The effects of climate change in Syria are considerable. It has adverse effects on the livelihoods of the people as well as its environment. [1] [2] [3] Syria is a developing and non-industrialized country that is located in an arid to semi-arid region. [4] Climate change-induced droughts, water shortages, increasing temperatures and soil degradation affect agriculture especially. [5] Desertification, which has historically been an issue in the region, is accelerating due to climate change. [6] Syria has employed various efforts to address climate change, such as ratifying the Paris Treaty, and submitting its Nationally Determined Contributions (NDCs) with a focus on both adaptation and mitigation measures for the period 2020-2030. [5] While it has contributed to only 0.1% of global emissions, it is highly vulnerable to climate change. [7]
Climate Trace estimate 2023 emissions at 60 million tonnes CO2eq, with the largest sectors being transport and power generation. [8] Syria prepared it first national communication on climate change in 2010. Its total GHG emissions reached 79 million tonnes CO2 eq in 2005. The emissions originated mainly in its energy sector (73%), followed by agriculture sector (18%). These two sectors contributed to more than 90% of all emissions in Syria. [5] Waste has also contributed to emissions, responsible for approximately 5% amongst all sectors from 1994-2005. [9] Waste primarily emitted methane from organic waste in landfills and untreated sewage, though carbon dioxide accounts for the majority of emissions due to the use of fossil fuels in electricity and transport. [9] However the UNFCCC does not insist on military emissions being reported.
There is regional and seasonal variability of droughts in Syria. Autumn seasons have experienced slight increases in rainfall, where critical agricultural seasons such as winter and spring have steadily declined. Additionally, the southwestern portion of the country, near to the Mediterranean, has experienced minor increases in rainfall, while the northwestern portion has steadily declined. [10] Drought risks have been found to be greatest in areas such as Al Qadmus. [11] The Syrian Drought, from 2006-2011, is widely considered one of the worst in the region’s history, and led to widespread agricultural failures, especially in the northeastern portion of the country. Farming and herding communities were deeply affected. [1] The crisis compelled approximately 1.5 million rural Syrians to migrate to cities. [1] While the period of time is consistent with decreasing rainfall data, some studies argue that the Syrian Drought was not a part of long term drying trends attributed to climate change. [2]
There are persistent heatwaves in Syria, particularly since the 2010s. Compound events, which are hot and dry conditions simultaneously, have grown in frequency. These heatwaves have an annual frequency increase of 6.3%. Such extremes are particularly pronounced in northeastern and southwestern Syria. [12] Both frequency and severity of extreme heat events are expected to rise significantly, which is especially true for densely populated areas. The number of people exposed to extreme heat is also projected to increase, as urban populations in Syria are expected to become more vulnerable. [13]
The effect of climate change on Syria is reflected in its water scarcity issues. The Middle East is an arid climate, and climate change exacerbates its existing low precipitation levels and susceptibility to drought. Syria’s overall rainfall has decreased over time between 1991 to 2009, particularly in the northwestern portion of the country in the winter and spring. [10] Reports until 2011 show similar trends, along with increases in average temperatures, which have resulted in extreme droughts. [14] These periods of drought have also grown in frequency and severity from the late 1990s onwards, with some lasting up to 200 days. [6] Notable periods of drought include: 1998-1999, 2007-2008, 1972-1973, 2014, and 2016. [6] [11]
Syria’s water scarcity due to drought is likely to continue intensifying, aligning with IPCC predictions of reduced rainfall in the Mediterranean. [10] Between 2021 to 2050, temperatures could increase by approximately 1.6-2 °C, with precipitation dropping by approximately 11% in the winter and 8% in the spring. [15] [14] By 2070-2099, temperatures could rise by 4 °C, with an overall decrease of 22% in annual precipitation across the region. [15] These reports also predict a 25-27% reduction in runoff, resulting in prolonged dry spells, coastal flooding, and intensified dust storms. [14] The Figeh Spring, a critical water source near Damascus, Syria, is predicted to decrease its peak spring discharge by 20% by 2050, and up to 50% by the end of the century. [15] Reduced recharge due to less snow and higher evapotranspiration could lead to a 9-30% decrease in annual discharge by the century’s end. The decline of Figeh Spring’s water output poses risks for Damascus’ water supply. [15]
Climate change’s influence on drought periods have had effects on Syria’s agricultural systems. [14] Only 10% of Syria’s farmland is irrigated, with its remaining portion relying on rainfall. [16] Declining rainfall, poor irrigation practices, and government neglect of rural areas weakened food security and employment. Wheat production, for example, fell significantly, forcing Syria to import it for the first time. [16] This severe strain on Syria’s agriculture sector is due to climate change-driven drought, resulting in intensified water scarcity. Projected climate changes could further reduce agricultural productivity and increase soil salinity. [14] This is especially true for areas such as the Fertile Crescent, an area crucial for agriculture, where decreased precipitation has resulted in major crop losses. [1] Syria’s unsustainable use of water resources and depleted river levels have long presented risks, with future climate trends likely to worsen groundwater depletion and drive greater reliance on rainfall. [14]
