Population Growth: The Problems Created By Urbanization

As the world continues to grow, population growth is clearly one of the big problems mankind faces. The world of the 21st century shows how science, medicine, and technology can support human life while creating a vision of human prosperity. Many of these advances are positive, but bring many challenges that society must face. The emergence of large cities such as Mumbai in India is likely to lead to many problems such as urbanization seeking better opportunities such as poverty, poor living and health, and extreme depletion of environmental resources It is an important example.

Urban growth is defined as the rate at which urban population increases. This is the result of urbanization, the flow of people from rural to urban areas. Growth of the city may lead to economic development of the country. Urban growth is also known as the expansion of metropolitan areas or suburbs to the surrounding environment. Because the impact of urban growth directly affects the economic development of the country, it can be regarded as an indicator of the economic situation of the country. There are more metropolitan areas, more work, it will also bring economic growth.

As population continues to increase and urbanize at unprecedented speeds, new urbanization and smart growth techniques have been implemented to create a transition to a development environment, economically and socially sustainable cities. Intelligent growth and new urbanism principles include walking, combined use development, comfortable high density design, land protection, social equity, and economic diversity. The multipurpose community aims for high end through affordable housing for promoting social equity, reducing dependence on automobiles for fossil fuel use, and promoting regional economies. The per capita GDP of the easy-to-walk community is 38% higher than the low-mobility city subway (Leinberger, Lynch). By combining economic, environmental, and social sustainability, cities are more equitable and resilient than the expansion of cities that use the land too much, promote the use of cars, and economically isolate the population There will be, it will be attractive.

Looking at the UN population forecasts from urban and rural areas, it is expected that a significant portion of the world's population growth between 2000 and 2030 will concentrate in urban areas. It is estimated that the urban population in 2000 is about 2.9 billion people and it is estimated to reach about 4.9 billion people by 2030 (Figure 10.2). Much of the future growth will come from cities in developing countries. The urban population of developing countries is projected to increase from 1.9 billion in 2000 to about 3.9 billion in 2030, accounting for almost all of the increase in population growth in developing countries. However, only a fraction of it is due to an increase in migration from rural areas to cities. It is also important to convert rural settlements into urban areas, the most important of which is the increase in the natural city population.
