Ajariaautonomous republic, Georgia also spelled Adjara , Adzhariya , or Adžarija

Two east-west ranges, the Ajar-Imeretinsky in the north and the Shavshetsky in the south, rise from the Black Sea coastal lowlands to more than 9,200 feet (2,800 metres). Between the ranges lies the Ajaristskali River valley, which is closed at the eastern end by a third range, the Arsiyan Mountains. The coastal lowland area, which widens somewhat to the south of Batumi and again in the north around Kobuleti, has a humid subtropical climate with average January temperatures ranging from 41 to 46 °F (5 to 8 °C) and average August temperatures ranging from 70 to 73 °F (21 to 23 °C). The climate becomes more severe in the foothills and mountains as elevation increases; above 6,000 feet (1,800 metres) it is cold, and snow lies on the summits for six months. The highest rainfall in Georgia occurs at Batumi, where an average 62 inches (1,600 mm) are recorded annually. Subtropical vegetation prevails in the lowland areas, and coniferous forests, scrub, and alpine meadows predominate on the mountain slopes.

The population includes Georgians, Russians, Armenians, and the Ajars themselves, a Georgian population Islamicized under Turkish rule. Although the Ajars are not a nationality distinct from other Georgians, they do represent a distinctive cultural segment of the Georgian homeland. Of the total population, less than one-half is urban and two-thirds live in the coastal lowlands and foothills.

Subtropical crops, which form the basis of the republic’s economy, include tea, citrus fruits, and avocados, tung trees (for oil), eucalyptus trees (camphor oil), and bamboo. Tobacco is grown in the higher areas, in which livestock raising is also important. Industrial development is concentrated around Batumi, the terminus of a pipeline from Baku on the Caspian Sea. Industrial activity includes oil refining, shipping and shipbuilding, food processing, light manufacturing, and the production of wine, plywood, furniture, and chemical pharmaceuticals. The republic is linked with the rest of Georgia by a road over the Goderdzi Pass in the Arsiyan Mountains and by the Transcaucasian Railway, which runs north along the coast from Batumi, then eastward. Ajaria has air services from Batumi to Tbilisi, Georgia; Moscow; and other cities.
