Libya faces a multitude of environmental issues, including water scarcity, land degradation, air pollution, and climate change. With 95% of its land area consisting of desert, Libya is one of the most water-scarce countries globally, and the overuse of water in agriculture has led to depletion and salinity issues. Urbanisation, tree cutting, and overextraction of water have further exacerbated these problems, contributing to soil erosion and desertification. Air pollution, primarily from vehicle emissions, electricity generation, and solid waste burning, poses significant health risks, with particulate matter being responsible for 11% of all deaths in Libya in 2019. Additionally, the country's sewage system is outdated, leading to frequent blockages and the discharge of wastewater into the sea, polluting the marine environment. Climate change impacts, such as rising temperatures, reduced rainfall, and extreme weather events, further compound these challenges, threatening food security and public health.

What You'll Learn
Water scarcity and mismanagement
The impacts of climate change, including droughts, floods, and extreme weather events, damage vital water and sanitation infrastructure. Rising temperatures and reduced rainfall increase irrigation needs, putting further pressure on already scarce water resources. Libya's annual rainfall averages between 200 and 600 millimetres in the most arable portions of the country, and higher temperatures are causing this to decrease. This leads to increased water extraction, which, in turn, impacts the availability of water for human use.
The Great Man-Made River Project (GMMRP), a network intended to provide national water coverage, has suffered significant damage due to conflict and power cuts. The project brings water from fossil aquifers beneath the Sahara to the populated coastal areas of Libya. However, these aquifers are non-renewable and cannot be recharged by rain, meaning the project is not a long-term solution to water scarcity.
In areas outside of the GMMRP network, there is a proliferation of private wells, which further exacerbates water scarcity and salt intrusion. The absence of wastewater treatment plants means that wastewater and sewage are often discharged directly into the sea, polluting the marine environment, or into poorly insulated black wells, leading to sewage overflows and groundwater contamination.
Urbanisation and tree-cutting are also contributing to water scarcity, as they increase water extraction and impact the natural water cycle. The country's sewage system is outdated and overstretched, with frequent blockages, breakages, and overflows. Poor waste management, including the burning of solid waste, further contributes to water contamination and air pollution.
The United Nations Development Programme (UNDP) is working to improve water security in Libya by extending the life of the Man-Made River and adopting a holistic approach to water management that ensures sustainable, equitable, safe, and gender-sensitive access to water resources. However, Libya has made little progress in developing and implementing national disaster risk reduction or climate change adaptation strategies.

Air pollution from vehicles and industry
Air pollution is a critical global health risk, and in Libya, it is a significant issue. The country's urbanization has led to a rise in vehicle use and construction, which has contributed to poor air quality. Motor vehicles are a primary source of nitrogen oxides, which form a reddish-brown layer of smog over many urban areas. The increase in vehicle use has also led to more frequent traffic blocks, breakages, and overflows, further degrading air quality.
Additionally, Libya's electrical generation is a major contributor to air pollution, with 13 power plant stations, most located along the coast. These plants produce energy from the combustion of heavy oil (20%), light oil (40%), and natural gas (40%), emitting carbon dioxide (CO2) and contributing to global warming. The widespread use of diesel-run electric generators has also reduced air quality in urban areas.
Particulate matter (PM) is another major source of air pollution in Libya, produced mainly from cement manufacturing factories, quarrying, and oil refinery industries. Older adults, over the age of 70, are particularly vulnerable to the health impacts of PM, accounting for approximately 67% of PM-related deaths.
The country's oil and petrochemical industries have also caused serious pollution, with oil storage facilities and pipelines targeted during the civil war, exacerbating existing pollution problems. Poor waste management, including the burning of solid waste, has further intensified air pollution and the risk of respiratory illnesses.
Overall, air pollution from vehicles and industry is a severe problem in Libya, impacting public health and the environment, and requiring proactive measures to mitigate its consequences.

Poor waste management
Libya is facing a multitude of environmental issues, with water scarcity being a significant concern. The country's water infrastructure is outdated and has suffered damage during the conflict, with power cuts and a lack of repairs exacerbating the problem. This has led to water mismanagement, with sewage and wastewater often being discharged directly into the sea or into poorly insulated black wells, causing severe marine pollution and groundwater contamination.
The management of domestic, industrial, and medical waste was inadequate even before the conflict and has likely deteriorated since. The conflict has also generated significant amounts of debris, especially in urban areas, overwhelming the already struggling waste management systems. The lack of proper waste management facilities and effective governance has led to environmental degradation and poses risks to public health.
Libya's sewage system is outdated and overburdened, with frequent blockages, breakages, and overflows. This results in sewage mixing with groundwater, leading to widespread flooding and severe water contamination, threatening the foundations of buildings and forcing families to relocate. The combination of water mismanagement, urbanization, and climate change has severely impacted agricultural productivity and food security.
To address these challenges, comprehensive planning and long-term strategies are necessary. The United Nations Development Programme (UNDP) is working to improve water security and promote climate-smart agricultural methods to reduce water overuse and soil erosion. Additionally, local initiatives and individual efforts play a crucial role in community resilience, but a more holistic and proactive approach is needed to effectively mitigate the potential consequences of climate change and environmental degradation.

