The subtropics are climate zones typical of parts of the Earth immediately north and south of the tropical zone, which is bounded by the Tropic of Cancer and the Tropic of Capricorn, at latitudes 23.5°N and 23.5°S. Subtropical regions are the climatic regions typically found adjacent to the tropics, usually between 23.5 and 40 degrees of latitude in both hemispheres, although such climates may occur at greater latitudes, or within the tropics themselves.
Suitability for economic use . The tropical zone due to the aridity of the climate is not suitable for economic activities. In the semi-desert regions, only a few branches of livestock production have developed on a large scale. Potential for crop production is limited. The climate of the subtropics has all the conditions for the development of agriculture, gardening and recreational facilities. The famous large resort centers of the Mediterranean, the North American coast and South-East Asia are located in the subtropical belt and receive an enormous number of tourists every year.
