Recently, a gradual decrease in the fertility rate has slowed in a number of countries ( 2, 3 ), most notably in China and India ( 4 ), which has led to upward revisions in population forecasts. Many people in these nations are poor and malnourished now, and are unlikely to be able to afford the import of foods that would be necessary to make up for their water deficiencies. That declining point varies in different reports and it can be less or more depending on the rate of development of water deficits, in turn determined by the root-zone water storage capacity and the evaporative demand.

Investigating the effects of infection, water quality, or stress on overall production quality of the animal means working with herds or other large groups to track and manage how those animals are affected by the events of their everyday lives. In a traditional model where computer power and data storage needs must follow a “worst-case” model (that is, cover off the very highest levels of expected utilization), compute and storage capabilities often lie dormant in periods of less actvity, thereby negatively affecting your overall return on investment.
