Effective Waste Management in Urban Centres in South Sudan

Purpose: The objective of this study was to assess effective solid waste management in urban centres in South Sudan with special reference to Juba City Council. This included the types of solid waste generated, solid waste management practices and factors hindering effective solid waste management in relation to population growth and behavior. Methodology: The study used random sampling technique to determine a sample size of 200 respondents who were versed or partly versed with the subject in question. This included the Ministry of environment officials, City council waste management directorate, Members of parliament and the residents of Juba city council. Qualitative data was obtained from interviews using interview guides which were coded, interpreted. Further data was analyzed to give it a broader and more meaningful picture of the sample. Findings: The study findings revealed that paper and carton, yard trimmings, food, scraps, wood, glass, plastics, metal and clothes were the types of solid waste generated within the urban centres in South Sudan. The study further revealed that urban population growth significantly affects solid waste management in Juba city and poses the challenges of solid waste segregation since the waste is indiscriminately disposed of. In addition, insufficient funding led to inadequate provision of facilities and equipment for solid waste management coupled with inadequate enforcement of public health legislations and solid waste management by-laws. Unique Contribution to Theory, Policy and Practice: The study therefore recommended the use of integrated solid waste management, adequate resourcing, law enforcement and strengthening of the capacity of the Juba City/Municipal/urban councils’ policies and regulations.

Community-driven Waste Management: Insights from an Action Research Trial in Yogyakarta, Indonesia

Background Yogyakarta is in a waste emergency period. Waste management poses a significant challenge in urban areas, necessitating innovative and sustainable solutions. This article explores the Community-Based Waste Management (CBWM) approach implemented in Yogyakarta City, Indonesia, shedding light on valuable lessons from this initiative. Yogyakarta City's experience is a case study for understanding the effectiveness of involving local communities in waste management efforts. Through participatory programs, residents have been empowered to actively contribute to waste reduction, recycling, and proper disposal practices. Objective This study seeks public health-oriented household waste management options and increases public awareness about trash management while keeping public health in mind to overcome Yogyakarta's waste emergency. Methods This study employs an action research design mixed with qualitative research. Participants were members of society, government authorities (environmental and health offices), and the Yogyakarta Provincial and City Health Offices. For the trial method, participants comprised four cycles utilizing a standard random sample procedure. An in-depth interview was conducted to evaluate the procedure, and questionnaires were used to determine performance indicators for the procedure. Results Community-based action research guarantees that waste management is improved by approaching it from a public health standpoint. Waste management innovations include implementing environmental sanitation, clean and healthy lifestyles, implementing occupational health and safety concepts, sorting organic and inorganic waste, as well as innovations in household waste management infrastructure.

This idea is suitable and adaptable to the circumstances of Yogyakarta City residents.

Board governance drivers of corporate sustainability levels in private firms: evidence from Sweden

PurposeThe purpose of this study is to investigate whether board composition affects corporate sustainability (CS) levels in private firms. Additionally, the study examines a potential interplay between CS levels and CS reporting, and the impact of EU Directive 2014 / 95/EU (Non-Financial Reporting Directive [NFRD]) on resources spent on CS.Design/methodology/approachThe authors surveyed the chief executive officers (CEOs), chief financial officers (CFOs) and Environment Officers of Swedish private firms subject to NFRD, receiving 149 valid responses (a response rate 24%). The authors coded the responses using van Marrewijk and Werre’s (2003) CS levels framework. The levels are Pre-CS, Compliance-driven, Profit-driven, Caring, Synergistic and Holistic. The study then explained the CS levels with board characteristics.FindingsWhile on average the sample firms have a profit-driven CS level, the authors find that CS level is positively driven by female Chairs, female CEOs and external CEOs. Early voluntary reporting before NFRD does not explain the CS level. On adoption of the NFRD, mandatory reporters increased resources spent on CS activities and CS reporting more than early voluntary-reporters. Nonetheless, slightly over half of the sample firms reported no significant impact of the NFRD on resources spent on CS.Practical implicationsThe findings may be useful for stakeholders interested in corporate governance and CS levels. Also, the findings support further regulation such as EU Directive 2022/2464 (Corporate Sustainability Reporting Directive [CSRD]).Social implicationsIn private firms, female leaders are likely to play a significant role in driving altruistically motivated CS practices.Originality/valueThe focus is on private firms in Sweden which, unlike those in other jurisdictions, were subject to NFRD. Methodologically, the use of a survey provides an alternative to the previous heavy reliance on archival research.

