Using Data

The duration and intensity of future heat waves are analyzed for 53 cities in the Middle East and the North Africa (MENA) region for the 21st century under two different scenarios (RCP4.5 and RCP8.5). A consistent approach is carried out using data from 13 Regional models within the framework of the Coordinated Regional Climate Downscaling Experiment (CORDEX). By the end of the century, 80% of the most populated MENA cities are expected to be at least 50% of the days under heat wave conditions during the warm season. In addition, the mean and maximum intensity of the heat waves will also increase. Changes in the duration and intensity of heat waves have shown to be negatively correlated. Therefore, the vulnerability of the MENA cities to future heat waves was determined using a cumulative index (CI) that takes into account both duration and intensity. This CI indicates that Middle East and the eastern part of Africa will suffer the most unfavorable temperature conditions in the future. Assuming no intervention trough adaptation/mitigation strategies, these results, together with the particular properties of the MENA region, such as aridity or lack of precipitation, make it likely that the area will be affected by disease or famine.

Impacts Of Climate Change

The present paper aims to elucidate impacts of climate change on the availability and security of water and energy in the Middle East and North Africa region (MENA region; including the Eastern Mediterranean) in the context of the water–energy nexus. It largely builds on existing knowledge and understanding and aims to present a review of existing information on this topic. The region is particularly challenged by a number of factors, including the large variability of bio-geographical characteristics, extreme population growth over the last few decades, and substantial societal and economical transitions, as well as armed conflicts in some of the countries in the region. Anticipated changes in climate conditions will exacerbate the challenges regarding water and energy security in the region. Major impacts of climate change include a significant increase in summer temperatures, which will lead to a growing number of heat waves, primarily in urban structures. A general decrease in precipitation in many of the MENA countries is foreseen, resulting in enhanced droughts and a growing number of dry spells. In addressing energy and water scarcities and their mutual interrelationships, an integrated water–energy nexus concept offers promising prospects to improve environmental, climate, human, and political security. However, only very few countries in the MENA region have presently implemented such a concept. Mitigation and adaptation strategies addressing water and energy scarcity include enhanced efficiency of resource use, integrated technology assessments regarding electricity generation, and a stronger reliance on renewable/solar technologies. While looking at the MENA region as a whole, some emphasis will be given to Cyprus and the Eastern Mediterranean.

This study investigates the historical climatology and future projected change of atmospheric rivers (ARs) and precipitation for the Middle East and North Africa (MENA) region. We use a suite of models from the Coupled Model Intercomparison Project Phase 5 (CMIP5, historical and RCP8.5 scenarios) and other observations to estimate AR frequency and mean daily precipitation. Despite its arid-to-semi-arid climate, parts of the MENA region experience strong ARs, which contribute a large fraction of the annual precipitation, such as in the mountainous areas of Turkey and Iran. This study shows that by the end of this century, AR frequency is projected to increase (~20–40%) for the North Africa and Mediterranean areas (including any region with higher latitudes than 35 N). However, for these regions, mean daily precipitation (i.e., regardless of the presence of ARs) is projected to decrease (~15–30%). For the rest of the MENA region, including the Arabian Peninsula and the Horn of Africa, minor changes in AR frequency (±10%) are expected, yet mean precipitation is projected to increase (~50%) for these regions. Overall, the projected sign of change in AR frequency is opposite to the projected sign of change in mean daily precipitation for most areas within the MENA region.

Air pollution is reported as one of the most severe environmental problems in the Middle East and North Africa (MENA) region. Remotely sensed data from newly available TROPOMI - TROPOspheric Monitoring Instrument on board Sentinel-5 Precursor, shows an annual mean of high-resolution maps of selected air quality indicators (NO2, CO, O3, and UVAI) of the MENA countries for the first time. The correlation analysis among the aforementioned indicators show the coherency of the air pollutants in urban areas. Multi-year data from the Aerosol Robotic Network (AERONET) stations from nine MENA countries are utilized here to study the aerosol optical depth (AOD) and Ångström exponent (AE) with other available observations. Additionally, a total of 65 different machine learning models of four categories, namely: linear regression, ensemble, decision tree, and deep neural network (DNN), were built from multiple data sources (MODIS, MISR, OMI, and MERRA-2) to predict the best usable AOD product as compared to AERONET data. DNN validates well against AERONET data and proves to be the best model to generate optimized aerosol products when the ground observations are insufficient. This approach can improve the knowledge of air pollutant variability and intensity in the MENA region for decision makers to operate proper mitigation strategies.

Abstract This study investigates future changes of temperature, precipitation, and associated extreme events in the MENA region using Regional Climate Model ALADIN-Climate over the CORDEX-MENA domain. Model capabilities to reproduce key observed regional climate features are first assessed, including heat waves, drought and high precipitation extremes. Projected changes indicate the intensification of heat waves number, duration and magnitude, and contrasted precipitation changes. A drying is projected in the north-west and moistening in the north-east along the Mediterranean side of the region. Projected regional warming is found at the rate of about 0.2 °C/decade to 0.5 °C/decade over land depending on the scenario. Drought is expected to increase in the northern half of the region independently from the index used, but with a higher rate in the case of the index accounting for both the effect of precipitation and temperature changes. ALADIN-Climate results corroborate previous studies projecting the MENA region to host global hot spots for drought in the late twenty-first century.

