However, its social impacts on vulnerable population in deprived communities have been largely ignored. Consequently, this study examines the social-economic impacts of energy poverty among women and students in Esa Oke, a hilly and rural and energy-deprived community in southwestern Nigeria. A cross-sectional survey design approach was adopted, while purposive and random sampling technique was used in selecting respondents. Findings from the study revealed differences in energy consumption behaviour of women and students in rural settings; while women adopt traditional biomass for cooking, students adopt modern energy services. Additionally, the impacts of poor energy access differ per women and students. For instance, on one hand, the use of traditional biomass significantly affects rural women's health, as the majority (95%) of women respondents reported exposure to emissions through indirect combustion of fuelwood. On the other hand, students' academic performance and academic activities were significantly disrupted due to the poor electricity supply in the area. Based on the foregoing, the study recommends an inclusive rural energy policy that captures all social groups affected by energy poverty.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74148508","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, most researches on resource conflicts among different users, could not see the primacy of looking into these conflicts from the angle of their socio-economic and political causes. This paper among other things sought the socio-economic and political triggers of renewable natural resources conflict in Southeastern parts of Nigeria. Data were collected from 300 crop farmers purposively selected from three States - Imo, Abia and Enugu, using structured questionnaire and oral interview. Percentage and mean were used to analyze the collected data. The renewable natural resources considered in the study area were water, crop land, forests, and fishers/marine resources among others. The socio-political drivers of renewable resources conflict includes demand induced scarcity (87.7%), environmental degradation (83.3%), migration of people (91.6%) and unclear rights (85.3%). The study found that to reduce the occurrence of natural resource conflicts, following measures should be in place; reducing vulnerability to resources scarcity (M=3.57), increased availability of scarce resources (M=3.60), discourage/stop degradation (M=2.50), good governance framework (M=3.36) and effective resource sharing agreement (M=3.56) among others. It is recommended to resolve the natural resource conflicts which can be achieved by equal distribution of resources, clear rights to resources and good land governance.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75465177","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}

There exist numbers of hazardous pollutants in environment that are required to eradicate for sustainable use of natural resources. To overcome these pollutants researchers introduced bioremediation with microorganisms. This paper has been prepared by collecting data from various research articles to show numerous applications of bacillus species for sustaining environment. The article is unique from other research studies as it elaborates removal of different pollution causing elements such heavy metals, soil contaminants, removal of dye contaminants from the environment. Although there are large numbers of microbial species to degrade pollutants but according to recent researches, Bacillus is more prominent among all bacterial species. Researchers have proved that Bacillus are safer and cheaper source for conserving environment and reduce toxics from environment. Removal of heavy metals such as cadmium, nickel, copper can be done with the help of Bacillus cereus. In waste water treatment, Bacillus licheniformis and Bacillus acidophilus are also responsible for reducing nitrogenous components like phosphates, nitrites and ammonia.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90186739","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, growing food in cities is faced with many challenges like food contamination. Past studies on leafy vegetables focused on vegetables cultivated in urban centres. However, this paper aimed to determine and compare the level of heavy metals concentrations in soil and leafy vegetables in Urban Expressway Farms (UEF) and Peri-urban Road Farms (PRF) in Lagos, Nigeria. These two locations were purposefully selected. Soil Auger was used to drill holes to the required soil depth to collect soil samples. Sample of Amaranthus hybridus, Celosia argentea and Corchorus olitorius were collected using “envelope” principle. Pb, Cd and Mn residues in the samples were digested and determined using Atomic Absorption Spectrophotometer. The collected data were analysed using mean, standard deviation and Analysis of Variance. The mean pH value for UEF soil is 6.5 while PRF soil is 6.6. The highest Pb (0.93±0.06) was recorded in Celosia argentea at UEF. The highest mean concentration of Cd (0.51±0.11) was recorded in Amaranthus hybridus at UEF. The highest concentration for Mn was recorded in Amaranthus hybridus (0.98±0.02) at UEF. The concentrations of Pb in Celosia argentea at UEF 5 m from the expressway and Cd concentration in Amaranthus hybridus at 10 m from expressway were above the WHO/FAO permissible levels in vegetables. Level of heavy metal residue observed in soil and vegetables under this study were mostly influenced by the location of the farm-environment and not mainly the vegetable type.  The relative concentrations of Pb and Cd in all the three leafy vegetables raise some serious environmental concerns and need to be monitored regularly to prevent consumption of contaminated leafy vegetables. Farmers are encouraged to cultivate in fields far away from expressway.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88126449","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 primary data was collected through the questionnaire which was validated and tested using confirmatory factor analysis. The second-generation statistical analysis using Structural Equation Modelling (SEM) was adopted which undertakes both regression and factor analysis simultaneously using Partial Least Square Method. The results have shown that there is a significant influence of environmental factors on material-based factors, community-based factors, emotion-based factors, and health-based factors. Further, the community-based factor had significant influence on mental health, emotion-based factor has significant influence on social health, and health-based factor had significant influence on spiritual health. The environmental factors had significant influence on mental, social, and spiritual health. Surprisingly, the environmental factors and material-based factors had no significant influence on physical health. The implications of the study are in the form of suggestions to the managers of tourism industry and the strategic planners of FIFA 2022 in Qatar. Application of scenario planning tools may be required to make an estimate of the material-based factors.

