Metropolitan Stockholm (also known as Greater Stockholm or, in Swedish, Storstockholm ), is a metropolitan area surrounding the Swedish capital of Stockholm. Since 2005, Metropolitan Stockholm is defined by official Swedish Statistics as all of Stockholm County . It

200-477: A county -level municipal government structure, with some shared services between a central city and its suburbs, which may or may not include the entirety of a metropolitan area. Population figures given for one metro area can vary by millions. There has been no significant change in the basic concept of metropolitan areas since its adoption in 1950, although significant changes in geographic distributions have occurred since then, and more are expected. Because of

300-677: A city"), plural: aires d'attraction des villes . The official translation of this statistical area in English (as used by INSEE) is "functional area". The AAV follows the same definition as the Functional Urban Area (FUA) used by Eurostat and the OECD , and the AAVs are thus strictly comparable to the FUAs. The AAV replaced in 2020 the metropolitan statistical area called aire urbaine (AU). The AU, which

400-496: A comparable assessment of countries' fiscal policies, promoting transparency and accountability at the international level. In addition, in an econometric study published in the Economic Modelling journal, an analysis on government energy technology spending showed that spending on the renewable energy sector created five more jobs per million dollars invested than spending on fossil fuels . Since sustainable infrastructure

500-426: A connection between cities, transportation for people and goods, and protection for land against flooding and erosion, they only last for 50 to 100 years. Many were built within the last 50 years, which means many infrastructures need substantial maintenance to continue functioning. However, concrete is not sustainable. The production of concrete contributes up to 8% of the world's greenhouse gas emissions. A tenth of

600-493: A contiguous area of spatial units that have at least 15% of their employed residents working in the city. In practice, the parameters of metropolitan areas, in both official and unofficial usage, are not consistent. Sometimes they are little different from an urban area, and in other cases, they cover broad regions that have little relation to a single urban settlement; comparative statistics for metropolitan areas should take this into account. The term metropolitan can also refer to

700-484: A coordinated focus on both creating the methods of transportation themselves and providing them with networks that are equally or more efficient than existing car networks such as aging highway systems. Another solution to transition into a more sustainable infrastructure is using more sustainable materials. A material is sustainable if the needed amount can be produced without depleting non-renewable resources. It also should have low environmental impacts by not disrupting

800-658: A district in Kocaeli province and thus in the jurisdiction of the Kocaeli Metropolitan Municipality, is arguably within the metro area of Istanbul with many of its residents commuting to Istanbul for work and the Marmaray, a commuter rail line, extending into the district. The district however, as previously mentioned, is not a part of Istanbul's provincial limits, and thus not subject to the jurisdiction of its metropolitan municipality. The word metropolitan (municipality)

900-456: A greater megalopolis . For urban centres located outside metropolitan areas that generate a similar attraction at a smaller scale for a region, the concept of a regiopolis and a respective regiopolitan area, or regio, was introduced by German professors in 2006. In the United States, the term micropolitan statistical area is used. A metropolitan area combines an urban agglomeration with

1000-431: A harmonised definition of the metropolitan area, and the goal was to have an area from which a significant share of the residents commute into the city, a concept known as the "functional urban region". France's national statistics office, INSEE , names an urban core and its surrounding area of commuter influence an aire d'attraction d'une ville    [ fr ] (or AAV, literally meaning "catchment area of

1100-577: A high degree of economic and social integration with the core as measured by commuting ties. The OMB then defines a Combined Statistical Area as consisting of various combinations of adjacent metropolitan and micropolitan statistical areas with economic ties measured by commuting patterns. The Office of Management and Budget further defines a core-based statistical area (CBSA) to be a geographical area that consists of one or more counties (or equivalents) anchored by an urban center of at least 10,000 people plus adjacent counties that are socioeconomically tied to

1200-494: A higher level of relative sustainability than their traditional counterparts. In a sustainable city, urban resilience as well as infrastructure reliability must both be present. Urban resilience is defined by a city's capacity to quickly adapt or recover from infrastructure defects, and infrastructure reliability means that systems must work efficiently while continuing to maximize their output. When urban resilience and infrastructure reliability interact, cities are able to produce

1300-522: A metropolitan area, it is sufficient that a city or cities form a nucleus with which other areas have a high degree of integration. A metropolitan area is commonly known and characterized by a high concentration in service sector labor and enterprises. Macroeconomics views metropolitan areas as trade regions of economic significance. The Greater Johannesburg metropolitan area is the fourth largest metropolitan area in South Africa . Its population

1400-467: A normal Italian province. The list of metropolitan areas in Sweden is collated based on statistics of commuting between central municipalities and surrounding municipalities and taking into account existing planning cooperation in the country's three geographic regions. They were defined around 1965. In 2005, a number of further municipalities were added to the defined areas. The word metropolitan describes

1500-469: A population exceeding one million as a metropolitan area as per the Code of Criminal Procedure, 1973 .

