Water resources management determines a large of a country's economic activities. There is a need to meet growing water demand (not just domestic and public but also for agriculture, cattle raising, industry, the leisure sector and tourism, and energy production) and to prevent greater degradation of ecosystems and natural processes, by ensuring the availability of sufficient quality resources in the future. That is why it is said that there are 1.4 billion jobs, 42% of the world’s employed workforce, that depend to a large extent on water, and that essentially practically 80% of jobs require access to water resources whether directly or indirectly. Therefore, the professional possibilities that the Master in Water Resources Science and Technology brings are enormous in number and range, not just in the water sector but in any other industrial sector too.
