Transcript of Population/Urbanization Effects
Chain Reaction to Negative and Positive Effects
-Large Manufacturing Centers
-Availability of easy transportation
Effects Public Health
-Sanitation- Over population leads to unsanitary living conditions
-Pollution- Caused by smoke, and smog
-Fire Hazards- Due to such close proximity
-Epidemics- Due to spread of diseases caused by contaminated water and air
-Reduced transportation costs
-Exchange of ideas
-Social and Religious Taboos disappearing
-Diffusion of Urban culture or rural areas
the act or fact of urbanizing, or taking on the characteristics of a city:
Urbanization has led to more air pollution and increasing childhood asthma.
Urbanization is the shift from a rural to an urban society, bringing a large concentration of people into towns and cities. This process usually occurs when a nation is still developing. The trend toward urbanization is a worldwide phenomena. The chief cause of global urbanization is the new economic opportunities it brings to people and governments; however, it has both positive and negative effects on society
-Shortage of housing
-Lack of public transportation
-Public health issues
-Easy spread of disease due to over population
-Loss of privacy
-Shortage of livable housing
Social Effects: Poverty
-Poverty is caused by lack of opportunities
-Poverty causes malnutrition and illnesses; major factor of mental stress
As the world continues to urbanize, sustainable development challenges will be increasingly concentrated in cities, particularly in the lower-middle- income countries where the pace of urbanization is fastest. Integrated policies to improve the lives of both urban and rural dwellers are needed.
Continuing to Urbanize
The human population has lived a rural lifestyle through most of history. The world’s population, however, is quickly becoming urbanized as people migrate to the cities. This figure shows the urban population growth between 1950 and the year 2000. In 1950, less than 30% of the world’s population lived in cities. This number grew to 47% in the year 2000 (2.8 billion people), and it is expected to grow to 60% by the year 2025
The rapid growth of urban areas is the result of two factors: natural increase in population (excess of births over deaths), and migration to urban areas. Natural population growth has been covered in other units, and consequently, here we will concentrate on migration.
Enacting growth boundaries, parks and open space protection
•Planning for and directing transportation dollars to promote public transportation.
•Reversing government programs and tax policies that help create sprawl.
•Revitalizing already developed areas through measures such as attracting new businesses, reducing crime and improving schools;
•Preventing new development in floodplains, coastal areas and other disaster prone areas