Jakarta , Surabaya , Bandung , Semarang , Medan , Makassar , Palembang are important metropolitan area in

1600-463: A rating of "D+" on its infrastructure. This aging infrastructure is a result of governmental neglect and inadequate funding. As the United States presumably looks to upgrade its existing infrastructure, sustainable measures could be a consideration of the design, build, and operation plans. Public infrastructure is that owned or available for use by the public (represented by the government ). It includes: A way to embody personal infrastructure

1700-403: A record high in 2010, partially due to governments' implemented economic stimulus measures with minimal consideration of the environmental consequences. The concern is whether this same pattern will repeat itself. The post-COVID-19 period could determine whether the world meets or misses the emissions goals of the 2015 Paris Agreement and limits global warming to 1.5 degrees C to 2 degrees C. As

1800-624: A region or district would be included with infrastructure, but the private irrigation systems on individual land parcels would be considered land improvements, not infrastructure. Service connections to municipal service and public utility networks would also be considered land improvements, not infrastructure. The term " public works " includes government-owned and operated infrastructure as well as public buildings, such as schools and courthouses. Public works generally refers to physical assets needed to deliver public services . Public services include both infrastructure and services generally provided by

1900-505: A result of the COVID-19 epidemic, a host of factors could jeopardize a low-carbon recovery plan: this includes reduced attention on the global political stage (2020 UN Climate Summit has been postponed to 2021), the relaxing of environmental regulations in pursuit of economic growth, decreased oil prices preventing low-carbon technologies from being competitive, and finally, stimulus programs that take away funds that could have been used to further

2000-402: A result, they soak 30% more water than conventional gardens. Bioswales are planted in paved areas like parking lots or sidewalks and are made to allow for overflow into the sewer system by trapping silt and other pollutants, which are normally left over from impermeable surfaces. Both rain gardens and bioswales mitigate flood impacts and prevent stormwater from polluting local waterways; increase

2100-514: A specified area by using property tax increases. In order to facilitate investment of the private sector in developing countries' infrastructure markets, it is necessary to design risk-allocation mechanisms more carefully, given the higher risks of their markets. The spending money that comes from the government is less than it used to be. From the 1930s to 2019, the United States went from spending 4.2% of GDP to 2.5% of GDP on infrastructure. These under investments have accrued, in fact, according to

2200-792: A specified standard of service by the continuing replacement and refurbishment of its components". Civil defense planners and developmental economists generally refer to both hard and soft infrastructure, including public services such as schools and hospitals , emergency services such as police and fire fighting, and basic services in the economic sector . The notion of infrastructure-based development combining long-term infrastructure investments by government agencies at central and regional levels with public private partnerships has proven popular among economists in Asia (notably Singapore and China), mainland Europe, and Latin America. Military infrastructure

2300-449: A total of US$ 24.9 billion. In irrigation , governments represent almost all spending. In transport and energy a majority of investment is government spending. In ICT and water supply and sanitation , the private sector represents the majority of capital expenditure. Overall, between them aid, the private sector, and non- OECD financiers exceed government spending. The private sector spending alone equals state capital expenditure, though

2400-523: Is a metropolitan area in the United Arab Emirates. It consists of the combined, greater urban areas of Dubai, Ajman, and Sharjah. The urban areas at the northeast end of Dubai flow into those of Sharjah, which in turn are contiguous with those of Ajman.

