摘要：Information on the life-cycle environmental impacts of agricultural production is often
limited. As demands grow for increasing agricultural output while reducing its negative
environmental impacts, both existing and novel data sources can be leveraged to provide
more information to producers, consumers, scientists and policy makers. We review the
components and organization of an agroecological sensor web that integrates remote
sensing technologies and in situ sensors with models in order to provide decision
makers with effective management options at useful spatial and temporal scales for
making more informed decisions about agricultural productivity while reducing
environmental burdens. Several components of the system are already in place, but by
increasing the extent and accessibility of information, decision makers will have the
opportunity to enhance food security and environmental quality. Potential roadblocks to
implementation include farmer acceptance, data transparency and technology deployment.
