“…In addition, most of the urban peripheries in developing countries suffer from lack of access to basic services and infrastructure [13]. The rapid loss of agricultural eventually threatens the sustainability in these territories [38]. However, very few studies have undertaken on appropriate indicators for assessing SD in the urban periphery [12,[39][40][41].…”

During the last few decades, sustainable development (SD) has increasingly received attention globally. Therefore, international organizations and researchers sought to assess progress towards SD at different territorial levels. However, most of the studies were conducted at the city level and a very small number of studies has conducted at the urban periphery territory. This study aims to fill the current research gap through assessing the progress towards SD in the urban periphery of Greater Cairo (GC) in Egypt between 1996-2017. Eight composite indicators have been employed to assess the progress towards SD in this territory. These composite indicators were constructed based on the 14 individual indicators associated with sustainable development goals. The results showed meaningful progress achieved in the peripheral municipalities of GC, particularly in infrastructure and education indicators, while the economic and environmental indicators have deteriorated, particularly after the civic revolution of 2011. In addition, the study found a development gap between the urban periphery and the main urban agglomeration in GC, particularly in the infrastructure aspect. These results highlight the deficiencies that exist in the urban periphery of GC which help decision-makers to prepare appropriate policies to improve SD in such territory.

“…While industry and services are the main economic activities in the central areas, agriculture remains the key activity in suburban areas [40]. However, these suburban areas have also witnessed a drastic decrease in its agricultural land since 2011, with almost 9600 ha being converted from agricultural to urban use [31]. The northern and southern portions of the study region are occupied by two main industrial complex zones, Shoubra El-Khiema and Helwan, respectively [26].…”

“…[75] indicated a warming trend of nighttime LST over Greece between 2000 and 2007, while daytime LST exhibited a decreasing trend. In addition to the role of climate variability, the rapid increase in both daytime and nighttime LST over the past two decades might be amplified by the decline in agricultural lands over these areas, which has been evident for agricultural zones in the entire Egyptian territory [31,78,79].

“…[80] demonstrated that although the per capita agricultural land area decreased from 0.48 ha to 0.14 during the 20th century, this decline has been more pronounced in the past two decades, reaching only 0.03 ha in 2016 [79]. This decline is mostly associated with the rapid population increase and accordingly high demand for other competitive land uses, including housing, infrastructure, and recreation [31]. It is well-established that a lack of natural vegetation or a decrease in cropland area can induce a decline in the albedo and accordingly a decrease in latent heat of evapotranspiration, which enhances the growth of SUHI.…”

“…As the main demographic, administrative, and economic urban center in Egypt, Greater Cairo has gained the attention of researchers and scientists, with several investigations focusing on air pollution, e.g., [22,23]; road traffic, e.g., [24,25]; climate variability, e.g., [26]; poverty, e.g., [27]; criminal behavior, e.g., [28]; health conditions, e.g., [29,30]; land use changes, e.g., [31,32]; and urban growth, e.g., [30,[33][34][35]. For Greater Cairo, it is quite challenging to make a comprehensive assessment of SUHI based on ground measurements alone, especially with the large heterogeneity of urban features.…”

This study assesses the spatial and temporal characteristics of nighttime surface urban heat island (SUHI) effects over Greater Cairo: the largest metropolitan area in Africa. This study employed nighttime land surface temperature (LST) data at 1 km resolution from the Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua sensor for the period 2003–2019. We presented a new spatial anomaly algorithm, which allowed to define SUHI using the most anomalous hotspot and cold spot of LST for each time step over Greater Cairo between 2003 and 2019. Results demonstrate that although there is a significant increase in the spatial extent of SUHI over the past two decades, a significant decrease in the mean and maximum intensities of SUHI was noted. Moreover, we examined the dependency between SUHI characteristics and related factors that influence energy and heat fluxes between atmosphere and land in urban environments (e.g., surface albedo, vegetation cover, climate variability, and land cover/use changes). Results demonstrate that the decrease in the intensity of SUHI was mainly guided by a stronger warming in daytime and nighttime LST in the neighborhood of urban localities. This warming was accompanied by a decrease in surface albedo and diurnal temperature range (DTR) over these areas. Results of this study can provide guidance to local urban planners and decision-makers to adopt more effective mitigation strategies to diminish the negative impacts of urban warming on natural and human environments.

Irrigation development is essential for reducing vulnerability to water resource scarcity, food insecurity, and climate change impacts in Egypt. The centralized irrigation development must, however, overcome the challenges of the diversity of smallholders and the pre‐existing, individualistic irrigation management. The purpose of this paper is to examine the farmers' characteristics that influence the design and success of irrigation improvement programmes in the Old Lands of Egypt. The paper investigates this issue from the perspectives of farmers by analysing farm features, agricultural practices, irrigation practices, and satisfaction with water services. The clustering method is applied to create farmer groups within the geographical area of the programme and seek consistent differences that affect the outcome of irrigation improvement. The results show that farmers are less diverse in their agrotechnology and more heterogenous in terms of capacities, livelihood sources, and land tenure structures. The article argues that grouping methods to deploy improved irrigation infrastructure should give more consideration to the farmers' individual features. Programmes intended to replicate such irrigation development or leverage the existing results should address these particularities to create a socially adaptive environment for future irrigation investment in Egypt.
