3. The Great Man-Made River Project in Libya: An Overview of the Current Status and Future Prospects

   Salah Hamad, Fawzi Saeid

   Abstract

   The Great Man-Made River Project (GMMRP) was implemented to address Libya’s water scarcity problem by utilizing groundwater instead of desalination due to cost, capacity expansion, and operational considerations. The GMMRP aimed to produce and transport 6.4 million cubic meters of groundwater daily to meet the water demands of northern Libyan urban settlements for domestic, agricultural, and industrial use. The GMMRP has achieved its objectives of improving the quality of life for residents, alleviating pressure on coastal aquifers, and promoting sustainable development, without any adverse environmental impacts. However, the GMMRP has faced significant challenges following the 2011 Libyan civil war. These include a decline in financial resources due to political conflicts, lower oil production and prices, and direct and indirect economic losses from damage caused by armed conflict and lack of security. Additionally, the GMMRP faces a considerable discrepancy between the cost of water production and the price charged to consumers, insufficient revenue generation, and an inability to import critical spare parts and materials for maintenance operations. Other challenges include unclear criteria for water allocation, incomplete information to estimate the costs of development investment plans, frequent electricity supply interruptions, and infrastructure issues. Furthermore, to ensure the project’s sustainability, its recommended to develop a sustainable financial plan, improve billing and collection processes, priorities infrastructure maintenance, and develop effective monitoring and inspection systems. Also, it suggested creating a comprehensive national strategy for managing water resources and prioritizing water supplies for urban, industrial, and agricultural uses. The integration of planning for irrigation water management, investing in treated wastewater, and transparently allocating water among users based on economic, technical, social, and environmental standards are also recommended. Additionally, strengthening security measures, implementing effective pollution control measures, and promoting water-saving technologies and practices. Overall, the GMMRP has been successful in providing a solution to Libya’s water scarcity problem. Still, there is a need for concerted efforts to address the challenges it faces to ensure its sustainability.

4. Groundwater: An Important Resource of Urban Water Supply in Libya

   Salah Hamad, Rod Fensham

   Abstract

   Libya is one of the world’s poorest countries in renewable water resources, with a per capita share of water that is less than 10% of the global average. Water demand will rise with population, economic, and urban growth. Water use will also change in response to construction projects, security threats, climatic change, food security requirements, and crop demand increase, particularly in the north of the country where most of the population is concentrated. 97% of the country’s total water consumption is sourced from groundwater. Springs, local water wells, and the Great Man-Made River Project (GMMRP) are the sources of groundwater used for urban water supplies. The springs slightly contribute to urban water supply in sparsely populated areas, primarily suburbs and villages. Most local water wells are located in urban areas with no other water sources, particularly Al Jabal Al Akhdar, the central regions, Jabal Nafusa, and the Jifarah plain. Only 53.7% of the 1591 water wells are operational. The GMMRP is currently the primary source of water supply for more than 70% of Libyan cities and will contribute to securing 2.3 billion m³ of water annually if all phases are completed. The projected water demand, which is anticipated to be around 10 billion m³ by 2035, cannot be met by the GMMRP alone. Complementary sources, like sewage treatment and saltwater desalination, must be developed to close the imbalance between supply and demand. Finally, water urban water supply services face serious challenges caused by ageing facilities, ongoing armed conflict, political, economic, and institutional instability, and continuous power and fuel supply cuts. Libya’s water problem is more than just a quantitative shortage of fresh water.

   Abstract

   Rainwater harvesting presents a viable solution to address water scarcity challenges in arid regions such as Libya. This chapter explores the potential of rainwater harvesting in Libya, a country characterized by limited water resources due to low precipitation levels and reliance on finite water sources. Traditional methods such as rooftop collection and modern techniques, including dam construction offer opportunities to augment water resources sustainably. However, ensuring the safety and reliability of harvested rainwater is essential, necessitating comprehensive water quality testing and treatment protocols. Despite challenges such as low rainfall and high evaporation rates, innovative solutions based on modern technologies and sustainable practices can enhance water resilience. Selected case studies illustrate practical implementation and outcomes, providing valuable insights for plans. Recommendations include allocating resources for infrastructure development, educating communities, establishing water quality protocols, prioritizing dam construction, strengthening capacity, and formulating supportive policies. Through the implementation of these measures, Libya can effectively address water scarcity challenges and ensure water security for present and future generations.

6. Agricultural Drainage in Libya: History and Perspective

   Mohamed A. Hamilla, Murad Ellafi

   Abstract

   Drainage in irrigated lands has been installed to manage salinity and waterlogging problems. Less than 10% of all irrigated area requiring drainage is currently drained in developing countries. This chapter aims to (1) review the agricultural drainage development in Libya for the last 70 years. (2) analyze the existing drainage systems and highlights their pros and cons. (3) demonstrate the suggested solutions to improve the drainage systems in Libya. During the 1950s, ditches were randomly dug in fields, and farms suffering from salinity and waterlogging tended to be left. Between 1960–1984, several agricultural projects were established. Still, drainage was neglected or installed without maintenance programs. Therefore, hundreds of hectares were lost due to waterlogging and salinity. In 1985, the General Administration of Irrigation and Drainage (GAID) was established. Between 1985–2017, GAID managed to prepare technical reports based on several field visits and investigations for the current agricultural projects in Libya. The visits covered agricultural projects in three geographical locations: east, central, and southwest Libya. The GAID suggested that installing and maintaining proper drainage systems would help to improve the efficiency of more than 30,000 ha in those geographical locations.
