Answer:
The water footprint shows the extent of water use in relation to consumption by people. The water footprint of an individual, community or business is defined as the total volume of fresh water used to produce the goods and services consumed by the individual or community or produced by the business.
The four major direct factors determining the water footprint of a country are: volume of consumption (related to the gross national income); consumption pattern (e.g. high versus low meat consumption); climate (growth conditions); and agricultural practice (water use efficiency).

Answer:
Everything we use, wear, buy, sell and eat takes water to make.
The water footprint measures the amount of water used to produce each of the goods and services we use. It can be measured for a single process, such as growing rice, for a product, such as a pair of jeans, for the fuel we put in our car, or for an entire multi-national company. The water footprint can also tell us how much water is being consumed by a particular country – or globally – in a specific river basin or from an aquifer.
The water footprint is a measure of humanity’s appropriation of fresh water in volumes of water consumed and/or polluted.
The water footprint allows us to answer a broad range of questions for companies, governments and individuals. For example:
where is the water dependence in my company’s operations or supply chain?
how well are regulations protecting our water resources?
how secure are our food or energy supplies?
can I do something to reduce my own water footprint and help us manage water for both people and nature?
Depending on the question you are asking, the water footprint can be measured in cubic metres per tonne of production, per hectare of cropland, per unit of currency and in other functional units. The water footprint helps us understand for what purposes our limited freshwater resources are being consumed and polluted. The impact it has depends on where the water is taken from and when. If it comes from a place where water is already scarce, the consequences can be significant and require action.
