 On the one hand, this increased labour cost is one factor that makes organic food more expensive.On the other hand, the increased need for labour may be seen as an "employment dividend" of organic farming, providing more jobs per unit area than conventional systems.The 2011 UNEP Green Economy Report suggests that "[a]n increase in investment in green agriculture is projected to lead to growth in employment of about 60 per cent compared with current levels" and that "green agriculture investments could create 47 million additional jobs compared with BAU2 over the next 40 years."
