Over the last few decades, the contribution of CO2 emissions to the environment has shown an increasing trend. The greenhouse gases increase the temperature of the environment globally and particularly in Pakistan. History is witness that the activities of humans mostly affect the environment. The goal of this study is to explore the link between variables such as Trade, FDI (Foreign Direct Investment), REC (Renewable Energy Consumption), EPC (Electricity Power Consumption), Economic Growth, Urban Population, and Carbon Emissions inside Pakistan over the time period of 1990 to 2022. The Auto Regressive Distributed Lag (ARDL) technique is utilized for estimation. The result shows that the long-run relationship exists between these variables. The REC, Economic Growth, and FDI significantly affect CO2 emissions, while the remaining variables have insignificant effects on carbon emissions. Moreover, based on the findings of this study recommends that the government adopt strict policies and strategies to overcome climate problems and control pollution.
在过去的几十年里,二氧化碳排放对环境的贡献呈现出增加的趋势。温室气体增加了全球环境的温度,尤其是在巴基斯坦。历史证明,人类活动对环境的影响最大。本研究的目的是探讨1990年至2022年期间巴基斯坦内部贸易、外国直接投资(FDI)、可再生能源消费(REC)、电力消费(EPC)、经济增长、城市人口和碳排放等变量之间的联系。采用自回归分布滞后(ARDL)技术进行估计。结果表明,这些变量之间存在着长期的关系。REC、经济增长和FDI对碳排放影响显著,其余变量对碳排放影响不显著。此外,根据本研究的结果,建议政府采取严格的政策和战略来克服气候问题和控制污染。

Climate change has an impact on human health, and it is generally known that environmental degradation and climate change are related. The utilization of fossil fuels results in more CO2 emissions into the atmosphere, a greenhouse gas that dramatically raises global temperatures. By replacing oxygen in the atmosphere, CO2 emissions have an impact on human health. While CO2 emissions hurt human health, sometimes economic expansion has a favorable impact on public health and vice versa. Using the Autoregressive Distributive Lag model (ARDL) and annual time series data from 1985 to 2020, this study aims to investigate the relationship between CO2 emissions, health spending, and economic growth in Pakistan. The empirical findings of this study demonstrate a substantial long-run and short-run relationship. To use technologies that cause emissions, the government must increase its investment in renewable energy sources and implement carbon taxes.
气候变化对人类健康产生影响,众所周知,环境退化与气候变化是相互关联的。化石燃料的使用导致更多的二氧化碳排放到大气中,这是一种显著提高全球气温的温室气体。二氧化碳排放通过取代大气中的氧气,对人类健康产生影响。虽然二氧化碳排放损害人类健康,但有时经济扩张对公众健康产生有利影响,反之亦然。利用自回归分布滞后模型(ARDL)和1985 - 2020年的年度时间序列数据,本研究旨在探讨巴基斯坦二氧化碳排放、卫生支出和经济增长之间的关系。本研究的实证结果表明,长期和短期之间存在显著的关系。为了使用导致排放的技术,政府必须增加对可再生能源的投资,并实施碳税。

Based on the Environmental Kuznets Curve (EKC) theory, this research seeks to probe the impact of nuclear and renewable energy on carbon emissions in Pakistan. In order to analyze Pakistan's cointegration from 1990 to 2022, this study uses the ARDL technique. The findings provided empirical support for the Environmental Kuznets Curve (EKC) theory and demonstrated that the use of nuclear and renewable energy resources is linked to lower carbon dioxide (CO2) over the long term. Carbon dioxide emissions from burning fossil fuels, which are used for most of the world's energy needs, have been steadily rising in recent years. Policymakers recognize this and are working to reduce reliance on nonrenewable energy sources while increasing nuclear and renewable energy use.
基于环境库兹涅茨曲线(EKC)理论,本研究旨在探讨核能和可再生能源对巴基斯坦碳排放的影响。为了分析1990年至2022年巴基斯坦的协整,本研究使用了ARDL技术。研究结果为环境库兹涅茨曲线(EKC)理论提供了实证支持,并证明了核能和可再生能源的使用与长期降低二氧化碳(CO2)有关。化石燃料是世界上大部分能源需求的来源,近年来,化石燃料燃烧产生的二氧化碳排放量一直在稳步上升。决策者认识到这一点,正在努力减少对不可再生能源的依赖,同时增加核能和可再生能源的使用。

