Aproveitando a geografia do terreno, serão feitos diques à la Veneza. Assim também enchentes serão evitadas e serão minimizados os impactos ambientais às zonas de manguezais.
E terá várias novidades tecnológicas, como água semi-tratada canalizada para utilizar em descargas de privadas e irrigações.
Parece que a China está começando a olhar para esse aspecto. E já não era sem tempo:
Mao Tse-tung believed the natural world was all that stood between Communist China and its industrial future. His country, he said in a 1940 speech, "must use natural science to understand, conquer, and change nature." And conquer it did. Forests were razed, up to 90 percent of the trees in some provinces. The government, in a scheme to accelerate steel production, forced Beijing residents to smelt metal in hundreds of thousands of polluting backyard furnaces. New factories dumped untreated waste into the rivers until they turned a deep, noxious black. When China's economy began to take off in the 1980s, conditions got worse. Foreign firms put their most toxic manufacturing operations in China. Sudden prosperity, and a rush to boomtowns like Shanghai, drove energy demand well beyond what the grid could provide. Today, China opens an average of one new coal-fired power plant per week, the main reason it will pass the US in the next two years as the world's biggest source of CO2 emissions. Since 2001, China has increased its emissions more than every other industrialized country in the world combined.
This year, for the first time in history, the majority of the world's population lives in cities. By 2050, two-thirds will call a city home. Most of that urban growth will happen in the developing world. "Tokyo, London, and New York are extremely interesting," says Ricky Burdett, director of the Cities project at the London School of Economics. "But their massive development has already happened — in London, 150 years ago, in New York, 100 years ago, in Tokyo, 50 years ago." Shanghai represents the forward edge of the planet's next urban explosion.
These new megacities could evolve into sprawling, polluting megaslums. Or they could define a new species of world city. Unlike New York or London, they are blank slates — less affluent, perhaps, but also free from legacy designs and technologies tailored to the world of the 19th and 20th centuries. That is a huge advantage. It took Boston 20 years and more than $14 billion just to reroute a freeway underground. New York can hardly install a second network of water pipes. Most of Los Angeles is too spread out for fast public transit or combined heat and power plants. And because these cities are so isolated from agricultural land, most of the food that locals eat gets shipped hundreds of miles. "Shanghai today is making 90 percent of the mistakes that American cities made," Burdett argues — spreading out, building up single-family homes, replacing naturally mixed-use neighborhoods with isolated zones for living, shopping, and working, and connecting it all with car travel. But fixing these problems is still possible.
