Policy makers in the People's Republic of China have been experimenting with new approaches to environmental management, resulting in a wide array of policy and program innovations under the broad heading of eco-compensation. Many of these are market-based instruments, particularly payments for ecological services—-currently an emerging policy debate regarding the extent to which beneficiaries should pay, and the providers should be compensated—-for the provision of natural resources and environmental services to promote sustainable, balanced growth. These proceedings are a collection of papers presented at the International Conference on Payments for Ecological Services convened in Ningxia Hui Autonomous Region in September 2009 to support eco-compensation programs in the country.
