Population, nutrition and agriculture

Original Paper

Abstract

The human carrying capacity of the world or a country is considered as a function of food consumption per capita. A method of assessing carrying capacity is described, and it is shown that the world’s population currently exceeds the global carrying capacity, that the population of the less-developed countries (LDCs) exceeds their carrying capacity, and that this situation cannot be expected to change more than marginally in the period up to 2050. It is also shown that a major increase in the global consumption of nitrogen fertilizer will be necessary if world crop production per capita is to be maintained at the current inadequate level.
