Just finished reading Make Room Make Room, the Harry Harrison book upon which the film Soylent Green was based. I can heartily recommend it as a challenging piece of apocalyptic dystopia, describing a world starved and parched by rampant overpopulation and mismanagement of resources. It came complete with an afterword by Harrison in which he said he 'hopes he's proved wrong'
Well, according to "the UK government's chief scientific adviser" John Beddington, the world is doing all it can to make sure he's not ...
The BBC is reporting Beddington's warning of a possible 'perfect storm' crisis in 2030.
As the world's population grows, competition for food, water and energy will increase. Food prices will rise, more people will go hungry, and migrants will flee the worst-affected regions.
Specifically, he points to research indicating that by 2030 "a whole series of events come together":
The world's population will rise from 6bn to 8bn (33%)
Demand for food will increase by 50%
Demand for water will increase by 30%
Demand for energy will increase by 50%

Water, water everywhere ...
... and, increasingly, not a drop to drink.
Having just spent a couple of weeks in Kenya and seeing the ecological, political AND humanitarian effects of lack of water, this piece by Brian Richter, director of the non-governmental Global Freshwater Program at The Nature Conservancy, is very alarming.
The front pages of Kenya's newspapers are still dominated by the Mau controversy over the near-total destruction of one of the country's key forest 'water towers' that has left the nation's capital. Nairobi, facing severe water shortages and power black-outs, with a dry summer undoubtedly about to lead to crippling food shortages. And that's just one country, a single country that technically shouldn't be facing a water crisis - if only politicians hadn't handed out publicly-owned forest to ordinary people, which they understandably then converted into farm land.
And the world is only going to get thirstier ...
Let us start with our global population, expected to rise from nearly seven billion to nine billion in just a few decades. That is why more than half the world's population will be living in areas of high water stress by 2030.
At the same time, in populous nations such as China and India, improvements in living standards and personal incomes are linked to greater consumption of clothing, meat, and water.
It takes 140 litres of water to produce one cup of coffee; 3,000 litres to make a hamburger; and 8,000 litres to create a pair of leather shoes. All of these processes require a vast amount of water to grow crops, feed cows, or produce leather.
On top of that, climate change will bring less rain to many regions, and cause it to evaporate more quickly almost everywhere.
Accordingly, the International Panel on Climate Change (IPCC) has concluded that "the proportion of the planet in extreme drought at any time will likely increase".
