110-479: This is the second-largest region in terms of territory. It has a total area of 2,555 km, with a central position and good traffic connections in all directions, and the country's capital is located in it. The area is the most densely populated statistical region in Slovenia, with the largest number of inhabitants. The population in 2020 was 570,773. It had the highest proportion of people between ages 25 and 64 with

220-417: A limits discourse is an economically reformist, yet politically conservative approach to sustainability. Fourth, radical sustainability is a transformative approach seeking to break with existing global economic and political structures. Sustainable development, like sustainability , is regarded to have three dimensions : the environment, economy and society . The idea is that a good balance between

330-549: A post-secondary education. The Central Slovenia Statistical Region includes 9 cities and towns , the largest of which is Ljubljana . The Central Slovenia Statistical Region comprises the following 25 municipalities : The Municipality of Litija was part of the region until January 2015; it became part of the Central Sava Statistical Region in 2015. As the economically most developed region, in 2012 it generated 27 times more gross domestic product than

440-411: A sustainable yield (the rate of harvest should not exceed the rate of regeneration); for non-renewable resources there should be equivalent development of renewable substitutes; waste generation should not exceed the assimilative capacity of the environment. In 2019, a summary for policymakers of the largest, most comprehensive study to date of biodiversity and ecosystem services was published by

550-541: A "lack of concrete understanding of what "sustainability policies" might entail in practice". A study concluded in 2007 that knowledge, manufactured and human capital (health and education) has not compensated for the degradation of natural capital in many parts of the world. It has been suggested that intergenerational equity can be incorporated into a sustainable development and decision making, as has become common in economic valuations of climate economics . The World Business Council for Sustainable Development published

660-543: A Vision 2050 document in 2021 to show "How business can lead the transformations the world needs". The vision states that "we envision a world in which 9+billion people can live well, within planetary boundaries , by 2050." This report was highlighted by The Guardian as "the largest concerted corporate sustainability action plan to date – include reversing the damage done to ecosystems, addressing rising greenhouse gas emissions and ensuring societies move to sustainable agriculture." There are many reasons why sustainability

770-573: A central area containing buildings with special economic, political, and religious significance. Archaeologists refer to this area by the Greek term temenos or if fortified as a citadel . These spaces historically reflect and amplify the city's centrality and importance to its wider sphere of influence . Today cities have a city center or downtown , sometimes coincident with a central business district . Cities typically have public spaces where anyone can go. These include privately owned spaces open to

880-665: A central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there and can be used in a general sense to mean urban rather than rural territory . National censuses use a variety of definitions – invoking factors such as population , population density , number of dwellings , economic function, and infrastructure – to classify populations as urban. Typical working definitions for small-city populations start at around 100,000 people. Common population definitions for an urban area (city or town) range between 1,500 and 50,000 people, with most U.S. states using

990-461: A central point. This form could evolve from successive growth over a long time, with concentric traces of town walls and citadels marking older city boundaries. In more recent history, such forms were supplemented by ring roads moving traffic around the outskirts of a town. Dutch cities such as Amsterdam and Haarlem are structured as a central square surrounded by concentric canals marking every expansion. In cities such as Moscow , this pattern

1100-539: A combination of these. Societies that live in cities are often called civilizations . The degree of urbanization is a modern metric to help define what comprises a city: "a population of at least 50,000 inhabitants in contiguous dense grid cells (>1,500 inhabitants per square kilometer)". This metric was "devised over years by the European Commission , OECD , World Bank and others, and endorsed in March [2021] by

1210-604: A continuous urban landscape called urban agglomeration , conurbation , or megalopolis (exemplified by the BosWash corridor of the Northeastern United States .) The emergence of cities from proto-urban settlements , such as Çatalhöyük , is a non-linear development that demonstrates the varied experiences of early urbanization . The cities of Jericho , Aleppo , Byblos , Faiyum , Yerevan , Athens , Matera , Damascus , and Argos are among those laying claim to

1320-430: A distinctive elite social class, but it should indeed be considered a city based on a functional redefinition of urban development. In particular, Jenné-Jeno featured settlement mounds arranged according to a horizontal, rather than vertical, power hierarchy, and served as a center of specialized production and exhibited functional interdependence with the surrounding hinterland. More recently, scholars have concluded that

1430-621: A global priority and introduced the term "sustainable development". Two years later, the United Nations World Charter for Nature raised five principles of conservation by which human conduct affecting nature is to be guided and judged. Since the Brundtland Report , the concept of sustainable development has developed beyond the initial intergenerational framework to focus more on the goal of "socially inclusive and environmentally sustainable economic growth ". In 1992,

