The Changma River, in north-central China, was dammed in 2002 to provide a reservoir and irrigation to resource-poor areas of Gansu Province. The project aimed to increase production of food grains and commodity crops and to alleviate poverty for some 200,000 poor farmers living in the region. Though 159 households were involuntarily relocated to accommodate the dam, the per-capita net income of communities around it has risen since it was constructed.