In this research, what is used to create an attendance application is to use programming languages such as HTML, CSS, and PHP, and to make connections only by creating a database that will be used in creating what I will create.

The effect of environmental centralization: An assessment of China's environmental vertical management reform below provincial level

To strengthen the top-down supervision over local environmental management, China has gradually initiated environmental vertical management reform (EVMR) below provincial level since 2016, which empowers provincial environmental agency to replace municipal government to directly administrate municipal environmental agencies. As the largest environmental centralization reform in China since the opening and reform, the effect of EVMR below provincial level on environmental quality and the underlying mechanisms remain relatively underexplored. Taking air quality as the indicator, one of the most prominent environmental issues in China, and using panel data of 255 municipalities during 2011–2021 and staggered difference-in-differences model, this research finds that that averagely, the reform reduced municipal annual PM2.5 concentration by about 8.03 %. However, the effect was not significant until the fourth year after the reform. In addition, the reform effects were heterogeneous for cities with different levels of resource endowments, attention of high-level authority, and economic growth pressure. Further analysis shows that the reform has strengthened the working incentive of municipal environmental agency by increasing their budget and enhancing law enforcement power. However, the reform has failed to boost the environmental attention of municipal governments, which are inclined to view environmental agency as an outsider rather than collaborator. Moreover, it is found that in part of cities, the personnel management along with the EVMR is still lagged and municipal environmental agency is still subject to the intervention of municipal government, which negatively affect the working enthusiasm of the environmental officers and thus the reform effect. Finally, this paper proposes corresponding suggestions to further improve the reform effect.

DO WE NEED SOCIAL EWOM TO BRING UP BRAND ATTITUDE AND PURCHASE INTENTION?

This study aims to analyze the application of human resource management strategies at the Bintan Regency Environmental Office. This research is a study that uses qualitative research. The results showed that the implementation of human resource strategies at the Bintan Regency Environmental Office has been implemented but must be developed again because basically human resources have many differences for each individual. Planning at the Bintan Regency Environmental Office has been done well through planning, implementation, organizing. In terms of organizing, human resources owned by the Bintan Regency Environmental Office are still developing and training in order to implement the policies contained in the Bintan Regency regional regulations because the Bintan Regency Environmental Office is engaged in the government sector that regulates government regulations through policies that have been regulated in law.

PERSUASIVE COMMUNICATION STRATEGY OF BANDAR LAMPUNG CITY ENVIRONMENTAL OFFICE IN WASTE MANAGEMENT

ABSTRAC Waste generation continues to increase rapidly along with population growth and changes in people's diets and lifestyles, thus affecting the amount of waste produced, the type of waste and the characteristics of different waste. One of them to minimize the impact of increasingly accumulated waste can be done through inviting the community to participate in maintaining the cleanliness of the environment through persuasive communication strategies to the community. The purpose of this study was to find out the persuasive communication strategy of the Environmental Office in waste management, a study in Kampung Baru Tiga Kelurahan Panjang Utara. This research uses qualitative methods. Data were collected obtained from interviews, observations and field notes. The result of this study is that Waste Management has not been carried out properly due to low public awareness and concern about proper waste management. To increase public awareness and public concern for the environment and waste management, the Environmental Office and Village Apparatus have conducted education to the community in the form of socialization, counseling, and advertisements about waste management to be useful including compost and ecobricks. Handling waste problems needs to increase public awareness of the importance of environmental cleanliness by the Environmental Agency as the main agency responsible for waste management must establish good relations with the community so that the waste management program is in accordance with its goals.

