 Water footprint in supply chain indicator of water use so it shows for a certain product How much water is being used in all steps along the supply chain and that's interesting because in many places in the world there is water intensive processes also water pollution In many places this leads to over-exploitation and water pollution problems, so it's interesting for a product to know where it comes from and whether the product somehow relates to water pollution or water over-exploitation in its supply chain If we look at the water footprint of whole nations, we look at what is being consumed within the country and then we see differences all over the world. We see developing countries like China and India with a relatively low water footprint per capita on the other hand we have countries like the USA and also Southern European countries that have a huge water footprint per capita sometimes more than twice the global average, then we have countries like the UK, Ireland Germany, and the Netherlands that have a water footprint around the global average For governments it would be most appropriate if they said water footprint caps per river basin It means that there is a maximum amount of water available per river basin and maximum add of the rain in a basin So a water footprint cap will make sure that the water footprint within the basin will not exceed the maximum sustainable water footprint So this is what governments should do in every catchment in the world and also what they should do is promote water use efficiency for instance by formulating water footprint on benchmarks by product so that there is incentive for companies to reduce the water footprint of their products down to the benchmark and Finally, of course, we should address the issue of equity. Some countries in the world the consumers have a much bigger water footprint per capita than in other countries So we may need something like Kyoto Protocol for water that arranges and make sure that our water footprint reduction targets their country
