69-504: When compared to older gated communities in Pilar , Nordelta's natural features (trees, plants, etc.) stand out as too "artificial", because Pilar's trees, for instance, are very large and mature compared to Nordelta's miniature trees. Because of its size and relatively affluent population, Nordelta has been able to develop and maintain a varied array of commercial and services infrastructure, including swimming pools , soccer and tennis fields,

138-711: A sink or a source of carbon, depending on the specific wetland. If they function as a carbon sink, they can help with climate change mitigation . However, wetlands can also be a significant source of methane emissions due to anaerobic decomposition of soaked detritus , and some are also emitters of nitrous oxide . Humans are disturbing and damaging wetlands in many ways, including oil and gas extraction , building infrastructure, overgrazing of livestock , overfishing , alteration of wetlands including dredging and draining, nutrient pollution , and water pollution . Wetlands are more threatened by environmental degradation than any other ecosystem on Earth, according to

207-402: A frequency and duration to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally included swamps, marshes, bogs, and similar areas.' For each of these definitions and others, regardless of the purpose, hydrology is emphasized (shallow waters, water-logged soils). The soil characteristics and

276-1248: A polar climate, wetland temperatures can be as low as −50 °C (−58 °F). Peatlands in arctic and subarctic regions insulate the permafrost , thus delaying or preventing its thawing during summer, as well as inducing its formation. The amount of precipitation a wetland receives varies widely according to its area. Wetlands in Wales , Scotland , and western Ireland typically receive about 1,500 mm (59 in) per year. In some places in Southeast Asia , where heavy rains occur, they can receive up to 10,000 mm (390 in). In some drier regions, wetlands exist where as little as 180 mm (7.1 in) precipitation occurs each year. Temporal variation: Surface flow may occur in some segments, with subsurface flow in other segments. Wetlands vary widely due to local and regional differences in topography , hydrology , vegetation , and other factors, including human involvement. Other important factors include fertility, natural disturbance, competition, herbivory , burial and salinity. When peat accumulates, bogs and fens arise. The most important factor producing wetlands

345-540: A portion of the overall water cycle, which also includes atmospheric water (precipitation) and groundwater . Many wetlands are directly linked to groundwater and they can be a crucial regulator of both the quantity and quality of water found below the ground. Wetlands that have permeable substrates like limestone or occur in areas with highly variable and fluctuating water tables have especially important roles in groundwater replenishment or water recharge. Substrates that are porous allow water to filter down through

414-509: A rectangular plaza which in turn gives rise to the trace the streets and a grid amanzanamiento. The square is graced Ginkgo biloba , planted between 1958 and 1962. Treaty of Pilar . Signed here on February 23, 1820, it marked the origin of the federal system of government and made the city the "cradle of federalism" in Argentina. The pact, signed in the original chapel of Pilar by Francisco Ramírez, Estanislao López, and Manuel de Sarratea, ended

483-400: A shopping mall, a medical center, a sports club, four private schools , playgrounds , saunas , and more. Over the years, there has been steady development of new neighborhoods as more and more people moved in. Also, it was one of the first places in Argentina to have a Telecom communications network of a totally new generation. The Nordelta project has been criticised for encroaching upon

552-422: A strong influence on wetland water chemistry, particularly in coastal wetlands and in arid and semiarid regions with large precipitation deficits. Natural salinity is regulated by interactions between ground and surface water, which may be influenced by human activity. Carbon is the major nutrient cycled within wetlands. Most nutrients, such as sulfur , phosphorus , carbon , and nitrogen are found within

621-410: A unique kind of wetland where lush plant growth and slow decay of dead plants (under anoxic conditions) results in organic peat accumulating; bogs, fens, and mires are different names for peatlands. Variations of names for wetland systems: Some wetlands have localized names unique to a region such as the prairie potholes of North America's northern plain, pocosins , Carolina bays and baygalls of

690-508: A wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". Sometimes a precise legal definition of a wetland is required. The definition used for regulation by the United States government is: 'The term "wetlands" means those areas that are inundated or saturated by surface or ground water at

