46-555: Kurinjimala Sanctuary protects the approximately 32 hectare core habitat of the endangered Neelakurinji plant in the Kottakamboor and Vattavada villages in Devikulam Taluk, in the Idukki district of Kerala , a state in southern India . According to some historians, the earliest known inhabitants of southern India were hunter-gatherers who inhabited Kurinjimala. The sanctuary

92-661: A dash ; for example, 1-21-00.26 ha would mean 1 hectare, 21 ares, and 0.26 centiares (12,100.26 m ). The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure: In 1960, when the metric system was updated as the International System of Units (SI), the are did not receive international recognition. The International Committee for Weights and Measures ( CIPM ) makes no mention of

138-404: A double prefix is non-standard. The decimilliare is (100 mm) or roughly a four-inch-by-four-inch square. The centiare is one square metre. The deciare (rarely used) is ten square metres. The are ( / ɑːr / or / ɛər / ) is a unit of area, equal to 100 square metres ( 10 m × 10 m ), used for measuring land area. It was defined by older forms of the metric system , but

184-439: A few other units including the are (and implicitly the hectare ) whose use was limited to the measurement of land. The names centiare , deciare , decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are . The decimilliare (dma, sometimes seen in cadastre area evaluation of real estate plots) is 1 ⁄ 10,000 are or one square decimetre. Such usage of

230-465: A framework for urban planning decision-making. Another debate within the urban planning field is about who is included and excluded in the urban planning decision-making process. Most urban planning processes use a top-down approach which fails to include the residents of the places where urban planners and city officials are working. Sherry Arnstein 's "ladder of citizen participation" is often used by many urban planners and city governments to determine

276-941: A given area and thus, guides orderly development in urban, suburban and rural areas . Although predominantly concerned with the planning of settlements and communities, urban planners are also responsible for planning the efficient transportation of goods, resources, people, and waste; the distribution of basic necessities such as water and electricity; a sense of inclusion and opportunity for people of all kinds, culture and needs; economic growth or business development; improving health and conserving areas of natural environmental significance that actively contributes to reduction in CO 2 emissions as well as protecting heritage structures and built environments. Since most urban planning teams consist of highly educated individuals that work for city governments, recent debates focus on how to involve more community members in city planning processes. Urban planning

322-542: A measure of land area. The names of the older land measures of similar size are usually used, redefined as exactly one decare: The most commonly used units are in bold . One hectare is also equivalent to: The Unicode character U+33CA ㏊ SQUARE HA , in the CJK Compatibility block, is intended for compatibility with pre-existing East Asian character codes. It is not intended for use in alphabetic contexts. U+3336 ㌶ SQUARE HEKUTAARU

368-569: A particular type of bamboo from Kurinjimala. The silambam staff is known as neduvadi in Kerala , dhanta varisai in Karnataka , and karra saamu in Andhra Pradesh . 10°14′N 77°16′E  /  10.23°N 77.27°E  / 10.23; 77.27 Hectare In 1795, when the metric system was introduced, the are was defined as 100 square metres , or one square decametre , and

414-463: A tool to improve the health and well-being of people, maintaining sustainability standards. Similarly, in the early 21st century, Jane Jacobs 's writings on legal and political perspectives to emphasize the interests of residents, businesses and communities effectively influenced urban planners to take into broader consideration of resident experiences and needs while planning. Urban planning answers questions about how people will live, work, and play in

460-428: A top-down approach in master planning the physical layout of human settlements . The primary concern was the public welfare , which included considerations of efficiency, sanitation , protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom lines that focus on planning as

506-648: Is a combination of ヘクタール ( hekutāru ), the Japanese translation of "hectare". Town planning Urban planning , also known as town planning , city planning , regional planning , or rural planning in specific contexts, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas , such as transportation , communications , and distribution networks , and their accessibility . Traditionally, urban planning followed

552-538: Is an interdisciplinary field that includes civil engineering , architecture , human geography , politics , social science and design sciences . Practitioners of urban planning are concerned with research and analysis, strategic thinking, engineering architecture, urban design , public consultation , policy recommendations, implementation and management. It is closely related to the field of urban design and some urban planners provide designs for streets, parks, buildings and other urban areas. Urban planners work with

