Imports of grain globally increased more than fivefold between 1960 and 2013 as more nations turned to international markets to help meet domestic food demand.1 (See Figure 1.) For some countries, the imported share of domestic grain consumption has risen substantially.2 In 2013, more than a third of the world’s nations—77 in all—imported at least 25 percent of the major grains they needed.3 This compares to just 49 countries in 1961, an increase of 57 percent over half a century.4  (See Table 1.) ...

Peak oil has generated headlines in recent years, but the real threat to our future is peak water. There are substitutes for oil, but not for water. We can produce food without oil, but not without water.

We drink on average four litres of water per day, in one form or another, but the food we eat each day requires 2,000 litres of water to produce, or 500 times as much. Getting enough water to drink is relatively easy, but finding enough to produce the ever-growing quantities of grain the world consumes is another matter. ...

UN special rapporteur on the right to food champions agroecology as sustainable alternative to existing framework

The existing food system has failed and needs urgent reform, according to a UN expert who argues there should be a greater emphasis on local food production and an overhaul of trade policies that have led to overproduction in rich countries while obliging poor countries – which are often dependent on agriculture – to import food. ...

SINGAPORE, Jan 30 (Reuters) - Extreme heat can cause wheat crops to age faster and reduce yields, a U.S.-led study shows, underscoring the challenge of feeding a rapidly growing population as the world warms.

Scientists and farmers have long known that high heat can hurt some crops and the Stanford University-led study, released on Monday, revealed how the damage is done by tracking rates of wheat ageing, or senescence. ... Read more about Extreme heat hurts wheat yields as world warms-study

Marked each year on March 22, the United Nations hopes the 2012 event will focus attention on water's critical role in feeding the world.
