Polycentric networks

Last updated

In public policy a polycentric network is a group of distinct local, regional, or national entities that work co-operatively towards a common goal. Proponents claim that such networks can better adapt to changing issues collectively than individually, thus providing network participants better results from relevant efforts.

Urban contexts

Robert Kloosterman and Bart Lambregts define polycentric urban regions as collections of historically distinct jurisdictions that are administratively and politically independent. These jurisdictions are in close proximity and well connected through infrastructure. [1] The literature on polycentric urban regions is limited and unconsolidated, [2] so diverse concepts exist. [3] Evert Meijers claimed that polycentric network are especially prominent in Europe.

Rural polycentric networks are nearly non-existent. Urban polycentric networks draw heavily on economic network theories. [3] According to Meijers, “individual cities in these collections of distinct but proximally-located cities relate to each other in a synergetic way, making the whole network of cities more than the sum of its parts”. [3]

Implementation

Polycentric networks have different spatial characteristics, reflecting a micro, meso, or macro-level of connections in a given region. These different scales allow flexible and convertible networks for spatial planning in complex regions and systems.

Metropolitan areas

In metropolitan areas, the scale and intensity of collaboration is a key determinant of whether or not polycentric networks function properly. Metropolitan planning organizations (MPOs) have given researchers a unique opportunity to study the scale and intensity of collaboration. A 2015 study of 381 MPOs in the United States, found a direct link between the MPO's scale and performance. The study concluded that more intense MPO collaboration across both vertical and horizontal stakeholders improved performance. The study found that MPOs that focused more on vertical collaboration (between the state and higher-up agencies) saw a decrease in their perceived performance. The study looked at 15 indicators including condition of transportation network, mobility for disadvantaged populations, air quality, highway congestion, public participation, extent of coordination and stakeholder involvement, satisfaction among general public, satisfaction among local stakeholders, compliance with federal and state rules, transportation systems security, accessibility, reliability, and safety, travel demand model accuracy and project implementation.

Future polycentric networks

Researcher Perry Yang claimed that the future for polycentric networks lies in sustainability. Yang conducted research in Singapore around cities' push for greater sustainability. With globalization and the separation of land[ clarification needed ] come split ecosystems and habitat changes to build infrastructure for human development. [5] A big issue for sustainability is how to minimize human environmental impact while thriving as a species. [5]

Yang’s research explored Singapore's growth over time. He noted that this growth was largely industrial and revolved around rapid mass transit (MRT), which connects areas of the island. [5] The general shift seen in Singapore can be seen as the impact of polycentric networks throughout the island with the implementation of rezoning policies. [5] [ vague ] From 1986 to 1994, much rezoning occurred due to changes in land use policy. [5] Yang found that transit and raw materials are central to growth in rapidly developing areas [5] and argued that Singapore is a good example of a polycentric urban form, but may not be adequate to establish an urban sustainability model.

Regional planning deals with the efficient placement of land-use activities, infrastructure, and settlement growth across a larger area of land than an individual city or town. Regional planning is related to urban planning as it relates land use practices on a broader scale. It also includes formulating laws that will guide the efficient planning and management of such said regions. Regional planning can be comprehensive by covering various subjects, but it more often specifies a particular subject, which requires region-wide consideration.

Urban economics is broadly the economic study of urban areas; as such, it involves using the tools of economics to analyze urban issues such as crime, education, public transit, housing, and local government finance. More specifically, it is a branch of microeconomics that studies the urban spatial structure and the location of households and firms.

<span class="mw-page-title-main">Metropolitan planning organization</span> Transportation committees

A metropolitan planning organization (MPO) is a federally mandated and federally funded transportation policy-making organization in the United States that is made up of representatives from local government and governmental transportation authorities. They were created to ensure regional cooperation in transportation planning. MPOs were introduced by the Federal-Aid Highway Act of 1962, which required the formation of an MPO for any urbanized area (UZA) with a population greater than 50,000. Federal funding for transportation projects and programs are channeled through this planning process. Congress created MPOs in order to ensure that existing and future expenditures of governmental funds for transportation projects and programs are based on a continuing, cooperative, and comprehensive ("3-C") planning process. Statewide and metropolitan transportation planning processes are governed by federal law. Transparency through public access to participation in the planning process and electronic publication of plans now is required by federal law. As of 2015, there are 408 MPOs in the United States.

Urban morphology is the study of the formation of human settlements and the process of their formation and transformation. The study seeks to understand the spatial structure and character of a metropolitan area, city, town or village by examining the patterns of its component parts and the ownership or control and occupation. Typically, analysis of physical form focuses on street pattern, lot pattern and building pattern, sometimes referred to collectively as urban grain. Analysis of specific settlements is usually undertaken using cartographic sources and the process of development is deduced from comparison of historic maps.