1540-466: A grid plan with specialized districts used across the Hellenistic Mediterranean . The urban-type settlement extends far beyond the traditional boundaries of the city proper in a form of development sometimes described critically as urban sprawl . Decentralization and dispersal of city functions (commercial, industrial, residential, cultural, political) has transformed the very meaning of

1650-405: A growth in the gross domestic product. This model of unlimited personal and GDP growth may be over. Sustainable development may involve improvements in the quality of life for many but may necessitate a decrease in resource consumption . "Growth" generally ignores the direct effect that the environment may have on social welfare, whereas "development" takes it into account. As early as the 1970s,

1760-434: A healthy environment. No new ethic is required. This so-called weak version of sustainability is popular among governments, and businesses, but profoundly wrong and not even weak , as there is no alternative to preserving the earth's ecological integrity." Scholars have stated that sustainable development is open-ended, much critiqued as ambiguous, incoherent, and therefore easily appropriated. Sustainable development

1870-507: A key role in both the economy and government. Late antique cities in the East were also undergoing intense transformations, with increased political participation of the crowds and demographical fluctuations. Christian communities and their doctrinal differences increasingly shaped the urban fabric. The locus of power shifted to Constantinople and to the ascendant Islamic civilization with its major cities Baghdad , Cairo , and Córdoba . From

1980-520: A minimum between 1,500 and 5,000 inhabitants. Some jurisdictions set no such minima. In the United Kingdom , city status is awarded by the Crown and then remains permanent. (Historically, the qualifying factor was the presence of a cathedral , resulting in some very small cities such as Wells , with a population of 12,000 as of 2018 , and St Davids , with a population of 1,841 as of 2011 .) According to

2090-553: A more sustainable world), while sustainable development refers to the many processes and pathways to achieve it." The Rio Process that began at the 1992 Earth Summit in Rio de Janeiro has placed the concept of sustainable development on the international agenda. Sustainable development is the foundational concept of the Sustainable Development Goals (SDGs). These global goals for the year 2030 were adopted in 2015 by

2200-407: A national duty of every landowner, in order to stop the destructive over- exploitation of natural resources ." In 1713, Hans Carl von Carlowitz , a senior mining administrator in the service of Elector Frederick Augustus I of Saxony published Sylvicultura economics , a 400-page work on forestry. Building upon the ideas of Evelyn and French minister Jean-Baptiste Colbert , von Carlowitz developed

2310-688: A privileged elite among towns having won self-governance from their local lord or having been granted self-governance by the emperor and being placed under his immediate protection. By 1480, these cities, as far as still part of the empire, became part of the Imperial Estates governing the empire with the emperor through the Imperial Diet . By the 13th and 14th centuries, some cities become powerful states, taking surrounding areas under their control or establishing extensive maritime empires. In Italy, medieval communes developed into city-states including

2420-495: A rule cannot produce their own food and therefore must develop some relationship with a hinterland that sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would, in theory, favor the creation of marketplaces in optimal mutually reachable locations. The vast majority of cities have

2530-549: A super-wealthy elite living in gated communities and large masses of people living in substandard housing with inadequate infrastructure and otherwise poor conditions. Cities around the world have expanded physically as they grow in population, with increases in their surface extent, with the creation of high-rise buildings for residential and commercial use, and with development underground. Urbanization can create rapid demand for water resources management , as formerly good sources of freshwater become overused and polluted, and

2640-423: A temple. A minority viewpoint considers that cities may have arisen without agriculture, due to alternative means of subsistence (fishing), to use as communal seasonal shelters, to their value as bases for defensive and offensive military organization, or to their inherent economic function. Cities played a crucial role in the establishment of political power over an area, and ancient leaders such as Alexander

2750-567: A workers' town associated with the pyramid of Senusret II , and the religious city Amarna built by Akhenaten and abandoned. These sites appear planned in a highly regimented and stratified fashion, with a minimalistic grid of rooms for the workers and increasingly more elaborate housing available for higher classes. In Mesopotamia, the civilization of Sumer , followed by Assyria and Babylon , gave rise to numerous cities, governed by kings and fostered multiple languages written in cuneiform . The Phoenician trading empire, flourishing around

2860-471: A world of intensifying globalization , all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues , such as sustainable development , climate change , and global health . Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11 . Due to

2970-487: Is a conservative approach on both economic and political terms. Second, progressive sustainability is an economically conservative, yet politically reformist approach. Under this framing, sustainable development is still centered on economic growth, which is deemed compatible with environmental sustainability. However, human well-being and development can only be achieved through a redistribution of power to even out inequalities between developed and developing countries. Third,

3080-478: Is a fundamental prerequisite for achieving sustainable development. The Rio Protocol was a huge leap forward: for the first time, the world agreed on a sustainability agenda. In fact, a global consensus was facilitated by neglecting concrete goals and operational details. The most comprehensive global governance framework for sustainable development is the 2030 Agenda for Sustainable Development with its 17 Sustainable Development Goals (SDGs). This agenda

