Is low green­house gas emis­sion (GHG) agri­cul­ture pos­si­ble? Is it, in fact, desir­able?
In seek­ing answers to these two basic but extremely rel­e­vant ques­tions, this study
exam­ines cur­rent farm­ing prac­tices and incor­po­rates scientific data­bases from
long-​term field exper­i­ments as case stud­ies for low GHG agri­cul­ture. Fur­ther, the study
exam­ines the changes that will be needed for low green­house gas agri­cul­ture sys­tems
to become a real­ity. It also elu­ci­dates the adap­tive capac­ity of agro-​ecological farm­ing
sys­tem approaches, using organic sys­tem case stud­ies from the scientific lit­er­a­ture.
Each year, agri­cul­ture emits 10 to 12 per­cent of the total esti­mated GHG emis­sions,
some 5.1 to 6.1 Gt CO
2 equiv­a­lents per year. Smith, et al. (2007) and Bel­larby, et al. (2008)
have pro­posed mit­i­ga­tion options for GHG emis­sions, finding that both farm­ers and pol­icy–
mak­ers will face chal­lenges from the GHG-​related changes needed in agri­cul­ture. Areas
for improve­ment include increased use of no-​till crop­ping, agro-​forestry, and inte­grated
crop and ani­mal farm­ing, and decreased use of exter­nal inputs in food and agri­cul­ture. The
tech­niques offered by organic agri­cul­ture are valu­able for con­sid­er­a­tion in these efforts.
