The Big Three of the 21st Century--Food, Energy and Water

Here at the beginning of the 21st century, the challenges are clear: the growing population is stressing the Earth's resources to the breaking point. The "big three" are Food, Energy and Water--whose initials ominously spell FEW. Looming shortages make human misery more likely as time passes without finding solutions. Will the 21st Century be known as the Century of Scarcity? Or will we find new technical, political and economic approaches to free humanity from want and discontent?

An update on the arable land situation in China

Following up on a previous blog (2 1/2 years ago!)

The amount of arable land in China is marginal with respect to feeding its population, and that land is shrinking. Here is a good update (which ends by recommending that we all invest in farmland, as its price is sure to rise):

A brief summary: Chinese arable land has probably decreased below the 120 million hectares thought necessary for agricultural self-sufficiency; that's about .08 hectares per person; China is probably a net food importer, and will surely become one in a couple of years; China is attempting to compensate by buying land overseas, particularly in Africa.

In his book "Endless Appetites," Alan Bjerga points out one of the problems of foreign ownership of farmland: how local people will react if they experience a food shortage while food is being exported. But here's another issue: at least some of the "available uncultivated land" in Africa is RAIN FOREST. There is surely a link between tropical deforestation and the rising levels of CO2 in the atmosphere. So while China must surely pursue many avenues to feed its still-growing population, we must also keep track of how their overseas efforts could effect the global environment.