3190-527: Is a structural imperative for growth in competitive market economies. This inhibits necessary societal change. Furthermore, there are several barriers related to the difficulties of implementing sustainability policies. There are trade-offs between the goals of environmental policies and economic development. Environmental goals include nature conservation. Development may focus on poverty reduction. There are also trade-offs between short-term profit and long-term viability. Political pressures generally favor

3300-475: Is open-ended, much critiqued as ambiguous, incoherent, and therefore easily appropriated. In 1987, the United Nations World Commission on Environment and Development released the report Our Common Future , commonly called the Brundtland Report . The report included a definition of "sustainable development" which is now widely used: Sustainable development is a development that meets

3410-532: Is possible that we can find ways to replace some natural resources, it is much less likely that they will ever be able to replace ecosystem services , such as the protection provided by the ozone layer, or the climate stabilizing function of the Amazonian forest. The concept of sustainable development has been criticized from different angles. While some see it as paradoxical (or an oxymoron ) and regard development as inherently unsustainable, others are disappointed in

3520-458: Is so difficult to achieve. These reasons have the name sustainability barriers . Before addressing these barriers it is important to analyze and understand them. Some barriers arise from nature and its complexity ("everything is related"). Others arise from the human condition. One example is the value-action gap . This reflects the fact that people often do not act according to their convictions. Experts describe these barriers as intrinsic to

3630-508: Is still clearly visible. A system of rectilinear city streets and land plots, known as the grid plan , has been used for millennia in Asia, Europe, and the Americas. The Indus Valley Civilization built Mohenjo-Daro , Harappa , and other cities on a grid pattern, using ancient principles described by Kautilya , and aligned with the compass points . The ancient Greek city of Priene exemplifies

3740-540: Is the foundational concept of the Sustainable Development Goals (SDGs). Policies to achieve the SDGs are meant to cohere around this concept. The 2030 Agenda for Sustainable Development , adopted by all United Nations (UN) members in 2015, created 17 world Sustainable Development Goals (SDGs). The aim of these global goals is " peace and prosperity for people and the planet" – while tackling climate change and working to preserve oceans and forests. The SDGs highlight

Batam , Indonesia , Mogadishu , Somalia , Xiamen , China , and Niamey , Niger , are considered among the world's fastest-growing cities, with annual growth rates of 5–8%. In general, the more developed countries of

3960-515: Is used up faster than it can be replenished. Sustainability requires that human activity only uses nature's resources at a rate at which they can be replenished naturally. The concept of sustainable development is intertwined with the concept of carrying capacity . Theoretically, the long-term result of environmental degradation is the inability to sustain human life. Important operational principles of sustainable development were published by Herman Daly in 1990: renewable resources should provide

4070-513: The Central Sava Statistical Region , or more than a third of the national GDP. In 2012 the region recorded 98 new companies per 10,000 population (the highest number of new companies was recorded in the Coastal–Karst Statistical Region ; namely, 113 per 10,000 population). At the same time, this region had one of the highest five-year survival rates of new companies (55%). According to the labour migration index (126.0), this region

4180-603: The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services . It recommended that human civilization will need a transformative change, including sustainable agriculture , reductions in consumption and waste, fishing quotas and collaborative water management. Environmental problems associated with industrial agriculture and agribusiness are now being addressed through approaches such as sustainable agriculture , organic farming and more sustainable business practices . At

Their power was later challenged and eclipsed by the Dutch commercial cities of Ghent , Ypres , and Amsterdam . Similar phenomena existed elsewhere, as in the case of Sakai , which enjoyed considerable autonomy in late medieval Japan. In

The action plan Agenda 21 for sustainable development identified information, integration, and participation as key building blocks to help countries achieve development that recognizes these interdependent pillars. Furthermore, Agenda 21 emphasizes that broad public participation in decision-making

4510-931: The United Nations ... largely for the purpose of international statistical comparison". The word city and the related civilization come from the Latin root civitas , originally meaning 'citizenship' or 'community member' and eventually coming to correspond with urbs , meaning 'city' in a more physical sense. The Roman civitas was closely linked with the Greek polis —another common root appearing in English words such as metropolis . In toponymic terminology, names of individual cities and towns are called astionyms (from Ancient Greek ἄστυ 'city or town' and ὄνομα 'name'). Urban geography deals both with cities in their larger context and with their internal structure. Cities are estimated to cover about 3% of

There are some problems with the concept of sustainable development. Some scholars say it is an oxymoron because according to them, development is inherently unsustainable. Other commentators are disappointed in the lack of progress that has been achieved so far. Scholars have stated that sustainable development