Climate change has caused considerable damage to the livelihood of Syrian farmers. Droughts and desertification have caused a massive exodus of around 1.5 million people from rural agricultural communities to urban environments. [14] These droughts, combined with government mismanagement, caused roughly 800,000 farmers to lose their livelihoods. [14] The economic impacts of climate change on Syria are also projected to be devastating, with predictions stating that any given Syrian household, rural or urban, stands to lose 1.6 to 2.8 percent of their welfare annually due to climate change. [17] The poorest groups of farmers have the least amount of resources to recover from droughts. Therefore, they are disproportionately affected by water shortages. [17] Moreover, they take longer to recover financially. [3]
The drought in Syria from 2006-2010 decreased agricultural productivity and food access, as well as water scarcity. Scarcity of clean water, especially after Syria's major drought, has increased the risk of waterborne disease. Limited sanitation infrastructure has exacerbated health vulnerabilities, along with displacement and overcrowding which has increased disease transmission. [18] Syria’s climate-related impacts may worsen nutrition due to food insecurity related to agricultural productivity losses. The presence of waterborne diseases may also increase, with risks of malaria and vector-borne diseases caused by shifting climates and increases in drought-resilient rodent populations. [14] The World Health Organization has called for increased support in disease surveillance, mental health services, and emergency preparedness. WHO advocates for targeted aid to address these health impacts. [18]
There are also health damages associated with Syria's electricity generation system. Heavy fuel oil power plants, due to high sulfur content, generate significant health-related costs through pollutants that lead to respiratory and cardiovascular issues. The costs of these health issues vary significantly depending on the population density around the power plants. Facilities near densely populated areas, like Damascus, result in higher health costs due to more people being exposed to pollutants. [19]
The major drought in early 2000s affected agricultural production. Economic factors have driven force of unrest, along with their failure to address a rising humanitarian crisis. [2] [20] The discontent in rural areas went back several years before the major drought. Syrian media outlets were also a factor, as they excluded coverage of the drought and its economic and political consequences. [20] More comprehensively, climate change, poor water management, and lack of governmental support were all major elements that eventually led to the Syrian civil war. [20]
Syria has moderate fossil fuel reserves, including oil and natural gas, though both contribute to emissions and therefore climate change. There have been significant efforts to expand natural gas for electricity production. Fossil fuels in the past and in modern day dominate energy sources, though hydropower is also a dominant source in Syria’s energy profile. Renewable energy has been increasingly considered for long-term sustainability. [21] The Syrian Civil War has also caused considerable damage to the country's infrastructure in areas such as healthcare and residential, which has lowered the ability of the country to respond to the negative effects of climate change. [22]
Syria's poor electricity infrastructure lacks capacity to endure extreme weather events such as heat waves, which are projected to worsen. Syria’s demand for cooling systems has also increased with urbanization, population growth, and rising temperatures. [23]
Syria has high potential for utilization of solar energy, with average irradiance levels about 5 kWh/m²/day. Solar water heating systems have been in use, and there have also been plans to expand photovoltaic systems for both residential and rural applications. The Wind Atlas for Syria shows promising wing speeds in central, southern, and coastal areas. With these speeds, Syria has the potential to produce 85,000 MW of wind energy. Biomass resources, including animal and agricultural waste, are sufficient to produce approximately 357 million m³ of biogas annually. While hydropower energy sources are significant, it is ongoingly limited by low precipitation and reliance on international rivers. [21]
Syria has a number of international climate policies which it is involved in, with some being through the UNFCCC. This includes the 2010 Greenhouse Gas Inventory. [14]
The country's internal environmental legislation has been known to be difficult to enforce, especially due to the unrest caused by the Syrian Civil war. [24] Deliberate environmental attacks have proved hard to stop or are hard to enforce given the well discussed vague and high thresholds of both Syrian environmental law as well as international humanitarian and environmental laws. [24]
In an attempt to improve the country's food production and irrigating parts of the Middle Eastern Steppe, the Syrian government has instituted several policies centered around expanding irrigation, damming and the construction of reservoirs. The findings on the sustainability of these projects was inconclusive, however, it was found that irrigation of certain areas led to increased soil salinization. [25]
Fighting desertification and deforestation has also been a focus of the Syrian government as well as forestry NGOs operating in the region. [26] Only 3% of Syria's land area is forest, and many communities living in those areas use the forest as a resource, but come into conflict with farmers illegally grazing their livestock in and around the forests. [26]
Climate change is an urgent and significant issue affecting Japan. In recent years, the country has observed notable changes in its climate patterns, with rising temperatures serving as a prominent indicator of this phenomenon. As an archipelago situated in northeastern Asia, Japan is particularly vulnerable to the impacts of climate change due to its diverse geography and exposure to various weather systems. The nation experiences a broad range of climates, spanning from the frigid winters of Hokkaido to the subtropical climates of Okinawa. Changes in temperature patterns have the potential to disrupt ecosystems, impact agricultural productivity, modify water resources, and pose significant challenges to infrastructure and human settlements.
