One of the questions I am most often asked is, “How many peo-ple can the earth support?” I answer with another question: “Atwhat level of food consumption?” Using round numbers, at theU.S. level of 800 kilograms of grain per person annually for food and feed, the 2-billion-ton annual world harvest of grain would support 2.5 billion people. At the Italian level of consumption of close to 400 kilograms, the current harvest would support 5 billion people. At the 200 kilograms of grain consumed by the average Indian, it would support a population of 10 billion.
As part of the Crisis Policy Forum, the HotSpring collaborative innovation initiative is now planning an effort to tackle the problem of food supply management and chronic food and water scarcity in Africa. The lessons from this experiment in collaborative research will be applicable in many cases to other situations around the world, and we are open to spurring dialogue in those areas as outgrowths of this ongoing discussion.
At the World Economic Forum at Davos, Switzerland, a range of ideas from international disease relief, healthcare, security, climate change, extreme poverty, and the responsibility of market incentives, took the discussions in a new direction. Fmr. US vice-president Al Gore spoke of the need for a “marriage” of policy regarding extreme poverty and the climate crisis.
If you think you are spending more each week at the supermarket, you may be right. The escalating share of the U.S. grain harvest going to ethanol distilleries is driving up food prices worldwide. Corn prices have doubled over the last year, wheat futures are trading at their highest level in 10 years, and rice prices are rising too. In addition, soybean futures have risen by half.
The Elders is a humanitarian initiative led by South African archibishop Desmond Tutu and former South African pres. Nelson Mandela, designed to bring the African “village elders” concept to the global village, in an effort to defuse flashpoint crisis situations and speed responsible policy-making. Its foundations are the basic principles of human rights and the experience and credibility of the group’s emissaries.
As land and water become scarce and as competition for these vital resources intensifies, we can expect mounting social tensions within societies, particularly between those who are poor and dispossessed and those who are wealthy, as well as among ethnic and religious groups. Population growth brings with it a steady shrinkage of life-supporting resources per person. That decline, which is threatening to drop the living standards of more and more people below survival level, could lead to unmanageable social tensions that will translate into broad-based conflicts.
On March 16, 2003, some 10,000 participants [met] in Japan for the third World Water Forum to discuss the world water prospect. Although they [would] be officially focusing on water scarcity, they [would also] indirectly be focusing on food scarcity because 70 percent of the water we divert from rivers or pump from underground is used for irrigation.
As world water demand has tripled over the last half-century, it has exceeded the sustainable yield of aquifers in scores of countries, leading to falling water tables. In effect, governments are satisfying the growing demand for food by overpumping groundwater, a measure that virtually assures a drop in food production when the aquifer is depleted. Knowingly or not, governments are creating a “food bubble” economy.
