The elasmobranch fauna was studied in the Khor Faridah region of Abu Dhabi, which is a mangrove-dominated inshore habitat historically reported to host a diversity of elasmobranch species. A stereo-baited remote underwater video system (Stereo-BRUVS) survey was conducted from September 2021 to August 2022 to assess the species diversity and relative abundance of elasmobranch fishes. A total of 12 elasmobranch taxa were encountered during the study, consisting of five rays (Myliobatiformes), four sharks (Selachii), two wedgefish and one guitarfish (Rhinopristiformes). The area was dominated by honeycomb-patterned rays in the genus Himantura and the Critically Endangered Arabic whipray Maculabatis arabica. Since Himantura uarnak and H. leoparda could not be reliably distinguished from footage, all sex- and size-based results are reported for a combined Himantura species complex and should be interpreted cautiously. Furthermore, the broad size range of individuals found in the area highlights its importance to all life stages of these taxa. This underlines the need for a conservation strategy to avoid detrimental changes to the elasmobranch fauna due to ongoing coastal development.

Abstract. The exponential growth of Earth observation (EO) data has created an urgent need for scalable, artificial intelligence (AI)-driven geospatial analytics platforms. Traditional GIS systems require specialized expertise, limiting their accessibility and usability for decision-makers. To address these challenges, the gIQ platform was developed as a Public-Private Partnership (PPP) initiative between the UAE Space Agency and Space42. gIQ integrates AI-powered geospatial analytics, cloud computing, and a marketplace for third-party applications, democratizing access to geospatial intelligence. This paper presents gIQ as a PPP success story, outlining its technical architecture, data acquisition pipeline, AI-driven insights, and business model. The platform leverages multi-source satellite data, AI-powered classification, real-time monitoring, and interactive visualization tools to deliver actionable geospatial intelligence. A marketplace model further enhances the ecosystem by enabling third-party developers to monetize AI models and geospatial services. The impact of gIQ extends beyond technological advancements. By bridging government, private sector, and research stakeholders, gIQ accelerates innovation in urban planning, environmental monitoring, and commercial space applications. The paper also discusses policy considerations, regulatory frameworks, and commercialization pathways that ensure the long-term sustainability of PPP-driven geospatial platforms (UAE Government, 2022). Finally, we outline future directions for expanding gIQ’s capabilities through cross-border PPPs and AI-powered decision support systems.

While they are important, local or catchment-level conservation efforts are by themselves unlikely to bend the curve of dramatic global-scale biodiversity loss in rivers, lakes, and freshwater wetlands. Other interventions will also be required, especially those that address the underlying socio-economic drivers of freshwater ecosystem degradation. Such drivers often manifest through decisions made at national or international scales by policymakers and business leaders in sectors including water resource management, agriculture and food production, energy generation, and inland fisheries. Few analyses have traced the impacts of such decisions on freshwater ecosystems and biodiversity, and the evidence base provides scant insight into effective approaches for addressing these underlying drivers. We begin to address this strategic knowledge gap by describing key policy and business sectors that the conservation and science communities should engage to address the systemic drivers of global freshwater biodiversity loss. Drawing on diverse experiences of international policy and business discourses and applied freshwater sciences, we provide an overview of international sector-specific risks and opportunities for freshwater conservation and propose potential priorities for engagement. We reflect on actions the freshwater sciences community can take to respond to these risks and opportunities, and we suggest priorities to shape a more systemic, driver-focused approach to freshwater conservation research that can support the integration of freshwater biodiversity considerations into policy and business decisions.

With a deficit of about 20 BCM in 2022, Egypt faces a severe water shortage due to rapid population growth (109.3 million in 2022). Egypt launched a program to utilize non-conventional water sources, like treated wastewater, agriculture drainage water, and desalination. Egypt is expanding its non-conventional water resources, boosting desalination capacity from 86,000 m3/day in 2015 to 680,000 m3/day in 2022, with plans to reach 1,250,000 m3/day by 2025. Despite the improvements in desalination technologies and cost, its high energy use and environmental impacts are still limiting its use. Egypt’s desalination relies on grid electricity, but renewable energy is crucial for remote areas where no electricity grid exists. Scaling up renewable energy in desalination faces challenges like land availability and high costs. GIS was used for optimal site selection for a brackish groundwater solar desalination plant in the Western North Nile Delta. Factors like solar radiation, groundwater quality, aquifer potentiality, geology, and seawater intrusion were carefully assessed. An evaluation of a sustainable 1000 m3/day solar-powered RO desalination pilot plant’s economic and technical viability is provided, along with its performance assessment. Limitations, challenges, and potential improvements are discussed. The study finds that RO–PV desalination for brackish groundwater is technically mature, with competitive Capex costs (USD 760-USD 850/m3) and low Opex (USD 0.55–USD 0.63/m3). Solar desalination for brackish groundwater with salinity less than 23,000 ppm can reduce energy consumption to 3.6–4.2 kWhr/m3. Water storage and hybrid systems with solar and conventional energy are suggested to enhance efficiency. This implies a growing market for small- to medium-scale RO solar-powered desalination in remote areas in the near future.

