Separating as they do the Arabic, Persian, Russian, and Turkish states or cultural areas, large sections of the Turkish borders have been subject to conflicts throughout history. The 16th century was marked by chronic conflicts between the Ottoman Empire and Persia, which made no major changes to the borders defined between the two states by the Treaty of Chaldiran in 1514. Conflict between Russia and the Ottomans, which was intense in the 19th century, resulted in many changes in the borders, especially following the end of the 1877-1878 war, before those borders were permanently defined by the Treaty of Moscow (1921). Turkey’s borders with Iraq and Syria were defined after the dissolution of the Ottoman Empire and the British and French occupation of the former provinces of the Sublime Porte following the end of World War I in October 1918. The western borders were defined by the retreats and advances of the Ottoman Army during the Balkan Wars of 1912 and 1913 and were confirmed at the Conference of Lausanne, in 1923.
The Turkish borders were highly militarized throughout the 20th century and remain so today: despite the short-lived Balkan Pact of 1934 between Turkey, Greece, Romania, and Yugoslavia, relations between Ankara and Athens were often tense; the borders with Bulgaria and in the Caucasus were heavily militarized during the Cold War, as were the borders with Iran, Iraq, and Syria, which divide Kurdistan into four state entities. The Armenian-Turkish border has remained closed since the Karabakh conflict between Yerevan and Baku (1988-1994), which intensified after the dissolution of the USSR in December 1991.
Geography and Climate
Eastern Thrace – which includes the provinces of Edirne, Kırklareli, and Tekirdağ, as well as the European part of Istanbul – represents only 3 percent of the total area of the country (780,000 square kilometres). The population of Thrace outside Istanbul is 1,521,328, or 2.1 percent of the total population.
The ‘Great Istanbul’ projects put forward by the government of Prime Minister Erdoğan include, in particular, a third bridge connecting Europe and Asia, with the aim of attracting an average of two million people to this area in the near future.
Turkey has few lakes – the largest is Lake Van, with an area of 3,755 square kilometres – but it has many rivers, including the Tigris (1,900 kilometres) and the Euphrates (2,780 kilometres), which have their sources in the same area; the Kızılırmak (Red) River (1,150 kilometres); the Yeşilırmak (Green) River (520 kilometres); and the Büyük and Küçük Menderes (Great and Little Maeander) rivers (548 kilometres and 175 kilometres respectively).
The landscape of Turkey is diverse, with strong contrasts, from Thrace to the Caucasus, including coastal regions and Anatolian steppes. This diversity affects the climate, which is Mediterranean on the coasts of the Aegean and the Mediterranean Sea, temperate and rainy on the coasts of the Black Sea, continental in the central parts, semi-arid in the south-east, and continental, with Siberian winds, along the Caucasus Mountains borders with Iran and Armenia.
The maximum temperatures in Istanbul range from 18 to 28 °C during the summer and decrease to an average of 5 °C during the winter. Ankara’s temperature varies seasonally from 0 to 30 °C. The average annual temperature in Izmir and much of the Mediterranean area is always high (16 °C). The temperatures range seasonally from 3 to 40 °C in Şanlıurfa; minus 2 to about 40 °C in Diyarbakır; minus 12 (with minimum temperatures as low as minus 35) to 27 °C in Erzurum; and 3 to 26 °C in Zonguldak, on the Black Sea coast. Rainfall varies considerably by region and season, ranging from 10 to 50 millimetres in Ankara; from 20 to 70 millimetres in Diyarbakır and Şanlıurfa; from 21 to 70 millimetres in Erzurum; from 21 to 105 millimetres in Istanbul; and from 50 to 140 millimetres in Zonguldak. Seasonal variations explain the drought observed in much of Turkey, especially between June and September.
A fault line runs straight across Anatolia from the south-west to the north-east. The fault line stretches along the plate boundary in a zone of collision between the Arabian plate in the east and the Anatolian plate in the west. The northward migration of the Arabian plate causes horizontal fault slips, storing strain energy which, when released, results in earthquakes.
Most of the earthquakes occur in the so-called North Anatolian Fault zone (parallel to the Black Sea coast), as well as in the East Anatolian Fault zone (in Turkish Kurdistan). Turkey’s most recent devastating earthquake, with a 7.6 magnitude on the Richter Scale, took place on 17 August 1999 in the Kocaeli province in West Turkey. The epicentre was located to the south-west of the city of İzmit, 80 kilometres from Istanbul, in a densely populated and highly industrialized area. The earthquake took place in the middle of the night, when most people were in bed asleep, and in densely populated area, which explains the high death toll – conservative estimates put the figure at around 17,000 – and number of casualties – 45,000 injured. About 70 percent of the buildings, including many industrial facilities, sustained heavy damage and collapsed. On the whole the infrastructure suffered severely. At the time the total material damage was estimated at USD 5 billion.

Biodiversity and Natural Environment
The diverse natural environment of Turkey is exemplified by two internationally recognized sites: Pamukkale, where mineral-rich waters have turned the area into a ‘cotton castle’, and Cappadocia, a volcanic area where basaltic cones form impressive, inaccessible towers that have long been a place of worship and hermitage.
Law No. 2873 on National Parks, which came into force in 1983, divides Turkey’s natural heritage into four categories: 33 national parks (including Aladağlar National Park, Uludağ National Park, Beydağları Coast National Park, Lake Beyşehir, Gala Gölü, and Kazdağı and 16 [check] nature parks (including Lake Abant Nature Park, Çorum-Çatak Nature Park, Gölcük Nature Park, and Polonezköy). It further classifies 35 [check] nature reserves, for the protection of the species they are home to (including Bolu Hazelnut, the Saka Gölü Nature Reserve Area/Lake Saka Nature Reserve Area, Büyük Menderes, Marmaris, and Mount Nemrut.
Turkey is also rich in minerals. It has about 65 percent of world boron reserves – the annual Turkish production of boron is 2.2 million tons per year – and Turkey is the tenth country in the world in total production of minerals; it produces around 60 minerals – including chromium, copper (more than 60,000 tons per year), bauxite, manganese, sulphur, nickel, marble, coal, and, marginally, gold – which produce an annual revenue of USD 2.5 billion.
Another cause of pollution is the massive use of coal (mostly lignite, of which Turkish reserves amount to 12.3 billion tons). Turkish power plants consume about 79 million tons of lignite per year (76 percent of the total amount), whereas industry and the private sector consume 10 and 14 million tons respectively, primarily for heating. Coal distributed by municipalities as charity contributes to air pollution and reduces visibility in medium-sized cities, such as Denizli, during winter. Local governments are not the only parties responsible for the pollution; the central government does not exercise control in the excessive use of coal of the development of megaprojects.
Huge water projects undertaken in the 1960s had significant ecological consequences. For example, the Southern Anatolia Project (GAP), which supplies 12 percent of the country’s electricity, has profoundly altered the landscape and threatened to submerge the ancient site of Hasankeyf. Other dam projects are currently underway in the Black Sea Region, despite intense local opposition.