759-422: A wetland system includes its plants ( flora ) and animals ( fauna ) and microbes (bacteria, fungi). The most important factor is the wetland's duration of flooding. Other important factors include fertility and salinity of the water or soils. The chemistry of water flowing into wetlands depends on the source of water, the geological material that it flows through and the nutrients discharged from organic matter in

828-403: A wetland) affects hydro-periods (temporal fluctuations in water levels) by controlling the water balance and water storage within a wetland. Landscape characteristics control wetland hydrology and water chemistry. The O 2 and CO 2 concentrations of water depend upon temperature , atmospheric pressure and mixing with the air (from winds or water flows). Water chemistry within wetlands

897-558: A whole. To replace these wetland ecosystem services , enormous amounts of money would need to be spent on water purification plants, dams, levees, and other hard infrastructure, and many of the services are impossible to replace. Floodplains and closed-depression wetlands can provide the functions of storage reservoirs and flood protection. The wetland system of floodplains is formed from major rivers downstream from their headwaters . "The floodplains of major rivers act as natural storage reservoirs, enabling excess water to spread out over

966-577: A wide area, which reduces its depth and speed. Wetlands close to the headwaters of streams and rivers can slow down rainwater runoff and spring snowmelt so that it does not run straight off the land into water courses. This can help prevent sudden, damaging floods downstream." Notable river systems that produce wide floodplains include the Nile River , the Niger river inland delta, the Zambezi River flood plain,

1035-515: Is a city in the province of Buenos Aires , Argentina with a population of 299,077 as per the 2010 census [ INDEC ] . It is part of the Greater Buenos Aires urban conurbation and is the seat of the administrative division of Pilar Partido . Since the early 1990s, Pilar has gained an increasingly upscale profile due to the development of numerous gated communities, country clubs and polo fields. The rural outpost that later became Pilar

It is celebrated on February 23, the anniversary of the peace agreement signed by Manuel de Sarratea , Governor of Buenos Aires; Estanislao López , Governor of Santa Fe; and Francisco Ramírez , governor of Entre Ríos. The treaty, signed in 1820, laid the foundation of the federal system of government today prevailing in Argentina. Pilar recalls

1173-440: Is determined by the pH , salinity , nutrients, conductivity , soil composition, hardness , and the sources of water. Water chemistry varies across landscapes and climatic regions. Wetlands are generally minerotrophic (waters contain dissolved materials from soils) with the exception of ombrotrophic bogs that are fed only by water from precipitation. Because bogs receive most of their water from precipitation and humidity from

1242-629: Is either freshwater , brackish or saltwater . The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds , cattails and sedges . Swamps are dominated by woody vegetation such as trees and shrubs (although reed swamps in Europe are dominated by reeds, not trees). Mangrove forest are wetlands with mangroves , halophytic woody plants that have evolved to tolerate salty water . Examples of wetlands classified by

1311-412: Is hydrology, or flooding . The duration of flooding or prolonged soil saturation by groundwater determines whether the resulting wetland has aquatic, marsh or swamp vegetation . Other important factors include soil fertility, natural disturbance, competition, herbivory , burial, and salinity. When peat from dead plants accumulates, bogs and fens develop. Wetland hydrology is associated with

1380-658: Is known in Argentina as the National Capital of Polo. The Argentina Polo Association is headquartered in Pando-Carabassa Castle, built in the late nineteenth century. The site has nine fields and is home to the most important tournaments in the country. Wetland A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water , either permanently, for years or decades, or only seasonally. Flooding results in oxygen -poor ( anoxic ) processes taking place, especially in

1449-451: Is the only place in the world where both crocodiles and alligators coexist. The saltwater crocodile inhabits estuaries and mangroves. Snapping turtles also inhabit wetlands. Birds , particularly waterfowl and waders use wetlands extensively. Mammals of wetlands include numerous small and medium-sized species such as voles , bats , muskrats and platypus in addition to large herbivorous and apex predator species such as

1518-545: Is usually saturated with water". More precisely, wetlands are areas where "water covers the soil , or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". A patch of land that develops pools of water after a rain storm would not necessarily be considered a "wetland", even though the land is wet. Wetlands have unique characteristics: they are generally distinguished from other water bodies or landforms based on their water level and on

