Water is the basis of all life on Earth. Without water, agriculture, and hence food production, would not be possible, and this sector accounts for more than two thirds of global freshwater consumption. However, freshwater is a scarce resource. And it is becoming ever scarcer, also because of global warming effects. Here, clever solutions are needed, solutions ensuring that the scarce resource of water is used optimally while taking the needs of all stakeholders into consideration – in line with the “Leave no one behind” principle of the Sustainable Development Goals.
