Abu Dhabi, the capital of the United Arab Emirates, continues to change at a rapid pace in response to city branding efforts. Significant investments in the city’s urban infrastructure and its built environment are widespread, as Abu Dhabi attempts to compete on the world stage and lure in tourists, corporations, and investors alike. City planners have been busy updating the city’s urban spaces and streetscapes. They have been transforming it into a sleek and modern contemporary Arab city with a ‘high-end’ feel – which has been successful thus far. As a result, Abu Dhabi’s name has become synonymous with luxury, and the city’s overall quality, livability, and resilience have improved significantly. At the other end of the spectrum, the lower-income segments of the society appear to be missing from the urban planning effort. Some of the urban upgrading interventions might be unintentionally taking away some of the vibrant and diverse aspects of informal street life. This is especially true in some areas, where monotonous and sterile newer environments and streetscapes are replacing the older, informal environments, mostly inhabited by lower-income workers. This paper takes a closer look at some of these older spaces and streetscapes in Abu Dhabi. Through a case study, it attempts to shed some light on some of these vibrant areas, which could potentially vanish soon. It also attempts to highlight the energetic nature of these streetscapes and bring this to the attention of city planners. The paper argues that valuable lessons could be learned from these informal spaces and that these lessons could contribute positively to future planning efforts in the city.

A survey of the coastal zone of Abu Dhabi identified 22 halophytes of which nine are tolerant to inundation by seawater. A preliminary assessment suggested that 3.550 km2 of saline land with a complete absence of natural vegetation was potentially suitable for the development of sustainable agro-ecosystems with halophyte crops and seawater irrigation. Such development plans, however, require the implementation of environmental impact assessments. The inter-tidal plant communities need special protection, as they are fragile, and economically and ecologically valuable.

Abstract This article presents an assessment of one of the earliest greywater reuse (GWR) experiences in Sharjah, United Arab Emirates (UAE). In 2003, the Sharjah Electricity and Water Authority (SEWA) imposed a compulsory GWR program on various categories of new buildings in the city. However, implementation of the program faced significant resistance and setbacks and remained limited to about 200 buildings, representing less than 2% water savings. In the analysis presented in this study, the need for GWR was assessed through analyzing SEWA's water supply and demand projections, conducting a 12-month water use survey of 285,000 Sharjah residents from about 140 nationalities, and identifying the areas in the city with intense water use. In addition, analysis and reforms of the various aspects of SEWA's GWR reuse policies and practice were presented and discussed. Reforming the policy to increase GWR to about 10% water savings can lead to significant reductions in desalinated water consumption and wastewater generation and consequently significant reductions in desalination cost (35 million USD/y), energy consumption (225,840 MWh/year) and CO2 emissions (120 ton/year). The case study presented in the article can serve as a reference to guide GWR policies and practice, especially for local authorities in developing countries.

Abstract Climate change may have severe consequences for urban areas and many cities, such as those situated on deltas, are already threatened. The paper claims that the solution for endangered areas is the embedding of urban climate resilience. The concept of resilience is put forward to bring a broad perspective to a city with an indication that the city is a complex system with developed relations, both inward and outward. Social and institutional aspects of these relations are highlighted as they have the highest potential to make the city resilient. The paper indicates three fundamental features of embedding the resilience of urban areas to climate change: network building, a strategic approach and implementing urban projects. A practical application of these fundamental features is evaluated using the case study of Rotterdam. The research shows the reliability of these bases and indicates key characteristics of each fundamental feature: the network should be multidimensional with solid institutional and interpersonal relations, the strategy should have a holistic approach and project implementation needs the engagement of all the city actors.

AbstractWithin the scope of urban climate modeling, weather analogs are used to downscale large-scale reanalysis-based information to station time series. Two novel approaches of weather analogs are introduced which allow a day-by-day comparison with observations within the validation period and which are easily adaptable to future periods for projections. Both methods affect the first level of analogy which is usually based on selection of circulation patterns. First, the time series were bias corrected and detrended before subsamples were determined for each specific day of interest. Subsequently, the normal vector of the standardized regression planes (NVEC) or the center of gravity (COG) of the normalized absolute circulation patterns was used to determine a point within an artificial coordinate system for each day. The day(s) which exhibit(s) the least absolute distance(s) between the artificial points of the day of interest and the days of the subsample is/are used as analog or subsample for the second level of analogy, respectively. Here, the second level of analogy is a second selection process based on the comparison of gridded temperature data between the analog subsample and the day of interest. After the analog selection process, the trends of the observation were added to the analog time series. With respect to air temperature and the exceedance of the 90th temperature quantile, the present study compares the performance of both analog methods with an already existing analog method and a multiple linear regression. Results show that both novel analog approaches can keep up with existing methods. One shortcoming of the methods presented here is that they are limited to local or small regional applications. In contrast, less pre-processing and the small domain size of the circulation patterns lead to low computational costs.
