In freshwater and lowsalinities water, the tendency should be to reduce the consumption of freshwater. However, in this study, a minimal amount of water was used in comparison with the monoculture shrimp systems. The shrimp farms of northwest Mexico that most commonly utilize semi-intensive systems have estimated a water consumption rate of 67 and 113 m 3 per kg of shrimp. In our work, we calculated a total usage of 4.7 m 3 of water per kg of shrimp harvested, while the water usage rate for which both shrimp and tomato were considered was 2.1 m 3 kg. It is important to indicate that this value could be further reduced by optimizing the ratio of the shrimp area to the tomato area and by utilizing the water that remains after the shrimp are harvested.In the same manner as agriculture, irrigation is at a crossroads. The types of irrigation investments that are made and the way they are made are changing substantially . Innovation with improvements is therefore needed in the investments in and management of irrigation. Under this context, the utilization of water by two or more cultures constitutes a significant alternative,
