Estimating Water Consumption in Irrigation District in Mexicali Valley, Mexico. Irrigated farming uses up to 85 % of the managed water in the world to produce food, forages, and fibers for 7.5 billion people. Irrigation is a strategic activity for food security and development. New discoveries and inventions made farming more productive. During the Twenty Century, enormous semiarid regions were open to productive farming supported by irrigation. The Green Revolution developed high yield crops. This helps to avoid terrible famines of the past. Irrigation water is in high demand, thus reservoirs and aquifers show abatement. We have been using water at an unsustainable rate and got used to a limited and no easily renewable resource: Water. We have been covering the water deficit of many farming regions and cities with groundwater. The general level of abatement is worrisome; we need to do a global balance of the aquifers. Many of them are overused, and some already have collapsed, like the Aral Sea. This balance require the use of remote sensing and GIS to estimate total water consumption. This study analyses the Mexican side of the Delta of the Colorado River, the Mexicali Valley in Mexico, and estimates the total usage of irrigation water. This paper summarizes a struggle that reached critical conditions due to the extended drought in Southern California. The development of the border region between California and Baja Mexico. Under the unfavorable, water wise, climate change prediction for the Colorado River Watershed.