598-459: Is evidence of urban planning and designed communities dating back to the Mesopotamian , Indus Valley , Minoan , and Egyptian civilizations in the third millennium BCE . Archaeologists studying the ruins of cities in these areas find paved streets that were laid out at right angles in a grid pattern. The idea of a planned out urban area evolved as different civilizations adopted it. Beginning in

644-451: Is now outside the modern International System of Units (SI). It is still commonly used in speech to measure real estate, in particular in Indonesia, India, and in various European countries. In Russian and some other languages of the former Soviet Union , the are is called sotka (Russian: сотка : 'a hundred', i.e. 100 m or 1 ⁄ 100 hectare). It is used to describe

690-634: Is the Geographic Information System (GIS) that is used to create a model of the existing planning and then to project future impacts on the society, economy and environment. Building codes and other regulations dovetail with urban planning by governing how cities are constructed and used from the individual level. Enforcement methodologies include governmental zoning , planning permissions , and building codes , as well as private easements and restrictive covenants . With recent advances in information and communication technologies and

736-416: Is the body of scientific concepts, definitions, behavioral relationships, and assumptions that define the body of knowledge of urban planning. There are eight procedural theories of planning that remain the principal theories of planning procedure today: the rational-comprehensive approach, the incremental approach, the transactive approach, the communicative approach, the advocacy approach, the equity approach,

782-402: Is unnecessary, or even harmful, as it market efficiency allows for effective land use. A pluralist strain of political thinking argues in a similar vein that the government should not intrude in the political competition between different interest groups which decides how land is used. The traditional justification for urban planning has in response been that the planner does to the city what

828-544: The Enlightenment period , several European rulers ambitiously attempted to redesign capital cities. During the Second French Empire , Baron Georges-Eugène Haussmann , under the direction of Napoleon III , redesigned the city of Paris into a more modern capital, with long, straight, wide boulevards. Planning and architecture went through a paradigm shift at the turn of the 20th century. The industrialized cities of

874-491: The Internet of Things , an increasing number of cities are adopting technologies such as crowdsorced mobile phone sensing and machine learning to collect data and extract useful information to help make informed urban planning decisions. An urban planner is a professional who works in the field of urban planning for the purpose of optimizing the effectiveness of a community's land use and infrastructure. They formulate plans for

920-618: The are in the 2019 edition of the SI brochure, but classifies the hectare as a "Non-SI unit accepted for use with the International System of Units". In 1972, the European Economic Community (EEC) passed directive 71/354/EEC, which catalogued the units of measure that might be used within the Community. The units that were catalogued replicated the recommendations of the CGPM, supplemented by

966-549: The water supply , identifying transportation patterns, recognizing food supply demands, allocating healthcare and social services, and analyzing the impact of land use. In order to predict how cities will develop and estimate the effects of their interventions, planners use various models. These models can be used to indicate relationships and patterns in demographic, geographic, and economic data. They might deal with short-term issues such as how people move through cities, or long-term issues such as land use and growth. One such model

1012-511: The 19th century grew at a tremendous rate. The evils of urban life for the working poor were becoming increasingly evident as a matter of public concern. The laissez-faire style of government management of the economy, in fashion for most of the Victorian era , was starting to give way to a New Liberalism that championed intervention on the part of the poor and disadvantaged. Around 1900, theorists began developing urban planning models to mitigate

1058-454: The 8th century BCE, Greek city states primarily used orthogonal (or grid-like) plans. Hippodamus of Miletus (498–408 BC), the ancient Greek architect and urban planner, is considered to be "the father of European urban planning", and the namesake of the "Hippodamian plan" (grid plan) of city layout. The ancient Romans also used orthogonal plans for their cities. City planning in the Roman world

