Lebanon is a small country in the Eastern Mediterranean, located at approximately 34˚N, 35˚E. It stretches along the eastern shore of the Mediterranean Sea and its length is almost three times its width. From north to south, the width of its terrain becomes narrower. Lebanon's mountainous terrain, proximity to the sea, and strategic location at a crossroads of the world were decisive factors in shaping its history.[1]
The country's role in the region, as indeed in the world at large, was shaped by trade.[1] It serves as a link between the Mediterranean world and India and East Asia.[1] The merchants of the region exported oil, grain, textiles, metal work, and pottery through the port cities to Western markets.[1]
Physical geography and regions
The area of Lebanon is 10,452 square kilometres (4,036 sq mi).
The physical geography of Lebanon is influenced by natural systems that extend outside the country.[1] Thus, the Beqaa Valley is part of the Great Rift system, which stretches from southern Turkey to Mozambique in Africa.[1] Like any mountainous country, Lebanon's physical geography is complex.[1] Land forms, climate, soils, and vegetation differ markedly within short distances.[1] There are also sharp changes in other elements of the environment, from good to poor soils, as one moves through the Lebanese mountains.[1]
A major feature of Lebanese topography is the alternation of lowland and highland that runs generally parallel with a north-to-south orientation.[1] There are four such longitudinal strips between the Mediterranean Sea and Syria: the coastal strip (or the maritime plain), western Lebanon, the central plateau, and eastern Lebanon.[1]
The extremely narrow coastal strip stretches along the shore of the eastern Mediterranean.
The western range, the second major region, is the
The third geographical region is the
Emerging from a base south of Homs in Syria, the eastern mountain range, or Anti-Lebanon (Lubnan ash Sharqi), is almost equal in length and height to the Lebanon Mountains.[1] This fourth geographical region falls swiftly from Mount Hermon to the Hawran Plateau, whence it continues through Jordan south to the Dead Sea.[1] The Barada Gorge divides Anti-Lebanon.[1] In the northern section, few villages are on the western slopes, but in the southern section, featuring Mount Hermon (2860 meters), the western slopes have many villages. Anti-Lebanon is more arid, especially in its northern parts, than Mount Lebanon and is consequently less productive and more thinly populated.[1]

Climate
Lebanon has a Mediterranean climate characterized by a long, hot, and dry summer, and a cool, rainy winter.[1] Fall is a transitional season with a lowering of temperature and little rain; spring occurs when the winter rains cause the vegetation to revive.[1] Topographical variation creates local modifications of the basic climatic pattern.[1] Along the coast, summers are warm and humid, with little or no rain.[1] Heavy dews form, which are beneficial to agriculture. The daily range of temperature is not wide.[1] A west wind provides relief during the afternoon and evening; at night the wind direction is reversed, blowing from the land out to sea.[1]
Winter is the rainy season, with major precipitation falling after December.[1] Rainfall is generous but is concentrated during only a few days of the rainy season, falling in heavy cloudbursts.[1] The amount of rainfall varies greatly from one year to another.[1] A hot wind blowing from the Egyptian desert called the khamsin (Arabic for "fifty"), may provide a warming trend during the fall but more often occurs during the spring.[1] Bitterly cold winds may come from Southern Europe.[1] Along the coast the proximity to the sea provides a moderating influence on the climate, making the range of temperatures narrower than it is inland, but the temperatures are cooler in the northern parts of the coast where there is also more rain.[1]
In the
The
Because of their altitudes, the Anti-Lebanon Mountains receive more precipitation than the Beqaa Valley, despite their remoteness from maritime influences.[1] Much of this precipitation appears as snow, and the peaks of the Anti-Lebanon, like those of the Lebanon Mountains, are snow-covered for much of the year.[1] Temperatures are cooler than in the Beqaa Valley.[1]
The Beqaa Valley is watered by two rivers that rise in the watershed near Baalbek: the
Smaller springs and streams serve as tributaries to the principal rivers.[1] Because the rivers and streams have such steep gradients and are so fast moving, they are erosive instead of depository in nature.[1] This process is aided by the soft character of the limestone that composes much of the mountains, the steep slopes of the mountains, and the heavy rainstorms.[1] The only permanent lake is Lake Qaraoun, about ten kilometers east of Jezzine.[1] There is one seasonal lake, fed by springs, on the eastern slopes of the Lebanon Mountains near Yammunah, about 40 kilometres (25 mi) southeast of Tripoli.[1]
Temperatures are rising in Lebanon as a part of global warming.[3] Lebanon is considered to be part of the Fertile Crescent, yet in the meantime with the severe climate changes, it might lose fertility.[4]

Water in Lebanon
Water is becoming a scarce resource in Lebanon due to climate change, which leads to different rainfall patterns as well as to inefficient methods of distribution within the country. Most of Lebanon's rainfall is in the four months of winter, but over the last 45 years, the Ministry of Environment (Lebanon) estimates that rainfall has decreased overall between 5 and 20 percent.[9] The coastal strip of Lebanon gets approximately 2,000 mm of rain per year, while the Beqaa Valley to the east gets only one-tenth as much.[10] In 2004, only about 21% of households across Lebanon had constant access to water in the summer months, with most of those households concentrated in or near Beirut.[9] It is predicted that in future years, there will be higher temperatures, lower rainfall, and longer droughts, leading to even less access to water.[10] According to the Ministry of Environment, several factors that are putting stress on Lebanon's water resources are unsustainable water management practices, increasing water demand from all sectors, water pollution, and ineffective water governance.[11] Lebanon has struggled with inadequate water and sanitation services for many years.[12] The factors with the greatest effect on quality and quantity of water resources in Lebanon are population growth, urbanization (88% of the population now lives in urban areas), economic growth, and climate change.[13] In recent years, population growth has been increased rapidly with the addition of many Syrian refugees.[12] Some new projects have been proposed to restructure the water sector. Currently, over 48 percent of water supplied by the public system is lost through seepage and wastewater networks are extremely poor, or even non-existent in some areas.[12] One project that is currently being implemented by the Ministry of Environment in collaboration with the United Nations Development Programme (UNDP) focusses on harvesting rainwater from agricultural greenhouse tops in order to increase water harvesting and reduce the pressure on pumping groundwater.[13] This project is expected to increase water availability during the especially critical months of late summer and early autumn when there is less precipitation, which would help to reduce the risk of salinity in both soil and water, and to increase the resilience of crops faced with prolonged drought.[13] There are also proposed projects that suggest the agricultural sector use recycled waste water to allow for more fresh and potable water for consumption.[13] This would be a huge improvement, as solid-wast treatment facilities are in short supply, and over 92 percent of Lebanon's sewage runs untreated directly into water-courses and the sea.[12] If Lebanon does not reform its water sector, it is likely that there will be chronic and critical water shortages by 2020, which would create needs the Ministry of Energy and Water (MEW) would be unable to meet.[14] Water is becoming a scarce resource and if Lebanon instates reformed practices, the progression forward into future water scarcity can be slowed.
