Davos Must Deal with the Water Crisis

We are on the verge of a water crisis. As we continue to grow our world economy and population, we are becoming a much thirstier world. It is important to realise just how much water we need to make every aspect of our economy work. And we need to adapt our water use to a fast-changing world while we still can. Every litre of petrol requires up to 2.5 litres of water to produce it. On average, crops grown for their bio-energy need at least 1,000 litres of water to make one litre of bio-fuel. Davos 2008 in full Biofuels and water shortages Water is the new oil GM plants that save water It takes about 2,700 litres of water to make one cotton T-shirt, up to 4,000 litres of water to produce a kilo of wheat and up to 16,000 litres to produce a kilo of beef.The statistics are equally surprising for hundreds of other consumer products that we all take for granted such as milk, juice, coffee, fruit, pizza, detergents, carpets, paint, electrical appliances and cosmetics. On average, wealthier people "consume" upwards of 3,000 litres of water every day. Even to produce the much more basic things our economy needs, such as cement, steel and chemicals, takes tonnes of water as do mining and power generation.We have seen this year the impact on food prices that a combination of crop switch for bio-fuels and drought can have. Water is the bigger problem we can see behind this issue. It has the potential for a much more profound impact on consumers and voters. In the breadbasket areas of the world, which help feed our fast-growing urban populations, we are heading for painful trade-offs or even conflict.Along the Colorado, the Indus, the Murray Darling, the Mekong, the Nile or within the North China Plains 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 participant in the economy to get the water they need to meet their human, economic and cultural aspirations? And how to ensure the environment is not wrecked but can flourish in the process?These are really 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 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 - 70pc 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. They found that we will not have enough water to supply global demand for food over the next few decades unless urgent and substantial reforms in water and agriculture are undertaken.Climate change will make this situation happen more quickly and to a worse degree. The latest Intergovernmental Panel on Climate Change report says if 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 over the next few years. A perfect storm is approaching. And all this sits on top of the morally indefensible situation of today where 20pc of the world's population are without access to clean water.But it is not a catastrophe yet. It lies within our collective grasp to find the solutions. Business can improve its water use 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. This is what makes the challenge complicated. We are ahead of the curve for now. Addressed smartly, innovatively and with new forms of collaboration between government, business and industry we believe the coming crisis can be averted.It is against this backdrop that we will come together at the World Economic Forum later this month in Davos, Switzerland, to raise the economic and political profile of water - to raise awareness among our business colleagues, our politicians and society at large about how we will need to adapt to this fast arriving challenge.How can we start moving now to ensure we organise a water secure world for everyone, including our own businesses, by 2020? Our aim is to catalyse at this year's Davos meeting an unprecedented, high impact public-private coalition to help find ways for us all to manage our future water needs before the crisis hits. Klaus Schwab, founder and executive chairman of the World Economic Forum, and Peter Brabeck-Letmathe, chairman and chief executive officer of Nestlé
