This paper examines the impacts of agricultural technology changes on farmers' relationship with nature and their environment. Based on a field study in Bena Irrigation Area in South Amanuban Sub-District, Timor, East Nusa Tenggara, Indonesia, this paper analyses how the introduction of new technologies in agriculture by the Government of Indonesia in these last 30 years has changed the farmer's pattern of cultivation, their views about nature and environment, and the ways they link their agricultural activities with social life. This study found that many of the traditional steps in the cultivation cycle have disappeared or been replaced by new technologies, resulting in profound changes in their views and attitude to nature, the environment and social relationships. Impacts on agriculture productivity are still debatable. However, this study argues that some supporting policies are necessary to make the use of new agricultural technologies give the best benefit for the welfare of farmers and the preservation of nature.