The study explores clean cooking fuel poverty in Bangladeshi households based on the energy ladder hypothesis stating that as income increases, households switch towards cleaner cooking fuels. Data from the Bangladesh Demographic and Household Survey (BDHS) 2017-18 reveals that 20.45% of households use advanced or cleaner cooking fuels, while a majority (79.23%) still rely on primitive or traditional cooking fuels. Electricity is used by a very small percentage (0.57%), while LPG is used by a slightly higher proportion (6.96%). Biogas usage is minimal (0.11%), and a small percentage (0.03%) still relies on kerosene. Wood is the dominant fuel (46.25%), and other minor sources include charcoal (0.10%), straw/shrubs/grass (0.63%), agricultural crop residues (25.96%), and animal dung (6.39%). The results reveal that only a small proportion of households (20.45%) are classified as "clean cooking fuel non-poor," indicating a limited adoption of cleaner cooking technologies in Bangladesh. Further analysis indicates a gradual increase in clean cooking fuel usage as wealth status improves. Only 0.25% of the poorest households use clean fuels, while the percentage increases to 0.68% in the "poorer" category, 3.92% in the "middle" wealth category, and 24.51% in the "richer" category. Among the wealthiest households, 70.64% use clean cooking fuels. The study highlights the urgent need for policymakers in Bangladesh to address clean cooking fuel poverty by implementing measures like subsidies, awareness campaigns, and infrastructure development to promote cleaner cooking technologies, thereby improving public health and environmental sustainability.
该研究根据能源阶梯假说探讨了孟加拉国家庭的清洁烹饪燃料贫困问题,该假说认为,随着收入的增加,家庭会转向使用更清洁的烹饪燃料。2017-18年孟加拉国人口和家庭调查(BDHS)的数据显示,20.45%的家庭使用先进或更清洁的烹饪燃料,而大多数(79.23%)仍然依赖原始或传统的烹饪燃料。使用电力的比例非常小(0.57%),而使用液化石油气的比例略高(6.96%)。沼气的使用很少(0.11%),还有一小部分(0.03%)仍然依赖煤油。木材是主要的燃料(46.25%),其他次要来源包括木炭(0.10%),秸秆/灌木/草(0.63%),农作物秸秆(25.96%)和动物粪便(6.39%)。结果显示,只有一小部分家庭(20.45%)被归类为“清洁烹饪燃料非贫困”,这表明孟加拉国采用更清洁的烹饪技术的程度有限。进一步分析表明,随着财富状况的改善,清洁烹饪燃料的使用逐渐增加。在最贫穷的家庭中,只有0.25%的家庭使用清洁燃料,而在“较贫穷”类别中,这一比例上升至0.68%,在“中等”财富类别中为3.92%,在“较富裕”类别中为24.51%。在最富裕的家庭中,70.64%的家庭使用清洁的烹饪燃料。该研究强调,孟加拉国的政策制定者迫切需要通过实施补贴、宣传活动和基础设施建设等措施来解决清洁烹饪燃料贫困问题,以推广更清洁的烹饪技术,从而改善公众健康和环境可持续性。

Pakistan is the world’s 5th most populated country. This growing population is causing numerous social and environmental problems. By the increase in population, energy demand is increasing day by day. Pakistan, where majority of the population is living in rural areas is using uncleaned cooking fuel due to which CO2 emission is increasing that is further a cause of environmental degradation. Based on the data (for the period from 1980 to 2019) of World Development Indicators, this study intends to examine the association between urban population, and energy use with CO2 emission. Unit root test was applied to check stationarity of data and after checking the stationarity status of variables, ARDL (Auto regressive distributive lag model) techniques was applied on data. The outcomes of the study showed that trade openness, urbanization, and energy consumption have significant and positive effects on environmental degradation.  This study suggest that government must plan population and take steps towards the use of clean cooking fuels to control environmental degradation.
巴基斯坦是世界第五大人口大国。不断增长的人口造成了许多社会和环境问题。由于人口的增加,对能源的需求日益增加。巴基斯坦的大多数人口生活在农村地区,由于使用未清洁的烹饪燃料,二氧化碳排放量正在增加,这进一步造成了环境退化。基于世界发展指标(World Development Indicators) 1980 - 2019年的数据,本研究旨在探讨城市人口、能源使用与二氧化碳排放之间的关系。采用单位根检验检验数据的平稳性,在检验变量的平稳性状态后,对数据采用ARDL (Auto regressive distribudistribution lag model)技术。研究结果表明,贸易开放、城市化和能源消费对环境退化具有显著的正向影响。这项研究建议政府必须规划人口,并采取措施使用清洁的烹饪燃料来控制环境恶化。

