Tunisia is located in Northern Africa and is bordered by the Mediterranean Sea, Algeria, and Libya. Due to its geographical location, the country is divided into three regions: the Mediterranean region in the Northeast, the arid steppe region in the center, and a desert region in the South. [1] When looking at the impacts of climate change, each region faces its own category of climate threats, with sea level rise jeopardizing the water quality of coastal aquifers in the Northeast and the center and Eastern regions of the country affected by variable precipitation, rising temperatures and increased extreme weather events such as floods. [2]
Tunisia has recognized the urgent need to address climate change and is involved in international climate action. In 2016, Tunisia signed and ratified the Paris Agreement, committing to global efforts to limit global warming to well below 2 °C. [3] In 2021, it submitted and revised an Updated Nationally Determined Contributions (NDCs), which has set an emissions reduction target of 45% below 2010 levels, by 2030. [4] Through commitments like these Tunisia not only commits to solving its own diverse climate issues but also commits to decreasing emissions on a global scale.
Tunisia generates the majority of its greenhouse gas emissions through a variety of industries. In 2022, Tunisia produced 32.5% of its CO2 emissions through electricity and heat production, 18.3% in industry, 30.8% through the transportation sector, 8.8% in residential settings, and around 4% through agriculture. [5] On a global scale Tunisia remains among the lower end of Greenhouse Gas contributors, ranking at 7th in Africa for CO2 emissions per capita and landing at 90th globally. [5] With transportation and electricity and heat producers contributing a combined 64% of total CO2 emissions, mitigation efforts in these sectors will become increasingly vital as Tunisia works to combat the variety of environmental and social issues caused across the country by climate change. [5]
Tunisia is anticipated to be one of the countries most impacted by temperature change caused by global warming. The United Nations predicts that Tunisia will experience an average annual temperature of 69.3 °F between 2040 and 2059, compared to a global predicted average of 61 °F. [6] Similarly, the Tunisian National Institute of Meteorology predicts a temperature increase of 1.8 °C by 2050 and an increase of 3 °C by 2100 in Tunisia. [6] The dramatic increase in temperature will likely act as the most pressing climate change factor in Tunisia and directly impact human health with potential to generate up to two dozen climate related deaths in the Nabeul region, due to its position along the Mediterranean coast, as soon as 2020-2039. [6]
Climate change exacerbates the issue of water security in Tunisia. The country relies heavily on coastal groundwater resources to support both irrigated agriculture and the drinking water supply. [7] Unsustainable pumping practices, such as pumping beyond a renewable capacity, have depleted the groundwater at unsustainable rates and led to seawater intrusion in aquifers. [7] Overexploitation of groundwater paired with the threat of sea level rise in the Mediterranean Sea, exacerbated by climate change, increases the rate at which salt water begins to infiltrate aquifers, making the water unusable.
Globally, Tunisia has consistently been acknowledged as one of the most water stressed countries, ranking at twentieth most stressed in a World Resource Institute assessment. [6] In the past several years, Tunisia has seen a stark decrease in rainfall following a drought that lasted from 2017 to 2020. With 110 million cubic meters of rain from September 2022 to March 2023, average rainfall saw a significant decline compared to an annual average of 520 million cubic meters prior to 2020. [6] Because of a combination of groundwater depletion, quality degradation, and a predicted increased drinking water demand, Tunisia is expected to lose 75% of its coastal water resources by 2050. [6]
Drinking water scarcity remains a looming threat for people living in Tunisia. The United Nations predicts Tunisia to experience a 38% increase in drinking water demand, while simultaneously seeing a decrease between 31% and 61% of renewable water resources by 2100. [6] The country experienced historic water shortages in 2023, causing the Tunisian government to implement water rationing for the first time in several areas including Hammamet, Sousse, Monastir, Mahdia, and Sfax. [6]
