摘要: An analysis of the patterns of technology adoption by upland rice farmers in southern Yunnan and of the impact of technologies was conducted using farm–household data collected during 2005. The technologies considered were improved upland rice varieties and terraces. The results indicate that these technologies are now spreading in upland areas. Farmers who have adopted both technology components have been able to increase the upland rice yield substantially. Income from rice production was similarly found to be higher for adopters than for nonadopters. In addition, there was evidence that increased rice yield helped reduce the pressure from intensifying food production in these fragile uplands because farmers were able to meet their food needs from smaller areas. Implications of these findings for sustainable development of uplands in Yunnan and in countries in the region are drawn.
