The United Arab Emirates holds great historical importance, as evidenced by many archaeological sites, such as the Jebel Hafit Tombs and the Hili Archeological Park in Al Ain. At the western edge of Mutaredh Oasis, a major new archaeological site was discovered in 2023 during a construction project. Several important archeological features have been documented, including an earthen mosque and boundary walls, Iron Age irrigation systems, and a circular stone tomb dating to the Bronze Age. However, the eastern edge of the Mutaredh site has remained unexplored to date. Ground Penetrating Radar (GPR) has been proven to be a successful method in mapping archaeological remains. Accordingly, a high-resolution GPR survey was carried out to identify the continuity of the unearthed archeological elements and delineate new unexplored features. A comprehensive 3D model of buried archaeological features was constructed using the acquired high-resolution GPR data in the eastern part of the Mutaredh site. Several selected anomalies have been observed, similar to the uncovered features in the western part of the Mutaredh site and structures documented in other nearby archaeological sites. The geometry and extension of these anomalies have enabled the possible identification of a further two Bronze Age circular tombs, as well as the delineation of a system of water channels (falaj), and irrigation networks with tree pits from the Iron Age. Moreover, walls probably belonging to the Late Islamic Age are identified. These findings suggest that Mutaredh has been a site of intensive human activity from the Bronze Age through to the Late Islamic period. Given the density of identified anomalies, further significant features are anticipated to lie buried in the immediate surrounding areas, promising continued insights into the area’s rich archaeological heritage. The findings of this study may guide archaeologists to specific locations and assist in selecting the most appropriate excavation techniques for the verification stage.

The historic house of Sheikh Mohammed Bin Khalifa, Al Ain (Abu Dhabi, UAE) belongs to the World Heritage Cultural Sites. The courtyard and two rooms include mudbrick archaeological remains that are preserved in showcases for public display. The building lies in a hot desert climate and needs air conditioning to be comfortable. This paper is concerned with indoor showcases and their compatibility with the indoor climate. Sometimes, misting for condensation is generated on the glass panes for the temperature and humidity contrast between the room climate and the showcases that are embedded in the floor. When misting occurs, the remains cannot be viewed. This paper investigates indoor glass misting, the exchanges of heat and moisture between archaeological remains, showcases and rooms, and the results after a year of environmental monitoring. An aim is to assess the potential risks for the preservation of the remains, recognizing the frequency and severity of the conditions for condensation. Another aim is to discuss mitigation methodologies to avoid glass misting, e.g., (i) reducing the room cooling; (ii) raising the glass pane temperature with electrical devices; (iii) increasing air exchanges between showcases and rooms; (iv) adopting a combination of these methodologies.

# Background This paper estimates the costs and benefits of investing in education interventions and specific child marriage programs to reduce child marriage in India. Child marriage in India remains highly prevalent despite considerable progress in the last decade or more, associated, in particular, with a decline in poverty. The economic consequences of the COVID 19 pandemic are likely to reverse these gains, meaning that the interventions to reduce child marriage evaluated in this paper assume even greater importance. # Methods A literature search to identify interventions with costs and estimates of impact on reduction in child marriage for India, and other low and middle income countries was conducted. The costs and effectiveness of the interventions were modelled for India, and economic benefits of reducing school dropout rates and increasing secondary school completions were estimated. The ratio of the economic benefits to the intervention costs estimated gave the benefit-cost ratio. # Results The interventions resulted in an average benefit-cost ratio of 16.8. The interventions are projected to decrease the estimated marriage rate for girls aged 15–17 years for India from an estimated rate of 16.4% in 2020 by 7.5 percentage points by 2050, with education interventions targeting increased attendance being the larger factor. By 2030, the proportion of girls completing school is estimated to increase by 13 percentage points and productivity to have increased by 16.4%. # Conclusions The results indicate substantial economic and social gains to reducing child marriage by interventions that decrease school dropout rates, increase secondary school completions for girls, and address some of the broader social and cultural disadvantages they face in India. This has significant implications not only for their health, but also for the quality of the available economic opportunities and the possibility of attaining Sustainable Development Goal 5.
