As a result, world grain production has fallen short of consumption in seven of the last eight years, dropping
world grain stocks to their lowest level in 34 years.
If such a drop were to occur today,
when grain stocks are seriously depleted, there would be panic in the world grain market.
But previous calls for people to eat less meat in order to help the environment, or
preserve grain stocks, have been highly controversial.
In a world with
limited grain stocks, a crop - shrinking heat wave in a major grain - producing region could lead to food shortages and political instability.
Overall, global agriculture can keep up with growing demand if the weather is favorable, but even the mildly poor 2010 growing season was enough to force a draw down in stockpiles of grain outside China, which sent
total grain stocks to very low levels.
Never modest in his pronouncements, he sees nothing short of a collapse of civilization if governments do not pay attention to disturbing overlapping planetary trends: plunging water tables, depleting and eroding soil, and
dwindling grain stocks, with global warming in the background quickening the slide.
Because the weedy forms are closely related to rice varieties that were never grown in the U.S., they probably arrived as contaminants
in grain stocks from Asia instead of evolving directly from the tropical japonica crops grown here.
A post from last fall
on grain stocks and food (in) security on the Big Picture Agriculture blog (at the time, the unrest was in Mozambique) has some helpful context on the mix of issues affecting food availability:
Thus any attempt to expand the world grain harvest enough to rebuild depleted world
grain stocks starts with reversing the decline in China.
With grain stocks at an all - time low, the world is only one poor harvest away from total chaos in world grain markets.
Global grain stocks are expected to surpass 500 million tonnes for the first time at the end of the 2016/17 season.
This comes at a time when
world grain stocks are at their lowest level in 30 years and when U.S. farmers are losing irrigation water to aquifer depletion and to cities.
World carry - over
grain stocks were 130 days of consumption in 1986 — today, it's only 53 days.
For analysts and campaigners stressing the climate factor as the keystone influence on food prices, it's also worth remembering that
grain stocks these days are also not particularly stressed, from the local (Kansas) level up through a global view.
World
grain stocks were drawn down a decade ago and we have not been able to rebuild them.
The research team also released six Eco-Economy Indicators on solar power, carbon emissions, wind power, ice melt,
grain stocks, and global temperature.
In decades past, when food prices spiked, the world could return idled U.S. cropland back into production or draw down
grain stocks.
For seven of the last eight years, the world has consumed more grain than it produced;
grain stocks are now at a historic low.
