ABSTRACT
ABSTRACT: The hydrological region Rio Bravo/Grande is the largest in Mexico, and mainly arid and semiarid, its basin is shared with USA. The growing water demand of various uses has caused severe shortages, which has been solved through aquifers’ over exploitation and over allocation of surface water. In addition, the region is subject to severe and recurrent extreme weather phenomena, including droughts and flooding. The region submits an important annual water volume to the USA, because of the International Water Treaty, signed in 1944. There is strong evidence that present water gap is large and will be greater, if specific measures are not implemented to control and revert this situation. The risk of system collapse is high with potentially severe consequences. This paper addresses this condition, and some possible solutions are proposed in a planning horizon by 2030 in order to achieve water sustainability and equilibrium, considering the objectives of the 2030 Water Agenda for Mexico.
