Furthermore, workers in greenhouses are employed in a much more comfortable and hospitable environment than field workers and as such the pressure to mechanize is less intense. Looking to the future, harvesting techniques will continue to attract substantial interest and investment in determining if the state-of-the-art technologies (machine vision, robotics, software engineering, GPS and GIS) can be successfully applied to harvesting machines particularly in relation to selective harvesting and the harvesting of delicate produce for the fresh market.
Because the direct effects of mechanization on yields are small, however, any effect of subsidies on agricultural output must be an indirect one that arises from the cost reduction made possible by machines. But when mechanization is not spontaneously driven by some form of labor scarcity, the impact on production costs is not large; the output effects of subsidies therefore cannot be large either. When mechanization is caused by subsidies, reductions in the agricultural work force can be substantial.
