SWALLOWS flit over the paddy field where frogs croak and a traditional Southern Chinese rural scenario that Chen Guanghui is doing his best to restore. ＂The setting is, in fact, of ecological significance, as swallows, frogs and loaches protect the rice by eating pests,＂ Chen said. ＂But our de- pendence on pesticide has destroyed this ecological balance.＂
Through the three-dimensional organic agricultural system he devised, Chen has motivated tea growers to minimize their use of chemical pesticides.