4730-501: The Uruk period . In the fourth and third millennium BC , complex civilizations flourished in the river valleys of Mesopotamia , India , China , and Egypt . Excavations in these areas have found the ruins of cities geared variously towards trade, politics, or religion. Some had large, dense populations , but others carried out urban activities in the realms of politics or religion without having large associated populations. Among

4840-716: The civilization of Djenne-Djenno was likely established by the Mande progenitors of the Bozo people . Their habitation of the site spanned the period from 3rd century BCE to 13th century CE. Archaeological evidence from Jenné-Jeno, specifically the presence of non-West African glass beads dated from the third century BCE to the fourth century CE, indicates that pre-Arabic trade contacts probably existed between Jenné-Jeno and North Africa. Additionally, other early urban centers in West Africa, dated to around 500 CE, include Awdaghust , Kumbi Saleh ,

4950-568: The commune ( in France and Chile ; or comune in Italy). Sustainable development Sustainable development is an approach to growth and human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. The aim is to have a society where living conditions and resources meet human needs without undermining planetary integrity . Sustainable development aims to balance

5060-427: The government workers . (This arrangement contrasts with the more typically horizontal relationships in a tribe or village accomplishing common goals through informal agreements between neighbors, or the leadership of a chief.) The governments may be based on heredity, religion, military power, work systems such as canal-building, food distribution, land-ownership, agriculture, commerce, manufacturing, finance, or

5170-530: The knowledge economy . A new smart city paradigm, supported by institutions such as the RAND Corporation and IBM , is bringing computerized surveillance , data analysis, and governance to bear on cities and city dwellers. Some companies are building brand-new master-planned cities from scratch on greenfield sites. Urbanization is the process of migration from rural to urban areas, driven by various political, economic, and cultural factors. Until

Under the Great Leap Forward and subsequent five-year plans continuing today, China has undergone concomitant urbanization and industrialization and become the world's leading manufacturer . Amidst these economic changes, high technology and instantaneous telecommunication enable select cities to become centers of

5390-535: The " Global North " remain more urbanized than the less developed countries of the " Global South "—but the difference continues to shrink because urbanization is happening faster in the latter group. Asia is home to by far the greatest absolute number of city-dwellers: over two billion and counting. The UN predicts an additional 2.5 billion city dwellers (and 300 million fewer country dwellers) worldwide by 2050, with 90% of urban population expansion occurring in Asia and Africa. Megacities , cities with populations in

5500-539: The "functional definition", a city is not distinguished by size alone, but also by the role it plays within a larger political context. Cities serve as administrative, commercial, religious, and cultural hubs for their larger surrounding areas. The presence of a literate elite is often associated with cities because of the cultural diversities present in a city. A typical city has professional administrators , regulations, and some form of taxation (food and other necessities or means to trade for them) to support

In the West, nation-states became the dominant unit of political organization following the Peace of Westphalia in the seventeenth century. Western Europe's larger capitals (London and Paris) benefited from the growth of commerce following

5720-420: The 18th century, an equilibrium existed between the rural agricultural population and towns featuring markets and small-scale manufacturing. With the agricultural and industrial revolutions urban population began its unprecedented growth, both through migration and demographic expansion . In England , the proportion of the population living in cities jumped from 17% in 1801 to 72% in 1891. In 1900, 15% of

5830-698: The 30th and 18th centuries BC. Mesoamerica saw the rise of early urbanism in several cultural regions, beginning with the Olmec and spreading to the Preclassic Maya , the Zapotec of Oaxaca, and Teotihuacan in central Mexico. Later cultures such as the Aztec , Andean civilizations , Mayan , Mississippians , and Pueblo peoples drew on these earlier urban traditions. Many of their ancient cities continue to be inhabited, including major metropolitan cities such as Mexico City , in

5940-722: The 9th through the end of the 12th century, Constantinople , the capital of the Eastern Roman Empire , was the largest and wealthiest city in Europe, with a population approaching 1 million. The Ottoman Empire gradually gained control over many cities in the Mediterranean area, including Constantinople in 1453 . In the Holy Roman Empire , beginning in the 12th century, free imperial cities such as Nuremberg , Strasbourg , Frankfurt , Basel , Zürich , and Nijmegen became

6050-552: The Andes, the first urban centers developed in the Norte Chico civilization , Chavin and Moche cultures, followed by major cities in the Huari , Chimu , and Inca cultures. The Norte Chico civilization included as many as 30 major population centers in what is now the Norte Chico region of north-central coastal Peru . It is the oldest known civilization in the Americas, flourishing between