Climate change has a broad range of impacts in Jordan, including the already scarce water resources. The temperature increases adversely affect an already warmer and arid climate, and are accompanied by droughts, extreme temperatures, landslides and floods. Water resources in Jordan are scarce. Besides the rapid population growth, the impacts of climate change are likely to further exacerbate the problem. Temperatures will increase and the total annual precipitation is likely to decrease, however with a fair share of uncertainty. Hence, existing and new activities with the objective to minimize the gap between water supply and demand contribute to adapt Jordan to tomorrow's climate. This might be accompanied by activities improving Jordan's capacity to monitor and project meteorological and hydrological data and assess its own vulnerability to climate change.
The main causes of water scarcity in Africa are physical and economic water scarcity, rapid population growth, and the effects of climate change on the water cycle. Water scarcity is the lack of fresh water resources to meet the standard water demand. The rainfall in sub-Saharan Africa is highly seasonal and unevenly distributed, leading to frequent floods and droughts.
There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security. Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. These effects of climate change can also increase the risk of several regions suffering simultaneous crop failures. Currently this risk is regarded as rare but if these simultaneous crop failures did happen they would have significant consequences for the global food supply. Many pests and plant diseases are also expected to either become more prevalent or to spread to new regions. The world's livestock are also expected to be affected by many of the same issues, from greater heat stress to animal feed shortfalls and the spread of parasites and vector-borne diseases.
Climate change is predicted to have significant effects on the living conditions in Argentina. The climate of Argentina is changing with regards to precipitation patterns and temperatures. The highest increase in the precipitation has occurred in the eastern parts of the country. The increase in precipitation has led to more variability in precipitation from year to year in the northern parts of the country, with a higher risk of prolonged droughts, limiting agriculture in these regions.
Climate change in Arizona encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Arizona.
In Iraq, climate change has led to environmental impacts such as increasing temperatures, decreasing precipitation, land degradation, and water scarcity. Climate change poses numerous risks to human health, livelihoods, political stability, and the sustainable development of the nation. The combination of ecological factors, conflict, weak governance, and an impeded capacity to mitigate climate change, has made Iraq uniquely at risk to the negative effects of climate change, with the UN ranking them the 5th most vulnerable country to climate change. Rising temperatures, intensified droughts, declining precipitation, desertification, salinization, and the increasing prevalence of dust storms are challenges Iraq faces due in to the negative impacts of climate change. National and regional political instability and conflict have made it difficult to mitigate the effects of climate change, address transnational water management, and develop sustainably. Climate change has negatively impacted Iraq's population through loss of economic opportunity, food insecurity, water scarcity, and displacement.
Climate change in Algeria has wide-reaching effects on the country. Algeria was not a significant contributor to climate change, but, like other countries in the Middle East and North Africa (MENA) region, is expected to be among the most affected by climate change impacts. Because a large part of the country is in already hot and arid geographies, including part of the Sahara, already strong heat and water resource access challenges are expected to get worse. As early as 2014, scientists were attributing extreme heat waves to climate change in Algeria. Algeria was ranked 46th of countries in the 2020 Climate Change Performance Index.
Climate change in Tanzania is affecting the natural environment and residents of Tanzania. Temperatures in Tanzania are rising with a higher likelihood of intense rainfall events and of dry spells.
Climate change is expected to significantly impact Morocco on multiple dimensions, similar to other countries in the Middle East and North Africa region. As a coastal country with hot and arid climates, environmental impacts from climate change are likely to be wide and varied. Analysis of these environmental changes on the economy of Morocco are expected to create challenges at all levels of the economy. The main effects will be felt in the agricultural systems and fisheries which employ half of the population, and account for 14% of GDP. In addition, because 60% of the population and most of the industrial activity are on the coast, sea level rise is a major threat to key economic forces. Morocco’s average temperatures have increased by 0.2 °C per decade since the 1960s. Morocco is particularly susceptible to heat waves, droughts and floods.