Dhaka is the capital city of Bangladesh. Many people are migrating day by day. For their survival, the housing sector is being flourished day by day. The demand impacts the supplies. A number of people are doing housing business to support the situation, but on the contrary, they are grabbing a lot of green fields or water bodies from private properties and evacuating the owners. One of the ill examples is the Eastern Housing Pallabi 2nd Phase Project. The study aims to find the socio-economic status of the land owners and local inhabitants evicted from their land for the project. Concurring to the essential perception and data collected from diverse sources, roughly 350 families are migrated. Of The 45 relocated people placed under survey from the questionnaire survey by snowball sampling, it was found that most people were discovered to have been physically relocated from their original location. The income level, housing situation, and utility infrastructure are poorer than before the resettlement. They are too unaware of taking action against the developer for the deprivation in the land price. The research revealed various facets that shed light on how land developers abused the local population. Land developers, local oligarchs, local politicians, and locals were the four characters who actively participated in this relocation process and played various roles. A few scopes are identified to rehabilitate the victims to recover from their present situation. Government should adequately care about the reallocated people to compensate at the present rate considering the long period of suffering. There is scope for more intensive study on the topic.
达卡是孟加拉国的首都。许多人每天都在迁移。为了生存,房地产行业正日益繁荣。需求影响供给。许多人正在做住房生意来支持这种情况,但相反,他们正在从私人财产中攫取大量绿地或水体,并疏散业主。其中一个不好的例子是东部房屋帕拉比二期项目。这项研究旨在发现土地所有者和当地居民的社会经济地位,他们被驱逐出他们的土地。与从各种来源收集的基本看法和数据相一致的是,大约有350个家庭移徙。通过滚雪球抽样的问卷调查,我们调查了45个搬迁的人,发现大多数人都是从原来的地方搬迁过来的。收入水平、住房状况和公用设施都比安置前差。他们太不知道采取行动反对开发商剥夺土地价格。这项研究揭示了土地开发商如何虐待当地居民的各个方面。土地开发商、地方寡头、地方政客和当地人是积极参与这一搬迁过程并扮演不同角色的四个角色。确定了一些范围,以使受害者从目前的情况中恢复过来。考虑到长期的痛苦,政府应该充分关心重新分配的人口,以目前的比率进行补偿。对这个问题进行更深入的研究还有余地。

Kinetic study of microorganism’s growth in chicken manure (CM) when producing biogas is often studied for scale-up purposes. CM are considered as waste, and can cause serious environmental consequences when not properly disposed. The objective of the study is to know the characteristics of the bioreactor condition or environment responsible for CM degradation and biogas production. Methods involves serial dilution, pour plating, cell count and the determination of Monod parameters. POLYMATH regression results shows that CM of particle density 0.0163 g/cm3 gives a maximum specific growth rate, ?_max of 0.007316 hr^(-1) and half saturation constant, K_s of 3.8×?10?^8mg/l which points to substrate sufficiency for the survival of microorganisms and biogas production.
微生物在鸡粪(CM)中产生沼气时的生长动力学研究通常是为了扩大规模而进行的。CM被视为废物,如果处置不当,会造成严重的环境后果。该研究的目的是了解生物反应器条件或环境的特征,负责CM降解和沼气生产。方法包括连续稀释、倒镀、细胞计数和测定Monod参数。POLYMATH回归结果表明,当颗粒密度为0.0163 g/cm3时,最大比生长率为0.007316 hr^(-1),半饱和常数K_s为3.8× 10?^8mg/l,这表明底物足以使微生物存活和产生沼气。

Energy insufficiency is disturbing the improvement of Bangladesh. Since the sun light is not available always and the breeze does not blow constantly, solar and wind power alone are weaker power sources. Coupling solar as well as wind power sources along with storage batteries making up the full duration of time in the absence of wind or sun light supplies a pragmatic shape of power generation. In Bangladesh, breeze is not available most of the places. Only in the coastal areas, wind is sufficient to produce electricity. However, sunlight is available all over the year here. Although solar and wind alone power station has installed here but solar-wind cascading power station has not been installed yet.
能源不足阻碍了孟加拉国的发展。由于阳光不是总是可用的,微风也不是一直吹,单独使用太阳能和风能是较弱的能源。结合太阳能和风能以及储能电池,在没有风或阳光的情况下,提供了一种实用的发电形式。在孟加拉国,大部分地方都没有微风。只有在沿海地区,风力才足以发电。然而,这里一年四季都有阳光。虽然这里已经安装了单独的太阳能和风能发电站,但尚未安装太阳风级联发电站。

Economic Growth is a prominent factor to affect the energy consumption of Pakistan. This study tends to explore the influence of GDP growth of sectoral growth, agricultural, industrial and service sector on the level of energy consumption fossil fuel in Pakistan from 1990 to 2019 long period of time. The data was obtained from WDI (World Development Indicators).  ARDL (Auto Regressive Distributive Lag Model) econometric model was designed to look into the impacts of fossil fuel or energy consumption on Pakistan’s economic growth in both the short-run and long-run. Results revealed negative impacts of energy consumption or the use of fossil fuel on industry, personal expenditures, and exports of goods and positively affect agriculture and services and model is significant. These results showed that that economic expansion plays important role to increase energy consumption of Pakistan.
经济增长是影响巴基斯坦能源消费的一个突出因素。本研究旨在探讨1990年至2019年长时间内巴基斯坦部门增长、农业、工业和服务业GDP增长对化石燃料能源消费水平的影响。数据来自WDI(世界发展指标)。ARDL(自动回归分配滞后模型)计量经济模型旨在研究化石燃料或能源消耗对巴基斯坦短期和长期经济增长的影响。结果表明,能源消费或化石燃料的使用对工业、个人支出和商品出口的负面影响显著,对农业和服务业的正向影响显著。这些结果表明,经济扩张对巴基斯坦能源消费的增加起着重要作用。
