Abstract:

The greater Cairo region is the most populated area in Egypt. The aquatic environment of the Nile River in this area is being affected by industrial activities. The study of the molecular structure of sediment may provide a good trace for such changes. Both Fourier transform infrared spectroscopy (FT-IR) and density functional theory (DFT) were used to study the effect of industrial waste disposal south of Cairo on the molecular structure of Nile River sediment. Four seasonal samples were collected from six sites covering 75 km along the Nile River. Grain sizes of 200 μm, 125 μm, 65 μm, and 32 μm, respectively, were examined. The results indicate that hydrated aluminum hydroxide controls the distribution of organic matter in the different grain sizes. Furthermore, the hydration of phenol may take place in grain sizes lower than 200 μm, which is indicated by the OH stretching at 3550 cm−1 and verified by the obtained model. The formation of metal carboxylate bonds at 1638 cm−1 (asymmetric) and 1382 cm−1 (symmetric) indicate the possible interaction between heavy metals and other organic structures, mainly humic substances.

Abstract:

Sustainable development (SD) has become a crucial challenge globally, particularly in developing countries and cities. SD of peri-urban areas (PUA) has been tackled by a limited number of studies, unlike that of urban areas or cities. The PUAs of Greater Cairo (GC) are no exception; no study had addressed the state of the PUAs in terms of SD. Thus, this study sought to measure and evaluate the progress towards the SD in the PUAs of Greater Cairo, Egypt. Thirteen indicators were extracted from selected documents of the competent international organizations to measure and evaluate the performance of SD in the study area. The study resulted in a variety of charts and maps to explain the progress of SD in each municipality of the PUAs and then classify these municipalities based on their performance in sustainability indicators. The results revealed a wide gap between PUAs’ municipalities and the urban core of Greater Cairo. These results can help urban planners and decision-makers to better recognize the underdeveloped areas on the Greater Cairo peripheries, and hence, to develop the appropriate strategies and policies to improve SD in such areas.

Abstract:

Several heatwaves (HWs) have been recorded in Egypt in recent years. Some of these HWs were mild, while others were severe and resulted in mortalities and morbidities. On the other hand, air pollution is considered a health issue in Egypt’s megacities, especially the capital city, Cairo, and its surroundings, the Greater Cairo (GC) region. In this study, we examine a number of HWs that have hit Egypt in recent years, along with the state of air quality, in terms of PM10, NO2, and O3, during the period of HW incidence, with a focus on the GC region. During the period of study, the frequency, intensity, and duration of HWs have been observed to increase. The total number of recorded HW events was 190, encompassing 376 HW days. The time series of daily mean NO2 showed no correlation with temperature during the months that experienced HWs cases. Conversely, PM10 and O3 concentrations exhibited a similar pattern as that of the daily maximum temperature. This increase in the two pollutant concentrations led to a degradation of the air quality, as demonstrated by the fact that the Air Quality Health Index went from “moderate risk”, on normal days, to “high risk” during the HWs.

Abstract:

Transportation has always been the backbone of development. Transit-oriented development (TOD) has been theorized, piloted and expanded increasingly in the past few decades. In this regard, this paper investigates the relationship between urban development, the transportation process, and the required implementation guidelines within fast-urbanizing cities, such as Cairo. After reviewing different related sustainable development theories, the study investigates pioneering case studies that have applied TOD and provided adequate implementation frameworks. The authors then extract and compare a set of required policies. The current Egyptian development paradigm is then discussed in relation to these enabling policies, focusing on Greater Cairo Region, Egypt. The authors debate previous development plans, progress, and newly proposed ones, focusing on the transportation process as the means for development. The study concludes with a set of required guidelines to ensure the integration of transportation with land-use planning, thus ensuring a more prosperous and inclusive urban development.

Abstract:

Greater Cairo Region (GCR) is the largest metropolitan area on the African continent and the Arab world. It accommodates 16.1 million inhabitants representing 19% of Egypt's total population. Today, critical urban issues arise from the sheer size of the metropolis GCR and from its population density. Traffic congestion is on the top of these issues. This research focuses on the significant role that hubs (Multi Modal Platforms) can play in enhancing the GCR transportation infrastructure. Ramses square area in Cairo is selected to demonstrate a systematic solution to solve the problems resulted from the interference of multi uses activities and transportation modes in central areas of capital cities. Keyword: Greater Cairo Region (GCR); Hubs; Urban Dynamics; Transportation  eISSN 2514-751X © 2018.

Abstract:

The accelerated urbanization in the last decade and population growth in developing countries in the Middle East and North Africa (MENA) region have increased the count of humans exposed to air pollution. This work aims to provide an insight into air quality in the Greater Cairo (GC) area which is one of the largest megacities in the MENA region and is classified as its most polluted city according to the reports of the World Health Organization (WHO). Exploratory data analysis and cluster analysis were used to assess the pollutants data and meteorological data to understand the impacts of weather factors on air quality in GC. According to the results, GC suffers from particle matter of 10 micrometres or less (PM10) pollutants. The annual averages ranged from 97 ± 10 to 203 ± 42 μg/m3. Though short-term exposure to gaseous pollutants did not exceed the limits, the long-term exposures exceeded those in some congested traffic areas. The annual averages ranged from 20 ± 5 to 63 ± 24 μg/m3 for Nitrogen dioxide (NO2) and from 9 ± 3 to 21 ± 5 μg/m3 for sulphur dioxide (SO2). Also, the terrain affects the spatial variation of pollutants observation. There is a negative correlation between the monitoring site elevation and the pollutant concentration.

