Beefed-Up Diets of Asia's Middle Class Could Lead to Chronic Food Shortages

Scientists have said that the beefed-up diets of Asia's expanding middle class could lead to chronic food shortages for the water-stressed region.

According to a report in National Geographic News, the threat was highlighted in a study by the International Water Management Institute (IWMI) and the UN Food and Agriculture Organization (FAO), which estimate that Asian demand for food and livestock fodder will double in 40 years.

Asia Faces Food Shortage by 2050 Without Major Water Reforms, Study Warns
A new study by scientists has warned that without major water reforms, the prospect of a food shortage by the year 2050 looms large in Asia.

Asia's growing economy and appetite for meat will require a radical overhaul of farmland irrigation to feed a population expected to swell to 1.4 billion by 2050, scientists warned at Stockholm's World Water Week recently.

At current crop yields, East Asia would need 47 percent more irrigated farmland and to find 70 percent more water, the study found.

South Asia would have to expand its irrigated crop areas by 30 percent and increase water use by 57 percent.

World Blames China's Industrialization For Worsening Global Food Shortage
A new research by the University of Leeds, UK, has determined that industrialization of China is increasing the fragility of global food supply, with reports indicating that global

Given existing agriculture pressure on water resources and territory, that's an impossible scenario, according to the study authors.

Scientists urge modernization of existing large-scale irrigation systems, most of which were installed in the 1970s and 1980s.

Scientists Predicting Severe Water Shortage In the Coming Decade
Scientists and engineers have said that they will have to face a host of obstacles over the next decade in providing clean water to millions of people caught up in a water shortage crisis.

It's estimated that India, the world's largest consumer of underground water, has 19 million unregulated groundwater pumps.

Groundwater in northern India is receding by as much as a foot (0.3 meter) a year due to rampant water extraction, most of it for crop irrigation, according to a study.

China Faces Acute Water Shortage, Turns To The Sea To Solve The Problem
China is turning to the sea to solve the growing problem of water shortages afflicting the country and cut utility costs as well, indicates recent reports.

More than 109 cubic kilometres of groundwater were drained from the region between 2002 and 2008, according to the satellite image-based study led by scientists with NASA's Goddard Space Flight Center.

"Governments' inability to regulate this practice is giving rise to scary scenarios of groundwater over-exploitation, which could lead to regional food crises and widespread social unrest," said Tushaar Shah of IWMI.

As for China, the country's per capita "water footprint" for food production has almost doubled since 1985, according to Junguo Liu of the Beijing Forestry University.

"A switch from traditional rice and noodles to a meatier diet is behind the change," Liu said. "Changes in food consumption are the major cause of worsening water scarcity in China," he added.

Total water requirements for food production in China are predicted to rise by 40 to 50 percent in the next 30 years, he further added.

"Where do you get such a big amount of water? It is a really big question and a big challenge," he said.

"If other developing countries follow China toward a Western diet, the global water shortage becomes even more serious," he added.
