Abstract

|
|
The worlds population is expected to grow from just under six billion in 1997 to over eight billion in 2025 and most of this growth will occur in developing countries. This is alarming because already some regions of Sub-Saharan Africa and S. Asia show continued growth in population size and stagnation in nutritional improvement, indeed, even an increase in total number of malnourished under 5 years children.
Population growth places increased demands on the already challenged adequacy of the world food supply. The Sub-committee on Nutrition of the United Nations estimates that world-wide. food grain needs to maintain consumption levels and meet emergency needs will double over the next decade. The available global food-aid deliveries, however, have declined while nutritional emergencies have risen shifting emphasis to meeting emergency needs´ at the expense of development projects. This shift reduces household food security for many in. reaching their nutritional requirements.
Urbanization, occurring rapidly in less developed countries, is disrupting family structures and straining the already limited public resources available to migrating populations. Removed from land for growing food, the urban migration without growth in work available with adequate pay shows national development progress and increases poverty and dependency. Poverty reduction strategies are vital if global health and nutritional status are to improve in the next century.
In addition, the world is experiencing a demographic transition. Life expectancy is increasing while infant mortality is on the decline. The result is an aging of the worlds population. This changing demographic profile reduces the dependency ratio and adds new dimensions to global nutrition challenges. Thus, rural to urban migration, AIDS-related deaths of young adults, as well as decreasing family size place increased burden on society for care of elderly and on nutrition scientists to better assess the needs of the aged and programs for assuring that those needs are met.
Natural disasters and famines, for the most part, are not major problem as in the past due to improvements in emergency response to crisis, as well as in ration planning, distribution and monitoring. However, man-made emergencies are on the rise. Civil disruption and political instability dislocates people and their ability to produce food. This pr()hlem has plaqued Africa in recent days and rendered masses of people inaccessible to humanitarian assistance. Mortality rates have soared in makeshift camps due to security and political events interfering with delivery of aid.
The 21" century challenge for the nutrition community is to eliminate deficiency disease while pre-venting diet-related chronic degenerative diseases and obesity, and to do this within the context of increasing limited resource commitments to development.