6160-519: The Great founded and created them with zeal. Jericho and Çatalhöyük , dated to the eighth millennium BC , are among the earliest proto-cities known to archaeologists. However, the Mesopotamian city of Uruk from the mid-fourth millennium BC (ancient Iraq) is considered by most archaeologists to be the first true city, innovating many characteristics for cities to follow, with its name attributed to

6270-530: The ancient capital of Ghana, and Maranda , a center located on a trade route between Egypt and Gao. The dissolution of the Roman Empire in the West was connected with profound changes in urban fabric of western Europe. In places where Roman administration quickly weakened urbanism went through a profound crisis, even if it continued to remain an important symbolic factor. In regions like Italy or Spain cities diminished in size but nevertheless continued to play

6380-460: The athletic, artistic, spiritual, and political life of the polis. Rome was the first city that surpassed one million inhabitants. Under the authority of its empire , Rome transformed and founded many cities ( Colonia ), and with them brought its principles of urban architecture, design, and society. In the ancient Americas , early urban traditions developed in the Andes and Mesoamerica . In

6490-407: The benefit of mitigating the urban heat island effect, especially in cities that are in warmer climates. These spaces prevent carbon imbalances, extreme habitat losses, electricity and water consumption, and human health risks. The urban structure generally follows one or more basic patterns: geomorphic, radial, concentric, rectilinear, and curvilinear. The physical environment generally constrains

6600-464: The capacities to measure progress towards sustainable development; promote equity within and between generations; adapt to shocks and surprises; transform the system onto more sustainable development pathways; link knowledge with action for sustainability; and to devise governance arrangements that allow people to work together. During the MDG era (year 2000 to 2015), the key objective of sustainable development

6710-492: The concept of managing forests for sustained yield . His work influenced others, including Alexander von Humboldt and Georg Ludwig Hartig , eventually leading to the development of the science of forestry. This, in turn, influenced people like Gifford Pinchot , the first head of the US Forest Service , whose approach to forest management was driven by the idea of wise use of resources, and Aldo Leopold whose land ethic

6820-407: The concept of sustainability was used to describe an economy "in equilibrium with basic ecological support systems". Scientists in many fields have highlighted The Limits to Growth , and economists have presented alternatives, for example a ' steady-state economy ', to address concerns over the impacts of expanding human development on the planet. In 1987, the economist Edward Barbier published

6930-450: The concept of sustainability. Other barriers are extrinsic to the concept of sustainability. This means it is possible to overcome them. One way would be to put a price tag on the consumption of public goods. Some extrinsic barriers relate to the nature of dominant institutional frameworks. Examples would be where market mechanisms fail for public goods . Existing societies, economies, and cultures encourage increased consumption. There

7040-428: The concept of sustainable development has led to a diversity of discourses that legitimize competing sociopolitical projects. Global environmental governance scholars have identified a comprehensive set of discourses within the public space that mostly convey four sustainability frames: mainstream sustainability, progressive sustainability, a limits discourse, and radical sustainability. First, mainstream sustainability

7150-828: The connections between the environmental, social and economic aspects of sustainable development. Sustainability is at the center of the SDGs, as the term sustainable development implies. The short titles of the 17 SDGs are: No poverty ( SDG 1 ), Zero hunger ( SDG 2 ), Good health and well-being ( SDG 3 ), Quality education ( SDG 4 ), Gender equality ( SDG 5 ), Clean water and sanitation ( SDG 6 ), Affordable and clean energy ( SDG 7 ), Decent work and economic growth ( SDG 8 ), Industry, innovation and infrastructure ( SDG 9 ), Reduced inequalities ( SDG 10 ), Sustainable cities and communities ( SDG 11 ), Responsible consumption and production ( SDG 12 ), Climate action ( SDG 13 ), Life below water ( SDG 14 ), Life on land ( SDG 15 ), Peace, justice, and strong institutions ( SDG 16 ), and Partnerships for

7260-523: The dominant market-based socio-economic-political organisation. Attempts towards universal sustainable development need to account for the extremely varied challenges, circumstances, and choices that shape prospects and prosperity for all, everywhere. The discourse of sustainable development is highly influential in global and national governance frameworks , though its meaning and operationalization are context-dependent and have evolved over time. The evolution of this discourse can for example be seen in

7370-536: The early Old World cities, Mohenjo-daro of the Indus Valley civilization in present-day Pakistan , existing from about 2600 BC, was one of the largest, with a population of 50,000 or more and a sophisticated sanitation system . China's planned cities were constructed according to sacred principles to act as celestial microcosms . The Ancient Egyptian cities known physically by archaeologists are not extensive. They include (known by their Arab names) El Lahun ,

7480-671: The efficiency of transportation and the smaller land consumption , dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant negative consequences, such as forming urban heat islands , concentrating pollution , and stressing water supplies and other resources. A city can be distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status , which may be conferred by

