Price of Oil and Food Soars.

The price of crude oil has now hit above $112 a barrel, which is more than five times that of five or six years ago, while the price of rice has risen by up to 70% from last year. It is debatable what exactly is the reason for such a huge hike in oil prices, but the general costs of extracting it, including exploration, have increased markedly, as it becomes ever more difficult to secure enough oil to meet world demand of 30 billion barrels a year for it. All the major oil companies have needed to invest substantially in infrastructure and are angling in more costly regions e.g. in deep-sea locations and potentially the Arctic.

A new elephant field has not been found since the early 1980's, and it is thought that once the Middle East giants, especially Ghawar in Saudi, begin to decline, we are all in big trouble, living in a world utterly dependent on cheap oil. I doubt the price of conventional crude oil will ever come down, and unconventional sources even if fully exploited, will also become increasingly expensive to produce from, in the wake of the increasing costs of other resources of energy and water required to get oil from heavy crude and bitumen - for example in tar-sands. To exploit significant amounts of such resources, and if coal-to-liquids etc. are to be employed appreciably, will need massive new engineering, and I question just how much can be brought on-line within the crucial next decade, during which peak-oil and its consequences must be met head-on.

Some estimates of total conventional plus unconventional oil amount to 3.7 trillion barrels, but success in supplying the annual 30 billion barrels currently demanded, let alone satisfying projected requirements in a model of untrammelled economic growth, depends not on how big the resource is, but how quickly it can be extracted and processed. Providing enough platinum to fabricate hundreds of millions of fuel cells poses a similar dilemma, since while there is more than enough of the metal in the Earth per se, producing pure Pt is a very exacting process which limits its rate of production dramatically. A shortfall in oil, which I expect will prove the reality, means a deep decline in the world's transportation and a relocalisation of societies into small communities. It is indeed the issue of keeping transportation running, as conventional oil supplies fail to meet our urging for them, that is the linchpin of the human mechanism, and if this fails in an abrupt and unmanaged way, so will civilization.

Rice is the staple food for half the world's population of 6.7 billion; however, the price of rice has increased by up to 70% during the past year. In part, this is blamed on poor harvests in consequence of "extreme weather", rising populations and hence demand for food in countries that import rice from world markets, an expectation that things can only get worse leading to hoarding, and depleting stockpiles and insufficient investment in agriculture. In fact, the increasing cost of rice is but one example of an increase in world food prices overall. In an effort to protect their own internal food-provision and to curb inflation, main rice-producing nations, e.g. India, China and Vietnam, have imposed restrictions on exports. On the other side of the coin, net rice-importers such as Bangladesh, Afghanistan and the Philippines are suffering the consequences of an unstable and costly supply.

Rapid economic development in Asia has led to a more prosperous and more numerous middle class who eat more food, while land formerly used to grow rice is now used to host new housing developments, factories and in some regions, golf courses. The biofuels market has grown since 2006 providing a greater incentive for farmers to grow corn for ethanol than to produce rice, bringing global stockpiles to their lowest level for twenty years. Particular local factors have also contributed to the situation, such as the cyclone which destroyed much of Bangladesh's autumn rice crop last November, a total of almost one million tonnes. As a consequence of this, the country has imported 2.4 million tonnes of rice to avert a famine. Vietnamese rice-crops have also have suffered from a combination of adverse weather and infestations of pests.

There are fears that food-rioting may result, causing unrest and destabilisation across Asia and Africa, where half the world lives. The escalating price of rice and a weak US dollar has strained food-aid programmes, for example to feed the Myanmar refuges who are heading in large numbers toward the Thai border. I am reminded of the Hubbert analysis I have alluded to recently, that rather than the world population rising unchecked to 9 billion by 2050, it will instead peak at around 7.3 billion, somewhere close to the year 2025, and then decline to around 2.5 billion by the end of this century (2100). Possibly, we are beginning to glimpse the mechanisms by which this may occur, and that the greatest incidence of a population "die-off" will occur in the developing nations, i.e. Africa, Asia and South America, where the population growth has been greatest, especially during the past century.

Since most of this growth has been fed by mechanised agriculture, which only exists as underpinned by cheap oil and natural gas, it follows that the present number of people on Earth cannot be maintained during the imminent oil-dearth era. What other conclusion can be drawn?
