A Study of Urban Noise Pollution in Jalalabad City of Nangarhar Province, Afghanistan

This study examines the pervasive issue of global noise pollution and its implications for human health, specifically concentrating on 16 hightraffic locations within Jalalabad, Afghanistan, utilizing the Sound Meter application for data acquisition. The conspicuous absence of antecedent research accentuates the significance of this inquiry. The analysis identified traffic, loudspeaker systems, and human activities as primary contributors to ambient noise. Over a meticulously documented 32-day period in March and April of 2023, notable noise peaks were observed, notably at Talashy Square, registering 73.5 dB at 3:00 PM, and at Malang Jan Watt, reaching 87.5 dB at noon. Urgent intervention is imperative to ameliorate these conditions for the well-being of the city’s residents, urging policymakers to implement efficacious noise abatement strategies. This research offers pivotal real-time noise data for Jalalabad and suggests mitigation measures, stressing the necessity for further scrutiny to assess strategy effectiveness, aiming for a harmonious urban environment.

Community-Based Adaptation to Climate Change in Water Sector: Engaging Local Knowledge and Practices in Achin District, Nangarhar, Afghanistan.

Climate change involves persistent changes in global temperatures and weather patterns, predominantly attributed to human activities that release greenhouse gases into the atmosphere. This study specifically focused on community-based adaptation in the water sector, exploring local knowledge and practices within Achin district. Through this investigation, we gathered detailed insights into the effects of climate change within Achin district and assessed the knowledge and local practices adopted by its residents. Primary water sources in the area, such as protected wells, springs, and boreholes, are highly relied upon by residents who generally express satisfaction with their reliability and quality. However, there is a prevalent lack of awareness regarding Household Water Treatment and Safe Storage (HWTS) among most residents. Climate change effects within Achin district include drought, groundwater depletion, surface water decreasing for irrigation, and shifting precipitation patterns. Despite these challenges, the residents lack knowledge about community-based adaptation. Local strategies employed within the district encompass dams, plantation initiatives, mobilization efforts, awareness campaigns on water usage, underground water recharge, and irrigation projects. Additionally, improved irrigation practices and effective conservation methods are identified as vital adaptation strategies. This study thoroughly assesses the impact of climate change on the water sector in Achin district, emphasizing local adaptation strategies. Through field visits, interviews with the residents of Achin, and the implementation of a Google Form survey from environmental and WASH specialists, we meticulously cataloged the effects of climate change and illuminated the indigenous responses adopted by the district's residents.

The Impacts of Variation in Temperature and Precipitation on Surface Water: A Case Study of Nangarhar, Afghanistan.

Abstract — The water levels of surface water in Nangarhar are a direct and major reflection of the changes in precipitation and temperature. However, the changes in temperatures also influence evapotranspiration rates, which in turn affect water availability. This work is essentially a detailed study of the effects of the changes in temperature and precipitation on surface water at the three sites of Nangarhar (Behsood Bridge, Kama Bridge, and Sultanpor) during the 2009-2020 period. The temperature and precipitation changes at all three sites have led to changes in surface water levels, as evidenced by the data. In particular, the temperature at Behsood Bridge increased by 0.84°C between 2009 and 2020, while at Kama Bridge, it decreased by 0.96°C. From 2010 to 2020, the temperature in Sultanpor also went up by 1.08°C. Besides that, the research showed that there was a yearly increase in precipitation at the locations with the yearly increases being 7.00mm at Behsood Bridge, 16.79mm at Kama Bridge, and 17.27mm at Sultanpor respectively. One of the effects of increase in precipitation and temperatures may be the direct and indirect impacts on the surface water levels. The surface water gets replenished with increased precipitation but is depleted when there is increased heat. During the period under study, the volume of water in the rivers increased by 6,765.78m3/sec at Behsood Bridge, 6,794.84m3/sec at Kama Bridge, and 141.82m3/sec at Sultanpor. This paper is a commitment to the analysis of the changes in precipitation, temperatures, and surface water quantity in Nangarhar, Afghanistan and aims to provide substantial benefits for local water resource management and sustainability.

Utilization and effects of various particle sizes of waste glass powder as partial replacement of cement in concrete

This paper outlines the study undertaken regarding the usage and impacts of different particle sizes of Waste Glass Powder (WGP) when used as a partial replacement for cement in concrete. Through utilization WGP as a cement substitute, the mechanical and physical attributes, compressive strength and workability of concrete were assessed. The glass has been sieved from #200 sieve which has size of 74 μm and also sieved from #325 sieve which has size of 44 μm for a partial substitute of cement. To compare the WGP-replaced concrete's properties to reference specimens with no replacement at all, WGP was used to substitute 20% of the Portland cement in the concrete. The control samples were created following the IS-10262-2009 standard to reflect a goal of 30 Mpa, and cylindrical samples were fabricated, subjected to curing, and assessed for workability and compressive strength at intervals of 7, 14, 21, and 28 days after its casting. In conclusion, when the WGP particles are smaller, concrete becomes more workable and has a higher compressive strength then concrete with bigger particle sizes of WGP and control samples with no replacement. The findings of this study led to the conclusion that WGP's cementitious properties are acquired by its finer particles.
