The Pajaro Valley, in the Monterey Bay area of California, is ideally suited for agriculture. In fact, the Pajaro Valley and the nearby Salinas Valley produce nearly half of the strawberries grown in the United States yearly. But, the water source for the valley is a confined underground aquifer that is slowly being depleted. In January of 2011, the American Institute of Mathematics held a Sustainability Problems workshop with the goal of bringing together mathematicians and industry representatives to work on a variety of sustainability problems, including renewable energy, air quality, water management, and other environmental issues.
