The changes in the food supply over a period of almost 50 years in the three biggest economies in Asia were examined to estimate the change in the virtual phosphorus requirements in each country over time with regard to food consumption. While the overall food supply in the rapidly growing economies of India and China grew rapidly, there are some remarkable differences in the food supply in these two emerging giant economies over time. Having undergone rapid development in the late 1970s and 1980s, Japan’s food supply stabilized with the stagnation of the Japanese economy in the mid 1990s. The implications of the changes in the food supply of these three economies are discussed in terms of the phosphorus demand for producing food for these three countries using the concept of the virtual phosphorus. Future projections were made to create a likely case scenario for the virtual phosphorus requirements in these countries in the lead up to 2050 by extrapolation and by incorporating the latest population predictions.
