A significant portion of waste thrown into landfills is organic kitchen waste that decomposes to produce greenhouse gases responsible for climate change and environmental risks. \u0000This observation is that of our results, which point out that poor management of food waste, the landfills which receive it are uncontrolled and thus leaving access to human persons due to the proximity to the residential houses, as well as to insects and animals. Incineration is the main method used to dispose of waste, with very few initiatives for recycling or composting of waste, thus leaving their degradation or incineration in the open air with all the consequences on the carbon footprint and the climate. \u0000Initiatives for the good use of waste, in particular: recycling, composting, etc., must be encouraged for the good management of waste and landfill sites in order to preserve our environment from greenhouse gases.

This comprehensive review paper synthesizes multidisciplinary studies to explore the contribution of mangroves in reducing the risk of catastrophes such as storm surges, tsunamis, hurricanes, and coastal erosion. By analysing the complex relationships between mangroves and natural disasters, we delve into factors such as species composition, forest structure, hydrological regimes, and coastal geomorphology. Additionally, we investigate the socioeconomic implications of mangrove conservation and restoration efforts, highlighting their potential to enhance resilience and sustainable development in coastal communities. The paper presents a detailed examination of wave characteristics, types, and attenuation mechanisms, focusing on how mangrove features such as prop roots, knee roots, and pneumatophores influence wave dissipation. We discuss various numerical and statistical models used to predict wave attenuation through mangroves, providing insights into their strengths and limitations. Furthermore, we explore global and India-specific mangrove cover status, important species, and conservation measures, including legal frameworks and initiatives by governmental and non-governmental organizations. Finally, the review underscores the urgency of conserving and restoring mangrove ecosystems to safeguard both human well-being and ecological integrity in the face of escalating climate-related threats. It advocates for evidence-based decision-making and policy development in disaster risk management and climate adaptation, emphasizing the pivotal role of mangroves as natural shields against natural calamities. Overall, this paper contributes to the understanding of mangrove-mediated hazard reduction and provides guidance for maximizing the resilience of coastal communities in an increasingly volatile world.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140996591","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 aim is to evaluate the physicochemical parameters and heavy metals of the water of Lake Chapala to evaluate its water quality, during the period 2010-2023, and to estimate the ecological and health risks. The results will provide valuable information on water quality management and protection of human health. The design is an ecological study, using water quality, pollution risk, ecological and health risk indices. The place and duration of the study is the Lake Chapala during the period 2010-2023. The methodology consisted of obtaining the quality data of the Water Lake Chapala through the State Water Commission, the National Water Commission and studies conducted by the University of Guadalajara. The analyses were conducted on a monthly basis from 2010 to 2023. Subsequently, the CWQI, WQI, NP, HPI, HEI, DC, PERI, HQ, HI, THI, CR and TCR indices were calculated to determine water quality and ecological and health risks. The results showed que the distribution of parameter concentration showed great spatial variation, but not temporal; the TDS, Turbidity, pH, Al, As, Cr, Cu, Mn, Pb and Zn with percentages above the CCME standard, but most of them within the NOM-001-SEMARNAT-2021. The heavy metals Al, As, Cr, Pb and Zn have concentration percentages of more than 100% with respect to the international standard. The remaining 14 parameters are within both national and international standards. Pearson's correlation analysis showed that none of the trace elements have positive correlations with each other. Water quality according to the WQI of 178 was categorized as poor quality, while for the CWQI almost all uses except grazing, water quality is poor (20-35). According to the NP index (3.8 to 670), the concentrations of heavy metals showed high levels of contamination. The HPI index (88.6) showed moderate to high levels of heavy metal contamination. The HEI index showed <10 levels, indicating low contamination. The DC had a value of 0.2-18.2, classified as a high degree of contamination. The PERI index showed that the ecological risk from heavy metals is high. Non-carcinogenic risk indices indicate that lake water is not suitable for drinking, and poses a high health risk via ingestion, while dermal contact does not pose a health risk to residential and recreational recipients. The carcinogenic risk index is negligible to acceptable. The conclusion is according to the water quality, ecological and health risk indices, the water quality of Lake Chapala is poor, with a high degree of contamination and represents ecological and health risks (non-carcinogenic). It is recommended that the use of lake water does not include its ingestion to avoid health problems, and it is important to take measures to sanitize the lake to avoid ec","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment &amp; Ecology","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141013497","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 objectives include the identification and selection of suitable reservoirs, correlating the reservoirs across the field, generating synthetic seismograms and seismic-to-well ties, performing structural interpretation of faults and horizons to generate time and depth structure map, identifying potential prospects and volumetric analysis to estimate the volume of hydrocarbon in place. The adopted methodology comprises structural, petrophysical and volumetric analysis facilitated by Petrel and Techlog software suites. Well log were utilized to identify distinctive features and cross-well stratigraphic correlation which revealed complex variations, indicating a potential thickening trend in the Agbada sequence towards the southwest. Faults and horizons were mapped to establish the structural framework, unveiling a faulted rollover anticline influenced by lateral fault block movements, contributing to a complex structural style. Detailed analysis of seismic responses, synthetic seismograms, and petrophysical parameters from the well log led to the identifying and correlating of eight prospective reservoir intervals (Reservoir A to H). Average petrophysical parameters, including thickness, porosity, Not-to-Gross ratio, volume of shale, and water saturation were derived from the petrophysical analysis, confirming the eight reservoirs exhibit good petrophysical properties, indicating their potential as promising prospects. The reservoirs exhibit varying qualities, with a southward decline in reservoir quality and indications of gas-water contacts in reservoir A with a similar trend across the other reservoir units.
