GEOGRAPHY

Location: Yemen is located in the Middle East at the southern tip

of the Arabian Peninsula between Oman and Saudi Arabia. It is

situated at the entrance to the Bab el Mandeb strait, which links

the Red Sea to the Indian Ocean (via the Gulf of Aden) and is one

of the most active and strategic shipping lanes in the world.

Size: Yemen has an area of 527,970 square kilometers, including the islands of Perim at the southern end of the Red Sea and Socotra at the entrance to the Gulf of Aden.

Land Boundaries: Yemen’s land boundaries total 1,746 kilometers. Yemen borders Saudi Arabia to the north (1,458 kilometers) and Oman to the northeast (288 kilometers).

Disputed Territory: A long-standing dispute between Saudi Arabia and Yemen was resolved in June 2000 with the signing of the Treaty of Jiddah. This agreement provides coordinates for use in delineating the land and maritime border, including the section in the eastern desert region of Yemen that potentially contains significant amounts of oil. Friction between the two countries in recent years over security of the borders appears to have been alleviated by the establishment of joint border patrols. Following years of dispute between Yemen and Eritrea over ownership of the Hanish Islands and fishing rights in the Red Sea, in 1999 an international arbitration panel awarded sovereignty of the islands to Yemen. Relations between the two countries remain strained, and Yemen continues to protest Eritrean fishing in the disputed territory.

Length of Coastline: Yemen has 1,906 kilometers of coastline along the Arabian Sea, the Gulf of Aden, and the Red Sea.

Maritime Claims: Yemen claims a territorial sea of 12 nautical miles, a contiguous zone of 24 nautical miles, an exclusive economic zone of 200 nautical miles, and a continental shelf of 200 nautical miles or to the edge of the continental margin.

Topography: Yemen occupies the southern end of the Arabian Plateau. The country’s mountainous interior is surrounded by narrow coastal plains to the west, south, and east and by upland desert to the north along the border with Saudi Arabia. The Tihamah is a nearly 419-kilometer-long, semidesert coastal plain that runs along the Red Sea. The interior mountains have elevations ranging from a few hundred meters to the country’s highest point, Jabal an Nabi Shuayb, which is 3,760 meters above sea level. The highland regions are interspersed with wadis, or river valleys, that are dry in the summer months. Most notable is the Wadi Hadhramaut in eastern Yemen, the upper portions of which contain alluvial soil and floodwaters and the lower portion of which is barren and largely uninhabited. Both the eastern plateau region and the desert in the north are hot and dry with little vegetation.

Principal Rivers: Yemen has no permanent rivers.

Climate: Temperatures are generally very high in Yemen, particularly in the coastal regions. Rainfall is limited, with variations based on elevation. The highlands enjoy a temperate, rainy summer with an average high temperature of 21° C and a cool, moderately dry winter with temperatures occasionally dipping below 4° C. The climate of the Tihamah (western coastal plain) is tropical; temperatures occasionally exceed 54° C, and the humidity ranges from 50 to 70 percent. Rainfall, which comes in irregular heavy torrents, averages 130 millimeters annually. In Aden the average temperature is 25° C in January and 32° C in June, but with highs often exceeding 37° C. Average annual rainfall is 127 millimeters. The highest mountainous areas of southern Yemen receive from 520 to 760 millimeters of rain a year. It is not uncommon for the northern and eastern sections of the country to receive no rain for five years or more. The Wadi Hadhramaut in the eastern part of Yemen is arid and hot, and the humidity ranges from 35 percent in June to 64 percent in January.

Natural Resources: Yemen’s principal natural resources are oil and natural gas as well as agriculturally productive land in the west. Other natural resources include fish and seafood, rock salt, marble, and minor deposits of coal, gold, lead, nickel, and copper.

Land Use: Only 2.9 percent of Yemen is considered to be arable land, and less than 0.3 percent of the land is planted with permanent crops. About 4,900 square kilometers of land are irrigated. According to the United Nations, Yemen has 19,550 square kilometers of forest and other wooded land, which constitutes almost 4 percent of total land area.

Environmental Factors: Yemen is subject to sandstorms and dust storms, resulting in soil erosion and crop damage. The country has very limited natural freshwater and consequently inadequate supplies of potable water. Desertification (land degradation caused by aridity) and overgrazing are also problems.

Time Zone: Yemen is three hours ahead of Greenwich Mean Time.
