Technical Abstract: Intensive high input/output modes of agricultural production can have numerous adverse environmental impacts, such as gaseous emissions that contribute to global climate changes and pollution of land and water. This paper begins with a brief description of the evolution and typology of global, industrial agricultural systems, followed by an overview of the principal environmental impact domains at various scales. It then focuses on the main biophysical and socioeconomic determinants of environmental outcomes that are associated with industrial agriculture with a focus on nutrient management in crop and animal production. The paper proceeds with a discussion of technology and policy options for improving environmental performance. It concludes with a call for more integrated development approaches that improve the capacity of policy makers, extension programs, farmers, future land mangers and agribusiness to make integrated nutrient management decisions that consider all components of an agricultural system and associated environmental impacts.
