For decades, cotton production has been the main economic activity in Uzbekistan -- and, to a lesser extent, in Tajikistan and Turkmenistan. But the sharp decline in world prices for raw cotton fiber is now posing a considerable economic challenge for the Central Asian states. The International Crisis Group, a nongovernmental organization focused on conflict prevention, warns in a new report that continued reliance on cotton will pose social, political, and environmental risks in the region. The report says cotton economies lead to forced labor, environmental waste, and the potential for social unrest.