1104-758: The Multiple Nuclei Model among others. Participatory planning is an urban planning approach that involves the entire community in the planning process. Participatory planning in the United States emerged during the 1960s and 1970s. Technical aspects of urban planning involve the application of scientific, technical processes, considerations and features that are involved in planning for land use , urban design , natural resources , transportation , and infrastructure . Urban planning includes techniques such as: predicting population growth , zoning , geographic mapping and analysis, analyzing park space, surveying

1150-458: The SI, being equivalent to a square hectometre. It is widely used throughout the world for the measurement of large areas of land, and it is the legal unit of measure in domains concerned with land ownership, planning, and management , including law ( land deeds ), agriculture, forestry , and town planning throughout the European Union , New Zealand and Australia (since 1970). However,

1196-940: The United Kingdom, the United States, Myanmar (Burma), and to some extent Canada, use the acre instead of the hectare for measuring surface or land area. Some countries that underwent a general conversion from traditional measurements to metric measurements (e.g. Canada) required a resurvey when units of measure in legal descriptions relating to land were converted to metric units. Others, such as South Africa, published conversion factors which were to be used particularly "when preparing consolidation diagrams by compilation". In many countries, metrification redefined or clarified existing measures in terms of metric units. The following legacy units of area have been redefined as being equal to one hectare: In Mexico, land area measurements are commonly given as combinations of hectares, ares, and centiares. These are commonly written separated by

1242-418: The United States. The United Nations Department of Economic and Social Affairs predicted in 2018 that around 2.5 billion more people occupy urban areas by 2050 according to population elements of global migration. New planning theories have adopted non-traditional concepts such as Blue Zones and Innovation Districts to incorporate geographic areas within the city that allow for novel business development and

1288-530: The cognate fields of civil engineering, landscape architecture , architecture, and public administration to achieve strategic, policy and sustainability goals. Early urban planners were often members of these cognate fields though today, urban planning is a separate, independent professional discipline. The discipline of urban planning is the broader category that includes different sub-fields such as land-use planning , zoning , economic development , environmental planning , and transportation planning . Creating

1334-545: The coming of the Renaissance many new cities were enlarged with newly planned extensions. From the 15th century on, much more is recorded of urban design and the people that were involved. In this period, theoretical treatises on architecture and urban planning start to appear in which theoretical questions around planning the main lines, ensuring plans meet the needs of the given population and so forth are addressed and designs of towns and cities are described and depicted. During

1380-453: The consequences of the industrial age , by providing citizens, especially factory workers, with healthier environments. The following century would therefore be globally dominated by a central planning approach to urban planning, not representing an increment in the overall quality of the urban realm. At the beginning of the 20th century, urban planning began to be recognized as a separate profession. The Town and Country Planning Association

1426-469: The degree of inclusivity or exclusivity of their urban planning. One main source of engagement between city officials and residents are city council meetings that are open to the residents and that welcome public comments. Additionally, in US there are some federal requirements for citizen participation in government-funded infrastructure projects. Participatory urban planning has been criticized for contributing to

1472-506: The dekare/decare daa (1,000 m ) and are (100 m ) are not officially "accepted for use", they are still used in some contexts. The hectare ( / ˈ h ɛ k t ɛər , - t ɑː r / ), although not a unit of SI, is the only named unit of area that is accepted for use with SI units . The name was coined in French, from the Latin ārea . In practice the hectare is fully derived from

1518-553: The development and management of urban and suburban areas. They typically analyze land use compatibility as well as economic, environmental, and social trends. In developing any plan for a community (whether commercial, residential, agricultural, natural or recreational), urban planners must consider a wide array of issues including sustainability , existing and potential pollution , transport including potential congestion , crime , land values, economic development, social equity, zoning codes, and other legislation. The importance of

1564-400: The engineer or architect does to the home, that is, make it more amenable to the needs and preferences of its inhabitants. The widely adopted consensus-building model of planning, which seeks to accommodate different preferences within the community has been criticized for being based upon, rather than challenging, the power structures of the community. Instead, agonism has been proposed as

1610-469: The hectare (" hecto- " + "are") was thus 100 ares or 1 ⁄ 100  km (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units ( SI ), the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though

