Abstract
For . agriculture to continue along a sustainable path of economic develop-
ment, further production increases must be generated by technologies that are
both profitable and more environmentally benign. In this context, we assess the
role of these “green” or sustainable technologies in steering agriculture along a
more sustainable path. However, the lack of markets for the environmental
attributes associated with green technologies can limit their development. In
addition, simply making a technology available does not mean it will be adopt-
ed. Experience with green technologies such as conservation tillage, integrated
pest management, enhanced nutrient management, and precision agriculture
demonstrates that even when technologies are profitable, barriers to adopting
new practices can limit their effectiveness.
