Explanation:

    The configuration of the Central Asian economy (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) is largely linked to the primary sector, particularly in agriculture, livestock and mineral extraction.

    In agricultural production, the cultivation of cotton and fruits stands out. For agricultural development intensive irrigation techniques need to be employed to ensure productivity and domestic food supply. Irrigation canals were built with the waters of the tributary rivers of the Aral Sea to supply the crops located near the course of their tributaries.
