Learning from Dogs

Dogs are integrous animals. We have much to learn from them.

An organisation that deserves wide support.

Read it!

My copy of Lester Brown’s book World on the Edge arrived on Tuesday and already it’s opening my eyes big time.  I do recommend that you think about purchasing the book, or you may download the entire book for free – details here.

Regular visitors to Learning from Dogs will remember that there was mention in a recent Post, Group Human Insanity about Lester Brown’s new book.  I have subscribed to regular updates from the EPI and recently received the following; it’s worth reproducing in full, with the permission of the EPI.

Restoring Food Security for All
Takes Action on Many Fronts

By Lester R. Brown

Today there are three sources of growing demand for food: population growth; rising affluence and the associated jump in meat, milk, and egg consumption; and the use of grain to produce fuel for cars.

Population growth is as old as agriculture itself. But the world is now adding close to 80 million people per year. Even worse, the overwhelming majority of these people are being added in countries where cropland is scarce, soils are eroding, and irrigation wells are going dry.

Even as we are multiplying in number, some 3 billion of us are trying to move up the food chain, consuming more grain-intensive livestock products. As incomes rise, annual grain consumption per person climbs from less than 400 pounds, as in India today, to roughly 1,600 pounds, as among those living high on the food chain in the United States, where diets tend to be heavy with meat and dairy products.

When the United States attempted to reduce its oil insecurity by converting grain into ethanol, the growth in world grain demand, traditionally around 20 million tons per year, suddenly jumped to over 50 million tons in 2007. Roughly 119 million tons of the 2009 U.S. grain harvest of 416 million tons went to ethanol distilleries, an amount that exceeds the grain harvests of Canada and Australia combined. This massive ethanol distillery investment in the United States launched an epic competition between cars and people for grain.

On the supply side of the food equation, several trends are making it more difficult to expand production rapidly enough to keep up with demand. These include soil erosion, aquifer depletion, more frequent crop-shrinking heat waves, melting ice sheets, melting mountain glaciers, and the diversion of irrigation water to cities.

Farmers are also losing cropland to nonfarm uses. Cars compete with people not only for the grain supply but also for the cropland itself. The United States, for example, has paved an area for cars larger than the state of Georgia. Every five cars added to the U.S. fleet means another acre of land will be paved over—the equivalent of a football field.

The implications for China of this relationship between cars and cropland are startling. In 2009, for the first time, more cars were sold in China than in the United States. If China were to reach the U.S. ownership rate of three cars for every four people, it would have over a billion cars, more than the entire world has today. The land that would have to be paved to accommodate these cars would be two thirds the area China currently has in rice.

This pressure on cropland worldwide is running up against increased demand for soybeans, which are the key to expanding the production of meat, milk, and eggs. Adding soybean meal to livestock and poultry feed sharply boosts the efficiency with which grain is converted into animal protein. This is why world soybean use climbed from 17 million tons in 1950 to 252 million tons in 2010, a 15-fold jump.

Nowhere is the soaring demand for soybeans more evident than in China, where the crop originated. As recently as 1995, China produced 14 million tons of soybeans and consumed 14 million tons. In 2010, it still produced 14 million tons, but it consumed a staggering 64 million tons. In fact, over half of the world’s soybean exports now go to China.

Demand is climbing, but since scientists have failed to increase yields rapidly, the world gets more soybeans largely by planting more soybeans. The soybean is devouring land in the United States, Brazil, and Argentina, which together account for four fifths of world soybean production and 90 percent of exports.

Ensuring future food security was once the exclusive responsibility of the ministry of agriculture, but this is changing. The minister of agriculture alone, no matter how competent, can no longer be expected to secure food supplies. Indeed, efforts by the minister of health and family planning to lower human fertility may have a greater effect on future food security than efforts in the ministry of agriculture to raise land fertility.

Similarly, if ministries of energy cannot quickly cut carbon emissions, the world will face crop-shrinking heat waves that can massively and unpredictably reduce harvests. Saving the mountain glaciers whose ice melt irrigates much of the cropland in China and India during the dry season is the responsibility of the ministry of energy, not solely the ministry of agriculture.

If the ministries of forestry and agriculture cannot work together to restore tree cover and reduce floods and soil erosion, grain harvests will shrink not only in smaller countries like Haiti and Mongolia, as they are doing, but also in larger countries, such as Russia and Argentina—both wheat exporters.

And where water shortages restrict food output, it will be up to ministries of water resources to do everything possible to raise national water productivity. With water, as with energy, the principal potential now is in increasing efficiency, not expanding supply.

In a world where cropland is scarce and becoming more so, decisions made in ministries of transportation on whether to develop land-consuming, auto-centered transport systems or more-diversified systems that are much less land-intensive will directly affect world food security.

In the end, it is up to ministries of finance to reallocate resources in a way that recognizes the new threats to security posed by agriculture’s deteriorating natural support systems, continuing population growth, human-driven climate change, and spreading water shortages. Since many ministries of government are involved, it is the head of state who must redefine security.

At the international level, we need to address the threat posed by growing climate volatility and the associated rise in food price volatility. The tripling of wheat, rice, corn, and soybean prices between 2007 and 2008 put enormous stresses on governments and low-income consumers. This price volatility also affects producers, since price uncertainty discourages investment by farmers.

In this unstable situation, a new mechanism to stabilize world grain prices is needed—in effect, a World Food Bank (WFB). This body would establish a support price and a ceiling price for wheat, rice, and corn. The WFB would buy grain when prices fell to the support level and return it to the market when prices reached the ceiling level, thus moderating price fluctuations in a way that would benefit both consumers and producers.

One simple way to improve food security is for the United States to eliminate the fuel ethanol subsidy and abolish the mandates that are driving the conversion of grain into fuel. This would help stabilize grain prices and buy some time in which to reverse the environmental and demographic trends that are undermining our future. It would also help relax the political tensions over food security that have emerged within importing countries.

And finally, we all have a role to play as individuals. Whether we decide to bike, bus, or drive to work will affect carbon emissions, climate change, and food security. The size of the car we drive to the supermarket and its effect on climate may indirectly affect the size of the bill at the supermarket checkout counter. At the family level, we need to hold the line at two children. And if we are living high on the food chain, we can eat less grain-intensive livestock products, improving our health while helping to stabilize climate. Food security is something in which we all have a stake—and a responsibility.

Not much I can add to that!

UPDATE:  Just a few hours after completing the Post, I saw this on the BBC News website.

The global consumption of fish has hit a record high, reaching an average of 17kg per person, a UN report has shown.

Fisheries and aquaculture supplied the world with about 145m tonnes in 2009, providing about 16% of the population’s animal protein intake.

The findings published by the Food and Agriculture Organization (FAO) also stressed that the status of global fish stocks had not improved.

It said that about 32% were overexploited, depleted or recovering.

“That there has been no improvement in the status of stocks is a matter of great concern,” said Richard Grainger, one of the report’s authors and FAO senior fish expert.
