Kuwait is a country in West Asia, bordering the Persian Gulf, between Iraq and Saudi Arabia.

[1] The boundary between Kuwait and Saudi Arabia was set by the Treaty of Al Uqayr in 1922, which also established the Saudi–Kuwaiti neutral zone of 5,700 square kilometers between the two nations.

[1] In 1966, Kuwait and Saudi Arabia agreed to divide the neutral zone; the partitioning agreement making each country responsible for administration in its portion was signed in December 1969.

[1] Under United Nations (UN) Security Council Resolution 687, after the restoration of Kuwaiti sovereignty in 1991, a UN commission undertook formal demarcation of the borders on the basis of those agreed to in 1963.

[4][5] The summers are relentlessly long, punctuated mainly by dramatic dust storms in June and July when northwesterly winds cover the cities in sand.

[1] Kuwait's winter is colder than in other Persian Gulf countries, such as Bahrain, Qatar or United Arab Emirates.

Kuwait experiences colder weather because it is situated farther north, and because of cold winds blowing from upper Iraq and Iran.

In response to Kuwait becoming the 169th signatory of the Ramsar Convention, Bubiyan Island's Mubarak al-Kabeer reserve was designated as the country's first Wetland of International Importance.

[12] Kubbar Island has been recognised an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of white-cheeked terns.

[1] In the west and north, layers of sand, gravel, silt, and clay overlie the limestone to a depth of more than 210 meters.

[1] On the western side of the Al Rawdatayn geological formation, a freshwater aquifer was discovered in 1960 and became Kuwait's principal water source.

[1] The only other exploited aquifer lies in the permeable zone in the top of the limestone of the Ash Shuaybah field south and east of the city of Kuwait.

[26] Kuwait also has several river-like marine channels around Bubiyan Island, most notably Khawr Abd Allah which is now an estuary, but once was the point where the Shatt al-Arab emptied into the Persian Gulf.

[28] Kuwait's fresh water resources are limited to groundwater, desalinated seawater, and treated wastewater effluents.