One benefit of green roofs

2600-438: Is defined as "those immobile, non-circulating capital goods that essentially contribute to the production of infrastructure goods and services needed to satisfy basic physical and social requirements of economic agents ". There are two distinct qualities of material infrastructures: 1) fulfillment of social needs and 2) mass production . The first characteristic deals with the basic needs of human life. The second characteristic

2700-466: Is generally only used as an administrative distinction in Turkey. The United Kingdom 's Office for National Statistics defines " travel to work areas " as areas where "at least 75% of an area's resident workforce work in the area and at least 75% of the people who work in the area also live in the area". The European Union 's ESPON group has compiled a separate list of metropolitan areas which covers

2800-527: Is generally paid for by metered user fees. Major investment projects are generally financed by the issuance of long-term bonds . Government-owned and operated infrastructure may be developed and operated in the private sector or in public-private partnerships , in addition to in the public sector . As of 2008 in the United States for example, public spending on infrastructure has varied between 2.3% and 3.6% of GDP since 1950. Many financial institutions invest in infrastructure. According to researchers at

The official definition of each area does not necessarily follow the actual extent of continuous urbanization. For example, the built-up area of Metro Manila has long spilled out of its officially defined borders into

3000-484: Is more beneficial in both an economic and environmental context, it represents the future of infrastructure. Especially with increasing pressure from climate change and diminishing natural resources, infrastructure not only needs to maintain economic development and job development, and a high quality of life for residents, but also protect the environment and its natural resources. Sustainable energy infrastructure includes types of renewable energy power plants as well as

3100-430: Is necessary to maintain growth and tackle poverty. The returns to investment in infrastructure are very significant, with on average thirty to forty percent returns for telecommunications ( ICT ) investments, over forty percent for electricity generation, and eighty percent for roads . The demand for infrastructure both by consumers and by companies is much higher than the amount invested. There are severe constraints on

The American Society of Civil Engineers publishes an "Infrastructure Report Card" which represents the organizations opinion on the condition of various infrastructure every 2–4 years. As of 2017 they grade 16 categories, namely aviation, bridges, dams, drinking water , energy, hazardous waste , inland waterways , levees , parks and recreation , ports , rail , roads , schools, solid waste , transit and wastewater . The United States has received

3300-572: Is not tabulated on the level of these Areas, but instead at the municipality or state level. In Canada, a census metropolitan area (CMA) or census agglomeration (CA) consists of one or more neighboring municipalities centered around a core population. A CMA requires a total population of at least 100,000, with 50,000 or more residing in the core, while a CA requires a core population of at least 10,000. Both are determined using data from Canada's Census of Population Program, and surrounding municipalities must demonstrate strong economic integration with

3400-409: Is that they reduce stormwater runoff because of its ability to store water in its growing media, reducing the runoff entering the sewer system and waterways, which also decreases the risk of combined sewer overflows. They reduce energy usage since the growing media provides additional insulation, reduces the amount of solar radiation on the roof's surface, and provides evaporative cooling from water in

3500-599: Is the buildings and permanent installations necessary for the support of military forces, whether they are stationed in bases, being deployed or engaged in operations. Examples include barracks, headquarters, airfields, communications facilities, stores of military equipment, port installations, and maintenance stations.

3800-812: Is the non-availability of infrastructure goods and services. Today, there are various materials that can be used to build infrastructure. The most prevalent ones are asphalt, concrete, steel, masonry, wood, polymers and composites. According to the business dictionary, economic infrastructure can be defined as "internal facilities of a country that make business activity possible, such as communication, transportation and distribution networks , financial institutions and related international markets, and energy supply systems". Economic infrastructure support productive activities and events. This includes roads, highways, bridges, airports, cycling infrastructure , water distribution networks, sewer systems , and irrigation plants. Social infrastructure can be broadly defined as

3900-746: Is the object of economic and legal policy. It compromises the growth and sets norms. It refers to the degree of fair treatment of equal economic data and determines the framework within which economic agents may formulate their own economic plans and carry them out in co-operation with others. Sustainable infrastructure refers to the processes of design and construction that take into consideration their environmental, economic, and social impact. Included in this section are several elements of sustainable schemes, including materials, water, energy, transportation, and waste management infrastructure. Although there are endless other factors of consideration, those will not be covered in this section. Material infrastructure

4000-744: Is to classify them as two distinct kinds: hard infrastructure and soft infrastructure . Hard infrastructure is the physical networks necessary for the functioning of a modern industrial society or industry . This includes roads, bridges, and railways. Soft infrastructure is all the institutions that maintain the economic , health , social , environmental , and cultural standards of a country. This includes educational programs , official statistics , parks and recreational facilities, law enforcement agencies, and emergency services . The word "infrastructure" has been used in French since 1875 and in English since 1887, originally meaning "installations that form

