When it comes to environment, the efforts for a greener future should begin at home. But, do we have enabling infrastructure for this purpose? The answer would be no in most of the cases. However, a new city design, if adopted, could make the present compact lives greener than ever. Named as Valley Effect, the new design promises to develop a carbon positive ecosystem of built and natural environments. It tries to achieve the environment-friendliness of natural valleys in a compact urban setting with the help of interconnected towers featuring a unique model of terraced urban farming.