Environmental concerns
Current environmental degradation concerns include deforestation, soil erosion, desertification, air pollution in Beirut from vehicular traffic and the burning of industrial wastes, and pollution of coastal waters from raw sewage and oil spills.
Lebanon's rugged terrain historically helped isolate, protect, and develop numerous factional groups based on religion, clan, and ethnicity.
Air quality in Lebanon
As a result of increasingly hot summers and its location within the Mediterranean region, which is often cited for having long episodes of pollution, Lebanon, Beirut in particular, is at high risk for air pollution.[15] Approximately 93 percent of Beirut's population is exposed to high levels of air pollution, which can most often be attributed to vehicle-induced emissions, whether it be long-range travel or short commuting traffic.[15][16] The cost of air pollution to health may exceed ten million dollars a year.[16] The levels of air pollution in Beirut are increasing annually, and were already above acceptable WHO (World Health Organization) standards by 2011.[16] The most noted pollution in Beirut is particulate matter (street dust), chemicals in the air, and vehicle exhaust. Air pollution is exacerbated by city structure and inadequate urban management as indicated by high buildings on narrow streets, which contain air pollutants.[16] Some recommendations for improvement of air quality include encouragement of carpooling and citywide biking, alternative fuels for vehicles, and a widened public transit sector.[16]
The question of air quality has received considerable attention and funding by Lebanon's foreign partners. Between 2013 and 2017, the Lebanese ministry of environment was granted a donation of over 10 million Euros by Greece and the European Union to establish a national air monitoring network, which included at its peak 25 stations.[17] This network was launched in October 2017 at a major event bringing together 26 different institutions;[18] it was to serve as the cornerstone of Lebanon's National Strategy for Air Quality Management, which was released at the end of the same year.[19] By mid-2019, however, the ministry of environment ceased to maintain and operate this network, involving budgetary restrictions.[17] Stations were subsequently looted, even in central Beirut.
Land pollution in Lebanon
Sukleen, Lebanon's largest waste disposal company has a waste management process that goes through several stages, including clean-up and collection, sorting and composting, and burial.[20] However, many argue that Lebanon needs a much better system for disposal of waste to reduce pollution and environmental degradation. The Litani River is Lebanon's largest river and many farms use the river's water to irrigate land and crops.[21] Because of Lebanon's poor waste management system, a lot of waste and pollution ends up in the Litani and contaminates the crops, in turn endangering the health of consumers and farmers alike, contributing to environmental degradation, as well as hurting the agricultural reputation and economy.[21]
Trash protests of January 2014
In January 2014, protests in the town of Naameh began to arise, effectively blocking disposal of garbage at the landfill for three days.[22] The protests were instated in response to the continued use of the landfill in Naameh beyond the date it was originally meant to close.[23] The landfill began as a six-year project in 1997, but has remained open for seventeen years as of 2015, and without a sufficient alternative location for garbage disposal, it is likely that it will remain open for the foreseeable future.[23] In 1997, Naameh became the country's primary landfill and was initially supposed to hold two million tons of waste.[22] The landfill currently holds ten million tons of trash, and is still in use.[22] Residents of the area in 2014 did not want to extend the landfill agreement, and staged the protests to prevent future plans.[22]
The company in charge of the majority of the area's collection and cleanup of trash is called Sukleen. It serves 364 towns and municipalities within Beirut and Mount Lebanon.[20] The total waste collected by the company rose from 1,140 tons daily in 1994, to 3,100 tons in 2014.[20] Sukleen is the largest government-contracted private waste management company in Lebanon.[22] In response to the protests, which were asking the government for more efficient waste management systems along with the closure of the landfill in Naameh, Sukleen responded to environmentalists by halting service to Beirut and Mount Lebanon for three days.[22] Because the Naameh landfills were closed and Sukleen was out of service, trash began to pile up in the streets of the city, affecting everyone citywide and drawing attention to the issue of city/region waste-management issues.[23]
