The growing need for sustainable and clean energy solutions has elevated photovoltaic (PV) systems to the forefront of competitive options. In order to evaluate the performance and viability of single-stage and dual-stage single-phase PV voltage source inverter systems within the context of renewable energy, this study undertakes a thorough comparative analysis. MATLAB Simulink has been used to run the simulations, and the results produced show that the selected configurations are robust and closely match theoretical expectations. The study explores the subtle distinctions, benefits, and drawbacks that come with single- and dual-stage systems. By extensively evaluating the consequences on system stability, grid synchronisation, and power quality, useful insights emerge. The simplicity and efficiency of the single-stage system are demonstrated by the direct connectivity between the PV MPPT output and the inverter. In contrast, the dual-stage system addresses the issue of low PV output voltage by incorporating a boost converter with an MPPT algorithm, albeit at the expense of more parts and complexity. The research described here adds a great deal to the current discussion on PV system optimization. The study notably clarifies methods for improving dependability and efficiency in applications involving renewable energy. With the increasing worldwide trend towards sustainable energy, it is critical to comprehend the subtle dynamics of various PV setups. In addition to offering a comprehensive grasp of the complexities involved in single- and dual-stage single-phase PV voltage source inverter systems, this research paves the way for future developments in the planning and execution of effective renewable energy solutions especially for Asian nations that still rely on coal-based power plants. Increased contribution of solar based electricity generation will lead to a significant drop in pollution contributed by the ash and gases released by thermal power plants that employ fossil fuels. The ultimate goal of this study is to provide information to stakeholders in the renewable energy industry so that they may make more informed decisions and create PV systems that are both sustainable for the environment and efficient for the utility.

This study explores the intricate interplay between global warming, climate change, the COVID-19 pandemic, air pollution, and climate change mitigation. Drawing on lessons learned from the pandemic, we delve into the complex web of environmental challenges and policy responses. The COVID-19 crisis has highlighted the importance of early and determined action, broad public support, equitable policies, global cooperation, and transparent decision-making. While short-term emissions reductions have been observed, addressing climate change requires sustained, transformative change on a global scale. Our analysis underscores the urgency of applying the pandemic’s insights to combat climate change, recognising the interconnectedness of environmental, economic, and public health challenges.

Water quality is an important criterion for meeting water demand and supply. Ensuring freshwater quality that meets human and ecological needs is therefore an important aspect of integrated environmental management and sustainable development. The objective of this study is to monitor and evaluate the quality of the water distributed to the municipality of Sendjas from the Sidi Yakoub dam to the consumer using the index of water quality which includes 10 parameters. (PH, TDS, nitrate, sulphate, bicarbonate, chloride, calcium, potassium, sodium and magnesium). Physico-chemical analyses were carried out on samples taken from the Sidi Yakoub dam, a reservoir which distributes water to the municipality of Sendjas called reservoir 500, and a sample from the house of one consumer directly from the tap. The results of the analyses obtained during our work show that there is a slight difference in the latter, but the quality of the physico-chemical water remains good and consumable at the level of two stations (Sidi Yakoub Dam, Reservoir 500) and Bad quality of the station which represents the municipality of Sendjas, the latter is due to the high content of chloride and the degradation of distribution networks.

The power of the hydrological cycle is enormous, sometimes devastating, but when it is utilised wisely, its negative impacts on humankind can be mitigated. Catastrophic floods and droughts are boosted by the world climate change. Hence, water management programs came into effect. On the other hand, energy production plays a major role in the country’s economic development. So, studies have come up with many ideas to ameliorate disasters especially floods through building mini, small, and large hydro-power plants against the rivers. This study presents a feasibility analysis of flood management and energy production in the Madupetty River, Kerala, India. Even though there are other dams in the Madupetty River, Mudirappuzha basin, the old Headwork built for a hydroelectric project, needs capacity augmentation. This study looks at ways to optimise the Maduppetty River’s water distribution system by building a dam-toe powerhouse where flood water can be stored and utilised when needed. Detailed analysis and design of the hydro-power station is presented. Rainfall runoff equations are used to assess the inflow for power potential studies. During flooding, the projected dam can hold 20.42 MCM of water. From this study, the dam toe powerhouse and cascade powerhouses will create 7.12 Mu and 90 Mu.

