Some Principles for Building Better and More Sustainable Cities

At the same time that we’re solving for climate change, we’re going to building cities for three billion people. That a doubling of the urban environment. So if we don’t control it properly, none of the climate control solutions do not help the humankind.  Hence, an appropriate urban planning paradigm is needed to control the climate change.

One of the wrong city development paradigms is the city sprawls. This paradigm has lots of downsides and drawbacks which should be cared. In the following, some of main disadvantages of sprawl paradigm will be discussed. The key attribute is that it isolated the people. It segregates people into economic enclaves, land-use enclaves and separate them from the nature. It does not allow the interaction that makes the cities great places and that make society thrive.

Secondly, it can cause more land consumption which environmentalists are really concerned about this. Destroying the nature and vegetation, can have adverse effects on the air pollution situation and biodiversity of the region.

Another negative point about the sprawl is the more distances that the people have to ride to get different places. This issue will lead to lots of knock-on effects. One of them is the increase of air pollution level that has a direct impact on global warming. Also, this more ride causes more expenditure for the citizens who have to traverse a long distance to get their destinations. Furthermore, when the people use cars or other vehicles, they have less this opportunity to walk which can improve the health condition and physical and even mental situation.

The mentioned issues are just some cases in point that demonstrate the negative aspects of city sprawl paradigm. Therefore it is necessary to plan and assign an appropriate solution as an alternative to this paradigm. For this purpose, there are 7 general principles proposed by experts in urban planning that can help to overcome the global sprawl as following.

  1. Preserve natural ecosystem, agrarian landscapes and cultural heritage sites
  2. Create mixed-use and mix income neighborhoods
  3. Design walkable streets and human scale neighborhoods
  4. Prioritize bicycle networks and auto free streets
  5. Increase the density of road networks and limit the block size
  6. Develop high quality public transportation
  7. Match density and mix to transit capacity

As a final point, it should be noted that majority of the urban problems are origin from our wrong habits and approaches to different issues and the cities condition are a demonstration of life style. Consequently, our life manner has a direct impact on our life environment in the cities.

Report (1): How to move toward healthier and more sustainable cities?

During last decades, cities has gained an increasing attention. The main reason of this issue is the alteration of specialists, policy makers and even folk viewpoint to the cities and urban life. Cities are comprised of more than just buildings and people and they have a significance impact on quality of human’s life. Hence, one of the assigned goals among sustainable development goals by United Nations is “Sustainable cities and Communities” (Goal #11) which is just a case in point to show the importance of cities.

Nowadays, urban planning and management is one the main challenges for governors and various strategies and plans has been utilized to make cities healthier and more sustainable. In the following, some of the most important ones has been investigated.

The most “liveable” cities – and some of the world’s most famous cities – are as known for their open space as they are for their culture. Hyde Park in London, Central Park in New York, the Bukit Timah Nature Preserve in Singapore, Phoenix Park in Dublin… all are attractions in their own right for inhabitants and visitors alike. Open space in urban environments provides many advantages: formal and informal sport and recreation, preservation of natural environments, provision of green space and even urban storm water management. Thus green space must be a key consideration in urban planning if the health of a city and its people are both considered important. A new, broader view of parks has also recently been emerging. This new view focuses on how policymakers, practitioners, and the public can begin to think about parks as valuable contributors to larger urban policy objectives, such as job opportunities, youth development, public health, and community building.

As the world’s cities continue to grow, continuing to value green space in cities is vital: but is also a challenge, particularly in developing nations where there is pressure for space, resources and development.

Another important strategy, is to reduce the using cars. Over the past four decades, cars have become far less polluting. Their fuel efficiency has practically doubled and their tailpipe emissions have been reduced by more than 95%. Yet lots of metropolitans are still battling smog and pollution. Therefore, it seems moving toward the strategy of less using cars by citizens is a more effective solution compared to cleaner cars. Nowadays, lots of plans has been presented by specialists which can materialize the goal of healthier and more sustainable cities more efficiency. In the next essays, some of the most significance ones will be investigated.
