of flooded households, health professionals, hygiene agents, community health actors, administrative and local authorities, agents from the Ministries of Health and Environment, and experts from the ecological and meteorological monitoring centre (n=72). The effects of CC on health are modulated by financial, organisational, social and cultural factors. The effects of CC on health are modulated by traditionally praised by self-centred health governance, which is often based on standardisation of problems and thus not sufficiently attuned to local contexts, especially the climate vulnerability index (CVI) of households and health structures. Despite the existence of programs to combat the consequences of CC, the notorious lack of exhaustive mapping of areas with a high CVI hinders the effective management of the health of the affected populations. A typology of forms of mobility in the context of flooding-ground floor to the upper floor, borrowing a room, renting a flat, seasonal residence-reveals inequalities in access to care as well as specific health needs management of vector-borne diseases, discontinuity of maternal, newborn and child health care, and psychosocial assistance. The article outlines how a health territorialisation based on surveillance and response mechanisms can be co-constructed and made sustainable in areas with a high CVI. Integrating this approach into national health policies allows for equity in health systems efficiently and sustainably.

Analysis of the relationship between the population size of Kalimantan orangutan (Pongo pygmaeus) and land cover changes in Central Kalimantan, Indonesia

Abstract. Openg EBL, Santosa Y, Jaya INS. 2024. Analysis of the relationship between the population size of Kalimantan orangutan (Pongo pygmaeus) and land cover changes in Central Kalimantan, Indonesia. Biodiversitas 25: 3468-3475. Land cover change, a major driver of habitat change, significantly influences the distribution of wildlife species, including the Kalimantan orangutan (Pongo pygmaeus Linnaeus, 1760) in Central Kalimantan, Indonesia. This analysis, aimed at quantitatively assessing the relationship between changes in land cover and the population of Kalimantan orangutans in 2014-2019, underscores the urgent need for orangutan conservation. Using data on the population of Kalimantan orangutans and updated Landsat images with land cover data from the Indonesian Ministry of Environment and Forestry, we conducted a multiple linear regression analysis to unveil the relationship between the two. The research results from three specific conservation area locations reveal a decrease in the orangutan population in Lamandau, with the largest increase in open land cover types, a trend largely influenced by anthropogenic factors. Conversely, an increase in population was observed in Sebangau, with the largest increase in the swamp land cover type, and population fluctuations occurred in Tanjung Puting, with the largest increase in the open land cover type. The decline in the orangutan population is attributed to anthropogenic factors and natural predators, while the population increase occurs naturally and through orangutan reintroduction activities. The analysis concludes that secondary swamp forests, bushes, and open land cover are closely related to the size of the Kalimantan orangutan population at the research location, thereby highlighting the urgency and concern for orangutan conservation.

Treatment of Domestic Wastewater in Colombia Using Constructed Wetlands with Canna Hybrids and Oil Palm Fruit Endocarp

Untreated domestic wastewater from rural areas poses significant risks to ecosystems and human health. Constructed wetlands (CWs) are a viable alternative for this wastewater treatment, enhancing nitrogen removal using substrates as carbon sources. This process is particularly beneficial for wastewater with low carbon-to-nitrogen (C/N) ratios, making the treated water suitable for agricultural irrigation. In this study, a Horizontal Subsurface Flow CW (HSF-CW) was evaluated using Canna hybrids and a mixed substrate of gravel and endocarp from oil palm fruit (EOP) as a carbon source to leverage its abundance in the region. It was also determined that the effluent complies with the permissible limits set by Resolution 1207 of 2014 from the Colombian Ministry of Environment and Sustainable Development, which establishes environmental standards for wastewater treatment to ensure environmental protection and enable safe reuse in agricultural irrigation. The key parameters analyzed included organic contaminants, heavy metals, nutrients, and microbiological indicators. Removal efficiencies of up to 91%, 94%, 98%, 52%, 73%, 78%, and 75% were achieved for BOD, TSS, total phosphorus, nitrates, nitrites, ammonium, and total nitrogen, respectively, demonstrating the CW’s strong performance in contaminant removal and meeting most standards for agricultural irrigation. Although the carbon source was not highly efficient, the overall system performance supports its viability for improving water quality and promoting sustainable agricultural practices in rural areas.

