Ppt World Food Supply And Demand For The Next Half Century Some Across 57 global food security projection and quantitative scenario studies that have been published in the past two decades, the total global food demand is expected to rise from 35% to 56%. Feeding 10 billion people sustainably by 2050, then, requires closing three gaps: an 11 gigaton ghg mitigation gap between expected agricultural emissions in 2050 and the target level needed to hold global warming below 2 o c (3.6°f), the level necessary for preventing the worst climate impacts. The move to a uniform growth scenario causes a much larger decline in food demand growth (from 102 percent to 78 percent) than that in food supply (from 112 to 104 percent). the resulting gap between supply and demand of 13.9 percent in log difference terms would lead to a price decline of 12.0 percent.

Some of the current and projected food demand arises from over consumption of food with growing health consequences in both the developed and some segments of society in the developing world. global estimates suggest 1.4 billion adults, 20 and older, are overweight, compared to 1.0 billion undernourished ( who, 2008 ). The belief that new technologies alone will suffice to maintain the world’s population–food supply balance indefinitely is as baseless as the belief that we can maintain it over the next half century without increasing the use of mineral fertilizers. technological optimism and ecological pessimism are both misguided.
