It's more than a timely warning - especially for those in the world who are satisfactorily housed and have an abundance of food and water available to them.
The Guardian reports in "Asia facing unprecedented food shortage, UN report says":
"Asia faces an unprecedented food crisis and huge social unrest unless hundreds of billions of dollars are invested in better irrigation systems to grow crops for its burgeoning population, according to a UN report published today.
India, China, Pakistan and other large countries avoided famines in the 1970s and 1980s only because they built giant state-sponsored irrigation systems and introduced better seeds and fertilisers. But the extra 1.5 billion people expected to live on the continent by 2050 will double Asia's demand for food, says the report from the UN's Food and Agriculture Organisation (FAO) and the World Bank-funded International Water Management Institute (IWMI).
A combination of very little new land left for cultivation, an increasingly unpredictable climate and water supplies stretched to the limit means the only realistic option to feed people in the future will be better management of existing water supplies, according to the report.
"There is no new land or water to develop so we have to make more use of what we have. Existing irrigation systems are often 50 to 70 years old. They are leaking and water is evaporating. We urgently need a new generation of irrigation. That is the only way we are going to feed everyone," said Colin Chartres, who is the director general of IWMI."