Perbandingan Tingkat Kebisingan Berbagai Bahan Peredam pada Knalpot Sepeda Motor Racing

The use of racing exhausts on motorised vehicles can cause uncomfortable and dangerous noise pollution if it exceeds the threshold set by the Minister of Environment. Based on the Decree of the Minister of Environment No 07/2009, the noise limit for motorbikes with engine capacity below 80 cc is 77 dB, 80-175 cc is 80 dB, and above 175 cc is 83 dB. This study aims to observe the comparison of noise levels of various silencer materials on racing motorbike exhausts in order to find the most effective material in reducing noise in accordance with these regulations. The noise measurement method follows the ISO 5130 standard, carried out when the engine is running idle and at engine speed range from 0 to 8000 RPM with a variety of different damping materials. The results show that at idle conditions, yellow Glasswool is the best damping material with the lowest noise level of 90.31 dBA, while Stainless wool shows the worst performance with an average noise level of 100.81 dBA. In contrast, in the 0-8000 RPM rotation condition, Stainless wool became the most superior silencer material with a noise level of 105.4 dBA, while grandma's hair Glasswool (fibreglass) became the worst with the highest noise level of 106.4 dBA. The conclusion of this study is that the optimal choice of silencer material can differ depending on the operating conditions of the racing exhaust, with yellow Glasswool being more effective at idle conditions and Stainless wool being more effective at maximum revs.

Potensi Aplikasi Bambu Sebagai Bahan Peredam kebisingan Operasional Kereta Api dengan Menggunakan Model Kristal Sonik Persegi

Noise is the unwanted sound of a business or activity at a certain level and time that can cause disturbances to human health and environmental comfort. One of the transportation activities that can cause high noise is train. The effort to reduce the noise caused by the train is to build a noise-absorbing building in the form of sonic crystals. This research aims to analyze the potential application of bamboo with a square sonic crystal model as a noise reducer for railway activities. This research method is an experimental method using the method of Ministry of Environment No. 48 of 1996. The noise absorber is made of bamboo-based material arranged with a three-layer square lattice type, a diameter of 8.7 cm ± 0.2 cm, and a height of 2 meters. From the results of this study, it was found that the day and night equivalent noise level (LSM) using the barrier was 90.70 dB, 91.20 dB, 92.09 dB at a distance of 1, 2, and 3 meters. The potential of square lattice bamboo-based sonic crystals as a building damper can reduce the noise level by 8.87 dB (8.91%). Bamboo with this square lattice can be an alternative noise dampening building in the residential area around the railroad.

Event-specific loop-mediated isothermal amplification for living modified cotton MON88701, MON531, MON15985, MON88913, and COT102

Gossypium hirsutum L., commonly known as upland cotton, is cultivated globally for natural fiber, feed, and seed oil. To enhance agricultural productivity and quality, living modified (LM) cotton has been developed and utilized since the late 1990s. Due to environmental concerns, such as biodiversity risks associated with living modified organisms (LMOs), the Korean government, including the Ministry of Environment, has been conducting LMO natural environment monitoring and post-management projects. In this study, we developed a loop-mediated isothermal amplification (LAMP) assay to detect five specific LM cotton events (MON88701, MON531, MON15985, MON88913, and COT102), which were the most abundant volunteers observed from 2019 to 2021 in South Korea. The event-specific LAMP assays for the five LM cotton events were established with a 40-min reaction time using LAMP reaction buffer, Bst DNA polymerase, and event-specific primers. The limit of detection ranged from 0.01 to 1 ng/μL. The assays' specificity and sensitivity were validated through colorimetric changes, fluorescence intensity measurements, and conventional PCR. To demonstrate the practical application of the LAMP assays, we tested 22 LM cotton volunteers collected from the natural environment in 2021. Each LAMP assay event-specifically amplified the respective LM cotton volunteers. These results indicate that the developed LAMP assays are effective tools for the efficient management and detection of LM cotton in field surveys, supporting regulatory compliance and environmental monitoring efforts.

Research on Evolution and Recommendations of China’s PM2.5 and O3 Pollution Control Policies under the Carbon Peak and Carbon Neutrality Targets