7590-479: The emergence of an Atlantic trade. However, most towns remained small. During the Spanish colonization of the Americas, the old Roman city concept was extensively used. Cities were founded in the middle of the newly conquered territories and were bound to several laws regarding administration, finances, and urbanism. The growth of the modern industry from the late 18th century onward led to massive urbanization and

7700-500: The exhaustion of earth's finite stock; this perspective renders the Industrial Revolution as a whole unsustainable. The sustainable development debate is based on the assumption that societies need to manage three types of capital (economic, social, and natural), which may be non-substitutable and whose consumption might be irreversible. Natural capital can not necessarily be substituted by economic capital. While it

7810-791: The first millennium AD, the Khmer capital of Angkor in Cambodia grew into the most extensive preindustrial settlement in the world by area, covering over 1,000 km and possibly supporting up to one million people. West Africa already had cities before the Common Era , but the consolidation of Trans-Saharan trade in the Middle Ages multiplied the number of cities in the region, as well as making some of them very populous, notably Gao (72,000 inhabitants in 800 AD), Oyo-Ile (50,000 inhabitants in 1400 AD, and may have reached up to 140,000 inhabitants in

7920-440: The form in which a city is built. If located on a mountainside, urban structures may rely on terraces and winding roads. It may be adapted to its means of subsistence (e.g. agriculture or fishing). And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphic" features, cities can develop internal patterns, due to natural growth or to city planning . In a radial structure, main roads converge on

8030-496: The goals ( SDG 17 ). Education for sustainable development (ESD) is a term officially used by the United Nations . It is defined as education practices that encourage changes in knowledge, skills, values, and attitudes to enable a more sustainable and just society for humanity. ESD aims to empower and equip current and future generations to meet their needs using a balanced and integrated approach to sustainable development's economic, social, and environmental dimensions. Agenda 21

8140-497: The lack of progress that has been achieved so far. Part of the problem is that "development" itself is not consistently defined. The vagueness of the Brundtland definition of sustainable development has been criticized as follows: The definition has "opened up the possibility of downplaying sustainability. Hence, governments spread the message that we can have it all at the same time, i.e. economic growth, prospering societies and

8250-468: The land surface of the Earth. Town siting has varied through history according to natural, technological, economic, and military contexts. Access to water has long been a major factor in city placement and growth, and despite exceptions enabled by the advent of rail transport in the nineteenth century, through the present most of the world's urban population lives near the coast or on a river. Urban areas as

8360-400: The linear path of materials (extraction, use, disposal in landfill) to a circular material flow that reuses materials as much as possible, much like the cycling and reuse of waste in nature. This way of thinking is expressed in the concept of circular economy , which employs reuse , sharing , repair, refurbishment, remanufacturing and recycling to create a closed-loop system, minimizing

8470-452: The local level there are various movements working towards sustainable food systems which may include less meat consumption, local food production, slow food , sustainable gardening , and organic gardening . The environmental effects of different dietary patterns depend on many factors, including the proportion of animal and plant foods consumed and the method of food production. As global population and affluence have increased, so has

8580-427: The long-acknowledged sustainability concept of preserving forests for future wood production can be directly transferred to the broader importance of preserving environmental resources to sustain the world for future generations. That same year, the interrelationship of environment and development was formally demonstrated in a systems dynamic simulation model reported in the classic report on Limits to Growth . This

8690-475: The longest continual inhabitation . Cities, characterized by population density , symbolic function, and urban planning , have existed for thousands of years. In the conventional view, civilization and the city were both followed by the development of agriculture , which enabled the production of surplus food and thus a social division of labor (with concomitant social stratification ) and trade . Early cities often featured granaries , sometimes within

8800-492: The multi-millions, have proliferated into the dozens, arising especially in Asia, Africa, and Latin America. Economic globalization fuels the growth of these cities, as new torrents of foreign capital arrange for rapid industrialization, as well as the relocation of major businesses from Europe and North America, attracting immigrants from near and far. A deep gulf divides the rich and poor in these cities, which usually contain

8910-466: The need for the economic system to fit itself to the ecological system with its limited pools of resources. Another milestone was the 1968 article by Garrett Hardin that popularized the term " tragedy of the commons ". The direct linking of sustainability and development in a contemporary sense can be traced to the early 1970s. "Strategy of Progress", a 1972 book (in German) by Ernst Basler, explained how

9020-405: The needs of the economy , environment , and social well-being . The Brundtland Report in 1987 helped to make the concept of sustainable development better known. Sustainable development overlaps with the idea of sustainability which is a normative concept . UNESCO formulated a distinction between the two concepts as follows: " Sustainability is often thought of as a long-term goal (i.e.

