The United Nations, through its subsidiary agency United Nations Children's Fund (UNICEF), has put in such resources to curb infant mortality in pursuit of the Sustainable development goals (SDG). Nevertheless, the issue of under-five mortality is still persistent in so many developing countries, especially in sub-Saharan Africa. Therefore, this study investigated the long-term and short-term impacts of solid waste, urbanization, and pollution on under-five mortality, employing the Autoregressive distributed lag (ARDL) and the dynamic Autoregressive distributed lag (DARDL) models for the empirical investigations and robustness checks, respectively. The study found that there is significant cointegration between the interest variables. While key findings from the DARDL results revealed that pollution, urbanization, and solid waste have long-term significant positive impacts on under-five mortality in Nigeria, the short-run outcome shows that urbanization and solid waste had a significant positive impact on under-five mortality, while pollution was statistically insignificant. Moreover, lead exposure showed a significant long-term positive and short-term negative impact on under-five mortality in Nigeria. Furthermore, the DARDL simulations show higher long-run shocks and variations as compared to the short run. Thus, CO2 emissions, urbanization, and solid waste encourage under-five deaths in Nigeria. The study recommends, among other things, the enactment of environmental laws that will curb CO2 emissions in the country while also strengthening the existing ones, discourage indiscriminate solid waste disposal, and encourage investment in clean technologies and modern healthcare facilities in urban areas of Nigeria.

联合国通过其附属机构联合国儿童基金会(UNICEF)投入了大量资源来降低婴儿死亡率,以实现可持续发展目标(SDG)。然而,在许多发展中国家,尤其是撒哈拉以南非洲地区,五岁以下儿童的死亡率问题仍然持续存在。因此,本研究分别采用自回归分布滞后模型(ARDL)和动态自回归分布滞后模型(DARDL)进行实证研究和稳健性检验,探讨了固体废物、城市化和污染对五岁以下儿童死亡率的长期和短期影响。研究发现,相关变量之间存在明显的协整关系。自回归分布滞后模型的主要结果显示,污染、城市化和固体废物对尼日利亚五岁以下儿童死亡率有长期显著的正向影响,而短期结果显示,城市化和固体废物对五岁以下儿童死亡率有显著的正向影响,而污染在统计上不显著。此外,铅暴露对尼日利亚五岁以下儿童死亡率的长期积极影响和短期消极影响都很大。此外,与短期相比,DARDL 模拟显示出更高的长期冲击和变化。因此,二氧化碳排放、城市化和固体废物会增加尼日利亚五岁以下儿童的死亡率。该研究建议,除其他外,颁布环境法,以遏制该国的二氧化碳排放,同时加强现有的环境法,阻止任意处置固体废物,并鼓励对尼日利亚城市地区的清洁技术和现代医疗设施进行投资。

Climate change leading to Climate extremes in the twenty-first century is more evident in megacities across the world, especially in West Africa. The Greater Accra region is one of the most populated regions in West Africa. As a result, the region has become more susceptible to climate extremes such as floods, heatwaves, and droughts. The study employed the Coupled Model Intercomparison Project 6 models in simulating climate extreme indices under the Shared Socioeconomic Pathway scenarios (SSPs) over West Africa between 1979 and 2059 as exemplified by the Greater Accra region. The study observed a generally weak drought in the historical period and expected to intensify especially under SSP585 in Greater Accra. For instance, continuous dry days (CDD) reveal an increasing trend under the SSPs. Similarly, the overall projected trend of CDD over West Africa reveals an increase signifying a more frequent and longer drought in the future. The flood indices revealed a surge in the intensity and duration of extreme precipitation events under the SSPs in the region. For instance, R99pTOT and Rx5days are expected to significantly increase under the SSPs with intensification under the SSP245, SSP370, and SSP585. A similar trend has been projected across West Africa, especially along the Guinean coast. The study foresees a gradual and intensifying rise in heatwave indices over the Greater Accra region. The warming and cooling indices reveal an increasing and decreasing trend respectively in the historical period as well as under the SSPs particularly within urban centers like Accra and Tema. Most West African countries are projected to observe more frequent warm days and nights with cold nights and days becoming less frequent. Expected effects of future climate extreme indices pose potential threats to the water, food, and energy systems as well as trigger recurrent floods and droughts over Greater Accra. The findings of the study are expected to inform climate policies and the nationally determined contribution of the Paris Agreement as well as address the sustainable development goal 11 (Sustainable cities) and 13 (Climate action) in West Africa.

