Klaus Schwab, executive chairman of the World Economic Forum, and Brabeck-Letmathe who is chairman and chief executive of Nestle, are corporate heavy-hitters. They aren't tree-huggers or leftist moonbats or doom-mongers by any stretch of the imagination. So when they say the world should be very, very worried about scare water, maybe we should listen. On Monday, they had an op-ed in The Australian, which is owned by that other non-moonbat Rupert Murdoch's News Corporation.
THE world is on the verge of a water crisis. As the global economy and the world's population continue to expand, we are becoming a much thirstier planet. It is important to realise just how much water we need to make the various aspects of our economy work.Water scarcity is already limiting growth in many US cities. More importantly, it is the underlying prime cause behind several brushfire wars and civil conflicts in sub-Saharan Africa, including the Sudan. When the authors write about "water stress" what they mean is famine, war, mass migration, increased political instability, terrorism and intolerable stresses on the world's economy. This isn't on anyone's radar as a policymaking urgency in the current US election race. But it should be.
Every litre of petrol requires up to 2.5litres of water to produce it. On average, crops grown for their bio-energy need at least 1000 litres of water to make one litre of biofuel. It takes about 2700 litres of water to make one cotton T-shirt, up to 4000litres of water to produce 1kg of wheat and up to 16,000 litres to produce 1kg of beef.
...Along the Colorado, the Indus, the Murray Darling, the Mekong, the Nile or within the North China Plain, for example, do we use the scarce water for food, for fuel, for people and cities, or for industrial growth? How much of the upstream river can we really dam? How do we figure out ways for every actor in the economy to get the water they need to meet their human, economic and cultural aspirations? And can we ensure that the environment is not wrecked but can flourish in the process?
These are tough questions. And unlike carbon reduction, there is no alternative, no substitute to promote. Nor is there a global solution to negotiate. Turning off your tap in Vancouver or Berlin will not ease the drought in Rajasthan or Australia.
Water is local. Water basins will become the flashpoints. These are the large areas that drain into the world's major rivers and eventually into the sea. They contain millions of people, farmland, forests, cities, industry and coastline, and often straddle multiple political boundaries. The sector that will get the most attention will be the water used by agriculture for food and textile production: 70 per cent of all our freshwater withdrawals are in this sector. Savings made here can help elsewhere in the water basin.
The International Water Management Institute had 500 scientists examine the water we use for agriculture.
Their report took five years to complete. It found that we will not have enough water to supply global demand for food during the next few decades unless urgent and substantial reforms in water and agriculture are undertaken.
Climate change will create this situation more quickly and make it worse. The latest Intergovernmental Panel on Climate Change report says that if global average temperature rises by 3C, hundreds of millions of people will be exposed to increased water stress. It provides the wake-up call we all need to start acting on water.
We can see this crisis unfolding during the next few years. A perfect storm is approaching. And all this sits on top of today's morally indefensible situation where 20 per cent of the world's population is without access to improved water supply.
But it is not a catastrophe yet. It lies within our collective grasp to find the solutions. Business can improve its water efficiency, and in many cases it has raised the bar. There are many success stories. But it will take everyone in the water basin working together to change the overall game.