In recent years, North African queer cinema has become increasingly visible both within and beyond Arabo-Orientale spaces. A number of critical factors have contributed to a global awareness of queer identities in contemporary Maghrebi cinema, including the dissemination of films through social media outlets and during international film festivals. Such tout contemporain representations of queer sexuality characterize a robust wave of films in the Middle East and North Africa (MENA) region, inciting a new discourse on the condition of the marginalized traveler struggling to locate new forms of self and being—both at home and abroad.

The Impact

Abstract Background Coronavirus disease (COVID-19) pandemic has affected health and lifestyle behaviors of people globally. This project aims to identify the impact of COVID-19 on lifestyle behavior of individuals in the Middle East and North Africa (MENA) region during confinement. Methods We conducted an online survey in 17 countries (Egypt, Jordan, United Arab Emirates, Kuwait, Bahrain, Saudi Arabia, Oman, Qatar, Yemen, Syria, Palestine, Algeria, Morocco, Libya, Tunisia, Iraq, and Sudan) from the MENA region on August and September 2020. The questionnaire included self-reported information on lifestyle behaviors, including physical activity, eating habits, smoking, watching television, social media use and sleep before and during the pandemic. Logistic regression was performed to analyze the impact of COVID-19 on lifestyle behaviors. Results A total of 5896 participants were included in the final analysis and 62.8% were females. The BMI of the participants was 25.4 ± 5.8 kg/m2. Around 38.4% of the participants stopped practicing any physical activities during the confinement (P < 0.001), and 57.1% reported spending more than 2 h on social media (P < 0.001). There were no significant changes in smoking habits. Also, 30.9% reported an improvement in their eating habits compared with 24.8% reported worsening of their eating habits. Fast-food consumption decreased significantly in 48.8% of the study population. This direct/indirect exposure to COVID-19 was associated with an increased consumption of carbohydrates (OR = 1.09; 95% CI = 1.02–1.17; P = 0.01), egg (OR = 1.08; 95% CI = 1.02–1.16; P = 0.01), sugar (OR = 1.09; 95% CI = 1.02–1.16; P = 0.02), meat, and poultry (OR = 1.13; 95% CI = 1.06–1.20; P < 0.01). There was also associated increase in hours spent on watching television (OR = 1.07; 95% CI = 1.02–1.12; P < 0.01) and social media (OR = 1.09; 95% CI = 1.01–1.18; P = 0.03). However, our results showed a reduction in sleeping hours among those exposed to COVID-19 infection (OR = 0.85; 95% CI = 0.77–0.94; P < 0.01). Conclusions The COVID-19 pandemic was associated with an increase in food consumption and sedentary life. Being exposed to COVID-19 by direct infection or through an infected household is a significant predictor of amplifying these changes. Public health interventions are needed to address healthy lifestyle behaviors during and after the COVID-19 pandemic.

Previous studies have contrasted the political party systems in the Middle East and North Africa (MENA) with those in more democratic countries, raising three important points: (1) the religious–secular dimension, rather than the economic or social left–right, explains the underlying political party competition; (2) left-wing politics is relatively weaker than right-wing politics; and (3) parties that are traditionally known as rightist take left-leaning positions on numerous issue dimensions, and vice versa. Even though this particular literature on party politics in the MENA has greatly improved our understanding of political dynamics in the region, these studies have either lacked quantitative evidence to support these points or their evidence was limited to single-country cases. This study aims to address this issue by analyzing original expert survey data of the ideological positions of political parties in the MENA region. Results show that in addition to the religious–secular dimension, the economic left–right divide and the pace of political reforms are highly important dimensions. The study also provides numerous examples showing that the policy stances of leftist and rightist parties are significantly reversed when MENA countries are compared with more developed democracies.

Abstract This article aims at presenting ISIS expansion in North Africa in the first quarter of 2016, with its subsequent implication in the wider framework of Jihadist proliferation worldwide. It can be argued that, while losing real estate in the Middle East, ISIS has started a permanent search for extra-cellular matrices or an ongoing process of de- and reterritorialization. The allegiance and support pledged by other African-based terrorist groups or organizations such as Boko Haram, al-I’tisam of the Koran and Sunnah in Sudan, al-Huda Battalion in Maghreb of Islam, The Soldiers of the Caliphate, al-Ghurabaa, Djamaat Houmat ad-Da’wa as-Salafiya and al-Ansar Battalion in Algeria, Islamic Youth Shura Council, Islamic State Libya (Darnah), in Libya, Jamaat Ansar Bait al-Maqdis, Jund al-Khilafah and Mujahideen Shura Council in the Environs of Jerusalem in Egypt, Okba Ibn Nafaa Battalion, Mujahideen of Tunisia of Kairouan and Jund al-Khilafah in Tunisia and al-Shabaab Jubba Region Cell Bashir Abu Numan in Somalia is an alarming hypothesis of Jihadism reaching “the threshold of inevitability”- syntagm existent in the network theories of David Singh Grewal- turning a whole region, continent of even world into what Nassim Nicholas Taleb would call Extremistan.
