What more demand for meat means for the future

Here is an excerpt from We Will Reap What We Sow, the book I published in May 2012. The recent difficult climatic conditions for agriculture and their impact of agricultural markets have made the issue quite relevant. Here it is then:

As the economy in emerging countries is improving, their population becomes wealthier. Just as it happened in Western countries during the 20th century, the increase in wealth translates into dietary changes. The consumption of animal protein, especially the consumption of meat, increases.

To realize what the consequences of a higher consumption of meat might be, it is interesting to make calculations for China. When 1.5 billion people eat on average one more kg of chicken meat per person, world production needs to increase by about 750 million chickens. That represents about 2% of the world’s production. Similarly, when each Chinese consumes on average one more kg of pork, the world must produce 15 million more pigs. That number represents 1.5% of the world pig production. For beef, an increase of consumption of one kg per capita per year means the need for a production of 2.4% higher than today.

Meat consumption in China has already passed the milestone of 50 kg per capita per year, and projections indicate that it should reach 80 kg per capita per year in 2030. Clearly, consumption will increase by much more than just one kg.

An increase of 10 kg of chicken meat per capita per year in China means that the world’s chicken production would have to increase by 20% to meet the new demand! This represents almost the entire US chicken production volume, and more than Brazilian production. In the case of pork, an increase of consumption of 10 kg per capita means that the world’s pig production would have to increase by 15%. That is five times the current pig production of Iowa, USA. That is 60% of the EU production. For beef, the world’s production would have to increase by 24% to meet an increase of 10 kg per capita per year! This number also represents about 125% of the current total US beef production.

Different animal productions have different feed conversion ratios (FCR). The FCR is the quantity of feed needed to produce 1 kg of meat. For chicken meat, the FCR is of 1.8. For pig meat, the FCR is about 3. For beef, depending on the proportion of grass in the cattle’s diet, the amount of grain used to produce 1 kg of beef varies. With an average FCR of 3 for the various types of meat productions, an increase of meat consumption of 30 kg in China would result in the need to produce three times 30 kg times 1.5 billion. Depending on the consumption of which type of meat will grow the fastest, the need for feed, excluding grass, would vary between 100 and 150 million tons.

The world’s second largest population, the Indian population, is still largely vegetarian. Although India is among the countries with the lowest meat consumption, with less than 4 kg per capita per year, Indians are gradually changing their eating habits. Meat consumption is increasing in India, too, but not in proportions as dramatic as in China. Nonetheless, with a growing population, any incremental meat consumption will have physical consequences. Some simple math can show the magnitude of the higher demand for meat.

Between 2010 and 2050, the world’s population will increase by 2.2 billion, from 6.8 billion to nine billion. If everything stays equal, the consumption would increase by about a third (2.2/6.8). According to the FAO, the average consumption of meat per capita in the world in 2010 was of about 47 kg. The population growth alone would represent a meat consumption increase of 2.2 billion times 47, or 103 million tons. This number represents about a third of the 2010 meat consumption.

In the example of China mentioned earlier, the predicted increase of 30 kg per person represented an increase in meat consumption of 45 million tons.

Even if the world average meat consumption per capita remained stable between 2010 and 2050, the need for additional meat production would be of 2.3 (103/45) times the numbers in the China example. This represents an additional need for animal feed, excluding grass, of between 230 and 345 million tons compared with 2010.

The situation becomes even more interesting when the average consumption per capita increases. For every 10 kg increase of individual consumption, the need for additional meat production increases by nine billion times 10 kg, or 90 million tons of meat. For each 10 kg increase of average meat consumption, an additional volume of 600 to 900 million tons of animal feed is necessary. The following table presents the effect of the population increase to nine billion people and its meat consumption on production volumes.

Average individual meat consumption increase from 2010 (kg/capita/year)







Average individual meat consumption(kg/capita/year)







Total meat consumption(million tons)







Total meat consumption increase from 2010 (million tons)







Percentage of increase from 2010







An average meat consumption of 97 kg per capita per year would be about the current average of developed countries. If the average meat consumption per capita per year in the world were to meet such a number, meat production would have to almost triple from 2010 volumes.

Most of the gloomy scenarios about the challenge of feeding the world are based on the assumption that the diet model would have to be the Western diet, and in particular the American diet. This is far from certain. Actually, it probably will not be the case. As the world’s population increases, one of the sensitive issues, especially in the overfed world, will be what to eat and how much of it. Higher food prices will also force people to indulge less. It is important to understand the difference between nutritional needs and consumer desires. Today, the world produces enough calories and protein to meet the actual nutritional needs of nine billion people. If the nine billion people expected for 2050 all want to have a Western diet, the amount of calories needed would be equivalent to the nutritional calorie needs of 17.5 billion people.

It would be normal to expect feed conversion efficiency to improve in the future. Nonetheless, the production for animal feed would then increase with 3,000 to 4,500 million tons above the volumes necessary in 2010. Since a third of grain production goes to animal feed, a tripling of meat production means that grain production would have to double, just because of the desire for more meat.

Clearly, the challenge of feeding the world will depend increasingly on meeting the demand for meat. The challenge for producers of agricultural commodities will be to keep up with the demand for animal feed. As demand for meat increases, there is no doubt that more and more questions will arise about how much meat the world can afford to eat. The world food situation will depend on how much meat people want to eat, not on calorie count.

How much meat should we eat?…