Academia's Role in Climate Action: Enhancing Awareness and Reducing Environmental Impact of Academic Events

A clean environment is vital for both population health and the well-being of our planet (Brusseau et al., 2019). In-person gatherings, like academic conferences, significantly contribute to carbon emissions that harm the environment, highlighting the importance of finding opportunities to reduce these emissions (Tao et al., 2021). Cognizant of the environmental cost of our annual national in-person research team gathering, our team sought to minimize the environmental impact of our 2023 gathering while raising awareness among team members. Our actions included using reusable tableware, composting food waste, and hosting an education session by the local environment office. Not only did our efforts increase awareness among gathering attendees about the importance of considering environmental impact reduction opportunities in their work, but they also catalyzed similar efforts at two national conferences. Our team took the lead in developing an evaluation of the environmental impact of each national conference and surveyed over 150 conference attendees. We collected demographic information, travel mode to the conference, and attitudes about environmental harms via a digital conference application. We also observed environmental actions implemented by event organizers and venue hosts. A carbon emission score and frequency distributions of attitudes surrounding the environment were calculated. Where possible, a food waste assessment was conducted. Findings showed that event organizers made efforts to minimize the environmental impact of their event by selecting a venue whose management was interested in collaborating; by encouraging attendees to carpool and use reusable water bottles; by serving plant-based meals, and by minimizing single-use products. Findings also revealed that most conference attendees consider it important to reduce the environmental impact of their professional lives. Given the value of face-to-face interaction in facilitating knowledge exchange (Chan et al., 2023), it is important that organizers continue to make efforts to reduce carbon emissions when planning events.

Прокурорский надзор за исполнением законов в сфере охраны окружающей среды в Арктической зоне Российской Федерации

Federal executive authorities, the Prosecutor's Office of the Russian Federation, the Environmental Prosecutor's Office of the Arctic Zone of the Russian Federation (AZRF) pay special attention to the state of the Arctic environment. However, the situation in this region is far from normal. The results of the prosecutor's inspections indicate the presence of numerous violations of environmental legislation in the field of subsoil use, marine and river transport, construction, land use and reclamation, and the elimination of accumulated damage as a result of past years. There are cases of industrial safety violations. A serious problem for the Arctic regions is the lack of an effective waste management system in the Arctic zone. Global warming and disruption of the Arctic environment leads to climate change and can lead to even more tangible and severe environmental consequences. The Environmental Prosecutor's Office has a significant impact on correcting the situation in the Arctic, which conducts inspections of enterprises, organizations and citizens for compliance with environmental legislation, prevents and suppresses environmental offenses, and ensures compliance with environmental protection and environmental management requirements.

Collaborative Communication of Environmental Activists in Addressing Waste Management Issues in South Tangerang

This study analyzes the effective collaborative communication model among environmental activists addressing waste management issues in Ciputat Subdistrict, South Tangerang. Using a qualitative case study approach, data were collected through in-depth interviews, participatory observation, and document analysis, supplemented by Participatory Action Research (PAR) techniques. Social network analysis was conducted to map interactions among 42 stakeholders. Key findings reveal that actors with low Constraint and high EgoBet, such as the Head of the Environmental Office, Subdistrict Heads, and key community leaders, hold significant influence and control within the social network, facilitating communication and coordination. However, challenges include uneven group involvement, imbalanced role distribution, limited access to information, and insufficient consultation. Recommendations include increasing the engagement of less active groups, redistributing roles more equitably, enhancing transparency and information access, and strengthening expert consultation. These strategies are essential for improving collaborative communication and achieving a more integrated and sustainable waste management system.