1587-492: The Millennium Ecosystem Assessment from 2005. Methods exist for assessing wetland ecological health . These methods have contributed to wetland conservation by raising public awareness of the functions that wetlands can provide. Since 1971, work under an international treaty seeks to identify and protect " wetlands of international importance ." A simplified definition of wetland is "an area of land that

1656-666: The Pantanal in South America, and the Sundarbans in the Ganges - Brahmaputra delta. Wetlands contribute many ecosystem services that benefit people. These include for example water purification , stabilization of shorelines, storm protection and flood control . In addition, wetlands also process and condense carbon (in processes called carbon fixation and sequestration ), and other nutrients and water pollutants . Wetlands can act as

1725-578: The Paraná wetlands, the habitat for wildlife and, with other processes such as urban sprawl and the extension of farming, contributing to wildfires and reducing the capacity of the land to absorb rainfall. The people of Nordelta created the Nordelta Foundation , in an effort to help improve the quality of life of poor people living in Las Tunas , a shantytown located very close to Nordelta. The district

Pilar

1863-444: The atmosphere , their water usually has low mineral ionic composition. In contrast, wetlands fed by groundwater or tides have a higher concentration of dissolved nutrients and minerals. Fen peatlands receive water both from precipitation and ground water in varying amounts so their water chemistry ranges from acidic with low levels of dissolved minerals to alkaline with high accumulation of calcium and magnesium . Salinity has

1932-576: The beavers , coypu , swamp rabbit , Florida panther , jaguar , and moose . Wetlands attract many mammals due to abundant seeds, berries, and other vegetation as food for herbivores, as well as abundant populations of invertebrates, small reptiles and amphibians as prey for predators. Invertebrates of wetlands include aquatic insects such as dragonflies , aquatic bugs and beetles , midges, mosquitos , crustaceans such as crabs, crayfish, shrimps, microcrustaceans, mollusks like clams, mussels, snails and worms. Invertebrates comprise more than half of

2001-607: The soils . Wetlands form a transitional zone between waterbodies and dry lands , and are different from other terrestrial or aquatic ecosystems due to their vegetation 's roots having adapted to oxygen-poor waterlogged soils . They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals , with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus . Wetlands exist on every continent , except Antarctica . The water in wetlands

2070-544: The 58 kilometres (36 mi) commute to Buenos Aires , and Pilar subsequently became a growing commuter town . Pilar grew further after the construction in the late 1960s of a freeway along the stretch of National Route 8 to Buenos Aires, and with the establishment in 1970 of the local industrial district , the Parque Industrial Pilar , which grew to be among the largest in South America and home to 200 national and international companies.

Wetlands are found throughout the world in different climates. Temperatures vary greatly depending on the location of the wetland. Many of the world's wetlands are in the temperate zones , midway between the North or South Poles and

2484-494: The US, the best known classifications are the Cowardin classification system and the hydrogeomorphic (HGM) classification system. The Cowardin system includes five main types of wetlands: marine (ocean-associated), estuarine (mixed ocean- and river-associated), riverine (within river channels), lacustrine (lake-associated) and palustrine (inland nontidal habitats). Peatlands are

2553-610: The United States' commercial fish and shellfish stocks depend solely on estuaries to survive. Amphibians such as frogs and salamanders need both terrestrial and aquatic habitats in which to reproduce and feed. Because amphibians often inhabit depressional wetlands like prairie potholes and Carolina bays, the connectivity among these isolated wetlands is an important control of regional populations. While tadpoles feed on algae, adult frogs forage on insects. Frogs are sometimes used as an indicator of ecosystem health because their thin skin permits absorption of nutrients and toxins from

2622-570: The advent of bricks as building material in the 19th century, the old wooden cross was replaced by masonry. The Site of the Miracle . The site, known originally as Rosendo's Post, where the miracle of the Virgin of Luján reportedly took place in 1630. There are two milestones that make reference to the miracle: a small altar with the image of the Virgin of Luján; and an old adobe chapel. The Ministry of Culture of

