There is no turning back and the number of people that share the world’s limited resources continues to rise.

He explains, “We can’t go on when 20 percent of population uses up 80 percent of the resources. As planners we have to remember that consumption is a consequence of demand, and demand is a consequence of design.” He continues, “Much of green urbanism is common sense urbanism. It is easy to reduce the demand with good design and green urbanism has to become the norm for all urban developments.”
Lehmann’s model for green urbanism is based on three pillars: energy and materials; water and biodiversity; urban planning and transport. The premise is that an efficient interaction between the three will translate to a successful model. “Green urbanism is interdisciplinary,” Dr. Lehmann believes. “It requires the collaboration of landscape architects, engineers, urban planners, ecologists, transport planners, physicists, psychologists, economists and other specialists, in addition to architects and urban planners. Green urbanism makes every effort to minimize the use of energy, water and materials at each stage of the city’s life cycle.