Abundance and Parasitic Load of Housefly (Musca Domestica) in Amansea Area of Anambra State, Nigeria

Houseflies (Musca domestica) are major transmitters of pathogenic organisms to humans worldwide. This study was carried out to determine the relative abundance of housefly and its parasitic load in four different sites in the Amansea area of Anambra state, Nigeria. The housefly samples were collected with the aid of fly trap and sweep net and analyzed using sedimentation methods. Data obtained was calculated and expressed as simple percentages while chi-square was used to test for differences in prevalence rates of parasites in the study areas. Out of the 259 houseflies examined, 74 were infested with a prevalence of 28.57%. Houseflies were more abundant in the abattoir 92(35.52) followed by market area 71(27.41%), refuse dump sites (19.69%) while holy family hostels recorded the lowest abundance (17.37) (P=0.000). Houseflies infested with parasites were mostly found in holy family hostel 31(68.89) while the market area had the least infested house flies 5(7.04%). Two protozoan parasites (Entamoeba histolytica and Entamoeba coli) and two nematodes (Strongyloides stercoralis and Ascaris lumbricoides) were the parasites seen from the microscopic examination of samples. E. histolytica (7.61%) and E. coli (5.43%) were the parasites seen in Abattoir while S. stercoralis (7.04%) was the only parasite in the market area. E. histolytica (17.78%) and A. lumbricoides (51.11%) were seen in holy family hostel while E. coli (11.76%), S. stercoralis (7.84%) and A. lumbricoides (31.37%) were the parasites recovered from the houseflies in the Refuse dump site. The infestation of houseflies in the area is a threat to human health due to their ability to act as mechanical vectors for transmission of infectious pathogens. Hence, proper disposal and prompt removal of waste by environmental officers should be prioritized in the area as well as mass education of the public on the health implications of poor hygiene and poor sanitary practices.

The threshold at which a meteor shower becomes hazardous to spacecraft

Although the risk posed to spacecraft due to meteoroid impacts is dominated by sporadic meteoroids, meteor showers can raise this risk for short periods of time. NASA’s Meteoroid Environment Office issues meteor shower forecasts that describe these periods of elevated risk, primarily for the purpose of helping plan extravehicular activities. These forecasts are constructed using a list of meteor shower parameters that has evolved over time to include newly discovered showers and incorporate improved measurements of their characteristics. However, at this point in time, more than a thousand meteor showers have been reported by researchers, many of which are extremely minor, are unconfirmed, or lack measurements of critical parameters. Thus, a comprehensive approach is no longer feasible. In this report we present a quantitative criterion for a potentially hazardous meteor shower and apply this criterion to the list of established meteor showers in order to determine which showers should be included in our annual forecasts.

Investigating the effect of different smells in the indoor built environment (office) on human emotions using a mixed-method approach

Despite numerous studies highlighting the impact of smells on humans, there has been a notable lack of attention to ambient smell within the discipline of architecture. To address the gaps, a systematic methodology was designed to investigate the impact of the indoor-built environment's smell on human emotions. In this experiment, 14 adults (7 women and 7 men) are exposed to the smell of jasmine and rotten orange peel in two identical rooms. The EEG analysis revealed increased theta band power in frontal regions and increased alpha power in frontal and occipital areas when participants were exposed to the jasmine scent. Gamma activity in the frontal regions increases with exposure to the smell of rotten orange peel. Participants reported that the smell of jasmine was pleasant, leading to pleasant emotions, interest, enjoyment and a sleepy state. However, the smell of rotten orange peel led to unpleasant emotions, discomfort and annoyance for participants.

