Considerations and cases in regards to the water cicle

Abstract

Environmental sustainability is directly related with the water cicle and the interventions of men on it, as much in its extraction, use and elimination. The conservation of soil and vegetation invariably depend on the acumulated impact of this process. The perspective of a major climatic change, with the subsequent increasement of the planet‚s temperature, implies radical transformations in the water cicle, and thus, in its disposability and utilization. That is why it is overbearing to improve radically the saving of water, increasing at the same time the depuration systems and efficiency on the irrigated land. The author makes a series of propositions in this direction.