Tunisia relies heavily on rain-fed crops to sustain their agricultural sector and rural communities. Agriculture is a key industry in Tunisia, accounting for 10% of their GDP in 2022 and responsible for 14% of the country's workforce. [6] However, as climate change impacts local weather patterns, Tunisia can expect to experience higher rates of drought, decreasing crop-yields and creating issues of food production. [8]
Major crops in Tunisia such as wheat, barley, and olive can expect to be most heavily impacted by the increased drought. The country has already experienced a decrease in 12% of agricultural production from 2000 to 2017. [8] Issues in agricultural production can result in food scarcity issues among Tunisian citizens. A January 2023 poll found 73% of Tunisians reported being "somewhat concerned" or "very concerned" about their ability to provide their household with food in the next six months. [6]
Crop-yields in Tunisia are also impacted by soil degradation. Across the country an estimated 70% of land is impacted by erosion, salinization, and nutrient depletion. [8] This process is heavily sped-up by increasing temperatures as the reduction of soil moisture and erosion rates are directly impacted by heat. [8]
As already 75% of agriculture land in Tunisia faces desertification, women farmers heavily suffer from the devastating effects of climate change. [9]
In addition to agriculture, fisheries are crucial to Tunisia' s GDP, food security, and the livelihood of coastal communities. Climate change poses a large threat to the resilience of marine ecosystems globally, but especially in the Mediterranean Sea which represents 7.5% of the world's worlds marine fauna, and 18% of the worlds marine flora, while only accounting for 0.7% of the worlds ocean area, creating high concentrations of biodiversity in the region. [10] The temperatures in the Mediterranean Sea are rising 25% faster than in the rest of the ocean on average, which puts the marine ecosystems that support the production of fisheries in Tunisia at risk of collapsing. [11]
Tourism acts as a major player in Tunisias national and regional economies. In 2024, tourism was projected to contribute 23 billion Tunisian Dinar and accounts for 14% of overall economic production across the country. [9] Tourism also acts as a primary sector for job growth, with a 3.9% increase year-to-year, predicted to account for 418,000 jobs in 2024. [9] Tourism in Tunisia is reliant on its geographic diversity, with tourism focused mainly in the mountainous and coastal regions. Climate change is expected to impact coastal tourism as sea levels rise and beaches erode. [12] Furthermore, as extreme weather becomes more frequent, events such as sea surges and storms are expected to further amplify the deterioration of Tunisias coasts, decreasing the potential for tourism in coastal areas. [12]
In the mountainous regions, Tunisia’s ski resorts, such as those in the Kroumirie Mountains, depend on a stable winter climate. However, rising temperatures are expected to shorten the winter season, reducing snowfall and, consequently, the potential for winter sports such as skiing, snowboarding, and other winter sports. [12] As the length and quality of the winter season diminish, Tunisia may see a reduction in the number of tourists visiting for winter sports, affecting not only the resorts but also the surrounding local economies that rely on seasonal tourism.
As mentioned above, rising sea levels, driven by global climate change, pose significant risks to Tunisia's coastal regions, leading to a range of issues that directly affect both the environment and local communities. As sea levels rise, coastal areas will begin to erode, which threatens to submerge or severely damage critical infrastructure, including tourism centers and residential areas. [12] This will have a heavy impact on Tunisia, where tourism plays a vital role in the national economy by contributing to the GDP and providing employment.
Approximately 68% of Tunisia's coastline is classified as moderately to very highly vulnerable to the effects of sea level rise and coastal erosion. Projections anticipate sea levels could rise between 30 and 50 centimeters by the end of the 21st century. [6] This rise, combined with more frequent and intense storm surges, will exemplify the erosion of coastal areas, leading to further loss of land, property, and cultural heritage sites.
