Such changes reflect primarily the changing structure of the economy and the successive advances that have been made in agricultural technology. 

Crop Losses to Pests and Changes in Agricultural Technologies... 

Unfortunately, there are few if any studies that adequately address this important question. Vast changes in agricultural technologies have occurred over the last 20 yr, especially in the area of biotechnology in crops and animals. Yet, in this area federal R D spending may have played a modest role that largely followed the massive amounts of venture capital that flowed into the biotech sector. 

Increasing globalisation leads to reduced consumer confidence in economic and social welfare, but the public is also extremely worried about the long-term effects of genetically modified food products and about other controversial technological changes in agriculture.

The mature Haber-Bosch technology is unlikely to change substantiaHy in the foreseeable future. The centers for commercial ammonia production may, however, relocate to sites where large quantities of natural gas are flared from cmde oil production, eg, Saudi Arabia or Venezuela. Relocation would not offset the problems for agriculture of high transportation and storage costs for ammonia production and distribution. Whereas the development of improved lower temperature and pressure catalysts is feasible, none is on the horizon as of this writing.
