Borders in the Fergana Valley in Soviet times bore little relevance to everyday life. Hence, later demarcation of its international borders has been complex. As a result, today large areas of land officially claimed by one state in the Fergana Valley are being farmed by citizens of the other states, an example of which lies along the Batken-Isfara (Kyrgyzstan-Tajikistan) border, where over 1300 hectares of land are disputed.