The effects of anthropogenic emissions of nitrous oxide (N2O), carbon dioxide (CO2), methane (CH4), and halocarbons on stratospheric ozone (O3) over the twentieth and twenty-first centuries are divided using a chemical model of the stratosphere. As halocarbon levels revert to pre-industrial levels, N2O and CO2 will likely play the primary roles in the evolution of ozone in the future. It is unable to distinguish clearly between these gases’ effects on ozone due to nonlinear interactions between them. The work was conducted using the monthly and annual data of the gases in the stratospheric layer to determine the overlap between N2O and O3 for the Iraq station and for the period (2003-2016). The strength of the association between gases was determined using the Spearman rho test (rs). It was found that there is a very high positive relationship between the N2O and O3 in Nasriyah station, which is 0.807 which indicates a strong association. This is because meteorological conditions, climatic fluctuations, and atmospheric location all affect correlation. The ozone layer is destroyed by nitrous oxide at high concentrations through the stratosphere layer and the tropospheric layer, the concentration of ozone increases with an increase in the concentration of nitrogen dioxide.

The transformation of monsoon rainfall patterns in India, largely attributed to climate change, is leading to more frequent and severe floods. These escalating challenges underscore the imperative of prioritising adaptive measures, given the intrinsic link between humans and climate change. This research conducted in Majuli Island, a highly vulnerable region in India’s northeast, aims to understand current adaptive strategies and assess potential risks from impending physical exposures. Empirical evidence was collected using purposive sampling in two flood-prone villages. The objective was to revisit the Mishing community’s experiences with annual flooding and climate challenges. Thematic analysis interpreted the qualitative findings. Implications for community-based adaptation and sustainable practices are discussed for future flood and climate challenges. The study emphasises strengthening ecosystem-based adaptation through multi-sectoral networking in Majuli Island, Northeast India.

UN World Water Development Report 2022 ‘Groundwater: making invisible visible’ - has pointed out that the major source of freshwater is groundwater. Groundwater conservation and replenishment have taken the forefront in view of the water crisis faced by the world. Groundwater management is action-oriented, focusing on practical implementation activities and day-to-day operations. It occurs more often at the micro- and meso-level. The urban area has the privileges of an established public water supply system, the suburbs and periurban areas are almost entirely groundwater dependent. The surface water runoff is mostly wasted and drained into the nalla/ river in these areas. Peri Urban zone of Nashik includes 177 institutional campuses (schools and colleges). These campuses can be developed as role models and act as leaders for water conservation methods and groundwater recharge for the neighbouring rural zone. This research is based on a methodology that involves three-pronged approaches, which consist of a) Identifying the potential of educational campuses in the peri-urban zone, b) educating the school students about the water and its conservation techniques as primary stakeholders of the future and c) creating platform at the school level to interact with the villagers in the vicinity to create the actual impact of the replenishment. This approach ensures active participation of the stakeholders (campus management, admin, student community) in periurban areas for groundwater recharge. Thus sensitising the student community as the primary stakeholder ensures the bottoms up approach for sustainable urban development. This transdisciplinary approach of engaging the students with the community drives two fold benefits - one, of committed habit formation in them & second, of becoming a leader & a resource person for future green development of the area The discussions on groundwater conservation in this paper point out to the need to coin principle of “Owner Replenishes”- for water conservation on the lines of “Polluter Pays”.

