Edx Cities and the Challenge of Sustainable development Urbanization and decentralization

I agree with the idea that decentralization of population should be promoted simultaneously with urbanization. It is imperative in the case of my country Japan, where impacts of global warming have stated to bite and disasters like typhoons and floods have devastated many rural areas over the past two years. Since disasters tend to hit the same areas and climate change is likely to make them more severe, and since reconstruction of disaster-stricken areas takes time due to huge national government debts, what follows would be influx of population to urban areas, mainly to Tokyo, which already has about one-tenth of the total population. Meanwhile, great earthquakes right under Tokyo and in the Nankai region, another highly concentrated area, are predicted to occur at the rate of 70 % in 30 years. Improving infrastructures of middle-sized regional cities could mitigate the ensuing problems.

Edx Cities and the Challenge of Sustainable development Part 5

Overcoming social divide is essential in sustainable development. Well-planned infrastructure  and layout can avoid social divide. It realizes shared economy, which gives mobility to everyone and allow everyone to use public and private services. People can rent places to live in without much money, so that communities will be more diverse. Sustainable transportation system will get rid of automobiles and revitalize urban communities. Cities, with universities, are where innovation happen. In two decades, not only already developed areas but also Africa, south Asia, Latin America, and other parts of the world will also have hubs for innovation. Cities are where cutting-edge businesses tie up with universities conducting advanced researches. Cities will nurture higher education and businesses, which will create jobs and tackle climate change. This will make it possible for humans to attain SDGs.
  • How can cities, as mixed-use environments, continue to foster the growth of universities and similar centers of learning and innovation? Why are these knowledge centers found most often in urban settings? What does this mean for the development of sustainable cities? - New ideas and products developed in cities, especially at universities, are used to improve the lives of those not only in cities but also in the countryside. With strong infrastructure and abundant resources, cities also provide stable environment for researches. Thus necessity to cope with the common challenge of the mankind will naturally make cities foster the growth of universities and other institutions.

  • How can the internet and the network of e-Everything connect these centers of innovation to create more sustainable solutions across larger physical and social distances? How can this collaboration help to achieve the goals of social inclusion, economic prosperity, and environmental sustainability? -The internet and the network of e-Everything streamline, and save, the use of energy and other resources and make shared economy possible. Electric cars and MaaS (Mobility as a Service) will reduce greenhouse gas emissions and allow people  start commuting to or living near their work places with little or no capital. The Internet and e-Everything will also provide more opportunities for those who are disadvantaged by allowing them more access to public services. In education, wiping out digital divide means giving equal opportunities to all children. These more sustainable and more inclusive societies will make more people happier and this will lead to economic development and higher environmental sustainability.

Edx Cities and the Challenge of Sustainable development Part 2

Why cities? The importance of SDG 11

More than half of the world population live in cities. The population in cities around the world surpassed that in rural areas sometime around 2007 because urbanization is a very deep part of economic development.

Now 55 % of us live in urban areas and by the year 2050, 70 % of us will be in urban areas. Cities are important because they are where most of us live and preponderance of economic activities takes place. Economies develop from those based in rural areas to those based in urban areas and populations increase in urban areas. Productivity is higher in urban areas than in rural areas. About 75 to 80 % of annual income is generated in urban areas.

Because of high agricultural productivity, most of the labor force will become industrial. Now around 70% of a country is in cities all over the world except in Asia and Africa, where the situation will be the same in two or three decades. Another 2.5 million people will be in urban areas by 2050. There will be mega-cities with tens of millions of population. Moat of the high-income cities will not be in Africa and Asia. Making sure that new mega-cities in Asia sustainable is essential.

SDGs are to be used for it. Professor Saches refers to the wisdom of John F. Kenedy on goal setting, that is, gpal-setting is a way to inspire people, and make all of us work together towards the objective of our well-being: "By defining our goal more clearly, by making it seem more manageable and less remote, we can help all peoples to see it, to draw hope from it, and to move irresistibly towards it." Professor Saches likes the idea by making the goal more manageable, then we help people to see that the goals are not just empty words but something that is within reach.

SDG 11 and other related goals need to be made more manageable and less remote, so that people can draw hope from them, and all parts of the world move irresistible move towards them.

