Equally, from the result and analysis obtained on remediation of lead pollutant, Urena lobata has remediation capacity of 0.11 mg/kg with percentage absorbance of 8.53 %. Also, Urena lobata has absorbance and remediation capacity of chromium pollutant with the mean tissue concentration level of 0.26 mg/kg. The absorption rate by the test plant measured were spent engine oil concentration level dependent. Finally, the results showed that the studied plant (Urena lobata) screened for total metal concentration showed value of bio-concentration factor (BCF) < 1 for all heavy metal pollutants, and also high value of translocation factor (TF) > 1 in the following order; Pb (2.000) > As (1.667) > Cr (1.567) > Cd (1.500) mg/kg and as a consequence Urena lobata plant was efficient in translocation of metal pollutants from roots to shoots. \u0000Unique contribution to theory, practice and policy: Urena lobata can then be considered as potential candidates for phytoextraction and phytoremediation of soils contaminated with Cd, Pb, As and Cr. Facility owners and industrialists should adopt and invest on the use of phytoremediation technologies in the remediation of polluted sites with spent engine oil as the technology can remediate more than one pollutant at a time and environmentally friendly. \u0000 ","PeriodicalId":228652,"journal":{"name":"American Journal of Environment Studies","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123285589","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}

A dugong is a herbivorous marine mammal of the tropical and subtropical Indo-West Pacific and the Indian Ocean. Globally, IUCN classified the Dugong as rare; Kenya has done the same under the Wildlife Conservation and Management Act 2013, thus making Dugongs a conservation priority. The study's main objective was to assess dugongs' distribution and status for conservation in Kenya since the 1960s. \u0000Methodology: The study employed a concurrent triangulation design to corroborate findings from three methods. The study used a literature review, semi-structured questionnaires, guided interviews, and focus group discussions with respondents on obtaining socio-economic data. Data was collected in fishing villages with documented and or anecdotal records of the availability of dugongs. Experiences 378 fishers were reached for the study. The study aggregated the number of dugongs sited by decades from the six sampled study sites and presented the data on a line graph. Further, the study computed the rate of change in dugongs from one decade to the next. \u0000Findings: More than 100 dugongs occurred in the Kenyan waters in the 1960s; their population has declined considerably since then. The dugong habitat and feeding area have also shrunk over the same period, further aggravating the situation. There were more than thirty known dugong feeding areas in the study areas; only 10 of them are still known to host dugongs. An estimated 20 dugongs are known to be present in the Kenyan marine waters in the current times. \u0000Unique contribution to theory, practice and policy: This study confirmed the presence of dugongs in Kenya. Further, the dugong numbers are very small, thus showing an urgent need for their conservation. Dugongs are found in Kiunga and Kisite Marine Protected Areas (MPAs) and their immediate surroundings; this amplifies the conservation value of the MPAs.","PeriodicalId":228652,"journal":{"name":"American Journal of Environment Studies","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128209771","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}

With the trajectory analysis known, better contingency planning can be done to protect sensitive areas and the beach activating oil spill response. \u0000Methodology: systematic review past articles on oil spill trajectory analysis from peer was done. This article shows how the surface currents, waves and wind direction affects oil slick movement. The used of GNOME for oil slick modelling as well as the ADIOS for better analysis including the oil dispersed with the estimated budget to clean up the spill provides a better tool for spill trajectory analysis. \u0000Findings: There are two factors that affects the accuracy of oil slick trajectory analysis. The inability to obtain or measure wind and current speeds at the time of the spill and the rotation of the earth thus deflecting the spill either to the northern or southern hemisphere. \u0000Recommendations: Crude oil does not degrade easily and can remain in the environment for decades. Oil production companies needs to put in place a rapid clean up response group with frequent drill exercise. This can help to contain the spilled oil in a timely manner to avoid spreading and further contamination of the sea and other sensitive area. Focus should be on their operating equipment, processes put in place for maintenance strategies and trained qualified personnel to operate their facility.","PeriodicalId":228652,"journal":{"name":"American Journal of Environment Studies","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123112164","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}