Many international borders were blocked, and individuals were confined to their homes, restricting mobility and changing social habits. The lockdowns introduced economic, physical, and social pastimes to a halt. However, as an advantage, the world had a good effect on air quality, the environment, and greenhouse gases (GHGs), in particular CO2 emissions. When compared to the mean 2019 levels, daily worldwide CO2 emissions had fallen by –17 % (–11 to –25 % for 1) by early April 2020, with changes in surface transportation accounting for little under half of the decline. The total global CO2 reduction from January to April 2020 was predicted to be more than 1749 Mt CO2 (a 14.3 % decline), with the transportation sector contributing the most (58%) followed by coal power generation (29%), and industry (10%). As a result, transportation was identified as the primary source of more than half of the emissions reduction during the epidemic. As of August 23, 2021, 193 countries produced 8.4 million tons of pandemic-related plastic waste, with 25.9 thousand tons dumped into the ocean, accounting for 1.5 percent of total riverine plastic discharge globally. As a result of China and India's record-breaking confirmed cases, MMPW generation and discharge are projected to be more skewed toward Asia. The study found that hospital trash accounts for 73% of global discharge and that Asia accounts for 72% of global discharge, indicating the need for better medical waste management in emerging countries. This review highlights the brief lessening in GHG outflows and expanded request for single-use plastics, including the weight of an as of now out-of-control worldwide plastic squander emergency caused by the COVID-19 widespread. This review also will be helpful for people to understand the COVID-19 impact on climate change point of view. There is advantage and disadvantage brought by this pandemic and it's the best time to change the new normal of globalization. Global policies makers should consider the acute need to change the policies for a circular economy with the best environment sustainable, both during the pandemic and, more significantly, thereafter. The authors of the reference articles on the COVID-19 pandemic hope their findings will aid attempts to better understand the disease's relationship to climate change. If lessons from both global crises are learned, the world may be better prepared to deal with global climate change, which has local consequences.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"12 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82615604","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}

Floods cause serious damage to lives and properties, disrupt economic activities, and, in turn, threaten the sustainable development of human settlements. In Nigeria, flooding has become a recurring phenomenon, sometimes with devastating effects. This study was aimed at assessing the socio-economic, infrastructural, and environmental impacts of floods in Makurdi Local Government Area (LGA). A non-probability sampling technique involving the use of a well-structured questionnaire was adopted in obtaining the required information. Purposive random sampling was used to select four hundred (400) flood victims from the nine (9) local wards bordering the Benue River. Analysis was done using Microsoft Excel and the findings were presented in tables and charts using percentages. The result showed that floods have a huge impact on the community, with greater damage 44% recorded on socio-economic activities (farming, marketing, and administration), followed by a 32% impact on infrastructural facilities (roads, hospitals, and schools), and a relatively lower impact 24% recorded on environmental variables (water, land, and vegetation). An Analysis of Variance (ANOVA) test conducted on these revealed that there is a significant variation in the impact created by floods on the study variables. Flood mitigation and preparedness plans were found to be the leading challenges to long-term flood disaster management in the area. The paper calls for collaborative efforts from residents, flood disaster management agencies, or stakeholders to reduce the impact and improve decisions towards ameliorating the menace of floods in the area. The evidence in this paper seeks to promote actions toward combating flooding and improving flood disaster management in Nigeria.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78210375","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}
