Arab Middle Eastern Urbanization

This article explores urbanization in the Arab countries of the Middle East and covers contributions published in English. The literature offers a wide diversity of topics, some of which represent cross-cutting themes across the entire region (e.g., the diffusion of Dubai’s urbanization model throughout the Middle East under the “contemporary urbanization trends” theme) while others are context-specific to a sub-region (e.g., the Levant or the Arab Gulf), a country, or even a city (e.g., Beirut’s postwar reconstruction). A thematic presentation highlights the areas of concentration and those of omission that warrant further exploration vis-à-vis each context whether theoretically and/or empirically. Urban governance is one of the most broached topics, particularly the roles of civil society and the market. Indeed, studies abound on the political economy of place, namely the impacts of neoliberalism and globalization and the transfer of contemporary urbanization trends from the Gulf to the rest of the region. Paralleling this focus on high-end urbanization is a focus on urban informality whether in its strict form in Cairo, or in the form of refugee camps in Jordan, Lebanon, and Syria. Postwar reconstruction and place memory have received much attention and are connected, especially in Lebanon, to urban rehabilitation. Notably, the emphasis in the literature remains, for the most part, on capital cities with far fewer contributions on other urban centers within each sub-region/country. Also, while studies abound on urban heritage, there is a need for contributions that connect the rehabilitation of historic urban landscapes (HULs) to housing availability and affordability. In terms of omissions, there is a dearth in contributions pertaining to urbanization and environmental sustainability, particularly environmental planning, urban ecosystems, and ecological designs (nature-based solutions), and also climate change including risk and vulnerability assessments, mitigation (decreasing greenhouse gas emission), adaptation (urban systems’ adjustments to climate change), climate justice, and urban resilience. Throughout, there is little variation in the theoretical framing and the empirical methods among the abundant contributions. While the prevailing qualitative empirical approaches offer valuable insights, there is an evident lack of quantitative studies probably attributed to the challenges in the availability and accessibility of census and geospatial data. The latter may also be the reason for the near absence of urban morphological studies throughout the region.

In terms of climate change, Middle East and Arab countries cover a vast and diverse region with stark variations in natural resources, ecological footprints, and political priorities. It includes large oil and gas producing nations (the Gulf States) as well as resource-depleted countries (Jordan, Syria). Most countries rely on carbon energy, while a few have developed an alternative vision based on renewables (Morocco). It is home to both highly affluent countries (e.g., UAE) as well as poor and conflict-ridden societies (Iraq, the Levant, Yemen). Although the region as a whole is particularly vulnerable to climate change due to low levels of socio-ecological resilience, potential conflicts over natural resources (e.g., water), and almost chronic refugee and immigration crises, there are considerable differences in the region’s adaptive resources and mitigation strategies. This regional heterogeneity, however, is rarely reflected in the region’s climate change communication, which (with a few exceptions) tends to follow similar communicative patterns. Long-running social and religious conflicts in the Middle East have pushed climate change down the agenda of public opinion and news reporting in most Arab countries. Moreover, many Arab countries share a semi-authoritarian media system, which seems to exacerbate this tendency. In order to avoid crossing editorial redlines, climate change reporting is mostly copyedited from international news agencies. Local reporting is sparse as it may easily touch on sensitive issues concerning inadequate governance. Consequently, climate change has traditionally been covered as foreign news with a focus on international climate change negotiations—and hence limited relevance for a regional readership. However, new information technology and an increasing focus on raising awareness on climate change points toward alternative channels of climate change communication in Middle Eastern and Arab countries.