In recent years, the issue of PM2.5 and O3 pollution in China has gradually become a hot topic in air pollution control. Powerful, precise, and clear policies are important to guide the efficient control of PM2.5 and O3 pollution. However, research on PM2.5 and O3 pollution policies is very limited. Moreover, these reports have failed to identify all the specific characteristics of the PM2.5 and O3 pollution policies in China, leading to inefficient control of PM2.5 and O3 pollution. Therefore, based on the external features and internal structures of relevant policy documents, this paper conducts a detailed bibliometric analysis to elucidate the evolution of PM2.5 and O3 pollution control policies in China. The results reveal the following: (1) The PM2.5 and O3 pollution control policies in China exhibit a characteristic of “top-down cross-level response lag”, transitioning from individual pollutant control to coordinated control of PM2.5 and O3 pollution. (2) The Ministry of Environmental Protection and the Ministry of Ecology and Environment have been the two major policy issuers in China’s government, focusing on “Technology” and “Monitoring”, respectively. However, the aforementioned policies are mainly implemented by local governments, with limited interregional cooperation but an overemphasis on enterprise pollution control and emergency systems. (3) In terms of policy instruments, supply- and environment-oriented policy instruments are predominant, whereas demand-oriented policy instruments are inadequate. Therefore, it is suggested to utilize the synergistic effect of pollution reduction and carbon mitigation to achieve the goal of the “dual carbon” strategy, enhance public participation to strengthen cooperation among diverse stakeholders, strengthen cross-regional cooperation to overcome governance barriers, and reasonably optimize the use of policy instruments to form an effective combination of policy instruments.

Evaluating Surface Water Quality of Euphrates River in Al-Najaf Al-Ashraf, Iraq with Water Quality Index (WQI)

The present study illustrates the rapid pollution of Euphrates River, inwards Al-Najaf Al-Ashraf governance (Al-Kufa River) in Iraq, which is one of the most important rivers in the region. The river faces formidable pressure due to encroachments, discharge of untreated domestic and industrial waste, drainage water from cultivated orchards, and dumping of solid waste. This study was conducted to assess the temporary and locative organic pollution in the region. Water Quality Index (WQI) of the Al-Kufa river was determined according to the Canadian Council of Ministers of Environment (CCME) method by calculating seven parameters (water temperature, DO, COD, EC, TDS, turbidity, and pH) in two sampling stations. Surface water samples were collected in a period of four months (September to December) in 2023. WQI level, correlation analysis between parameters, and Iraqi and CCME drinking water specification standards were employed to classify the surface water status. The results show that the ecological condition can be classified as marginal with WQI= 49 and poor with WQI= 42 in stations 1 and 2, respectively.

Determining Water Quality Status and Assimilation Capacity of Pollutant Loads in West Lombok Regency

Babak watershed is one of the essential watersheds in Lombok Island providing water supply for irrigation, fish pool, drinking water supply, and micro-hydro power plant. Excessive human activities degrade the water quality of Babak watershed, and more pollutants are present in the water column. Thus, this study aims to determine Babak watershed's water quality status and assimilating capacity to plan effective and holistic mitigation measures properly. The study calculates the pollution index (PI) using a formula based on the Minister of Environment No.115/2003 Decree and assimilating capacity (AC) based on the Minister of Environment No.110/2003 Decree. The results found that Babak watershed is lightly polluted, defined by exceeding chemical parameters such as DO, total phosphate, nitrite, and dissolved iron (Fe). Similarly, these parameters (total phosphate, nitrite, and Dissolved iron (Fe) also reached the maximum assimilation capacity of Babak watershed to contain and self-purify these pollutants from the water column. Thus, planning mitigation and adaptation measures are required to prevent further contaminations in this watershed.

The impact of urbanization on environmental degradation in Jakarta

Background: The urbanization discussed in this paper refers to the process of expansion in the proportion of the population living in urban areas. Urbanization is seen as one of the processes of increasing population that drives the functional change of an area, from rural to urban activities. The case discussed in this paper is urbanization occurring in Jakarta city. This paper aims to examine the relationship between urbanization and the decline in environmental quality, especially in Jakarta city. Method: In assessing environmental quality, the reference used follows that set by the Ministry of Environment and Forestry, namely the Environmental Quality Index (EQI) which consists of three elements, namely the Water Quality Index (WQI), Air Quality Index (AQI) and Land Cover Quality Index (LCQI), so the variables used are WQI, AQI and LCQI. The data collection method used in this paper is secondary data collection through literature review and official data sources from related stakeholders. The collected data is then analyzed descriptively to determine the relationship between urbanization and each of these variables. Results: Based on the literature review and the results of the LCQI data used, it appears that there is a negative correlation between population growth and land cover in Jakarta Province. This condition is marked by an increase in floods and also an increase in surface temperature. In terms of air quality, this paper found a negative correlation between urbanization and AQI. However, for the condition in 2013 - 2018, a positive correlation was found between the population and AQI. Conclusion: This indicates that an increase in population is not always followed by a decrease in environmental quality. Meanwhile, in relation to water quality, population growth from the urbanization process has a significant impact on water quality in Jakarta. Novelty/Originality of this study: The development of a sophisticated and comprehensive correlation analysis method between population growth and environmental quality indicators (IKLH, IKA, IKU), which integrates spatial and temporal data, provides a predictive tool that city governments can use to monitor, manage, and plan mitigation strategies for the impacts of urbanization on the environment more effectively and proactively, and supports data-based decision-making in sustainable urban planning.

