Sustainable Cities One of the most extreme and rapidly growing anthropogenic pressures on the natural world is urbanization. The process of urbanization has been dynamic playing out over multiple scales of space and time. According to complexity theory, cities have been interpreted as complex, dynamics, self-organizing systems that are continually changing under pressures of certain factors due to internal processes and external factors (Galderisi). Urban areas have been growing twice as fast as urban population (Karen C. Seto). Urbanization, however, varies significantly across countries. Some of the major trends witnessed in urban areas include; - spatial growth of urban areas faster than urban population, modification of both local and …show more content…
Energy demands, wastes, buildings, water services and industrial process are an outcome of urbanization (Frank Nevens). Some of these issues tend to affect human population either directly or indirectly. For example, the growth of built up areas in cities have contributed to a climatic phenomenon, urban heat island, which is explained as the condition whereby cities experience warmer temperatures than the surrounding rural areas. This has resulted in heat-related health problems thus raising concern among researchers and human being as a general. There are other severe environmental problems that are likely to occur in cities. Industries within cities have contributed to poor water and air quality (Maria João Alcoforado). Fumes released into the atmosphere contaminates the air and when inhaled may cause respiratory problems. There are also industries that release their waste into water sources such as rivers thus tampering with the aquatic eco-system. Some industries also cause noise pollution thus causing disturbance to people residing around such areas. Other than industries, exhaustive fumes from vehicles have also contributed to the pollution of air with increased number of motor vehicles in urban areas. These vehicles introduce carbon dioxide into the atmosphere making it dangerous for human existence. Urban areas have also been considered to be the primary source of greenhouse gas emissions which account for more than 70 percent of global greenhouse gases that are
Task #1 : Analyse the impacts of at least two urban dynamics operating in a large city of the developed world.
All in all the industrial revolution had a positive effect on society, accomplishing things many do not realize and creating a turn of events that would put the USA as the world power. New farming methods meant better diets, which lead to lower death rates. Efficient and useful inventions, as well as machinery, made it easier for people to work, and made more job opportunities, as well as enjoyment in the workplace. More and easier ways of travel became commonplace, such as railroads. In addition, as cities began to grow, streetlights provided safety at night, and our economy grew greatly. While some might argue that Industrialization had primarily negative consequences for society because it caused children to be used as workers and made school
Urbanization is a concept that is deeply rooted in the increase in a population within a region in response to the availability of unique opportunities. The opportunities may include the availability of employment chances in factories, investments opportunities in the urban areas, and the presence of sufficient housing and social infrastructure. It is apparent that urbanization began centuries ago in different regions of the world. However, the development of suburban areas has also been an interesting phenomenon over the centuries. Initially, people strived to live in the luxurious houses in major towns and cities. Nevertheless, there was a gradual shift in the desire to live in the cities when various negative impacts of overpopulation
Urban development is the social, cultural, economic and physical development of cities. The development of cities is the main topic of human geography. Urban development can be used in different ways by the researchers. It can cause the price of things to increase fast. Urban development occurs in major cities like New York City, Tokyo, Japan. Urban development started back in the earlier cities like Mesopotamia, Egypt. This spreads the culture that affect people which makes them want to go to the major cities. Over fifty percent of the earth’s population lives in urban areas. Studies show by 2045 that the number of people living in a urban area will increase.
Urban sprawl has contributed greatly to air and water pollution as well as increased water and energy consumption. Since urban sprawl places people outside of walking distance to shopping areas and work areas, they are forced to rely heavily on cars for everyday transportation. This over reliance on vehicles has contributed significantly to air pollution and greenhouse gases becoming more abundant within the planet’s atmosphere. Pollution from vehicles is often the number one cause of pollution in many urbanized cities, such as Los Angeles. Another thing to take into consideration are the recent heat waves that have been experienced in the past few summers across the nation. People fail to realize that urban sprawl and pollution, which is a by-product of urban sprawl, have contributed significantly to the higher temperatures large cities have experience over the last few years.