Simply understood as ‘seeking opportunities out of crises’, resilience seems to be a universal approach to cope with contemporary global challenges, such as changing climate, rapid urbanisation, loss of biodiversity, migrations, etc. As a majority of the current problems are of urban origin – i.e. they emerge in cities, where they also cause significant consequences on people, ecosystems and infrastructures, it is a city and its territorial sub-elements (district, neighbourhood, site, and building) that provide a prolific field for exploring the mechanisms towards resilient governance, planning and design. Under such an overarching agenda of urban resilience, in this paper, we focus on exploring the components of architectural and urban design as a tool for mitigating climate change. More precisely, as carbon dioxide emitted from the built environment is released into the atmosphere at an unprecedented rate, we explore the design patterns that help reduce CO2 emissions to finally lessen the vulnerability index of urban systems. Scrutinising the relationship between the climate change and construction industry, we elucidate the concepts like sustainable construction, green buildings, and design for climate, among others. Finally, through the assessment of the adaptive reuse project in London, this paper identifies strategies of sustainable architectural and urban design aimed at curbing the effects of climate change and helping increase urban resilience.

<p>Many observation-based and modelling studies have identified the Eastern Mediterranean and Middle East (EMME) region as a prominent climate change hot-spot. During the last half century, the region has warmed faster than the global mean, while at the same time changes in the hydrological cycle have been observed. Several studies suggest that these trends are projected to continue and intensify throughout the 21st century, depending on greenhouse gas emission scenarios. To assess climate change impacts on a regional and local level, future climate information of high quality and spatial resolution is required. To provide such information is the objective of CORDEX. The latest advancement of this World Climate Research Programme (WCRP) initiative includes the CORDEX-CORE set of regional experiments that aims at global coverage and was designed to provide regional-level information to the upcoming Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC). This state-of-the-art dataset is available at a spatial resolution of 0.22° (about 25 km). We have complemented this ensemble model data with those from two experiments of the MENA-CORDEX initiative that are available at the same resolution. Here, we have analyzed monthly data from 1971 to the end of the current century. We have adopted a multi-domain and multi-model ensemble approach that is found to add value by addressing shortcomings and reducing uncertainties. Our results corroborate and update existing estimations on the transition to drier and hotter conditions in the EMME region. Under a business-as-usual pathway (RCP8.5), the region-average warming at the end of the current century is expected to exceed 5 °C (with respect to the 1986-2005 reference temperature). On the contrary, under a strong mitigation pathway (RCP2.6) this warming can be limited to less than 1.5 °C. Summer warming is projected to exceed these values by 2-3 °C, favoring the conditions for unprecedented heatwaves. On average, precipitation changes are less robust and significant and range between 0 to -15% of the reference values, while locally stronger drying can occur, particularly under RCP8.5.</p>

Social and behavioral research is crucial for securing environmental sustainability and improving human living environments. Although the majority of people now live in urban areas, we have limited empirical evidence of the anticipated behavioral response to climate change. Using empirical data on daily household residential water use and temperature, our research examines the implications of future climate conditions on water conservation behavior in 501 households within the Portland (OR) metropolitan region. We ask whether and how much change in ambient temperatures impact residential household water use, while controlling for taxlot characteristics. Based on our results, we develop a spatially explicit description about the changes in future water use for the study region using a downscaled future climate scenario. The results suggest that behavioral responses are mediated by an interaction of household structural attributes, and magnitude and temporal variability of weather parameters. These findings have implications for the way natural resource managers and planning bureaus prepare for and adapt to future consequences of climate change.

One of major factors of deterioration in a microclimate of urban development in the conditions of the Rostov region, is degradation of landscapes owing to violation of water balance of the territory. In article the main reasons for violation of water balance which included natural features of the region, a consequence of anthropogenic influence, climatic changes, etc. are considered. Examples from the world practice of urban planning, which show the relevance and effectiveness of compensation for the effects of anthropogenic im-pacts and climate change using planning methods, are given. The experience of the United States, the Nether-lands, Canada and other countries that use water-saving technologies in planning is considered. The rela-tionship of urban planning and the formation of sustainable urban landscapes is shown. The integration of water-saving technologies into the urban environment can be a means of optimizing landscapes and a means of creating unique urban spaces. Reclamation of the urban landscape of low-rise buildings is a necessary step in creating a modern and comfortable urban environment in the conditions of the Rostov region. Meth-ods are proposed to compensate for negative changes in urban landscapes that can be applied at the stage of urban planning. As well as the proposed methods can be applied in the reconstruction of urban low-rise buildings. The considered methods concern not only urban landscapes, but also agricultural landscapes that surround small and medium-sized cities of the Rostov region. In article the author's concept of the organiza-tion of the low housing estate on a basis Urban- facies is submitted. Planning methods of regulation of water balance of the territory on the basis of models the ecological protective of landscapes are offered: an ecolog-ical core, an ecological corridor and an ecological barrier and also analogs from town-planning practice are considered. The reclamation of urban landscapes based on urban planning methods for regulating the water balance of the territory will allow creating unique urban spaces that are resistant to local climatic conditions and the possible consequences of climate change.

