There are approximately 870 million undernourished people in the world today. Many children in poorer countries are underweight and do not get enough food to be healthy and active.
Three-quarters of all hungry people live in rural areas, mainly in the villages of Asia and Africa. Most of these people depend on agriculture for their food. They rarely have other sources of income or employment. As a result, they may be forced to live on one quarter of the recommended calorie intake and a small amount of water each day.
If enough rain does not fall at the right time of year, crops will not grow well and there will be little grass for livestock. However, rainfall is not the only factor contributing to hunger.
