28-421: Coney Island , alternatively known as Pulau Serangoon , is a 133- hectare island located off the northeastern coast of Singapore within the town of Punggol , between Pulau Ubin to its northeast and the mainland to its southwest. Land reclamation works were carried out on the island from 1975 to the 1990s, as there were plans to build residential buildings on the southern part of the island. The works narrowed

56-661: 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

84-404: 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

112-439: 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

140-542: 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

168-563: A role in climate change mitigation and adaptation . This takes place at various scales, at scales, namely "from individual farms to entire watersheds ". A World Bank report in 2006 explained: "SLM is necessary to meet the requirements of a growing population. Improper land management can lead to land degradation and a significant reduction in the productive and service (biodiversity niches, hydrology , carbon sequestration ) functions of watersheds and landscapes." The IPCC's Special Report on Climate Change and Land (SRCCL) explains

196-658: 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 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

224-401: A variety of purposes which may include for example agriculture , forestry , water resource management , human settlements and tourism . Unsustainable land managements leads to land being over- or misused which in turn degrades the land, reduces productivity and disrupts natural equilibriums. Sustainable land management (SLM) refers to practices and technologies that aim to integrate

252-462: Is "The total of arrangements, activities and inputs applied to a parcel of land." Land use categories include: forest land , cropland ( agricultural land ), grassland , wetlands , settlements and other lands . The United Nations Economic Commission for Europe (UNECE) applies the term land management in a wide context. Besides agriculture and forestry, they include the mineral extraction sector, property and estate management: "Land management

280-515: Is a combination of ヘクタール ( hekutāru ), the Japanese translation of "hectare". Land management Land management is the process of managing the use and development of land resources. One aim of sustainable land management is to prevent or reverse land degradation . Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff , and decreasing soil erosion . Land resources are used for

308-451: 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

336-558: Is part of the park connector network. The offshore island of Pulau Serangoon (Coney Island), was formerly part of the Changi SMC from 1951 to 1997, then subsumed into East Coast GRC (Siglap division) from 1997 to 2015 before transferring to Pasir Ris-Punggol GRC after the growth of Punggol. Coney Island is also a popular place for jet skiing and camping. However, this has contributed to the beaches being polluted by litter such as discarded cans, instant noodle packets and bottles. Managed by

364-454: Is the process by which the resources of land are put to good effect. It covers all activities concerned with the management of land as a resource both from an environmental and from an economic perspective. It can include farming, mineral extraction, property and estate management, and the physical planning of towns and the countryside. Sustainable land management (SLM) is a process in a charged environment between environmental protection and

392-1130: The European Union , New Zealand and Australia (since 1970). However, 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

420-542: The National Parks Board , the 81 hectares (0.81 km) nature park is home to a wide variety of habitats, including coastal forests, grasslands and mangroves. The park was officially opened by the Transport Minister and Co-ordinating Minister for Infrastructure , Khaw Boon Wan on 10 October 2015. During its first year of operation, a free-ranging Brahman cow was frequently sighted in the area. The island

448-573: 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

476-484: The Master Plan, a part of Coney Island was zoned for residential, sport and recreational use but as the land is not immediately required for development, a part of Coney Island would be kept as an interim park for the time being. The rest of the island was zoned for park use. On 10 October 2015, Coney Island Park opened to the public, with a beach stretching 2 km (1 mi) and a 2.4 km (1.5 mi) long path that

504-400: The agricultural landscapes. On the other hand, the nonstructural measures, such as the elimination of open grazing on communal grazing land and the abandonment of postharvest grazing on cultivated land, help improve the water retention capacity of the soils and reduce nonproductive evaporative water losses. In addition, the current practices of SLM attempts to sustain diverse land use mosaics at

532-490: The channel between Punggol and the island to 100m. Still, in spite of this small distance, motor launches had to be specially hired to reach the island until the opening of Coney Island Park, linked to the main island by two bridges on its western and eastern ends. Formerly known as Pulau Serangoon ( English : Serangoon Island), the island was once owned by entrepreneur siblings Aw Boon Haw and Aw Boon Par , before being sold to an Indian businessman, Ghulam Mahmood, in 1950 with

560-1142: The economic value of pasture. Land restoration and rehabilitation measures improve livelihood systems and provide both short-term positive economic returns and longer-term benefits in terms of climate change adaptation and mitigation, biodiversity and enhanced ecosystem functions and services ." Land management options exist to focus on healthy soils and to "reduce vulnerability to soil erosion and nutrient loss". Examples include "growing green manure crops and cover crops, crop residue retention, reduced/zero tillage, and maintenance of ground cover through improved grazing management". There are also land management options for farmers that build soil carbon and therefore provide important climate change mitigation benefits through carbon sequestration : "agroforestry , perennial pasture phases and use of perennial grains ". All these methods reduce soil erosion and nutrient leaching. Land management options that "do not require land use change and do not create demand for more land conversion" include: For example in Ethiopia , "over 85% of

588-561: The guarantee claim of ecosystem services on the one hand. On the other hand, it is about productivity of agriculture and forestry with respect to demographic growth and increasing pressure in land use . SLM has been defined in various reports as follows: One aim of sustainable land management is to prevent or reverse land degradation . Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff , and decreasing soil erosion . The IPCC stated that sustainable land management can play

616-467: The intention of turning the island into a resort modelled after the amusement area at Coney Island , New York. The land reclamation works begun in 1975, increasing the area of the island from 32 hectares (0.32 km) to 62 hectares (0.62 km). Further land reclamation works were carried out during the 1990s with plans to build a 50-hectare park together with the development of Punggol New Town . The Urban Redevelopment Authority (URA) said that under

644-400: The land is estimated to be moderately to severely degraded". The current practices of sustainable land management (SLM) involve a variety of structural and nonstructural elements integrated at the catchment scale, providing different roles in managing water resources . The structural measures (soil bunds, contour trenches, etc.) significantly improve infiltration and water storage potential of

672-594: The linkages between sustainable land management and climate change mitigation . The full title of the report is the "Special Report on climate change , desertification , land degradation , sustainable land management, food security , and greenhouse gas fluxes in terrestrial ecosystems". The report's summary for policy makers explains that, "Many sustainable land management technologies and practices are profitable within three to 10 years (medium confidence). While they can require upfront investment, actions to ensure sustainable land management can improve crop yields and

700-534: The management of land, water , and other environmental resources to meet human needs while ensuring long-term sustainability , ecosystem services , biodiversity , and livelihoods. Sustainable forest management is a sub-category of sustainable land management. The IPCC Sixth Assessment Report describes land management as "The sum of land-use practices (e.g., sowing , fertilising , weeding , harvesting , thinning and clear-cutting ) that take place within broader land-use categories." Land use itself

728-580: 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

756-557: 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 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
