Aug 2 2011: The first step is to ensure the sufficiency of urban energy supply; moreover, this means that there is a need of investment in smart, and secure, electric grids, which are going to support a transition from vertically distributed fossil fuel, to systems of renewable energy.
Then, the second step is investment on urban argriculture, which is a method who is currently being tested, in countries such as Singapore, and which can minimize the cost of food by eliminating the need for distant transportation; in adiition to that, genetically engineered food, and specifically meat, can make the production of protein based food, conceivable, in an urban environment.
Finally, water sufficiency can come from two places, and non of them are rain water, because it is clealy insufficient to support the populations of modern megacities. Therefore, cities are going to have to use recycling technologies, to clean, and recycle, the water which has being consumed, and then they need to invest on desalination plans, which are going to allow us to access, the virtually abudant reserves of the oceans of the planet.
Therefore, in conclusion, the conjunction between smart grids and renewable energy, urban argiculture, disalination, and recylcing, are going to create the cities of the future.
