With over three quarters of water covering the planet and 70% of human body consisting of water, this wonder liquid permeates both land and body, making it an essential substance both for the development and nourishment of life and the sustenance of the environment. For human needs—apart from our dependence on it for survival—water also lies at the heart of economic and social development. In times of abundance, water enables economic growth, which in turn reduces poverty, and in times of scarcity, it can cause life-threatening crises. To be able to predict such disasters, water monitoring is of utmost importance.