2691-504: The development was one of the locations of the "Soltando Amarras" Bioflow program. A severe car accident took place in Nordelta, on October 18, 2009. Four people died when a car sunk into an artificial lake inside the property. In late 2021, there was an invasion of carpinchos (capybaras), which destroyed lawns, bit dogs, caused traffic accidents, and deposited excrement to a point where some residents were forced to fence their lawns from their encroachment. Ecologist Enrique Viale said it

2760-485: The dream of living in the wild – because the people who buy those homes want nature, but without the mosquitoes, snakes or capybaras ". The vast Paraná wetlands have been encroached upon by urban sprawl and cattle and soy farmers, partly responsible for wildfires that have destroyed vast areas. Wetland projects like Nordelta prevent the land from absorbing rains, so extreme rainfall leads to flooding of nearby, poorer, neighbourhoods. Pilar, Buenos Aires Pilar

2829-779: The economic and social environment of the region. The nuclear family, made up of a married couple with professional jobs and their children, is the most common. Many families can afford to hire servants, which helps them manage a dual-income household while still being involved in their children's lives. Education and extracurricular activities are highly valued, allowing children to develop both academically and personally. Extended families are less common in Nordelta compared to other areas of Argentina. However, close relationships with extended family members, like grandparents, are maintained through childcare and family gatherings, even if they don't live together. Single-parent and blended families are also present, but they may face more challenges due to

2898-622: The equator. In these zones, summers are warm and winters are cold, but temperatures are not extreme. In subtropical zone wetlands, such as along the Gulf of Mexico , average temperatures might be 11 °C (52 °F). Wetlands in the tropics are subjected to much higher temperatures for a large portion of the year. Temperatures for wetlands on the Arabian Peninsula can exceed 50 °C (122 °F) and these habitats would therefore be subject to rapid evaporation. In northeastern Siberia , which has

2967-603: The first polo fields beginning in the late 19th century and of a number of country clubs from 1948 onward, as well as the development of numerous gated communities beginning in the 1990s, gave Pilar an increasingly upscale profile in subsequent years. Numerous visitor and tourist attractions are located in the city. These include the Parish of Our Lady of the Pillar (1856); the October 12 Plaza facing it (both National Historic Monuments );

3036-494: The following areas: According to the Ramsar Convention: The economic worth of the ecosystem services provided to society by intact, naturally functioning wetlands is frequently much greater than the perceived benefits of converting them to 'more valuable' intensive land use – particularly as the profits from unsustainable use often go to relatively few individuals or corporations, rather than being shared by society as

3105-610: The high costs of living in such an affluent area. Single-parent families, in particular, might struggle financially compared to dual-income households. Blended families may encounter difficulties fitting into the traditional family model that still exists in these communities. However, both types of families are becoming more accepted as Argentine society evolves. Child-free families, especially among younger, career-focused couples, are also more common in Nordelta. These families often choose not to have children due to their lifestyle preferences. While there may be some social pressure to follow

3174-483: The historic pact with protocol events, conferences and art festivals, among other activities. Our Lady of the Pilar . Each October 12, the community of Pilar and the whole Party celebrated the feast of their patron saint, the Virgin of Pilar. He remembers when, in 1729, a local indigenous man exposed to public worship an image of the Virgin in a chapel erected on his property. In addition to the liturgical activities, including

Some notable points of interest in Pilar are: October 12 Square . Declared a National Historic Landmark on May 21, 1942. The city has an urban design around

3312-464: The interface between truly terrestrial ecosystems and aquatic systems, making them inherently different from each other, yet highly dependent on both." In environmental decision-making, there are subsets of definitions that are agreed upon to make regulatory and policy decisions. Under the Ramsar international wetland conservation treaty , wetlands are defined as follows: An ecological definition of

3381-462: The known animal species in wetlands, and are considered the primary food web link between plants and higher animals (such as fish and birds). Depending on a wetland's geographic and topographic location, the functions it performs can support multiple ecosystem services , values, or benefits. United Nations Millennium Ecosystem Assessment and Ramsar Convention described wetlands as a whole to be of biosphere significance and societal importance in

