Purposive sampling was conducted to focus the research on plots with frequent landslide occurrences. Out of the 20 identified landslide-prone sites, a random sampling method was used to ensure representative data collection with a 40% sampling intensity. Data were collected through direct observation, transect walks, and household surveys conducted in areas prone to landslides. Additionally, discussions were held with key informants, the technical team, and experts in the field to validate the collected data. In Bagnaskali rural municipality in the year 2020, six households reported damage, two cases of death occurred, 24 livestock fatalities were recorded, and there was damage to cultural heritage due to landslides, resulting in social losses. Affected communities also incurred compensatory losses ranging from NRs 10 to 50 lakhs due to the destruction of water resources, road blockages, and agricultural land damage. As mitigation measures for landslides, the municipality applied civil engineering techniques such as gabion walls, masonry, culverts, check dams, and reinforced concrete (RCC), as well as bioengineering techniques including plantation, wattling, and brush-layering. Civil engineering techniques were prioritized for mitigating landslides, with bioengineering serving as a supporting base. Plots where both civil and bioengineering techniques were employed together exhibited greater slope stability and reduced vulnerability. Therefore, it is recommended to use mitigation techniques that stabilize slopes and reinforce the soil to control landslide hazards effectively. To successfully reduce landslides and protect vulnerable communities, comprehensive policies, laws, and investments are required. Technical and financial assistance from governmental and non-governmental sectors is essential to minimize the impacts of landslides and implement the most effective mitigation techniques for landslide control.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, solutions to these problems cannot be achieved without rational planning decisions and cannot be attained without the basic understanding of the urban transport system. This study was carried out to assess commuter trip generation in Gboko town, Benue State with a view to estimate long-range future travel demand that would accommodate future transportation needs. Trip generation data was collected from 440 households using questionnaire and travel diary. The information from questionnaire and travel diary was used to prepare the origin-destination matrix, and gravity model was used to translate trip distribution into trip length frequency. Work trip had the greatest trip percentage (%) share among other trip purposes and was proxy for trip distribution. The 25-minute work trips dominated the urban trip pattern in Gboko town with 17.01 % annual increase. It implied that people would take much longer time and distance to reach their destination in Gboko town due to the large expanse of the town, or due to deficiency in public transit facilities and poor road infrastructure. Trip generation and distribution models for Gboko town provided accurate scenarios of the current travel pattern in the town and aided in forecasting future travel situations in the study area. The study recommended that urban transportation policy should encourage provision of public transit buses, incentives for public transit users and improve on the road network system to shorten the trip length frequency of the town.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study used 10 years daily rainfall (2012–2021) and 30 years monthly rainfall datasets obtained from six meteorological stations. Other climate parameters of Sea Surface Temperature (SST), Winds, Relative Humidity and Vertical Velocity having temporal resolution of 30 years (1992-2021) were also used. Rainfall seasonal variability was analyzed using Climatological mean and Empirical Orthogonal Function (EOF) analysis, onset and cessation dates was calculated using Cumulative percentage anomalies. The composite analysis was taken to examine the atmospheric circulation anomalies associated with OND seasonal rainfall. The study revealed that; OND season is characterized by normal to moderate rainfall variations from region to region with its peak marked at November (mid-season). Despite the slight differences over both Islands, average onset dates occur on third dekade of October (22nd – 25th) and cessation dates on the second dekade of December (i.e.10th -12th), indicating a maximum duration of 55- 60 days and makes a cycle of the short rains. The atmospheric circulation anomalies of SST, Winds, Relative Humidity and Vertical Velocity during wet years are linked with low level unstable moist winds originated from Congo basin. These anomalies are organized and converges with maritime north easterly winds from the Indian Ocean (mostly over the northern coast of Tanzania, including Zanzibar) and becoming a potential cause for rainfall during the season, while during dry years, the winds diverge as a result of dryness over the region. Therefore the results indicates that convergence (divergence) of the northwesterly to westerly, easterly and southeasterly flow contributed to the early(late) wetness (dryness) over Zanzibar and its surroundings. The study results will help to enhance the improvement of short rains seasonal onsets and cessations forecasts and improve the socio - economic activities over Zanzibar and Tanzanian at large.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136079942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to measure snail abundance in Biltongi-Narayanparabeel in the Natore district. The objective was to establish the population density of snails using the CMR (Capture-Mark-Recapture) method in four sections of the Biltongi-Narayanpara beel between August 2022 and February 2023. Snail samples were collected from four sampling sites, each located in different areas: one near agricultural land, one in the shallows, and one in the middle of the deepest part of the beel. The plot with the highest overall mean population density in terms of CMR for the presence of snails was plot 3 (33.25 ± 2.75), while the field with the lowest density was plot 4(22.75 ± 2.22). The biomass showed only slight variations across the different habitat categories. This is likely due to the presence of many young snails in shallow areas, whereas young snails in nearby regions were nearly nonexistent.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can affect the performance and carrying capacity of the land in the watershed. The purpose of study was to evaluate the performance of watershed management and analyze the land-carrying capacity based on indicators of land. The parameters analyzed were the percentage of critical land area, the percentage of vegetation cover, and the erosion index. To obtain the data needed for the study, both primary and secondary data were used. Primary data was obtained through the overlay of the base map to obtain a map of critical land, making land cover maps, and calculating erosion prediction and carrying capacity analysis of the Wanggu Watershed. Secondary data was obtained from related agencies in the form of critical land data, land cover data, literature, policy documents, and study reports that are relevant to watershed management performance. The results of the study showed that the percentage of critical and somewhat critical land area in the Wanggu Watershed is 16.07 percent, which means that this value still qualifies as high category critical land recovery. The percentage of vegetation cover, especially forest cover, is 27.10 percent, which is still in bad condition. The average erosion index value is 2.00, which is high. Based on these three parameters of land condition indicators in the Wanggu Watershed, the performance of watershed management has a poor land carrying capacity category with a value of 50. Overall, the study highlights the need for better management and conservation of the land in the Wanggu Watershed to improve its performance and carrying capacity.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134912970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can originate from various sources, such as road traffic, air traffic, railways, construction, using loudspeakers, industrial operations, and even household appliances. The purpose of the study was to review noise pollution and its effects on human health in Rajshahi City, Bangladesh. Most of the studies identified that the main source of noise pollution in the city is road traffic noise. The city is at a crossroads with prominent national as well as educational institutions like Rajshahi University, Rajshahi College, Varendra Museum, Bank of Padma River, Rajshahi University of Engineering and Technology, Hospital and Diagnostic Centre, BSCIC Industry, and numerous other educational institutions. All studies showed that noise pollution levels higher than the recommended acceptable limits were detected in various areas. Exposure to high levels of noise causes stress on human health, such as auditory, hearing, and nervous system damage, reducing productivity, insomnia, sexual impotency, respiratory, cardio-vascular, neurological, and outing damages, and limiting human life. It is recommended that affected sites develop a practical management approach for reducing noise pollution.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134913152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This province consists of several regencies and cities that already have their own waste management systems. Ogan Ilir Regency is one of the districts that has its own waste management system, but it has not run effectively because the waste retribution has not been optimally implemented. This writing paper aims to analyze potential sources of waste retribution, analyze aspects of willingness to pay and recommend new amounts of waste retribution in accordance with existing circumstances. The research method used is in the form of surveys, observations and interviews with the intended respondents. The new levy analysis is based on Regulation Number 7 of the Indonesian Minister of Home Affairs (Permendagri) for 2021. The findings revealed that there were various possible waste retributions emanating from the market sector of IDR 437,635,000, however only IDR 85,144,500 were realized.
