The Sustainable Development of Urban Infrastructures
1. INTRODUCTION
To develop and renew the urban infrastructure is a great challenge in 21th century. In Chengdu, the air quality is always terrible, which can cause some problems of citizens’ health and many cities in China have a inefficient transport system that cause large-scale traffic jam at the peak time. Chinese cities are covered with grey polluted haze and annoying voice from cars. All these problems are from the insufficient urban infrastructures. It is obvious that the necessity of improving, regenerating and advancing urban infrastructure is shown. Restoring and improving urban infrastructure is a vital way to improve the quality of citizens’ lives in cities. Environmental, financial and transport problems are the main challenges of regenerating and advancing urban infrastructure, which can be solved by government intervention and environmentally friendly strategies.
2. WHAT MAKE URBAN INFRASTRUCTURES SO IMPORTANT
Urban infrastructure almost includes everything in a city. It is urban infrastructure that ensures the stable operating of industry, qualities of citizens’ lives and efficient running of societies [1]. Transport system is of great importance. Bad traffic can cause many inconveniences to people and lessen the efficiency of physical distribution. Furthermore, roads are the blood vessels of economy. Without a well-designed traffic system, it is difficult to increase the fortunes of a city. Besides,
Rapid urbanisation has caused a variety of problems, including transport congestion, lack of sufficient homes and living conditions, sanitary and health care issues, and crime. For all these problems, city planners have attempted potential solutions, each with varying degrees of success. Cities including London, Manila and Mumbai have several of the aforementioned problems, and have each tried their own potential solutions. This essay will discuss how successful these schemes have been in resolving these issues.
Public transportation includes buses, light rail, subways, commuter, trains; streetcars are vehicles efficiency and high reliability (www.apta.com ). Furthermore, many cities are trying to invest in public transportation to put serve the needs better and provide more in contrives for citizens particular low-income households and student. Public transport services become attract, which can lead to reduce money by many people. Besides, on an individual level, public transportation saves money, and provides people with choices, freedom and opportunities (Schofer2015).Public transportation also helps to reduce road congestion and travel times, air pollution, and energy and oil consumption( Kyte2011).Public transportation provides fresh air, driving safety, active and reducing stress( Mickey2013).The newspaper of engineer Australia said that transportation demonstrates the vital interconnection of economic development, ecological conservation and attainment of an acceptable quantity of lie in achieving sustainability ( www.engineersaustralia.org.au. It develop not only economy but also fosters spending on others with low-income worker, elderly rural resident and children makes the trip to work and school (Criden 2008). Therefore, this paper with purpose all people
When I was five years old I began school. In Kindergarden we learned basic things like letters, numbers, and how not to be fully engulfed in flames. For some reason, 2004 was the height of anti-fire education in Missouri and before I knew how to tie my shoes I knew that if I ever was ablaze, to cover my face, fall to my knees, and roll back and fourth. This is what my institution placed serious value upon and because I was a student of that institution I also placed serious value upon it. The same idea must be applied to a university's teaching of environmental sustainability. This is discussed in David Orr's "What is Education For?" Through choosing a curriculum a university chooses what it places value onto, by making the environment a priority it showcases to the future generations that environmental wellness is an important responsibility for them to take ownership.
From the past 18th century to the present 21st century. The developments and improvisation in all primary and secondary sectors brought humans under one urban roof, where things are easy to access ranging from sanitation to electricity and internet. The world’s urban population has increased form 733 million in 1975 to 2,857 million in 2000 and is estimated to reach 4,945 million by 2030 (storage). This pattern over the past 50 years gives us an insight about the net gain in urban population. Urban dwellings has transformed current cities into mega cities with population emerging up to 10 million. This rapid urbanization growth brings us a question about transportation. According to the information provided by PRB the number of megacities increased from 4 in 1975 to 22 in 2015(PRB). This trend indicated that in future there will be more cities entering into megacity categories, where the need for development of public transport sectors. Every two people in United States now have a car. If this is going to continue there would be 5.3 billion cars on roads by
With the idea of sustainability in terms of the environment and renewable resources being discussed more often, the idea of social sustainability encroaches its way into all of these topics. With questions such as: how will a city manage this? How will enforcement of sustainability affect our lifestyles? Will people actually willingly follow these ideas of sustainability? These questions show the concern people have for society and this new idea of a sustainable lifestyle. However, people will end up not following these new guidelines to a more reserved and environmentally aware lifestyle, which in turn leads to the question: are they really valuable to society? Ethically speaking, no these people are not valuable, because in turn,