Environmental Education is a vital tool to reduce or stop environmental degradation. Several of the environmental problems presently faced by humankind are directly or indirectly caused by misunderstanding of the society about Environmental Education. To address river catchment degradation, this study is in line with priority area 5 of the Global Action Programme (GAP) on Environmental Education and Sustainable Development which emphasises the need for researchers to accelerate sustainable solutions to existing social problems at local level through educational intervention strategies. \u0000Purpose: This study explored the management of river catchment through Environmental Education in Chongwe river catchment. Prior studies on the Chongwe river catchment lacked education approach in addressing the environmental degradation in the catchment. The objective of this study was: to assess the nature of Environmental Education programme taking place if any. \u0000Methodology: This study was guided by critical realism view on research .The study used case study design within the stream of qualitative approach. Targeted population included selected ten (10) local people, ten (10) small scale farmers, two (2) traditional leaders and two (2) experts. Participants were sampled through homogenous purposive sampling while experts were sampled using expert purpose purposive sampling. Data collection instruments included interview schedule, focus group discussion guide and participant observation guide. Data was analyzed though thematic analysis. Data validation was through triangulation method that is through mirror data triangulation techniques. \u0000Findings: From the study findings, the environmental degradation issues in Chongwe river catchment were confirmed and it was found that Environmental Education was being offered in the area but it was not adequate to address the degradation because the Environmental Education offered lacked education approach. This resulted in proposing an Environmental Education programme to address the bad activities in the catchment. \u0000Recommendations: Based on the findings, the study recommended that, there should be formation of an Environmental Forum from the local level incorporating the private sectors, creation of an empowerment scheme like bee-keeping and promotion of best practices in the catchment.","PeriodicalId":228652,"journal":{"name":"American Journal of Environment Studies","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121898426","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}

To that end, the international community has adopted several devices that are mainly anchored on law, ethics and religious doctrines to address the challenges. This paper looks at the relevance of religion towards environmental conservatism. In that regard, the main objective of the study was to ascertain how Traditional African Religious practices, in particular totemism and deity worship, do enhance the sustainable utilization of natural resources and the preservation of ecosystems. \u0000Methodology: This study which was guided by qualitative methods using in-depth interviews, focus group discussions and participant-observations; purposively selected 45 participants based on their knowledge on the subject area across three ethnic groups in Ghana. \u0000Findings: Findings showed that even though practices of totemism and deity worship by African Traditional Regions (ATRs) have aided environmental protection throughout the centuries, it is only coincidental as reasons behind the practices are spiritual and not born out of environmental consciousness or pragmatism. And that, practices of totemsim and deity worship are widely spread in Ghana and observed by all clans in the country. \u0000Recommendations: For effective environmental protectionism, it is recommended amongst other things that in addressing current ecological challenges, both modern scientific methods and indigenous traditional modes be synchronized efficiently. Findings in this article call for the festering of ideas amongst religious environmentalists, environmental institutions, governments and policy makers, towards the efficient management of environmental resources in the given circumstances.","PeriodicalId":228652,"journal":{"name":"American Journal of Environment Studies","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130256068","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 data was then compared with the World Health Organization standard.\u0000Findings: Temporal analyses revealed that all the water samples collected at three different times across the five different sampling points exhibited low variation in their quality, except Cd in sample 1, pH in sample 3, Cd and Cn in control sample 1 and 2 respectively have high variations, while DO and Fe in sample 2, Hg and Fe in control sample 1 and 2 respectively, varied moderately. Biological analysis shows that all the water samples used for the study have feacals, such as Salmonella, Shigella, and E-coli. Spatial analysis result showed that there was high variation between the sampling points though statistically the variation was not significant. Statistically, there was significance difference in pollution level between the dumpsite and the control samples at α=0.05. About 40% of the analysed parameters were above the WHO standard, and 46.7% is within the limit, while 13.3% their permissible limits were not mentioned.\u0000Recommendation: It was therefore recommended that the water be treated before use and the public should be sensitized on the need to always purify their water before consumption.

They were kept for eight weeks retention period. Separate fractions of the undigested and digested treatments were subjected to standard assay procedures to determine their C, N, heavy contents, chemical oxygen demand (COD). The average weekly temperature and the pH before and after digestion of the media were measured. Findings: The cumulative biogas yield was in the order of treatment C (2961.0ml) >D(2241.7ml) > E(2197.9ml) > A(2079.0ml) > B(2031.1ml), based on the following mixing ratios  1:1>3:1>0:1>1:0>1:3. The gas production was affected by weekly temperature variation, which peaked at the mesophilic range (40.5±0.3 ̶ 44.1±0.3OC). The resultant pH of the digestates was in the order of 1:3 > 3:1 > 1:1 > 0:1 > 1:0.
