Urbanisation

Urbanisation is a population shift from rural to urban areas, "the gradual increase in the proportion of people living in urban areas” and the ways in which each society adapts to the change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Urbanisation is relevant to a range of disciplines, including geography, sociology, economics, urban planning, and public health.

This unprecedented movement of people is forecast to continue and intensify during the next few decades, mushrooming cities to sizes unthinkable only a century ago.

According to The United Nations’ projections, half of the world's population will live in urban areas at the end of 2008. It is also predicted that, by 2050, about 64% of the developing world and 86% of the developed world will be urbanised. That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia.

Degree of Urbanisation
Today, in Asia, the urban agglomerations of Osaka, Karachi, Jakarta, Mumbai, Shanghai, Manila, Seoul, and Beijing are each already home to over 20 million people, while Delhi and Tokyo are forecast to approach or exceed 40 million people each within the coming decade.
Urbanisation creates enormous social, economic and environmental changes, which provide an opportunity for sustainability with the “potential to use resources more efficiently, to create more sustainable land use and to protect the biodiversity of natural ecosystems.”

PVC will contribute in many ways to efficient use of resources: Sophisticated window frames with very low heat transmission and no maintenance requirements, highly durable, encrustation resistant piping systems to supply drinking water and evacuation of waste water, electrical cables and conduits, easily cleaned flooring and wall covering, and light reflecting roofing. Urbanisation is not merely a modern phenomenon, but a rapid and historic transformation of human social roots on a global scale, whereby predominantly rural culture is being rapidly replaced by predominantly urban culture.

As the population continues to grow and urbanise at unprecedented rates, new urbanism and smart growth techniques will create a successful transition into developing environmentally, economically, and socially sustainable cities. This requires among others efficient management of end-of-life construction products. PVC can easily be separated from other plastic construction products and can be recycled several times without loss of properties

Smart Growth and New Urbanism’s principles include walkability, mixed-use development, comfortable high-density design, land conservation, social equity, and economic diversity. Mixed-use communities work to fight gentrification with affordable housing to promote social equity, decrease automobile dependency to lower use of fossil fuels, and promote localised economies.
