Western Osprey (Pandion haliaetus) is a resident breeding species in the United Arab Emirates (UAE). Osprey breed from December to March on offshore and nearshore islands and coastal sites across the country. Approximately 90% of the breeding population is found in Abu Dhabi Emirate, making it a critical area for conservation efforts. Due to its significance, Western Osprey has been listed as an Endangered (EN) species in the Abu Dhabi Redlist of Species. In 2023, an Emiratewide comprehensive survey was conducted, covering all coastal sites, as well as nearshore and offshore islands in Abu Dhabi. This was the first such comprehensive census of breeding Ospreys in Abu Dhabi. Data were collected using a customized mobile application with a focus on geo-referencing and photographing all nest structures. Of a total of 339 located nests across more than 60 coastal and island territories, 127 were active. Moreover, 44% (n=148) of all nests were observed on artificial platforms intentionally installed at different breeding territories to support nesting. Whereas 39% (n=133) were built naturally on ground and 17% (n=58) were observed on abandoned high-rise structures. The breeding population of osprey in the UAE is estimated to be 110 breeding pairs. The study established that current breeding population of Ospreys in Abu Dhabi Emirate stands at 127 breeding pairs. This stable breeding population of Osprey indicates the overall well-being of UAE’s coastal and marine environments. The Abu Dhabi Environmental Agency continues to monitor and enforce conservation measures to ensure the protection of this regionally important species and its habitats.

BackgroundAbu Dhabi, a part of the United Arab Emirates, is situated in an arid region where water scarcity is a significant concern. The residential sector in Abu Dhabi consumes a large portion of the available water resources, leading to a critical need for effective water management strategies. This study aims to understand the relationship between water tariffs and water consumption in the residential sector in Abu Dhabi. It employs an integrated fuzzy logic model, a form of artificial intelligence, to assess the impact of water tariffs on water consumption. The model includes variables such as water tariffs, the level of water awareness, the level of water behavior, and the level of technology use. The objective of these variables is to evaluate their impact on the water-saving index, which represents the ratio of daily water consumption per capita in Abu Dhabi to the global average.ResultsThe findings of this study, based on a survey measuring the level of water awareness, behavior, and technology use, revealed a potential strategy for reducing water consumption in Abu Dhabi’s residential sector. It was observed that increasing water tariffs, while maintaining current levels of water awareness, behavior, and technology use, could lead to a reduction in water consumption. However, it was also found that the impact of further tariff increases on water conservation diminishes after a certain threshold, indicating the necessity of a balanced approach in tariff adjustment. Interestingly, the study also highlights that Abu Dhabi residents demonstrate high levels of water behavior and technology use, indicating a positive trend toward water conservation.ConclusionsThis study emphasizes the importance of increasing water awareness among Abu Dhabi residents as a means to foster sustainable water consumption practices. While water tariffs can contribute to reductions in water consumption, the effects tend to decrease beyond a certain point. Therefore, a comprehensive approach involving water tariffs, increased water awareness, and the adoption of water-saving technologies may be the most effective strategy for water conservation. The insights from this study extend beyond Abu Dhabi and offer valuable guidance for addressing water conservation challenges worldwide. It highlights the importance of adopting a multi-faceted approach in water management, and the potential for such strategies to have international relevance in the pursuit of sustainable water consumption.

The perception in the Water and Electricity Department, Abu Dhabi, UAE, has grown stronger on judicious monitoring by a dedicated system of the operation of switching, regulating and protection equipment. Due to the degree of success in fault analysis depending heavily on the accuracy of data captured by the recording system used, the application of standalone fault recorders is now entering a new era on utility power systems. As a result of their design and manufacture being perceived with innovative hardware architectures and software breakthroughs, fault recorders have become more powerful in application and taken a winning place as the mainstay of information recording at every power station and grid substation built by the department. The focal point of this paper is the summary account of technical perspectives put into design and engineering aspects of the new fault recording facilities.

Water and land-use tension are growing with the growing population of the world especially in arid region. To develop an efficient, sustainable, and integrated water and land-use resource management policy, accurate and complex information about available resources and demand centers is required. Geographical information system (GIS) provides a means of representing the real world through integrated layers of constituent spatial information using overlaying and indexing operations. In Abu Dhabi, Water Resources Information System (AWRIS) was developed. AWRIS is a centralized, GIS-based, Web-enabled integrated information management system that allows storage and management of all water resource information. The system integrates a comprehensive set of tools and applications that facilitate the efficient management of the water resources of the Emirate. All historical water resource information from more than ten existing databases and 10,000 Excel workbooks have now been compiled, quality controlled, and migrated into the central database. AWRIS is built as an Integrated Information Management System and hence designed to improve productivity by linking all relevant applications for data handling to a centralized data repository and management system. This paper outlines the main features of AWRIS which are three-folds. First, it provides full support for the Arabic language. Second, it is the first of its kind in bringing unrestricted data types into a centralized information management system, and third, it provides a wide range of tools to effectively manage information on water resources.
