Agricultural Commodities: Playing an Acknowledged Theme

If indeed the climate is warming, the amount of land in the extremes of North and South of continents will come into production. They will be growing more grains in heretofor unfarmable land in Alberta, Alaska, Siberia, Chile, New Zealand, etc.

Availablility of water irrigation is critical. Israelis "made the desert bloom" as we have done in the US in the San Joaquin valley, the Coachella Valley, Rio Grande Valley and others. The San Fernando Valley was desert before water was brought down from the north is the 20s and 30s. Humongus areas here in Texas are desert because we cannot move fresh (desalinated) water from the GOM 200 miles inland. There is really little if anything with the water delivery capability of the Central California Water Project or the Colorado River Project in the entire world.

Crop yields have grown considerably in the past 20 years.. Due both to use of fertilizer and genetic selection.

The urbanization factor in land use will mitigate itself as the tiime and cost of commuting become become unbearable for the vast majority of people who cannot handle the burden. People will resign themselves to living in European "stacked boxes". Perhaps some remote housing deveopments might even revert to farm land. Not a lot of people will commute daily from Tracy, Manteca, Gilroy and from Patterson, CA to San Jose any more.

It is the price of energy sources and human population grown which are the real limiting factors for the standard of living level around the world. Both have to be controlled to ensure adequate food supplies and quality of life for humans.