The development of every nation hinges on the effectiveness of their transportation systems. Movement of goods, services and people to and from work is made possible by transportation systems. The importance of effective transportation systems cannot be over-emphasized. A lot of countries are facing Transportation problems and my country Ghana is no exception. A trip of about 30 minutes can take about an hour or more due to traffic jams. This is seriously impacting productivity and has been a topical issue in the country. The situation is the same in Uganda where I currently work. To this end, Transportation Engineers are needed to design roads/ highways that will stand the test of time, plan effective traffic management systems to reduce travel
Sustainability is a topic that has become very important in recent years. Sustainability is defined as, “the ability to continue a defined behavior indefinitely.” ("Finding and Resolving the Root Causes of the Sustainability Problem", 2014)
Sustainable development, when applied to the development of a system, creates complexity for the stakeholders involved in and affected by that development. To delve this complexity, solid definitions must be proposed for development and sustainable development in order for a framework to be established through which these complexities can be understood. Furthermore, these definitions are necessary evils for explorations of the intricacies of sustainable development due to the various paradigms used to define “development” and “sustainable development.” One definition of development, and the one that will be utilized within this report, is the, “utilizing resources to advance the complexity of a whole society.” From this, a definition of
In his book, The Age of Sustainable Development, Jeffery Sachs begins with the role of technological change in sustainable development. Sachs uses the Maglev in Shanghai as an example of how technological change can help with sustainable development. It improved transport services and energy efficiency, eventually enabling a shift to a clean low carbon system. Instead of being powered by finite resources such as coal or petroleum, the Maglev is powered by electricity. In most cases states are resistant to adopt practices that encourage sustainable development because they believe it will hinder their economic growth. However, with technological advances such as the Maglev, states have incentives to change because it increases
Goal 14 addresses the issue of conserving and sustainably using the oceans, seas and marine resources for sustainable development (United Nations, 2015). There are seven targets that are used to achieve success for this goal. The targets that are truly measurable are targets 14.1, 14.3, 14.5, 14.6 and 14.7. Target 14.1 is truly measurable because firstly, marine pollution in the form of debris visibly fills the oceans and seas and can therefore be tracked to see how the amount changes with every year. Nutrient pollution causes algal growth in waterways and the algal growth can be measured to provide information on the amount of nutrient pollution in a water body. Target 14.3 is measurable because oceans’ pH levels can be measured and monitored to collect data over time. Assuming that target 14.5 is referring to 10% of the entire world’s coastal and marine regions, it is measurable. Target 14.6 is measurable because fisheries subsidies are forms of government intervention that have economic value. Since financial transfers from the government are involved, they should be recorded. Since target 14.7 focuses on the economic benefit of Small Island Developing States and Least Developed Countries, it can be measured by looking at the specific economic activity and comparing it to previous years.
It is obviously to see that there is a lot of traffic congestion in big cities these days.However, solving this problem is not easy at all.In my opinion we have to do three immediate measures in order to solve the traffic problem in my city and in other cities as well.First of all, we should encourage people to use public transport,because public transport can carry a lot of people compared with private vehicles, so we can
Traffic congestion is a term whereby congestion is mentioned as “clog”, “impede” and “over utilised”(http://ops.fhwa.dot.gov/congestion_report/executive_summary.htm#what_is_congestion). This term is used to describe a traffic situation is with enormous amount of vehicle on the roadway, causing the flow of vehicle to be inefficient. In another word, number of traffic is higher than the supply (capacity) of current highway facilities will cause traffic congestion (Wan Hashim Wan Ibrahim 2009). According to IBM, its research states that a growth of 20% of the U.S nation population between 1982 and 2001 leads to a leap of traffic congestion for about 236%. Therefore, there is no doubt that urbanisation of an area where population density is too high will cause traffic congestion to occur. As time goes on to present days, this issue arises as one of the obstacles that brings negative impacts to the urbanized world namely retarding the efficiency of economic activities and emergency vehicles in operations, waste of time and mental torture while in a traffic jam, wastage of fuel consumption which leads to pollution, and road rage. As to make a better world, this issue must be eliminated by implementing ways to manage this problem.
Cities like Delhi, Mumbai, Kolkata, Chennai, Patna, Lucknow etc, they all have to deal with this common problem of traffic. They have to deal with thousands of cars running through the streets each day. They share same problem of traffic and the reason behind the problem is also same; increasing number of cars on streets, poor road management, poor practices on behalf of employers etc.
The objective of this paper is to understand the modes of road transportation, the role of road transportation in urban areas, the role of transportation infrastructure in
Studies show that people experience a dip in interest and concern about environmental problems during their adolescent years (age 13-17). However, there is a lack of information on whether this dip applies to the other two dimensions of Sustainable Development (SD) i.e. social and economic, as well. This study examined changes in the broader concept of Sustainability Consciousness (SC) throughout adolescence. SC is defined as “a composite of knowingness, attitudes, and self-reported behavior related to each of the three dimensions (environmental, social, and economic) of SD.” Using an age-adapted questionnaire, the investigators surveyed more than 2,400 students