Ammonia (NH3), methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions from livestock farms contribute to negative environmental impacts such as acidification and climate change. A significant part of these emissions is produced from the decomposition of slurry in livestock facilities, during storage and treatment phases. This research aimed at evaluating the effectiveness of the additive “SOP LAGOON” (made of agricultural gypsum processed with proprietary technology) on (i) NH3 and Greenhouse Gas (GHG) emissions, (ii) slurry properties and N loss. Moreover, the Life Cycle Assessment (LCA) method was applied to assess the potential environmental impact associated with stored slurry treated with the additive. Six barrels were filled with 65 L of cattle slurry, of which three were used as a control while the additive was used in the other three. The results indicated that the use of the additive led to a reduction of total nitrogen, nitrates, and GHG emissions. LCA confirmed the higher environmental sustainability of the scenario with the additive for some environmental impact categories among which climate change. In conclusion, the additive has beneficial effects on both emissions and the environment, and the nitrogen present in the treated slurry could partially displace a mineral fertilizer, which can be considered an environmental credit.

Given that evolving urban systems require ever more sophisticated and creative solutions to deal with uncertainty, designing for resilience in contemporary landscape architecture represents a cross-disciplinary endeavor. While there is a breadth of research on landscape resilience within the academy, the findings of this research are seldom making their way into physical practice. There are existent gaps between the objective, scientific method of scientists and the more intuitive qualitative language of designers and practitioners. The purpose of this paper is to help bridge these gaps and ultimately support an endemic process for more resilient landscape design creation. This paper proposes a framework that integrates analytic research (i.e., modeling and examination) and design creation (i.e., place-making) using processes that incorporate feedback to help adaptively achieve resilient design solutions. Concepts of Geodesign and Planning Support Systems (PSSs) are adapted as part of the framework to emphasize the importance of modeling, assessment, and quantification as part of processes for generating information useful to designers. This paper tests the suggested framework by conducting a pilot study using a coupled sociohydrological model. The relationships between runoff and associated design factors are examined. Questions on how analytic outcomes can be translated into information for landscape design are addressed along with some ideas on how key variables in the model can be translated into useful design information. The framework and pilot study support the notion that the creation of resilient communities would be greatly enhanced by having a navigable bridge between science and practice.

The continuous growth of cities brings out various concerns for improved development and management of the multifaceted urban systems, including those of resilience and smartness. Despite the many significant efforts in the research field, both notions remain changeable, thus retaining the lack of commonly accepted conceptual and terminological frameworks. The paper’s research goals are to designate the current direct and indirect links in the conceptualizations and research trends of the resilience and smart city frameworks and to prove the potential of the conceptual convergence between them in the context of urban systems. The application of a semi-systematic literature review, including bibliometric evidence and followed by content analysis, has led to the observation that as the resilience discourse opens up to embrace other dimensions, including technology, the smart city research turns its interest to the perspective of urban protection. Therefore, both concepts share the goal for urban sustainability realized through specific capacities and processes and operationalized with the deployment of technology. The paper’s findings suggest that the conceptual and operational foundations of these two concepts could support the emergence of an integrated framework. Such a prospect acknowledges the instrumental role of the smart city approach in the pursuit of urban resilience and unfolds a new model for sustainable city management and development.
