The Impact of Solid Waste Generation, Storage and Separation Practices among Households on the Environment in Freetown

引用

Journal of Geoscience and Environment Protection 2024年第8期12卷 219-238页

作者： abdul Malik Bangura Patrick Fayia Kanty College of Environmental Science and Engineering Tongji University Shanghai China

As urbanization and population growth continue to increase in Freetown, due to changes in economic, social, environmental, political, and demographic factors, the municipal solid waste (MSW) generation also continues to increase, making its management difficult for the municipal authority. Efficient separation and storage of solid waste at the source of generation can boost resource and energy recovery from MSW. This study examines the municipal solid waste management (MSWM) process, focusing on generation, storage and separation practices among households and their impact on the environment in Freetown. It emphasizes the inclusion of MSWM programs in primary schools to raise public awareness, the implementation of effective waste management practices, and the enforcement of related policies to enhance the MSWM sector, contributing to sustainable MSWM in Freetown. By utilizing both qualitative and quantitative methods, 393 structured questionnaires were administered across three selected sections to collect data on household solid waste storage and separation practices. The analysis employed descriptive statistics, using Origin-Pro9 and MS Excel. The findings show that with a population of 1.53 million people in Freetown, the per capita solid waste generation is 0.58 kg per day. The findings also show that 97% of the households have storage facilities as a result of the increase in awareness and education about the proper storage of solid waste. However, 96% of respondents do not practice separation of solid waste at the source of generation, which has become a concern among researchers in Sierra Leone. Additionally, 88% of respondents are unaware of ISWM principles, with only 12% aware, most of whom have received some education on proper solid waste management. The study recommends improving MSWM in Freetown to protect public health and the environment.

