ILRI models project that average protein demand for meat, including beef, sheep, goat, poultry and pork, across the globe will increase by 16 per cent per person and 39 per cent in total between the year 2020 and the year 2050 if trends in income and population continue along a mid-range trajectory. The fastest per person rates of projected increase were 44 per cent in Africa and 47 per cent in South America.