Abstract:

Transit-Oriented Development (TOD) land use theories have been applied in multiple countries both developed and developing areas of the globe. It has proven its strength in maintaining a more sustainable approach in both urban development and lifestyle. The greater Cairo Region is witnessing huge transportation projects such as Electric Elevated Train that connect old Cairo with the new Capital City in the Eastern desert of Egypt. The New electric Train line is foreseen as a major clean transportation for number of important areas in greater Cairo, nevertheless it lacks more broader urban planning vision to use the transit main spots as a potential of applying a land use planning approach to maximize the urban potentials of these sites. This paper is providing a land-uses planning approach to maximize the land uses around these transits stops by providing the theory of transit-oriented development and propose the suitable solution that TOD offer to create more comprehensive sustainable urban oasis. The paper theorizes TOD land use planning, and what suitable development could be provided for such spots. Analysis of the locations of main train stops are provided, recommendation for one stop TOD development as a replica for other main stops to create more sustainable urban oases in the eastern desert of Cairo New Capital.

Abstract:

The last few decades, Egypt drawn into a dramatic socio-economic change that causes a relative change in adopted development patterns. Different typologies of new residential districts have turned from globalized westernized world into Egyptian context. Planners and authority thought that changing adopted development patterns from traditional to modern neighborhood could provide solutions for old town's problems. On the other hand, different scholars have emphasized that traditional compact, mixed use, high-density urban forms are important for reaching sustainability goals in term of environmental, economic and social advantages. Based on a comparison of the sustainability of three case studies Shubra, Heliopolis, and new Cairo city; this research examine analyze the sustainability of New Egyptian Settlements. The analysis depends on observation and spatial analysis to investigate the variations of performances between the three case studies in terms of urban, social, environmental, and economic sustainability indicators. The research aims to assess the sustainability of moving from traditional to modern urban form in GCR' new towns and to extract development criteria and lessons learned from traditional urban form to enhance the sustainability of modern settlements. The research concluded that both traditional early developed settlements like Shubra and new planned settlements like new Cairo recorded low performance in sustainability issues, each one in its own way; and that early planned settlements like Heliopolis recorded moderate performance in sustainability issues, this paves the way for criteria to prepare new plans of new settlements and provide intensification repair tools to fix existing new settlements.

Abstract:

In recent decades, housing has come to be seen as more than just a physical structure, but a setting where residents can build long-term social connections. The problem is particularly persistent in residential blocks that lack integration with the unbuilt environment and intermediate spaces, negatively affecting the quality of life for both individuals and the community. This study seeks to explore the influence of tactical-sim and community involvement in the formation of decent neighborhoods, with a particular emphasis on addressing housing inadequacy and inaccessibility in the case of Cairo, Egypt. A methodology based on architectural, urban and psychological indicators was used to analyze this problem in several typologies across the Greater Cairo Region. The findings of the study highlighted several critical issues with the national housing policies and planning, including social segregation and planning injustice; attributable to inadequate integration of semi-public and open spaces or green areas with housing, insufficient community involvement in the planning process and lastly, the tendency to standardize the spatial layout of residential blocks while restricting opportunities for the private sector only.

Abstract:

In the Middle East and North Africa (MENA) region, studies focused on the relationship between urban planning practice and climatology are still lacking, despite the fact that the latter has nearly three decades of literature in the region and the former has much more. However, such an unfounded relationship that would consider urban sustainability measures is a serious challenge, especially considering the effects of climate change. The Greater Cairo Region (GCR) has recently witnessed numerous serious urban vehicular network re-development, leaving the city less green and in need of strategically re-thinking the plan regarding, and the role of, green infrastructure. Therefore, this study focuses on approaches to the optimization of the urban green infrastructure, in order to reduce solar irradiance in the city and, thus, its effects on the urban climatology. This is carried out by studying one of the East Cairo neighborhoods, named El-Nozha district, as a representative case of the most impacted neighborhoods. In an attempt to quantify these effects, using parametric simulation, the Air Temperature (Ta), Mean Radiant Temperature (Tmrt), Relative Humidity (RH), and Physiological Equivalent Temperature (PET) parameters were calculated before and after introducing urban trees, acting as green infrastructure types that mitigate climate change and the Urban Heat Island (UHI) effect. Our results indicate that an optimized percentage, spacing, location, and arrangement of urban tree canopies can reduce the irradiance flux at the ground surface, having positive implications in terms of mitigating the urban heat island effect.