上海合作组织(SCO)在缓和成员国之间的冲突方面发挥着至关重要的作用,特别是在印度和巴基斯坦之间错综复杂的安全动态方面。这一区域多边外交论坛在思考这一区域历史背景和当代地缘政治复杂性以促进区域和平与稳定方面面临挑战,但也有着发展前景。它是地区和全球政治舞台进程中的一个关键点,除了单纯的经济和科技合作外,还为消除地区三害(即分裂主义、极端主义和恐怖主义)带来了希望。根据巴基斯坦外交政策的观点,巴基斯坦面临着重大障碍,如西方和美国在该地区原有的影响力、该地区的恐怖主义危机和克什米尔问题。为了克服这些问题,巴基斯坦作为成员国认真、积极参与上海合作组织,寻求并促使上合组织成员国通过这一多边外交论坛解决地区安全问题,如阿富汗问题、地区安全危机,尤其是巴基斯坦与印度之间的顽固困境。2017年6月在哈萨克斯坦阿斯塔纳举行的上合组织第17次会议期间,巴基斯坦和印度被接纳为正式成员。自2001年6月15日成立以来,这是该组织在地理、经济和安全方面重大发展。目前上合组织将巴基斯坦和印度视为南亚地区最强大的两个国家并给与了它们双倍的关注。上合组织的长期扩张计划取得了成功,这一增长将在科技、经济、安全等领域取得发展势头,这表明上合组织的内部发展已基本完成。地区主义的产生通常是由地理特征、社会文化背景、经济合作、安全等多种变量和因素共同作用的结果。基于地区主义的特点、地区安全关切以及对当前复杂安全危机和地区问题的集体和平管理,本研究采用安全治理与地区主义的方法,分析以上海合作组织为代表的欧亚地区主义的显著特征。上合组织的地区性质可以从接纳巴基斯坦和印度为成员国的过程以及地区安全问题中观察到。本研究将涉及三个方面,即上海合作组织在解决地区安全相关问题方面的性质和演变;安全治理:上海合作组织应对当代地区安全挑战的方式;以及通过对上海合作组织成员资格的扩大研究来识别地区主义。本研究的重点和主题是通过定性研究方法评估巴基斯坦与上合组织、印度与上合组织、上合组织及其在巴基斯坦和印度之间冲突缓和中的[潜在]作用以及挑战和前景,强调通过这一多边外交平台解决这些问题、促进协作、合作和实现地区和平的重要性。本文探讨了上海合作组织在缓和包括巴基斯坦和印度在内的成员国之间的竞争和争执方面所发挥的作用。为了全面解释上合组织缓和紧张局势的能力,本文仔细研究了该组织以地区主义为基础的政策,以及巴里·布赞(Barry Buzan)和奥利·维夫(Ole Waever)提出的区域安全复合体理论。此外,本研究还采用建构主义的观点来阐明影响上合组织解决印巴冲突机制的意识形态因素。本文共分五章。第一章提供了研究的基本结构。该章以详尽的导言开篇,概述了研究的背景和意义,介绍了研究方法问题,包括研究设计、数据收集技术和扩展分析策略。通过明确提出的研究问题,文章将分析引向特定和有针对性的调查。研究的目的是清晰的阐述,使人对预期结果和结论一目了然。研究的重要意义在于其对当代国际关系研究和实践领域可能做出的贡献。这一章包含理论方法的一部分,其为后续研究中使用的理论框架提供了背景。此外,在缓和冲突、建立信任与合作的框架内,本节批判性地分析了国际关系中的新自由主义和新现实主义范式,对新自由主义和新现实主义的缺点进行了深入研究和透彻分析,提出了详尽的论据,最终对其观点进行了批判性的分析。作为一种替代性的观察角度,建构主义被强调用来阐释其如何通过强调概念、惯例和身份等因素对国际关系的影响,为国家行为提供了更为深入和复杂的解读。这一部分还旨在将区域安全复合体理论(RSCT)与建构主义联系起来。这一探讨试图通过将这些理论框架联系起来,揭示意识形态因素与地区安全动态之间的相互作用。这种细致的分析有助于更透彻地理解构成地缘政治环境的错综复杂的关系,为国际关系研究中更全面、更符合历史的理论框架打开大门。本研究的第二章探讨了上海合作组织的建立和运作,强调了该组织对解决该地区错综复杂的安全问题所做出的贡献。在上海合作组织的框架内,本章探讨了地区主义和地区化的思想,深入探讨了这些因素如何影响该组织的目标和运作。通过仔细研究该组织的历史演变、程序和结构,本章深入探讨了该组织在地区安全中的作用是如何随着时间的推移而变化的。对话还涉及上海合作组织内部信任的维护,探讨了如何培养和维护成员国的信任。此外,本章还探讨了上合组织的早期程序,特别是与建立信任和缓和冲突有关的程序。本章通过案例研究的方式,旨在从更为细致的角度,深入剖析上合组织在处理地区安全问题时所展现的效率。在这一过程中,特别关注了中国与俄罗斯、乌兹别克斯坦和哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦以及乌兹别克斯坦等特定成员国。本论文的第三章对上合组织参与化解巴基斯坦和印度之间的紧张局势进行了细致的研究。第一节探讨了国际关系中冲突的复杂性,区分了冲突升级和冲突降级两种

Microplastic Can Decrease Enzyme Activities and Microbes in Soil

引用

Open Journal of Soil Science 2024年第1期14卷 1-12页

作者： Tazeen Fatima Khan abdul Halim Farhad Sikder Department of Soil Water and Environment University of Dhaka Dhaka Bangladesh Center for Environmental and Geographic Information Services Dhaka Bangladesh

An in vitro study was conducted to investigate the impacts of microplastics on enzyme activities and soil bacteria. The study included four different treatments of microplastics including a control. Different levels of microplastics were applied to the soil ranging from 0% to 5%, to assess the impacts of microplastics on soil enzymes and subsequent soil bacteria. After 30 days of incubation, the soil samples were collected and growth parameters of bacteria were assessed. Activities of β-glucosidase, urease and dehydrogenase enzymes were also determined. Our results showed that the presence of microplastics in the soil significantly reduced bacterial population together with bacterial strains. The activities of β-glucosidase, urease and dehydrogenase enzymes were reduced significantly to approximately 32%, 40% and 50% in microplastics treated soils respectively. Concentration of microplastic has a role to play towards this direction;the higher the concentration of microplastic the greater is the impact on enzymes and soil bacteria. The present study on the microbial soil health vis-à-vis microplastic application indicates that the material can have negative effect on the soil bacterial population of and thus ultimately may jeopardize soil health and crop production.
