Descripción
This paper discusses the natural resource implications of the latest FAO food and agriculture baseline projections to 2050 (FAO, 2006a). These projections offer a comprehensive (food and feed demand, including all foreseeable diet changes, trade and production) and consistent picture of the food and agricultural situation in 2030 and 2050. The main purpose of this paper is to provide an indication of the additional demands on natural resources derived from the crop production levels in 2 030 and 2050 as foreseen in the FAO 2006 projections. It does not deal with additional demand for agricultural products used as feedstock in biofuel production or the impacts of climate change (these are dealt with in another paper, G. Fischer 2009, for this expert meeting), nor the additional production needed to eliminate (or to accelerate the elimination of) the remaining undernourishment in 2050. Growth in agricultural production will continue to slow down as a consequence of the s lowdown in population growth and of the fact that an ever increasing share of world population is reaching medium to high levels of food consumption. Nevertheless, agricultural production would still need to increase by 70 percent (nearly 100 percent in developing countries) by 2050 to cope with a 40 percent increase in world population and to raise average food consumption to 3130 kcal per person per day by 2050. This translates into an additional billion tonnes of cereals and 200 mil lion tonnes of meat to be produced annually by 2050 (as compared with production in 2005/07).
