Over the last two decades, solid waste management in the Middle East–North Africa (MENA) region has been one of the major challenges due to increasing solid waste quantities and poor waste management practices. With the tremendously increasing amounts of organic waste, MENA countries are under great pressure and are facing the threats of acute air pollution, contamination of water bodies and climate change. As a result, these countries are adopting different methods to cope with this rising challenge of waste management, including composting. This review reports on the different MENA countries’ organic waste quantities, disposal methods, organic waste management practices and challenges, along with the potential use and demand of compost, where information is available. The reported data are from 2009 to 2021, with the bulk of the papers being from 2014 and onwards. The total amount of municipal waste collected in the 21 countries ranged from 0.56 million tons in Mauritania to 90 million tons in Egypt, with an average of 16.42 million tons, equivalent to 1.08 kg per capita waste generation per day. Around 55% of this material is biogenous. Many treatments and repurposing methods of this material are adopted in the MENA region, mainly through composting, as it presents one of the most sustainable solutions that lead to immediate climate change mitigation. This article also presents the biotic and abiotic stressors faced by this region, which in turn affect the successful implementation of composting solutions, and proposes some solutions based on different studies conducted.

<p>The region of the Middle East and North Africa (MENA region) encompasses countries of the eastern Mediterranean, the Middle East, and North Africa, from Morocco in the West to the Islamic Republic of Iran in the East and from the Syrian Arab Republic in the North to the Republic of Yemen in the South. It is home to some 500 million inhabitants and is characterized by widely varied political and economic settings and a rich cultural heritage. Stark environmental gradients, as well as significant differences in the provision of ecosystem services, both East to West and South to North, are typical for the MENA Region.</p><p>Climate changes in the Mediterranean Basin, in general, and in the MENA countries, in particular, currently exceed global mean values significantly. Numerical model results indicate that this trend will continue in the near future and imply that the number of extreme summer temperatures and heatwaves may increase significantly over the coming decades. At the same time, a decrease in precipitation and a significantly longer dry season for most MENA countries than at present are anticipated. This leads to a significantly increased demand for water and energy. In addition, other factors further exacerbate these demands in the MENA, including the general economic development, extreme population growth and increasing urbanization, changes in lifestyle, shifting consumption patterns, inefficiencies in the use of resources that result from technical and managerial inadequacies and energy and water subsidies in several countries of the region to name but a few.</p><p>The impacts of climate change will be particularly severe in urban settings and large cities of the Mediterranean Basin and the MENA region. Cities will see an enhanced heat accumulation compared to the surrounding rural land due to heat-build-up in buildings, transportation infrastructure, and enhanced human activities. Reduced ventilation within cities exacerbates the warming, particularly during summer heatwaves. Consequently, additional, energy-intensive space cooling will be needed in order to maintain acceptable indoor conditions. With regard to water scarcity, the aforementioned decreases in precipitation will reduce available drinking water for city inhabitants and green spaces. This requires the provision of unconventional water sources, e.g., through desalination, which requires significant quantities of energy. Overall, climate change will exacerbate resource demand for water and energy, in general, and in urban settings, in particular.</p><p>However, the provision of water and energy are interrelated. In order to maintain water and energy security in the MENA region, these issues need therefore be considered holistically in the framework of the Water-Energy-Nexus (WEN).</p><p>The present paper aims to elucidate some of the interrelationships between water and energy resources and their provision and will briefly outline a few of the possible mitigation/adaptation options/strategies to reduce adverse impacts of climate change on the MENA region and its inhabitants.</p>

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.

The waste management practices in primary healthcare centres of Iran were investigated in the present study. A total of 120 primary healthcare centres located across the country were selected using the cluster sampling method and the current situation of healthcare waste management was determined through field investigation. The quantities of solid waste and wastewater generation per outpatient were found to be 60 g outpatient—1 day—1 and 26 L outpatient—1 day— 1, respectively. In all of the facilities, sharp objects were separated almost completely, but separation of other types of hazardous healthcare solid waste was only done in 25% of the centres. The separated hazardous solid waste materials were treated by incineration, temporary incineration and open burning methods in 32.5, 8.3 and 42.5% of the healthcare centres, respectively. In 16.7% of the centres the hazardous solid wastes were disposed of without any treatment. These results indicate that the management of waste materials in primary healthcare centres in Iran faced some problems. Staff training and awareness, separation of healthcare solid waste, establishment of the autoclave method for healthcare solid waste treatment and construction of septic tanks and disinfection units in the centres that were without access to a sewer system are the major measures that are suggested for improvement of the waste management practices.

The Middle East and North Africa (MENA) region suffers a drastic change from a traditional diet to an industrialized diet. This has led to an unparalleled increase in the prevalence of chronic diseases. This review discusses the role of nutritional genomics, or the dietary signature, in these dietary and disease changes in the MENA. The diet-genetics-disease relation is discussed in detail. Selected disease categories in the MENA are discussed starting with a review of their epidemiology in the different MENA countries, followed by an examination of the known genetic factors that have been reported in the disease discussed, whether inside or outside the MENA. Several diet-genetics-disease relationships in the MENA may be contributing to the increased prevalence of civilization disorders of metabolism and micronutrient deficiencies. Future research in the field of nutritional genomics in the MENA is needed to better define these relationships.

Rapid urbanization and uncontrolled population growth in the city of Akure create a huge generation of municipal solid waste (MSW) and waste management authority has not been able to manage it properly. This has led to inefficient waste collection methods, insufficient coverage of the collection system and improper disposal of solid waste. This paper investigated municipal solid waste management practices in Akure, Ondo State, Nigeria. Simple random sampling was used in selecting 392 respondents within the eight districts in the study area. Information was collected on socio-economic characteristics of the respondents; nature and compositions of municipal solid waste and solid waste management practices in the study area. The study showed that female respondents (58.2%) were more than male (41.8%) in the study area. Also, a larger proportion of the respondents earned above N40,000 per month. More than one-third of the respondents (37.8%) created squander from vegetable and food remains, next to this were plastic (19.1%), paper (8.2%) and metal waste (6.6%). Further findings showed that the majority of the respondents (66%) do not segregate waste before disposal while the wastebasket was commonly preferred to collect waste due to its affordability. The study concluded that despite the establishment of waste management authority, most of the wastes collected was not sorted before disposal while the majority of the respondents preferred to burn their waste. The study recommended that government and non-governmental organizations should pay much attention to the issue of waste management in the area as waste was not properly managed.

Background. Studies on environmental performance/quality and economic growth show inconclusive results. Objective. The aim of the present study is to assess the non-linear relationship between environmental performance and economic growth in the Middle East and North Africa (MENA) region from 2002–2018. Methods. A sample of fourteen (14) MENA countries was used in the present analysis. However, due to important differences between countries in this region, the whole sample was divided into two sub-samples; nine Middle Eastern countries (MEAS) and five North African countries (NAF). We performed the panel smooth transition regression model as an econometric approach. Discussion. Empirical results indicate a threshold effect in the environmental performance and economic growth relationship. The threshold value differs from one group of countries to another. More specifically, we found that the impact of environmental performance and economic growth is positive and significant only if a certain threshold level has been attained. Until then, the effect remains negative. Conclusions. The findings of the present study are of great importance for policymakers since they determine the optimal level of environmental performance required to act positively on the level of economic growth. MENA countries should seek to improve their environmental performance index in order to grow output. Competing Interests. The authors declare no competing financial interests.