1656-448: The ideas of modernism in urban planning led to higher crime rates and social problems. In the second half of the 20th century, urban planners gradually shifted their focus to individualism and diversity in urban centers. Urban planners studying the effects of increasing congestion in urban areas began to address the externalities, the negative impacts caused by induced demand from larger highway systems in western countries such as in

1702-879: The plans requires a thorough understanding of penal codes and zonal codes of planning. Another important aspect of urban planning is that the range of urban planning projects include the large-scale master planning of empty sites or Greenfield projects as well as small-scale interventions and refurbishments of existing structures, buildings and public spaces. Pierre Charles L'Enfant in Washington, D.C., Daniel Burnham in Chicago, Lúcio Costa in Brasília and Georges-Eugene Haussmann in Paris planned cities from scratch, and Robert Moses and Le Corbusier refurbished and transformed cities and neighborhoods to meet their ideas of urban planning. There

1748-476: The prioritization of infrastructure that would assist with improving the quality of life of citizens by extending their potential lifespan. Planning practices have incorporated policy changes to help address anthropogenic (human caused) climate change . London began to charge a congestion charge for cars trying to access already crowded places in the city. Cities nowadays stress the importance of public transit and cycling by adopting such policies. Planning theory

1794-652: The radical approach, and the humanist or phenomenological approach. Some other conceptual planning theories include Ebenezer Howard 's The Three Magnets theory that he envisioned for the future of British settlement, also his Garden Cities , the Concentric Model Zone also called the Burgess Model by sociologist Ernest Burgess , the Radburn Superblock that encourages pedestrian movement, the Sector Model and

1840-553: The sanctuary area. The sanctuary is home to threatened species of elephant , gaur , nilgiri tahr and deer . The new sanctuary is contiguous to the Chinnar Wildlife Sanctuary to the northwest, Manjampatti Valley in Amaravati Reserve Forest of Indira Gandhi Wildlife Sanctuary to the northeast, Eravikulam National Park and Anamudi Shola National Park to the west, Pampadum Shola National Park to

1886-580: The size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large. Many Russian dachas are 6 ares in size (in Russian, шесть соток ). The decare or dekare ( / ˈ d ɛ k ɑːr , - ɛər / ) is derived from deca and are , and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as

1932-692: The south and the proposed Palani Hills National Park to the east. The sanctuary provides continuity and connectivity to these five protected areas. The Indian martial art of Silambam , known to be practiced by the Tamil people , originated in the Kurinji hills. It derives its name from the Tamil word silam , meaning hill, and the Kannada word bamboo from which the English word bamboo originates. The term silambambu referred to

1978-602: The urban planner is increasing in the 21st century, as modern society begins to face issues of increased population growth, climate change and unsustainable development. An urban planner could be considered a green collar professional. Some researchers suggest that urban planners, globally, work in different " planning cultures ", adapted to their cities and cultures. However, professionals have identified skills, abilities, and basic knowledge sets that are common to urban planners across regional and national boundaries. The school of neoclassical economics argues that planning

2024-619: Was declared by the Kerala Forest Minister Benoy Viswam at the Neelakurinji Fest at Munnar on 7 October 2006. During the 2006 bloom, massive flowering of Neelakurinji attracted nearly one million people to Munnar and other places. The Government notification said that the sanctuary would ensure the long-term protection of the unique biodiversity of the area, especially Strobilanthes kunthiana and its habitat. Private land holdings having legal titles are excluded from

2070-573: Was developed for military defense and public convenience. The spread of the Roman Empire subsequently spread the ideas of urban planning. As the Roman Empire declined, these ideas slowly disappeared. However, many cities in Europe still held onto the planned Roman city center. Cities in Europe from the 9th to 14th centuries, often grew organically and sometimes chaotically. But in the following centuries with

2116-617: Was founded in 1899 and the first academic course in Great Britain on urban planning was offered by the University of Liverpool in 1909. In the 1920s, the ideas of modernism and uniformity began to surface in urban planning, and lasted until the 1970s. In 1933, Le Corbusier presented the Radiant City, a city that grows up in the form of towers, as a solution to the problem of pollution and over-crowding. But many planners started to believe that