气候变化导致二十一世纪气候极端化,这在世界各地的特大城市,尤其是西非更为明显。大阿克拉地区是西非人口最多的地区之一。因此,该地区更容易受到洪水、热浪和干旱等极端气候的影响。这项研究采用了耦合模式相互比较项目 6 模型,以大阿克拉地区为例,模拟了 1979 年至 2059 年期间西非共享社会经济路径情景下的气候极端指数。该研究观察到,历史时期的干旱普遍较弱,预计会加剧,尤其是在大阿克拉地区的 SSP585 条件下。例如,在 SSPs 条件下,连续干旱天数(CDD)呈上升趋势。同样,西非连续干旱日的总体预测趋势也显示出增加的迹象,表明未来干旱将更加频繁,持续时间更长。洪水指数显示,在该地区的 SSPs 条件下,极端降水事件的强度和持续时间都会激增。例如,在 SSPs 条件下,R99pTOT 和 Rx5days 预计将显著增加,在 SSP245、SSP370 和 SSP585 条件下将加剧。预计整个西非,特别是几内亚沿海地区也会出现类似的趋势。该研究预测,大阿克拉地区的热浪指数将逐渐上升并加剧。升温指数和降温指数分别显示出历史时期和 SSPs 下的上升和下降趋势,尤其是在阿克拉和特马等城市中心。预计大多数西非国家将出现更频繁的暖日和暖夜,而寒夜和寒天则会减少。未来极端气候指数的预期影响将对水、食品和能源系统构成潜在威胁,并引发大阿克拉地区反复出现的洪水和干旱。预计研究结果将为气候政策和《巴黎协定》的国家贡献提供信息,并解决西非的可持续发展目标 11(可持续城市)和 13(气候行动)。

Abstract Gender equality and women’s empowerment are major concerns under Goal 5 of the United Nations' Sustainable Development Goals to be achieved by 2030. Therefore, microfinance institutions in developing nations have been working on these issues by providing loans to married women and others in need. As a result, this paper focuses on one such microfinance institution in Ethiopia, called ACSI (Amhara Credit and Saving Institution), and its role in fostering economic independence for married women and their involvement in various public social schemes. The study utilized a qualitative approach, collecting data through in-depth interviews (26), focus group discussions (1), and life histories from ACSI experts (4) and key informants from Women's and Children's Affairs (6). Specifically, the study focused on married women in Basona Werana Woreda and examined the impact of ACSI's credit services on their social conditions. The empirical findings of the study reveal that the social condition of married women clients has improved due to the credit services provided by ACSI. Women's social empowerment indicators have shown positive changes after utilizing the credit services. However, the study also identified challenges faced by the institution, such as a lack of adequate transportation means and a shortage of personnel to reach remote residents and fulfill their mission of improving the situation of vulnerable low-income and productive poor resident women. Additionally, cultural attitudes pose significant challenges to the social empowerment of women. The empirical implementation of this study provides insights into the achievements and hurdles that need to be addressed in enhancing economic security for married women through microfinance initiatives.
性别平等和妇女赋权是联合国2030年可持续发展目标5的主要关注点。因此,发展中国家的小额信贷机构一直致力于解决这些问题,向已婚妇女和其他有需要的人提供贷款。因此,本文将重点放在埃塞俄比亚的一个这样的小额信贷机构,称为ACSI(阿姆哈拉信贷和储蓄机构),以及它在促进已婚妇女经济独立和她们参与各种公共社会计划方面的作用。该研究采用了定性方法,通过深度访谈(26)、焦点小组讨论(1)和ACSI专家(4)和妇女儿童事务关键线人(6)的生活史收集数据。具体而言,该研究侧重于Basona Werana Woreda的已婚妇女,并检查了ACSI的信贷服务对其社会状况的影响。研究的实证结果显示,已婚女性客户的社会状况因ACSI提供的信贷服务而有所改善。利用信贷服务后,妇女社会赋权指标出现积极变化。然而,该研究也确定了该机构面临的挑战,例如缺乏足够的交通工具和人员短缺,无法接触到偏远地区的居民并履行其改善脆弱的低收入和生产性贫穷居民妇女状况的使命。此外,文化态度对赋予妇女社会权力构成重大挑战。本研究的实证实施提供了通过小额信贷举措加强已婚妇女经济安全方面需要解决的成就和障碍的见解。

Abstract The wine industry has evolved thanks to the introduction of digital technologies in every aspect of the wine production chain and the emerging need of the food industry for qualitative, sustainable, and safe products. As a result, the incorporation of digital services that facilitate access to related data of wine products is crucial for wine enterprises to increase their competitiveness, customer loyalty, and market share in this highly competitive domain. In this work, we present the Message-in-a-Bottle (MiB) ecosystem, which exploits multi-dimensional and multi-sourced data for creating engaging and interactive stories around wine labels. We especially focus on the sustainability and safety issues in the wine industry and showcase how MiB addresses them. The ecosystem is developed in the context of the MiB project and has already started to be available in the market through the Lyrarakis wine enterprise.
由于数字技术在葡萄酒生产链的各个方面的引入,以及食品行业对质量、可持续和安全产品的新需求,葡萄酒行业得到了发展。因此,在这个竞争激烈的领域,葡萄酒企业要想提高竞争力、提高客户忠诚度和市场份额,整合数字化服务,方便获取葡萄酒产品的相关数据至关重要。在这项工作中,我们提出了瓶中信息(MiB)生态系统,它利用多维度和多来源的数据来创建围绕葡萄酒标签的引人入胜的互动故事。我们特别关注葡萄酒行业的可持续性和安全问题,并展示MiB如何解决这些问题。该生态系统是在MiB项目的背景下开发的,并且已经开始通过Lyrarakis葡萄酒企业在市场上提供。