Beyond physical damage to coastal areas, rising sea levels also threaten freshwater resources through saltwater intrusion into coastal aquifers. Tunisia, already facing significant water scarcity, relies heavily on underground freshwater reserves for drinking water and irrigation. [7] As sea levels rise, saltwater can seep into these groundwater supplies, making them undrinkable and unsuitable for agricultural use. The intrusion of salt water will worsen the country’s water shortage, impacting agriculture - particularly in the coastal plains - and reducing the availability of clean drinking water for growing urban populations. With already diminishing freshwater sources, saltwater intrusion will place additional pressure on Tunisia's water supply, affecting food security and public health. [6]
The Tunisian Government aims to achieve 35% renewable energy by 2030 compared to the 3% it holds now. [13] Additionally, it plans for renewable sources to cover 50% of the country’s electricity needs by 2035, and 100% by 2050. [13] These targets represent 75% of Tunisia's commitment to reducing greenhouse gas (GHG) emissions. [14] While these climate goals are ambitious, the government’s methods for achieving them are heavily criticized. Specifically, there have been concerns over the forced relocation of residents and the confiscation of agricultural land for renewable energy projects, such as solar and wind farms. [15]
In order to reach their climate goals, the Tunisian government has continued to reform their policy planning process following the 2011 revolution, emphasizing a participatory process and empowering local authorities. [16] The implementation of the Local Authorities Code, adopted April 2018, gives power to local government to make decisions about environmental management. [16] Beginning 2021, Tunisia has taken strides towards developing a National Adaptation Plan, which centers land use planning and economic and social development. [16]
According to the Updated Nationally Determined Contribution (NDC) submitted in 2021,Tunisia has set a target to reduce emissions by 13% by 2030 compared to a business-as-usual scenario, with an additional 47% reduction achievable dependent on international support. [17] The revised NDCs also outline key actions in sectors such as renewable energy, energy efficiency, agriculture, and water management, focusing on both mitigation and adaptation strategies. The agri-food sector is a critical part of Tunisia's economy and is especially vulnerable to climate change impacts. These threats to food production and water availability could jeopardize livelihoods and food security, underscoring the importance of these climate goals.
Communities in Tunisia have come together to develop creative mitigation plans such as harvesting rainwater, waste recycling, to energy saving street-lights. The UN Capital Development Fund has worked with the Tunisian government to strengthen local mitigation efforts through Local Climate Adaptive Living Facility (LoCAL), which is funding from the European Union. [18] This allows for money to be channeled into bottom-up approaches to mitigation climate change effects and allows communities to implement mitigation efforts on a case to case basis. The LoCAL Facility gives climate finance to local governments in the form of Performance Based Climate Resilience Grants (PBCRGs). The funds incentivize climate-proof local development and encourage local participation and projects. [19]
Although Tunisia is labeled as being a climate hot spot, Tunisian President Kris Saied has failed in putting climate adaptation as a priority. His government has been slow in implementing effective climate policies and has limited investment in climate resilience, particularly in the agriculture sector and water management. [15] Efforts in environmental governance and climate change has taken the backseat to the political instability in Tunisia.
Even so, there have been adaptations to climate change that have mainly focuses on managing water scarcity, coastal erosion from sea level rise, and adapting to extreme weather events. Tunisia developed the National Adaptation Plan (NAP) to guide climate resilience in various sectors such as energy, water, agriculture, and health. [20] Tunisia also branches out to international funding to support their initiatives.
The Tunisian Government has made continuously large strides to affirming their commitment to reaching climate goals. With the ratification of the Kyoto Protocol in January 2003, Tunisia made its promise alongside other countries to limit greenhouse gas emissions. [21] The country later affirmed its climate vows with the signing of the Paris Agreement in April 2016 and later ratifying it in 2017, a global commitment which ensures that global temperatures don't warm past 2 °C. [21]
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
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.
The effects of climate change on small island countries are affecting people in coastal areas through sea level rise, increasing heavy rain events, tropical cyclones and storm surges. These effects of climate change threaten the existence of many island countries, their peoples and cultures. They also alter ecosystems and natural environments in those countries. Small island developing states (SIDS) are a heterogenous group of countries but many of them are particularly at risk to climate change. Those countries have been quite vocal in calling attention to the challenges they face from climate change. For example, the Maldives and nations of the Caribbean and Pacific Islands are already experiencing considerable impacts of climate change. It is critical for them to implement climate change adaptation measures fast.