9130-420: The needs of the present without compromising the ability of future generations to meet their own needs. It contains two key concepts within it: Sustainable development thus tries to find a balance between economic development , environmental protection , and social well-being . However, scholars have pointed out that there are manifold understandings of sustainable development. Also there are incoherencies in

9240-573: The process, such as improving the efficiency of goods and service distribution. Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization , more than half of the world population now lives in cities, which has had profound consequences for global sustainability . Present-day cities usually form the core of larger metropolitan areas and urban areas —creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in

9350-500: The public as well as forms of public land such as public domain and the commons . Western philosophy since the time of the Greek agora has considered physical public space as the substrate of the symbolic public sphere . Public art adorns (or disfigures) public spaces. Parks and other natural sites within cities provide residents with relief from the hardness and regularity of typical built environments . Urban green spaces are another component of public space that provides

9460-604: The publication of the influential book, A Blueprint for Survival . In 1975, an MIT research group prepared ten days of hearings on "Growth and Its Implication for the Future" for the US Congress , the first hearings ever held on sustainable development. In 1980, the International Union for Conservation of Nature published a world conservation strategy that included one of the first references to sustainable development as

9570-866: The rise of new great cities, first in Europe and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. England led the way as London became the capital of a world empire and cities across the country grew in locations strategic for manufacturing . In the United States from 1860 to 1910, the introduction of railroads reduced transportation costs, and large manufacturing centers began to emerge, fueling migration from rural to city areas. Some industrialized cities were confronted with health challenges associated with overcrowding , occupational hazards of industry, contaminated water and air, poor sanitation , and communicable diseases such as typhoid and cholera . Factories and slums emerged as regular features of

9680-680: The same location as Tenochtitlan ; while ancient continuously inhabited Pueblos are near modern urban areas in New Mexico , such as Acoma Pueblo near the Albuquerque metropolitan area and Taos Pueblo near Taos ; while others like Lima are located nearby ancient Peruvian sites such as Pachacamac . From 1600 BC, Dhar Tichitt , in the south of present-day Mauritania , presented characteristics suggestive of an incipient form of urbanism. The second place to show urban characteristics in West Africa

9790-437: The same thing in this context. The three dimensions paradigm has few theoretical foundations. Countries could develop systems for monitoring and evaluation of progress towards achieving sustainable development by adopting indicators that measure changes across economic, social and environmental dimensions. Six interdependent capacities are deemed to be necessary for the successful pursuit of sustainable development. These are

9900-437: The short term over the long term. So they form a barrier to actions oriented toward improving sustainability. The concept of sustainable development has been and still is, subject to criticism, including the question of what is to be sustained in sustainable development. It has been argued that there is no such thing as sustainable use of a non-renewable resource , since any positive rate of exploitation will eventually lead to

10010-400: The study The Concept of Sustainable Economic Development , where he recognized that goals of environmental conservation and economic development are not conflicting and can be reinforcing each other. A World Bank study from 1999 concluded that based on the theory of genuine savings (defined as "traditional net savings less the value of resource depletion and environmental degradation plus

10120-486: The term and has challenged geographers seeking to classify territories according to an urban-rural binary. Metropolitan areas include suburbs and exurbs organized around the needs of commuters , and sometimes edge cities characterized by a degree of economic and political independence. (In the US these are grouped into metropolitan statistical areas for purposes of demography and marketing .) Some cities are now part of

10230-610: The term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing , transportation , sanitation , utilities , land use , production of goods , and communication . Their density facilitates interaction between people, government organizations , and businesses , sometimes benefiting different parties in

10340-438: The three dimensions should be achieved. Instead of calling them dimensions , other terms commonly used are pillars , domains , aspects , spheres . Scholars usually distinguish three different areas of sustainability. These are the environmental, the social, and the economic. Several terms are in use for this concept. Authors may speak of three pillars, dimensions, components, aspects, perspectives, factors, or goals. All mean

10450-411: The total number of tourists in Slovenia, most being visitors from abroad who visit Ljubljana (90.7%). 46°03′00″N 14°31′00″E  /  46.05000°N 14.51667°E  / 46.05000; 14.51667 City A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where

10560-623: The transition from the Millennium Development Goals (MDGs, years 2000 to 2015) to the Sustainable Development Goals (SDGs, years 2015 to 2030). Sustainable development has its roots in ideas regarding sustainable forest management , which were developed in Europe during the 17th and 18th centuries. In response to a growing awareness of the depletion of timber resources in England, John Evelyn argued, in his 1662 essay Sylva , that "sowing and planting of trees had to be regarded as

10670-412: The turn of the first millennium BC , encompassed numerous cities extending from Tyre , Cydon , and Byblos to Carthage and Cádiz . In the following centuries, independent city-states of Greece , especially Athens , developed the polis , an association of male landowning citizens who collectively constituted the city. The agora , meaning "gathering place" or "assembly", was the center of