The Ain Zada dam is experiencing a deficit in recent years due to scanty precipitation and reduced water flow, resulting in the dam’s water reserve dropping to 8.3%. Our study’s primary objective is to assess the quality of both untreated (raw) and treated water from the Ain Zada dam by conducting physico-chemical analyses on both samples. Based on the findings, the physico-chemical quality of the treated water is deemed satisfactory, as all samples adhere to Algerian standards. The treated water exhibits an organic matter concentration of 4.94 mg/l, which is the chief contributor to the unfavourable odour and taste of the dam water. To address this, enhancements will be made to the Ain Zada dam treatment station this year through the adoption of a novel ozone disinfection method (ozonation). The Water Quality Index (WQI) for treated water from the Ain Zada dam indicates a favourable suitability for drinking water production from February to May 2022. Two quality categories are discernible for each scenario based on the obtained WQI values: excellent and good for treated water, and excellent and poor for raw water. Water quality diminishes notably in April, where the treated water quality index rises (25 < WQI . 50), while the raw water’s quality classifies as poor (WQI > 50). The decline in water quality during this month can be attributed to stream variations, agricultural activities, and urban wastewater discharges. Consequently, it is imperative to prioritise the reduction of these pollution sources to safeguard water resources and enhance water quality within the watershed.
近年来，由于降水稀少，水流量减少，艾因扎达大坝的水量出现赤字，导致大坝的蓄水量下降到 8.3%。我们研究的主要目的是通过对艾因扎达大坝未经处理（原水）和处理过的水样进行物理化学分析，评估这两种水的水质。根据分析结果，处理过的水的物理化学质量令人满意，因为所有样本都符合阿尔及利亚标准。经过处理的水的有机物浓度为 4.94 毫克/升，这是造成大坝水气味和味道不佳的主要原因。为解决这一问题，今年将通过采用新型臭氧消毒方法（臭氧消毒）来改进 Ain Zada 大坝处理站。艾因扎达大坝处理过的水的水质指数（WQI）表明，2022 年 2 月至 5 月期间的饮用水生产非常适宜。根据获得的水质指数值，每种方案可分为两个水质类别：处理后的水质为优和良，原水水质为优和差。四月份的水质明显下降，处理水的水质指数上升（25 < WQI .该月水质下降的原因可能是溪流变化、农业活动和城市污水排放。因此，必须优先减少这些污染源，以保护水资源和提高流域内的水质。

Waste scavengers face occupational hazards from exposure to toxic landfill emissions, putting them at risk for respiratory illnesses. This study aimed to assess the impacts of landfill gases on lung function in scavengers. Spirometry was used to evaluate lung function in scavengers at 5 dumpsites in Baghdad compared to non-exposed controls. The results showed that winter measurements in the internal measuring point for carbon dioxide indicated that the highest concentration was 454.89 ppm in the Adhamiya landfill and the lowest concentration was 397.65 ppm in the Baghdad Aljadeeda landfill. Lung disease cases were recorded and correlated to landfill sites, work duration, and seasons. The results of the lung efficiency examination showed a clear decrease in spirometry parameters at high-pollution landfill sites with varying concentrations of particulates and gases compared to the control group—more airway restriction cases correlated with increased years of scavenger exposure and higher pollutant levels. As noted, severe respiratory symptoms increased in the summer season likely due to the influence of climatic factors.

The results showed that winter measurements in the internal measuring point for carbon dioxide indicated that the highest concentration was 454.89 ppm in the Adhamiya landfill and the lowest concentration was 397.65 ppm in the Baghdad Aljadeeda landfill. Lung disease cases were recorded and correlated to landfill sites, work duration, and seasons. The results of the lung efficiency examination showed a clear decrease in spirometry parameters at high-pollution landfill sites with varying concentrations of particulates and gases compared to the control group—more airway restriction cases correlated with increased years of scavenger exposure and higher pollutant levels. As noted, severe respiratory symptoms increased in the summer season likely due to the influence of climatic factors.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140370282","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}