Abstract This paper explores the role of hydrogen fuel cell vehicles (HFCVs) in helping to meet global climate goals of limiting long-term greenhouse gas (GHG) emissions to 1.5 °C. Employing the GREET Model and data from the International Energy Agency (IEA), the study comprehensively compares the full fuel-cycle emission profiles of HFCVs and battery electric vehicles (BEVs). The paper conducts an in-depth examination of the interplay between the carbon intensity of the electric grid and the resulting GHG emissions within the context of refueling HFCV vehicles via electrolyzers, and the analysis draws a comparison to BEVs charged using the same electric grid. The study finds that while emissions for BEVs increase, emissions for HFCVs are significantly larger when HFCVs are refueled from retail outlets producing hydrogen via electrolysis from grid electricity—a finding that was not previously reached in the current literature. The research underscores that countries operating electric grids characterized by high GHG emissions or lacking robust pathways to emission reduction would face suboptimal outcomes by adopting HFCVs powered by hydrogen sourced from distributed grid electricity generation. The gCO2e/mi for BEVs and HFCVs are also calculated when the electricity is produced from renewable energy resources. When electricity is derived from renewable energy sources, it becomes evident that the gCO2e/mi for both HFCVs and BEVs converge towards ‘zero’. The emission metric of gCO2e/mile for a HFCV refueled with the hydrogen produced from natural gas via steam methane reforming (SMR) without carbon capture utilization and storage (CCUS), stands at 105 gCO2e/mile, whereas in the absence of CCUS, it escalates notably to 247 gCO2e/mile, an approximate 150% increase in stark contrast to CCUS inclusion. This quantitative portrayal serves to underscore the substantial potential for curtailing carbon footprints achievable through the integration of CCUS, thereby amplifying its significance within the realm of hydrogen-based transportation and the broader purview of climate change mitigation endeavors. In order to provide a comprehensive perspective, the study delves into the examination of hydrogen production pathways and associated costs for the years 2021, 2030, and 2050. The forecasted supply costs are elucidated, particularly in relation to the potential hydrogen supply originating from variable renewable energy (solar PV and wind) sources and from CCUS-equipped hydrogen production facilities (considering the project pipeline of projects upto 2030). These factors are of substantial importance in shaping the hydrogen supply landscape and subsequently influencing the adoption of HFCVs in the market. The study also examines the cost implications of hydrogen delivery for varying transportation distances (for 2030), acknowledging their important role in the broader context.

摘要:本文探讨了氢燃料电池汽车(HFCVs)在帮助实现将长期温室气体(GHG)排放限制在1.5°C的全球气候目标中的作用。该研究采用GREET模型和国际能源署(IEA)的数据,全面比较了氢燃料电池汽车和纯电动汽车(bev)的全燃料循环排放曲线。本文深入研究了在通过电解槽为氢燃料电池汽车加油的情况下,电网碳强度与由此产生的温室气体排放之间的相互作用,并将其与使用相同电网充电的纯电动汽车进行了比较。研究发现,虽然纯电动汽车的排放量增加了,但当氢燃料汽车从零售店通过电网电力电解生产氢气时,氢燃料汽车的排放量会显著增加——这是目前文献中尚未发现的一项发现。该研究强调,运营以高温室气体排放为特征的电网或缺乏强有力的减排途径的国家,如果采用由分布式电网发电的氢动力氢燃料汽车,将面临次优结果。当电力来自可再生能源时,也计算了纯电动汽车和氢燃料电池汽车的gCO2e/mi。当电力来自可再生能源时,氢燃料电池汽车和纯电动汽车的gCO2e/mi明显趋近于“零”。以天然气蒸汽甲烷重整(SMR)生产的氢气为燃料的氢燃料汽车,在没有碳捕集利用和封存(CCUS)的情况下,每英里二氧化碳当量的排放指标为105克二氧化碳当量,而在没有CCUS的情况下,二氧化碳当量显著上升至247克二氧化碳当量/英里,与加入CCUS形成鲜明对比,增加了约150%。这一定量描述强调了通过整合CCUS可实现的减少碳足迹的巨大潜力,从而扩大了其在氢基运输领域和更广泛的减缓气候变化努力范围内的重要性。为了提供一个全面的视角,该研究深入研究了2021年、2030年和2050年的制氢途径和相关成本。预测的供应成本被阐明,特别是与来自可变可再生能源(太阳能光伏和风能)来源和配备ccus的氢气生产设施的潜在氢气供应有关(考虑到2030年的项目管道)。这些因素在塑造氢供应格局并随后影响氢燃料电池汽车在市场上的采用方面非常重要。该研究还考察了不同运输距离(2030年)氢气输送的成本影响,承认它们在更广泛的背景下的重要作用。此外,还讨论了可变可再生能源整合带来的挑战,以及有效储能解决方案的必要性。这一论述在能源转型的总体框架内展开,其显著特征是太阳能光伏和风能的优势。这些方面错综复杂的相互作用在塑造未来中长期氢供应动态的轨迹中起着关键作用。