Climate change is posing an increasing threat to global socioeconomic development and environmental sustainability. Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. Climate change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.
Iran is among the most vulnerable countries to climate change in the Middle East and North Africa (MENA). Iran contributes to about 1.8% of global greenhouse gas emissions (GHG), and is ranked 8th in greenhouse gas emissions (GHG) world wide and is ranked first in the MENA region due to its reliance on oil and natural gas. Climate change has led to reduced precipitation as well as increased temperatures, with Iran holding the hottest temperature recorded in Asia.
Climate change and agriculture are complexly related processes. In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. While agriculture plays a role in propelling climate change, it is also affected by the direct and secondary consequences of climate change. USDA research indicates that these climatic changes will lead to a decline in yield and nutrient density in key crops, as well as decreased livestock productivity. Climate change poses unprecedented challenges to U.S. agriculture due to the sensitivity of agricultural productivity and costs to changing climate conditions. Rural communities dependent on agriculture are particularly vulnerable to climate change threats.
Climate change in the Middle East and North Africa (MENA) refers to changes in the climate of the MENA region and the subsequent response, adaption and mitigation strategies of countries in the region. In 2018, the MENA region emitted 3.2 billion tonnes of carbon dioxide and produced 8.7% of global greenhouse gas emissions (GHG) despite making up only 6% of the global population. These emissions are mostly from the energy sector, an integral component of many Middle Eastern and North African economies due to the extensive oil and natural gas reserves that are found within the region. The region of Middle East is one of the most vulnerable to climate change. The impacts include increase in drought conditions, aridity, heatwaves and sea level rise.
The climate in Texas is changing partially due to global warming and rising trends in greenhouse gas emissions. As of 2016, most area of Texas had already warmed by 1.5 °F (0.83 °C) since the previous century because of greenhouse gas emissions by the United States and other countries. Texas is expected to experience a wide range of environmental impacts from climate change in the United States, including rising sea levels, more frequent extreme weather events, and increasing pressure on water resources.
Israel, like many other countries in the Middle East and North Africa, experiences adverse effects from climate change. Annual and mean temperatures are increasing in Israel, with mean temperature expected to increase between 1.6 and 1.8 °C by 2100. There is a reduction in annual precipitation and delayed winter rains. Israel is already experiencing droughts and water shortages. Heatwaves are other natural hazards expected to increase with climate change.
Climate change is the consequence of long-term alterations in the Earth's climate caused by the emission of greenhouse gases such as carbon dioxide (CO2) and methane (CH4). These gases can trap heat in the atmosphere, resulting in global warming and a heightened temperature on our planet. The activities carried out by humans, such as the utilization of fossil fuels, along with large-scale commercial agriculture and deforestation, are accountable for the release of these greenhouse gases. The escalating temperatures and escalating extreme heat conditions, uncertain and progressively unpredictable precipitation, and extreme weather provoke new challenges and exacerbate existing ones.
Lesotho is a country in southern Africa that is already experiencing the negative effects of climate change, including increased frequency of extreme weather, such as droughts, increased rates of soil erosion and desertification, and reduced soil fertility. Lesotho is a landlocked country that is particularly vulnerable to the negative impacts of climate variability and changes in water and food security, as well as adverse conditions to health, human settlements, and the energy sector.
Jordan experiences a environmental issues related to water supply and quality, land pollution, air pollution, rapid modernization, and natural hazards. Many of these issues are exacerbated by the rapid increase in population that Jordan has experienced since 1950, driven mainly by large waves of refugees. In the 1950s, Jordan had a population of 560,000 - this increased to 8.1 million by 2015. This has also contributed to a swift urbanization since the 1960s, at which point 49% of the population lived in rural regions. In 2021, the rural population of Jordan had reduced to 8%. The rural-to-urban migration is heavily influenced by issues of food and job stability, issues that have been thoroughly exacerbated by climate change.
The United Arab Emirates (UAE) faces the impacts of climate change such as water stress, rising sea levels, dust storms, desertification and extreme heat. Climate change threatens the country's water resources, wetland ecosystems, human health, economic stability, and international affairs. The UAE has a hot desert climate and is located on the coast of the Persian Gulf and the Gulf of Oman. Decreasing annual precipitation levels and increased desertification make the country's rural and urban populations vulnerable. Climate change is projected to increase national vulnerabilities in the United Arab Emirates. Sea level rise is expected to impact the UAE's urban infrastructure and marine and wetland ecosystems. The agricultural, fishery, and tourism sectors in the UAE are at risk due to the negative effects of climate change.