Poor air quality is associated with some health issues from the short-term problems to severe
In the modern world, human civilization has seen many changes from earlier points in our history. In the more developed countries in the world, human civilization is broken up into two main categories known as “Urban Sprawl” and “New Urbanism”. In the interactive, Urban Sprawl and New Urbanism are broken down into five main branches: Regional Transportation, Parking, Street Plans, Shops, Civic Buildings, & Workplaces, and Residential Distribution. These branches reflect many of the places that we live in and see every day, and explains their purpose in depth.
There are many differences between organic vineyards and non-organic vineyards like for example, organic vineyards produce their wine excluding the use of artificial chemical fertilizers, pesticides, fungicides and herbicides while non-organic vineyards on the other hand do produce their wine applying those products. Every year that passes our generation is becoming more and more advanced in many things, including the usage of organic products. Many things sold at groceries stores are now available organically, like fruits and other types of nourishments and soon many things will be made organically. The pros and cons of non-organic and organic vineyards both have good arguments that can really change the opinions of many people but if you had to chose between one or the other, which one would you pick?
Throughout history, there have been dozens of kinds of civilizations. In said civilizations, there are subsets of districts in which only certain sets of people reside. Between World War I and now, many changes in these areas have occurred that we can observe. Whether it be a strong economy, rapid postwar growth, change in class, or simply new architectural designs for cities, there are several factors that contributed to the rise of what we now know as suburbia.
Urbanization can be seen from various sociological perspectives such as the functional perspective and the conflict perspective. Functionalist’s view “on urbanizations generally focus on the ecology of the city”. On the other hand, the “conflict perspective tends to focus on political economy”. Human ecology “is a functionalist field of study that looks at on the relationship between people and their built and natural physical environments”. A specific model that displays this is the concentric zone model, it “views a city as a series of concentric circular areas, expanding outward from the center of the city, with various “zones” invading adjacent zones”. In opposition, the conflict perspective consists
According to the data from United Nations urbanization prospects 2014, in the early 20th century the urbanized population only accounted 15 percent of the world’s total population. Half century later the pace of urbanization rate accelerated and the figure reached 30 percent in 1950. After nearly 60 years of development, in year 2008 it was the first time that urban population outstripped rural population. Now in 2014 there has been 54 percent of world’s population become urban dwellers. However due to historical geographical and economic reasons, the level of urbanization varies significantly across regions. Highly urbanized regions include Northern America and Caribbean and Latin America with over 80 percent of their total population urbanized.
Urbanization has been constant over the last few hundred years. It continues even today and will continue with the constant increase in world population. Urbanization affects all levels of society and an accommodating urban environment is a necessity. But as humans we haven’t really been good at it. The process of urbanization can vary by country. Within the urban communities the political economy determines the existence of social classes.
The process of urbanization first began in the more developed regions of the contemporary world. Almost a century ago, 1920 saw below 30 per cent of the ‘developed world’ in living urban areas. Only decades later, over half of their populace were residing in urban areas. Today, the
The complex processes of urbanisation overarches and entails a set of social, cultural, economic, political, environmental and technological functions that result in sprawl and densities, proportional to core size and settlement. Further implicating the extensive use of natural resources from fringes and rural spheres within city limits to be consumed and then later in turn converted into waste. Urban ecosystems are therefore, complex multifaceted systems that require a burdensome amount of natural resources input and negotiations for their adequate development. In urban discourse, the lack of interdisciplinary and trans-disciplinary interest partly due to an absence of tools to which all disciplines can use to further incorporate ecological theories to assessment and planning of urban centers. All these connections have been made and academics have divided the complex concept into biophysical processes and socioeconomic processes when examining cities in case studies. The urban ecology theory and a closely related concept of urban metabolism can explain the technical aspects of urban density and growth but human influences are not accounted for in the assessment. However, human scholarship is a key component that shapes the metabolic processes in urban ecologies and in turn alters the initial footprint.
The process of people moving into cities, which is called urbanisation, was happening around the world in past decades. It causes cities to have more labourers and resources than before. This makes a big contribution to the social development of cities. Thanks to these social developments, public services are becoming better in these areas. Citizens can enjoy a better life by access these public services such as better medical care, more education resources and well-built transport. It means an equitable society can be created. An equitable society means citizens can have more opportunities to access social resources and to live a better life. This essay will argue that
