Yanchi, Ningxia - Lines of "green wall" are built along the desert district in Yanchi county, Ningxia Hui autonomous region to defend against desertification, on March 31, 2010. The "green wall" environmentally-friendly project has effectively prevented further expansion of desert, and in combination with manual measures including irrigation, cultivation, etc, the green-plant coverage in Gaosha town area has exceeded 3 million square acres, turning the previous 1.2 million-acre desert area into a green one.
