Music in Sport and Exercise: An Update on Research and Application Submitted by: To a greater degree than in the original article, this article focuses on the applied aspects of music in sport and exercise. Moreover, it highlights some new research trends emanating not only from our own publications, but also from the work of other prominent researchers in the field.
Trends in the supply of vegetables per capita, by region, Source: This has raised fears that the world may not be able to grow enough food and other commodities to ensure that future populations are adequately fed.
However, the slowdown has occurred not because of shortages of land or water but rather because demand for agricultural products has also slowed. This is mainly because world population growth rates have been declining since the late s, and fairly high levels of food consumption per person are now being reached in many countries, beyond which further rises will be limited.
As a result, the growth in world demand for agricultural products is expected to fall from an average 2. In developing countries the slowdown will be more dramatic, from 3.
Global food shortages are unlikely, but serious problems already exist at national and local levels, and may worsen unless focused efforts are made.
The annual growth rate of world demand for cereals has declined from 2. Annual cereal use per person including animal feeds peaked in the mids at kg and has since fallen to kg. The decline is not a cause for alarm, it is largely the natural result of slower population growth and shifts in human diets and animal feeds.
During the s, however, the decline was accentuated by a number of temporary factors, including serious economic recessions in the transition countries and in some East and South-East Asian countries. The growth rate in the demand for cereals is expected to rise again to 1. In developing countries overall, cereal production is not expected to keep pace with demand.
This gap can be bridged by increased surpluses from traditional grain exporters, and by new exports from the transition countries, which are expected to shift from being net importers to being net exporters. Oil crops have seen the fastest increase in area of any crop sector, expanding by 75 million hectares between the mids and the end of the s, while cereal area fell by 28 million hectares over the same period.
Future per capita consumption of oil crops is expected to rise more rapidly than that of cereals. These crops will account for 45 out of every extra kilocalories added to average diets in developing countries between now and There are three main sources of growth in crop production: It has been suggested that growth in crop production may be approaching the ceiling of what is possible in respect of all three sources.
A detailed examination of production potentials does not support this view at the global level, although in some countries, and even in whole regions, serious problems already exist and could deepen.
Diets in developing countries are changing as incomes rise. The share of staples, such as cereals, roots and tubers, is declining, while that of meat, dairy products and oil crops is rising. Poultry consumption is predicted to grow the fastest.
Productivity improvements are likely to be a major source of growth. Milk yields should improve, while breeding and improved management should increase average carcass weights and off-take rates. This will allow increased production with lower growth in animal numbers, and a corresponding slowdown in the growth of environmental damage from grazing and animal wastes.
In developing countries, demand is predicted to grow faster than production, resulting in a growing trade deficit. In meat products this deficit will rise steeply, from 1. An increasing share of livestock production will probably come from industrial enterprises.Oct 11, · Check out our top Free Essays on Article Concerning Trends In Consumption Patterns to help you write your own Essay.
