Impacts Of Climate Change

<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>

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.

Impacts Of Climate Change

The olive tree (Olea europaea L.) is an ancient traditional crop in the Mediterranean Basin. In the Mediterranean region, traditional olive orchards are distinguishable by their prevailing climatic conditions. Olive trees are indeed considered one of the most suitable and best-adapted species to the Mediterranean-type climate. However, new challenges are predicted to arise from climate change, threatening this traditional crop. The Mediterranean Basin is considered a climate change “hotspot,” as future projections hint at considerable warming and drying trends. Changes in olive tree suitability have already been reported over the last few decades. In this context, climate change may become particularly challenging for olive growers. The growing evidence for significant climate change in the upcoming decades urges adaptation measures to be taken. To effectively cope with the projected changes, both short and long-term adaptation strategies must be timely planned by the sector stakeholders and decision-makers to adapt for a warmer and dryer future. The current manuscript is devoted to illustrating the main impacts of climate change on olive tree cultivation in the Mediterranean Basin, by reviewing the most recent studies on this subject. Additionally, an analysis of possible adaptation strategies against the potentially negative impacts of climate change was also performed.

Waste Management Practices

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.

Level Of Risk

After the recent high-impact European outbreaks of Xylella fastidiosa (Xf), a xylem-limited plant pathogenic bacterium native to the Americas, this research aims to rank the risks of potential entry, establishment and spread of Xf in new countries across Europe, the Middle East and North Africa. A novel risk-ranking technique is developed, based on combining entry risk drivers (imported plants, direct flights and ferry connections) with risk factors related to establishment and spread (presence of potential insect vectors, vulnerable economic crops, alternative hosts and climate suitability) of this pathogen. This reveals that western European countries have the highest risk for entry, but that the Mediterranean basin runs the highest risk for establishment and spread of Xf. Lebanon in particular has the highest level of risk for Xf dispersal within its suitable territory. Countries without current outbreaks combining high risks of Xf arrival and establishment are mainly in the Mediterranean basin: Turkey is at the highest level of risk, followed by Greece, Morocco and Tunisia, which are ranked at the high level. The ranking model also confirms the vulnerability, in terms of invasion by Xf, of southern European countries (Italy, Portugal and Spain) in which the pathogen has already been reported. High summer temperatures in these southern countries are likely to be the significant determinant for the overall invasion process, while northern European countries have a high level risk for the arrival of the pathogen, but relatively low summer temperatures may limit establishment and spread of major outbreaks. In general, our study provides a useful approach for mapping and comparing risks of invasive non-native species and emerging pathogens between countries, which could be useful for regional horizon scanning and phytosanitary and biosecurity management.

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.
