Urban ecologyUrban ecology is the scientific study of the relation of living organisms with each other and their surroundings in an urban environment. An urban environment refers to environments dominated by high-density residential and commercial buildings, paved surfaces, and other urban-related factors that create a unique landscape. The goal of urban ecology is to achieve a balance between human culture and the natural environment. Urban ecology is a recent field of study compared to ecology.
Chinese economic reformThe Chinese economic reform or Chinese economic miracle, also known domestically as Reform and Opening-up (), refers to a variety of economic reforms termed "socialism with Chinese characteristics" and "socialist market economy" in the People's Republic of China (PRC) that began in the late 20th century. Guided by Deng Xiaoping, who is often credited as the "General Architect", the reforms were launched by reformists within the ruling Chinese Communist Party (CCP) on December 18, 1978, during the "Boluan Fanzheng" period.
Sustainable urbanismSustainable urbanism is both the study of cities and the practices to build them (urbanism), that focuses on promoting their long term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. Well-being includes the physical, ecological, economic, social, health and equity factors, among others, that comprise cities and their populations.
Urban sociologyUrban sociology is the sociological study of cities and urban life. One of the field’s oldest sub-disciplines, urban sociology studies and examines the social, historical, political, cultural, economic, and environmental forces that have shaped urban environments. Like most areas of sociology, urban sociologists use statistical analysis, observation, archival research, U.S.
UrbanizationUrbanization (or urbanisation) is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Urbanization is often responsible for the myriad of modern problems facing humanity.
Urban renewalUrban renewal (also called urban regeneration in the United Kingdom and urban redevelopment in the United States) is a program of land redevelopment often used to address urban decay in cities. Urban renewal involves the clearing out of blighted areas in inner cities to clear out slums and create opportunities for higher class housing, businesses, and other developments. A primary purpose of urban renewal is to restore economic viability to a given area by attracting external private and public investment and by encouraging business start-ups and survival.
History of BeijingThe city of Beijing has a long and rich history that dates back over 3,000 years. Prior to the unification of China by the First Emperor in 221 BC, Beijing had been for centuries the capital of the ancient states of Ji and Yan. It was a provincial center in the earliest unified empires of China, Qin and Han. The northern border of ancient China ran close to the present city of Beijing, and northern nomadic tribes frequently broke in from across the border.
Urban renaissanceThe urban renaissance of the United Kingdom is the recent period of repopulation and regeneration of many British cities, including Birmingham, Bristol, Cardiff, Glasgow, Leeds, Liverpool, Manchester, and parts of London after a period of inner city urban decay and suburbanisation during the mid-20th century. The most common equivalent term used in North America is New Urbanism. Urban regeneration was achieved through a number of initiatives including tax incentives and the lifting of some urban planning restrictions, as well as positive state intervention encouraging business and residents back into city centre areas.
Space Shuttle programThe Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011. Its official name, Space Transportation System (STS), was taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. It flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips.
CounterurbanizationCounterurbanization, or deurbanization, is a demographic and social process whereby people move from urban areas to rural areas. It is, like suburbanization, inversely related to urbanization. It first occurred as a reaction to inner-city deprivation. More recent research has documented the social and political drivers of counterurbanization and its impacts in developing countries such as China, which are currently undergoing the process of mass urbanization. It is one of the causes that can lead to shrinking cities.