4100-504: Is to think of it in terms of human capital . Human capital is defined by the Encyclopædia Britannica as "intangible collective resources possessed by individuals and groups within a given population". The goal of personal infrastructure is to determine the quality of the economic agents' values. This results in three major tasks: the task of economic proxies in the economic process (teachers, unskilled and qualified labor, etc.);

These metropolitan areas are separated into three main geographical areas; Metro Manila (which

4400-743: The Overseas Development Institute , the lack of infrastructure in many developing countries represents one of the most significant limitations to economic growth and achievement of the Millennium Development Goals (MDGs) . Infrastructure investments and maintenance can be very expensive, especially in such areas as landlocked, rural and sparsely populated countries in Africa. It has been argued that infrastructure investments contributed to more than half of Africa's improved growth performance between 1990 and 2005, and increased investment

4500-790: The Rhine-Ruhr in Germany, and the Randstad in The Netherlands are other examples. In the United States , the concept of metropolitan statistical areas has gained prominence. The area of the Greater Washington metropolitan area is an example of statistically grouping independent cities and county areas from various states to form a larger city because of proximity, history and recent urban convergence. Metropolitan areas may themselves be part of

4600-448: The eurodistricts . As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas in the United States are delineated around the core of a core based statistical area which is defined as an urban area , (this is different than the urban core ) and consists of central and outlying counties, as the terms central city and suburb are no longer used by

4700-605: The Öresund has become more common, both through the Øresund Bridge and the HH Ferry route , at which car ferries departs every 12 minutes in summer (every 15 minutes in winter). Statistics Sweden , which sets the official definitions for all metropolitan areas in Sweden, has changed which municipalities are included in Greater Malmö over time. The most recent change to the definition came in 2006, when Eslöv , Höör , and Skurup Municipalities became part of Greater Malmö, bringing

4800-435: The 2017 ASCE Infrastructure Report Card, from 2016 to 2025, infrastructure will be underinvested by $ 2 trillion. Compared to the global GDP percentages, The United States is tied for second-to-last place, with an average percentage of 2.4%. This means that the government spends less money on repairing old infrastructure and or on infrastructure as a whole. In Sub-Saharan Africa , governments spend around US$ 9.4 billion out of

4900-760: The Bio Bio Region, with a population of about a million people living in it. Smaller "metropolitan" areas are known as conurbations. Conurbaciones tend to have a bit over 200.000 inhabitants to be considered as such. An example is the Conurbacion de Rancagua, which considers the area shared by the city of Rancagua, and the adjacent smaller towns of Machalí, Gultro and Graneros. Metropolitan areas are known as zonas metropolitanas in Mexico. The National Population Council (CONAPO) defines them as: As of 2018, there are 74 zonas metropolitanas in Mexico. 75.1 million people, 62.8% of

In India , a metropolitan city is defined as one with a population more than four million. In policing jurisdiction, state governments can declare any city or town with

5100-649: The French word structure . The army use of the term achieved currency in the United States after the formation of NATO in the 1940s, and by 1970 was adopted by urban planners in its modern civilian sense. A 1987 US National Research Council panel adopted the term " public works infrastructure", referring to: "... both specific functional modes – highways, streets, roads, and bridges; mass transit ; airports and airways; water supply and water resources ; wastewater management ; solid-waste treatment and disposal; electric power generation and transmission; telecommunications; and hazardous waste management – and

A rain garden is planted in a small depression or natural slope and includes native shrubs and flowers. They temporarily hold and absorb rain water and are effective in removing up to 90% of nutrients and chemicals and up to 80% of sediments from the runoff. As

5800-428: The appropriate built environments for these ecologically preferable modes of transportation. Cities will need to invest in public transportation networks, as well as bike path networks among other sustainable solutions that incentivize citizens to use these alternate transit options. Reducing the urban dependency on cars is a fundamental goal of developing sustainable transportation, and this cannot be accomplished without

5900-467: The basis for any operation or system". It is a loanword from French, where it was already used for establishing a roadbed of substrate material, required before railroad tracks or constructed pavement could be laid on top of it.