Abstract:

Cities in the Global South are experiencing profound demographic shifts, rapid economic growth, and unchecked urban sprawl, resulting in significant transformations in peri-urban landscapes. This paper focuses on assessing the impacts of chaotic urban expansion in the peri-urban areas (PUAs) of Greater Cairo (GC), serving as a notable case study in the Global South. By analyzing satellite imagery from 2001, 2011, and 2021, this study examines changes in land use/cover (LUC) within GC’s PUAs. Employing five landscape metrics—Landscape Expansion Index (LEI), Percentage of Landscape (PLAND), Fractal Dimension Index (FDI), Mean Patch Size (MPS), and Largest Patch index (LPI)—the research elucidates the adverse effects of unplanned urban expansion in GC’s PUAs. The analysis reveals a substantial loss of over 51 thousand hectares of arable land, raising concerns about food security in the region. Notably, the LEI identifies edge expansion as the predominant urban expansion pattern, while PLAND, FDI, and LPI metrics underscore landscape fragmentation within the peri-urban landscape. These findings have significant implications for authorities and researchers engaged in sustainable development efforts in PUAs. This study lays a crucial foundation for the formulation of successful management strategies to mitigate the adverse consequences of unplanned urban expansion in the PUAs of GC and similar regions worldwide.

Abstract:

Uncontrolled on-ramp merging section is considered as a bottleneck at several locations on urban expressways in Greater Cairo Region (GCR). This study aims to evaluate the impacts of applying ramp metering control on the traffic performance at three critical on-ramp sites on the 6th of October corridor using VISSIM. The simulation models were calibrated using the traffic data collected during peak period. Two different control strategies were tested; fixed-time ramp metering and actuated control for both mainline and on-ramp traffic, and compared to “no control” using average speed, average vehicle delay and on-ramp queue length as performance measures. The results indicated that fixed-time ramp metering could improve the overall traffic performance at merging sections by increasing the speed up to 100% and reducing the average vehicle delay up to 50%. However, fixed-time ramp metering control results in on-ramp queue spillback onto adjacent roads at some sites due to insufficient ramp storage length and huge on-ramp volumes. In this case, the actuated control strategy showed significant improvements on traffic performance at both the mainline and on-ramp, in addition to the whole system by increasing the speed by 25%, reducing the average delay by 11%, and reducing the queue length by 35%.

Abstract:

Algal blooms at the major water treatment plants in Egypt have been reported since 2006. While previous studies focused on algal types and their correlation with disinfection by-products, correlation between raw water quality and algal blooms were not explored. Therefore, a survey of Nile water quality parameters at a major water intake in the Greater Cairo Urban Region was conducted from December 2011 to November 2012. Bench-scale experiments were conducted to evaluate the effectiveness of the conventional chloride/alum treatment compared with combined Cl/permanganate pre-oxidation with Al and Fe coagulants during the outbreak period. Addition of permanganate (0.5 mg/L) significantly reduced the chlorine demand from 5.5 to 2.7 mg/L. The applied alum coagulant dose was slightly reduced while residual Al was reduced by 27% and the algal count by 50% in the final treated waters. Applying ferric chloride and ferric sulfate as coagulants to waters treated with the combined pre-oxidation procedure effectively reduced algal count by 60% and better the total organic carbon reduction and residual aluminum in the treated water. Multivariate statistical analysis was used to identify the relationship between water quality parameters and occurrence of algae and to explain the impact of coagulants on the final water quality.

Abstract:

Traffic congestions is one of the main problems for many cities especially in newly urbanizing countries worldwide. The issue of traffic congestions has major impact not only on the planning of the city, but also on many aspects such as residence overall well-being. Governments often try to address this issue through a number of initiatives, most important of which is promoting public transport in order to reduce the dependency on private cars in the city. This research analyzed state-led public transportation initiatives impact on addressing traffic congestion in developing countries through a case study of the Greater Cairo Region in Egypt. The research specifically focused on two state-led public transportation programs, namely the Great Cairo Transport Authority (CTA) program to improve the existing public transport services in GCR and the GCR underground metro program during the 1990s to early 2010s. The research found that although these programs were successful in limiting the increase of privately owned cars and taxies in GCR, they did not decrease traffic congestions due to a number of issues including malpractice, political and administrative corruption, and rapid population growth and increased population densities that almost doubled in the period from early 1990s to early 2010s.

Abstract:

Regarding the sharp growth rate of ICT (information and communication technology)—based mobility services like ridesourcing, it is essential to investigate the impact of these new mobility services on the transport mode choices, particularly on active mobility modes like cycling. This impact is more important in the MENA context (the Middle East and North Africa), where cycling does not constitute the main mobility mode in the modal split of most MENA cities. This paper studies the relationship between the regular use of ICT-based mobility services like ridesourcing and the tendency to cycle to near destinations. This paper contains the analysis of 4431 interviews in two large cities of the MENA region (Cairo and Tehran). This research uses logistic regression to analyze and compare the odds of cycling among regular and non-regular users of ridesourcing by considering the socio-economic, land use, and perception variables. The findings indicate that the odds of cycling among the regular users of ridesourcing are 2.30 and 1.94 times greater than these odds among non-regular ridesourcing users in Tehran and Cairo, respectively. Therefore, the regular users of ridesourcing are more likely to cycle to their near destinations than non-regular ridesourcing users in these cities.
