Anthropogenic or Artificial light at night (ALAN) pollution, or more simply light pollution, is an issue of increasing concern to the general public, as well as to scientists and politicians. However, although advances have been made in terms of scientific knowledge, these advances have not been fully transferred to or considered by politicians. In addition, illumination of stone monuments in urban areas is an emerging contribution to ALAN pollution that has scarcely been considered to date. This paper presents a literature review of the topic of light pollution and related policies, including a bibliometric analysis of studies published between 2020 and 2022. The prevailing legislation in Europe regarding the regulation of outdoor lighting, which emphasises the complexity of controlling light pollution, is summarised and the regulation of monumental lighting in Spain is discussed. Findings concerning the impact of ALAN on biodiversity in urban areas, and the promising biostatic effect of ornamental lighting (halting biological colonization on stone monuments, mainly caused by algae and cyanobacteria) are described. Finally, trends in monument illumination and policymaking towards environmentally sustainable management are considered.

Background: Early detection and initiation of care is crucial to the survival and long-term well-being of children living with HIV (CLHIV). However, there remain challenges regarding early testing and linking of CLHIV for early treatment. This study examines the progress made towards achieving the 95-95-95 HIV indicators and associated factors among CLHIV < 15 years in South Africa.

Background: The WHO considers anemia in pregnancy a severe public health issue when prevalence surpasses 40%. In response, we conducted a systematic review and meta-analysis to examine anemia among pregnant women in Egypt, focusing on its prevalence, determinants, and associated complications.
Methods: We conducted a systematic literature search for studies published between January 1, 2010, and August 18, 2024, to identify studies from Egypt reporting on anemia in pregnant women, including its prevalence, associated determinants, and complications.

Soil erosion in North Africa modulates agricultural and urban developments as well as the impacts of flash floods. Existing investigations and associated datasets are mainly performed in localized urban areas, often representing a limited part of a watershed. The above compromises the implementation of mitigation measures for this vast area under accentuating extremes and continuous hydroclimatic fluctuations.

Providing different grades of water is a promising solution to address the challenges of urban water supply, including water quality, quantity, and energy consumption. However, quantifying the effectiveness of this strategy and understanding its economic, environmental, and social impacts remain significant challenges. This study introduces a simulation-based method to predict household water use and evaluate the applicability and sustainability of the water supply system.

Some research has studied the carbon footprints of the multinational enterprises (MNEs) in the global value chains (GVCs). However, currently there are few studies have studied the carbon footprints of the foreign invested firms (FIFs) distributed in different provinces in China's domestic value chains (DVCs). This paper has used China's inter-provincial input-output table distinguishing domestically owned enterprises (DEs), Hong Kong, Macao, and Taiwan (HMTs) invested enterprises and other foreign invested enterprises (FIEs) to study the carbon footprints of the FIFs in China's DVCs and further analyzed the driving factors of the carbon footprints change.