Understanding the nexus between traditional brick-making, biophysical and socio-economic environment of Goma Division, Mukono Municipality, Central Uganda

This study aimed to evaluate the environmental and socio-economic impact of traditional brick-making in Goma Division. The research methods included semi-structured questionnaires, key informant interviews, field observation, and focused group discussions. The results indicated that traditional brick-making is causing harm to the biophysical environment in the form of the degradation of wetland vegetation and deforestation (100%), landscape deformation (85%), air and water pollution, whereby DO had reduced by 19.8%, BOD, pH, TSS, TDS, EC and turbidity had increased by 3.8±0.9 ppm, 1.2±0.1, 89.4±0.1 mg/L, 18±0.9 ppm, 70±0.7 µS/cm, and 264±44 NTUs, respectively. Water pollution loads varied from point to point of sampling significantly at p<0.05, with the highest loads found at the tail end or downstream of the site but lowest at a point upstream of the clay mining site. The socio-economic analysis showed that the benefits of brick-making outweigh the costs in terms of magnitude, except for the frequency of responses. All respondents indicated that brick-making had created employment, while 87% reported an improvement in their standard of living. However, the activity is associated with accidents that can result in loss of life or bodily injury. It was concluded that Mukono Municipal Environmental Officers should monitor brick-making mines and site activities to prevent the creation of open pits and caves. The environment should be treated as a borrowed asset to ensure sustainability. The study suggests that financial support and awareness should be available to clay miners and brickmakers to ensure sustainability.

Arithmetic vs. Weighted Means in Fish Fillets Mercury Analyses.

Mercury (Hg) analyses in species of fish are performed for two reasons: (1) to safeguard human health; and (2) to assess environmental quality, since different environmental changes may increase the Hg concentrations in fish. These analyses are important since both natural and human activities can increase these Hg concentrations, which can vary extensively, depending on the species, age and catching location. Hg-contaminated fish or other marine foodstuffs can be only detected by chemical analysis. If the aim of Hg analysis is to protect the health of marine food consumers, researcher workers must consider the location where the fish were caught and interpret the results accordingly. Health and environmental officials must appreciate that in specific places, local people may have a daily diet consisting entirely of fish or other marine foods, and these individuals should not be exposed to high concentrations of Hg. Regional and national health and environmental officials should follow the recent guidance of international organizations when drawing their final conclusions about whether the products are safe or unsafe to eat. Correct statistical calculations are not always carried out; so, too high Hg amounts could be presented, and fish eaters could be protected. This work has been conducted to show the differences in Hg concentrations between weighted (weighted with fish weights) and arithmetic means. Thus, the mean that is only weighted also includes the Hg content in fishes; so, the exposure to Hg can be evaluated.

Associations of community knowledge, perceptions, and practices related to zoonotic disease with sociodemographic factors in and around Chiro Town, Eastern Ethiopia: a cross-sectional study

BackgroundZoonoses are infectious diseases that are transmitted from animals to humans. Studying the knowledge, perceptions and practices of communities related to zoonoses and the associated risk factors is crucial for effective control and prevention. This study aimed to assess the knowledge, perceptions, and practices of respondents on zoonoses and the associated risk factors in and around Chiro town, Ethiopia. Zoonotic diseases, such as rabies, anthrax, bovine tuberculosis, and brucellosis, pose a direct threat to health and livelihoods in the communities where they occur. These diseases emerge due to a combination of human-animal interactions, migration, and contact with wildlife and their respective parasites and vectors. Hence, recognizing residents’ perceptions, knowledge, and practices is crucial for effectively minimizing risks.MethodsA cross-sectional study was conducted from January 2020 to July 2021 in and around Chiro town using a pretested close-ended questionnaire. A total of 350 respondents were selected using simple random sampling methods. The questionnaire included information on the sociodemographic status of the respondents and questions concerning the knowledge, perceptions, and practices of the participants regarding the selected zoonotic diseases. The associations of knowledge, perceptions, and practices related to zoonoses with zoonotic risk factors were analysed using chi-square tests.ResultsThe study revealed that 82.9% of the respondents had knowledge of bovine tuberculosis, followed by knowledge of rabies (80%), knowledge of anthrax (45.1%), and knowledge of brucellosis (24.3%). Males had greater knowledge of bovine tuberculosis (84.8%), followed by rabies (79.8%) and anthrax (48.6%), while females had greater knowledge of brucellosis (23.6%). The most cited source of information was radio (68%). Most respondents mentioned the outbreaks of rabies (62.5%), bovine tuberculosis (53.2%), anthrax (35.6%), and brucellosis (15.7%). Respondents with higher educational levels and urban residents had more knowledge of zoonoses. More than 75% of respondents had a good perception of the transmission of zoonotic disease from animals, and the practice of consuming raw milk or raw/undercooked meat and sharing the same house with animals was high.ConclusionThe majority of respondents reported that they had knowledge of bovine tuberculosis and rabies, but lower knowledge and perceptions were reported for anthrax and brucellosis. These findings illustrate the need for collaboration among animal, human and environmental health offices in one health approach to prevent and control zoonotic disease.