Evaluating The Effectiveness of Wastewater Treatment In the Reusable Packaging Industry: A Case Study of ALNER’S WWTP In Indonesia

The widespread use of single-use plastic packaging has become a significant environmental issue, particularly in the Global South. This study examines the innovative approach of the startup Alner, which employs a combination of electrochemical treatment and Moving Bed Biofilm Reactor (MBBR) technology in its wastewater treatment plant (WWTP) to manage wastewater generated from the cleaning of reusable packaging. Wastewater samples were collected before and after treatment, and analyzed for key parameters such as Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD5), Total Suspended Solids (TSS), oil and grease, ammonia, surfactants, and phosphates. The results demonstrated a significant reduction in all measured pollutants, with COD reduced by 99.58% and BOD5 by 99.56%. Post-treatment values for all parameters were well within the regulatory limits set by the Ministry of Environment and Forestry Regulation No. P68/MenLHK/Setjen/Kum.1/8/2016. This study underscores the potential of reuse models in reducing single-use plastic waste and highlights the importance of effective wastewater treatment in maintaining environmental sustainability. Alner's approach provides a scalable and environmentally friendly solution, setting a benchmark for similar initiatives in the industry, and supports the feasibility and sustainability of integrating advanced wastewater treatment technologies in the reusable packaging sector, offering a comprehensive solution to plastic pollution.

PERHITUNGAN EMISI GAS RUMAH KACA DALAM KAWASAN PERTAMBANGAN

Carbon emissions are one of the components of greenhouse gas (GHG) emissions in the form of carbon dioxide (CO2) which mainly comes from the use of fossil fuels and various human activities. Based on fossil fuel and industrial emissions data, in 2022 Indonesia ranked as the 6th largest carbon emitting country in the world after China, the United States, India, Russia and Japan, with 728.88 million tons of CO2e total emissions. The Ministry of Industry reported that total GHG emissions from Indonesia's industrial sector reached 238.1 million tons of CO2e in 2022. In the mining industry, GHG emissions originate from deforestation, energy use, processing, and refining, with non-renewable energy use being the largest emitter. GHG emissions from primary mineral and metal production contribute approximately 10% of global GHG emissions related to energy. Each mining industry may have varying primary sources of GHG emissions depending on the type of mine and the final product. Mining industries, as one of the major emitters, must conduct GHG inventories to understand emission sources and develop effective reduction strategies. GHG inventory activities are conducted based on guidelines provided by the Ministry of Environment and Forestry's National Greenhouse Gas Inventory Management Handbook (2012), Book II Volumes 1-4. Efforts to reduce GHG emissions can be undertaken through planting plants that have high carbon absorption and storage capabilities in mine reclamation activities, as well as using New and Renewable Energy (NRE) as an alternative to replace fossil energy.

Waste Plastic Pyrolysis Industry: Current Status and Prospects

Pyrolysis is a technology that can produce pyrolysis oil by decomposing waste plastic, and has the advantage of being able to process contaminated waste plastic that is impossible to process with other technologies. In Korea, where the amount of waste plastic is increasing and natural resources such as fossil fuels are lacking, pyrolysis technology is attracting attention under the keyword ‘urban oil field’. The Ministry of Environment of the Republic of Korea announced a ‘plan to revitalize waste plastic pyrolysis’ to increase the proportion of waste plastic pyrolysis treatment from 0.1% in 2021 to 10% in 2030. The products of pyrolysis are both fuel and plastic raw materials, but the processing consumes significant energy. Therefore, as criticism continues that the marketability and economic feasibility of pyrolysis technology is poor, questions are being raised about its environmental friendliness. Against this background, this study investigated international trends in pyrolysis technology and performed a detailed comparative analysis with other technologies from an environmental perspective. According to the results of this study, currently environmentally advanced countries are very negative about using pyrolysis oil as fuel, and the following policy directions are suggested. 1) In order to comply with the mandatory use ratio of plastic recycled raw materials and at the same time achieve eco-friendliness, it is recommended to use pyrolysis technology as a plastic recycled raw material production technology rather than fuel conversion. 2) Since pyrolysis emits more greenhouse gases than physical recycling, pyrolysis technology is used as a complementary method to physical recycling to process waste plastics that are difficult to physically recycle. 3) Since physical recycling is very important in the resource circulation of waste plastic, the development of separation and sorting technology is promoted nationally.