Coastal ecosystems are integral to global carbon cycling and are increasingly recognised for their role in mitigating climate change. Within these ecosystems, the dynamics of carbon storage are diverse, varying significantly across different habitats. However, existing management strategies often focus predominantly on vegetated habitats neglecting the contributions of non-vegetated areas. We address this knowledge gap by providing a quantitative spatial assessment of carbon storage across coastal seascapes varying in plant biomass. Our comprehensive multi-habitat inventory of carbon stocks in the United Arab Emirates confirmed that mangroves are the largest carbon-storing habitat per hectare (94.3 t/ha), followed by saltmarshes (63.6 t/ha), microbial mats (51.6 t/ha), mudflats (46.8 t/ha), seagrass (32.5 t/ha), and coastal sabkha (31.0 t/ha).Mean carbon content in the top 50 cm of mangrove soils (53.9 t/ha) was similar to saltmarshes (52.7 t/ha), microbial mats (51.6 t/ha), and mudflats (46.8 t/ha). We highlight the importance of including non-vegetated habitats in carbon accounting and management strategies. Our findings suggest that a more context-specific whole-system approach is essential for guiding effective ecosystem management and designing ecologically meaningful Nature-based Solutions (NbS). Adopting this broader perspective in NbS can ensure more comprehensive conservation and restoration outcomes, which not only protect and enhance blue carbon ecosystems but also contribute to broader ecological and social benefits. This approach is pivotal for advancing our understanding of interconnected coastal ecosystems and their role in climate change mitigation.

We present new data on the distribution of Lactuca species and review the currently documented data on the genus in the United Arab Emirates (UAE). L. serriola L. is recorded for the first time from Abu Dhabi Emirate. L. dissecta D. Don, L. serriola, and L. orientalis (Boiss.) Boiss. were already reported from other emirates. Detailed morphological descriptions, types, distribution maps, and a key to Lactuca species in the UAE are included. We also highlight the deficiency of the documentation with herbarium specimens in the UAE.

This research assessed the environmental impact of cement silos emission on the existing concrete batching facilities in M35-Mussafah, Abu Dhabi, United Arab Emirates. These assessments were conducted using an air quality dispersion model (AERMOD) to predict the ambient concentration of Portland Cement particulate matter less than 10 microns (PM10) emitted to the atmosphere during loading and unloading activities from 176 silos located in 25 concrete batching facilities. AERMOD was applied to simulate and describe the dispersion of PM10 released from the cement silos into the air. Simulations were carried out for PM10 emissions on controlled and uncontrolled cement silos scenarios. Results showed an incremental negative impact on air quality and public health from uncontrolled silos emissions and estimated that the uncontrolled PM10 emission sources contribute to air pollution by 528958.32 kg/Year. The modeling comparison between the controlled and uncontrolled silos shows that the highest annual average concentration from controlled cement silos is 0.065 μg/m3, and the highest daily emission value is 0.6 μg/m3; both values are negligible and will not lead to significant air quality impact in the entire study domain. However, the uncontrolled cement silos’ highest annual average concentration value is 328.08 μg/m3. The highest daily emission average value was 1250.09 μg/m3; this might cause a significant air pollution quality impact and health effects on the public and workers. The short-term and long-term average PM10 pollutant concentrations at these receptors predicted by the air dispersion model are discussed for both scenarios and compared with local and international air quality standards and guidelines.

Abstract We present the first continuous observations of the extreme and far ultraviolet (EUV and FUV) dayglow emissions measured by Emirates Mars Ultraviolet Spectrometer (EMUS) onboard the Emirates Mars Mission. We found excellent agreement between the previous observations from the Hopkins Ultraviolet Telescope and recent observations by EMUS both in shape and magnitude. We presented the average disk brightness of major EUV and FUV emissions for about 10 months of data from April 2021 to February 2022. The solar activity was mild/minimum during the first half of the period presented in this study, but we noticed significant day‐to‐day variations in the major dayglow emissions independent of solar activity, indicating possible coupling from the lower atmosphere via waves/tides. The solar activity increased significantly during the second half of the study period. Our analysis showed that all major EUV and FUV emissions are highly correlated with solar forcing as well as seasonal changes.

The northwestern Indian Ocean hosts globally crucial marine biodiversity, which is relatively understudied.There has, however, been significant research and conservation effort focused on marine turtles across the region in recent decades.We undertook an exhaustive review of 251 relevant publications to extract and collate the current information concerning marine turtles.To ensure completeness, we received input on a preliminary draft from a large group of experts who have worked extensively in the region.Data presented here are from all 13 countries with significant coastlines in the region (Bahrain, Djibouti, Egypt, Eritrea, Iran, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, Sudan, United Arab Emirates, and Yemen) on occurrence, nesting biology, morphology, foraging areas, population status, threats, and relevant national legislation and international conservation strategies.The experts independently provided details on what they felt were the (1) most significant threats to marine turtles, (2) most critical knowledge gaps for marine turtle ecology, (3) impediments to practical conservation, and (4) essential strengths and opportunities in the region.