10780-446: The urban landscape. In the second half of the 20th century, deindustrialization (or " economic restructuring ") in the West led to poverty , homelessness , and urban decay in formerly prosperous cities. America's "Steel Belt" became a " Rust Belt " and cities such as Detroit , Michigan, and Gary, Indiana began to shrink , contrary to the global trend of massive urban expansion. Such cities have shifted with varying success into

10890-521: The use of resource inputs and the creation of waste , pollution and carbon emissions. The European Commission has adopted an ambitious Circular Economy Action Plan in 2020, which aims at making sustainable products the norm in the EU. It has been suggested that because of the rural poverty and overexploitation , environmental resources should be treated as important economic assets, called natural capital . Economic development has traditionally required

11000-417: The use of various materials increased in volume, diversity, and distance transported. By 2050, humanity could consume an estimated 140 billion tons of minerals, ores, fossil fuels and biomass per year (three times its current amount) unless the economic growth rate is decoupled from the rate of natural resource consumption . Sustainable use of materials has targeted the idea of dematerialization , converting

11110-432: The value of investment in human capital "), policymakers have many possible interventions to increase sustainability, in macroeconomics or purely environmental. Several studies have noted that efficient policies for renewable energy and pollution are compatible with increasing human welfare, eventually reaching a golden-rule steady state. A meta review in 2002 looked at environmental and economic valuations and found

11220-525: The volume of sewage begins to exceed manageable levels. The local government of cities takes different forms including prominently the municipality (especially in England , in the United States , India , and other British colonies ; legally, the municipal corporation ; municipio in Spain and Portugal , and, along with municipalidad , in most former parts of the Spanish and Portuguese empires) and

11330-512: The world's population lived in cities. The cultural appeal of cities also plays a role in attracting residents. Urbanization rapidly spread across Europe and the Americas and since the 1950s has taken hold in Asia and Africa as well. The Population Division of the United Nations Department of Economic and Social Affairs reported in 2014 that for the first time, more than half of the world population lives in cities. Latin America

11440-532: Was Dia , in present-day Mali , from 800 BC. Both Dhar Tichitt and Dia were founded by the same people: the Soninke , who would later also found the Ghana Empire . Another ancient site, Jenné-Jeno , in what is today Mali , has been dated to the third century BCE. According to Roderick and Susan McIntosh, Jenné-Jeno did not fit into traditional Western conceptions of urbanity as it lacked monumental architecture and

11550-660: Was a follow-up to the Millennium Declaration from the year 2000 with its eight Millennium Development Goals (MDGs), the first comprehensive global governance framework for the achievement of sustainable development. The SDGs have concrete targets (unlike the results from the Rio Process) but no methods for sanctions. They contain goals, targets and indicators for example in the areas of poverty reduction, environmental protection , human prosperity and peace . Sustainability means different things to different people, and

11660-580: Was commissioned by the Club of Rome and written by a group of scientists led by Dennis and Donella Meadows of the Massachusetts Institute of Technology . Describing the desirable "state of global equilibrium", the authors wrote: "We are searching for a model output that represents a world system that is sustainable without sudden and uncontrolled collapse and capable of satisfying the basic material requirements of all of its people." The year 1972 also saw

11770-466: Was influential in the development of the environmental movement in the 1960s. Following the publication of Rachel Carson 's Silent Spring in 1962, the developing environmental movement drew attention to the relationship between economic growth and environmental degradation . Kenneth E. Boulding , in his influential 1966 essay The Economics of the Coming Spaceship Earth , identified

11880-584: Was poverty reduction to be reached through economic growth and participation in the global trade system. The SDGs take a much more comprehensive approach to sustainable development than the MDGs did. They offer a more people-centred development agenda. Out of the 17 SDGs , for example, 11 goals contain targets related to equity, equality or inclusion, and SDG 10 is solely devoted to addressing inequality within and among countries. An unsustainable situation occurs when natural capital (the total of nature's resources)

11990-520: Was the first international document that identified education as an essential tool for achieving sustainable development and highlighted areas of action for education. ESD is a component of measurement in an indicator for Sustainable Development Goal 12 (SDG) for "responsible consumption and production". SDG 12 has 11 targets, and target 12.8 is "By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature." 20 years after

12100-493: Was very labour oriented. That region's importance for employment is also confirmed by the fact that the number of jobs in the region is much larger than the number of employed persons living in it. Earnings of persons employed in this region are the highest in the country: in 2013 the average net earnings in the country amounted to EUR 997, whereas in this region they were over EUR 90 higher. Employment structure: 69.7% services, 28.1% industry, 2.2% agriculture. It attracts 13.2% of