Homework
  • How does the rise in urbanization impact sustainable development? How does it impact specific areas of sustainable development such as land-use change, global emissions, social equity and more? - Cities are where more than half the world's population live and urban areas use most of the energy and produce most of the waste products. Urbanization change farms and ranches into industrial and commercial districts and emit a large amount of CO2. It makes income gaps wider and lower the quality of a large part of the population.
  • How does globalization and the increasing interconnection of societies and trade across the world affect the growth of mega-cities? - Today's cities are intertwined through trading, and this help them grow together, avoiding conflicts and wars, although this interconnectivity can adversely affect in times of recession or serious disasters.

Edx Cities and the Challenge of Sustainable development Part 1

17 Sustainable Development Goals up through the year 2030 were set by UN on September 25th, 2015, followed by the Paris Climate Agreement, whose goal is to counteract global warming.

The three core objectives of SDGs are economic progress, social inclusion, and environmental sustainability.

Learning 17 SDGs by heart is homework Professor Sachs would like to give to the world.
SDG 1 is to end extreme poverty.
SDG2 is to end hunger.
SDG 3 is to ensure universal health coverage and end needless death and suffering from treatable or preventable diseases.
SDG 4 is universal access to education at least through the secondary level.
SDG 5 is to accomplish gender equality.
SDG 6 is to secure enough clean water.
SDG 7 is to create sustainable, clean energy.
SDG 8 is decent jobs for all.
SDG 9 is to promote industry, innovation, and infrastructure especially in developing countries.
SDG 10 is the reduction of inequalities within and among countries.
SDG 11 is to create sustainable cities and communities.
SDG 12 is to realize circular economy, or sustainable consumption and production.
SDG 13 is climate action, or implementing the Paris Clime Agreement.
SDG 14 is to protect life below water.
SDG 15 is to protect life on land.
SDG 16 is to achieve peaceful and just societies.
SDG 17 is for all countries to collaborate to achieve these goals.

SDG 11, urban agenda, runs through all 17 SDGs.

HW
  • What is the role of international agreements, such as the SDGs and the Paris Climate Agreement, in sustainable development? What types of outcomes and actions comes from them? - International agreements raise awareness of the public on the related issues and make people think seriously about them. It promotes the governments, business, and universities to work on the issues. They also bring hope that countries will be able to corporate to attain mutual goals.
  • How could your city be more sustainable? What can you do (take mass transit, recycle, etc.) to lessen your city's impact on the environment and social challenges? - I work in Tokyo. It should stop depending on fossil fuels by installing solar panels on each building and supplying individual generators in preparation for disasters. It has enough public transportation, but it should promote the use of electric cars more. Recycling has been in place, but there should be more to be done for responsible consumption. For example, to reduce or change our use of home delivery services would lessen the burden on truck drivers and the environment. There are systems for consumers to pick up their order at the shop, delivery station, or a designated convenience store. We should use the system more often.
  • What are the benefits and challenges of implementing the SDGs at the city level?  - By implementing the SDGs will improve city life because SDGs are closely related to agendas cities have. Cities have tackled poverty (SDG 1), hunger(SDG 2), health issues (SDG 3), and educational gaps (SDG 4). Cities offer places to attain gender equality (SDG 5) as the urban environment is less conservative. Providing clean water (SDG 6) and sustainable, clean energy (SDG 7) is a basic responsibility of the municipality. Job issues (SDG 8) are mainly the issues of cities, where most of the population gather for a decent job and a better life. Innovation occurs in cities and infrastructure is the foundation of the function of a city (SDG 9). The gap between the rich and the poor is severe in cities, so reduction of inequality (SDG 10) is the permanent agenda of cities. Sustainable city (SDG 11) is SDG of the city itself. Circular economy (SDG 12) is important for the future city economy. Softening the impacts of global warming (SDG 13) such as tackling the sea level rise or protecting life below water  (SDG 14) and life on land (SDG 15) is necessary to maintain cities, especially in food supply. Peaceful and just society (SDG 16) should be realized in cities as most people live there and for all these issues to be achieved, the world have to collaborate (SDG 17) to achieve the goals. In terms of drawbacks, securing enough budget will be the challenges of implementing the SDGs. Probably the vicious cycle is there: inability to work on SDGs due to small budget which is due to impacts of climate change and unsustainable economy. In addition, SDGs that are related to economic progress can be more prioritized over those that are related to inclusiveness and sustainability as has ever been.