The metropolitan region is located in Västra Götaland County , except for the municipality of Kungsbacka , which is located to the south in Halland County . As of 2005, the municipalities of Alingsås and Lilla Edet were added to the region. The region is often used for statistical measures, and estimates in the 1960s predicted that the region would have about one million inhabitants in

6400-461: The combined system these modal elements comprise. A comprehension of infrastructure spans not only these public works facilities, but also the operating procedures, management practices, and development policies that interact together with societal demand and the physical world to facilitate the transport of people and goods, provision of water for drinking and a variety of other uses, safe disposal of society's waste products, provision of energy where it

6500-613: The construction and maintenance of facilities that support social services . Social infrastructures are created to increase social comfort and promote economic activity. These include schools, parks and playgrounds , structures for public safety , waste disposal plants, hospitals, and sports areas. Core assets provide essential services and have monopolistic characteristics. Investors seeking core infrastructure look for five different characteristics: income, low volatility of returns, diversification, inflation protection, and long-term liability matching. Core infrastructure incorporates all

6600-536: The contiguous built-up areas, which are not necessarily urban in character but are closely bound to the center by employment or other commerce. These outlying zones are sometimes known as a commuter belt and may extend well beyond the urban zone to other political entities. For example, East Hampton, New York , on Long Island is considered part of the New York metropolitan area . In 2020, the European Commission ,

7100-530: The economy. This has serious impacts on households, businesses, and federal, state and local governments. This is especially detrimental to infrastructure because it is so dependent on funding from government agencies – with state and local governments accounting for approximately 75% of spending on public infrastructure in the United States. Governments are facing enormous decreases in revenue, economic downturns, overworked health systems, and hesitant workforces, resulting in huge budget deficits across

7200-446: The established steady-state equilibrium of it. The materials should also be resilient, renewable, reusable, and recyclable. Today, concrete is one of the most common materials used in infrastructure. There is twice as much concrete used in construction than all other building materials combined. It is the backbone of industrialization, as it is used in bridges, piers, pipelines, pavements, and buildings. However, while they do serve as

A polycentric metropolitan area contains multiple urban agglomerations not connected by continuous development. In defining

7400-458: The following overlapping or related concepts. Land improvement and land development are general terms that in some contexts may include infrastructure, but in the context of a discussion of infrastructure would refer only to smaller-scale systems or works that are not included in infrastructure, because they are typically limited to a single parcel of land , and are owned and operated by the landowner. For example, an irrigation canal that serves

7500-428: The form of a large network; in other words, hard infrastructure . Efforts to devise more generic definitions of infrastructures have typically referred to the network aspects of most of the structures, and to the accumulated value of investments in the networks as assets. One such definition from 1998 defined infrastructure as the network of assets "where the system as a whole is intended to be maintained indefinitely at

7600-1131: The functional extent of a city as it contains the majority of the commuting population. GCCSAs replaced "Statistical Divisions" used until 2011. Other metropolitan areas in Australia include cross border cities or continuous built-up areas between two or more cities that are connected by an extensive public transport network that allows for commuting for work or services. In Bangladesh , the large population centres which have significant financial, political and administrative importance are considered to be as Metropolitan cities, which are governed by City Corporations . In total, there are 12 city corporations in Bangladesh. 4 of them ( Dhaka North City Corporation , Dhaka South City Corporation , Narayanganj City Corporation , Gazipur City Corporation ) are part of Dhaka Metropolitan Area . In China , there used to be no clear distinction between megalopolis ( 城市群 , lit. city cluster) and metropolitan area ( 都市圈 ) until National Development and Reform Commission issued Guidelines on

7700-473: The government. Infrastructure may be owned and managed by governments or by privately held companies, such as sole public utility or railway companies. Generally, most roads, major airports and other ports, water distribution systems, and sewage networks are publicly owned, whereas most energy and telecommunications networks are privately owned. Publicly owned infrastructure may be paid for from taxes, tolls, or metered user fees, whereas private infrastructure

7800-472: The holistic and effective management of water resources. Increasingly, policy makers and regulators are incorporating Nature-based solutions (NBS or NbS) into attempts to achieve sustainable water infrastructure. Sustainable waste management systems aim to minimize the amount of waste products produced by individuals and corporations. Commercial waste management plans have transitioned from simple waste removal plans into comprehensive plans focused on reducing

