摘要

Urbanisation is prevalent. The United Nations has reported that today, more than half of the world's population lives in cities. By 2050, this proportion is expected to increase to 70 percent (Figure 1). As urbanization continually increases, so do associated problems accumulate. One of the most pertinent issues would be this - how will the world feed this ever-burgeoning urban population as agricultural land correspondingly declines to make way for the expanding urban areas? Some cities attempt to solve the problem of increasing food demand and decreasing food supply by importing, not realising that this in fact leads to other sustainability problems such as global warming.