Mesoeconomics or Mezzoeconomics is a neologism used to describe the study of economic arrangements which are not based either on the microeconomics of buying and selling and supply and demand, nor on the macroeconomic reasoning of aggregate totals of demand, but on the importance of the structures under which these forces play out, and how to measure these effects. Mesoeconomics, as a science, began to take shape back in the 19th century. Among the researchers, the most notable contribution to the development of problems of regional economic theory, issues of the location of production forces and the efficiency of regional production was made by German economists - Johann Heinrich Thünen, Alfred Weber, Walter Kristaller, August Lesch, professor of economics at the University of Pennsylvania Walter Isard, French economist Jean Chardonnay, American economist of Russian origin Vasily Leontiev, V. Thompson, T. Palander, as well as the authors of the famous textbooks H. Armstrong and J. Taylor. Among Soviet researchers of the first half of the 20th century, G.M. Krzhizhanovsky, I.G. Alexandrova, V.V. Kuibyshev, N.N. Nasrudin Nasri, who dealt with long-term planning and economic zoning. Among the Russian scientists of the second half of the 20th century, research in the field of regional distribution, the creation of territorial production complexes and the efficiency of regional production: T.S. Khachaturova, Ya.G. Feigina, N.N. Nekrasov, A.G. Granberg, P.M. Alampieva, E.B. Alaeva, K.N. Bedrintseva, G.I. Granik, F.D. Zastavny, R.S. Livshits, K.I. Klimenko, Yu.K. Kozlova, A.M. Korneeva, V.V. Kistanova, A.G. Omarovsky, N.N. Oznobina, V.F. Pavlenko, M.M. Palamarchuk, Yu.G. Saushkina, E. D. Silaeva, N.I. Shraga and V.M. Torosov. Several books on this topic, including the book by V.M. Torosov. "Mesoeconomics" of 2004, Mann 2011 [2] and Eng 1987, [3] most accurately determine the field of application of mesoeconomics. As of 2014, 474 articles and books have been written on this topic.

Interreg is a series of programmes to stimulate cooperation between regions in and out of the European Union (EU), funded by the European Regional Development Fund. The first Interreg started in 1989. Interreg IV covered the period 2007–2013. Interreg V (2014–2020) covers all 27 EU member states, the EFTA countries, six accession countries and 18 neighbouring countries. It has a budget of EUR 10.1 billion, which represents 2.8% of the total of the European Cohesion Policy budget. Since the non EU countries don't pay EU membership fee, they contribute directly to Interreg, not through ERDF.

<span class="mw-page-title-main">Micro-sustainability</span> Individual or small scale sustainability efforts

Micro-sustainability is the portion of sustainability centered around small scale environmental measures that ultimately affect the environment through a larger cumulative impact. Micro-sustainability centers on individual efforts, behavior modification, education and creating attitudinal changes, which result in an environmentally conscious individual. Micro-sustainability encourages sustainable changes through "change agents"—individuals who foster positive environmental action locally and inside their sphere of influence. Examples of micro-sustainability include recycling, power saving by turning off unused lights, programming thermostats for efficient use of energy, reducing water usage, changing commuting habits to use less fossil fuels or modifying buying habits to reduce consumption and waste. The emphasis of micro-sustainability is on an individual's actions, rather than organizational or institutional practices at the systemic level. These small local level actions have immediate community benefits if undertaken on a widespread scale and if imitated, they can have a cumulative broad impact.

The Sustainable Communities and Climate Protection Act of 2008, also known as Senate Bill 375 or SB 375, is a State of California law targeting greenhouse gas emissions from passenger vehicles. The Global Warming Solutions Act of 2006 sets goals for the reduction of statewide greenhouse gas emissions. Passenger vehicles are the single largest source of greenhouse gas emissions statewide, accounting for 30% of total emissions. SB 375 therefore provides key support to achieve the goals of AB 32.

Level of analysis is used in the social sciences to point to the location, size, or scale of a research target. It is distinct from unit of observation in that the former refers to a more or less integrated set of relationships while the latter refers to the distinct unit from which data have been or will be gathered. Together, the unit of observation and the level of analysis help define the population of a research enterprise.

<span class="mw-page-title-main">Head/tail breaks</span> Algorithm

Head/tail breaks is a clustering algorithm for data with a heavy-tailed distribution such as power laws and lognormal distributions. The heavy-tailed distribution can be simply referred to the scaling pattern of far more small things than large ones, or alternatively numerous smallest, a very few largest, and some in between the smallest and largest. The classification is done through dividing things into large and small things around the arithmetic mean or average, and then recursively going on for the division process for the large things or the head until the notion of far more small things than large ones is no longer valid, or with more or less similar things left only. Head/tail breaks is not just for classification, but also for visualization of big data by keeping the head, since the head is self-similar to the whole. Head/tail breaks can be applied not only to vector data such as points, lines and polygons, but also to raster data like digital elevation model (DEM).

A circular economy is an alternative way countries manage their resources, where instead of using products in the traditional linear make, use, dispose method, resources are used for their maximum utility throughout its life cycle and regenerated in a cyclical pattern minimizing waste. They strive to create economic development through environmental and resource protection. The ideas of a circular economy were officially adopted by China in 2002, when the 16th National Congress of the Chinese Communist Party legislated it as a national endeavour, though various sustainability initiatives were implemented in the previous decades starting in 1973. China adopted the circular economy due to the environmental damage and resource depletion that was occurring from going through its industrialization process. China is currently a world leader in the production of resources, where it produces 46% of the worlds aluminum, 50% of steel and 60% of cement, while it has consumed more raw materials than all the countries a part of the Organisation for Economic Co-operation and Development (OECD) combined. In 2014, China created 3.2 billion tonnes of industrial solid waste, where 2 billion tonnes were recovered using recycling, incineration, reusing and composting. By 2025, China is anticipated to produce up to one quarter of the worlds municipal solid waste.