Edx Cities and the Challenge of Sustainable development Part 4

  • How can coastal cities prepare for environmental changes such as sea-level rise and increased extreme weather? - One idea is to pump out the sea water, desalt it, and use it for water-shortage problem and/or afforestation. However, this measure consumes a lot of electricity and the salty waste water has negative impacts on the environment according to a BBC podcast report. Another would be to learn from old cities below sea level such as Amsterdam or Venice. Amsterdam uses windmills and Venice is working on a coastal levee. Both ideas are environmentally friendly. The last  is to make huge drainage underground, which is said to have helped save Tokyo during typhoons in 2019 from devastating inundation except for its surrounding areas. Burying power lines underground is important in storm-prone cities to avoid massive blackouts caused by extremely strong winds toppling steel towers and trees, which actually happened in the surrounding areas of Tokyo in 2019.
  • Following the example of the collaboration between Quebec and New York City for hydroelectric power, how can cities work together to create clean energy systems and lower greenhouse gas emissions?- Cities can collaborate in peak-cut by sharing electricity. Some cities are highly industrial and need much electricity in the day time while other cities are more residential and the peak time comes in the evening. Directing extra electricity in some cities to other cities in short of electricity can keep use of resources for generation low. Cities can also share information on electricity consumption trends for the same purpose. 
  • In addition to lowering greenhouse gas emissions, how can mass public transport and the share-economy contribute to economic and social inclusion? -- Mass public transport and the share-economy allow more people to live a fulfilling life by expanding their mobility, which allows them to have a job, go to school, go to hospital, have access to various cultural, sports, or entertainment facilities, take an excursion, and do many other activities that otherwise they cannot. Mass public transport and the share-economy can even grant the world great people. For example, Michael Obama as a teenage girl commuted by bus to a good high school, which was in the distant area from her community, the South Side, Chicago. That high school education allowed her a good university education and the wonderful, inspiring career. For inclusiveness and development of humanity, good access to what a city offers is essential.

SDG 9 Industry, Innovation, and Infrastructure is related  not only to new cities but also old cities that have been experiencing extreme weather events and other disasters. For example, Tokyo had its peripheral areas damaged by typhoons and torrential rains. SDG 10 is important for reconstruction.

HW
  • Think about your city. What energy system does your city currently run on, and what would it take to convert your city's infrastructure to clean, green electricity? -- I work in Tokyo and live in one of the suburbs of Tokyo. The population of Tokyo is 13.94 million and the density is 6,354 as of 2019. Tokyo runs on fossil fuels. It has highly developed train and subway systems, but there are enough cars and trucks to pollute the air, too. Our power plants are run mostly by fossil fuels, which account for about 80 % of all the energy sources for electricity generation as of 2016. Natural energy accounts for around 17 %. Before Fukushima nuclear meltdown, as much nuclear energy as fossil fuels in percentage was used, but most nuclear reactors are not in operation now. What we did about energy shortage right after the power plant disaster was to reduce the use of energy. Electricity usage in some areas was restricted for certain hours a day for a while, and about half of the light bulbs on highways and streets were gone.  Shift to LED was done quickly. Using air conditioners moderately has become a norm. I think Japan should work more on hydroelectric and geothermal energy  sources, for we have a lot of rain and volcanoes. Also, as we have big earthquakes, typhoons, and floods, compact generators in store and solar panels on each building will lessen the damages in the aftermath of a disaster. Some railway companies have started coach seat reservation services to accommodate the needs of the aging suburban inhabitants. This new service is part of their projects in view of Mobility as a Service (MaaS), which will streamline transportation resources while expanding mobility.
Hello, James. Thank you for your response. Your description of the challenge of your city is impressive. Establishing a stable supply of electricity for over 20 million people would require a lot of efforts... I hope Lagos will soon build a sound, sustainable electricity supply system. 

Hello, M-zed. Your picture of future streets is my dream, too. Shared bikes public bike rental systems with maintenance stations would be nice in some communities, too. Young and healthy people will walk or ride a bike, and those who need help can have mobility thanks to self-driving, electric cars. Everyone can enjoy freer, safer, and cleaner transportation in the future.

