Initiated in 2003, the NRR is a grassroots network of development projects which unites intellectuals, students and organizations to experiment with different models of agricultural and rural development in China. As an alternative to agricultural industrialization, the NRR favors the cooperation of smallholder farmers, local knowledge and agro-ecology for sustainable agricultural development. In order to understand the NRR's institutional characteristics, functioning and impact, we conducted a survey in Sancha village to collect data on smallholder farmers' socio-economic behavior and performed three in-depth NRR case studies. Our empirical analysis suggests that the NRR has promoted the development of organic farming in the village. Social activities are cost-effective for social network building where organic farming is diffused rapidly. Nevertheless, without sufficient, ongoing technical training, farmers newly converted to organic farming tend to overuse nitrogen and lose their environmental advantage in rice production. To improve the performance of smallholder farmers, participatory social learning appears useful but limited because smallholder farmers are interested in economic performance rather than environmental protection. On basis of these results, we recommend a state-civil society partnership which combines the government's agricultural extension services and bottom-up rural reconstruction for the commonobjective of sustainable agriculture in China.