7900-480: The impact of raindrops on barren surfaces, minimize soil moisture through transpiration, and they help reduce stormwater runoff. Additionally, trees contribute to recharging local aquifers and improve the health of watershed systems. Trees also reduce energy usage by providing shade and releasing water into the atmosphere which cools the air and reduces the amount of heat absorbed by buildings. Finally, trees improve air quality by absorbing harmful air pollutants reducing

8000-451: The importance of personal infrastructure for an individual (short and long-term consumption of education); and the social relevance of personal infrastructure. Essentially, personal infrastructure maps the human impact on infrastructure as it is related to the economy, individual growth, and social impact. Institutional infrastructure branches from the term "economic constitution". According to Gianpiero Torrisi , institutional infrastructure

8100-416: The little parts of the engineering world that make life more convenient and efficient. They are needed to ensure successful usage and marketing of an already finished product, like in the case of road bridges . Other examples are lights on sidewalks, landscaping around buildings, and benches where pedestrians can rest. Engineers generally limit the term "infrastructure" to describe fixed assets that are in

8200-635: The main types of infrastructure, such as roads, highways, railways, public transportation , water, and gas supply. Basic infrastructure refers to main railways, roads, canals, harbors and docks, the electromagnetic telegraph, drainage, dikes, and land reclamation. It consist of the more well-known and common features of infrastructure that we come across in our daily lives (buildings, roads, docks). Complementary infrastructure refers to things like light railways, tramways, and gas/electricity/water supply. To complement something means to bring it to perfection or complete it. Complementary infrastructure deals with

8300-487: The majority is focused on ICT infrastructure investments. External financing increased in the 2000s (decade) and in Africa alone external infrastructure investments increased from US$ 7 billion in 2002 to US$ 27 billion in 2009. China, in particular, has emerged as an important investor. The 2020 COVID-19 pandemic has only exacerbated the underfunding of infrastructure globally that has been accumulating for decades. The pandemic has increased unemployment and has widely disrupted

8400-556: The market by prevailing non renewable energy sources. Sustainable water infrastructure is focused on a community's sufficient access to clean, safe drinking water. Water is a public good along with electricity, which means that sustainable water catchment and distribution systems must remain affordable to all members of a population. "Sustainable Water" may refer to a nation or community's ability to be self-sustainable, with enough water to meet multiple needs including agriculture, industry, sanitation, and drinking water. It can also refer to

8500-601: The means of exchange from the plant to the homes and businesses that use that energy. Renewable energy includes well researched and widely implemented methods such as wind, solar, and hydraulic power, as well as newer and less commonly used types of power creation such as fusion energy. Sustainable energy infrastructure must maintain a strong supply relative to demand, and must also maintain sufficiently low prices for consumers so as not to decrease demand. Any type of renewable energy infrastructure that fails to meet these consumption and price requirements will ultimately be forced out of

8600-627: The natural processes needed to manage water, reduce the effects of disasters such as flooding, and create healthier urban environments. In a more practical sense, it refers to a decentralized network of stormwater management practices, which includes green roofs, trees, bioretention and infiltration, and permeable pavement. Green infrastructure has become an increasingly popular strategy in recent years due to its effectiveness in providing ecological, economic, and social benefits – including positively impacting energy consumption, air quality, and carbon reduction and sequestration. A green roof

8700-574: The number of municipalities included from 9 to 12. Metropolitan area A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries , commercial areas , transport network , infrastructures and housing . A metropolitan area usually comprises multiple principal cities , jurisdictions and municipalities : neighborhoods , townships , boroughs , cities , towns , exurbs , suburbs , counties , districts and even states and nations in areas like

8800-492: The plants, which reduce the roof surface temperatures and heat influx. Green roofs also reduce atmospheric carbon dioxide since the vegetation sequesters carbon and, since they reduce energy usage and the urban heat island by reducing the roof temperature, they also lower carbon dioxide emissions from electricity generation. Tree planting provides a host of ecological, social, and economic benefits. Trees can intercept rain, support infiltration and water storage in soil, diminish

8900-615: The process of decarbonization . Research suggests that a recovery plan based on lower-carbon emissions could not only make significant emissions reductions needed to battle climate change, but also create more economic growth and jobs than a high-carbon recovery plan would. A study published in the Oxford Review of Economic Policy, more than 200 economists and economic officials reported that "green" economic-recovery initiatives performed at least as well as less "green" initiatives. There have also been calls for an independent body could provide

