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.

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.

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.

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.

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. The challenges posed by the integration of variable renewable energy sources are al