Climate changein the Caribbean poses major risks to the islands in the Caribbean. The main environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean. Temperature rise of 2°C above preindustrial levels can increase the likelihood of extreme hurricane rainfall by four to five times in the Bahamas and three times in Cuba and the Dominican Republic. A rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold. The Bahamas is expected to be the most affected because at least 80% of the total land is below 10 meters elevation.
Climate change is causing Egypt’s already hot and arid climate to experience environmental stresses including extreme temperatures, droughts, floods, and sea level rise. These extreme conditions will have significant impacts on the lives of Egyptians resulting in food insecurity, water scarcity, and economic destabilization.
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 Senegal will have wide reaching impacts on many aspects of life in Senegal. Climate change will cause an increase in average temperatures over west Africa by between 1.5 and 4 °C by mid-century, relative to 1986–2005. Projections of rainfall indicate an overall decrease in rainfall and an increase in intense mega-storm events over the Sahel. The sea level is expected to rise faster in West Africa than the global average. Although Senegal is currently not a major contributor to global greenhouse gas emissions, it is one of the countries most vulnerable to climate change.
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.
Vietnam is among the most affected countries by global climate change. A large number of studies show that Vietnam is experiencing climate change and will be severely negatively affected in coming decades. These negative effects include sea level rise, salinity intrusion and other hydrological problems like floods, river mouth evolution and sedimentation. Natural hazards such as cold waves, storm surges will increase in frequency, with negative effects on the country's development, infrastructure and economy.
The climate of Greece is changing by way of increased drought, flooding, wildfires and sea level rise. These extreme weather conditions are likely to become more frequent and as a result landscapes and biodiversity will be affected. Climate change will also cause human activities such as land-use change, urbanisation and soil degradation to further affect Greek's ecosystems. Ecosystems in Greece are already at their tipping point, close to their environmental limits. Policies and laws have been put in place by the Greek government to try to manage these issues.
Italy is experiencing widespread impacts of climate change, with an increase in extreme events such as heatwaves, droughts and more frequent flooding; for example, Venice is facing increasing issues due to sea level rise. Italy faces many challenges adapting to climate change including the economic, social, and environmental impacts that climate change creates, and an increasingly problematic death toll from the health risks that come with climate change.
Due to its geographical and natural diversity, Indonesia is one of the countries most susceptible to the impacts of climate change. This is supported by the fact that Jakarta has been listed as the world's most vulnerable city, regarding climate change. It is also a major contributor as of the countries that has contributed most to greenhouse gas emissions due to its high rate of deforestation and reliance on coal power.
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.
Climate change in South Africa is leading to increased temperatures and rainfall variability. Evidence shows that extreme weather events are becoming more prominent due to climate change. This is a critical concern for South Africans as climate change will affect the overall status and wellbeing of the country, for example with regards to water resources. Just like many other parts of the world, climate research showed that the real challenge in South Africa was more related to environmental issues rather than developmental ones. The most severe effect will be targeting the water supply, which has huge effects on the agriculture sector. Speedy environmental changes are resulting in clear effects on the community and environmental level in different ways and aspects, starting with air quality, to temperature and weather patterns, reaching out to food security and disease burden.
Climate change in Fiji is an exceptionally pressing issue for the country - as an island nation, Fiji is particularly vulnerable to rising sea levels, coastal erosion and extreme weather. These changes, along with temperature rise, will displace Fijian communities and will prove disruptive to the national economy - tourism, agriculture and fisheries, the largest contributors to the nation's GDP, will be severely impacted by climate change causing increases in poverty and food insecurity. As a party to both the Kyoto Protocol and the Paris Climate Agreement, Fiji hopes to achieve net-zero emissions by 2050 which, along with national policies, will help to mitigate the impacts of climate change.
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 having significant and diverse impacts, like higher temperatures, lower precipitation and sea level rise on Saudi Arabia's environment, society and economy. agricultural, fishing and tourism industries. Although they only emit a combined 2.52% of the global greenhouse gas emissions, the Arab states of the Persian Gulf still contribute a not insignificant amount to climate change via their economies that are based heavily on oil and gas exportation.
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.
Situated along the coast of the Mediterranean Sea and North Africa, Libya is highly vulnerable to the effects of climate change.