3588-832: The plants and animals controlled by the wetland hydrology are often additional components of the definitions. Wetlands can be tidal (inundated by tides) or non-tidal. The water in wetlands is either freshwater , brackish , saline , or alkaline . There are four main kinds of wetlands – marsh , swamp , bog , and fen (bogs and fens being types of peatlands or mires ). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types. Sub-types include mangrove forests , carrs , pocosins , floodplains , peatlands, vernal pools , sinks , and many others. The following three groups are used within Australia to classify wetland by type: Marine and coastal zone wetlands, inland wetlands and human-made wetlands. In

3657-427: The provinces of Entre Ríos and Santa Fe against Buenos Aires. The Parish of Our Lady of the Pillar was consecrated in 1856, and the partido (county) of Pilar was established in 1864, its first municipal mayor being Tomás Márquez. A Buenos Aires and Pacific Railway line, its first, reached the town in 1886, and by 1895 nearly 10,000 inhabitants lived in Pilar. The opening of National Route 8 in 1934 eased

3726-412: The signing of the Treaty of Pilar. Cross of Pilar . Located on the corner of the intersection of Pedro Lagrave and Paraná streets, it's believed to have been placed in 1790 by Spanish missionaries traveling north from Buenos Aires; another version has it that this cross was placed as a guidepost when the original settlement was moved to its current location. The first mass in Pilar was held here, and with

3795-429: The soil and underlying rock into aquifers which are the source of much of the world's drinking water . Wetlands can also act as recharge areas when the surrounding water table is low and as a discharge zone when it is high. Mangroves , coral reefs , salt marsh can help with shoreline stabilization and storm protection. Tidal and inter-tidal wetland systems protect and stabilize coastal zones. Coral reefs provide

3864-537: The soil of wetlands. Anaerobic and aerobic respiration in the soil influences the nutrient cycling of carbon, hydrogen, oxygen, and nitrogen, and the solubility of phosphorus thus contributing to the chemical variations in its water. Wetlands with low pH and saline conductivity may reflect the presence of acid sulfates and wetlands with average salinity levels can be heavily influenced by calcium or magnesium. Biogeochemical processes in wetlands are determined by soils with low redox potential. The life forms of

3933-412: The soils and plants at higher elevations. Plants and animals may vary within a wetland seasonally or in response to flood regimes. There are four main groups of hydrophytes that are found in wetland systems throughout the world. Submerged wetland vegetation can grow in saline and fresh-water conditions. Some species have underwater flowers, while others have long stems to allow the flowers to reach

4002-515: The sources of water include tidal wetlands , where the water source is ocean tides ); estuaries , water source is mixed tidal and river waters; floodplains , water source is excess water from overflowed rivers or lakes; and bogs and vernal ponds , water source is rainfall or meltwater . The world's largest wetlands include the Amazon River basin , the West Siberian Plain ,

4071-406: The spatial and temporal dispersion, flow, and physio-chemical attributes of surface and ground waters. Sources of hydrological flows into wetlands are predominantly precipitation , surface water (saltwater or freshwater), and groundwater. Water flows out of wetlands by evapotranspiration , surface flows and tides , and subsurface water outflow. Hydrodynamics (the movement of water through and from

4140-709: The surface of the water. When trees and shrubs comprise much of the plant cover in saturated soils, those areas in most cases are called swamps . The upland boundary of swamps is determined partly by water levels. This can be affected by dams Some swamps can be dominated by a single species, such as silver maple swamps around the Great Lakes . Others, like those of the Amazon basin , have large numbers of different tree species. Other examples include cypress ( Taxodium ) and mangrove swamps. Many species of fish are highly dependent on wetland ecosystems. Seventy-five percent of

Reptiles such as snakes , lizards , turtles , alligators and crocodiles are common in wetlands of some regions. In freshwater wetlands of the Southeastern US, alligators are common and a freshwater species of crocodile occurs in South Florida. The Florida Everglades

4347-530: The traditional family model, Nordelta's progressive, upscale community is increasingly open to accepting various family types. Environmentalists disapprove of Nordelta because it is built on the wetlands of the River Paraná , a major river second only to the Amazon in South America in terms of size. Enrique Viale said "Wealthy real-estate developers with government backing have to destroy nature in order to sell clients
