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.
