Samples of leachate and soil these were analyzed in the laboratory, firstly to achieve the recoverability in Agar Soy Tripticase [AST] and proceeded to their identification by biochemical tests. \u0000Results: Among the chemical products perceived when visiting this socio-environmental context is hydrogen sulfide, which impacts the nervous system at the level of neurobiological vitality. The acute-chronic exposure in the population adjacent to the landfill and its leachates is enough to insist that environmental control of this area be warranted. Among the bacteria detected, 60% were Gram-positive bacilli and 30% were Gram-negative bacilli. Bacteria present in this environment are: Bacillus cereus, Bacillus subtillis, Bacillus sp and Pseudomonas aeuroginosa, P. putida, Klebsiella pneumoniae, Escherichia coli and Enterobacter cloacae. Conversation with people denotes exposure to chemicals-microorganisms and risks to human health. \u0000Conclusion: The presence of microorganisms and virulence profile are aspects to be considered in these bacteria is their virulence profile, and their biotechnological profile when they present an effect as generators of plant growth. For this reason, the study of this type of bacteria is transcendent in the fields of Environmental Sciences and Public Health.","PeriodicalId":502350,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"68 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141651310","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}

{"title":"Assessing the Sustainability of Kilongo Forest Reserve under Community-Based Management in Wangingómbe District, Njombe Region, Tanzania","authors":"Laison S.

Among other things, this management regime has been associated with improving both forest conditions and community livelihoods. Recent studies, however, indicate that forests under community-based forest management (CBFM) are decreasing, subjecting them to degradation and complete land use change. This study, therefore, assesses the sustainability of Kilongo Forest Reserve under CBFM in Wangingómbe District, Njombe Region, Tanzania. Data was collected from 90 heads of Kilongo Sub-Village households in the study village of Masaulwa using probability and non-probability approaches through structured interviews, in-depth interviews, and documentary reviews. The results showed that Kilongo Forest Reserve conditions improved noticeably over the 20-year period under CBFM through increased forest density, tree height, and undergrowth diversity. This was due to the existence of rules and regulations, as well as villagers' involvement in forest management. However, with the exception of the increased harvests of honey, the results demonstrate that the improved forest conditions did not significantly improve the livelihoods of the villagers. This is because the trees were not mature enough to produce timber. On the other hand, the forest reserve faced the challenge of animals passing through or grazing within the forest, as well as illegal harvesting of forest resources. It was also noted that the presence of numerous actors, multiple power centres, a village environmental management committee (VEMC) that was neither accountable to the villagers nor under their control, and the unequal distribution of benefits all compromised the effectiveness of Kilongo Forest Reserve. This study concludes that Kilongo Forest Reserve management under CBFM is not sustainable. Thus, to ensure the sustainability of Kilongo Forest Reserve under CBFM, there should be a complete decentralisation in the governance of the forest reserve, and the villagers should reduce their reliance on wood for energy by enabling them to use alternative sources of energy.","PeriodicalId":502350,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"44 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141654984","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}

Clay deposits in the Ratnapura District are often unearthed during gem mining operations. Unfortunately, excavated deposits are frequently disposed of openly on the ground without undergoing any value-addition process. This practice alters the soil condition of the vicinity, as the clay soil blocks the gravitational flow of rainwater. This environmental impact can be overcome by adding commercial value to these kaolinitic clay deposits. The present study aims to demonstrate the feasibility of extracting alumina from kaolinitic clay found at gem mining sites and to evaluate the potential of the extracted alumina as an adsorbent. Kaolinitic clay samples were collected from a gem mining site in the Ratnapura District. First, kaolin was transformed into metakaolin through calcination, and then alumina was extracted from the metakaolin via acid leaching using HCl as the leaching agent. Aluminum ions were separated from the leaching solution as Al(OH)₃ using NaOH as the precipitant. The precipitated Al(OH)₃ was transformed into alumina by calcination. The adsorption properties of the extracted alumina were evaluated using methylene blue solution as the adsorbate. Kaolin, extracted, and commercial alumina samples were characterized using XRD, XRF, FTIR, and SEM analysis. XRF analysis revealed that kaolin consists of 29.11 % alumina by weight, and the purity of the extracted alumina was 90.03%. The crystalline phase of extracted alumina was identified as the γ phase via XRD analysis. Extracted and commercial alumina exhibited similar trends in the adsorption of methylene blue under varying adsorption parameters. Accordingly, γ-phase alumina with a purity exceeding 90% can be produced from the kaolinitic clay found at the gem mining site under these experimental conditions. The extracted alumina has demonstrated potential for use as an adsorbent, exhibiting compatibility with commercial alumina.","PeriodicalId":502350,"journal":{"name":"Asian Journal of Environment &amp; Ecology","volume":"66 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141337947","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}

Post-bauxite mining reclamation efforts are most times inadequate. As a result, some abandoned pit mines have turned into lakes, now used for recreational activities. This study examines the heavy metal distribution in two locations affected by bauxite mining: the recreational Kara-Kara Blue Lake (BL) and the active Tailing Pond (TP). Using X-ray fluorescence, ten sediment samples from these sites were analysed for metals such as Al, Co, Cd, Cr, Cu, Fe, Mg, Mo, Ni, Pb, Ti, and Zn. Data analysis was conducted using Microsoft Excel, SPSS, and JASP software. The heavy metals in the Tailing Pond demonstrated a decreasing sequence of Fe > Ti > Al > Mn > Ni > Cd > Co > Cr > Zn > Pb > Mo > Cu, while in Blue Lake, the order was Ti > Fe > Mn > Co > Cr > Cd > Ni > Mo > Zn > Pb > Cu > Al. The study employed the Contamination Factor (CF) and Pollution Load Index (PLI) to evaluate pollution levels, revealing higher contaminant levels in the tailings pond than in Blue Lake, with PLI values of 1.06 and 0.83, respectively. Although Blue Lake appears relatively unpolluted and suitable for recreation, both lakes' elevated Ni, Cd, and Cr levels necessitate continuous monitoring to mitigate long-term exposure risks.","PeriodicalId":502350,"journal":{"name":"Asian Journal of Environment &amp; Ecology","volume":"100 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381470","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}

We conducted an in-depth study of previous research, reports, and related literature. Sources were selected based on relevance and credibility to provide a thorough examination of the impacts of climate change on agriculture. \u0000Analysis: The analysis focused on categorizing the direct and indirect effects of climate change on agricultural systems, understanding changes in crop yield, plant physiology and metabolism, and evaluating the effectiveness of various mitigation strategies. \u0000Result Findings: The findings indicate that the greenhouse effect, driven by gases such as CO2, CH4, and H2O, leads to global temperature increases. The concentration of these gases is rising, with the global average temperature expected to increase by 2°C by 2100, causing significant economic losses. While this increase has boosted plant growth and productivity through enhanced photosynthesis, the associated rise in temperature counteracts these benefits. \u0000Therefore, mitigation strategies such as nutrient management, drip and sprinkler irrigation, and sustainable agricultural practices are essential. Natural farming is a sustainable agricultural practice that offers chemical-free, healthy food while promising to increase farmers' income, improve environmental health, restore soil fertility, and reduce greenhouse gas emissions. \u0000Conclusion: Climate change poses a significant threat to global food and nutritional security by altering agricultural productivity and sustainability. Understanding these impacts and developing effective mitigation strategies is crucial. This review provides valuable insights for policymakers, researchers, and practitioners to address these challenges and ensure resilient agricultural systems capable of sustaining future food security.","PeriodicalId":502350,"journal":{"name":"Asian Journal of Environment &amp; Ecology","volume":"38 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384451","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}