Ensuring Community Development Sustainability on Biodiversity Park Development Plan

Abstract The development of biodiversity parks is increasingly being encouraged as an ex-situ effort to conserve biodiversity in Indonesia. One of the cities that are attempting to build this biodiversity park is Cimahi City in West Java. The development of the biodiversity park will not only be related to bio-physical environment aspects, but also includes other aspects including social, economic, cultural and policy. This article aims to describe the local community’s perception of the development of a biodiversity park, and to assess the community’s readiness in its development. The study that underlies the writing of this article was carried out by applying qualitative cum quantitative design by conducting a survey of 100 community members, conducting in-depth interviews with a number of resource persons and conducting field observations. The results of the study show that because of their ignorance, most of the community members perceive that the construction of the biodiversity park has no risk in their lives. This is supported by measuring the level of community readiness for the construction of a biodiversity park which is in the denial/resistance stage. The communities have no motivation to act on issues and feel that there is nothing they need to do and they should not do anything. Therefore, to ensure the sustainability of the biodiversity park in this location, the proponent (Environment Office of Cimahi City) must conduct intensive socialization, involve local communities in every stage of development, make community members part of the management of the biodiversity park, and as carefully as possible identify various business opportunities and potentials that can be done by the affected community in the location in order to make them be independent.

Semi-supervised urban haze pollution prediction based on multi-source heterogeneous data

Particulate matter (PM) is defined by the Texas Commission on Environmental Quality (TCEQ) as “a mixture of solid particles and liquid droplets found in the air”. These particles vary widely in size. Those particles that are less than 2.5 μm in aerodynamic diameter are known as Particulate Matter 2.5 or PM2.5. Urban haze pollution represented by PM2.5 is becoming serious, so air pollution monitoring is very important. However, due to high cost, the number of air monitoring stations is limited. Our work focuses on integrating multi-source heterogeneous data of Nanchang, China, which includes Taxi track, human mobility, Road networks, Points of Interest (POIs), Meteorology (e.g., temperature, dew point, humidity, wind speed, wind direction, atmospheric pressure, weather activity, weather conditions) and PM2.5 forecast data of air monitoring stations. This research presents an innovative approach to air quality prediction by integrating the above data sets from various sources and utilizing diverse architectures in Nanchang City, China. So for that, semi-supervised learning techniques will be used, namely collaborative training algorithm Co-Training (Co-T), who further adjusting algorithm Tri-Training (Tri-T). The objective is to accurately estimate haze pollution by integrating and using these multi-source heterogeneous data. We achieved this for the first time by employing a semi-supervised co-training strategy to accurately estimate pollution levels after applying the U-air system to environmental data. In particular, the algorithm of U-Air system is reproduced on these highly diverse heterogeneous data of Nanchang City, and the semi-supervised learning Co-T and Tri-T are used to conduct more detailed urban haze pollution prediction. Compared with Co-T, which train time classifier (TC) and subspace classifier (SC) respectively from the separated spatio-temporal perspective, the Tri-T is more accurate with a and faster because of its testing accuracy up to 85.62 %. The forecast results also present the potential of the city multi-source heterogeneous data and the effectiveness of the semi-supervised learning. We hope that this synthesis will motivate atmospheric environmental officials, scientists, and environmentalists in China to explore machine learning technology for controlling the discharge of pollutants and environmental management.
