General Description of the Research Project

Solving water issues in arid regions using advanced aquaponics
Demand for food in Mexico is increasing due to the rapid growth in population. However, problems exist, such as depletion of groundwater for irrigated agriculture and soil degradation due to the use of highly saline groundwater. In order to achieve both effective water use and prevention of soil salinization, this project is working on an advanced form of aquaponics, a food production system that combines aquaculture and hydroponic cultivation of crops. Further development of aquaponics technology can potentially make maximum use of water by linking the system to open-field cultivation. Specifically, fish and shrimp are farmed using groundwater, and the drainage from that process is used for hydroponic cultivation of crops that have the property of absorbing salts. The water with reduced saline content resulting from hydroponic crop production can then be used for open-field cultivation.

Converting irrigated agriculture into highly productive systems around the world
If aquaponics suited to arid regions were adopted throughout the world, irrigated agriculture could be converted into a sustainable food production system. The deployment of these highly productive systems will contribute to securing safe water and food, countering threats to food security.