Climate change and extreme weather
Libya is highly susceptible to the adverse effects of climate change. The country is already experiencing rising temperatures, reduced rainfall, desertification, and extreme weather events such as sand and dust storms, rainstorms, and floods. These climate-induced factors are causing soil erosion and creating more dust, which is likely to lead to even more frequent extreme weather events.
The combination of rising temperatures and reduced rainfall increases irrigation needs, putting further pressure on Libya's already scarce water resources. The country is one of the most water-scarce in the world, and water mismanagement is a significant issue. The Great Man-Made River Project (GMMRP), which aims to provide national water coverage, has outdated infrastructure and has suffered significant damage in recent years, with major leakages and contamination in some areas.
The depletion of underground water due to overuse in agriculture is causing salinity and seawater penetration into coastal aquifers. Additionally, in areas outside the GMMRP network, the unregulated proliferation of private wells exacerbates water scarcity and salt intrusion. The absence of wastewater treatment plants in these areas leads to the discharge of wastewater and sewage directly into the sea, polluting the marine environment, or into poorly insulated black wells, resulting in sewage overflows and groundwater contamination.
The impacts of climate change are also affecting Libya's agricultural productivity and food security. The increased frequency and intensity of extreme weather conditions, including droughts and floods, damage vital water and sanitation infrastructure and services and impact food supplies. Desertification, driven by high urbanization rates and overexploitation of water resources and natural vegetation, is another pressing environmental threat, risking the loss of already limited arable land.
To address these challenges, Libya has signed and ratified several international agreements, including the United Nations Framework Convention on Climate Change, the Paris Climate Accord, the Kyoto Protocol, and the United Nations Convention to Combat Desertification. However, the country has yet to submit the necessary policies, plans, or reports to demonstrate its commitment to mitigating climate change.

Land degradation and desertification
Libya is a country that is primarily comprised of desert, with approximately 95% of its land area being desert. As a result, Libya has long faced water stress and water scarcity, which has been exacerbated by conflict, a lack of repairs to water infrastructure, and power cuts. The Great Man-Made River Project (GMMRP), which aims to bring water from fossil aquifers beneath the Sahara to the populated coastal cities of Libya, has suffered significant damage and is not a long-term solution due to the finite nature of the fossil reserves.
The combination of water scarcity, conflict, and weak environmental management has contributed to land degradation and desertification in Libya. Desertification is one of the most pressing environmental threats in Libya, driven by high rates of urbanization, overexploitation of water resources, and natural vegetation removal. With eighty percent of Libya's population concentrated in coastal cities, the rise in construction and vehicle use has also contributed to land degradation. The cutting down of trees and the overextraction of water further increase dust and erosion in the country, leading to more frequent sand and dust storms, which have a heavy toll on the economy, agriculture, and public health.
The impacts of land degradation and desertification in Libya include the loss of already limited arable land, reduced agricultural productivity, and potential impacts on food security. The country's sewage system is outdated and overstretched, with frequent blockages, breakages, and overflows, further polluting the land and water sources. The absence of wastewater treatment plants means that wastewater and sewage are often discharged directly into the sea or into poorly insulated black wells, contaminating groundwater and leading to sewage overflows.
Climate change and rising temperatures further compound the issues of land degradation and desertification in Libya. The increased use of diesel-run electric generators due to the energy crisis has reduced air quality in urban areas and intensified the impacts of climate change. Libya's vulnerability to the adverse effects of climate change, such as droughts, floods, and extreme weather events, has hindered the development and implementation of disaster risk reduction strategies and climate change adaptation plans.
To address these issues, Libya has signed and ratified various international agreements, such as the United Nations Framework Convention on Climate Change, the Paris Climate Accord, the Kyoto Protocol, and the United Nations Convention to Combat Desertification. However, there has been little progress in submitting the requisite policies, plans, or reports. The United Nations Development Programme (UNDP) is working to improve water management and extend the life of the Man-Made River Project, but environmental protection and governance remain a low priority due to the country's political and economic instability.
