Did you know? China is planting a belt of trees to protect land from the expanding Gobi Desert. This Great Green Wall is projected to extend some 4,480 kilometers (2,800 miles), stretching from outer Beijing through Inner Mongolia (Nei Monggol). Unfortunately, recent pressures to expand food production appear to have slowed this tree planting initiative. For more information view the text and data in Chapter 8 of Plan B 4.0: Mobilizing to Save Civilization.
The Arab countries in the Middle East and North Africa make up only 5 percent of the world’s population, yet they take in more than 20 percent of the world’s grain exports. Imports to the region have jumped from 30 million tons of grain in 1990 to nearly 70 million tons in 2011. Now imported grain accounts for nearly 60 percent of regional grain consumption. With water scarce, arable land limited, and production stagnating, grain imports are likely to continue rising.
Egypt is the largest grain producer in the Arab world, accounting for almost 40 percent of the region’s harvest. Its grain production has doubled over the last 20 years. But because nearly all of the country’s available freshwater and arable land is already used for agriculture, further expansion of the grain harvest is unlikely.
In the 1980s, Saudi Arabia began pumping fossil water from deep underground, allowing it to farm the desert. By subsidizing wheat production at several times the world price, Saudi Arabia became the second largest Arab wheat producer in the early 1990s. At its peak, Saudi Arabia harvested more than twice the wheat it consumed, exporting the excess. But with the underground water supplies nearly depleted, wheat production has plummeted. By 2016, Saudi Arabia plans to phase out wheat production entirely. In a span of 25 years, the country will have gone from exporting wheat to relying exclusively on imports.
Across the Arab world, grain production is stagnating, yet grain demand is growing rapidly as population expands. Since 1960, the region’s population has nearly quadrupled to 360 million. By 2050 the region is projected to add another 260 million people, dramatically increasing pressure on already stressed land and water resources.
But population growth is not the only factor increasing demand for grain. With policies in many Arab countries encouraging meat production, the amount of grain used for livestock and poultry feed has soared from less than half a million tons in 1970 to 40 million tons in 2011. Increased meat and dairy consumption have raised grain use per person by 50 percent over that period.
Thus far, grain imports have filled the widening gap between production and consumption. But population growth alone will raise grain demand in the Arab Middle East and North Africa to 200 million tons by 2050, equal to two thirds of current world grain exports. Increased meat consumption would take demand up even higher. Ensuring grain supplies will become progressively more challenging as countries look to import more grain from abroad.