9000-472: The supply side of the provision of infrastructure in Asia. The infrastructure financing gap between what is invested in Asia-Pacific (around US$ 48 billion) and what is needed (US$ 228 billion) is around US$ 180 billion every year. In Latin America, three percent of GDP (around US$ 71 billion) would need to be invested in infrastructure in order to satisfy demand, yet in 2005, for example, only around two percent

9100-636: The surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure . Acknowledging this importance, the international community has created policy focused on sustainable infrastructure through the Sustainable Development Goals , especially Sustainable Development Goal 9 " Industry, Innovation and Infrastructure ". One way to describe different types of infrastructure

9200-471: The total amount of waste produced before removal. Sustainable waste management is beneficial environmentally, and can also cut costs for businesses that reduce their amount of disposed goods. Sustainable transportation includes a shift away from private, greenhouse gas emitting cars in favor of adopting methods of transportation that are either carbon neutral or reduce carbon emissions such as bikes or electric bus systems. Additionally, cities must invest in

9300-400: The urban center by commuting. The Australian Bureau of Statistics uses Greater Capital City Statistical Areas (GCCSAs), which are geographical areas designed to represent the functional extent of each of the eight state and territory capital cities. They were designed to reflect labor markets, using the 2011 Census "travel to work" data. Labor markets are sometimes used as proxy measures of

9400-442: The usable water supply by reducing the amount of water needed for outdoor irrigation; improve air quality by minimizing the amount of water going into treatment facilities, which also reduces energy usage and, as a result, reduces air pollution since less greenhouse gases are emitted. Smart cities use innovative methods of design and implementation in various sectors of infrastructure and planning to create communities that operate at

9500-786: The wider transnational Öresund Region . Besides Malmö, large towns in Greater Malmö includes Lund and Trelleborg , the former of which was the seat of the historical Catholic Archdiocese of Lund . Since the 1970s, improvements in highways and the regional and InterRegio train networks means the commuting area has grown to include Ystad , Skurup , Sjöbo , Eslöv , Höör , Landskrona and Helsingborg , though only some of these are included in official definitions of Greater Malmö. It's not uncommon to live in Malmö and work either in Ystad or Helsingborg, or vice versa, but these towns have kept their mental allegiance with older divisions of Scania. Commuting across

9600-460: The world's industrial water usage is from producing concrete. Even transporting the raw materials to concrete production sites adds to airborne pollution. Furthermore, the production sites and the infrastructures themselves all strip away agricultural land that could have been fertile soil or habitats vital to the ecosystem. Green infrastructure is a type of sustainable infrastructure. Green infrastructure uses plant or soil systems to restore some of

9700-463: The year 2000. The region is the second largest metropolitan area in Sweden after Metropolitan Stockholm . km Population per km Greater Malmö ( Stormalmö ), also known as Metropolitan Malmö is the metropolitan area of Malmö in Sweden. The area is located in Southwestern Scania ( Sydvästra Skåne ), which is often considered synonymous with Greater Malmö, and it is part of

9800-543: Was defined differently than the AAV, has now been discarded by INSEE and replaced with the AAV in order to facilitate international comparisons. Metropolitan regions in Germany by definition, are the eleven urban areas that are the most densely populated areas in the Federal Republic of Germany . They comprise the major German cities and their surrounding catchment areas and form the political, commercial and cultural centers of

9900-768: Was invested leaving a financing gap of approximately US$ 24 billion. In Africa, in order to reach the seven percent annual growth calculated to be required to meet the MDGs by 2015 would require infrastructure investments of about fifteen percent of GDP, or around US$ 93 billion a year. In fragile states , over thirty-seven percent of GDP would be required. The source of financing for infrastructure varies significantly across sectors. Some sectors are dominated by government spending , others by overseas development aid (ODA) , and yet others by private investors. In California, infrastructure financing districts are established by local governments to pay for physical facilities and services within

10000-574: Was over 9.6 million as of the 2011 South Africa Census, in contrast to its urban area, which consisted of approximately 7.9 million inhabitants as of 2011. Conversely, metropolitan municipalities in South Africa are defined as commonly governed areas of a metropolitan area. The largest such metropolitan municipal government entity in South Africa is the City of Johannesburg Metropolitan Municipality , which presided over nearly 5 million people as of 2016. However,