Hello, HPDejean.  It seems to me that you already live in a sustainable city. Probably the air of your city is much less polluted than that of mine, a city near Tokyo. Clean air makes vegetable gardening and cycling preferable. Shift to clean energy sources opens the door to a happier life.
  • Think about your home or work environment. Imagine a system governed by the Internet of Things. How could you make the appliances and features of that living space work together to create a smarter, greener system? - If some part of the IoT is in short of energy while another part of it has plenty of it or even wasting it, IoT can coordinate the distribution of the electricity. Also, while no one is at home or work, the network of the place can turn itself off maintaining some important appliances like the refrigerator.
  • What can be done to make cities more healthful spaces? Could more parks and plants help to decrease carbon in the atmosphere to make the air more breathable? Can mass public transport and travel by bicycle be encouraged to increase physical activity and decrease pollution?   -  My intuitive guess is that we need a massive amount of green like that of a jungle to decrease carbon in the atmosphere and to make the air more breathable. Also, plants' respiratory systems release CO2 into the atmosphere at night. The reason why we have more oxygen than carbon dioxide in the air is that carbon is buried underground, trapped in waste and dead bodies, which will turn into coal, oil, and natural gas. To stop digging out and burning fossil fuels is imperative for reduction of CO2 in the atmosphere. Therefore, using more public transportation and bicycle should be encouraged. It is good for the health, too, as it makes the air less toxic and our lifestyle less sedentary.

Edx Cities and the Challenge of Sustainable development discussion - Tokyo in 2019

Hello from a country of disasters, Japan. I am taking this course for general knowledge. Concentration of population to Tokyo would be the trend due to climate change although decentralization has been called for in my earthquake-prone country for years. The population of Tokyo is 13.94 million and the density is 6,354 as of 2019, and it is estimated by the government that 23,000 will die if this capital is hit directly by a megaquake, which is long overdue. Also, Tokyo barely escaped having a third of it inundated by water from Typhoon Hagibis this October thanks to a huge drainage the government had prepared, an upstream dam which happened to be empty, and a whim of the typhoon course. Meanwhile, the suburbs and the countryside have already been suffering. While 54,000 evacuees from Fukushima are still scattered around Japan according to the Reconstruction Agency, as unusually strong typhoons and large floods started devastating many areas in this country recently, the number of the displaced will increase. Migration from the countryside to the urban areas cannot be avoided... Speaking of infrastructure, I hope that new cities with many storms will choose to bury power lines. We learned the hard way this year that a typhoon can topple steel towers as well as trees, which then tear down power lines, causing massive blackouts for a few weeks. Although everyone here is for burying power lines, doing it after development costs much. Before I finish, let me share with you two pictures I took at the same spot on the Tama river, which flows along the western border of Tokyo, in 2017 and 2019. They show a fraction of the impacts of the typhoons that Japan has experienced over the past two years.

Sample 1
Main IdeaIt is good for the health to cook yourself.
TransitionFresh and safe ingredients can be used for home meals.
Supporting DetailsFor example, you can buy meat and vegetables at a store of your own choice right before you cook. On the other hand, restaurants often use frozen food, which is not fresh and has chemicals. This is especially true in seasoning. At home, you can make broth using natural food, but restaurants often use ready-made soup stock containing additives and preservatives.
Follow-upTighter regulations on food have made restaurant food healthier than before, but businesses prioritize cutting costs. At least you know what you are eating when you prepare dishes for yourself.
ConclusionBy cooking for yourself, you can make sure that you stay healthy.

Sample 2
Main Idea&Transition Eating out regularly livens up life because it helps you socialize with others.
Supporting DetailsHaving conversation over lunch or dinner surrounded by other relaxed diners helps you see people and life positively. Going to a familiar Chinese restaurant with your beloved makes you feel comfortable. Tying a new Italian dish with your friends is exciting. Each of such times is a precious moment of life.
Follow-upThis habit might seem morally wrong to some people, but eating in restaurants on a regular basis does not mean going out to eat three times a day. Allowing oneself an hour of good mealtime a few times a week is neither an extravagance nor indulgence. It is a lifestyle.
ConclusionMan does not live to eat but eat to live.
