Trends in population, developed and developing countries, 1750-2050 (estimates and projections)
Each day 200,000 more people are added to the world food demand. The world’s human population has increased near fourfold in the past 100 years (UN population Division, 2007); it is projected to increase from 6.7 billion (2006) to 9.2 billion by 2050, as shown in Figure 4 (UN Population Division, 2007). It took only 12 years for the last billion to be added, a net increase of nearly 230,000 new people each day, who will need housing, food and other natural resources. The largest population increase is projected to occur in Asia, particularly in China, India and Southeast Asia, accounting for about 60% and more of the world’s population by 2050 (UN Population Division, 2007). The rate of population growth, however, is still relatively high in Central America, and highest in Central and part of Western Africa. In relative numbers, Africa will experience the most rapid growth, over 70% faster than in Asia (annual growth of 2.4% versus 1.4% in Asia, compared to the global average of 1.3% and only 0.3% in many industrialized countries) (UN Population Division, 2007). In sub-Saharan Africa, the population is projected to increase from about 770 million to nearly 1.7 billion by 2050.
