Then reply to and peer-review at least three other posts by next Wednesday 11:59PM UoPeople Time, and rate the posts and replies.

There are many current projects around the world to support sustainable development and growth in urban areas.
The general goal is to create livable cities in which people have open spaces, nature, and areas for congregation and relaxation.

The idea is also to have well developed public transport systems that would reduce the need for cars and other transport that contribute to air pollution.

Through good education programs, there can be less litter and reduced waste. Finally, the thoughtful use of more eco-friendly products, renewable energy, and materials can make a huge difference in reducing both waste production and energy use.

Basically, cities can be built and developed in a way that is healthy for the local environment as well as those living within the city.

Curitiba, Brazil, is a city that has become a model of sustainable city growth and quality urban planning.

At the following links, you can learn more about the different ways in which Curitiba, and its mayor, have supported sustainable, environmentally friendly, urban growth.

Read and learn about this city at the following links and the textbook, then answer the questions below:

Questions to answer:

  1. What is the most significant change or project in the city of Curitiba that you feel has influenced it becoming more livable, clean, or sustainable?
  2. What do you think the future steps in Curitiba should be? For example, what would be a good ‘next project’ to continue their movement forth in sustainable development and quality urban planning?
  3. Do you feel that any of the planning, projects, policy, education programs, and/or changes they have made would work well in your own city? Which one, and why? Explain.

Hello, please find my answers below for this week’s discussion assignment.

1. I think the most influencing change is Curitiba’s public transport system. It has reduced the heavy traffic resulting in personal transport with cars.

 Reducing private transport in the city has a positive impact on the pollution of the air. It also is a sustainable solution that increases the livability of the city  (Gnatek, 2013).

2. The county of Paraná has a lot of universities. Why not make one big school to lower the administration costs and gain higher efficiency in the structures?

Another idea is maybe the automation of some government processes – many countries already try to improve these processes and try to move to more and more self-administration via the internet. But it lacks transparent processes and planning. Optimizing these processes could be an improvement that is helpful to reduce time and money wasted. Also, it is of greater comfort for the citizens. A more important step could be the move to “free energy.”

If we change the power of the used electricity to a non-harmful level (which is possible!) or move to D.C. (direct voltage) which is not harmful to the people, then we can introduce a “free power.” Free power means the distribution of power energy without the requirement of cables. To move to D.C. power at all is no problem if someone with excellent planning skills does. The people could not be harmed from D.C in such a scope as the alternating voltage does. Thomas Alva Edison ‘s problem was the distribution of electric energy through long distances, so he and Tesla moved to A.C. as a workaround. Also, the industry would earn money from electricity.

If we have free electricity in the environment, the electricity-producing companies cannot count them. We can improve the voltage of electricity to gain higher distances from D.C. After the introduction of free energy, we can use this as fuel for urban regions. The public transportation system could be powered by that fuel. Also my former boss, and now friend developed a system for self-supporting street lights. They need no cable and connection to whatsoever. The lamp gives light for about three days also without direct sun emission. It could help to reduce the high costs in more rural regions. Also, it saves energy costs.

3. Not only one solution could work in my country, but all of the solutions are also possible for my town and country.

Like the public transportation system. If the public transit system did work more efficiently, the more people would use this transport system.

If more people use public infrastructure, also the costs go down. My county has a lot of little towns with long distances to the next town – the problem is bus transport is not efficient. A few decades before, every small town had a train connection. The problem is that they now removed the most train connections. Fewer train stations – fewer users. But the decision-makers do not understand this simple rule of business.
