In many cities, planners tend to arrange shops, schools, offices, and homes in specific areas and separate them from each other. Do you think the advantages of this policy outweigh the disadvantages?
In modern urban planning, it is a common practice to zone cities into separate functional areas for residential, commercial, educational and office use. In my opinion, the drawbacks of this approach far exceed its limited benefits.
Admittedly, segregated land use can reduce conflicts between different urban functions to some extent. For instance, if heavy-traffic shopping malls and office towers are separated from quiet residential neighbourhoods, residents are less likely to be disturbed by constant noise and air pollution from vehicles and crowds.
However, this policy creates far more serious problems. The most evident one is longer commuting distance. When homes are isolated from offices and schools, most working people and students have to travel long distances between different zones every day. This not only causes heavy rush-hour traffic congestion, raising carbon emissions, but also takes up time people could otherwise spend resting or with family. For example, in many newly developed zoned districts in Chinese cities, some residents spend over 2 hours daily commuting between suburban homes and downtown workplaces, greatly reducing their life quality.
Additionally, separating functions can kill urban vitality. When residential zones have no nearby shops, offices or public facilities, they become empty "ghost towns" during working hours, while commercial and office zones turn desolate at night, which also raises safety risks and wastes public infrastructure. By contrast, mixed-use neighbourhoods where people can live, work and shop within walking distance are far more convenient and lively.
In conclusion, although functional zoning has minor merits in reducing mutual interference, it leads to longer commutes and lost urban vitality, so its disadvantages outweigh its advantages.
